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 knee airbag for a motor vehicle is described. This knee airbag extends in its installed state along a longitudinal direction (X) from a rear end to a front end. The airbag skin () of the knee airbag exhibits a front section () and a rear section () and a connecting line for contouring of the airbag is located on the rear section (). In order to simplify the assembly of the knee airbag, the connecting line mainly extends transverse to the longitudinal direction (X) and shortens the rear section () in longitudinal direction.

Knee airbag

A safety arrangement for use in a motor vehicle includes a blocking unit () and a drive () to drive the blocking unit () from a position where it is flush with the dashboard () to a forward position where it will block movement of the knees of an occupant of a seat (). A timing arrangement () is provided which controls the drive to return the blocking unit to an initial position after a predetermined period of time. An energy-absorbing element, which may be an air-bag () absorbs energy as the blocking unit () is moved from the operative position by a force applied to the blocking unit by the knees of a seat occupant.
