Energy absorber for automotive seats

Abstract

The invention provides an energy absorber for automotive seats, which belongs to the field of automobiles. The energy absorber solves the problem that the necks of passengers of the conventional automobile are hurt easily when the conventional automobile encounters a rear-end accident. The energy absorber for automotive seats is fixed on an automobile seat which comprises a seat board and a backrest; a sliding rail framework is arranged under one side of the seat board; and the backrest is hinged on the corresponding sliding rail framework by a backrest framework connected with the backrest. The device comprises an energy absorbing part made of a metal material, wherein the energy absorbing part is connected with the backrest framework and the sliding rail framework respectively; and the mechanical strength of the energy absorbing part is smaller than those of the backrest framework and the sliding rail framework. Once an accident happens, the energy absorbing part deforms to absorb kinetic energy as the back of a passenger presses the backrest under the action of inertia and makes the backrest rotate backward; and thus, the backward rotation speeds of the backrest framework and the backrest are reduced, and the backrest reliably supports and gently moves back the neck of the passenger to effectively protect the neck of the passenger.

Description

technical field [0001] The invention relates to a car seat, in particular to an energy absorbing device of the car seat, and belongs to the field of cars. Background technique [0002] With the rapid development of the automobile industry and the improvement of people's living standards, the number of private cars is increasing, which leads to an increasing incidence of traffic accidents, which greatly threatens the health and lives of car owners and passengers. We On the one hand, the driver is required to master proficient driving skills to avoid accidents. On the other hand, once an accident occurs, we also require the car to be equipped with some corresponding safety devices to reduce the damage to the occupants. The safety devices installed on existing cars mainly include seat belts, door locks, electronic stability control system ESC, front airbags, energy-absorbing steering columns, side airbags and side air curtains, tires, door anti-collision beams and collision buf...
