DEFINITION

Classification: 15/250.451

Specific backing member:

(under subclass 250.44) Apparatus wherein the cleaning element support structure includes a stiffening element extending along the back of the surface-contacting-foreign-matter-removing member (e.g., squeegee, windshield wiper blade, etc.).

(1)

Note For this and indented subclasses, specific backing member requires more than the recitation of a "backing member," "backing member having a slot to retain a squeegee," or "means for retention by articulated structure."

(2) Note. The backing member is usually flat so as to permit flexing about an axis, perpendicular to its longitudinal axis and parallel to the optical element, so as to accommodate a curved optical element.
