Abstract: Safety system for a filter pipe for filling a tank, in particular a fuel tank, the filler pipe including a pipe head suitable for receiving a delivery nozzle, the system including a valve which is mounted in the pipe head and is able to swing, between closed and open positions, about a swing axis essentially tangential to the periphery of the valve. The valve is kept closed outside the filling periods by a prestressing means and is swung open by a force exerted by a free end of the delivery nozzle against a contact face of the valve during the nozzle insertion into the filler pipe. In some embodiments, the valve is for closing off tightly a capless filler pipe, and includes, on its contact face, a stop device designed to allow the insertion of a suitable delivery nozzle into the filler pipe, and not of an unsuitable nozzle.

Abstract: A screen wiper apparatus, especially for a motor vehicle, is of the kind comprising a wiper arm which carries at least one wiper blade and which is mounted pivotally about a pivot axis on a drive head for the arm. Torque applying means, coupled between the drive head and the wiper arm, apply a wiping torque to the latter, and include at least one spring which applies a substantially constant nominal torque to the wiper arm. The torque applying means includes at least one complementary spring for applying a load to the wiper arm wherein that the algebraic value of this load is adjustable in such a way that the value of the wiping torque can be increased or reduced as a function of at least one operating parameter of the vehicle.

Abstract: A screen wiping apparatus comprises a wiper arm which carries at least one wiper blade. The wiper arm is articulated about a pivot axis on a drive head for driving the wiper arm in oscillating movement. A substantially constant wiping torque is applied to the wiper arm by a spring. The apparatus also includes means for applying a complementary torque to the wiper arm so as to modify the actual wiping force applied to the wiper blade. This complementary torque applying means includes an actuator having an output member, which is coupled to the wiper arm through a connecting member. The connecting member includes a working surface which cooperates with a complementary torque transmitting member, typically in the form of a lever, which is coupled to the wiper arm and which is pivotable with respect to the latter against the action of a loading spring.

Abstract: A screen wiper for a motor vehicle windshield comprises a screen wiper arm which is articulated about an articulation axis (X--X) on a drive head for driving the wiper arm. The wiper includes a cam connected to the drive head and a cam follower element which is connected to the screen wiper arm and which is displaced along the cam profile as a function of the relative angular displacements between the wiper arm and the drive head about the articulation axis (X--X), so as to apply to the arm a complementary torque such as to cause the value of the wiping torque to vary.

Abstract: A lock mechanism is provided with a housing having a closable flap pivoted thereon. The flap carries a key releasable lock cylinder equipped with locking elements and a locking bolt slidable under the action of a return spring. The locking bolt comprises a shoulder cooperating with a stud mounted on a cam plate which pivots to bring the bolt into the open position against the action of the return spring, whereby the bolt is disengaged from a fixed abutment. The cylinder and cam plate can occupy a locking position (v) in which the locking elements are resiliently urged into a locked position within locking grooves formed in the closable flap so that the stud locks the bolt. When the cylinder and cam plate are moved to a second position (F) angularly displaced from the locking position (v) the stud frees the locking bolt so that the bolt can move for the purpose of locking or unlocking the flap whether or not the key is present in the lock mechanism.
