Definitions
- the present invention relates to a slide fastener that has a predetermined lateral pulling force and that breaks when a lateral pulling force that is equal to or greater than a tearing lateral pulling force is applied, and more particularly, an airbag inflating that inflates an airbag when an automobile collides.
- the present invention relates to a slide fastener that can be used for an opening.
- the side airbag device includes an inflator that generates inflation gas after an automobile collides and receives a large impact, and an airbag that is inflated and deployed by supplying gas from the inflator.
- the airbag In the airbag storage state before the side airbag device is activated, the airbag is folded in a predetermined procedure and stored in the seat back side portion of the automobile seat, and the side airbag device itself is a seat cover or the like. Covered.
- the surface of an automobile seat is covered with a seat cover such as fabric or leather for covering the cushion material of the seat, and the seat cover on the side of the seat back to which the side airbag device is attached is An inflating opening for inflating the airbag is formed.
- the bulge opening has been sutured with a fragile suture that is cut when pulled with a predetermined force.
- This side airbag device senses the impact when the automobile collides and receives a large impact, generates high-pressure gas from the inflator, introduces it into the airbag, and instantly inflates the airbag.
- the airbag When the airbag is inflated, an excessive pulling force is applied to the suture stitching the inflation opening, so that the suture is cut by this force and the closed inflation opening is opened. Then, the airbag bulges out from there.
