SEAT
Document Type and Number:
WIPO Patent Application WO/2020/232839
Kind Code:
A1
Abstract:
A seat, comprising a seat frame (100) having a first seat frame side (110) and a second seat frame side (120) that are symmetrically arranged; a back frame (200), the lower part of which is connected to the seat frame (100), having a first back frame side (210) and a second back frame side (220) that are symmetrically arranged; a connecting base (300) connected to the lower part of the seat frame (100) and the lower part of the back frame (200), the connecting base (300), the lower part of the seat frame (100), and the lower part of the back frame (200) being connected together to form a kinematic chain mechanism (400); and a first flexible member (500), two ends of which are connected to the seat frame (100) and the back frame (200) respectively, being able to elastically deform and reset and rebound under the effect of an external force. Under the effect of the kinematic chain mechanism (400), when the back frame (200) is subjected to a backward acting force, the seat frame (100) moves backward and lifted, the first flexible member (500) deforms and an opening at a bend is expanded; when the backward acting force applied to the back frame (200) is gradually reduced, the seat frame (100) gradually moves forward and is lowered, and the first flexible member (500) gradually resets and rebounds until it returns to an initial state. The operation is simple and the structure is simple.
