Airbag arrangement
First Claim
1. An airbag arrangement for a vehicle occupant restraint system, comprising:
- an inflatable airbag comprising at least one outflow opening through which gas can flow out of the airbag;
a stretchable element comprising a covering structure for adjustably covering a portion of the outflow opening, the covering structure being moved relative to the outflow opening when the stretchable element is stretched;
a fastener for fastening the stretchable element to the airbag so the stretchable element stretches when the airbag inflates and the covering structure moves relative to the outflow opening changing the size of the covered portion of the outflow opening; and
a receptacle connected to the airbag,wherein at least portions of the stretchable element pass through the receptacle,wherein the fastener is configured to release the stretchable element as a function of a control signal so the stress on the stretchable element is reduced and the covering structure moves relative to the outflow opening so the change in the size of the covered portion of the outflow opening is at least partially reversed.

Abstract
An airbag arrangement for a vehicle occupant restraint system includes an inflatable airbag having at least one outflow opening through which gas can flow out of the airbag. The airbag arrangement also includes a stretchable element including a covering structure for adjustably covering a portion of the outflow opening. The covering structure moves relative to the outflow opening when the stretchable element is stretched. The airbag arrangement also includes a fastener for fastening the stretchable element to the airbag so the stretchable element stretches when the airbag inflates and the covering structure moves relative to the outflow opening changing the size of the covered portion of the outflow opening.

25. An airbag arrangement for a vehicle occupant restraint system, comprising:
-
an inflatable airbag comprising at least one outflow opening through which gas can flow out of the airbag; a stretchable element comprising a covering structure for adjustably covering a portion of the outflow opening, the covering structure being moved relative to the outflow opening when the stretchable element is stretched; and a fastener for fastening the stretchable element to the airbag so the stretchable element stretches when the airbag inflates and the covering structure moves relative to the outflow opening changing the size of the covered portion of the outflow opening, wherein the fastener is configured to release the stretchable element as a function of a control signal so the stress on the stretchable element is reduced and the covering structure moves relative to the outflow opening so the change in the size of the covered portion of the outflow opening is at least partially reversed, wherein the stretchable element is moved out of an initial position when the airbag is inflated and toward the initial position again after the stretchable element is released.
