Wiper blade
First Claim
1. A wiper blade (10) with a wiper strip (12), into lateral longitudinal grooves (20) of which two spring rails (24) are inserted as a resiliently elastic supporting element, wherein ends of the spring rails (24) are connected to each other by a bridge (32, 54, 62, 76) by side parts (36, 66, 80) of the bridge (32, 54, 62, 76) being supported on upper sides of the spring rails (24) and engaging in cutouts in the spring rails (24) while a central part (34, 64, 78) of the bridge (32, 54, 62, 76) spans a back strip (22) of the wiper strip (12), the back strip upwardly bounding the longitudinal grooves (20), characterized in that end sides of the spring rails (24) have short slots (28) which run in a longitudinal direction of the spring rails (24) and into which 1-shaped angle pieces (38, 56) of the bridge (32, 54) engage, while lower limbs (40, 58) of the angle pieces (38, 56) are directed toward a center of the spring rails (24) and grip the spring rails from below, and characterized in that the central part (34, 64, 78) of the bridge (32, 54, 62, 76) has a tab (42) which, at a free end thereof, has at least one claw (44) which, in a fitted state, penetrates the back strip (22), the tab (42) facing ends of the spring rails (24) and extending between the side parts (36) of the bridge (32, 54).

Abstract
A wiper blade with a wiper strip, in the lateral longitudinal grooves of which spring rails are inserted as springy supporting elements. The ends of the spring rails are connected with one another by a bridge in that side parts of the bridge are supported at the upper side of the spring rail and engage recesses of the spring rails, whereas a middle part of the bridge bridges a back strip of the wiper strip, which forms the upper boundary of the longitudinal grooves. It is proposed that the spring rails, at their front faces, have short slots, which extend in the longitudinal direction of the spring rails and which are engaged by the I-shaped angle pieces of the bridge. Lower legs of the angle pieces are directed towards the middle of the spring rails, gripping these from below.
