Abstract

A hinge for the back of a vehicle front seat comprises two fine adjustment mechanisms A and B having respective central cams and toothed slugs 7A and 7B, the mechanisms being disposed on either side of the seat and being controllable by a common handle 8, the hinge also has a single locking mechanism C with a latch that is controllable by a knob M, the locking mechanism being situated on the same side as the handle and allowing the back to be tilted down forwards. The cams are controlled by two colinear lengths of shaft 6A and 6B that are free to move angularly relative to each other and the first of which is connected to the handle. These lengths are respectively connected to two levers 17 and 18-19 that bear angularly against each other, the lever 18 which is not connected to the handle being connected by a cable 20 to the latch in such a manner that the mechanism B that is further from the handle is controlled both by the handle and by the knob.
