Abstract:
The invention relates to a drive mechanism (30) especially for a window wiping device (1) with an elliptical wiping motion, said device comprising a primary actuating axle (20), a rotary support (40), a fixed toothed wheel (50), at least one central toothed wheel (60), an output toothed wheel (70), and a secondary actuating axle (50), the toothed wheels (50, 60, 70) being engaged with each other and forming a two-stage gear system. The invention is characterised in that the rotary support (40) comprises two supporting elements (41, 42) that respectively carry the two stages of the gear system, and in that the two supporting elements (41, 42) can be arranged in relation to each other following at least two separate angular positions in which the toothed wheels (50, 60, 70) are effectively engaged.
Abstract:
The invention relates to a wiper mechanism (18) for a window panel (12) which is pivotable relative to the body (16) of the vehicle (10) between a closed position, and between an open position in which the window panel (12), comprising a shaft (22) for driving a wiper arm (24) in rotation around a rotation axis relative to the window panel (12), a motor reducer (26) comprising a driving shaft (36) which is capable of being coupled in rotation with the drive shaft (22) when the window panel is in the closed position, and means for locking (40) the drive shaft (22) in rotation relative to the plate (20), in a predetermined angular position, characterized in that the locking means (4) include a locking member (42) which is mounted movably relative to the plate (20), between a position for locking the drive shaft (22) in rotation relative to the plate (20), and an unlocked position enabling the drive shaft (22) to rotate relative to the plate (20).
Abstract:
Wiper system for vehicle windows, in particular for vehicle windscreens, with at least one wiper shaft which is mounted in a wiper shaft bearing and can be driven by a wiper drive, with a wiper arm end which is fastened to the wiper shaft end protruding from a vehicle body, and with an axial securing element for securing the wiper shaft against axial displacement, wherein the axial securing element releases the wiper shaft for axial yielding in the event of the wiper shaft and/or the wiper arm end being subjected to an external application of force which exceeds a release force.
Abstract:
A method of protecting a reversible electric motor that includes an armature capable of rotating axially about itself between two angular end positions, the axial rotation of the armature undergoing a deceleration phase as each angular end position approaches, where the method involves determining a characteristic value of the deceleration phase, comparing this characteristic value to a predetermined threshold value, and applying a degraded operating mode when the characteristic value is far from the threshold value.
Abstract:
A device for supporting and attaching a wiper blade and a blade mounting thereof on a wiper carrier includes a connector including two halves connectable to each other and configured in a connected position to support and lock the blade and said blade mounting. Each connector half includes a projecting component configured to engage with a matching component, one on said blade and the other on said mounting respectively.
Abstract:
A drive arm for a wiper blade has a rear end portion configured to be fixed to a drive shaft of the arm in an alternating sweep movement about a roughly vertical axis, a free front end portion operable to carry the wiper blade, an intermediate portion of longitudinal principal orientation that is elastically deformable in a vertical longitudinal plane and that connects the rear portion to the front portion, and a stiffener for stiffening the intermediate portion flexurally in a horizontal plane. The stiffener has at least one first flexible longitudinal element that is fixed along a first longitudinal lateral face of the intermediate portion so that, when a transverse force is applied to the intermediate portion in a first direction, a longitudinal stress is exerted on the first reinforcing element.
Abstract:
The invention relates to an electromotive drive comprising an electric motor with a commutator that is located in a motor housing, in addition to gearing that is flange-mounted on the electric motor. In the drive, the armature shaft passes through an opening into the interior chamber of a gearing housing. A screening element is fixed onto the shaft to rotate with the latter. The screening element almost completely seals the opening against abraded carbon particles or dust from the brushes. The screening element also carries a control magnet that co-operates with a sensor of the motor control module.
Abstract:
The invention relates to a connector (10) for mounting a windshield wiper blade unit (12) on the front longitudinal end (14) of a windshield wiper arm (16), in which connector:the connector (10) is mounted sideways onto a coupling element (20) of the wiper blade unit (12) via a transverse rod (32);the connector (10) has a top transverse bar (38) for locking it transversely in the mounted position in which it is mounted on the coupling element (20);the front end (14) of the arm (16) is curved back to form a U-shape that is rearwardly open; andthe connector (10) has a body (28) around which the U-shaped front end (14) of the arm (16) is engaged, and two vertical longitudinal side cheek plates (30) which are interconnected by the body (28) and between which the front end (14) of the arm (16) is received;the connector (10) being secured dismountably to the front end (14) of the arm (16) by resilient interfitting engagement and/or by co-operation between complementary shapes;said connector being characterized in that the body (28) and the two vertical longitudinal cheek plates (30) form a single part.
Abstract:
The invention provides a wiping system of a motor vehicle glass panel, including a wiping blade assembly with a longitudinal main orientation, including a blade of the glass panel blade assembly pressure means on the glass panel, which exert a pression force on the rear end of the blade assembly, and where the pressure means exert on the blade assembly an additional force, where the additional force is produced so as to distribute the pressure of the wiping blade globally symmetrically with respect to the middle in the longitudinal direction of the blade assembly.
