Patent number: 9623768Abstract: 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.Type: GrantFiled: July 5, 2012Date of Patent: April 18, 2017Assignee: C. Rob. Hammerstein GmbH & Co. KGInventors: Robert Landskron, Thorsten Schürmann

Patent number: 9358902Abstract: 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.Type: GrantFiled: July 5, 2012Date of Patent: June 7, 2016Assignee: C. Rob. Hammerstein GmbH & Co. KGInventors: Robert Landskron, Thorsten Schürmann

Patent number: 9266448Abstract: 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).Type: GrantFiled: October 30, 2012Date of Patent: February 23, 2016Assignee: IMS GEAR GMBHInventors: Daniel Urban, Robert Landskron, Arif Karadag, Wolfram Hofschulte, Fred Krimmel

Patent number: 9242579Abstract: 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.Type: GrantFiled: November 29, 2011Date of Patent: January 26, 2016Assignee: C. Rob. Hammerstein GmbH & Co. KGInventors: Axel Speck, Daniel Urban, Robert Landskron
