摘要:
An apparatus (10) for wiping a window (12) has a wiper (16), a first track (70) substantially parallel to at least a portion of the window and a second track (76) substantially parallel to and displaced from the first track. A first motorized drive wheel (24) is provided for driving the wiper along the first track in a first direction and a second motorized drive wheel for driving the wiper along the second track in a second direction, opposite to the first direction, so as to wipe the window. The wiper is preferably designed to reduce drag-back of water across the window. In a preferred embodiment, curved connecting tracks (82, 84) connect between the ends of the first track (72, 74) and the second track (78, 80) so as to form a closed loop track. A single motorized drive wheel is used. The single motorized drive wheel may be driven by a motor (86) rotatably associated with the wiper, or through a flexible drive cable (138) by a remotely mounted motor (140). Other embodiments use a single substantially linear track in combination with a motor running unidirectionally.

A vehicle comprise a window wiper device (5) having a brush (7) angularly movable between a first and a second position and actuator means (10, 14) to cause the angular motion of the brush (7) from the first to the second position. The actuator means (10, 14) comprise an active element (11) obtained at least in part with a shape memory material, as well as means (14) for cyclically causing the heating of the active element (11), so that the active element (11) passes from a respective extended configuration to a respective contracted position and consequently causes the angular motion of the brush (7) from the first to the second position.

The invention relates to a method for controlling a wiper for wiping the windscreen of a motor vehicle, said wiper carrying out a movement on the screen between two reversing positions. The speed of the wiper in the reversing position is equal to zero and in addition, the acceleration of the wiper in said reversing position is likewise substantially zero, i.e. less than or equal to 6 rad/s2. Preferably, the acceleration adopts the value zero in the reversing position.

A wiper driving apparatus comprises: a driving gear (12) driven by an electric motor (31), for driving a wiper; a clutch member (15) so rotatably provided as to rotate together with said driving gear (12) only in a driving direction of said driving gear (12); a first and a second electrically-conductive plate (24,25) constituting a switch for opening and closing an electric circuit of said motor (31); and a first and a second moving-contact segment (16,17) which are rotated relative to said first and said second electrically-conductive plate (24,25) respectively while brought into a slidable contact therewith respectively. A driven engaging projection (19) of said clutch member (15) extends towards said driving gear (12), and is disposed in a position differing in phase from a contact position by an angle of at least 90 degrees, preferably by an angle of 180 degrees, in which contact position a contact point (21) of said second moving-contact segment (17) is brought into an electrical contact with said second electrically-conductive plate (25).

Apparatuses and methods for removing ice from a windshield. A windshield wiper includes a wiper assembly, a scrubber assembly, and an engaging assembly. The wiper assembly includes a wiper support structure and a wiper blade attached to the wiper support structure. The scmbber assembly includes a scrubber support structure, an elongated scrubber element and a motor. The scrubber element is movably attached to the scrubber support structure and extends between a first end and a spaced apart second end along a central longitudinal axis. The scmbber element can have a hardness value sufficient to remove ice from the windshield. The motor is mounted to the scmbber support structure and is engaged with the scrubber element to move the scrubber element to remove ice. An engaging assembly can be coupled with the wiper assembly and the scmbber assembly to raise and lower the scrubber assembly with respect to the wiper assembly.
摘要:
A wiper motor (11) which can prevent an impact force from greatly acting on attaching parts is provided. A gear cover (40) formed in a substantially inverted y-plate shape is fastened to an opening of a gear case (21) of the wiper motor (11) used in a rear wiper device so as to cover a worm reduction gear (22) and a crank device. A gravity center of a motor part and a gear part is disposed within an area of a triangle formed by a first attaching part (41), a second attaching part (42), and a third attaching part (43), which are formed at three end portions of the inverted y-plate shape of the gear cover (40). The first attaching part (41) is disposed on an extension line of the rotation axis (12), and the rotation axis (12) is disposed at a position where a segment connecting the second attaching part (42) and the third attaching part (43) is divided into half. A wiper shaft (31) is disposed on an opposite side to the third attaching part (43) with respect to a segment connecting the first attaching part (41) and the second attaching part (42).
