Abstract: The latch structure comprises, on one hand, a case (1, 2) for the mechanism (6) of the latch structure and, on the other hand, a keeper (5) which is movable relative to the case (1, 2). The mechanism (6) is provided with a bolt (7) which is pivotable about an axis (8) perpendicular to the movement of the keeper (5) with which the bolt cooperates by a fork-shaped portion (24). An actuating lever (9) of the latch structure is adapted to allow the rotation of the bolt in the direction for releasing the keeper through a locking member (12) interposed between the bolt and the actuating lever. The locking member (12) is movable in one of two elements (7) consisting of the bolt and the actuating lever between a projecting position for rendering the two elements rigid with each other and a retracted position for allowing the free movement of rotation of the bolt relative to the actuating lever.

Abstract: A fan unit for cooling an internal combustion engine comprising a fan impeller associated with a coaxial channel for guiding the air travelling through said impeller and an electric driving motor of DC type. The channel is fixed to the ends of the blades of the impeller and rotates with the impeller and itself constitutes the rotor of the electric motor whose stator coaxially surrounds at least a part of the channel. The stator is rigid with a fixed shaft around which the impeller rotates. This fan unit has a high permeability when inoperative so that it is particularly adapted for use in an automobile vehicle.

Abstract: In this control box, a first switching device (R-1) is actuated when the operator acts on a selector (1) whereby he can choose, on one hand, the direction of the driving of the motor (9) and, on the other hand, by means of a brief or prolonged action, the driving speed of this motor. If the action is prolonged, the switching device (R-1) is inhibited by a second switching device (R-2) controlled by a timing circuit (27) which was initiated at the start of the action. This second switching device then supplies power to the motor (9) through a series resistor (18) so long as the selector (1) is actuated. Application in an electric window raiser of an automobile vehicle.

Abstract: The device comprises an electric motor having a planar airgap the rotor of which constitutes a flywheel capable of being coupled frictionally with a plate rigid with the shaft of the heat engine to be started. For this purpose, the motor is axially movably mounted in a case between an uncoupled position to which it is biased by a spring and a position in which it is coupled with the plate. The motor is brought to the latter position by the excitation of a clutch coil carried by the rotor and exerting a force of attraction between the rotor and the plate in opposition to the action of the spring. Owing to its small axial overall size, this device requires only a low electric power and may be adapted to mopeds.

The locking device is mounted on the support to pivot about a pivot axis and comprises at least one first abutment surface against which the bolt member is retained in the locked position. The first abutment surface is disposed in such manner in the locking device that a force exerted by the belt on the bolt member produces about the pivot axis a torque for releasing the bolt member. The locking device also comprises at least one second abutment surface, a stop member movably mounted in the support and a control member for moving and withdrawing the stop member. The second abutment surface is capable, under the action of said torque, of bearing against the stop member until it is withdrawn by the control member to release the locking device.
