A knee airbag module for a motor vehicle. The airbag module has a housing which is preferably composed of plastic and has a housing base () and a wall extending from the housing base (), forming an outlet opening. A receptacle is provided in a first wall section. An airbag is folded into the housing, an air generator () which has outflow openings located within the airbag, and a covering element which closes the outlet opening. This covering element has a main section () which lies substantially in one plane, at least one first end section () accommodated in the at least one receptacle, and a second end section () situated opposite the first end section (), extends out of the plane of the main section () and is connected to the housing (). The covering element () is produced from a blank.

Airbag module and vehicle

An airbag housing with a receiving space for a gas generator and an airbag, wherein the receiving space is confined at least by a bottom, side walls, and end walls connecting the side walls, and wherein a fastening section projects from at least one of the walls enabling the airbag housing to be fastened to a vehicle. The bottom, the side walls, the end walls, and the fastening section are formed from a single sheet metal blank.

Airbag housing for an airbag module

The invention relates to a knee airbag module having a housing, an airbag accommodated in the housing and a substantially cylindrical gas generator () accommodated in the housing for filling the airbag, wherein the housing has an upper wall () and a peripheral side wall having a front section, a rear section () and two side sections. In this connection, at least one side section has, adjacent to the front () section, an opening () through which one end () of the gas generator () passes at least in part through the side wall. From each of the two side sections a respective fastening flange () extends with a respective fastening section () having a fastening surface. In order for the fastening surfaces to be relatively short, the fastening surfaces overlap the radial extension of the gas generator () in a vertical projection direction at least, wherein at least the fastening section () of the fastening flange () which is adjacent to the opening () is spaced apart from the end () of the gas generator () facing same. Furthermore, in order to achieve simple mounting of the gas generator, the region of the side wall section in which the opening () is disposed can extend obliquely with respect to the gas generator axis.

Knee airbag module

A fastening arrangement has an airbag module housing for receiving an airbag and a gas generator, and a firing channel () to which the airbag module housing can be fixed via form-fitting elements (). The form-fitting elements () enter into engagement with correspondingly designed receiving devices (), and a flange () with passage openings () for the passage of fasteners for the final fastening of the airbag module housing () to the firing channel () or an instrument panel is arranged on the airbag module housing ().
