Seat energy-absorbing anti-whiplash system

Abstract

The invention discloses a vehicle seat energy-absorbing anti-whiplash system which is characterized in that: a lower transverse plate is arranged at the rear lower part of a seat; the two ends of the lower transverse plate are fixed on the two sides of the seat respectively; the lower side of a waist support of the seat is fixed above the lower transverse plate; multiple vertical creases are arranged at the middle part of the lower transverse plate; if the vehicle is collided from the rear side, the waist and hip of a driver exert a great thrust to the lower transverse plate, thus causing that the vertical creases of the lower transverse plate below the seat are partially expanded; and the kinetic energy of the driver is absorbed in the plastic deformation process. As the creases of the lower transverse plate are partially expanded by the driver after rear collision, a larger space is available for the head and body of the driver to move backwards at an approximately same speed, thereby reducing relative acceleration between the head and the body and realizing an anti-whiplash effect.

Description

technical field [0001] The invention relates to an energy-absorbing anti-whiplash system for a vehicle seat. Background technique [0002] The process of whiplash injury is: when the car is hit by the rear, the following typical actions will occur in rapid succession for the occupants in the car: the first step, due to the forward movement of the seat back relative to the back of the human body, the bow in the normal state The spine is pushed straight by the forward thrust from the seat back, and the curved and straightened spine drives the head of the human body to rise vertically; in the second step, when the seat pushes the occupant's torso forward, the unrestrained head moves forward. There is a tendency to fall behind under the action of inertia, which causes the neck to change and deform, taking an S shape for the first time and bending backwards. In the third step, the torso is restrained by the safety belt, and the head driven by the neck swings forward after hittin...

AI Technical Summary

Problems solved by technology

[0003] The invention application with the patent application number 201010191220.9 discloses an invention patent named "Anti-whiplash Device for Car Seats". The process is complicated and costly, so it is not suitable for promotion

[0004] The utility model patent with the patent number ZL201020669405.1 discloses a device called "anti-whiplash device".

The time is very short, and the patent uses a complex mechanism to achieve anti-whiplash, and the time from triggering to action of the mechanism will exceed the time of rear impact, so the slow response of the mechanical mechanism cannot play an anti-whiplash effect
