ABSTRACT:
A wiper arm (30) for a vehicle windshield wiper assembly (14) has at least a section along its longitudinal extent formed of a longitudinally extending base portion (80) and two spaced side walls (82,84) extending outwardly along opposite sides of the base portion (80) to form an open channel (85). A spray nozzle (70i is disposed in the outboard portion of the wiper arm (30) and a fluid delivery tube (60) extends longitudinally along the wiper arm (30) to deliver wash fluid from a supply to the spray nozzle (70). The outboard edges (86,88) of the outwardly sidewalls (82,84) are folded inwardly towards each other to partially close the open face (87) of the channel (85), thereby retaining the fluid delivery tube (60), which is freely disposed, within the channel.
