ABSTRACT:
An adjustable seat of a motor vehicle has a mounting arrangement at each of its lateral regions. The respective mounting arrangement includes an elongated carrier, a support rail which is connected to the seat proper and is displaceable longitudinally of the carrier, and a pivot which mounts the carrier, which extends in the front-to-rear direction, for tilting along a vertical plane. A drive and a driving section of a transmission are mounted on the carrier, the driving section including two pinions which are simultaneously driven by the drive and one of which meshes with a driven rack rigidly connected to the support rail, while the other pinion meshes with another driven rack which is provided at one side of an elongated slot in a support element for the seat proper and is curved having its center of curvature on the axis of the above-mentioned pivot. The drive and the transmission displace the seat proper in a proportionate and mutually dependent fashion so that each tilted position of the carrier has associated therewith a single position of the support rail with respect to the carrier. The two mounting arrangements at the two lateral regions of the seat are similarly configurated and the corresponding pinions at the two lateral regions are interconnected by shafts for rotation in unison.
