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 configur…
