The invention is based on a connection element () for connecting a wiper blade (), which has at least one spring rail () as a supporting element, to a wiper arm in an articulated manner, with the connection element () having claws () which are integrally formed on the side of a base part () and, in the mounted state, surround and retain the spring rail () by the base part () being supported on a part of a wiper rubber () which is arranged between the spring rail () and the base part (). The invention proposes that the connection element () has means () with which the surface pressure between the base part () and the wiper rubber () is locally increased.

Connection element

Disclosed is a windshield wiping device for a motor vehicle. A wiper arm is connected to a wiper bearing pin, the wiper arm being driven via the wiper bearing pin. The inventive windshield wiping device is characterized in that the wiper bearing pin is geometrically oriented in such a way that the lifting angle of the wiper arm changes in substantially one direction when the wiper arm performs a wiping movement across a windshield.

Windshield wiping device and method for the operation thereof

A wiper system using two wipers and two wiper motors, which drive the wipers and of which at least one first wiper motor forms a sub-assembly with an electronic control unit. The second wiper motor is a rotary motor having only one sensory system for detecting the absolute and relative rotational position of its driven shaft, which generates corresponding signals for the control unit of the first wiper motor, and the first wiper motor, in the rotational speed and the rotational position of its driven shaft, is regulated by the control unit as a function of the rotational position and the rotational speed of the driven shaft of the second wiper motor.

Wiper system using two wipers

A proposed wiper blade serves to clean the windshields of motor vehicles. The wiper blade () has an elongated rubber-elastic wiping strip which can be placed in contact against the windshield to be wiped and which is held substantially parallel to the longitudinal axis at an elongated, springing-elastic carrying element (). A connection device () for complementing connection means of a driven wiper arm () which are loaded toward the windshield is arranged at the center portion of the carrying element (). The connection device has two stop surfaces () which are located at a distance from one another, extend transverse to the driving direction, are parallel to one another and oriented in planes extending vertical to the windshield, and cooperate with counter-stops of the wiper arm. A problem-free and economical arrangement of the connection device at the carrying element is carried out in that one of the two structural component parts (or) which are connected with one another is provided with elastically deflectable catch means which cooperate with the complementing catch means of the other structural component part (or) in such a way that the two structural component parts are locked together.

Wiper blade for motor vehicle windows

A wiper blade for wiping windows of motor vehicles has an elongated rubber-elastic wiper strip placeable on a window to be wiped and arranged substantially longitudinally axially parallel on a surface of a strip-shaped, spring-elastic support element which is connected with a wiper arm which is spring loaded toward the window and driven transversely to a longitudinal extension of the wiper blade, and a leading-edge face extending longitudinally of the wiper blade and substantially parallel to the window and facing into a wind so as to form an acute angle with the window.

In the case of a housing part according to the related art, it is still necessary to assembly many components using additional assembly steps. They includes a connector and a brush holder, for example. A housing part () designed according to the invention includes a brush holder () and mounting feet () that are designed integral with the housing part (), so that further assembly steps are eliminated.

Housing part for an electrical adjusting drive

A windshield wiper includes a drive shaft ( ), to which shaft a crank ( ) is fastened. A base body ( ) of the drive shaft ( ) is made from an extruded light metal profile and on its free end, in the region of a fastening part, carries a connection part ( ) of a harder material, which has a screw thread ( ).

Primary shaft for a windscreen wiper

The invention is a wiper arm ( ) for securement to a drive shaft ( ). The wiper arm ( ) has a securing part ( ), which on one end has a bearing point ( ) by way of which the wiper arm can be connected, in a manner fixed against relative rotation, to the drive shaft ( ) via a nut ( ). The nut can be screwed onto the drive shaft ( ). The nut is formed by a component integrally cast onto the securing part ( ) and is connected to the securing part ( ) via a binding ( ) that can be released upon installation of the wiper arm ( ).

Wiper arm with integral nut

A wiper blade ( ) is proposed that serves to clean windows of motor vehicles. The wiper blade has an elongated, rubber-elastic wiper strip ( ) which is provided on its two long sides with respective facing longitudinal grooves ( ), in each of which one spring rail ( ), protruding intermittently from the grooves by one longitudinal edge ( ), is disposed; the spring rails belong to an elongated, spring-elastic support element ( ) for the wiper strip ( ), on whose middle portion a connection device ( ) for a wiper arm ( ) guided on the vehicle body is disposed. An especially simple disposition of a wind deflector strip and a connection device for a wiper arm are obtained if at least one longitudinal portion of the part of the wiper strip located on the side of the spring rails ( ) remote from the window is embodied as a wind deflector strip ( ), and if furthermore the connection device ( ) is retained on the longitudinal edges ( ) of the spring rails ( ) that protrude from the longitudinal grooves ( ).

Wiper blade for cleaning windows of motor vehicles

A wiper arm of a windshield wiper has a driven fastening part which is pivotably connected to a joint part, the joint part is rigidly joined by a wiper rod ( ), at least one of the parts of the wiper arm is shaped from sheet metal, at least one of the parts formed from sheet metal has at least one region with a plurality of material layers folded up onto one another.

Wiper arm

A spray nozzle ( ) for a window or glass washing system has a nozzle element ( ) in which at least part of a flow conduit ( ) is firmed by an elastic hoselike part ( ), which closes the flow conduit ( ) and under the influence of a washing fluid pressure, widens elastically:and uncovers the conduit ( ). The hoselike part ( ), with its flow conduit ( ), rests tightly in the pressureless state, with an initial tension, on a mandrel ( ).

Spray nozzle for a windscreen washer system

A wiper blade is proposed, which is used to clean motor vehicle windows. The wiper blade has an elastic, elongated load bearing element for an elongated wiper strip, made of a flexible material, that can be pressed against the window to be washed, which strip, on its long sides, has longitudinal grooves facing one another, in which spaced-apart longitudinal rails of the load bearing element are located, whose middle portion has a connection device for a driven wiper arm, and the cross section of the two longitudinal rails decreases from its middle region out toward the ends of the rails. A wiper blade that is especially easy to mount is obtained if the load bearing element takes the form of a hairpin, the two legs of which form the longitudinal rails, and the free ends of the two longitudinal rails are held together, in particular being joined together, by stabilizing means embodied as a separate component.

The support element is embodied as elongated in bandlike fashion, and it comprises an elastic plastic. The rubber-elastic wiper strip, elongated in bandlike fashion, can be secured to the support element longitudinally axially parallel. An especially durably operationally reliable support element is obtained if the support element is made from a fiber-reinforced thermoplastic plastic, and the fibers are admixed with the plastic.
