Abstract

A mechanism for adjusting the inclination of a backrest of a vehicle seat includes two hinges each at one side of the seat and each including two hinge members respectively secured to the seat component and the backrest component of the seat and mounted on each other for tilting. Each of the hinge members has an internal gear annulus, the gear annuli of the two hinge members having the same diameter but different numbers of teeth. A support element is mounted for rotation in the space bounded by the gear annuli and has a cross-sectionally elliptical peripheral surface. An elastic band embedding a plurality of uniformly distributed pins is supported on the peripheral surface of the support member and meshes with both of the gear annuli at the region surrounding the major axes of the elliptical generatrices of the peripheral surface of the support member. The number of pins which engage via the band both internal gear annuli corresponds to the number of teeth of the annulus which has the smaller number of teeth.
