Wiper blade
First Claim
1. A wiper blade comprising:
- a wiper strip,a primary frame, having a top side oriented away from the wiper strip, 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 top surface oriented away from the wiper strip and a bottom surface oriented towards the wiper strip, each having a pivot connection portion and two leg portions, wherein each leg portion is straight and extends from the pivot connection portion at an oblique angle of descent relative to the pivot connection portion, a pivot structure disposed on the central pivot connection portion of the secondary frames, wherein each leg portion is thin and has a cross-section with a substantially rectangular shape having the thickness of the pivot connection portion, wherein the cross-section is made by a vertical plane;
wherein the pivot structures disposed on the secondary frames are connected to the connection structures on the ends of the primary frame.

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.
