摘要:
A low profile, flexible windshield wiper assembly has a frame (10) constructed from flat sheet spring steel. The frame (10) attaches to a semi-rigid spline (50) at distinct pressure points, while the spline (50) supports a rubber wiping blade (60). At least some of the pressure points are located at the end of cantilevered fingers (18) formed in the frame (10) so that the spline (50) may flex independently from the frame (10). The cantilevered fingers (18) allow semi-pivotable portions of the frame to flex independently from the rest of the frame to enhance curve conformance on a windshield. The frame (10) attaches along the center of the spline (50) while the blade (60) attaches along the edges of the spline (50). The present invention allows the pressure points to be efficiently formed out of the frame material.
