Wiper blade for cleaning glass panes, in particular of vehicles

A wiper blade is proposed for cleaning spherically curved panes (22), in particular of motor vehicles. The wiper blade (10) has an elongated, rubber-elastic wiper strip (14) that can be applied with a wiper lip (24) to the pane (22), which is held on a band-like elongated, spring-elastic support element (12), which has two spring rails (40) arranged at a distance from one another and parallel to one another, which each grip at least with longitudinal strips (50) into open-ended longitudinal grooves (42) of the wiper strip (14), whereby on the groove walls (52, 54, 56) of the wiper strip (14) surfaces (161, 162, 163) rest against the spring rails. A particularly quiet, trouble-free wiping operation is ensured if lubricants (60 or 160) are arranged between the groove walls (52, 54, 56) of the wiper strip (14) and surfaces of the spring rails (40 or 140).
