An airbag device includes an airbag, an airbag case that is made from metal and includes a base wall and a tubular wall, and an airbag cover that is made from synthetic resin and includes a covering wall and a joint wall. The case and cover are coupled together by insertion of hooks of the tubular wall of the case into joint holes of the joint wall of the cover. An approximation-limiting region suppresses the cover as coupled with the case from moving further towards the base wall of the case, and a separation-limiting region suppresses the cover as coupled with the case from moving further away from the base wall of the case. The approximation-limiting region includes an abutment region and a receiving region engageable with the abutment region. The separation-limiting region includes a retaining hole and a projection engageable with an inner surface of the retaining hole.

A knee airbag for vehicles is provided. The knee airbag includes a lower crash pad that has a panel shape to block a steering column to prevent exposure of the steering column to an indoor space of a vehicle, and includes a housing unit having recesses dented toward the steering column such that the housing unit is spaced apart from the steering column by a designated distance. An airbag module of the knee airbag includes an inflator and a cushion and contained in the housing unit of the lower crash pad to deploy the cushion toward a driver's knee outside the lower crash pad when the cushion is deployed by explosion of the inflator.

An airbag device includes an airbag, an inflator and a retainer. The retainer includes a generally tubular holding section for holding the inflator therein and mounting means which protrudes out of the holding section in a direction generally perpendicular to an axis of the inflator to be mounted on a vehicle body member in order to mount the airbag and the inflator on the vehicle body member. The holding section includes an elastically deformable support region which has been elastically deformed and brought into abutment against an outer circumference of the inflator when the inflator was inserted into the holding section, and supports the inflator in the elastically deformed state at an inner side of the holding section, and a supporting projection which has higher rigidity than the elastically deformable support region and abuts against the outer circumference of the inflator at the inner side of the holding section.

A knee airbag unit (10) of a vehicle occupant restraint system of a motor vehicle is described. The knee airbag unit (10) comprises an airbag module (12), which has a module holder (14), a gas generator (16) and a flexible, non-inherently rigid module housing (18) that at least partially surrounds the gas generator (16) and the airbag in the untriggered state, wherein the gas generator (16), the airbag and the flexible module housing (18) are fastened to the module holder (14). Also provided is a cover (20) forming a module covering and defining an outer side in the installed state of the knee airbag unit (10), which is connected to the airbag module (12). Furthermore, there is an edge-side means (26) securing the cover (20) against lowering, originating from the module holder (14).

A housing for a knee airbag module includes an enclosure structured to receive a knee airbag module therein, and a door rotatably coupled to the enclosure. A first securement element mounting hole is formed in the door at a location in the door structured to reside adjacent an outboard edge and a rearmost edge of the door when the door is in an open condition.

Airbag cushions and related assemblies configured to protect the lower extremities of a driver by deploying about the contours of a steering column shroud. In some embodiments, the assembly may comprise an inflatable cushion configured to be deployed adjacent to a vehicle steering column to provide protection to a driver's lower extremities during an impact event. The cushion may comprise a primary inflation chamber, a first supplemental inflation chamber fluidly coupled with the primary inflation chamber and configured to deploy on a left side of the vehicle steering column adjacent to the driver's left lower extremity, and a second supplemental inflation chamber fluidly coupled with the primary inflation chamber and configured to deploy on a right side of the vehicle steering column adjacent to the driver's right lower extremity.

An instrument panel assembly includes a support beam and an exterior panel. The instrument panel assembly includes an energy absorbing device between the support beam and the exterior panel and having a variable crush resistance based on a temperature of the energy absorbing device. The instrument panel assembly includes a heater operatively coupled to the energy absorbing device.

A vehicle occupant restraint system comprises an airbag module (12) which includes an airbag (16) as well as an inflator (18) which upon activation supplies filling gas for the airbag (16). The airbag (16) is folded prior to activation into an airbag package (14) so that a main package (48) which contains a restraint part (52) of the airbag (16) constituting a major part of the airbag volume as well as a connecting portion (50) is formed which comprises a neck (54) of the airbag (16) connecting the restraint part (52) to the inflator (18), wherein the restraint part (52) is folded differently from the neck (54).

A case for housing an inflator includes a protruding region for storing a connector of a wire harness which is connected to an inflator body. A body of the wire harness extends from the connector in a direction orthogonal to an axial direction of the inflator body. The protruding region protrudes from a circumferential wall of the case partially. The protruding region includes a stopper wall that is opposed to the connector as stored in the case in the axial direction of the inflator, and a pair of limiting walls that are engageable with the wire harness by the leading ends and thus limit an angle range with respect to the inflator body within which the wire harness is rotatable. The limiting walls each extend from the stopper wall and are disposed on both sides of the connector in the direction orthogonal to the axial direction of the inflator.

An instrument panel assembly includes an instrument panel. The instrument panel assembly includes an airbag having an inboard chamber and an outboard chamber. A panel separates the inboard chamber and the outboard chamber. A diffuser is in fluid communication with both the inboard chamber and the outboard chamber. A releasable vent is between the diffuser and one of the inboard chamber and the outboard chamber. An inflator is in fluid communication with the diffuser.
