Vehicle seat
First Claim
1. A vehicle seat, comprising:
- an oscillatory scissor-type stand having two pairs of rocker arms arranged at a distance from one another;
a pair of structural parts coupled to one or more of the rocker arms;
a pin extending between the pair of structural parts;
a damper articulated at two parts of the scissor-type stand, the two parts being movable relative to one another, wherein one end of the damper is articulated at the pin;
a bearing bushing between the pair of structural parts, the bearing bushing having an axial bushing opening on one of the pin and a tubular component part enclosing the pin, the bushing opening having a spherical longitudinal section with greatest diameters at axial ends of the bushing opening and a smallest diameter between the axial ends of the bushing opening; and
a bearing ring of the damper arranged between the structural parts without axial play and configured to enclose the bearing bushing by having a shorter axial length than the bearing bushing, the bearing ring 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.

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. The bearing bushing is arranged between the structural parts without axial play.
