DETAILED DESCRIPTION

[0067] Now embodiments of the invention will be described with reference to the accompanying drawings, in which like reference signs represent like components.

[0068] Please refer to Figs. 1 and 2, in which Fig. 1 is a schematic perspective view of a safety seat according to a first embodiment of the invention in an unfolded state, and Fig. 2 is a schematic right-side view of Fig. 1. The safety seat 1 in this embodiment is suitable for carrying infants, and the safety seat 1 includes a base too, a body 200, and a supporting foot 300. Among them, the base too includes fixing portion 110, the body 200 is assembled on the base too, the supporting foot 300 is slidably and pivotably connected to the base too, and the supporting foot 300 and the fixing portion 110 are arranged on opposite sides of the base too respectively along a longitudinal direction L.

[0069] Please also refer to Fig. 3, which is a schematic right-side view of the safety seat in Fig. 1 when the fixing portion is unfolded. In detail, the safety seat l is suitable for being installed on a car seat, wherein bottoms of the base too on both of left and right sides are respectively provided with slide rails extending along the longitudinal direction L, and each of the fixing portion no is, for example, a hollow component corresponding to a shape of a fixing member of the car seat. In this embodiment, a number of the fixing portion no is two, and the two fixing portion no are slidably disposed on the slide rails on the left and right sides respectively. Thus, the user can assemble the fixing portion no on the fixing member of the car seat, so as to fix the safety seat l. After use, the user only needs to unlatch the fixing portion no from the fixing member to detach the safety seat l from a car. In other words, the base too of the safety seat l can be selectively fixed to the car seat through the fixing portion no.

[0070] Please refer to Figs. 2 and 4, in which Fig. 4 is a schematic right-side view of the safety seat in Fig. 1 when both of the fixing portion and the supporting foot are fully unfolded. Preferably, the supporting foot 300 includes a supporting portion 310, a sleeve portion 330, and an extending portion 340. Among them, the supporting portion 310 is arranged at an end of the supporting foot 300, and at least one part of the extending portion 340 is inserted into the sleeve portion 330. The supporting portion 310 can be extended and retracted along an extension direction of the supporting foot 300. The user can insert the extending portion 340 into the sleeve portion 330 or extend the extending portion 340 from the sleeve portion 330, and the supporting portion 310 can abut against a rear seat pedal of the car, such that the safety seat 1 can be stably fixed to the car seat.

[0071] In addition, the body 200 in this embodiment can be assembled on the base too in different manners. Please refer to Fig. 5, which is a schematic right-side view of the safety seat in Fig. 1 when the body is arranged on the base in another direction. Specifically, the base too is formed with a plurality of holes for assembling in the longitudinal direction L, and the body 200 has a convex column at a bottom corresponding to shapes of the holes. When the passenger is an older child, the user can unlatch the convex column of the body 200 from the holes of the base too, and rotate the body 200 such that the convex column is engaged with another hole, so as to re-install the body 200 on the base too in a direction opposite to the original assembling direction. In Preferably, the contact surface between the base too and the body 200 is an arc surface and forms a limiting groove, and when the body 200 is assembled on the base too, a small range of sliding can be performed along the limiting groove in the longitudinal direction L in order to adjust a sitting angle. Since this part is not the core technology focus of this application, it will not be redundantly described here.

