Abstract: An electric motor has brushes preassembled in casings on a brush holder plate. To keep the brushes in the casings as long as a collector of the motor has not yet been fitted, a retaining ring in front of the brushes is installed, this retaining ring being gradually replaced by the collector when the latter is fitted. The retaining ring is introduced into a specially provided space of an accommodating chamber in a bearing support, provided with a slot and thus resilient in a radial direction. Therefore, the ring may abut with preload on the outside walls of the accommodating chamber. Frictional engagement between the ring and the walls of the accommodating chamber is established, preventing rattling noise or wear as a result of movement of the retaining ring.

Abstract: An adjusting lever pivoted on the attachment part moves during operation of the windshield wiper along a cam of a fixed rocker arm and thus pivots the contact spring to vary the force with which the wiper blade is pressed against the windshield being cleaned as a function of the particular wiper angle. The section of the adjusting lever on the rocker arm side has a fork-like design in which each fork leg rests upon an axially positioned cam of the rocker arm.

Abstract: A drive bearing for a windscreen wiper system wherein two actuator rods for actuating two wiper arms are driven by a motor crank. The two bearings are concentrically nested one within the other thereby allowing the driving forces of the two rods to extend in one plane. Other features include the association of the individual bearing elements to the actuator elements, and the design of the bearing faces.

Abstract: In a windshield wiper drive for a vehicle, the wiper spindle performs a rotational movement to-and-fro. In order that the inversion of motion does not take place all of a sudden but in a cushioned manner, a part-pinion with a pinion gap is realized when one tooth of the part-pinion is engaged by a cushioning stop member of a spring element. Reciprocally, another tooth strikes against an associated stop member shortly after the inversion of motion. The spring element is elastically deflected in the final phase of the rotational movement and thereby cushions the part-pinion. The spring element is preferably fastened to the gearing cover.

Abstract: An electric motor, in particular an electric small-size motor for driving windshield wipers on motor vehicles including a cup-shaped motor housing, a gear housing closing one front side of the motor housing by an end shield and having a cup-shaped section for receiving gearing elements and a cover closing the cup-shaped section of the gear housing, a holding device for an electric component positioned in a pocket of the cup-shaped section of the gear housing, in particular a holding device for at least one noise suppressor as coil, capacitor or diode, which electric component is connected in an electrically conductive way with a carbon brush arranged in the motor housing.

Abstract: A switch particularly for steering columns of automobiles for the selective operation of both light circuits and windshield wiper and washer circuits comprises a U-shaped spring contact having a first spring contact portion in a first plane and a second spring contact portion in a second plane. The switch includes a lever which is pivotal in both the first and second planes and which carries a rod member which may be engaged with the spring first portion to deflect it into engagement with a fixed contact for example for actuating a windshield wiper washer fluid supply circuit and which may be engaged during its pivotal movement for example in a vertical direction to move the spring second portion to engage a fixed contact which for example may operate a by-pass light circuit. The double spring contact actually includes the first spring portion which extends substantially vertical and at right angles to a horizontal portion.
