Abstract

The invention discloses an automotive safety seat backrest which comprises a backrest connecting seat. A backrest bracket is connected to the backrest connecting seat through an angle adjusting device, a swing frame is arranged in the middle of the front of the backrest bracket, and the lower end of the swing frame is hinged to the backrest bracket, a sliding frame is arranged in the backrest bracket, and multiple groups of tension springs are symmetrically arranged between the sliding frame and a bottom beam of the backrest bracket. A guide wheel is arranged in the middle of the upper end of the backrest bracket, a rotary shaft is arranged in the middle of the sliding frame and at the upper end of the swing frame respectively, and a sliding frame pull belt is arranged between the two rotary shafts. A safety belt connecting seat is arranged on the swing frame, a safety helmet connecting belt and a main safety belt are connected to the safety belt connecting seat through a long shaft, and the safety helmet connecting belt is not provided with a top-free safety helmet. The automotive safety seat backrest has the advantages that an inertia impact force of a passenger can be effectively buffered during automotive collision, the passenger is actively and effectively protected, an existing automotive safeguard device can be completely replaced, safety performance is high, and the automotive safety seat backrest is wide in application scope and can be used by adults and children.

Description

technical field [0001] The invention relates to an active protection device for automobile safety, in particular to a backrest of an automobile safety seat. Background technique [0002] At present, existing automobile safety protection devices are mainly divided into active protection and passive protection. Among them, active protection mainly refers to automobile seat belts, which can help occupants to fit the seat as much as possible when the car is collided, so as to avoid The occupant's body and head collide with the internal components of the vehicle for a second time. Passive protection mainly refers to automobile airbags, whose function is to inflate and eject the occupant's head to passively protect the occupant's head when the car is hit. [0003] Although seat belts and airbags can protect the occupants to a certain extent, their protective effect is very limited, especially the active protection of seat belts is insufficient to buffer the inertial impact force ...
