Claim Text:
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 ).
