Abstract

The invention provides a vehicle seat with an energy absorbing structure. The vehicle seat comprises a cushion side plate and an angle adjuster lower connecting plate, and an impacting groove is formed in the angle adjuster lower connecting plate and comprises a straight groove part and a round groove part which are communicated vertically. The vehicle seat further comprises an energy absorbing sheet, a first nut and a step bolt, wherein the energy absorbing sheet comprise an annular part, a positioning part and an impact breakage part connected between the annular part and the positioning part, the first nut is fixed to the cushion side plate, the step bolt comprises a head, a step part and a double-screw bolt which are all sequentially connected coaxially, and the double-screw bolt sequentially penetrates through the round groove part and the annular part and is in threaded connection with the first nut so that the step part can penetrate through the round groove part and can be matched with the energy absorbing sheet in a pressed mode. The vehicle seat is simple in structure, convenient to install and capable of absorbing energy in a washboarding mode in the collision process so that the rebounding speed of the head of a human body in the collision process of an automobile can be reduced, safety of a passenger is protected, and the grading level of the automobile is improved.

Description

technical field [0001] The invention relates to a vehicle seat, in particular to a vehicle seat with an energy-absorbing structure. Background technique [0002] In the process of driving a car, once a rear-end collision occurs, it is likely to cause whiplash injuries to the driver and occupant in the collided vehicle. Whiplash injury refers to the fact that under the joint action of collision acceleration and head inertial force, the neck will produce a whip-like whipping action. After the accident, the injured will feel different degrees of discomfort in the neck. This kind of injury is not fatal, but the recovery process after the injury is very complicated and lengthy, and some even cause permanent injuries that cannot be cured. In order to reduce injuries, automobile manufacturers have begun to develop car seats that can absorb impact energy. For example, patents CN103249595A, CN1640714A and US20100096892A1 respectively provide a car seat that can absorb impact energy....
