A spindle or worm drive for adjustment devices in motor vehicles, secured with a fixed spindle or a fixed toothed rack to the first of two parts which can be adjusted in relation to each other, provided with a gear mechanism which is connected to the second of the two parts which can be adjusted in relation to each other. The gear housing is free from backlash and is enclosed by at least one bearing shell (5,6) such that it is pivotable about at least one axis, said bearing shell consisting of two bearing plates (5,6) which fit into one another and which can be joined to each other after enclosure of the gear housing (4). The gear housing (4) is made of plastic and is provided with a concave or convex housing part (42, 43) which is surrounded by a convex or concave bearing shell section (54, 64) made of a material which is suitable for receiving crash forces, especially a metal material.

The invention relates to a device for adjusting the seat depth of a motor vehicle seat, with a seat depth adjustment part (2) which is essentially movable in the direction of travel in relation to the lower part (1) of the motor vehicle seat, a driving device for the seat depth adjustment part (2) and a tracking device (5) for a cushion material covering the seat depth adjustment part (2). The adjustment unit (4) driving the seat depth adjustment part (2) and the tracking device (5) for the cushion material form a structural and functional unit which makes it possible for the seat depth adjustment device of the motor vehicle seat to be preassembled in a simple manner, to be constructed very compactly and to easily be adapted to the circumstances of a motor vehicle seat.

The invention relates to a motor vehicle seat comprising a backrest, which provides a support for the back of a seat occupant when in the position of use, and a pivotally mounted upholstery carrier for seat upholstery, defining a seat surface for a seat occupant when in the position of use, in addition to a folding mechanism for folding the upholstery carrier in front of the backrest such that the upholstery carrier extends substantially along the backrest when the latter is in the position of use. According to the invention, the folding mechanism (1,2) comprises a pair of levers (1), wherein both levers (11, 12) are hingedly coupled to each other at a knee joint (10), forming an acute angle (A) at said knee joint (10), and such that the acute angle (A) is transformed into an obtuse angle (B) when the upholstery carrier (T) is folded out of the position of use in front of the backrest (R).

The invention relates to a motor vehicle seat back structure comprising a backrest support frame which consists of a surface turned towards the seat user's back, a lordosis support which is arranged on the front part of the backrest support frame for supporting the user's back and an adjusting device for vertically adjusting the lordosis support position with respect to the extension plane of said backrest support frame. Said invention is characterised in that the adjusting device comprises at least one adjusting element (11, 12) operably connected to the lordosis support and at least one sliding element (21, 22) which is displaceable with respect to said adjusting element (11, 12) and interacts therewith in such a way that when the sliding element (21, 22) moves, the adjusting element (11, 12) is displaced with a directional component (x) perpendicularly to the displacement direction (y, z) of the sliding element (21, 22) and performs an action on said lordosis support in the direction (x).

The invention relates to a seat assembly for a motor vehicle seat, comprising a seat frame, which defines a seating surface for a motor vehicle occupant and a pivotally mounted backrest, which can be folded onto the seating surface about a pivoting axis. According to the invention, the pivoting axis (5) is displaced along a predetermined path, when the backrest (R) is folded forwards onto the seating surface (F).

The invention relates to a vehicle seat (F) comprising a lower seat frame (U), which defines a seat surface, and a backrest (L). The backrest (L) extends along a backrest longitudinal axis (B), and the backrest longitudinal axis (B) runs at an inclination angle relative to the seat surface when the backrest (L) is in a use position in which a person (P) can sit on the vehicle seat (F) as intended. The vehicle seat also comprises a drive device with at least one drive unit (1) which allows the backrest (L) located in the use position to be rotated relative to the backrest longitudinal axis (B) in an actuated manner by an external force, one longitudinal side of the backrest (L) being inclined backwards relative to a pivot axis (A) more steeply than the other longitudinal side. According to the invention, at least one switchable transmission unit (2) is provided, by means of which a drive torque generated by the drive unit (1) can be divided between the backrest longitudinal sides in order to rotate the backrest (L) relative to the backrest longitudinal axis (B).
