The invention is based on a link element () for windshield wipers, which is adjoined by a wiper rod () and is manufactured out of a metal sheet () by means of stamping and bending, in which, starting from a longitudinally aligned covering wall (), at least one wall part of a side wall () is comprised of a number of sheet metal layers produced by being bent inward by 180&#xb0;, and a hanging device () for a tension spring is fastened to the innermost sheet metal layer and protrudes into a free space () between the side walls (). The invention proposes that a slot () lateral to the longitudinal direction () of the link element () be let into the innermost sheet metal layer from the bottom edge () and that a pin () be inserted into this slot.

Joint part for a windshield wiper

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 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

Fastening element for a wiper arm, and method of manufacturing the same

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 arm has a fastening element and a cap which surrounds the fastening element and is supported via a bearing face in the form of a closed C radially continuous about a toggle joint covering an angle of more than 180&deg; to maintain the cap on the fastening element so that it can be hinged open to the joint.
