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: A steering wheel having a steering wheel body (10) having a first force transmitting component, and a horn actuation element. The horn actuation element having a horn actuation surface (23) and having a second force transmitting component. A load cell (30) is provided having a sensitive element that changes at least one of its electrical properties in response to a compression force. The sensitive element placed between the first and second force transmitting components. At least one elastically deformable element is provided between the steering wheel body (10) and the horn actuation element. When a pushing force is applied to the horn actuation surface (23) the force applied to the sensitive element changes. In a resting state of the steering wheel a compression force is applied to the sensitive element by the first and second force transmitting components by a preload and in that the compression force applied to the sensitive element is reduced when a pushing force is applied to the horn actuation surface (23).
