Embodiment Construction

[0025] figure 1 Shown is a schematic view of a car seat according to a first embodiment of the present invention. The car seat is composed of a backrest 1 and a seat 2 , wherein the seat 2 includes a cushion 3 , a seat frame 4 and a cover 5 . The backrest 1 comprises a backrest frame 6 and a slat-shaped part 7 suspended between the backrest frames in the manner of a hammock, the slat-shaped part 7 having an upper end 7a and a lower end 7b.

[0026] On the one hand, through the hinge 10b installed on the lower end 6b of the back frame 6 and connected to the lower end 7b of the slat-shaped part 7, on the other hand, through the connection between the transverse support 14 installed on the back frame 6 and the slat-shaped part 7 The hinge-like parts 15 between the back faces 7c can realize the effect of a hammock. In addition, in order to form a sufficiently free hanging end 7a, a flexible connecting piece 10a is installed on the upper end 7a of the slat-shaped part 7 to connec...

Abstract

The present invention relates to a vehicle seat having a backrest (1) and a chair seat (2), wherein the backrest (1) comprises a backrest frame (6) and assemblage (7, 8, 15, 25, 26) arranged there between, so as to form an S-shape backrest (1 )which can deform forwards and backwards at the shoulder area (12) and the lumbar vertebral column area(11)respectively; wherein the assemblage (7, 8, 15, 25, 26) comprises a flexible batten element (7) extending along the lengthwise direction of the backrest frame (6), and the top end (7a) and the bottom end (7b) of the flexible batten element are flexiblely installed on the upper end (6a) and the lower end (6b) of the backrest frame (6); at least one hinge element (15, 25, 26) is arranged at the neck region and the head region (13) between the rear surface (7c) of the batten element (7) and the backrest frame (6), wherein the forward and backward parallel translation (23a) of the neck region and the head region (13 )of the backrest (1) can be achieved by the rotary motion of the hinge element.

Description

technical field [0001] The present invention relates to a car seat with a backrest and a seat, and more particularly to a car seat with an S-shaped backrest capable of deforming forwardly or backwardly in both the shoulder region and the lumbar spine region. Background technique [0002] Car seats with deformable backrests are typically fitted with adjustable lumbar support at a location corresponding to the lumbar spine region of the human body. The support member can be adjusted back and forth, so that through the convex deformation of the backrest in the lumbar spine area, different supports can be provided according to the size of the gap between the back of the human body and the backrest, thereby improving the comfort of riding. [0003] The deformation of the lumbar spine support member can be set in advance by people, and the deformation is maintained until it is adjusted again (such as adjusting by turning the handwheel). Such adjustments require the use of at leas...
