摘要:
A spindle drive for longitudinally adjusting a motor vehicle seat is provided. The spindle drive comprising an adjustment rail that can be longitudinally adjusted relative to a body mounted rail and an adjusting mechanism that includes a driving worm connected to a driving device as well as a spindle nut, the external teeth of which mesh with the external teeth of the driving worm, and the internal teeth of which mesh with the external thread of a spindle. The spindle nut is formed by a hybrid spindle nut that has a functional part, which is located in the force flux between the driving worm and the spindle, and at least one strengthening part, deflecting crash forces from the adjustment rail into the spindle.

An adjusting means for adjusting two vehicle parts relative to each other, in particular for the longitudinal setting of a vehicle seat is provided. The adjusting means comprising an adjusting gear unit arranged on a first vehicle part and a spindle arranged on a second vehicle part, which extends in longitudinal direction, is in engagement with the adjusting gear unit and along which the adjusting gear unit is movable for adjusting the first vehicle part relative to the second vehicle part. There is provided a reinforcement part which supports the adjusting gear unit with respect to the first vehicle part in the longitudinal direction of the spindle such that due to the reinforcement part with forces introduced in the longitudinal direction from the first vehicle part into the adjusting gear unit the adjusting gear unit is supported with respect to the first vehicle part with a higher rigidity than with forces introduced against the longitudinal direction.

A longitudinal guide rail for a motor vehicle seat. The rail includes two elongated guide rails that engage with one another and are displaceable in relation to one another in the longitudinal direction of the rails, a retaining bracket for a seatbelt buckle, which is fastened to one of the two guide rails, a slot that is provided in one of the guide rails, through which a fixing section of the retaining bracket is guided into a space enclosed by the two guide rails and a fixing point, at which the fixing section of the retaining bracket is connected to one of the guide rails. The fixing section when viewed from the longitudinal direction of the rails, extends beyond the slot and the fixing point, also viewed from the longitudinal direction of the rails, is located at a distance from the slot.
摘要:
A memory device, for a rail longitudinal guide for a motor vehicle seat, comprising two longitudinal guide rails displaceable towards each other, for the setting of the longitudinal seat position, a first memory module, which may be displaced along one of the two guide rails to set a memory position, a locking device for locking a set memory position, a second memory module, arranged on the second of the guide rails and a stop which, on reaching a relative position of the two guide rail corresponding to one of the memory positions, engages with a counter stop on the first memory module. The second memory module comprises a base body made from plastic, by which the latter is fixed to the second guide rail.

A motor vehicle seat. The seat has a seat frame; a seat back pivotally mounted on the seat frame and which can be tilted forward out of its position of use and toward a seat surface of the seat frame; a longitudinal guide with which the seat frame is displaceable in the longitudinal direction of the seat in order to adjust the longitudinal position of the seat; a fixing device for fixing the seat frame in a previously adjusted longitudinal position of the seat, an actuating element for releasing the fixing device thereby enabling the seat frame to be displaced in the longitudinal direction of the seat, a coupling mechanism, which acts upon the actuating element and releases the fixing device when the seat back is tilted forward toward the seat surface, and a memory device by means of which the seat frame can be automatically held in a preset longitudinal position of the seat, which is defined as a memory position.
摘要:
A longitudinal guide for vehicle seats, including two elongate rails, each including a lower rail, an upper rail supported on the lower rail and displaceable in a longitudinal direction, and two bearing areas for guiding means, the bearing areas lying diagonally opposite to and biased against each other, each upper rail and lower rail having an L-shaped region, if viewed in profile, formed by a base leg and an L-leg protruding from the base leg substantially perpendicularly, and two end regions adjoining the L-shaped region, each end region of the upper or lower rail together with the end region of the associated lower or upper rail forming an embracing area by mutually hooking, the end regions of the upper rail forming the bearing areas with opposite portions of the associated lower rail, and a plurality of balls being supported in a first bearing area on the end region.