[0072] Please refer to Fig. 6, which is a schematic right-side view of the safety seat in Fig. 1 in a folded state. The safety seat l in this embodiment can be switched between the unfolded state and the folded state. When the child needs to use the safety seat l, the user can unfold the supporting foot in respect to the base too as shown in Figs l to 5; and when the safety seat 1 is to be stored after being used, the supporting foot 300 can be folded in respect to the base too as shown in Fig. 6. Thus, not only an overall volume occupied by the safety seat 1 can be reduced, but also size-related specifications of the safety seat 1 can be met, so it is more convenient to use. [0073] How the supporting foot 300 is folded in respect to the base too will be described in detail as below. Please refer to Figs. 7 and 8, in which Fig. 7 is a schematic perspective view of the safety seat in Fig. 1 in another angle, and Fig. 8 is schematic sectional view of Fig. 7 along X-X section. As shown, the safety seat 1 in this embodiment further includes a sliding member 400, and the sliding member 400 is slidably disposed on a bottom of the base too, and the supporting foot 300 is pivotally connected to the sliding member 400. In detail, the base too is formed with an accommodating space S at the bottom, and at least one part of the supporting foot 300 and the sliding member 400 are selectively received in the accommodating space S. Further, the sliding member 400 includes a body portion 410, and an opening O is formed on the body portion 410, and a part of the supporting foot 300 is selectively accommodated in the sliding member 400 through the opening O. Thus, when the user needs to use the supporting foot 300 of the safety seat 1, the sliding member 400 can be slid out of the accommodating space S in respect to the base too, and the supporting foot 300 can be pivoted to the unfolded state as shown in Fig. 1 in respect to the sliding member 400; and when the user does not need to use the supporting foot 300, the supporting foot 300 can be turned into the sliding member 400 through the opening O, and the sliding member 400 can be slid into the accommodating space S, so as to form the folded state as shown in Fig. 6.

[0074] Further, in order to prevent the sliding member 400 from being retracted into the accommodating space S due to the pushing of inner sides of the legs of the infant in the unfolded state, preferably, the safety seat 1 further includes a latching member 500, and the latching member 500 is pivotally connected to the base too, and the sliding member 400 further includes a positioning portion 420, and the latching member 500 is selectively latched to the positioning portion 420. As shown in Fig. 8, the sliding member 400 may slide in respect to the base too along the longitudinal direction L, and the supporting foot 300 is pivotally connected to a front end of the sliding member 400 in the longitudinal direction L, and the latching member 500 and the positioning portion 420 are arranged at a rear end of the sliding member 400 in the longitudinal direction L. Thusly, when the sliding member 400 slides out in respect to the base too and the supporting foot 300 is unfolded in respect to the base too, the latching member 500 will be latched with the positioning portion 420 at the rear end of the sliding member 400 in the longitudinal direction L, and fix the sliding member 400 at a position of the unfolded state. Preferably, the base further includes at least one limiting member 130, and the limiting member 130 is, for example, a positioning pin or a convex column, and the body portion 410 of the sliding member 400 is formed with at least one sliding slot 412. Number and position of the sliding slot 412 are corresponding to those of the limiting member 130, and the limiting member 130 is slidably disposed in the sliding slot 412, thereby guiding sliding direction of the sliding member 400 and limiting a sliding stroke.

[0075] In addition, the safety seat 1 in this embodiment also has a function of automatically unlatching the sliding member 400 when the supporting foot 300 is folded in respect to the base too. Please refer to Figs. 9 and 10, in which Fig. 9 is a schematic view of the safety seat in Fig. 8 when the supporting foot is in a folded process, and Fig. 10 is a schematic view of the safety seat in Fig. 8 when the supporting foot is fully folded. As shown, the supporting foot 300 further includes an unlatching portion 320, and the unlatching portion 320 is, for example, an annular flange located on an outer periphery of the supporting foot 300, and the latching member 500 is arranged on a pivoting path of the unlatching portion 320. With such arrangement, when the supporting foot 300 passes through the position in Fig. 9 in a clockwise direction from the position in the unfolded state shown in Fig. 8 and is finally turned into the body portion 410 of the sliding member 400, the unlatching portion 320 will abut against the latching member 500, causing the latching member 500 to temporarily deviate from the rear end of the positioning portion 420 in the longitudinal direction L, so that the latching member 500 and the sliding member 400 are no longer latched to each other, and the sliding member 400 can be slid into the accommodating space S. It would be noted, in other possible embodiments, the unlatching portion 320 can also be integrated with the supporting portion 310, that is, when the supporting foot 300 is turned into the sliding member 400, unlatching will be performed by the supporting portion 310 abutting against the latching member 500, and a same effect can be achieved as well.

