Abstract

The invention relates to the technical field of automobiles, in particular to an integrated airbag of a vehicle and a control method and system of the integrated airbag, and the integrated airbag of the vehicle comprises a gas generator, a head airbag and an upper body side airbag; the head air bag comprises a head abutting part and a neck abutting part; the head abutting part is used for abutting against the head of a passenger after being inflated, and the neck abutting part is used for abutting against the neck of the passenger after being inflated; the upper body side air bag abuts against the side face of the passenger body after being inflated, the head air bag and the upper body side air bag are both arranged on a vehicle seat, and the head air bag and the upper body side air bag are communicated with each other, so that the air generator can inflate the head air bag and the upper body side air bag at the same time; the head air bag and the upper body side air bag can be unfolded at the same time during collision so as to limit relative movement of the head and the trunk of a passenger, the far-end side face collision human body restraint protection function is enhanced, meanwhile, the rear collision head and neck protection function is met, and more reliable protection can be effectively provided for the passenger.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an integrated airbag of a vehicle and a control method and system for the integrated airbag. Background technique [0002] The airbag is a safety protection device that protects the occupant and reduces the injury of the occupant in a car collision accident. Taking the far-end side airbag as an example, the far-end side airbag can protect the occupant well in side collisions and has received widespread attention. The distal side airbags can be divided into thoracoabdominal (pelvis) side airbags and head-thorax-abdominal integrated side airbags according to the position of occupant protection. Chest and abdomen. [0003] The existing headrest airbag and the far-end side airbag are composed of a gas generator, an airbag assembly, a deflector, a wrapping sheet, a wire harness assembly, a label, etc., and the headrest airbag is installed inside the seat headrest. Pillow airbag...
