  • Patent number: 4671555
    Abstract: The invention relates to an air guidance device which responds to externally applied forces by movement whereby the externally applied forces do not damage said air guidance device. Embodiments of this invention include at least one hinge pivotally attached to the body wall at the rear of a motor vehicle. Said hinge arrangements allow air guidance device to be pivoted upwardly when subjected to external forces such as a washing brush of a car wash when said brush passes over a passenger car in a driving direction. The air guidance device so configured is neither damaged when driving through the car wash, nor is the washing cycle unintentionally interrupted.

  • Patent number: 4656807
    Abstract: A decorative strip detachably secured at the support flange of a motor vehicle includes two essentially parallelly extending support sections of which one abuts at the bottom side of the support flange. Detent members are provided at a retaining clamp fastened at a flange bolt which engage form-lockingly and force-lockingly into one of several detent receiving elements of the support sections arranged one behind the other, whereby the apertures are preferably provided at the support section opposite the support flange. A decorative strip is created by this arrangement which with a secure fastening is adjustable relative to the body as well as adapted to be installed and disassembled in a simple manner.
