Abstract

An irreversible adjustment mechanism comprising a casing, a pivotally-mounted lever urged resiliently towards a rest position, a pivotally-mounted intermediate member connected to the lever via a drive stage adapted to move the intermediate member only when the lever moves away from its rest position, a fixed ring, an outlet member co-operating with the ring to define hollow wedge-shaped spaces facing in opposite directions and receiving clamping bodies which are urged apart and which are flanked by two fingers that are part of the intermediate member. The casing comprises a base and a cover that are made of sheet metal and that are crimped together.
