A parting line is set at the longitudinal center of the backing housing hole.

The invention relates to a windshield wiper device for a vehicle, for wiping a window (4), comprising a wiper blade (2) that has an elongate upper part (10) and an elongate lower part (12) which are at least partly flexible. Also provided is a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), the connecting elements (18) being spaced apart along a longitudinal direction (8) of the wiper blade (2) and being attached to the upper part (10) and/or the lower part (12) by a rotary joint (20), and the connecting elements (18) being designed to allow a motion of the upper part (10) and the lower part relative to each other with a motion component along the longitudinal direction (8) of the wiper blade (2). Each connecting element (18) extends along a longitudinal axis (24) of the connecting element (18) and along a transverse axis (25) running perpendicular to the longitudinal axis (24), which runs from the upper part (10) to the lower part (12). The transverse axes (25) of at least two connecting elements (18) adjoining each other along the longitudinal direction (8) define a demolding angle (β) of at least 0.5° relative to one another.

A process for the production of a coated rubber item, comprising: (i) provision of a semifinished product having the main shape of the rubber item, where the semifinished product is composed of a rubber composition comprising at least one rubber and at least one crosslinking agent; (ii) coating of the semifinished product with a solvent-free coating composition comprising at least one monomer amenable to free-radical polymerization, (iii) crosslinking of the rubber composition and polymerization of the coating composition, to give a coated rubber item;
wherein the boiling point of the at least one monomer amenable to free-radical polymerization is ≥150° C. and the crosslinking of the rubber composition takes place at the same time as the polymerization of the coating composition.

A wiper unit for an automobile windshield wiper system has at least one wiper arm connectable to a wiper drive of the windshield wiper system and at least one wiper blade supported by the wiper arm. In order to provide a lightweight wiper unit that can be produced cost-effectively and offers greater design freedom, at least one fiber-reinforced nonmetallic strip is arranged on the outside of the wiper arm and/or the wiper blade. That nonmetallic strip extends over at least half the length of the wiper arm or wiper blade, is connected to the wiper arm or the wiper blade in a substance-bonded manner, and is arranged at least in part on a side of the wiper arm or wiper blade which is arranged facing or facing away from an automobile windshield which is to be wiped.

The invention relates to a method for reducing material creep processes of a windshield washer device. The method comprises the providing (201) of a windshield washer device for a vehicle. The windshield washer device comprises a wiper blade (2) having an elongated top part (10) and an elongated bottom part (12), which are designed to be at least partially bendable. Furthermore, there is a plurality of connecting elements (18) for connecting the top part and the bottom part, wherein the connecting elements are spaced apart from each other along a longitudinal extension (8) of the wiper blade. The connecting elements (18) are designed to enable a movement of the top part (10) and the bottom part (12) relative to each other, having a movement component along a longitudinal extension (8) of the wiper blade. The method further comprises a loading (202) of the windshield wiper device before final assembly of the windshield wiper device on a vehicle such that, after final assembly of the windshield wiper device, a primary creep behavior of the windshield wiper device is substantially reduced, in particular by at least 80%.

The backing imparts rigidity and elasticity to the blade rubber. The rubber holder holds both the longitudinally intermediate section of the blade rubber and the longitudinally intermediate section of the backing. The rubber holder has a backing housing hole for housing and retaining the backing. The backing housing hole longitudinally extends through the rubber holder. A parting line is set at the longitudinal center of the backing housing hole.

A wiper blade rubber strip and a method for manufacturing the same are disclosed. The wiper blade rubber strip includes a rubber strip body made of a first rubber material and a blade portion made of a second rubber material. The blade portion is integrally formed with the rubber strip body by co-extrusion. The rubber strip body and the blade portion are made of different materials to meet their respective performance requirements of the rubber strip body and the blade portion.

The invention relates to a windshield wiper device for a vehicle, for wiping a window (4), comprising a wiper blade (2) that has an elongate upper part (10) and an elongate lower part (12) which are at least partly flexible. Also provided is a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), the connecting elements (18) being spaced apart along a longitudinal direction (8) of the wiper blade (2) and being attached to the upper part (10) and/or the lower part (12) by a rotary joint (20), and the connecting elements (18) being designed to allow a motion of the upper part (10) and the lower part relative to each other with a motion component along the longitudinal direction (8) of the wiper blade (2). Each connecting element (18) extends along a longitudinal axis (24) of the connecting element (18) and along a transverse axis (25) running perpendicular to the longitudinal axis (24), which runs from the upper part (10) to the lower part (12). The transverse axes (25) of at least two connecting elements (18) adjoining each other along the longitudinal direction (8) define a demolding angle () of at least 0.5 relative to one another.
