Abstract: A device for fixing the hub of an arm of a wind-screen wiper (2) on a pivoting axis (1) with locking elements (6, 7) for the arm on the pivoting axis (1), a cavity (32) which is created in the hub (2) and is provided with adjusting and angular positioning elements for the arm in relation to the axis (1), whereby the hub (2) rests on the base of a stop (3) which nestles on a radius of operation (4) of the said axis (1); the locking elements (6, 7) are adapted in such a way that they can be engaged in a locking or unlocking position, the adjusting elements includes a connecting ring (10) which is rotationally fixed to the axis (1) and accommodated in the cavity (32) of the hub (2) with a certain amount of play allowing for limited relative angular displacement between the connecting ring (10) and the hub (2) when the locking elements (6, 7) are in an unlocked position, whereby all relative displacement is prohibited between the connecting ring (10) and the hub (2) when the locking elements (6, 7) are in a locke

Abstract: A motor vehicle seat adapted to receive a safety belt includes a seating part and a back part on either side of an articulation zone. Each of the parts includes a frame with two arms abutting the articulation zone, the two arms forming respectively side members for the seat and vertical members for the back: the ends of the two arms of one of the parts and the ends of the two arms of the part are mounted each rotating via a pivot in a bearing. The pivot is borne by one part and the bearing by the other part, and an energy-absorbing element is provided between at least a pivot and its corresponding bearing.

Abstract: A coupling device for placing at one end of a shaft (21), comprising a hub (40) to be mounted on and axially locked relative to the shaft (21), the shaft (21) being surrounded by a hollow cylinder (34). The hollow cylinder (34) and the shaft (21) are locked in their relative adjusted angular positions by a locking washer (70) held against the front surface (35) of the hollow cylinder (34) by a locking screw (61) centered on the axis (20) of the shaft (21) axially holding the hollow cylinder (34) against the hub (40), the device being preassembled to form a sub-assembly.
