Abstract
Within a housing 4, the hinge includes a fixed cheek plate 1 and a moving cheek plate 2, one secured to the seat proper and the other secured to the seat back. Slugs 5 are mounted to move radially in grooves 7 of the stationary cheek plate and can hold the hinge in position by their outwardly directed sets of teeth 6 engaging in an inwardly directed set of teeth 3 of the moving cheek plate. The user can move the slugs by means of a lever and a central cam 8. The moving cheek plate 2 includes a set of notches 20 concentric with the set of teeth 3 and having a notch pitch that is equal to a multiple of the locking pitch of the set of teeth 3; at least one of the slugs 5 has a tooth 12 suitable for engaging in the set of notches 20 so as to enable the outwardly directed set of teeth 6 of the slug 5 to mesh in the inwardly directed set of teeth 3 of the second cheek plate 2, thereby obtaining a notch pitch that is considerably greater than the locking pitch. The hinge is applicable to adjusting the inclination of the seat back of the back seat of a car.
