Wiper system having a pin-style wiper arm and wiper assembly

A wiper arm and wiper assembly for use in connection with a wiper system, said wiper arm and wiper assembly comprising:

• a wiper arm having a pivot end operatively engaged to a drive assembly of a wiper system, an attachment member and an elongate body disposed between said attachment member and said pivot end, said attachment member including a deck extending axially from said elongate body, a tab and a wall plate, said tab and said wall plate depending from said deck substantially parallel to each other and cooperate with said deck to define a channel, said attachment member further including a transversely extending pin relative to said tab;
• a wiper assembly including a wiping element adapted to contact a surface to be wiped, an elongated beam operatively attached to said wiping element and a carrier adapted to facilitate releasable connection to said wiper arm, said carrier having opposed first and second sidewalls that cooperate to define a track to operatively receive a portion of said elongate beam and a coupler integrated within said first sidewall to releasably engage said attachment member, said coupler having a bore adapted to operatively receive said transversely extending pin and saddle adapted to be operatively disposed within said channel, said saddle including first and second guide surfaces adapted to limit the rotational movement of said wiper assembly relative to said wiper arm during releasable connection thereto;
• and
• wherein said deck cooperates with said wall plate to define a leading edge and further cooperates with said tab to define a trailing edge, said deck extending from said leading edge toward said trailing edge along an inclined plane relative to the horizontal axis of said transversely extending pin to maximize downward force of air current applied to said deck to reduce the likelihood of wind lift of said wiper assembly during operational movement across a surface to be wiped.