[0076] It would be noted, in order to prevent the user's fingers and other parts from being pinched by the supporting foot 300 and the sliding member 400 when the supporting foot 300 is turned into the sliding member 400, preferably, the safety seat 1 further includes a protective member 600, and the protective member 600 is, for example, an arc-shaped hollow casing having an arc surface 610, and is pivotally connected to the sliding member 400 and is arranged between the supporting foot 300 and the sliding member 400. Thus, when the supporting foot 300 is turned into the sliding member 400 in the clockwise direction, the protective member 6oo will be pivoted to a gap between the supporting foot 300 and the sliding member 400 along an inner edge of the sliding member 400 due to the action of gravity, so as to prevent the user's fingers and other parts from being pinched when protruding into the gap. Moreover, when the supporting foot 300 is turned out from the sliding member 400, an upper end of the supporting foot 300 (an end in respect to the supporting portion 310) will automatically push the protective member 600 back to the position shown in Figs. 8 and 9.

[0077] On the other hand, in this embodiment, the base too further includes a stopping portion 120, and the stopping portion 120 is, for example, a baffle plate and is arranged at the rear end of the base too in the longitudinal direction L, and a distance from the front end of the supporting foot 300 to the rear end of the base too is, for example, between 365 mm and 535 mm, moreover, when the supporting foot 300 is folded, a distance from the bottom of the base too to the top of the body 200 is, for example, between 715 mm and 752 mm, and a height of the base too is, for example, between 155 mm and 325 mm. with such sizes, the safety seat 1 is suitable for use in various passenger cars. On the other hand, when the safety seat 1 is in the folded state, one end of the supporting foot 300 close to the supporting portion 310 and the unlatching portion 320 will be blocked by the stopping portion 120 and will not be pivoted in respect to the base too, so that the safety seat 1 may be maintained in the folded state and the bottom of the base too is maintained flat.

[0078] A complete description of the operation process of the safety seat 1 will be given below. Please refer to Figs. 7 to 11 together, in which Fig. 11 is a schematic perspective view of the safety seat in Fig. 7 when the supporting foot is fully folded. Firstly, when the safety seat 1 is in the unfolded state, the positioning portion 420 at the rear end of the sliding member 400 in the longitudinal direction L is limited by the latching member 500, and thus maintained at a position protruding in respect to the base too. When the user wants to fold the safety seat 1, the supporting foot 300 can be turned into the sliding member 400. At this time, the unlatching portion 320 may abut against the latching member 500 such that it is deviated from the rear end of the sliding member 400 in the longitudinal direction L and will no longer be latched with the sliding member 400 to each other. At this time, the user can further slide the supporting foot 300 receiving the sliding member 400 into the accommodating space S along a direction opposite to the longitudinal direction L, until the limiting member 130 abuts against the front end of the sliding slot 412 in the longitudinal direction L, and at the same time, one end of the supporting foot 300 close to the supporting portion 310 is blocked by the stopping portion 120 and left in the accommodating space S, forming a state as shown in Fig. 11.

[0079] When the user wants to unfold the supporting foot 300 in respect to the base too again, it is only needed to slide the sliding member 400 in respect to the base too along the longitudinal direction L, and turn out the supporting foot 300 from the body portion 410. At this time, the latching member 500 is again pivoted to the rear end of the positioning portion 420 in the longitudinal direction L because the latching member 500 is no longer abutted against by the unlatching portion 320 and the body portion 410, such that the supporting foot 300 and the sliding member 400 are maintained in the position of the unfolded state.

[0080] Please refer to Figs. 12 and 13, in which Fig. 12 is a schematic rear view of a safety seat according to a second embodiment of the invention, and Fig. 13 is schematic sectional view of Fig. 12 along Y-Y section. The safety seat 1 in this embodiment is similar to the safety seat 1 in the first embodiment, and the main difference between them is that the latching members 500a in this embodiment are slidably disposed on the base too.

