Claims5
A windshield wiper blade for vehicles, comprising:
- a wiper element having a lip and a base portion;
- a wiper holder having a longitudinal groove that receives and restrains the base portion of said wiper element and which has a longitudinal cavity;
- a metal reinforcing core disposed in the longitudinal cavity;
- and
- an arcuate support structure with restraining jaws that grip the wiper holder at predetermined points,
- wherein the wiper holder has two longitudinal lateral grooves that are engaged by restraining jaws of the support structure, and
- wherein at least two restraining jaws of the support structure exert on the wiper holder a clamping force which deforms the holder such that the holder also clamps the wiper element.
