Description
Technical Field
The utility model relates to a passive safe air bag protection field of car especially relates to a passenger train roof air bag device.
Background
With the rapid development of the automobile industry and national economy, the automobile keeping quantity in China is ascending the top of the world. Passenger cars and buses become main transportation tools for highway passenger transportation in China, but the passenger cars have more passengers, larger mass and volume and higher mass centers, so compared with small and medium-sized cars, the passenger cars have poorer stability and can cause serious consequences of crowd injury once collision occurs. Airbags are an important passive measure to reduce injuries, which will reduce the injuries from secondary collisions in an accident.
To solve the above problems, many and varied airbag protection devices have appeared on the market. "a hatch door gasbag passenger train safety device that turns on one's side" (application number 201210424198.7) like utility model discloses a it detects the passenger train running state through the sensor to judge whether the passenger train takes place to turn on one's side. When the side turning of the passenger car is judged, the side-turning cabin door is opened through the ejection device, and meanwhile, the safety airbag arranged in the cabin door is opened, so that the energy generated by the side-turning collision is absorbed, and the deformation of the car body is reduced. Nevertheless this utility model though warp to the automobile body and play certain effect of alleviating, the passenger still can take place the motion in the car, causes secondary collision, and this utility model does not have the effect of alleviating to this kind of secondary collision.
