  • Publication number: 20060121251
    Abstract: The object (10, 10?) comprises a first layer (1), for example with a back injection of a second layer (2), whereby the first layer is plastically deformable and comprises a front face (1a) and a rear face (1b). The back injection of the first layer (1) takes place in an injection mould. Before the back injection, the first layer (1) is partly provided with a coating (4?) on the front face (1a) thereof and said coating is hardened. The first layer (1) is then placed in an injection mould (6). The first layer (1) is then back injected in the injection mould (6), thus forming the second layer (2), such that the first layer (1) is pressed with the front face (1a) thereof on an inner side (7) of the injection mould (6) and the hardened coating (4?) on the first layer (1) is deformed and at least partly pressed into the first layer (1). The coating (4?) is preferably applied by printing, for example by means of a screen printing method.

  • Patent number: 6748706
    Abstract: The connection comprises a window frame (5, 5′), which extends along the lower edge (1a) of the windshield (1), which is fastened to the bottom side (1b) of the windshield, and which forms a channel (5) extending essentially parallel to the lower edge (1a). A wedge (14, 24, 34, 44, 54) is inserted into the channel (5) of the window frame (5, 5′) and fixes a retaining connecting member (2a) of the water deflector (2) inside the channel (5). The wedge (14, 24, 34, 44, 54) is preferably provided in the form of a strip. The connection enables the water deflector (2) to be mounted more easily and quickly.
