Lehnenneigungseinstellbeschlag für Sitze, insbesondere Kraftfahrzeugsitze

摘要

The articulated fitting has a stationary articulated part associated with the seat part and a swivelable articulated part associated with the backrest. These articulated parts are connected with one another via an adjusting shaft. An adjusting and locking device which is constructed as a gear unit and determines the position of the two articulated parts relative to one another is provided. The adjusting shaft has an eccentric portion for supporting one articulated part, this eccentric portion being formed by two wedge segments which are inclined relative to one another and engage regions of a driver of the adjusting shaft, by a driver arm engaging between the narrow sides of the wedge segments, and by a torsion spring which spreads apart the broad sides of the wedge segments with its spring legs. Therefore, the invention minimizes the play occurring between the driver arm and wedge segments as a result of operation and manufacture.
