Vehicle windscreen wiper blade with glue gallery

摘要

The wiper arm (10) carries a wiper blade (14) and a washing liquid supply pipe (18) which are fixed on the arm by sticking with a glue film (20) . The supply pipe has a housing (26), in the form of a longitudinal groove, which discharges onto the sticking surface (24) and which is filled with glue (20). The width (L1) of the housing is greater than the width (L2) of its face opening onto the sticking surface. The wiper arm sticking surface is plane (12) and the blade sticking surface has a V section open at the centre from which discharge the open face of the housing (26). The glue film extends inside the housing and along the internal faces (28) of the open V branches.