[0081] In detail, the latching members 500a in this embodimenthas, for example, two, and the two latching members 500a are respectively arranged on both of left and right sides of the sliding member 400. Furthermore, the safety seat 1 further includes resilient member for latching 510a, and the resilient member for latching 510a is, for example, linear spring and is arranged between the latching member 500a and the base too. When the supporting foot 300 is folded in respect to the sliding member 400, a part of the supporting foot 300 may abut against the latching members 500a such that the latching members 500a are respectively retracted toward both of left and right sides of the base too to positions shown by dotted lines in Fig. 12, and do not continue to block the sliding member 400. In addition, during the retracting process of the latching members 500a, the resilient member for latching 510a may be deformed at the same time and accumulate elastic force. Therefore, when the supporting foot 300 is turned out from the sliding member 400 again, the latching members 500a can be reset immediately and limit the sliding member 400 to an unfolded position.

[0082] Please refer to Fig. 14, which is schematic sectional view of a safety seat according to a third embodiment of the invention along Y-Y section. The safety seat 1 in this embodiment is similar to the safety seat 1 in the second embodiment, and the main difference between them is that the latching members 500b in this embodiment are pivotally connected to the base too, and pivoting direction of the latching member 500b is parallel to the bottom surface of the base too.

[0083] In detail, the latching member 500b in this embodiment is pivotally connected to the base too respectively by pivot 520b, such that the latching member 500b can rotate in respect to the base too. Furthermore, The safety seat 1 in this embodiment further includes resilient member for latching 510b, and the resilient member for latching 510b is, for example, torsion spring, which can be deformed when the latching members 500b are pivoted to the positions shown by the dotted lines in Fig. 14 and accumulate elasticity. With such arrangement, same effect as that of the safety seat 1 in the second embodiment can also be achieved.

[0084] Please refer to Figs. 15 to 18, in which Fig. 15 is a schematic bottom view of a safety seat according to a fourth embodiment of the invention, Fig. 16 is a schematic perspective view of internal components of the safety seat in Fig. 15, Fig. 17 is a schematic perspective view of another angle of Fig. 16, and Fig. 18 is a schematic perspective view of a stopping member being unlatched from a bracket in Fig. 17. The safety seat 1 in this embodiment is approximately as same as the safety seat 1 in the first embodiment, and the main difference between them is that the safety seat 1 in this embodiment further includes a positioning lock 800, and the base too further includes brackets 140, and a sliding member 400a is slidably disposed on the brackets 140.

[0085] In detail, in order to improve the convenience for the user to pull out and unfold the supporting foot 300 from the base too, the safety seat 1 in this embodiment limits the supporting foot 300 to the locked state by the positioning lock 800, and when the positioning lock 800 releases the locked state of the supporting foot 300, the supporting foot 300 can be automatically slid to the unlatched position by the sliding member 400a and be pivoted and unfolded to a use state. As shown in Figs. 15 and 16, the number of the bracket 140 in this embodiment is, for example, two, and the two brackets 140 are fixed on the base too, and the sliding member 400a can slide along extension portions of the brackets 140 close to the front end of the safety seat 1. Preferably, the brackets 140 and the sliding member 400a each is made of a material selected from metals, and in order to improve the support strength provided by the brackets 140 and the sliding member 400a when the supporting foot 300 is in use, the safety seat 1 further includes reinforcement member 150, and the reinforcement member 150 is, for example, extruded aluminum members cooperating the shapes of the brackets 140, and is arranged between the bracket 140 and the sliding member 400a, so as to prevent the supporting foot 300 from causing the sliding member 400a to wear the brackets 140 or fall off from the brackets 140 due to repeated use.

[0086] In addition, in order to achieve the automatic sliding function of the supporting foot 300 mentioned as above, the supporting foot 300 in this embodiment is pivotally connected on the sliding member 400a through a pivot 360, and the safety seat 1 further includes auxiliary resilient members 160, and each of the auxiliary resilient members 160 is, for example, a linear spring with one end connected to the base too and the other end is connected to the sliding member 400a, and extension direction of the auxiliary resilient member 160 is parallel to the extension direction of the bracket 140 (i.e., the longitudinal direction L). Thus, when the supporting foot 300 is locked by the positioning lock 800, the auxiliary resilient member 160 is in an extended state and accumulate elastic force, and when the positioning lock 800 unlocks the supporting foot 300, the auxiliary resilient member 160 brings the sliding member 400a to slide along the extending direction of the bracket 140 to the unfolded position by the accumulated elastic force, such that the supporting foot 300 is rotated in respect to the pivot 360 to an unfolded state by its own weight.

