When a collision airbag deployment, primarily prevents the passenger directly collides with the rear window and the surrounding rigid member.
1. The rear head airbags (curtain airbags) What
· In general, most of the front and rear head airbags are through type that only the front of the head only a few brands balloon. Usually mounted on the rear windshield, or both sides of the steel beam inside a B-pillar, the airbag identification.
· seat belts and air bags is a complete security system, it can be said airbags are secondary seat belt, so buckle up is a prerequisite.
· on and hit the balloon can not be foolproof, nor is it comfortable and soft feeling. It will still be the case even more serious injuries occur.
· Not every collision occurred balloon will pop up. Collision does not touch the air bag sensing points, or reach the standard value when the air bag is turned on, the balloon will not pop up.
· airbags sometimes do not necessarily play well with. When the child seat or the passenger deviate ride, starting airbag system not only would not achieve proper protection, but also may cause some harm to the crew. In addition, cars with very low vehicle speed issuedWhen students collision accident, the driver and passenger to wear seat belts, airbags deployed completely without protection. But if the time to deploy the airbag can cause unnecessary waste and may even aggravate collision damage caused by deployment of the airbag.
airbag warning lamp on the instrument · If the indicator airbags may fail, you will need to carry out checks and maintenance.
2 rear head airbags (air curtain) technical principle
The airbag consists of three parts: an airbag, and an inflator sensor systems.
When the sensor detects a vehicle collision, the inflator system can be quickly inflated in a time less than a tenth of one second, to produce harmless nitrogen gas or compressed nitrogen filled balloon release. So that the vehicle occupant from an impact due to the biasing force generated by the impact, after about one second, will shrink the balloon (balloon deflated hole), and therefore does not interfere with the action occupants.
