| 摘要 |
The invention relates to a wiper blade (10) in a flat bar construction, having a rubber-elastic wiper strip (14), in the lateral longitudinal grooves (24) of which two band-shaped spring rails (28) which extend next to each other in a parallel manner and which are bent concavely toward a wiper lip (16) are inserted as support elements which protrude laterally out of the longitudinal grooves (24), and which are held together and attached to each other at the ends thereof by end caps (36) which, on the longitudinal sides thereof, have guide profiles (44) having a u-shaped cross section, the side jaws (46, 48, 60) of which are guided on the portions of the associated spring rail (28), which protrude out of the longitudinal grooves (24), wherein the end caps (36) comprise spring tongues having engagement lugs (50, 62) which engage in recesses (30) of the spring rails (28) and attach same in the assembly direction (52). According to the invention, one of the side jaws (46, 48, 60) of each guide profile (44) is designed to be at least partially elastic and is used as spring tongue, and the engagement lug (50, 62) is molded on the yielding portion of the side jaw (46, 48, 60), wherein the height of said engagement lug decreases in the assembly direction (52) and thus forms a striking bevel (54), while the engagement lug (50, 62) drops off steeply in the opposite direction. |

1. A wiper blade (10) in a flat bar construction, having a rubber-elastic wiper strip (14), in longitudinal grooves (24) of which two band-shaped spring rails (28) which extend next to each other in a parallel manner and are bent concavely toward a wiper lip (16) are inserted as support elements which protrude laterally out of the longitudinal grooves (24), and which are held together and attached to each other at ends thereof by end caps (36) which, on longitudinal sides thereof, have guide profiles (44) having a u-shaped cross section, side jaws (46, 48, 60) of which are guided on portions of the associated spring rail (28), which protrude out of the longitudinal grooves (24), wherein one of the side jaws (46, 48, 60) of each guide profile (44) is at least partially elastic and comprises an engagement lug (50, 62) which engages in a recess (30) of the associated spring rail (28) and fixes the spring rail in an assembly direction (52), wherein the engagement lugs (50) are provided on side jaws (46) of the guide profile (44) which are more remote from the wiper lip (16), while other side jaws (60) of the guide profile (44) cover said engagement lugs (50) toward an end wall (56) of the end cap (36) and terminate before said end wall, and wherein the side jaws (48) of the guide profile (44) nearest to the wiper lip (16) terminate at ends thereof facing the end wall (56) of the end cap (36) before a highest protrusion of the engagement lugs (50); thus enabling the engagement lugs (50) to at least partially traverse said side jaws (48). |
