Abstract: A longitudinal adjustment unit of a seat, particularly of a seat in a motor vehicle can include a housing with a through-hole arranged along a longitudinal axis and having a first spindle opening and a second spindle opening, a spindle that can be guided through the through-hole along the longitudinal axis through the housing, a spindle nut, and a screw driving the spindle nut and supported in the housing via a bearing located on both sides. The spindle nut can be supported in the housing in the longitudinal axis so that it can be rotated bidirectionally and axially. Also, at least one fastener can be provided, through which the spindle is connected to the spindle nut in a torque-free manner.

Abstract: An adjusting device for adjusting a vehicle seat along a sliding axis, having a first and a second lower rail, both of which are fixedly connected with the vehicle, a first upper rail, which is slidably supported in the first lower rail in parallel to the sliding axis and a second upper rail, which is slidably supported in the second lower rail in parallel to the sliding axis. The first lower rail and the first upper rail can enclose a first cavity and the second lower rail and the second upper rail enclose a second cavity. A first spindle can be arranged in the first cavity and non-rotatably connected to the first lower rail and a second spindle can be arranged in the second cavity and non-rotatably connected to the second lower rail.

Abstract: A gear for an adjusting device in vehicles for adjusting two vehicle parts adjustable relative to each other, in particular, for adjusting two parts of a seat adjusting device, a window lifter, or a sun roof, the gear including a drivable drive screw having gear teeth, a spindle nut, which has spindle nut teeth engaging with the screw teeth, and an internal thread, using which the spindle nut can be brought into engagement with a threaded spindle of the adjusting device, and a gear housing, which accommodates and supports the drive screw and the spindle nut. The spindle nut is made at least partially of metal, and the drive screw is made of plastic, and the gear housing includes a first bearing section made of plastic for supporting the spindle nut and a second bearing section made of metal for supporting the drive screw.

Abstract: Drive of a seat adjusting device, especially for motor vehicles, with a spindle that is fastened on a first of two rails, which are adjustable with respect to each other, by means of at least one mounting located at the end of the spindle and with a transmission driven by a motor that is mounted on the second rail, whereby the mounting has one part as a base plate, from which two walls at a distance from each other extend upward and that at least one end of the spindle is fastened between these two walls.

Abstract: Drive of a seat adjusting device, especially for motor vehicles, with a spindle that is fastened on a first of two rails, which are adjustable with respect to each other by at least one mounting on one end of the spindle, and with a transmission driven by a motor that is mounted on the second rail, whereby the mounting is a single piece stamped bent part with a first area with at least one fastener opening and a second area that is offset upward relative to the first area for holding one end of the spindle, whereby the first area and the second area are connected to form a single piece by a transition area, whereby the second area is designed with a slot with legs lying opposite each other, at least in sections, and opposite a slot between which the end of the spindle can be fixed.
