Abstract
The present invention relates to an airbag deployment device for decreasing peak pressure of an airbag in which an inflation tube is provided to a tear seam of a cover and an inflation tube is connected to an inflator through a gas supply tube. When the inflator is operated, the tear seam is torn due to the inflation of inflation tube before the airbag is deployed toward the outside of the cover. Accordingly, when the airbag is deployed, the peak pressure is significantly decreased. As a result, even though a passenger collides with the airbag to be deployed, it is possible to obtain an advantage of decreasing the degree of injury.
Claims17
A device for decreasing peak pressure of an airbag, the apparatus comprising:
- an airbag;
- an airbag cover receiving the airbag therein to protect the airbag;
- a tear seam formed on the airbag cover and configured to be torn by pressure applied from the airbag;
- and
- a previously-pressing member displaced at the tear seam and configured to apply pressure to the tear seam prior to the airbag.
A passenger vehicle comprising the airbag deployment system as defined in claim 15.
