Abstract: A swash-plate-type gearing for adjustment devices includes a housing; an outer part, which has an inner toothing concentric with a joint axis; and an inner part with an outer toothing concentric with an eccentric axis, which runs parallel to the joint axis, offset by an off-centre distance. The gearing also includes an engagement region, in which the outer toothing is engaged with the inner toothing and which is located on a straight line intersecting the joint axis and eccentric axis, in each case at a right angle, with the eccentric axis lying on this straight line between the joint axis and engagement region; and a free space located 180° opposite the engagement region and on the straight line, in which free space the outer toothing is disengaged from and at a distance from the inner toothing. A locking part is provided having a locking region located in the free space.

Abstract: Actuating drive having: a transmission including a housing, a transmission gear engaging a driveshaft, a bearing, and a spindle rotatable about a rotational axis and extending through an inner thread of the transmission gear and outlets of the housing. The housing has a cylindrical bore receiving the bearing and defining a cylinder axis. The bearing is delimited by a three-dimensional area, the largest cross-sectional area of which is circular and, when viewed in the direction of the cylinder axis, perpendicular to the cylinder axis in the intersection of the cylinder axis and the rotational axis. The cross-sectional area decreases with increasing distance from the intersection in both directions of the cylinder axis. The bearing has two bearing shells, each having a bearing opening centered relative to the rotational axis, which the spindle passes through, and in which the transmission gear is rotatably mounted.

Abstract: A seat support frame of a motor vehicle seat includes a seat frame which has left-hand and right-hand side parts, and a transverse tube connecting the two side parts to one another at the front. The seat support frame has a seat shell supported by the seat frame and composed of two sheet metal parts firmly connected to and arranged at a distance from one another, specifically upper and lower shells. The upper and lower shells form a channel running parallel to the transverse tube. The seat support frame includes an adjusting device which, on one side, is connected only, at a front region of one of the side parts and, on the other side, is connected in an articulated manner to the end region of the channel adjacent to the side part, and allows the distance of the seat shell relative to the transverse tube to be adjusted.

Abstract: A seat depth adjustment device for a vehicle seat that can be adjusted in the seat depth thereof electrically by an electric motor or manually by an operating lever includes a single-piece support plate made of plastic. The support plate includes (a) a support part, which extends in the sliding direction, (b) a front apron, (c) two guides, which extend parallel to each other in the sliding direction and are arranged at a distance from each other and are formed in the support part, and (d) a slot for a detent spring, which slot is formed in the support part and extends perpendicularly to the sliding direction. The devices further includes (e) a space for accommodating at least a part of the operating lever or of the electric motor and for the fastening thereof, which space is open downward and is delimited by the support part and the front apron.
