  • Publication number: 20110284713
    Abstract: A vehicle seat having an oscillatory scissor-type stand and a damper that is articulated at two parts of the scissor-type stand which are movable relative to one another. One end of the damper is articulated at a pin that extends in transverse direction of the seat and extends between two structural parts arranged at a distance from one another in transverse direction of the seat at a part of the scissor-type stand. A bearing bushing is arranged with its axial bushing opening on a tubular component part enclosing the pin, wherein the bushing opening has a spherical longitudinal section with the greatest diameters at the two axial ends and the smallest diameter in the middle of the bushing opening. The bearing bushing is enclosed by a bearing ring of the damper having a shorter axial length than the bearing bushing and is arranged on the bearing bushing at an axial distance from the two ends of the bearing bushing so as to be secured against axial displacement.
