摘要:
A windscreen wiper arm (1), comprising a mounting head (2) mountable on a drive shaft (3) and a first arm member (4) at one end thereof being pivotally connected to the mounting head (2) by means of a pivot pin (8) and at another end thereof being rigidly connected to a second arm member (5) arranged to be connected to an elongated wiper blade (6) to be placed in abutment with the windscreen to be wiped. The first (4) and said second (5) arm members can oscillate to-and-from between a first reversal position and a second reversal position. The second arm member (5) is made in one piece and has a substantially U-shaped cross-section defining a housing between a base and legs of said U-shaped cross-section. The housing is arranged to accommodate at least one channel (14, 15) for a washing liquid and/or electricity wiring.

The present invention relates to a device for dispensing a windshield-cleaning liquid for windshield wiper blades of a motor vehicle, comprising: a hydraulic pipe (7, 8) having at least one liquid flow channel (7a, 7b, 8a, 8b); at least one hydraulic coupling (9, 10, 11, 15) for transporting of liquid to said pipe or discharging the liquid from said pipe, characterized in that the dispensing device also comprises at least one non-return valve (20) received in the flow channel (7a, 7b, 8a, 8b) or in a hydraulic coupling (9, 10, 11, 15).
摘要:
A wiper device for cleaning a vehicle window is disclosed. The wiper device has a wiper arm fastened in a torque-proof manner to a wiper shaft via an articulation piece, where the wiper arm is arranged pivotably on the articulation piece, a wiper blade arranged on the wiper arm, and a washing device for the wiper blade, which contains a feed for a washing fluid, where the feed runs in a partial region in the longitudinal axis of the wiper shaft and leads to the wiper blade in a direction running substantially perpendicularly to the longitudinal axis.

The present invention relates to a windscreen wiper (1) for a motor vehicle window (3), comprising: a longitudinally extending wiper blade (5), an aerodynamic deflector (9) extending longitudinally above said wiper blade (5), at least one longitudinally extending fluid circulation duct (31, 32) having at least one spraying orifice (35), characterized in that the wiper comprises at least one lower lateral skirt (43, 44) extending longitudinally on a lateral side of the wiper blade (5) and of the spraying orifice (35), the spraying orifice (35) being located between the wiper blade (5) and the lower lateral skirt (43, 44).
摘要:
A wiper assembly for sweeping a glass surface on a vehicle. The wiper assembly includes a windshield washer assembly connected to the windshield wiper drive arm of the vehicle for controllably dispensing washer fluid directly down onto the glass surface of the vehicle. The wiper assembly also includes a novel control unit carried by the vehicle for controlling the dispensing of the washing liquid from the windshield washer assembly. Uniquely, the control unit includes a sensor that is operably associated with the pump for sensing the position of the wiper arm as it moves upwardly and downwardly relative to the glass surface and for controllably energizing the pump at selected positions of the wiper drive arm so that the washer fluid is always dispensed forwardly of the wiper blade to avoid smearing.
摘要:
A wiper drive system and method for installation of a wiper pivot shaft through a structure whose opposite faces may not be parallel. A mounting body supports a bearing support tube and has a concave front side. A mounting ring surrounds the bearing support tube and has a convex rear side that rests adjustably against the concave front side of the mounting body.

This invention relates to windshield wiper system which utilizes a flexible drive arm for withstanding bending loads applied to a wiper. The drive arm may be made of a pull-molded composite material having a relatively low modulus of elasticity and a relatively high elongation factor. The flexible arm twists in the presence a bending load and undergoes rapidly progressing elastic buckling when the bending load exceeds a predetermined amount.
摘要:
A windshield cleaning system with a wiper shaft for driving a wiper arm-and-blade assembly is described, which windshield cleaning system comprises an axial bore for forming a washing liquid channel, whereby at least one electric conductor for heating the washing liquid is assigned to the washing liquid channel. Thereby the electric conductor is anchored on a pipe, which is arranged in the bore of the wiper shaft, whereby this pipe extends the end of the wiper shaft by way of at least one end portion and can detachably be connected there with a counter contact piece. Due to the plug connection of the electric conductor an easy assembly is possible.
摘要:
A wiper for sweeping off a glass surface of a vehicle, in which an arm head is pivotally mounted on a wiper shaft, and includes a wiper section for sweeping off the glass surface when the arm head is pivoted around the wiper shaft, in which a device for adjusting the thrust pressure of the wiper section against the glass surface and/or a driving device for the wiper section may be arranged in the arm head, and electric power is supplied to the devices through a cord, and in which the arm head also includes a pivot mount portion where the arm head is pivotally mounted on the wiper shaft and a come-out portion formed near the pivot mount portion, for leading out the cord in a tangential line direction of a locus of the pivoting pivot mount portion.
