Abstract: A hinge mechanism comprising first and second connection members mounted to pivot relative to each other and having first and second circular locking bearing surfaces co-operating with respective ones of first and second locking shoes that are part of the slugs so as to hold the first and second connection members stationary, and a control device for putting the slugs in engagement with the first and second locking bearing surfaces while allowing the slugs to pivot to a certain extent about their own axes.

Abstract: A hinge mechanism for a vehicle seat, said hinge mechanism comprising first and second cheek plates mounted to pivot about a common pivot axis, N locking members, each of which is provided with a second set of teeth, N guides secured to the first cheek plate, and a control device adapted to place the N locking members either in an active position, or in a retracted position, (N-1) guides being disposed in a manner such that the (N-1) locking members move along (N-1) respective axes of displacement that coincide with (N-1) radial directions, the last guide being disposed in a manner such that its locking member moves along an axis of displacement that is parallel to and offset relative to a radial direction that intersects the pivot axis.

Abstract: Vehicle seat comprising a cushion and a backrest pivoting with respect to the cushion about a horizontal pivot axis by means of an articulation between a range of erect positions of use, a folded-flat position and an intermediate folded-down position. This seat comprises a first, a second and a third control member connecting the cushion to the backrest, one of the first, second and third control members being distinct from the other two.

Abstract: A system for locking a first element with a second element, the system including a control member fitted on the first element and suitable for being actuated by a user in a direction that is substantially rectilinear and perpendicular to a pivot pin of a latch designed to co-operate with an anchor member fixed on the second element. The control member further includes a housing for receiving a finger of the latch while the latch is in the locked position so as to prevent the latch from pivoting about the pivot pin.

Abstract: A hinge joining system for an automobile seat includes a seat back flange and a seat pan flange. A hinge mechanism is attached to one of the flanges. An assembly fastener component is connected to the hinge mechanism and passes through an opening in the selected flange, the opening including a raised tapered collar. A thrust component is connected to the assembly fastener component, the thrust component having a bore for radially gripping the raised tapered collar and axially pressing the collar against the selected flange. The assembly fastener component has a tapered male section fitting into the tapered collar, and the bore of the thrust component is also tapered for gripping the tapered collar between the bore and the tapered male section when the thrust component is pressed against the selected flange.
