Abstract

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.

Claims

7. A wiper blade comprising:

a wiper strip,

a primary frame, having a top side and opposite ends, a connection device capable of connecting the wiper blade to a wiper arm disposed on the top side of the primary frame, and a connection structure disposed on each of the opposite ends of the primary frame;

a pair of secondary frames, each having a pivot connection portion and two leg portions extending from the pivot connection portion, a pivot structure disposed on the central pivot connection portion of the secondary frames;

wherein the pivot structures disposed on the secondary frames are connected to the connection structures on the ends of the primary frame; and

two pairs of tertiary frames, each pair of tertiary frames pivotally connected to a corresponding end of each of the two leg portions of each secondary frame.

8. The wiper blade of claim 7, wherein each of the secondary frames is a thin bracket having a thickness, defined as the distance from a top surface to an opposed bottom surface, substantially less than a width, defined as the distance between opposed side surfaces.

9. The wiper blade of claim 8, further comprising a stiffing bead provided on the top surface of each of the secondary frames.

10. The wiper blade of claim 9, wherein the stiffing beads has a thickness, defined as the distance between the secondary frame'"'"'s top surface and a top surface of the stiffing bead, which is greater than the thickness of the secondary frame.

11. The wiper blade of claim 9, wherein each stiffing bead is provided along the top surface of one of the leg portion and the central pivot portion.

12. The wiper blade of claim 8 wherein the thickness of the secondary frames is substantially constant along the length of each secondary frame.

16-1. The wiper blade of claim 1 wherein the two leg portions of each of the secondary frames has a different angle of descent.
