  • Patent number: 9663003
    Abstract: 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.

  • Patent number: 9139112
    Abstract: 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 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.

  • Patent number: 8678970
    Abstract: Adjustment fitting, in particular for a motor vehicle seat, having a first fitting part and having a second fitting part that is rotationally adjustable relative to the first fitting part about an axis of rotation, wherein the first fitting part has associated with it an outer wheel with internal teeth, in which wheel is inserted, in the manner of a wobble mechanism, an inner wheel with external teeth hat is associated with the second fitting part, and wherein the inner wheel forms a receiving space that is eccentric to the axis of rotation, and having an eccentric cam rotatably inserted in the eccentric receiving space, having a drive shaft for driving the eccentric cam. A central seal is placed in an axial gap between the two fitting parts.

  • Patent number: 8444521
    Abstract: 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.

  • Patent number: 8201887
    Abstract: A fitting is provided that has a first fitting part and a second fitting part that can be rotated about a rotation axis relative to the first fitting part, wherein both fitting parts are held rotatably to one another in the axial direction by means of a retaining ring. For this purpose, a retaining ring overlaps the second fitting part in the axial direction, and is firmly connected to the second fitting part at that location, and pretensions the first fitting part against the second fitting part by means of a stop that is tilted inward against the radial direction. Such a fitting can be produced in a particularly cost-effective manner.

  • Publication number: 20120057926
    Abstract: An apparatus, in particular for a vehicle seat, comprising a fitting and at least one adapter plate connected with the fitting, is provided. The fitting comprises a first fitting part and a second fitting part rotatable about an axis relative to the first fitting part. The adapter plate is firmly connected with the first fitting part by means of at least one welding seam. The adapter plate includes at least one region which has a reduced wall thickness, and the welding seam is formed in the region of reduced wall thickness in the adapter plate.
