Abstract
A winter wiper blade consists of an articulated plastic frame, a rubber boot enclosing the frame and an external wiper blade element. The frame consists of a primary yoke and pairs of pivotable center and end yokes, each having a respective claw thereon for support of a backing strip, in turn slotted to receive the anchoring bead of the rubber wiper element. A pair of end caps, each having spring arms thereon and a further claw are adapted for interlocking engagement in a groove at the outer end of the end yoke to support the tip of the wiper element. Each end cap includes extensive surface area to engage and seal with a conforming shaped end channel portion of the rubber boot. A u-shaped saddle is disposed at the central portion of the primary yoke over the rubber boot for receipt of a wiper motor arm and is uniquely mounted by transverse rivets to facilitate assembly thereof.