[0087] As shown in Fig. 17, preferably, a limiting pin 142 is arranged on the brackets 140, a sliding slot 412a is arranged on the sliding member 400a, and the limiting pin 142 is slidably disposed in sliding slot 412a. With such arrangement, the sliding stroke of the sliding member 400a can be restricted, so as to prevent the sliding member 400a from entirely sliding out of the brackets 140 due to the elastic force of the auxiliary resilient members 160. Furthermore, in order to prevent the sliding member 400a from sliding in again along the brackets 140 during use, preferably, the safety seat 1 further includes a stopping member 700, and the stopping member 700 is slidably disposed on the sliding member 400a and selectively abuts against the bracket 140.

[0088] Specifically, the safety seat 1 further includes a resilient member for stopping 710, and the resilient member for stopping 710 is, for example, a linear spring and is connected to the sliding member 400a and the stopping member 700. On the other hand, a limiting pin 430 is arranged on the sliding member 400a, a long hole 720 is formed on the stopping member 700, and the limiting pin 430 is slidably disposed in the long hole 720. Thus, when the sliding member 400a is brought by the auxiliary resilient members 160 so that the part on which the stopping member 700 is arranged slides out in respect to the bracket 140, the stopping member 700 may slide down by an elastic force of the resilient member for stopping 710, then abut against the bracket 140 and the front of an end E of the reinforcement members 150, so as to prevent the sliding member 400a from sliding in along the brackets 140 again. If the user wants to receive the supporting foot 300 and the sliding member 400a into the base 100, he only needs to push the stopping member 700 up along an unlatching direction R as shown in Fig. 18, such that the stopping member 700 is no longer abutted against the brackets 140 and the end E of the reinforcement members 150, and then the supporting foot 300 and the sliding member 400a can be pushed in along the brackets 140.

[0089] Please refer to Figs. 19 to 24, in which Fig. 19 is a schematic bottom view of a safety seat according to a fifth embodiment of the invention, Fig. 20 is a schematic perspective view of the positioning lock in Fig. 19, Figs. 21 and 23 are schematic sectional views of the safety seat in Fig. 19 along Z-Z section respectively in locked and unlocked states, and Figs. 22 and 24 are partial enlarged schematic views of Figs. 20 and 22, respectively. The safety seat 1 in this embodiment is similar to the safety seat 1 in the fourth embodiment, and the main difference between them that the positioning lock 800 in this embodiment includes a locking portion 810, and the positioning lock 800 and the supporting foot 300 are latched to each other by the locking portion 810, and the supporting foot 300 can be directly pivoted from a folded position to a use position.

[0090] As shown ion Figs. 20 to 24, the safety seat 1 further includes a positioning lock 800, and the positioning lock 800 is arranged on the base too and includes a locking portion 810, and a bottom end of the supporting foot 300 has a locked portion 350. In this embodiment, the locking portion 810 is, for example, a locking pin, and the locked portion 350 is a locked hole corresponding to the locking pin, but the invention is not limited to this. According to actual requirements, the locked hole may also be arranged on the positioning lock 800, and the locking pin may be arranged on the supporting foot 300, furthermore, the locking portion 810 and the locked portion 350 may be selectively latched to each other.

[0091] In detail, when the positioning lock 800 is in the locked position, the user can pivot the supporting foot 300 to the folded position along the pivot 360, such that the locking portion 810 and the locked portion 350 are latched to each other to lock the supporting foot 300. Preferably, at least one of the locking portion 810 and the locked portion 350 is formed with a guiding portion. In this embodiment, for example, the locking portion 810 has a guiding portion 812, and the guiding portion 812 is guiding inclined plane, moreover, the locking portion 810 and the locked portion 350 are abutted against and latched to each other through the guiding portion 812. When the supporting foot 300 is pushed by the user to the folded position, the upper end of the locked portion 350 may abut against the guiding portion 812 so as to pass over the locking portion 810 and then be latched with the locking portion 810. If the user wants to release the locked state of the supporting foot 300, he only needs to move the positioning lock 800 to the unlocked position along the direction opposite to the longitudinal direction L, such that the locking portion 810 is no longer latched with the locked portion 350, the supporting foot 300 can be unfolded in respect to the base too, and then the supporting foot 300 can be slid to the position of the use state through the sliding member 400a.

