A steering wheel includes a steering wheel body and a base. The base carrying an inflator and an airbag package, such that the base, the inflator and the airbag package form a first sub-assembly. The base is connected to the steering wheel body at least indirectly via at least one elastic element, such that the sub-assembly can move relative to the steering wheel body in at least one direction so that the whole sub-assembly serves as a vibration damping mass. The steering wheel also includes a cover element with a roof extending over the airbag package, and at least one horn sensor generating a signal when a pressing force exceeding a predefined value is applied to the roof. The cover element is not rigidly connected to the base, such that the sub-assembly can move relative to the steering wheel body under deformation of the elastic element while the cover element does not move relative to the steering wheel body.

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.
