Wiper blade for glass surfaces of motor vehicles
DCFirst Claim
1. A wiper blade for motor vehicles windows, comprising an elongated rubber-elastic wiper strip having a wiper lip and two longitudinal sides with two longitudinal grooves located substantially in one plane so that between both longitudinal grooves a bridge is provided;
- a band-shaped elongated spring-elastic carrier element is defined by a pair of springs, the springs are accommodated in the longitudinal grooves so as to each extend with at least a section outwardly beyond a respective longitudinal groove, wherein with respect to a longitudinal center line of the wiper strip the sections are located opposite to one another to define facing and opposite longitudinal edges and at least on one of the sections a bridge-shaped component that overlaps both springs fits against opposite longitudinal edges of the springs, so that a distance between the facing longitudinal edges of the springs is greater than a width of the bridge to define a clearance, and means for maintaining the clearance is arranged on the component.

Abstract
The invention relates to a wiper blade (10) for motor vehicle windows. The wiper blade includes a rubber-elastic wiper strip (20) stretched out long in the manner of a band that can be placed against the window with a wiper lip, the two side walls of which each include a longitudinal groove (28, 30) which is situated in a plane that is basically parallel to the window (14) and has clearance from the window, so that a bridge (34) remains between the two grooves, and a spring (36 and/or 38) is accommodated in each longitudinal groove-that belongs to a spring-elastic carrier element (12) stretched out long in the manner of a band. Retention of the required flexibility of the wiper blade even with problematic window configurations is ensured when the distance (44) between the facing longitudinal edges (40, 42) of the two springs (36, 38) is greater than the width (46) of the bridge (34).