[0092] In addition, in order to let the user to surely know that the positioning lock 800 is currently in the locked position or the unlocked position, the positioning lock 800 in this embodiment can provide a touch feedback when the user performing switching between different positions. Please refer to Figs. 20 and 25 together, in which Fig. 25 is a partial enlarged schematic view of Fig. 19. As shown in Fig. 20, the positioning lock 800 further includes positioning protrusion 820, and the positioning protrusion 820 is, for example, an elastic body, and the base too further includes an accommodating seat 170, and notches 172 are formed on the accommodating seat 170, the positioning lock 800 is arranged in the accommodating seat 170, and the positioning protrusion 820 is selectively latched to the notches 172.

[0093] Specifically, the number of the notches 172 in this embodiment is, for example, four, and the four notches 172 are respectively formed on both sides of the accommodating seat 170. When the user wants to move the positioning lock 800 from the locked position to the unlocked position, or to move the positioning lock from the unlocked position to the locked position, the positioning protrusions 820 will abut against the wall surface of the accommodating seat 170, at this time, the user needs to strengthen force in moving, such that the positioning protrusion 820 goes over the wall surface and is latched to the other notch 172. With such arrangement, not only the positioning lock 800 will not be easily unlocked or locked accidentally due to external force interference, but also the user can know the current position of the positioning lock 800 through touch feedback during operation, thereby improving convenience in use.

[0094] Please refer to Figs. 26 to 28, in which Fig. 26 is a schematic perspective view of a safety seat according to a sixth embodiment of the invention, Fig. 27 is a schematic perspective view of the base and the body of the safety seat in Fig. 26, and Fig. 28 is a schematic perspective view of the supporting foot, the casing, and the auxiliary bracket of the safety seat in Fig. 26. The safety seat 1 in this embodiment is similar to the safety seat 1 in the fourth embodiment, and the main difference between them is that the supporting foot 300 in this embodiment may be detached in respect to the base too.

[0095] In detail, in order to provide flexibility for the user to detach the supporting foot 300 from the safety seat 1 when the supporting foot 300 is not in use, the base too in this embodiment and the supporting foot 300 may be selectively latched to each other. Please refer to Figs. 28 to 32 together, in which Fig. 29 is a partial enlarged schematic view of Fig. 28, Fig. 30 is a schematic right-side sectional view of the safety seat in Fig. 26, Fig. 31 is a partial enlarged schematic view of the safety seat in Fig. 30 when the auxiliary bracket is in a latched position, and Fig. 32 is a schematic view of the safety seat in Fig. 31 when the auxiliary bracket is unlatched from the base. Different from the safety seat 1 in the fourth embodiment, the safety seat 1 in this embodiment has no sliding member 400a, but includes a casing 400b and an auxiliary bracket 140a, and the casing 400b is arranged on an outer side of the base too, and the supporting foot 300 is pivotally connected to the casing 400b; on the other hand, the auxiliary bracket 140a is slidably disposed on the base too and connected to the casing 400b. Thus, the casing 400b and the supporting foot 300 pivotally connected to the casing 400b can be slidably disposed on the base too through the auxiliary bracket 140a.

