<p>The windscreen surface (50) is swept by the squeegee (56) portion of the blade (52), whose upper portion (54) is gripped by the blade holder. The pin (46) of the blade holder (40) is gripped by the attachment (26,34). The attachment has a leading edge (20) and a vertical fence (14). The leading edge (20) of the attachment is contoured to divert the airflow (12), part of which passes through the slot (140) in the fence, the overall effect being a downward force pressing the wiper blade toward the windscreen.</p> |
