Abstract:
1. A wiper comprising: a blade member; a flat tension spring frame on which the blade member is disposed; and an adapter configured to join the flat tension spring frame with an automotive wiper arm, wherein the blade member comprises: a head portion forming an upper portion of the blade member and including a pair of substantially uniform width mounting slots adapted to receive the flat tension spring frame therein, the mounting slots defining a first reduced width portion therebetween, the mounting slots further defining a first transverse axis passing centrally therethrough, a second transverse axis extends perpendicular to said first transverse axis and passes substantially through a center of said first reduced width portion; and a wiping portion, forming a lower portion of the blade member, contacting a windshield at a tip end thereof and including a second reduced width portion coupled with the head portion, wherein the head portion and wiping portion together define a blade member profile wherein a vertical axis passes substantially centrally through both reduced width portions and said tip end, said second transverse axis extending at an offset angle with respect to the vertical axis and intersecting the vertical axis at a point between said mounting slots within said first reduced width portion, said first transverse axis being inclined with respect to the windshield so that the flat tension frame of the wiper acts as a spoiler; and the blade member is held to retain the profile in disposition of substantially 90 degrees with respect to the windshield.
