Abstract
The present invention discloses a wiper blade, comprising a frame type long strip skeleton, a connector to be connected to a wiper arm of an automobile and a rubber strip. The skeleton includes one elastic main beam. The body of the main beam has a curved locus, continuous concave downward curve, both end portions of the main beam register with the curved locus and a middle portion of the main beam registers with or deviates from the curved locus. The skeleton includes one or two elastic sub beams, located below and approximately parallel to the main beam which supports the rubber strip. Between the main beam and the sub beams is a means to constitute various frame structures or to adjust a distance between them so that the pressure applied along the entire length of the wiper blade to a windshield can be distributed evenly as far as possible.
