Automobile seat backrest backward tilting risk avoiding device and method

Abstract

The invention discloses an automobile seat backrest backward tilting risk avoiding device and a risk avoiding method. The risk avoiding device comprises a seat angle adjusting part, a transparent detection part and a safety belt control part, wherein the seat angle adjusting part includes a ratchet wheel and a clamping jaw, one is installed on a backrest of an automobile seat, the other one isinstalled on a seat of the automobile seat, and after backward pressure borne by the backrest exceeds preset pressure, the ratchet wheel and the clamping jaw can relatively rotate to adjust the angleof the backrest; the transparent detection part is arranged on a back surface of a windshield of the automobile, and after the transparent detection part is pierced, the transparent detection part detects and outputs a danger signal; and the safety belt control part receives the danger signal and makes the safety belt be locked so as to drive the backrest and the corresponding passenger to tilt backwards to avoid danger. According to the risk avoiding device and the risk avoiding method, a risk avoiding purpose can be achieved no matter whether rear-end collision happens to the automobile or the windshield is pierced by a sharp object, human factor intervention is not needed, and avoiding is reliable.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automotive seat backrest avoidance device and method. Background technique [0002] When the car encounters an emergency and dangerous situation, such as foreign objects penetrating through the windshield, it will endanger the life of the driver. The driver needs to have an escape space, but the space in the cab is limited. Even if there is an escape space, they may react Not fast enough to avoid. [0003] In view of the above situation, a relatively effective method is to use the device in the cockpit to make the driver avoid the dangerous area quickly. [0004] One of the schemes adopted at present is to use a detonator. When the vehicle collides, the detonator detonates and pushes the car seat to move backward. personnel; [0005] The second option is that when the vehicle collides with the A-pillar from the rear, the vehicle will automatically turn on the seat reclinin...
