Abstract: A device for absorbing energy by deformation, in particular for a motor vehicle seat, in the event of an impact, the energy absorption device comprising: a plate of substantially constant thickness comprising at least a first cutout and a second cutout which are separated by a bridge; and a rod extending through the first cutout wherein the bridge comprises a collar having, at least locally, a thickness greater than the thickness of the plate.

Abstract: An automobile vehicle seat includes a seat pan adjustable in height in relation to a support frame attached to the floor of the vehicle and an attachment point for a seat belt attached to the seat pan. A cable element is attached by one end to the support frame and the seat pan includes locking means adapted to allow the cable to slide during the voluntary variations in height of the seat pan in relation to the frame or, alternatively, to block the cable element by jamming during a high deceleration so as to prevent the seat pan from moving up in relation to the support frame.

Abstract: The structure of the seat proper of a vehicle seat comprises: a frame for a seat proper, the frame including a side cheek plate; and a coupling system comprising a link mounted to pivot on a base to enable the seat proper to move at least vertically relative to said base. The coupling system has a first latch surface. The seat structure further comprises an anchoring element provided with a second latch surface. The anchoring element is mounted to move on the cheek plate between a locked position and an unlocked position.

Abstract: A seat comprises a base assembly adapted to be fixed to the body of the vehicle, an articulated support assembly comprising front and rear support links for a seat cushion of the seat each of which has two ends articulated about axes which are respectively fixed relative to the seat cushion and to the base assembly, devices for adjusting the angular position of the support links relative to the seat cushion, and devices for controlling the position of a seat back of the seat relative to the seat cushion. The control devices comprise a convex or concave articulated quadrilateral, which has four corners, a first corner is connected to the seat cushion and the second and fourth corners are connected to the seat back.

Abstract: A seat for a motor vehicle has a seat with two side flanges mutually joined by a transverse tube. An anchoring wire for securing an element designed to be placed on the seat is joined at two ends to a flap extending in the vicinity of the transverse tube. Extending between the two ends is an open loop and a fixing section. The anchoring wire is deformable under the action of a strong force exerted on the fixing section, causing the loop to contract around the tube and transmit the force to the tube.

Abstract: A method of making a vehicle seat in which the strength member of the back has a first upright connected to the strength member of the seat proper by a hinge mechanism, a second upright that is not as strong as the first and that is hinged to the strength member of the seat proper, and two horizontal cross-members, the two cross-members and the top portion of the second upright being constituted by a tube folded into a general U-shape and of section that varies along its length. The method includes a step which consists in imparting the final shape to the tube by hydroforming, starting from an initial tube of substantially constant section.

Abstract: A device for operating, in the event of a shock, to lock the adjustable seat-raising mechanism (5) interposed between the base (1, 2) and the seat proper (3, 4) of a vehicle seat, the device comprising a scissors linkage constituted by two links (6, 7) pivotally mounted to each other about an axis A, the first link (6) also being pivotally mounted about an axis B linked to the base, and the second link (7) also being pivotally mounted about an axis C located behind the first axis and linked to the seat proper, a circular sector (8) having a rough cylindrical surface (9) is centered on the axis A and is secured to the first link (6), a flyweight (10) is suspended from the axis C and includes a rough cylindrical bearing surface (11) that is eccentric and that is suitable for co-operating with a wedging effect with the cylindrical surface of the sector, and a spring (12) is interposed between the seat proper and the flyweight and urges the flyweight rearwards so long as it remains in its rest position, and forwa

Abstract: An adjustable seat framework includes two frames articulated to one another, termed respectively first and second frames, joined by pivots, the first frame including at least one guide slot and the second frame including at least one associated operating slot, the associated guide and operating slots emerging in neighboring parallel planes and extending longitudinally in non-parallel directions, the adjustable framework further including, for each set of associated guide and operating slots, a roller which penetrates into said slots. An operating mechanism is provided for shifting the roller along the guide slot, which causes the rotation of the second frame about the pivots.

Abstract: The vehicle front seat comprises a seat proper (12) mounted on a base (10) by means of two oblique rods (14 and 15) and a back (13) pivotally mounted firstly about an inclination adjusting axis (6) and secondly about an axis (7) for folding the back down forwards, which axis is secured to the base. The bottom axis (4) of the front rod is connected to an axis (5) secured to the base via the short side (16) of a rigid triangle (T), a long rod (20) is pivotally mounted firstly about an axle (8) secured to the triangle and secondly about an axis (9) secured to the back, and a fourth rod (19) interconnects the two hinge axes (6 and 7) of the back.
