Abstract:
A wiper blade for a windshield wiper device of a vehicle, with a wind-directing device for amplifying the down-force of a wiper squeegee against a windshield by means of oncoming relative wind, and with a support frame system comprising:an elongate main support having a spine, a rear wall extending an entire length of the spine, and spaced front wall sections located only at selected portions of the spine to define U-shaped transverse cross sections only in regions of a suspension case for a wiper arm and for hinge points of claw supports, said rear wall and said front wall sections being parallel at said U-shaped transverse cross sections, the main support being connectable rotatably around an axis transverse to a longitudinal direction of the wiper blade with a wiper arm and including opposite ends;claw supports connected to the main support through hinge points; anda wind-directing device turned toward the relative wind and mounted on a longitudinal side of the wiper blade and formed on the main support including a spine, said wind-directing device overlying said front wall sections, wherein the wind-directing device emerges from a front edge of the main support spine and extends toward the windshield and against the relative wind, and wherein the wind-directing device, in the longitudinal direction, has opposite ends with cantilevered, elongate wings, which protrude beyond the opposite ends of the main support in the longitudinal direction.
