The actuation plate 50 is generally fixed to the base plate 31 of the lid 30 in a force- locked manner or in a form-locked manner or in a force-locked and form-locked manner. In particular, the abutment portion 52 can be fixed to the base plate 31 by an adhesive so that in this case the abutment portion 52 is fixed to the base plate 31 in a force-locked manner.

Figures 3 and 4 shows a further embodiment of the actuation device 5 with an actuation plate 50 extending over the complete front surface 31a of the base plate 31 of the lid 30. In this embodiment, the actuation portion 51 lies at least partially within the opening 38. The abutment portion 52 of the actuation plate 50 covers the base plate 31. In this regard, the abutment portion 52 can comprise edge folding sections 52a, 52b, which covers the lower edge surface 36a and the upper edge surface 37a, respectively. According to the embodiment of the actuation device 5 shown in figures 3 and 4, there is no edge folding section provided at the lateral edge portions 33 or 34, however this can be the case in a variant of this embodiment. Therefore, the actuation plate 50 can be realized as decoration layer.

The actuation portion 51 has a first surface 51a which extends along the first surface 31 a of the base plate 31 and which is part of a first surface 30a of the lid 30. Further, the actuation portion 51 has a second surface 51 b which extends along the second surface 31 b of the base plate 31 and which is part of a second surface 30b of the lid 30. Therefore, the first surface 51a of the actuation portion 51 faces the first side S1 and the second surface 51 b of the actuation portion 51 faces the second side S2.

According to one embodiment of the actuation device 5 the actuation portion 51 lies at least partially within the opening 38 when viewed from the fist side S1. According to an embodiment of the actuation plate 50, the actuation portion 51 extends so far into the opening 38 when viewed from the first side S1 that the second surface 51 b of the actuation portion 51 and the second surface 31 b of the base plate 31 form a continuous surface. Alternatively, the actuation portion 51 can be formed such that the second surface 51 b of the actuation portion 51 lies at a position of at least 50% of the depth d38 of the opening 38, wherein the depth d38 extends in the local lid thickness direction L-T from a respectively selected point on the first surface 31a.

The actuation portion 51 can be formed such that it comprises on its second surface 51b indentations in order to facilitate the bulge deformation of the actuation portion 51. As an example, the embodiment of figure 4 is shown with four

indentations 51-1 , 51-2, 51-3, 51-4 and the embodiment of figures 8 and 9 is shown with five indentations 351-1 , 351-2, 351-3, 351-4, 351-5. Particularly, such indentations can be formed as grooves. Such grooves can particularly extend parallel to each other in a regular manner when viewed across their respective longitudinal direction. The indentations can be formed such that they have a rectangular cross-section when viewed in the direction of the extension of the respective groove. Alternatively, this cross-section can for example be of circular shape.

The abutment portion 52 can be fixed to the base plate 31 of the lid 30 by an adhesive so that the abutment portion 52 is fixed to the base plate 31 in a force-locked manner. Alternatively or in addition to this arrangement, the abutment portion 52. can be fixed to the base plate 31 in a form-locked manner. In this regard, the edge folding sections 52a, 52b can be formed such that the edge folding sections 52a, 52b grip an end section of the base plate 31 at a respective edge surface, for example the edge surfaces 52a and 52b, respectively.

According to another embodiment of the actuation plate which is shown in figure 6 with reference numeral 150, the actuation plate 150 is designed such that the abutment portion 52 is lying on the rear side 31 b of the base plate 31 of the lid 30. According to one variant of the embodiment, the actuation plate 50 with the cross-section shown in figure 6 comprises one abutment portion 152 which encircles the actuation portion 151.

In the embodiments of the actuation plate 50, 150, the actuation plate 50, 150 can be produced as one piece. Preferably, the material of the actuation plate 50, 150 consists of an elastomer. The actuation portion 51 , 151 of the actuation plate 50, 150 is deformable such that it can be bulged out from a first state into an actuation state when an external actuation force FA is exerted on the actuation portion 51 , 151 in an actuation direction DA. The actuation direction DA runs across the area in which the opening 38 extends. The opening 38 can particularly be formed as an opening which is defined by an at least partially encircling inner edge portion 39 of the actuation portion 51 , 151.

The actuation plate 150 is designed such that the same and in particular the middle section 153 which lies between two opposing sections of the cavity 155 can be deformed in the case that an external actuation force FA is exerted on the middle section 153 for example by a finger of a user of the actuation device along the lid thickness direction L-T. As an example, an actuation deformation of the middle section 153 upon the exertion of the external actuation force FA is shown in figure 6 with dashed lines A. Thereby the first surface 151a of the actuation portion 151 assumes a form with a maximum displacement A151a. Accordingly, the second surface 151 b of the actuation portion 151 assumes a form with a maximum

displacement A151b. In particular, the actuation plate 150 is made of a material with a compressibility which does not result in a relevant change in thickness d153 when the force FA is exerted in a pre-determined manner for normal use of the actuation device according to the invention. Therefore, normally the maximum displacement A151a has the same amount than the maximum displacement A151b.

