Problems solved by technology

However, in the seat energy-absorbing anti-whiplash system of this type of structure, a lower horizontal plate is provided at the rear lower part of the backrest. The large space in the middle and large areas leads to poor comfort; and the lumbar support is set in the backrest, which increases the structure of the turning mechanism, cable, rotating shaft, spring, bracket, etc., resulting in high cost and heavy weight of the seat.

Embodiment 1

[0025] Such as figure 1 As shown, the seat 1 includes a backrest 11, and both sides of the backrest 11 have support frames 12. The support frames 12 are made of metal materials. The anti-whiplash structure includes a spring 2 and a fixing groove 3 arranged on the support frame 12. The spring 2 is a serpentine spring 2, and the spring 2 is located on the same plane, and the spring 2 is located at the middle part of the backrest 11 of the seat 1. In this embodiment, the number of springs 2 is two, and the number of fixing grooves 3 is four. In actual production, the number of springs 2 can be one or three, and the number of fixing grooves 3 can be two or six. .

[0026] Such as figure 2 As shown, in this embodiment, the fixing groove 3 is in the shape of a strip, but in actual production, the fixing groove 3 may be in the shape of an arc. The fixing slot 3 includes a first fixing portion 31 at both ends and a second fixing portion 32 between the two first fixing portions 31 ...

Embodiment 2

[0035] The structure and principle of this embodiment are basically the same as that of Embodiment 1. The difference lies in that in this embodiment, the two inner sidewalls at the middle of the second fixing part 32 fit together in a closed shape, that is, the middle of the second fixing part 32 The distance between the two inner sidewalls is zero, and the second fixing portion 32 is divided into two symmetrically arranged parts.

Abstract

The invention provides an anti-whip structure for an automobile seat and belongs to the technical field of automobile safety. The problems of high cost and poor comfort of the existing anti-whip structure are solved. According to the anti-whip structure for the automobile seat, the seat comprises a backrest; supporting frames are arranged on the two sides of the interior of the backrest; the anti-whip structure for the automobile seat comprises a plurality of springs and a plurality of fixed grooves, wherein the plurality of fixed grooves are formed in the supporting frames; the fixed groovescomprise first fixed parts and second fixed parts, wherein the first fixed parts are positioned at the two ends, and the second fixed parts are positioned between the two first fixed parts; crushing parts are arranged between the first fixed parts and the second fixed parts; two ends of springs correspondingly penetrate into the two first fixed parts of the corresponding fixed grooves so that thesprings are fixed between the two supporting frames; and when acting forces on the springs in the front-back direction of the automobile exceed a set force, the two ends of the springs can enter intothe second fixed parts from the first fixed parts by crossing the crushing parts. The anti-whip structure for the automobile seat has the advantages of low cost and good comfort.

Description

technical field [0001] The invention belongs to the technical field of automobile safety and relates to an anti-whiplash structure of an automobile seat. Background technique [0002] With the vigorous development of the automobile industry, the number of automobiles continues to increase, and automobile collision accidents are also on the rise. The collision of a car will cause whipping injuries to the occupants. In a rear-end collision, the whiplash damage to the cervical spine is the most serious and the probability is the most serious. There is a certain gap between the headrest and the headrest. This gap causes the head movement to lag. This lag makes the occupant's neck lean back until it reaches the limit, and then the head is thrown forward by the cervical spine like a whip, which leads to cervical spine injury. whiplash damage. [0003] In response to the above problems, people have made various improvements, and some have applied for patents. For example, the Chi...
