Abstract
The invention discloses a back rest shape-adjustable seat, which is used to solve the problem that the waist and lower part of a user are suspended and cannot be supported by the back rest of the prior seat when the user leans back in the seat because the back rest of the seat is fixed in shape. The seat comprises a mat assembly, a back rest assembly and an adjusting mechanism, wherein the back rest assembly comprises a back rest framework and a back rest which comprises an upper back rest arranged on the back rest framework and a lower back rest capable of moving relative to the upper back rest; and the adjusting mechanism comprises a supporting element and a limit control device. One end of the supporting element supports the lower back rest and the other end is controlled and limited by the limit control device. When the seat is used, the lower back rest is driven by the supporting element to move relative to the upper back rest to change the angle to the upper back rest, so the effect of adjusting the shape of the back rest is achieved.
Description
Technical field:
