摘要:
An electrically height-adjustable head rest device of a motor vehicle seat having a head rest, one or two bars carrying the head rest, a cross member, which is connected to at least one bar and comprises an internal thread, and a motor-spindle unit comprising a spindle engaging the internal thread. On the cross member and/or on the motor-spindle unit there is provided a guide seat for a guide part.

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.
摘要:
An adjustment device and method for an automobile seat or steering column. The adjustment device has an adjustment mechanism including an electric actuator, such as an electric motor, with plug-in connections. A control unit with a signal generator applies an adjustment voltage to the connections during an adjustment process, and may also, either simultaneously with or without the adjustment voltage, apply an alternating signal voltage to produce at least one of a tangible motion or an audible motion.

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°. The eccentric gear comprises a collar for the spring ring to fit against.
摘要:
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.
摘要:
The side part of a vehicle seat, meaning either a seat side part or a side part of a seat back, comprises a layered structure. It has at least two layers. A first layer is a sheet steel part determining the shape of the side part. A second layer is a reinforcement body that has a material thickness in the y direction that is greater than the material thickness of the sheet steel part.

The actuator for a motor vehicle has an electric motor having an output shaft. A gear comprising a spindle nut and a gear case is connected to the output shaft. A spindle engages the spindle nut. A bracket forms an at least partial surrounding grip abut the gear case. A pivot bearing is provided between the gear case and the bracket. Further, an abutment lying substantially opposite the pivot bearing is formed between the gear case and the bracket.

The actuator for a motor vehicle has an electric motor driving an output shaft and a gear comprising a worm, a spindle nut and a spindle. The worm is rotatably connected to the output shaft. The spindle nut comprises a worm gear that engages the worm and also a spindle thread that engages the spindle. The worm has a worm axis and the spindle nut has a spindle nut axis. The worm axis and the spindle nut axis draw an angle alpha of between about 85° and about 5° and, in one embodiment, between about 70° and about 40°.
摘要:
A motor vehicle seat with a seat pan comprising a seat part and a supporting plate, said supporting plate being connected to the seat part via a guide for displacement in a longitudinal direction and comprising a front region forming the front edge of the seat pan. The supporting plate comprises a left and a right supporting wing. The left supporting wing forms the left front corner and the right supporting wing, the right front corner of the seat pan.

The seat adjuster device, for setting a first part of a seat in a motor vehicle relative to a second part, comprises a curved piece (40), connected to the first piece, having a centre (46) and a regular front face (48), a support piece (52), connected to the second part, mounted to rotate about the centre (46), with a first clamping bevel (60) and a second clamping bevel (62), a first clamping body (68), arranged between a first clamping bevel (60) and the front face (48), a second clamping body (68), arranged between a second clamping bevel (70) and the front face (48) and two elastic means, of which one is arranged between the first clamping body (68) and the support piece (52). The first clamping body (68) is tensioned in a first rotational direction such as to be pressed into the corresponding clamping gap in a clamped position.
