Problems solved by technology

[0004] After 20ms, the driver starts to move, but has not yet reached the airbag;
[0009] It can be seen from the above that the traditional airbag cannot adjust the airbag expansion speed and shape according to the vehicle speed and the driver's seat position
If the sitting posture is forward, the human body collides with the steering wheel of the car before the airbag is deployed, and hits the head violently when the airbag is deployed, which will reduce the protective effect of the airbag or cause the airbag to fail

Embodiment Construction

[0034] The following are specific embodiments of the present invention and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0035] An airbag with variable inflation speed for automobiles, including a controller, a sensor, a puller motor and a safety airbag, is characterized in that the sensor signals collected by the controller include a collision sensor, a vehicle speed sensor, a seat attitude sensor and a seat weight sensor;

[0036] The vehicle speed sensor and the collision sensor detect the initial time and speed of the collision, and input the detection signal to the controller, and the controller controls the opening speed of the airbag according to the vehicle speed signal and the collision signal;

[0037] The seat posture sensor and seat weight sensor detect the position of the occupant from the air bag, and send the position signal to the controller to control the opening speed of the air bag;...

Abstract

The invention relates to an air bag with variable expansion speed for an automobile, belonging to the technical field of automobile airbag, comprises a controller, a sensor, a brace motor and an air bag, wherein the air bag is internally provided with a plurality of braces, the brace motor is a multi-channel motor with turbine worm deceleration and locking, the output end of each channel is woundwith a brace, and the other end of the brace is fixed on the inner wall of the air bag inlet. The invention has the advantages that when the occupant sits close to the airbag, the stretching strip ofthe airbag is loose; When the speed is high, all the braces of the airbag are loose. The above technology can effectively protect the occupants under the changeable and complicated working conditions.

Description

technical field [0001] The invention relates to a safety airbag with variable inflation speed for automobiles, which belongs to the technical field of automobile safety. Background technique [0002] The opening speed and shape of traditional car airbag airbags are fixed. For example, the opening process of Audi’s airbags is as follows: [0003] 10ms after the vehicle collides, the airbag igniter detonates; [0004] After 20ms, the driver starts to move, but has not yet reached the airbag; [0005] After 40ms, the airbag has been fully deployed, the driver gradually moves forward, the seat belt is tightened, and part of the energy is absorbed; [0006] After 60ms, the driver has started to sink towards the airbag; [0007] 80ms The exhaust port of the airbag is opened to absorb the collision energy between the human body and the airbag; [0008] After 120ms, the driver moves forward to the maximum distance, and then returns to the seat. The air bag is deflated. [0009...
