The invention relates to a wiper blade (10) designed as a flat bar with a wiper strip (12) which is held by a spring-elastic elastic strip support element (14) that is pre-curved in a concave manner with respect to a wiper lip (16) of the wiper strip (12). One or more spoiler parts (22, 23) are attached to the support element (14) face facing away from the wiper lip (16) by means of guiding profiles (30) which cover the support element (14) from the outer longitudinal faces and project to a certain extent with respect to the outflow side (26) of the spoiler part (22, 23) and which form a groove (31) with said outflow side. A connecting element (18, 64) is fixed in the central region of the wiper blade (10) for connecting a wiper arm in an articulated manner. According to the invention, the guiding profile (30) on the outflow side (26) has a guiding ridge (32, 34, 40) on the guiding profile longitudinal face pointing outwards.
A wiper blade (10) of flat bar construction, having a wiper strip (12) which is held by a band-like, resiliently elastic carrier element (14) which is pre-curved in a concave manner with respect to a wiper lip (16) of the wiper strip (12), wherein one or more spoiler parts (22, 23) are mounted by means of guide profiles (30) on a side of the carrier element (14) which faces away from the wiper lip (16), which spoiler parts enclose the carrier element (14) from the outer longitudinal sides and protrude to a small extent beyond a flow-off side (26) of the spoiler part (22, 23) and form, with said flow-off side, a fillet (31), and wherein an attachment element (18, 64) for the articulated connection of a wiper arm is fastened in the a central region of the wiper blade (10), characterized in that the guide profile (30) on the flow-off side (26) has, on an outwardly pointing longitudinal side of the guide profile, a guiding rib (32, 34, 40).
