Patent ID: 11214177

Abstract:
The present disclosure relates to a rotational device for a vehicle seat having an upper connecting element and a lower connecting element, a ring shaped profile rail, where the ring shaped profile rail is guided by several rollers in a manner rotatable about a rotational axis, where the several rollers are each mounted in a manner rotatable about roller axes, and the rollers are in contact with interior contact surfaces of the profile rail in such a way that the rollers upon rotation of the profile rail roll off on the interior contact surfaces, thereby guiding the profile rail in its rotational movement about the rotational axis, whereby the upper connecting element is connected to the lower connecting element via the rotatable guided ring shaped profile rail in such a way that these can be twisted in relation to one another.According to the present disclosure it is provided for the roller axes of the several rollers to be determined such that the rollers are in contact with and roll off on several interior contact surfaces of the profile rail with different orientations, whereby each roller in and of itself can be in contact with and roll off on merely one of the several interior contact surfaces of the profile rail.
