Patent ID: 7090299

Claim:
A device for adjusting the inclination of the back part of a motor vehicle seat having a device part ( 2 ) connected to the seat part and a device part ( 3 ) connected to the back part, which can be swiveled counter to each other about a pivot axis ( 14 ), whereby both device parts ( 2 , 3 ) have parts of gearings ( 4 , 5 ) forming a swash mechanism, which roll on each other under the action of eccentric elements ( 11 ) rotatable about the pivot axis ( 14 ), which have an eccentric ring ( 12 ), on which two mirror-image wedge segments ( 13 ) lie zonally covering it, which are urged away from each other by a spring element ( 15 ) abutting its front surface ( 13 . 3 ) in the sense of an increase of eccentricity (e), and that carrier elements ( 21 ) are arranged between the other front surfaces ( 13 . 4 ) of the wedge segments ( 13 ) for loading the wedge segments ( 13 ) against the force of the spring elements ( 15 ), whereby the eccentric elements ( 11 ) bear a device part ( 2 ), while the other device part ( 3 ) bears the eccentric element ( 11 ), characterized in that in the zone of the other front side ( 13 . 4 ) of the wedge segments ( 13 ) a radial stop surface ( 31 . 1 ) is provided thereon, which is associated with a radial stop surface ( 30 . 1 ) of the eccentric ring ( 12 ), whereby the alternating stop surfaces ( 31 . 1 , 30 . 1 ) are separated from each other prior to introduction of a displacement in the displacement direction, and when introducing a displacement, the carrier element ( 21 ) loads one of the two wedge segments ( 13 ) depending on the displacement direction, so that at least the stop surface ( 31 . 1 ) of the loaded wedge segment ( 13 ) and the associated stop surface ( 30 . 1 ) of the eccentric ring ( 12 ) come into contact with each other and carry the eccentric ring ( 12 ) along.
