Abstract:
1. A wiper blade ( 12 ) having a longitudinal axis and comprising an elongate, spring-elastic carrying element ( 36 ), which is pre-curved in a concave fashion with respect to a vehicle window ( 22 ) and has two spring rails ( 52 , 66 ) which run parallel to the longitudinal axis and parallel to one another in a plane, the spring rails having respective inner and outer longitudinal sides and respective end faces transverse to the longitudinal axis, the outer longitudinal sides having therein respective recesses, and the wiper blade also comprising a wiper strip ( 24 ) which is held with a web ( 34 ) of a head strip ( 30 ) between the spring rails ( 52 , 66 ) via the carrying element ( 36 ), said spring rails being inserted in longitudinal grooves ( 32 ) on both sides of the web ( 34 ), wherein the wiper strip ( 24 ) has ends and is secured in the longitudinal direction ( 20 ) relative to the carrying element ( 36 ) at least close to one of the ends of said wiper strip, characterized in that the spring rails ( 52 , 66 ) have, at the inner longitudinal sides facing one another in end regions, clips ( 60 , 74 ) with cutters ( 62 , 76 ), which, in a mounted state, cut into adjoining walls of the longitudinal grooves ( 32 ), and characterized in that a connecting piece ( 78 ) comprising lateral guide profiles ( 80 ) is guided on the spring rails ( 52 , 66 ) and presses said spring rails together, the lateral guide profiles being on opposite longitudinal sides of the connecting piece, the longitudinal sides of the connecting piece being generally parallel to the longitudinal axis, with each of the guide profiles having a U-shaped cross-section, as viewed in a plane perpendicular to the longitudinal axis, which is open toward an inside, and each of the guide profiles has spaced limbs ( 98 , 100 ) between which an associated spring rail extends in the mounted state, wherein the guide profiles are connected to one another by a top wall ( 82 ), which has in a central region a longitudinal channel ( 84 ) receiving the head strip of the wiper strip, wherein spring tongues ( 94 ) on the guide profiles ( 80 ) engage in the mounted state in the respective recesses ( 54 , 68 ) of said spring rails ( 52 , 66 ), wherein the spring tongues ( 94 ) extend in each case toward an oppositely disposed one of the limbs ( 98 , 100 ) of an associated guide profile, and wherein hooks ( 96 ) are integrally formed on outer ends of the guide profiles ( 80 ) and, during assembly, the connecting piece is pushed from the end faces onto the spring rails until the hooks bear against the end faces of the spring rails in the mounted state, and further comprising an end cap ( 44 ) that at least partially covers the connecting piece.
