ABSTRACT:
Provided is a rubber blade for an automotive wiper capable of autonomously pressing firmly and resting securely against a windshield surface by altering the structure of the rubber blade. The rubber blade has a head portion forming an upper portion of the rubber blade. The head portion includes a pair of mounting slots for mounting the rubber blade along a wiper frame. The pair of mounting slots has a sectional offset angle (θ1), dependant on the disposition of the wiper frame. A central axis in a center between the pair of mounting slots in a sectional view of the blade is offset by an angle (θ3) from a vertical axis (L1). A wiping portion forms a lower portion of the rubber blade for contacting the windshield, and is disposed in the direction of the vertical axis (L1).