[0096] In addition, the auxiliary bracket 140a includes an operating member for latching 144, and the operating member for latching 144 is, for example, a button, and the base too is formed with a latching hole 180 and an opening. And the auxiliary bracket 140a is inserted into the opening. When the user slides the supporting foot 300 together with the auxiliary bracket 140 to the use position, the operating member for latching 144 will be latched in the latching hole 180, so the supporting foot 300 can be fixed in the use position and cannot slide freely. Moreover, when the user does not need to use the supporting foot 300, he can press the operating member for latching 144 to separate it from the latching hole 180, and at the same time the auxiliaiy bracket 140a and the casing 400b are slided toward the opening at the front end of the base too. At this time, the auxiliaiy bracket 140a and the casing 400b can be completely separated from the base too. In other words, through the operating member for latching 144 selectively latched to the latching hole 180, the supporting foot 300 can be detached from the base too, providing the user with greater flexibility in use.

[0097] Please refer to Figs. 33 and 34, in which Fig. 33 is a schematic perspective view of the safety seat in Fig. 27 when a shielding member is moved to a shielding position, and Fig. 34 is a schematic view of internal components of the safety seat in Fig. 33. It would be noted, the safety seat 1 in this embodiment further includes a shielding member 190, and the shielding member 190 is pivotably connected to the base too and adjacent to the opening. For example, in this embodiment, the shielding member 190 is directly pivotally connected to the base too. After the user detaches the supporting foot 300 from the base too, in order to avoid defects on the appearance of the safety seat 1 due to exposure of the opening or prevent infants from accidentally inserting their fingers into the opening and being pinched, the user can pivot the shielding member 190 to a shielding position to make it cover the opening, so that the appearance integrity of the base too can be improved, and injuries to infants can be prevented. [0098] Please refer to Figs. 35 and 36, in which Fig. 35 is a schematic perspective view of internal components of the safety seat according to a seventh embodiment of the invention, and Fig. 36 is a schematic right-side sectional view of Fig. 35. The safety seat 1 in this embodiment is similar to the safety seat 1 in the first embodiment, and the main difference between them is that the safety seat 1 in this embodiment further includes a positioning portion 420a for locking the sliding member 400 and the supporting foot 300 in the unfolded position.

[0099] In detail, the positioning portion 420a in this embodiment is arranged on the sliding member 400 and can slide together with the sliding member 400 in respect to the base too. As shown in Fig. 36, the safety seat 1 further includes a resilient member for positioning 422, and the resilient member for positioning 422 is, for example, a spring and is arranged between the positioning portion 420a and the sliding member 400. Therefore, during sliding process of the sliding member 400, the positioning portion 420a is subjected to an elastic force of the resilient member for positioning 422 and abuts against a lower edge of an upper wall surface of the base too. When the sliding member 400 slides in respect to the base too to the unfolded position, a gap C is formed between the sliding member 400 and the base too, and the positioning portion 420a will bounce into the gap C due to the elastic force of the resilient member for positioning 422, and is latched in the gap C and abuts against the sliding member 400 and the base too at the same time, such that the sliding member 400 and the supporting foot 300 are locked in the unfolded position. However, in other possible embodiments, the positioning portion 420a may also be arranged on the casing 400b as in the sixth embodiment, or the positioning portion 420a may only abut against one of the sliding member 400 and the base too, or even the safety seat 1 does not include the resilient member for positioning 422, but instead uses an elastic material to make the positioning portion 420a to achieve a selective latching effect, which is not limited in the invention.

[00100] It would be noted, in this embodiment, the safety seat 1 further includes a resilient member for pivoting 424, and the resilient member for pivoting 424 is, for example, a torsion spring and is arranged between the supporting foot 300 and the sliding member 400. Thus, when the sliding member 400 slides in respect to the base 100 to the unfolded position, the supporting foot 300 will be automatically ejected from the sliding member 400 to the unfolded state by an elastic force of the resilient member for pivoting 424, which makes it more convenient for the user to use the safety seat 1.

[00101] Compared with the prior art, since the supporting foot 300 is slidably and pivotably connected to the base 100, when the safety seat 1 is not in use or it is not needed to use the supporting foot 300, and the supporting foot 300 can be pivoted and slidably folded in respect to the base 100, thereby achieving effects of improving flexibility of use, conforming to size-related specifications and reducing occupied volume.

[00102] The invention has been described above in conjunction with the best embodiment. However, the invention is by no means limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the invention.
