20110138940 | ADJUSTMENT FITTING - Adjustment fitting, in particular for a vehicle seat, comprising a first fitting part and a second fitting part that can be rotationally adjusted relative to the first fitting part about an axis of rotation. An external gear, which has internal teeth and into which an internal gear that is associated with the second fitting part and has external teeth is inserted like an eccentric gear, is associated with the first fitting part. The internal gear forms an eccentric receiving space towards the axis of rotation. The adjustment fitting further comprises an eccentric member that is rotatably inserted into the eccentric receiving space and is equipped with a drive shaft for driving the eccentric member, and a cap for covering the open receiving space. The cap is eccentrically designed relative to the axis of rotation, penetrates into the eccentric receiving space by means of an axially downward-pulled sealing edge, and seals the receiving space as the sealing edge is preloaded in a radially outward direction. The adjustment fitting is easy to mount, while the cap ensures a secure sealing action regardless of the axial height of the adjustment fitting. | 06-16-2011 |
20110140493 | ADJUSTMENT FITTING - An adjustment fitting, in particular for a vehicle seat, includes a first fitting part and a second fitting part that can be rotationally adjusted relative to the first fitting part about an axis of rotation. An external gear, which has internal teeth and into which an internal gear that is associated with the second fitting part and has external teeth is inserted eccentrically to the axis of rotation like an eccentric gear, is associated with the first fitting part. The internal gear forms an eccentric receiving space towards the axis of rotation. The adjustment fitting further comprises an eccentric member that is rotatably inserted into the eccentric receiving space, and a drive shaft for driving the eccentric member. The external gear is designed as a ring gear that has a bottom and an external wall which axially extends beyond the internal teeth and embraces the external teeth of the internal gear by means of a radially inward-oriented collar. In addition, the internal gear comprises an internal wall which axially extends beyond the external teeth and axially penetrates the collar. The fitting parts are thus securely fastened in the axial direction while access is made easy, especially for mounting the adjustment fitting on a vehicle seat or a seat adapter. | 06-16-2011 |
20110140494 | ADJUSTMENT FITTING - An adjustment fitting, in particular for a vehicle seat, comprising a first fitting part and a second fitting part that can be rotationally adjusted relative to the first part about an axis of rotation. An external gear, which has internal teeth and into which an internal gear that is associated with the second fitting part and has external teeth is inserted eccentrically to the axis of rotation like an eccentric gear, is associated with the first fitting part. The internal gear forms an eccentric receiving space towards the axis of rotation.

The external gear is designed as a ring gear that has a bottom and an external wall which axially extends beyond the internal teeth. Furthermore, a holding element is provided which can be axially slid against the internal gear in the external wall, is mounted on the external wall, and secures the internal gear against the bottom of the ring gear. The holding element allows the axial tolerance between the internal gear and the external gear to be adjusted. | 06-16-2011 |
20110154925 | METHOD FOR MANUFACTURING AN ADJUSTMENT FITTING - A method for producing an adjustment fitting, particularly for a vehicle seat is provided, whereby an outer wheel is associated with a first fitting part, the wheel having inner toothing, and having an inner wheel that can be associated with a second fitting part, the wheel having outer toothing, wherein the inner wheel having the outer toothing is inserted into the outer wheel having the inner toothing eccentrically to a rotational axis in the manner of a wobble mechanism, wherein partial eccentric elements are inserted rotatably with respect to each other in an eccentric receiving chamber formed between the rotational axis and the inner wheel so as to produce variable eccentricity, wherein a transmission element having an engagement element for actuating the partial eccentric element is inserted such that the engagement elements interacts with a catch of the partial eccentric element. In spite of the production tolerances of the components, overall higher quality and higher operational safety of the produced adjustment fitting are to be achieved. For this purpose, the geometry of the partial eccentric element is measured, and the geometry of the transmission element is individually adapted according to the data of the measurement before inserting the transmission element. | 06-30-2011 |
