  • Patent number: 9441705
    Abstract: In the case of a holder for fastening a unit (2), in particular a pump, to a motor vehicle, with an annular damping element (1), the inner region of which is provided for accommodating the unit (2) and which has, on the outside, a block-shaped fastening part (4), under the upper side (14) of which a plate-like insert (8) which is designed for local reinforcement of the damping element (1) is arranged, it is proposed according to the invention that two opposite edges of the insert (8) each have a wing (11) running into the damping element (1). This produces an increased, but limited local minimum rigidity of the holder.

  • Patent number: 7559110
    Abstract: A wiper blade is suggested for cleaning window panes in motor vehicles. The wiper blade (10) has an elongated rubber-elastic wiping strip (20) which can contact the window pane (18) and is provided at both of its longitudinal sides (30) with open-edged longitudinal receiving grooves which are arranged in a plane approximately parallel to the window pane and in which a strip-like, elongated, resilient carrying rail (12) is accommodated in each instance. The inner edges of the carrying rail (12) which face one another contact a longitudinal web (36) of the wiping strip remaining between the grooves (32) and the two carrying rails (12) are secured in their receiving grooves transverse to their longitudinal extension by a holder which is arranged at the upper strip surface (13) of the carrying rails remote of the window pane.

  • Patent number: 6973698
    Abstract: A wiper device with a wiper blade for cleaning windows of motor vehicles, in which the wiper blade can be moved back and forth laterally to its longitudinal span by a driven wipe arm which can be connected to the wiper blade and loads the same against the window. The wiper blade has an elongated wiper strip that can be placed against the window and an elongated spring-elastic carrying element, which has a connecting unit for the wiper arm and is disposed parallel to the longitudinal axis of the wiper strip to distribute a contact force over the entire wiper strip length. A particularly effective and low-noise operation of the wiper system is achieved because the contact force of the wiper strip against the window is greater in its center section than in at least one of two end sections of the wiper strip.

  • Patent number: 6810556
    Abstract: The invention relates to wiper blades of various dimensions for windows of motor vehicles, with band-like, elongated, spring-elastic support elements (14), each for a respective wiper strip (22), which is associated with each wiper blade (10), can be placed against the window (12), and is disposed on the lower band surface (21) oriented toward the window, where in a longitudinal midsection of each support element, the upper band surface (15) oriented away from the window supports a wiper blade half (16) of a connecting device (18). In order to supply wiper blades of different dimensions with a single type of such a connecting device half and to thereby reduce the costs for the wiper blades, the widths (36) of the support elements in this longitudinal midsection are the same size independent of the other dimensions of these support elements.

  • Patent number: 6687948
    Abstract: A device is proposed which is used to wipe windows of motor vehicles. The wiping device has an oscillatingly driven wiper arm (12), guided on the motor vehicle, on whose free end, remote from the oscillation axis (16), a wiper blade (22) which is elongated transversely to the oscillation direction, that can be placed against the window (24) is releasably hinged via a connection device (26) that has coupling parts of the wiper arm and of the wiper blade, and the hinge axis (32) extends substantially in the oscillation direction (double arrow 18). In such a wiping device, an especially low-wear hinge is obtained if the wiping device has at least one support shoulder (72 and 96), fixed to the wiper arm and pointing toward the oscillation axis (16), with which a check shoulder (74 and 102) fixed to the wiper blade and pointing away from the oscillation axis (16) is associated.

  • Patent number: 6668419
    Abstract: The invention relates to a wiper blade (10) for motor vehicle windows. The wiper blade includes a rubber-elastic wiper strip (20) stretched out long in the manner of a band that can be placed against the window with a wiper lip, the two side walls of which each include a longitudinal groove (28, 30) which is situated in a plane that is basically parallel to the window (14) and has clearance from the window, so that a bridge (34) remains between the two grooves, and a spring (36 and/or 38) is accommodated in each longitudinal groove-that belongs to a spring-elastic carrier element (12) stretched out long in the manner of a band. Retention of the required flexibility of the wiper blade even with problematic window configurations is ensured when the distance (44) between the facing longitudinal edges (40, 42) of the two springs (36, 38) is greater than the width (46) of the bridge (34).

  • Patent number: 6588047
    Abstract: The invention is based on a wiper system with at least one wiper support (10,12,14,16), which, in a pre-mounted state, has a part (18) that is guided through a mounting opening (20) of a vehicle and is fastened to it. The proposal is made that while being mounted, the wiper support (10,12,14,16) rests against the rim of the mounting opening (20), tilts under the influence of gravity and as a result, is held in the mounting opening (20) with frictional, non-positive engagement and/or positive engagement.
