  • Patent number: 9623768
    Abstract: A holding device for an adjustment drive of a motor vehicle seat, having at least one connection flange formed from plastic material for fastening the holding device to the vehicle seat. A fastening clip having at least one holding clip, which can be adjusted between a locking position and an assembly position in an elastic manner, is formed on the connection flange on one side and a locking element is removably formed in a rest position on the other side. The locking element can be manually relocated through an opening in the connection flange from the rest position to a locked position in which the locking element blocks an elastic relocation of the holding clip into the assembly position.

  • Patent number: 9358902
    Abstract: A holding device for an adjustment drive of a motor vehicle seat has at least one channel for receiving a drive shaft which is mounted rotatably in a shaft casing and is connectable at one end to a drive unit and at the other end to an adjustment device. In order to provide such a holding device that permits a reliable arrangement of the shaft casing, in particular in a manner secure against rotation, provision is made for the channel to be formed for positioning the shaft casing in a manner partially offset in relation to the longitudinal axis of the channel.

  • Patent number: 9266448
    Abstract: An adjustment mechanism, particularly for the longitudinal adjustment of a seat of a motor vehicle, with a transmission housing (30) fastened at a first part (10), which is displaceable in reference to a second part (12), with a transmission being arranged inside the transmission housing (30). A spindle (40) projects from the transmission housing (30). The spindle (40) is coupled via a nut element (50) to a second part (12). The transmission housing (30) is made from plastic, with at least one repeatedly angled metal insert (60, 70) being embedded in the plastic. At least one wall (60b) of the metal insert (60, 70) is aligned orthogonal in reference to the axis (A) of the spindle and at least partially encompasses the spindle (40) on the side of the transmission housing (60) allocated to the nut element (30).

  • Patent number: 9242579
    Abstract: A seat rail for a motor vehicle seat includes a lower rail, which can be connected to a motor vehicle, and a spindle, which is arranged on the lower rail in a rotationally fixed manner by a spindle retainer. The spindle retainer is fastened to the lower rail by a fastening element extending through a fastening opening on the spindle retainer and a fastening opening on the lower rail. In order to provide a seat rail having a lower rail on which rotation of the spindle retainer is largely precluded, in particular in the event of a threaded floor connection extending through the spindle retainer, the fastening openings and/or the fastening element has a cross-section deviating from a circular shape, preferably a polygonal cross-section, in a connection section arranged in the region of the fastening openings.

  • Publication number: 20090272869
    Abstract: A longitudinal adjustment device of a motor vehicle seat has a left pair of rails (20), a right pair of rails (22) and an electric motor (24). An adjustment gear (32) is associated with each pair of rails (20, 22). The electric motor (24) has an output shaft (36) connected to the two adjustment gears (32). A motor retaining plate (42) is connected to a seat rail (26) of the left pair of rails (20) and to a seat rail (26) of the right pair of rails (22), receives the electric motor (24) and has a longitudinal direction. The motor retaining plate (42) forms a guide for the output shaft (36) of the electric motor (24), extends parallel to the longitudinal direction of the motor retaining plate (42) and is connected to the adjustment gear (32) of the left pair of rails (20) on one side of the electric motor (24) and to the adjustment gear (32) of the right pair of rails (22) on the other side of the electric motor (24).
