Abstract:
The invention relates to a direct current motor control circuit. The invention also relates to the use thereof in a windscreen wiper system for vehicles. An MOS FET transistor with an anti-parallel diode (M3) is serially mounted on the braking system (M2) of the control circuit.
Abstract:
A wiper connector for a motor vehicle intended for the connection and articulation between a wiper arm and a component of a wiper blade is engaged longitudinally from rear to front inside the front end of the arm, which is curved longitudinally towards the rear in the form of a U. The wiper connector includes at least one elastically deformable element for securing the connector in the engaged position inside the front end of the arm and two longitudinal vertical flanks, which are designed to be received between two lateral wings of the blade component. The wiper connector is locked in the engaged position in the arm by a safety fastener mounted so as to be able to move between a closed position, in which it extends with regards to the securing element in order to prevent its elastic deformation, and an open position allowing the disengagement of the connector from the arm.

Abstract:
A motor vehicle equipment module having at least first and second components in which first and second fixing zones are designed to be fixed to a structural element of the vehicle with a common fixing element. The module includes links which link together the two components when the module is to be mounted on the vehicle structural element. An elastic element is axially interposed between the links and the second component. The links are interposed between the common fixing element and the structural element when the module is fixed on the vehicle.
Abstract:
A method and a device for the production of curved spring strip sections. A spring strip runs through a bending unit formed from three separate support points and a reverse bending unit, arranged in series, and formed from a fourth support point. Bent and reverse-bent spring strip sections are separated off from the spring strip in a separator unit. In order to achieve a compact construction for the device, the third support point of the bending unit and the fourth support point of the reverse bending unit are adjustable in position relative to the spring strip, by a controller with pre-set programs.
Abstract:
A motor vehicle equipment module includes a lock formed of a bolt received in a housing designed to be mounted on a support part and a striker designed to be mounted on a mobile part along a globally axial direction relative to the support part between an open position and a closed position wherein the bolt cooperates with the striker. When the module is delivered to be installed on the vehicle, the striker and the bolt are linked together by an intermediate plate for temporarily indexing the position of the bolt relative to the position of the striker and to facilitate mounting and fixing of the module on the vehicle.
Abstract:
A wiper arrangement for a windscreen of a motor vehicle having a screwless fixing device, which has at least three fixing members arranged at a distance from one another, two of which lie on a connecting line and the third of which is arranged at a distance from the connecting line, and which includes appropriate receiving devices, in which the fixing members can engage and at least one fixing member includes a thickened section for axial securing. The receiving device of the wiper arrangement includes a recess designed to complement the thickened section and in which the thickened section can be received in the manner of a snap-locking connection.
Abstract:
A motor vehicle screen wiper apparatus comprises a screen wiper mounted on the upper end of a drive spindle, the apparatus including means for varying the inclination between the spindle axis and a reference axis which is substantially at right angles to the plane of the glass to be swept. The drive spindle is mounted for pivoting movement about at least one pivot axis, and the apparatus includes a cam mechanism which controls this pivoting movement of the drive spindle, so as to vary the inclination between the drive spindle axis and the reference axis as a function of the rotational position of the drive spindle about its own axis of rotation.
Abstract:
A motor vehicle screen wiper drive unit is a motorized reduction gear unit comprising a reduction gear train between a driving shaft, driven by a motor, and a driven shaft. The gear train comprises at least one worm fixed to the driving shaft and meshing with a first set of teeth of an intermediate gear wheel. The latter also has a second set of teeth meshing with a driven gear wheel which is carried by the driven shaft. The second teeth of the intermediate gear wheel, and the teeth of the driven wheel, are generally helical, being so oriented that the driven wheel exerts an axial force urging the intermediate gear wheel in a direction opposite to that in which the worm is urged by an axial force exerted on the intermediate wheel by the worm. The need for rigid abutment means for the intermediate wheel is thereby avoided.
