Windshield wiper assembly with scrubbing blade

A windshield scrubbing and wiping blade assembly adapted to be connected to a windshield wiper arm, the blade assembly comprising:

• a blade support adapted for connection to the windshield wiper arm;
• an elongate scrubbing blade attached to the blade support and having a scrubbing portion, the scrubbing portion including a base and a tip projecting from the base, the base having side walls converging toward the tip, the scrubbing blade including a scrubbing mesh enveloping the base and tip, said mesh having edge margins;
• and
• at least one wiper blade attached to the blade support, the at least one wiping blade being disposed parallel to and spaced apart from the scrubbing blade, whereby during operation of the windshield wiper arm the scrubbing blade mesh scrubs said windshield to remove debris therefrom and the at least one wiping blade clears the windshield of the debris during at least a portion of the wiper arm cycle, wherein:
• the scrubbing blade further includes an attachment portion for connecting the scrubbing blade to the blade support, the attachment portion being connected to the base by a central web, the scrubbing blade further including a pair of flange portions projecting laterally from said web, the base having bilaterally extending shoulders confronting said flange portions, each said shoulder and flange portion defining a slot between them for receiving an edge margin of the mesh.

A windshield scrubbing and wiping blade assembly, for removing debris from a windshield, said assembly being adapted to be connected to a windshield wiper arm, the blade assembly comprising:

• a blade support adapted for connection to the windshield wiper arm;
• an elongate scrubbing blade attached to and extending from the blade support and having a scrubbing portion, the scrubbing portion including a base and a tip projecting from the base, the base having side walls converging toward the tip, the scrubbing blade including a mesh capable of passing debris therethrough, said mesh enveloping the base and tip, the tip having an extremity, said mesh having edge margins;
• and
• a wiping blade attached to and extending from the blade support, the wiping blade being disposed parallel to and spaced apart from the scrubbing blade and including a tip having an extremity, the distance from the blade support to the extremity of the scrubbing blade tip being less than the distance from the blade support to the extremity of the wiping blade tip whereby during operation of the wiper arm in one direction, the scrubbing blade is in contact with the windshield and the wiping blade clears the windshield behind the scrubbing blade, and during operation of the wiper arm in the other direction, the scrubbing blade is out of contact with the windshield, and in which:
• the scrubbing blade further includes an attachment portion for connecting the scrubbing blade to the blade support, the attachment portion being connected to the base by a central web, the scrubbing blade further including a pair of flange portions projecting laterally from said web, the base having bilaterally extending shoulders confronting said flange portions, each said shoulder and flange portion defining a slot between them for receiving an edge margin of the mesh.
