Abstract: The invention is based on a link element (10) for windshield wipers, which is adjoined by a wiper rod (28) and is manufactured out of a metal sheet (16) by means of stamping and bending, in which, starting from a longitudinally aligned covering wall (40), at least one wall part of a side wall (38, 42) is comprised of a number of sheet metal layers produced by being bent inward by 180°, and a hanging device (32, 52, 54; 60; 58, 64) for a tension spring is fastened to the innermost sheet metal layer and protrudes into a free space (30) between the side walls (38, 40). The invention proposes that a slot (52) lateral to the longitudinal direction (56) of the link element (10) be let into the innermost sheet metal layer from the bottom edge (50) and that a pin (54) be inserted into this slot.

Abstract: A windshield wiper includes a drive shaft (10), to which shaft a crank (12) is fastened. A base body (14) of the drive shaft (10) is made from an extruded light metal profile and on its free end, in the region of a fastening part, carries a connection part (16, 22) of a harder material, which has a screw thread (18).

Abstract: The invention is a wiper arm (20) for securement to a drive shaft (10,12). The wiper arm (20) has a securing part (18), which on one end has a bearing point (16) by way of which the wiper arm can be connected, in a manner fixed against relative rotation, to the drive shaft (10, 12) via a nut (14). The nut can be screwed onto the drive shaft (10,12). The nut is formed by a component integrally cast onto the securing part (18) and is connected to the securing part (18) via a binding (26) that can be released upon installation of the wiper arm (20).

Abstract: 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 (18, 62), 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.

Abstract: The invention is based on a fastening element for a wiper arm, which on one end has a first fastening region (12) with a conical hub (14) and on another end has a second fastening region (18) with a bearing point (20). It is proposed that the fastening element comprises a middle, longitudinally extending, prefabricated carrier part (22), and the fastening regions (12, 18) are formed by separate heads (24, 26) cast onto two ends (10, 16) of the carrier part (22).

Abstract: A spray nozzle (10) for a window or glass washing system has a nozzle element (24) in which at least part of a flow conduit (36) is firmed by an elastic hoselike part (26, 28, 30), which closes the flow conduit (36) and under the influence of a washing fluid pressure, widens elastically:and uncovers the conduit (36). The hoselike part (26, 28, 30), with its flow conduit (36), rests tightly in the pressureless state, with an initial tension, on a mandrel (18, 20, 22, 54, 56).

Abstract: 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° to maintain the cap on the fastening element so that it can be hinged open to the joint.
