A gas bag arrangement for a vehicle occupant restraint system is provided. The gas bag arrangement comprises a gas bag inflatable by a gas generator to protect a vehicle occupant, whose envelope defines an interior space of the gas bag that can be filled with gas, a vent opening through which gas can flow out of the gas bag, and a device for controlling the outlet cross-section of the vent opening, which comprises at least one covering part with which the vent opening can be covered, in order to at least partly close the same, and which furthermore comprises an actuating mechanism which interacts with the covering part, in order to vary the outlet cross-section of the vent opening. The actuating mechanism includes an additional gas source and an element different from the gas bag and inflatable by means of the gas source.

Gas bag arrangement with a device for controlling an outlet cross-section of a vent opening

An airbag module for a motor vehicle is provided. The airbag module comprising a gas bag, which is inflatable by means of a gas generator for the protection of a person, and a vent opening through which gas originating from the airbag module can escape, and a device for controlling the outlet cross-section of the vent opening, which comprises at least one covering member with which the vent opening can be covered, in order to at least partly close the same, and which furthermore comprises an actuating mechanism which cooperates with the covering member, in order to vary the outlet cross-section of the vent opening. The actuating mechanism includes a gas source and an element inflatable by means of the gas source, which during inflation cooperates with the covering member such that it effects a change in the outlet cross-section of the vent opening.

Airbag module for a motor vehicle

A method for folding an airbag for an airbag module in which the airbag is disposed on a support is provided. At least one piling element for folding the airbag is provided next to the exterior edge of the airbag disposed on the support. The airbag is folded together using the at least one piling element in that the piling element is moved along the support in the direction toward the interior of the airbag disposed on the support. A retainer protrudes from the at least one piling element and moving together with the piling element during the movement thereof and reaching over or under an edge area of the airbag. The at least one retainer acts on an edge area of the airbag in such a way that an undercut is formed in the airbag through the effect of the retainer.

Method and device for folding an airbag for an airbag module

An airbag device for a vehicle, including an airbag package, a receptacle, and a flexible protective covering for the airbag. The flexible protective covering includes at least two flexible, sheet-like protective elements secured to the receptacle. The flexible, sheet-like protective elements are connected to one another via at least one separable tearing line. The flexible, sheet-like protective elements flank the airbag during initial inflation and expansion of the airbag. A flexible guide layer is arranged between the protective covering and the airbag package. The flexible guide layer is permanently connected to a first of the sheet-like protective elements, such that the first sheet-like protective element, together with the guide layer, forms a composite layer flanking the airbag during inflation.
