Embodiment Construction

[0017] see figure 1 , figure 2 with image 3 As shown, in this embodiment, a groove 2 is provided between both sides of the seat back 1 and the side 3 of the seat, and the groove 2 separates the seat back 1 from the side 3 of the seat. The groove 2 is provided with a force-bearing expansion structure 4, such as Figure 4 with Figure 5 As shown, the stressed unfolding structure 4 is made of a flexible cloth folded into a V shape, the V-shaped flexible cloth is plugged in the groove 2, and the two sides of the V-shaped flexible cloth are respectively connected to the seat back 1 and the seat. The sides 3 are connected together.

[0018] For the beauty of the seat, the grooves 2 on both sides are covered with an elastic fabric 5, and the two sides of the elastic fabric 5 are sewn together with the seat back 1 and the side edge 3 of the seat.

[0019] The backs of the two stress-expanded structures 4 are connected together with two strips 6, such as Figure 4 with Figure...

Abstract

The invention discloses an automotive seat back capable of preventing lashing. Grooves are formed between two sides of the seat back and the side edges of a seat and separate the seat back from the side edges of the seat; stressed unfolding structures are arranged in the grooves and consist of flexible cloth folded in a V shape, the V-shaped flexible cloth is plugged into the grooves, and two side edges of the V-shaped flexible cloth are connected with the seat back and the side edge of the seat respectively. During low-speed rear collision, the seat back moves backwards, the stressed unfolding structures are unfolded, the back of a passenger is fully sunken into the seat back, and the head and the body of the passenger move backwards in the approximately same speed, so the relative acceleration of the head and the body is reduced, and a function of preventing lashing is realized; the automotive seat back is simple in structure and low in cost when the automotive seat back prevents lashing.

Description

technical field [0001] The invention relates to a car seat, in particular to a whiplash-proof car seat backrest. Background technique [0002] The seat anti-whiplash systems currently in use are mainly divided into two categories: 1. The active headrest realized by the mechanism, and the headrest and the lumbar support experiment are linked through the mechanism to realize the protective effect on the driver during a low-speed rear collision ; 2. Active backrest, adding mechanisms and springs to the backrest frame, in the event of a rear impact, the seat backrest can be rotated around a certain axis, and the headrest is closer to the person's head during the rotation process to protect the driver . [0003] The above seat anti-whiplash system has complex structure and high cost. Contents of the invention [0004] The object of the present invention is to provide a novel whiplash-proof car seat back. [0005] In the present invention, a groove is provided between the two...
