[0089] Figure 1A is the first embodiment of the invention with a zipper closure, figure 2 It is the zipper 100 of the first embodiment on the position of the vehicle seat 20 .

[0090] The zipper 100 comprises two longitudinal strips 102 , the inner longitudinal edges 101 of which are fitted with several engaging members 104 .

[0091] As is well known to those skilled in the art, the joining members 104 close the zipper and join the longitudinal straps 102 together by interlocking. The engagement member 104 is engaged within the first region 106 and the second region 107 when the zipper is closed. No joining member 104 is provided between the first and second regions, but a slit 110 is provided between the first and second regions. The slit 110 is located in the center of the zipper. In the center of the split there is a linker 115 where it links the two longitudinal straps together to prevent separation of the joining members. The ends 109 of the zipper 100 are fixed t...

Abstract

A zipper for an air bag cover, the zipper comprising first and second longitudinal strips secured to the edges of an opening of the air bag cover, and a linker together joining the two longitudinal strips. A row of engaging members is mounted on each longitudinal belt. The joint is sufficiently strong in the area of ​​the joined joint members, but the joint is easily detached from the ends of the area of ​​the joint members. The zipper also includes holding means that hold the longitudinal strips together at a predetermined position in the middle of the zipper. Under the action of the expansion force of the air bag, the retaining device will loosen or move. When the airbag is inflated, for example in the event of a crash, the retaining means allow the engagement members to open, thus opening the zipper and simultaneously allowing the airbag to inflate outside the airbag cover.

Description

technical field [0001] The present invention relates to a zipper, in particular to a zipper for closing an air bag cover. Background technique [0002] Cars often have air bags that act as safety devices in the event of a crash. The air bag is located at the front of the car, for example, in the middle part of the steering wheel. In the event of a collision, the airbags inflate as soon as the sensors detect the collision. This relieves the occupant from rushing forward from the seat. [0003] Side airbags, which inflate in the space between the seat and the door, cushion occupants from the impact of the side of the car, are becoming more common in cars, as are frontal airbags. The usual installation location for side air bags is the back of the car seat. In a crash, the air bag inflates and squeezes through an opening, such as a cutout, in the side of the seat. Open air bags inflate along the side of the car to protect the driver from collisions...
