Abstract: The invention relates to an exhaust element (10) of a motor vehicle with an internal-combustion engine. It includes a main exhaust pipe (16) and a bypass (18) mounted in parallel with the main exhaust pipe (16). The bypass (18) includes a heat exchanger (20). Moveable means (28) for shutting off the main pipe (16) and moveable means (30) for regulating the cross section offered for the gases to pass in the bypass (18) are arranged in the exhaust element. It further includes mechanical means (32) for synchronizing the means (28) for shutting off the main pipe (16) and means (30) for regulating the cross section for the gases to pass in the bypass (18), under the control of a single actuating element.

Abstract: A method for manufacturing a steering wheel central pad having a skeleton (1) provided with an open dish (2), for receiving an inflatable bag in a folded state, and with a soft covering (5). At least the inflatable bag (3) in the folded state is placed in the dish. The opening of the dish (2) is closed off using a sealing material (4) which can tear when the bag inflates. The skeleton, together with its dish (2) provided with the bag (3) and with the sealing material (4), is placed in a mold for manufacturing the soft covering by injection of plastic. Then, plastic is injected into the mold in order to form the soft covering (5).

Abstract: This assembly, including a support structure provided with two flanges, a steering shaft including two portions, one carrying the steering wheel and the other connected to the rest of the steering mechanism and which are mounted telescopically one in the other, this shaft being capable of rotating in a body pivoting between the two flanges and including two portions which can be moved slidingly one in the other, one (7a) of them including a device for rotationally guiding and for axially blocking the shaft portion which carries the steering wheel, and the other being articulated between the flanges, and mechanisms with gear motors for adjusting the angular and axial positions of the steering wheel, which mechanisms are adapted to interact with the support structure and the body portion (7a) associated with the shaft portion which carries the steering wheel, is characterized in that the adjusting mechanisms have a structure (14) for suspending the body portion (7a) which is articulated on the support structure

Abstract: This assembly includes a steering shaft (101) which can move in rotation in a column body (102) and includes an anti-theft bolt (104) mechanism (103) which can move between a retracted position and an active anti-theft position. The shaft includes two shaft portions (105, 106), one (105) carrying a steering wheel and the other (106) being connected to the rest of a vehicle steering mechanism. The portions are connected by a disengagable linkage mechanism (108) which can move, under the control of the anti-theft mechanism, between an active position for coupling the two shaft portions and a retracted anti-theft position freeing the two shaft portions from each other so that the shaft portion (105) carrying the steering wheel can rotate freely with respect to the other shaft portion (106). The corresponding end zones (105a, 106a) of the shaft portions are arranged one around the other, and the disengagable linkage mechanism (108) is mounted so as to move around the shaft portion carrying the steering wheel.

Abstract: The motor-driven pulsator comprises, inter alia, a turbine (10) having a distributor (11) and an air-agitating member (12), and an electric motor (20) having a casing (200), a shaft (210) and a connector (220). This motor-driven pulsator comprises a mounting arrangement (30) consisting of a passage (31) permitting the unrestricted introduction of the member (12) into the distributor (11), an orientation means (32) for fixing, as desired, the relative rotational positions of the casing (200) and of the distributor (11) and securing elements (33) for joining the distributor (11) and motor (20).

Abstract: The steering wheel comprises a central hub (10), a peripheral rim (20), and at least one substantially radial branch (30) interconnecting the hub (10) and the rim (20). The hub (10) and the rim (20) are metallic, the rim (20) is circular or substantially circular and the branch (30) comprises a sleeve (31) which surrounds the hub (10) and a sheath (32) which at least locally covers the rim (20) and is made from at least one synthetic material in the state of a semi-manufactured product moulded onto the hub (10) and rim (20).

Abstract: The rapid fastener is adapted to achieve a connection in the axial direction and in rotation of two elements and more particularly torque-transmitting shafts. It comprises at the end of one of the elements a socket (8) which is provided with at least one helical slot (14, 16) and on which is axially slidable a ring (18) defining at least one longitudinal slot which is laterally offset relative to the entrance (14) of the helical slot. The ring (18) is biased by a spring (24) toward the entrance of the socket (8). The second element has a stem (4) provided with a driving pin (6) which, in entering the helical slot, urges back the ring but is guided under the action of the spring (24) and the edges of the two slots toward the inner end of the helical slot and is then locked in this position without clearance.

Abstract: The filter comprises a body (10) defining a chamber (101) to which access is had through an opening (102) closed by a cover (103). The chamber is adapted to receive a filtering cartridge (20). The body (10) is made in two semi-shells (110, 120) which are united in a junction plane (100) extending across the chamber (101), the opening (102) for the passage of the filtering cartridge (20) being astride the junction plane (100). A positioning device (30) for the filtering cartridge is carried by the body (10) to permit the insertion or the removal of the cartridge (20) by a movement in translation in a direction substantially parallel to the junction plane (100) and the positioning and the retraction of the cartridge by a displacement in a direction substantially perpendicular to the junction plane (100). Application in automotive vehicle engines.

Abstract: The steering wheel, except for its central metallic hub (11), is made from a synthetic material charged with long fibres which is used in the semi-manufactured product state in the form of blanks shaped by stamping in a mould where the blanks are preferably charged edgewise.

Abstract: The winder, which is more particularly of the type comprising a spring-biased tightener and is automatically locked under the control of an inertia unit, comprises a strap hub mounted on a base to be rotatable about its axis and movable in a direction perpendicular to the axis. This hub carries journals engaged in bearings (50) which are directly or indirectly connected to the base by at least one element (51) which is preferably in the form of a deformable and relatively elastic small bar. Application in safety belts for automobiles.
