  • Steering wheel with vibration damping mass
    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.
    Type: Grant

  • Device for damping vibrations
    Patent number: 9291233
    Abstract: An apparatus for the damping of vibrations in a steering column in a motor vehicle, having a mounting (10) and an accommodation device (11) elastically supported in the mounting (10) to which a gas generator (20) is secured, a separate supplemental weight (30) is secured to the gas generator (20) or to the accommodation device (11) to provide desired vibration damping characteristics of the steering column assembly.
