Abstract: A system for locking a first element with a second element, the locking system comprising a plate and/or a latch including at least one deformable zone adapted to deform in the event of one of the first and second elements being subjected to a predetermined impact, so as to cause a portion of the plate and a portion of the latch to move towards each other sufficiently for the portion of the latch to come into abutment contact against the portion of the plate, thereby preventing the latch from pivoting towards the unlocked position.

Abstract: A vehicle seat comprising a seat back mounted to pivot on a seat proper by means of first and second hinges, each of which is made up of two pivotally-mounted cheek plates that can be locked by slugs controlled by a rotary cam so that they are caused to come to mesh in a fixed set of teeth. The cams of the two hinges are connected together via a lost motion mechanism, and the fixed set of teeth of one of the hinges has truncated teeth, each of which forms a flat.

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 outlet member is secured to a coupling shaft which is guided in rotation by a ring held by catches of the casing that pass through recesses in the inlet member while leaving a central portion of the inlet member visible, on which portion an actuating handle may be fixed.

Abstract: An articulation for an automobile seat includes a mobile flange having an inner toothing, a fixed flange having an inner toothing for cooperating directly with the mobile flange and an eccentric means positioned between the mobile flange and the fixed flange for biasing aa articulating element. The eccentric means including a driving axis provided with a snug and a pair of discs rotatable about the axis relative to one another. Each disc having a central recess and an arc-shaped window. The central recess having a hollow housing extending outwardly for receiving the snug of the axis. A resilient member is positioned within the arc-shaped windows of the discs and bears against bearing surfaces provided at the ends of the windows. When the two discs are spaced apart from one another by the eccentric means, the articulation ensures the clearance take-up and the irreversibility of the articulation.

Abstract: A vehicle seat in which the backrest is controlled in terms of rotation about an axis of pivoting by an adjustment mechanism which includes an input shaft, a fixed flange integral with the framework of the seat cushion, and a mobile flange which can rotate about an axis parallel to the axis of pivoting of the backrest but offset therefrom. The mobile flange is integral with a pin which penetrates an oblong slot in the framework of the backrest so as to be able to rotate inside this slot and so as to be able to slide radially with respect to the axis of pivoting of the backrest. This pin is further from the axis of pivoting of the backrest than from the axis of rotation of the mobile flange, so that the adjustment mechanism can withstand low torques.

The outer profile member comprises an upper plane portion edged in a symmetrical manner with respect to a median vertical axis X-X1 by first guiding paths extended by connecting parts linking together the first guiding paths with second guiding paths. Sliding or rolling members are inserted both between the first guiding paths and the arcuate paths and between the arcuate parts and the second guiding paths.

Abstract: An adjusting mechanism for the back portion of a seat comprises a fixed circular flange attached to an armature of the sitting portion of the seat. The fixed flange has a cup-shaped recess and cutouts spaced at 120.degree. from one another. Each cutout contains a block with an outer toothing. The blocks are resting on block-pushing members each provided with a finger facing the mobile flange. The block-pushing members rest on a cam with three steps. The fingers of the block-pushing members cooperate with a release ring housed inside the mobile flange and having three projections provided for pushing the block-pushing members toward the center of the adjusting mechanism when the cam is pivoted in a direction for moving the back portion of the seat onto the sitting portion.
