Abstract

The invention discloses a car seat backrest avoidance device and method. The safety device includes: a seat angle adjustment part, which includes a ratchet and a claw, one of which is installed on the backrest of the car seat, and the other is installed on the backrest of the car seat. For the seat of a car seat, when the backward pressure on the backrest exceeds the preset pressure, the ratchet and the claw can rotate relatively to adjust the angle of the backrest; the transparent detection part is located on the back of the windshield of the car, and the transparent detection part After being pierced, the transparent detection part detects and outputs a danger signal; the safety belt control part receives the danger signal, and controls the seat belt to be locked to drive the backrest and the corresponding occupants to lean back to avoid danger. The above-mentioned safety avoiding device and method can achieve the purpose of avoiding danger no matter whether the vehicle is rear-end collided or the windshield is pierced by a sharp object, and the avoidance is reliable without the intervention of human factors.

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...
