摘要:
A wiper arm pivot is rotatably mounted in a pivot holder fixedly securable to vehicle structure. The wiper arm pivot is telescopingly displacable in the pivot holder upon an impact load on one end of the wiper arm pivot. An energy absorption material has a gel state when disposed in the pivot holder and flows through one or more orifices from the pivot holder under impact forces causing telescoping movement of the pivot in the pivot holder absorption of the impact force on the pivot shaft. In another aspect, the energy absorption material is a liquid which is retained within the pivot holder by a releasable plug which is separable from the orifice under a predetermined impact pressure.

A motor bracket is attached at one end of a vehicle body so as to be able to slide, and is fixed at the other end to the vehicle body. And weak points are provided in the vicinity of a motor bracket fixing section. Weak points are also provided in the vicinity of a first fixing section of a first pivot holder. On the other hand, weak points are also provided in the vicinity of a second fixing section of a second pivot holder. Since the motor bracket slides and becomes detachable if the weak points are ruptured, it is possible to absorb an impact at the wiper motor. Since the first and second pivot holders are also detached if the weak points and weak points are ruptured, it is possible to improve the overall impact absorbing performance of the vehicle wiper assembly.

A visibility enhancement system for a CNC machine center that incorporates a windshield wiper assembly. The CNC machine center has a door with a window for viewing machining operations therein. The windshield wiper arm and its wiper blade are mounted on the inner surface of the window in the door. The windshield wiper assembly has structure on the outer surface of the door for reciprocally rotating the windshield wiper arm back and forth through a predetermined angle. The windshield wiper assembly has spring means for constantly pressing the wiper blade against the inner surface of the window. The windshield wiper arm has an adjustable length arm that allows different lengths of wiper blades to be used.

The invention relates to a wiper apparatus in which a pair of pivot axes are provided, one pivot axis at the central portion and the other pivot axis one side portion in the left and right direction of the window surface. In the invention, wherein the rod rush angle formed by a link arm, which rotates the pivot axes clockwise and counterclockwise, and a link rod can be made as small as possible. The second pivot axis at one side portion is disposed so that the plane, including the swinging locus, of the second link arm, that is coupled to the corresponding second pivot axis, and the axial line of the second link rod, in the lengthwise direction, are made roughly parallel to each other.

A windscreen wiper device is shown, in particular for a motor vehicle, which features a wiper arm (18), which is able to support at least one wiper blade (22) and is fastened so that it can move in a rotating fashion at a minimum of one first coupling point (A) by means of a first crank (30) and at a second coupling point (B) that is different from the first coupling point (A) by means of a second crank (32). In addition, the cranks (30, 32) are linked at two fastening points that are different from the coupling points (A, B), whereby means (34) are provided to modify the distance between the two coupling points (A, B). In addition, a windscreen wiper device with a four-bar linkage is shown, whereby both cranks driving the wiper arm are causally driven.

A vehicle wiper system is provided including a cross-vehicle shaft that drives a pair of actuation mechanisms for driving a pair of wiper assemblies. The actuation mechanisms each include a crank, a connecting rod and a lever arm, whereby the connecting rod operably interconnects the crank and lever arm. The lever arm is fixed for rotation with a wiper post, which is in turn fixed to the wiper assembly. The actuation mechanism drives reciprocal rotation of the wiper post, thereby driving reciprocal sweeping motion of the wiper assemblies. The cross-vehicle shaft is driven by a motor that is controlled by a controller.

A wiper system for wiping a movable window (2), in particular of a motor vehicle, having a rotationally drivable first coupling part (10) for connection to a rotationally drivable drive shaft (9) disposed downstream of a stationary motor-gear unit (6), a second coupling part (15), which is connected to a wiper shaft (14) for driving a wiper (5), is movable in common with the window (2), and can be brought in centering fashion, relative to the drive shaft (9), with the first coupling part (10) in a torque-transmitting way along with the wiper shaft (14), and an overload-prevention means for limiting the torque that can be transmitted between the first coupling part (10) and the second coupling part (15), which prevention means is embodied in one piece with the first coupling part (10) and/or the second coupling part (15).
摘要:
This invention relates to windshield wiper system and method which utilizes a flexible member to account for compression loads in excess of a predetermined load, such as 30 percent, greater than a maximum load for the flexible member. The system utilizes a flexible pultruded composite material having a relatively low modulus of elasticity, yet relatively high elongation characteristics. The flexible arm bends to facilitate preventing damage to components in the wiper system when a compressive load applied to the flexible member is in excess of the predetermined load.
