Positioning and blockage device of a seat back armature on a seat base armature mounted automatically in a vehicle

摘要

Each fixation member is mounted on a mechanism for setting inclination of the seat back and is formed of a casing so shaped to receive a dagger fixed to each lower end of the seat back armature. The dagger is held within the casing by being wedged with assistance of a part made of a central serrated roller and two lateral smooth extensions of smaller diameters enabling the roller to rotate freely inside openings formed in the casing and to be pushed by at least one spring for wedging the roller between the dagger and said casing.
