  • Patent number: 8191201
    Abstract: The invention is based on a connection element (16, 44, 50, 66, 74, 80) for connecting a wiper blade (10), which has at least one spring rail (14) as a supporting element, to a wiper arm in an articulated manner, with the connection element (16, 44, 50, 66, 74, 80) having claws (22, 46, 52) which are integrally formed on the side of a base part (18) and, in the mounted state, surround and retain the spring rail (14) by the base part (18) being supported on a part of a wiper rubber (12) which is arranged between the spring rail (14) and the base part (18, 56, 68, 70). The invention proposes that the connection element (16, 44, 50, 66, 74, 80) has means (28, 58, 60, 68, 72, 76, 78, 82, 84) with which the surface pressure between the base part (18, 56, 68, 70) and the wiper rubber (12) is locally increased.

  • Patent number: 7971312
    Abstract: The invention relates to a connecting element (22) for hingedly connecting a wiper blade (10) to a wiper arm, said wiper blade (10) having a wiper strip (12) and at least one sprung blade (20) inserted into the wiper strip (12). Said sprung blade projects beyond the wiper strip (12) in the area of the connecting element (22) and is enclosed by guide rails (30) that are interlinked by at least one spring clip (34) and secured in the longitudinal direction of the wiper blade (10) by at least one locking element (38) which laterally engages with a recess (28) of the sprung blade (20).

  • Patent number: 7644483
    Abstract: The invention relates to a method to manufacture a wiper blade (10) as well as a device to perform the method and a wiper blade (10) that is manufactured accordingly, wherein the wiper blade (10) features at least a basic body (56) featuring a wiper strip (24) and a supporting element (12). According to the method, the basic body (56) is supposed to be positioned in a holding device (58) in such a way that a clearance (63) remains between the supporting element (12) and holding device (58) at least in areas. The wind deflector strip (44) is gripped, at least one claw (46, 48) formed on the wind deflector strip (44) is threaded on the supporting element (12) and the wind deflector strip (44) is placed over the supporting element (12).

The guide rails (30) and the spring clip (34) are produced from a plastic material. The invention is characterized in that the connecting element is composed of a plastic securing part (26) and a metal bearing part (24), the securing part (26) being adapted to laterally enclose the sprung blade (20) with its guide rails (30) and having front walls (40) at its ends that project outward beyond the contours of the guide rails (30).
