Abstract
The disclosed apparatus can control the cross section of at least one vent opening of an airbag module, through which gases can escape into the environment. The apparatus can include: at least one covering part for at least partially covering the at least one vent opening and an operating mechanism comprising a gas source and an inflatable element in fluid communication with the gas source. The inflatable element can be configured to produce a variation in the outlet cross section of the vent opening in cooperation with the covering part.
Claims35
An apparatus for controlling an outlet cross section of at least one vent opening of an airbag module, through which gas can escape from the airbag module, comprising:
- at least one covering part for at least partially covering the at least one vent opening;
- and
- an operating mechanism comprising a gas source and an inflatable element in fluid communication with the gas source,
- wherein the inflatable element is configured to produce a variation in the outlet cross section of the vent opening in cooperation with the covering part,
- wherein the covering part is formed by at least one flexible piece and forms a component of the inflatable element, and
- wherein the covering part is releasably fastened in a position in which the covering part at least partially covers the vent opening and is configured to lift off from the vent opening when the inflatable element fills with gas.
An airbag module for motor vehicles comprising:
- a gas bag for protecting a vehicle occupant;
- a gas generator for inflating the gas bag;
- a vent opening through which gas originating from the airbag module can escape;
- and
- an apparatus for controlling an outlet cross section of the vent opening comprising:
- at least one covering part for at least partially covering the at least one vent opening;
- and
- an operating mechanism comprising a gas source and an inflatable element in fluid communication with the gas source,
- wherein the inflatable element is configured to produce a variation in the outlet cross section of the vent opening in cooperation with the covering part,
- wherein the covering part is formed by at least one flexible piece and forms a component of the inflatable element, and
- wherein the covering part is releasably fastened in a position in which the covering part at least partially covers the vent opening and is configured to lift off from the vent opening when the inflatable element fills with gas.
