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 gearing for an adjusting device of a motor vehicle is provided. The adjusting gearing having a gearing housing, having a drive input wheel which is arranged in the gearing housing and which has bearing collars formed at both sides of the drive input wheel, and having a drive output wheel which is arranged in the gearing housing and which meshes with the drive input wheel and the axis of which is aligned substantially perpendicular to the axis of the drive input wheel. The adjusting gearing further comprising a single part gearing housing having a first housing chamber for holding the drive input wheel and having a second housing chamber for holding the drive output wheel, a bearing point which is formed in the first housing chamber and which serves to hold a first bearing collar of the drive input wheel and a bearing point which is formed in the second housing chamber and which serves to hold a first bearing collar of the drive output wheel, and axially adjustable bearing bushes having cylindrical bushes, which are matched to the inner diameters of the housing chambers for centering second bearing collars of the drive input wheel and of the drive output wheel.

A motor vehicle seat back structure comprising a backrest support frame which consists of a surface turned towards the seat user's back, a lordosis support which is arranged on the front part of the backrest support frame for supporting the user's back and an adjusting device for vertically adjusting the lordosis support position with respect to the extension plane of said backrest support frame. The adjusting device comprises at least one adjusting element operably connected to the lordosis support and at least one sliding element which is displaceable with respect to said adjusting element and interacts therewith in such a way that when the sliding element moves, the adjusting element is displaced with a directional component perpendicularly to the displacement direction of the sliding element and performs an action on said lordosis support in the 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.

An adjustable mechanism for a motor vehicle is used to adjust an adjustable element in a motor vehicle, especially a seating part. Said mechanism comprises a spindle nut comprising an axis, said spindle nut co-operating with a thread spindle and comprising external toothing on the external surface thereof which is in contact with an additional drive element. The external toothing of the spindle nut is formed by recesses in the external surface of the spindle nut which are inwardly turned in a radial manner, the teeth depths thereof diminishing in the direction of at least one axial end of the spindle nut.
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.
