  • Patent number: 5453671
    Abstract: The invention relates to an electromotive actuator with a housing for a central door locking system of a motor vehicle having a first slide adjustable by a first electric motor between two end positions. The first slide can be connected with a door lock of the motor vehicle independently of the end position and is preferably decoupled from the electric motor in the end positions, so that the first slide is manually adjustable between its end positions. Such an electromotive actuator is provided with a theft protection capability in the sense that, after a windshield of a motor vehicle is smashed in, an unlocking of the door by the inside locking handle is no more possible because the parts of the actuator are not actuated by operating the inside locking handle. Finally, an unlocking operation initiated from the outside is possible when the theft protection is put into operation.

  • Patent number: 5386090
    Abstract: An electric switch unit, in particular for the control of air conditioning units in automotive vehicles. The switch unit includes pushbuttons whose symbols are illuminated by light which is guided from a central source of light through a light-guiding member. The light-guiding member is composed of interconnected light-guiding bars to which projections are molded. From the projections the light exits toward the pushbuttons. The front faces of the projections are concavely curved, and as a result a uniform illumination of the symbol areas is provided. The light-guiding bars are furnished with totally reflecting surfaces, and as a result the total quantity of light incident upon them is reflected into the projections. The quantities of light exiting from each projection are equal. Due to the arrangement of a focusing lens at the transition of the light from the source of light to the light-guiding bars, a parallel beam of light is emitted into the latter.

  • Patent number: 5386165
    Abstract: In order to be able to completely eliminate the axial play of an armature spindle of an electric motor, especially for a windshield wiping system of a motor vehicle, even though conditions change over time, a prestressing member acted upon by a spring leg continuously presses against the end of the armature spindle. The prestressing member does not necessarily have to abut directly on the end of the armature spindle, but rather a cap is inserted onto the end of the armature spindle and non-rotatably fixed to the motor housing or a gear housing. An eccentric formed as the housing of the prestressing member abuts on the outside of the bottom of the cap. In an alternative embodiment, a mushroom shaped prestressing member having a mushroom head presses against the end of the armature spindle.

  • Patent number: 5326235
    Abstract: In order to connect a pump (1) with an electric motor (2) quickly and form-fittingly, a hollow, tappet-shaped stud (6) is formed onto the pot-shaped motor housing (7), specifically onto the bottom of the pot (10). The stud engages an insertion recess (5) of the pump. A driving eccentric (4) of the driven shaft (3) is connected with the pump during the assembly of the pump. If the inside of the tappet-shaped stud (6) is to receive the first motor bearing, a fit is needed at the inside as well as at the outside of the stud. If the motor housing (7) is made from deep drawn sheet metal, the double fit is only possible, if, when viewed in the circumferential direction, the cross section of the wall of the stud (6) is formed like a wave. This facilitates the use of a plastic cover (18) in connection with the sheet metal housing (7) and the avoidance of a carbon brush support plate.

  • Patent number: 5231730
    Abstract: A wiper blade for a windshield wiper system of motor vehicles is described, in which wiper blade a reinforcing rail is secured against longitudinal movement in its central area on the wiper lip. The securement is performed by a cam pressed from the blade and received in a recess of the reinforcing rail. The relative movement between the reinforcing rail and the rubber wiper strip, which cannot be prevented when bent windshields are being wiped, is thereby evenly distributed over the two ends of the wiper strip. This improves the wiping effect of the wiper blade in comparison to known models, where the reinforcing rail is coupled to one end of the wiper strip.
