Abstract: An underframe for a height adjuster of a seat, in particular a vehicle seat, may have a base frame which is connectable to a vehicle floor, a seat frame which is adjustable relative to the base frame and has at least one frame part, and a spindle drive unit for adjusting the seat frame relative to the base frame. The spindle drive unit has a first bearing point, which is connected pivotably to the frame part, and a second bearing point, which is connected pivotably to the base frame. A height adjuster for the vehicle seat is also provided.

Abstract: A longitudinal adjuster in the interior of a motor vehicle, has an upper and a lower rail, between which at least one rolling body is provided. A projection is provided on the upper and/or lower rail, the projection forming a local contact point between the two rails.

Abstract: The invention relates to a motor vehicle seat, in particular to a rear seat for rear rows of seats of motor vehicles. Furthermore, the invention relates to a method for shifting a first and second component relative to a base part.

Abstract: The invention relates to a motor vehicle seat, in particular to a rear seat for rear rows of seats of motor vehicles. Furthermore, the invention relates to a method for shifting a first and second component (1, 6) relative to a base part (4), the first and the second component being connected to each other by a first rotational means (GL) and the second component and the base part being connected to each other by a second rotational means (GU).

Abstract: The invention relates to a fitting (10) for a vehicle seat, more particularly for a motor vehicle seat, comprising a first fitting part (11), a second fitting part (12) that is in geared connection with the first fitting part (11), an eccentric (27a, 27b; 127; 327) that is rotatably mounted on the fitting parts (11, 12), for driving a rolling movement of the first fitting part (11) and the second fitting part (12), a driver (21) for driving the eccentric (27a, 27b; 127; 327) and a brake for locking the fitting (10) against torque introduced at the output side in the rest state, with at least one wrap-spring brake (44) being provided as the brake, and the brake being acted upon by the driver (21) and the eccentric (27a, 27b; 127; 327).

Abstract: The invention relates to a fitting (10) for the seat of a vehicle, particularly a motor vehicle, comprising a first fitting part (11), a second fitting part (12) which is mechanically linked to the first fitting part (11), a locking eccentric, and a running eccentric (131), wherein the running eccentric (131) is mounted in relation to the first fitting part (11) and second fitting part (12) by way of a rolling bearing or sliding bearing bushing (28,33), wherein friction between the running eccentric (131) and the sliding bearing bushings (28,33) or between at least one sliding bearing bushing (28, 33) and the associated fitting part (11, 12) is lower than the friction between the locking eccentric and at least one of the fitting parts (11, 12).

Abstract: A fitting (10) for a vehicle seat, more particularly for a motor vehicle seat, comprises a first fitting part (11), a second fitting part (12) that is in geared connection with the first fitting part (11), a driver (21) and wedge segments (27a, 27b), which at least partly define a cam that is rotatably mounted on the first fitting part (11) for driving a rolling movement of the first fitting part (11) and the second fitting part (12) against one another, and with a first sliding bearing (28) or rolling bearing, by way of which the wedge segments (27a, 27b) are mounted on the second fitting part (12) with a small amount of friction, at least a first (27a) of the two wedge segments (27a, 27b) being mounted on the first fitting part (11) with a small amount of friction by way of a second sliding bearing (41) or rolling bearing.

Abstract: The invention relates to a fitting (10) for the seat of a vehicle, particularly for a motor vehicle, comprising a first fitting part (11), a second fitting part (12) which is mechanically linked to the first fitting part (11), a locking eccentric which is provided primarily to lock the fitting (10), a running eccentric (31) which is primarily provided for driving a relative rolling movement of the second fitting part (12) on the first fitting part (11) in order to adjust the fitting (10), and a driver (21) which controls the locking eccentric at the beginning of the adjusting movement in order to cancel the locking effect and which drives at least the running eccentric (31) during the adjusting movement. The rotating driver (21) impinges upon the rotating running eccentric (31) without any lateral force.
