Abstract: Hinge mechanism comprising first and second frames connected together by an adjustment device comprising a first set of gear teeth integral with the first frame and a first mobile toothed component engaging with the first set of gear teeth. The second frame comprises a second set of gear teeth, which interferes with the first frame when the torque applied between the first and second frames exceeds a predetermined threshold, in order to immobilize the frames rotatably in relation to each other.

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.

Abstract: The hinge mechanism (10) is attached to at least one of the seat back or seat pan flange (12, 14) by a joining system comprising at least one assembly component (3) connected to the hinge mechanism and passing through a hole in the flange. The hole features a raised collar (4) which is tapered, at least in part, and is radially gripped in a hole (52) made in a thrust component (5) connected to the said assembly component such that it is pressed axially against the flange. The assembly component (3) features a tapered male section (32) of appropriate diameter to fit into the tapered collar (4) when the hinge mechanism is assembled with the flange, and the bore (52) of the thrust component is also tapered so as to form a female tapered section capable of gripping the tapered collar between the said bore and male tapered section when the thrust component is pressed up against the flange.

Abstract: A pivot mechanism comprising first and second frames linked so as to pivot, in which locking members may co-operate with teeth on one of the frames in order to lock the mechanism, and a central cam which is urged toward a rest position by a single spring, the spring being rolled in an indentation of the second frame.

Abstract: A pivot mechanism comprising first and second frames linked so as to pivot, in which locking members may co-operate with teeth on one of the frames in order to lock the mechanism, and at least one stop member which is joined to the second frame and which is arranged so that the locking member abuts at an angle against said stop member if the pivot mechanism is subjected to a pivot torque in a first direction of rotation whilst the locking member is in its locked position: if this torque exceeds a threshold value, the stop member is displaced towards the over-locking member and pushes it against the teeth of the frame in order to lock it.
