Abstract: A vehicle seat includes a seat part and a backrest. The backrest has a first axis of rotation and is rotatable about the first axis through at least 90° from a normal position into a loading position. The backrest has pivoting means and is transferable into an armrest position by the pivoting means. A predominant part of the backrest is mounted higher in the armrest position than in the loading position.

Abstract: A differential unit comprises a differential carrier (12) supported in a housing (1) for rotation; output elements (16, 17) differentially rotatable relative to the carrier and connected to respective output shafts, differential gears connecting the output elements, and a friction assembly comprising a number of plates (22) rotationally fast with one element of the differential interleaved with a number of plates (24) rotationally fast with another element of the differential, the friction plates being axially loadable into frictional engagement with one another to restrict the differential rotation of the output elements. The friction plates are loadable by an actuating mechanism comprising an abutment ring (54) fixed in the housing and an actuating ring (28) movable angularly and axially relative thereto, with cam surfaces provided by circumferentially extending variable depth grooves (47, 48) in the rings with balls (49) therebetween engaging the grooves.
