Abstract

A wiper blade. In one aspect, the wiper blade includes a wiper strip which directly wipes a wiping surface; a lever assembly which supports the wiper strip; and a cover which receives the lever assembly, wherein the lever assembly supports six points of the wiper strip by means of a pair of first levers, each of which supports two points of the wiper strip, and a pair of second levers, each of which is hinge-coupled to the first lever, is coupled to the cover and supports one point of the wiper strip.

Claims

1. A wiper blade comprising:

a wiper strip which directly wipes a wiping surface;

a lever assembly which supports the wiper strip; and

a cover which receives the lever assembly;

wherein the lever assembly supports six points of the wiper strip by means of a pair of first levers, each of which supports two points of the wiper strip; and

wherein a pair of second levers, each of which is hinge-coupled to the first lever, is coupled to the cover and supports one point of the wiper strip.

3. The wiper blade of claim 1, wherein the cover comprises a fixing cover and at least one moving cover which is pivotable with respect to the fixing cover.

4. The wiper blade of claim 3, wherein the moving cover is fixed and coupled to the second lever and is located on both ends of the fixing cover.

5. The wiper blade of claim 1, further comprising a first spacer which is provided in a central portion of the second lever and pressurizes the second lever from the outside of the second lever and is made of a resin material.

6. The wiper blade of claim 5, further comprising a spacer clip which is inserted between the first spacer and the fixing cover, the spacer clip having an arch-shaped cross section and being made of a metallic material.

7. The wiper blade of claim 6, wherein the spacer clip comprises a spacer rib and an elastic latch, wherein the spacer rib allows the spacer clip to be coupled in a sliding manner to a slot formed within the fixing cover, and wherein the elastic latch is caught by an outer end portion of the slot and restrains backward movement of the spacer clip.

8. The wiper blade of claim 1, further comprising a second spacer which is provided in one end of the second lever and pressurizes the first lever and is made of a resin material.

9. The wiper blade of claim 1, wherein an axial direction cross section of a lower space of the second lever has a trapezoidal shape.

10. The wiper blade of claim 1, wherein a distance between first fasteners of the first lever is increased or decreased according to a curvature of the wiping surface.

11. The wiper blade of claim 1, wherein the cover comprises finned sections which form an upper front end of the cover, the finned sections are integrally formed with the cover in such a manner as to be as a whole concave toward the wiper strip.

2. A wiper blade comprising:

a wiper strip which directly wipes a wiping surface;

a lever assembly which supports the wiper strip and comprises two pairs of first levers and a pair of second levers; and

a cover which receives the lever assembly;

wherein the pair of the second levers is coupled to the cover and is hinge-coupled to one of the pair of the first levers; and

wherein each of the two pairs of the first levers supports two points of the wiper strip.

12. A wiper blade comprising:

a wiper strip which directly wipes a wiping surface;

a lever assembly which supports the wiper strip; and

a cover which receives the lever assembly;

wherein a transverse centerline of the lever assembly is offset from a transverse centerline of the wiper strip to the rear side of a vehicle.

13. The wiper blade of claim 12, wherein the cover comprises a fixing cover and at least one moving cover which is pivotable with respect to the fixing cover.

14. The wiper blade of claim 13, wherein the at least one moving cover is fixed and coupled to the second lever and is located on both ends of the fixing cover.

15. The wiper blade of claim 12, wherein the cover comprises finned sections which form an upper front end of the cover and are integrally formed with the cover in such a manner as to be as a whole concave toward the wiper strip.
