Embodiment Construction

[0048] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0049] The specific embodiment 1 of a kind of vehicle of the present invention comprises compartment, and seat is arranged in compartment, and the specific structure of seat is as follows Figure 1 to Figure 7 As shown, the seat includes a seat and a backrest 10. The backrest 10 is a backrest, and the backrest includes a backrest frame. The fixing frame 7 is fixedly connected with the back cover 1, and the lower end of the flexible part 2 is provided with a driving mechanism 3 to drive the flexible part to bend and deform to fit the passenger's back. An inflatable airbag 8 for supporting the flexible part 2 is also arranged between the flexible part 2 and the rear sealing plate 1, and the inflatable airbag 8 can shrink and expand to match different bending degrees of the flexible part.

[0050] The flexible part 2 includes a vertically arranged, elongat...

Abstract

The invention relates to a vehicle, a seat, a seat backrest and a backrest framework. The vehicle comprises the seat, the seat comprises a seat body and the backrest, and the backrest is in a back-abutting form and comprises the backrest framework; the backrest framework comprises a flexible part located in the middle, the flexible part is connected with a driving mechanism, and the driving mechanism is used for achieving pulling and pressing in the up-down direction and / or pushing and pulling in the front-rear direction, so that the flexible part is bent and deforms to change the curvature ofthe flexible part, and accordingly the backrest fits the back of a passenger; the rear side of the flexible part is provided with an air inflation airbag for supporting the flexible part. During theactual application process of the backrest, the flexible part mainly achieves a shape setting function on the curved face of the front side of the backrest, the air inflation airbag achieves a supporting function, bending and deformation of the flexible part are continuous, the curvature of the flexible part can be more accurately adjusted, and the flexible part better fits the curve of the back of the passenger, so that the passenger has higher comfort.

Description

technical field [0001] The invention relates to a vehicle, a seat, a seat back and a back frame. Background technique [0002] In some public places or public transport vehicles, the curved shape of the front side of the backrest of most seats is a set shape, which cannot be adjusted according to the user's personal situation, which causes the user to often feel uncomfortable when using the seat. Since the design of the backrest curve does not match the curve of the back, the waist or neck and shoulders are in a suspended state, resulting in poor comfort and even causing spinal diseases in the user. Especially in the means of transportation, for the passengers who need to ride for a long time, the above-mentioned problems are particularly prominent. [0003] In response to the above problems, someone has proposed a design for a seat with an adjustable backrest curve. For example, an authorized announcement number is CN102180110B, a Chinese patent titled a seat with an adjus...
