Windshield wiper blade device

Abstract

Title: Windshield wiper device. The invention relates to a windshield wiper device (10) for cleaning a vehicle windshield (12), comprising at least one wiper blade (16a, 16b) extending in a longitudinal direction (L) and having a plurality of nozzle elements (100) for applying a fluid (24), in particular a cleaning fluid, to the windshield (12), wherein the nozzle elements (100) are arranged on the wiper blade (16a, 16b) distributed in the longitudinal direction. It is proposed that the wiper blade (16a, 16b) have at least one first longitudinal section (70a) and at least one second longitudinal section (70b), wherein the nozzle density in the first longitudinal section (70a) is lower relative to the longitudinal direction (L) than in the second longitudinal section (70b) of the same wiper blade (16a, 16b).
