Abstract A connector for connecting one type of windshield wiper arm end to a cross pin-type wiper blade. The arm end is releasably attached to the connector which connector has a body portion with a pin-receiving slot on the forward end thereof. The orientation of the pin-receiving slot with respect to the longitudinal axis of the body portion is such that to assemble the arm to the pin on the blade, the axis of the arm and connector relative to the longitudinal axis of the blade approaches 75° to 90°. The pin-receiving slot is forced over the pin on the blade to seat the pin in the slot. Once the pin on the blade is in the slot in the connector, the arm is pivoted relative to the blade until the axis of the arm is substantially parallel to the axis of the blade. The width of the connector is such as to contact the walls of the opening in the blade to guide the arm relative to the blade and at the same time the body portion of the connector fits into said opening in the blade and has a shoulder to prevent the connector from becoming disengaged from the blade during normal use of the blade.
A connector for connecting a wiper arm to a wiper blade, said wiper arm having an outer end portion releasably attached to said connector, said wiper blade having a bridge member with an opening formed through the back thereof, a cross pin anchored on said bridge in alignment with said opening, said connector having a body portion, a forward part of said body portion having a gradually tapering slot extending inwardly therefrom and terminating in an enlarged circular aperture of a diameter larger than the width of a throat in said tapering slot, oppositely directed flanges extending outwardly from the peripheries of the opposite sides of said body portion, said flanges engage with walls of said opening in said blade to guide said connector during relative movement between the connector and said blade a single web connected to the mid-portion of said body portion and extending rearwardly therefrom, said web having a rear edge spaced from the center of said aperture an amount slightly less than the distance from the center of said pin to the adjacent edge of said opening in the bridge, said single web having a downwardly facing bottom edge coplanar with the bottom wall of the body portion and extending rearwardly an amount substantially equal to the distance from the center of the pin to said rear edge, said bottom edge having a lateral dimension equal to the thickness of said web, whereby said web prevents said connector from being removed from said blade when said blade and wiper arm are in normal operating position.
