A wobble joint fitting for an adjustment device of a motor vehicle seat comprises a first fitting part, a toothed eccentric gear that has an eccentric hole and a collar, and an eccentric comprising a rotatable drive part, a control part and wedge segments, the control part comprising control surfaces that come to abut against the wedge surfaces. The fitting further comprises a second fitting part that is adjustable with respect to the first fitting part. A latching part is provided which has at least one latching tooth, biased only in an actuation position of the latching part into engagement with a latching recess, and having an actuating flank. The control part comprises an actuating portion which abuts against the actuating flank and, during a rotary movement of the control part, presses the latching tooth into abutment against the collar, and biases it into engagement into a latching recess.

A wobble joint fitting for an adjustment device of a motor vehicle seat, in particular for a seat back hinge fitting, comprises (a) a first fitting part comprising an internal ring gear, (b) a toothed eccentric gear that engages the internal ring gear and that has an eccentric hole, (c) an eccentric to which a rotatable drive part is associated and which comprises wedge segments, (d) a second fitting part that is adjustable with respect to the first fitting part, and (e) a wrap spring. The wrap spring is a flat open spring ring and extends over an angle of less than 360&#xb0;. The eccentric gear comprises a collar for the spring ring to fit against.

A wobble joint fitting for a vehicle seat has a first joint arm, which carries an internal gear and forms a first bearing surface, which are central to a main axis, and a second joint arm to which an eccentric gear is allocated, which comprises an externally toothed pinion and a second bearing surface. The pinion and the second bearing surface are central to an eccentric axis. An eccentric driving part is disposed in the area between the first bearing surface and the second bearing surface. Clamping parts, in a clamping state, displace the eccentric axis relative to the main axis. The eccentric driving part defines the eccentric. The rotary drive of the eccentric driving part causes a rotation of the pinion relative to the internal gear even without the clamping parts being present, wherein only play compensation is not obtained without the presence of the clamping parts.

A hinge mounting for a motor vehicle seat with one hinge axis, one actuation part, one first hinge part having an inner toothed surface centered with respect to the hinge axis, one second hinge part with at least one stop arm comprising a toothed region cooperating with the inner toothed surface, being disposed for pivotal movement about a pivot axis disposed on the second hinge part and comprising a projection and having an actuation region that cooperates with the actuation part, and with a control part that is connected to the first hinge part and comprises a cam for the projection to fit against, the cam comprising several portions, the engagement region being located between the front holding region and a rear holding region, that, when the projection moves from the front holding region to the rear holding region, a movable baffle associated with the engagement region bridges the interposed engagement region for preventing the projection from engaging therein, the baffle being inoperable when the projection moves in the opposite direction so that the projection is free to move into the engagement region.

The forwardly movable vehicle seat has an underframe including a longitudinal adjusting device that has two pairs of rails, two catch devices and one actuation lever for actuating the catch devices. The vehicle seat further has a seat pan that is carried by the underframe. The seat pan includes a seat back that is pivotal about a seat back axis and on which there is disposed a release lever. In the actuation state, the seat back is unlocked for tilting, the actuation lever being actuated and the catch device unlocked when the seat back is tilted forward so that the seat can be brought from an initial position to a forwardly moved position. There is provided a memory mechanism that ensures that the seat, when being moved back from its forwardly moved position, resumes its initial position.

Forwardly movable vehicle seat with an underframe and two pairs of rails

The invention relates to a forwardly movable vehicle seat having an underframe including a longitudinal adjusting device, the longitudinal adjusting device including two pairs of rails, two catch devices and one actuation lever for actuating the catch devices. The vehicle seat further includes a seat pan that is carried by the underframe, and a seat back that is pivotal about a seat back axis and on which there is disposed a disengagement lever. In an actuated condition, the seat back is unlocked so as to be foldable, the actuation lever being actuated and the catch devices unlocked and the seat being allowed to be brought from an initial position to a forwardly moved position when the seat back is folded forward.

A centering photographic material winding device for the winding or unwinding of a photographic material web onto or from a winding core. The winding device includes a winding core seat which is adapted for receiving a winding core moveable on the winding core seat. The winding core is centered by two push members which are coupled in their movement for the displacement and centering of a winding core received on the winding core seat between the push members in that the push members evenly move towards one another.