According to an aspect of the invention, the actuation device 5 with the support device or the cover device 3, the actuation plate 50, 150 and optionally a transmission device 6 is provided for transmitting a movement resulting from the bulge of the actuation portion 51 , 151 in the actuation direction DA to an input component of an adjustment device 7 such that the input component performs an input movement. The adjustment device 7 is configured such that it performs a movement of a position member due to the input movement of the input component.

The cover device 3 comprises the lid and an actuation plate 350 which can be realized according to one of the embodiments described herein, as is shown in figures 8 and 9 in an exemplary manner. An elastic strip 360 is mounted on the rear surface 31b of the base plate 31 or of the lid 30 by a mounting device 361 which fixes a first end 360a of the elastic strip 360 to the lid 30. The elastic strip 360 can in particular have an elongated form as is shown in figure 7. A second end section 360b is guided by a guiding device 362 in a translatory manner such that the second end section 360b moves, as shown in figure 7 for example in the direction L-W, when the actuation plate 350 is deformed in the actuation direction DA.

According to this embodiment of the actuation system, the actuation system comprises a mounting device 361 which is disposed at the rear surface 31 b of the base plate 31, a guiding device 362 which is disposed at the rear surface 31 b of the base plate 31 and an elastic strip 360 which is fixed at a first end section 360a by the mounting device 361 to the base plate 31 and which is at a second end section 360b guided by a guiding device 362 in a translatory manner such that the second end section 360b moves, when the actuation plate 350 is deformed in the actuation direction DA, wherein the adjustment device 7 is realized such that due to the input movement of the input component an output movement of the second end section 360b the latch component is moved from the latching state to the unlatching state or vice versa.

The elastic strip 360 can be made of or can consist of a metal for example a spring steel.

The transmission device 8 which comprises the above-mentioned elastic strip 360, the mounting device 361 and the guiding device 362, is coupled to an adjustment device 7. The adjustment device 7 is coupled to the latching mechanism 9.

The adjustment device 7 according to the embodiment of figure 7 to 1 comprises a first lever 371 , which is pivotally coupled to the lid 30 by a pivotal joint 372 so that the pivotal joint 372 provides a first lever arm 373 and a second lever arm 374 of the first lever 371. The pivotal joint 372 is realized such that the first lever 371 can rotate along a plane which extends in the planar extension of the rear surface of the lid 30. A fist end 37 a of the first lever 371 is coupled to the second end section 360b off the elastic strip 360. At its second end section 371 b the first lever 371 is pivotally coupled with a second lever 375 by a pivotal joint 374. The second lever 375 is pivotally coupled to the lid 30 by a pivotal joint 376 so that the pivotal joint 376 provides a first lever arm 377 and a second lever arm 378 of the second lever 375. The first end section 375a of the second lever 375 is pivotally coupled to the first lever 371 and a second end section 375b of the second lever 375 is pivotally coupled to the first lever 371. The second end section 375b is pivotally coupled to a first one of the latch components 91 , 92 of the latching mechanism 9. Further, the first end section 375b of the first lever 371 is pivotally coupled to the other one of the latch components 91 , 92 of the latching mechanism 9.

With this embodiment, a translatory movement of the second end section 360b of the elastic strip 360, which is shown by the arrow DA1 and which is caused by an actuation movement in the actuation direction DA of the actuation plate 350, causes swivel movement of the lever arms 373 and 374 and of the lever arms 377 and 378. These swivel movements cause a movement of the latch components 91 , 92 from a latching state to a release state. The elastic strip 360 is biased in a neutral state as shown in figures 8 and 9 so that by this biasing the second end section 360b of the elastic strip 360 is moved in an opposite direction as the arrow DA1 shows so that the latch components 91 , 92 are moved from a release state to a latching state in an analogous manner.

In a variant of this arrangement, one or several of the coupling levers 381 and 382 and 383 can additionally be provided:

The coupling lever 381 is coupled by a pivotal joint 381a to the end section 371b of the lever 371 and by a pivotal joint 381 b to the latch component 91 , wherein pivotal joint 374 is disposed between the pivotal joint 381a and the pivotal joint 372. Thereby it is possible that a guide device for defining the movement of the latch component 91 is possible which allows only a translatory movement of the latch component 91.

The coupling lever 382 is coupled by a pivotal joint 382a to the second end section 360b of the elastic strip 360 and by a pivotal joint 382b to the lever arm 373. Thereby the coupling between the second end section 360b and the coupling lever 382 is such that the lever arm 373 is coupled to the second end section 360b of the elastic strip 360 which can only move in a translatory manner due to the guiding device 362.

The coupling lever 383 is coupled by a pivotal joint 383a to an end section of the lever 378 and by a pivotal joint 383b to the latch component 92. Thereby it is possible that a guide device for defining the movement of the latch component 92 is possible which allows only a translatory movement of the latch component 92.

The pivotal joints for coupling the respective levers of the arrangement of levers shown in figure 10 and variants thereof can be realized such that the levers move themselves according to their respective functions in along the XL-YL-Plane.

On or more of the pivotal joints 381a, 381b, 382a, 382b, 383a, 383b can be realized as structural joints as shown in figure 1 for pivotal joint 381a.
