The technical solution of the invention is as follows:
an automobile safety airbag comprises an airbag and a gas generator, and is characterized in that: the gas generator is two and sets up in the inside left and right sides of air pocket, the air pocket includes ear stationary blade and air pocket bag piece, air pocket bag piece inboard and limit seam, ear stationary blade sews up the inboard intermediate position at air pocket bag piece, and folding back air pocket is flexible strip form, is dome shape after the air pocket expandes.
Further, an air bag wrapping sheet is arranged outside the air bag, and the air bag wrapping sheet is cylindrical and is sleeved in the air bag wrapping sheet after being folded and is wrapped by the air bag wrapping sheet.
Furthermore, the ear-shaped fixing piece and the air bag piece are respectively two, the inner sides of the two air bag pieces are lapped and sewn, and the air bag pieces are folded in half and the peripheries of the air bag pieces are sewn.
Further, the middle part of the air bag is sewn along an S-shaped stitch so as to control the thickness of the air bag.
According to the installation structure of the automobile safety air bag, the safety air bag is installed in the skin of the seat back along the edge of the seat back, and the skin is provided with the weakening line; connecting and fixing the gas generator and the framework of the seat at the gas generator mounting positions of the safety airbags on the two sides of the seat back; the ear-shaped fixing piece is connected and fixed with the top framework of the seat back at the mounting position of the ear-shaped fixing piece of the air bag of the safety air bag of the seat.
An automobile safety air bag is characterized in that: the airbag of the airbag is unfolded to be dome-shaped, the airbag is in a bendable strip shape after being folded, is arranged in the skin of the seat back along the edge of the seat back and is fixed on the framework of the seat back. When the automobile is in side collision or side rolling, the safety air bag is ignited, and the air bag of the safety air bag breaks through the weakening line of the seat back skin and is unfolded at the top of the head and two sides of the upper trunk of a driver or a passenger. The head, neck, shoulder, chest and rib of the driver or passenger are protected.
The invention has the beneficial effects that:
1. when the automobile has side collision and side rolling collision, the safety air bag on the seat of the driver or the passenger is detonated, and the air bag of the safety air bag breaks through the weakening line of the seat back skin and is unfolded at the top of the head and two sides of the upper trunk of the driver or the passenger. The head, neck, shoulder, chest and rib of the driver or passenger are protected.
2. The vehicle protection device has a protection function for a driver and passengers in a side collision of the vehicle, and simultaneously has a protection function for the driver and the passengers in a side rolling of the vehicle.
3. Can replace CAB curtain type safety air bags, SAB side air bags and Far-SAB Far-end side air bags, reduces the configuration types and the number of the automobile safety air bags and reduces the manufacturing cost of automobiles.
4. The problem of the unable installation of car CAB curtain formula gasbag of all-wing aircraft overall arrangement door is solved.
