Abstract: The invention relates to a device for adjusting a vehicle seat, the frame structure (4, 5, 6) of which can be adjusted using drive motors (40) having presupported gear units (39), and the vehicle seat is accommodated on two seat rails (1, 2) arranged parallel to each other. The frame structure (4, 5, 6) of the vehicle seat can be adjusted spherically using lifting elements (8, 9, 10) in two planes separated from each other.

Abstract: Disclosed is a seat adjusting device (10) and a method for operating the same. The seat adjusting device (10) includes two seat parts (15, 16, 17, 18, 19) positioned such that they are movable relative to each other and/or relative to a fastening surface (12, 14) and which are interconnected via at least one ratchet mechanism (56). The ratchet mechanism (56) includes a bidirectionally active rotary drive unit (54) which is operatively connected via a connecting element (52, 64, 72, 78) with at least one pneumatic linear actuator (52) which contracts in an axial direction when acted upon by a certain pressure (42, 43), which causes the rotary drive unit (54) to rotate.

Abstract: The invention relates to a device for adjusting a seat back (6) of a vehicle seat (4), in which a drive (9) that carries out adjusting processes is integrated. This acts on stagger gears (10, 22), with which the seat back (6) is moved within a range of inclination (13). A torsion element (24) is provided between the stagger gears (10, 22) that compensates the clearance in the stagger gears (10, 22) within a first range of adjustment (18) of the seat back (6) and functions as support for the driver motor within a further range of adjustment (19) of the seat back (6).

Abstract: A permanent magnet-excited small motor having an armature supported rotatably about a pivot axis, at least two permanent magnet poles surrounding the armature on opposed portions, and a pole housing, connecting the permanent magnet poles. In the region between the permanent magnet poles, the pole housing has flat faces, which are curved convexly outward.

Abstract: The invention is based on an apparatus for adjusting a vehicle seat, the position of which can be adjusted via one or more geared motors (8, 38, 41, 42), wherein the geared motors (8, 38, 41, 42) can be actuated via a control (24). A vehicle seat underbody (3, 32, 45) is supported at at least three points by means of driven lifting spindles (16), driven guide bars (28, 39, 40) or sliding fixtures (34, 35, 43), wherein at least one support point (16, 29, 34) can be varied relative to the other remaining support points of the vehicle seat in such a fashion that a spherical seat adjustment results.
