Abstract:
A method for producing a support element (12) in combination with a wiper strip of a wiper blade (10) of a motor vehicle, the support element being spring-elastic and connectable to a free end of (20) of a driven wiper arm (18) and formed as an elongated band-shaped element which is made from a fiber reinforced thermoplastic plastic material, in which fibers are admixed with a plastic material, and the wiper strip (14) being an elongated band-shaped elastic strip extending longitudinally parallel to the support element (12) and secured directly to a bottom side of the support element, and the support element comprising a connection device (16) for connecting the support element to the free end of the wiper arm, the connecting device being provided on an upper side of the support element, wherein when the wiper blade presses against a window surface to be washed, a tension is built in the spring-elastic support element thereby ensuring a proper contact of the wiper strip (14) with the window surface to be washed wherein the connection device (16) includes two stubs (30, 32) positioned in a center portion of the support element (12) and spaced apart from one another parallel to a length of the support element and are connected to one another via a connection peg (22) extended crosswise to the length of the support element, the method in which the fiber-reinforced plastic material is introduced via a filling opening in to a middle portion of a closed mold (50) in an axial direction of the connection peg (22) of the support element to be produced, so that the fiber-reinforced plastic material is forced from the middle portion out via the stubs (30, 32) to the ends of the support element, and the finished support element can be removed after an opening of the mold, wherein the connection device (16) for connecting the support element to the free end of the wiper arm (18) is integrally formed with the support element (12), wherein the connection device (16) includes two stubs (30, 32) positioned in a center portion of the support element (12).
