Vehicle seat preventing whiplash injury

Abstract

The invention provides a vehicle seat preventing whiplash injury and belongs to the technical field of vehicle safety. A stretch control unit is arranged in a headrest and is capable of responding before collision and driving a stretch protecting pillow to extend rapidly, and the stretch protecting pillow stops when contacting with the head immediately; during collision, the distance between the pillow and the head is shortened through the extension of the stretch protecting pillow, the horizontal shifting of the head and neck is reduced, and the backward whiplash effect of the head is reduced. A buffering energy absorption damping rebound unit is arranged between a base and the backrest, during collision, under the effect of inertia, the human back produces a backward stress on the backrest and performs deflection displacement between the base and the backrest, under the effect of buffering energy absorption, the deflection kinetic energy and deflection speed of the backrest are decreased, the backrest rebounds when being threw to the limit, the rebounding speed of the backrest is decreased under the damping effect, and the forward head whiplash effect is reduced accordingly.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, in particular to a vehicle seat capable of preventing whiplash injuries. Background technique [0002] Whiplash injury is a neck injury caused by the vehicle in front of the vehicle in front of it. When a rear-end collision occurs, because the collision will cause the vehicle in front to move forward rapidly, the torso will also move forward with the vehicle body, but the head and neck are relatively free, and the head will fall behind under the action of inertia, resulting in Horizontal displacement of the head and neck, resulting in whiplash. [0003] In order to prevent the occurrence of whiplash injury as much as possible, relevant technicians have designed many seats and seat headrests for preventing whiplash injury. Some of these seats and seat headrests are difficult to implement because of their complex structure. Some can only be used once due to self-destructive design, but ...

Problems solved by technology

When a rear-end collision occurs, because the collision will cause the vehicle in front to move forward rapidly, the torso will also move forward with the vehicle body, but the head and neck are relatively free, and the head will fall behind under the action of inertia, resulting in Horizontal displacement of the head and neck leading to whiplash

[0003] In order to prevent the occurrence of whiplash injury as much as possible, relevant technicians have designed many seats and seat headrests for preventing whiplash injury. Some of these seats and seat headrests are difficult to implement because of their complex structure. Some can only be used once due to self-destructive design, but cannot be reused, and some have poor protection ability due to the lag of response action, so the actual application effect is not very ideal
