Abstract: A steering wheel unit (10) for a motor vehicle having, a steering wheel body (12), an airbag module (20) accommodated in a hub region of the steering wheel body (12), which includes a housing (22), an inflator connected to the housing (22), and an airbag (29) folded into the housing (22), and at least three axial positioning units which define the axial position of the housing (22) when not pressed down with respect to the steering wheel body (12). Each of the three axial positioning units include an axial positioning element (40) connected on the module side to the housing (22), or an axial positioning element connected to the steering wheel body on the steering wheel body side, wherein the positioning element features a metal support unit (42). The at least three support units (42) are elements separate from each other.

Abstract: An airbag system (3) having a two-chamber airbag (4), wherein the main chamber has an impact surface (7) which the vehicle occupant can contact and a support surface (8) with the main chamber (5) supported on an interior fitting (2) of the vehicle. A secondary chamber (11) forms a support cushion for the main chamber (5), the main chamber (5) having a greater volume than the secondary chamber (11). The secondary chamber (11) is located between the support surface (8) and the interior fitting (2). The airbag (4) has an overflow protective element (24) between the main and secondary chambers (11). A first gas generator (16) inflates the main chamber (5) and a second gas generator (17) inflates the secondary chamber (11), wherein both generators (16, 17) or only the first generator (16) can be controlled for inflating the main chamber (5) as desired.
