A wiper blade is presented having a wiper strip, a primary frame, and a pair of secondary frames. The primary frame having a connection device capable of connecting the wiper blade to a wiper arm disposed on a top side of the primary frame, and a connection structure disposed, on opposite ends of the primary frame. The pair of secondary frame, each have a central pivot connection portion and two leg portions extending from the central pivot connection portion, a pivot structure disposed on the central pivot connection portion of the secondary frames wherein the pivot structure of the secondary frames are connected to the connection structures on the ends of the primary frame. A wiper blade is also presented having a wiper strip, a force distribution structure having opposite ends, and a cover.
1. A wiper blade comprising:
a wiper strip;
a force distribution structure separate from the wiper strip, having opposing ends, and comprising one or more beams and/or brackets, the force distribution structure securing the wiper strip;
a connection device capable of connecting to a wiper arm of a vehicle as the connection device disposed on the force distribution structure and
a cover separate from the wiper strip and force distribution structure, the cover secured to and covering the force distribution structure, comprising a cover center section having two end portions and two cover side sections, wherein the cover side sections have side walls and a bottom surface that define a U-shape and each of the cover side sections cover one of the end portions of the cover center section and extend to and cover one of the opposing ends of the force distribution structure;
wherein the cover center section comprises one or more internal grips provided on an inner surface of the cover that grip the force distribution structure; and
wherein each cover side section further comprises one or more internal grips provided on an internal surface of each of the side sections that grip the force distribution structure; and wherein each cover side section includes a protrusion inserting into a hole of a tab of the cover center section, and each tab extends from a terminal end surface of the cover center section.
2. The wiper blade of claim 1 , wherein the side sections have a Shore hardness value at or between 60 and 90, and the center section has a Shore hardness value at or above 90.
3. The wiper blade of claim 1 , wherein the one or more internal grips on the inner surface of the cover side sections include a claw.
4. The wiper blade of claim 1 further comprising the one or more internal grips provided on an inner surface of the center section of the cover, wherein the one or more internal grips grip the force distribution structure.
5. The wiper blade of claim 1 , wherein each end of the force distribution structure is a chamfered “T” structure, and the one or more internal grips of the cover side sections include an end grip with a slotted pocket; wherein the chamfered “T” structures of the ends of the force distribution structure are disposed within the slotted pockets of the cover side sections.
6. The wiper blade of claim 1 wherein the side connecting structures on the end portions of the cover center section comprise bottom projections which grip a corresponding recess or hole in the side receiving structures in the cover side sections.
7. The wiper blade of claim 1 wherein the cover side sections further comprise a spoiler.
8. The wiper blade of claim 1 wherein the cover side sections further comprise a spoiler.
9. A wiper blade comprising:
a wiper strip;
a force distribution structure separate from the wiper strip, having opposite ends, and comprising one or more beams, and/or brackets, the force distribution structure securing the wiper strip;
a connection device capable of connecting to a wiper arm of a vehicle as the connection device is disposed on the force distribution structure; and
a cover separate from the wiper strip and force distribution structure, the cover secured to and covering the force distribution structure, comprising a cover center section having two end portions and two cover side sections, wherein the cover side sections have side walls and a bottom surface that define a U-shape and each of the cover side sections cover one of the end portions of the cover center section and extend to and cover one of the opposing ends of the wiper blade,
wherein each cover side section further comprises one or more internal grips provided on an inner surface of each of the side sections that grip the force distribution structure; and wherein each cover side section includes a protrusion inserting into a hole of a tab of the cover center section, and each tab extends from a terminal end surface of the cover center section.
10. The wiper blade of claim 9 , wherein each end of the force distribution structure is a chamfered “T” structure, and the one or more internal grips include an end grip with a slotted pocket for receiving one of the ends of the force distribution structure.
11. The wiper blade of claim 9 wherein the one or more internal grips on the inner surface of the cover side sections include a claw.
12. The wiper blade of claim 9 wherein side connecting structures on the end portions of the cover center section comprise bottom projections which grip a corresponding recess or hole in side receiving structures in the cover side sections.
