  • Patent number: 7971312
    Abstract: The invention relates to a connecting element (22) for hingedly connecting a wiper blade (10) to a wiper arm, said wiper blade (10) having a wiper strip (12) and at least one sprung blade (20) inserted into the wiper strip (12). Said sprung blade projects beyond the wiper strip (12) in the area of the connecting element (22) and is enclosed by guide rails (30) that are interlinked by at least one spring clip (34) and secured in the longitudinal direction of the wiper blade (10) by at least one locking element (38) which laterally engages with a recess (28) of the sprung blade (20).

  • Patent number: 7644483
    Abstract: The invention relates to a method to manufacture a wiper blade (10) as well as a device to perform the method and a wiper blade (10) that is manufactured accordingly, wherein the wiper blade (10) features at least a basic body (56) featuring a wiper strip (24) and a supporting element (12). According to the method, the basic body (56) is supposed to be positioned in a holding device (58) in such a way that a clearance (63) remains between the supporting element (12) and holding device (58) at least in areas. The wind deflector strip (44) is gripped, at least one claw (46, 48) formed on the wind deflector strip (44) is threaded on the supporting element (12) and the wind deflector strip (44) is placed over the supporting element (12).

The guide rails (30) and the spring clip (34) are produced from a plastic material. The invention is characterized in that the connecting element is composed of a plastic securing part (26) and a metal bearing part (24), the securing part (26) being adapted to laterally enclose the sprung blade (20) with its guide rails (30) and having front walls (40) at its ends that project outward beyond the contours of the guide rails (30).

  • Patent number: 7464433
    Abstract: A wiper blade is proposed, which is used to clean windows, in particular of motor vehicles. The wiper blade is arranged with a rubber elastic wiper strip (24) on the one band surface (22) of a band-like, long-stretched-out, elastic supporting element (12) and can be placed on the to-be-wiped window (14). The other band surface (16) of the supporting element is covered by another component (40) of the wiper blade (10), at least in sections, and this covering part is provided with claw-like projections (54) arranged in the longitudinal direction of the wiper blade, which grip under holding edges (38) of the supporting element. A particularly tension-neutral and easily mountable wiper blade is achieved if the covering part (40), manufactured of an elastic plastic, is provided with an armoring (60) in the area of its projections (54) whose strength is greater than the strength of the plastic used for the covering part.

  • Patent number: 6831381
    Abstract: In an electrical drive mechanism, in particular for motor vehicles, having a commutator motor (14) disposed in a housing (10), which commutator motor (14) has a rotor shaft (17) with a commutator (22) non-rotatably supported on it and has a brush holder (30) affixed to the housing (10), and having a bearing (25) disposed in the vicinity of the commutator (22), which bearing has a bearing bush (34) that encloses the rotor shaft (17) with rotary play and a bearing seat (35) that contains the bearing bush (34), in order to achieve a simple embodiment for the bearing (25), a clamping member (37) is formed onto the brush holder (30) of one piece with it, which clamps the bearing bush (34) in a frictionally engaged, axial fashion in the bearing seat (35) formed in the housing (10) (FIG. 1).
