WINDSHIELD WIPER BLADE HAVING AN INTEGRATED SPRAYING DEVICE

摘要

The invention relates to a wiper blade (1) for a motor vehicle windshield (6) comprising a supporting mount (2) having a main longitudinal orientation, having lower means having a wiper part (4), said supporting mount (2) being intended to be moved along a predetermined path between two end positions over a wiping cycle of the windshield (6), and a device (7, 8) for spraying cleaning liquid comprising at least a first set of spray orifices oriented in said main longitudinal orientation over at least a part of a first side of the blade so as to spray washing liquid in front of the blade with respect to the wiping movement. According to the invention, the spray orifices are distributed over said first side at a non-constant spacing, the distance between two successive orifices being selected such that the portion of the windshield surface that is effectively sprayed by a spray orifice during a wiping cycle is approximately equal to the same target value for all of the spray orifices of the first set.
