Abstract

1372808 Adjustable backrests AUTOMOBILOVE ZAVODY NARODNI PODNIK 25 May 1972 [26 May 1971] 24595/72 Heading A4J [Also in Division E2] In a vehicle seat in which the inclination of the backrest is continuously variable by relative rolling movement between two unequally toothed gears 1, 2, all the teeth of the two gears are always in mutual contact, have a sinuous profile and the rolling movement is effected by rotation of a drive shaft 3 passing centrally through one of the gears and eccentrically through an aperture in the other of the gears. The drive shaft has opposed recesses 11 in which are fitted segments 4 which engage the edges of the aperture in the other of the gears to cause rolling movement on rotation of the drive shaft through a hand wheel 5. The gears may have a trochoidal profile.
