摘要:
An adjustment device is disclosed for carrying out at least one adjustment function, such as for a motor vehicle seat. The device includes a drive in the form of a planetary gear mechanism. The mechanism has a planet carrier and an output. The output is stopped by a brake device when the drive is not actuated. The planet carrier cooperates with the brake device to release the brake device.

A vehicle seat has a seat adjuster. The seat adjuster includes a brake acting between a stationary part and an adjustable part. By use of the brake, the adjustable part can be blocked in a variety of positions in both adjustment directions on the stationary part and which can be applied by means of a freely switching element. An adjusting device acts on the freely switching element for selectively adjusting the adjustable part in both directions. An additional locking mechanism is provided which when the adjusting device is not in operation, automatically engages and when the adjusting device is not in operation automatically disengages.

A drive device for a motor vehicle seat (1) has a mount (22), a drive (24) which is mounted to the mount (22), so as to be pivoted about a first axis (A), an output (25) which is mounted to the mount (22), so as to be rotated about a second axis (B), and a transmission. The transmission transmits a driving pivot movement of the drive (24), which moves the drive (24) from an initial position into a deflected position, to the output (25) and causes a rotating movement of the output (25). At least one rolling body (26) is provided as the transmission. The rolling body (26), in the initial position and during the driving pivot movement of the drive (24), is in friction contact both with the drive (24) and simultaneously with the output (25) and rolls along same, and releases during the pivot movement back into the initial position.

An adjustment mechanism comprising a casing, an inlet member that is moveable relative to the casing; an outlet sprocket provided with a circular set of teeth and mounted to pivot in first and second bearings that are secured to or integral with the casing and that flank the outlet sprocket, said outlet sprocket being connected to the inlet member via a transmission device contained in the casing. The casing is provided with at least one side opening facing the set of teeth on the outlet sprocket, so as to enable said outlet sprocket to mesh with an external member.

An adjusting device for a vehicle seat includes a brake housing that is centered about an actuating rotational axis. the brake housing is formed in a radial direction of the actuating rotational axis and inlcudes a housing element that is generally circular and has a outer side wall, and upper wall and an inner side wall.

A rotation transmitting system comprises drive and driven wheels mounted on a stationary hub for rotation about a common axis. Radially spaced surfaces on the hub and driven wheel form a space in which clamping bodies are mounted. The space includes wedge portions in which the bodies are disposed, and a spring biases the bodies in a locking direction whereby the bodies prevent rotation of the driven wheel in respective directions of rotation. The drive wheel carries a claw member which forces a respective body out of its locking position when the driven wheel is rotated in either direction, thereby unlocking the driven wheel for rotation. A lost-motion connection between the drive and driven wheels connects those wheels for common rotation after the driven wheel has been unlocked.

A clamping-roller freewheel for an adjustment device in a motor vehicle includes a housing, a cylindrical lateral surface that defines an axis, at least one roller, an output shaft that is central to the axis, and a clamping contour which is located on the side of the roller opposite from the cylindrical lateral surface and rotationally connected to the output shaft. The clamping contour is a double clamping contour. The roller is allocated to the double clamping contour. The double clamping contour has a left and a right clamping area. A clamping action arises due to the cooperation of the roller with the left or right clamping area, depending on the direction of rotation, and the cylindrical lateral surface.

An irreversible adjustment mechanism comprising a pivoting lever resiliently assisted to a neutral position, an intermediate pivoting part connected to the lever by a driving stage adapted to move the intermediate part only when the lever moves away from its neutral position, a fixed collar, an output part delimiting with the collar wedge-shaped hollow spaces directed in opposite directions, and a locking stage ensuring an irreversible transmission between the intermediate part and the output part with a certain angular play of the intermediate part. The intermediate part is braked with a braking torque sufficient to lock the intermediate part in each return movement of the input part to its neutral position.
