  • Patent number: 11414038
    Abstract: 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.
