Abstract

A windshield wiper assembly includes a pair of leaf spring elements supported generally parallel to each other with a space therebetween, a flexible blade supported within the space between the leaf spring elements, a bracket fixed to the intermediate portion of the pair of leaf spring elements and supporting said pair of leaf spring elements to provide the space therebetween, the bracket including a pair of pressure distribution tabs, and a bracket cover connected at opposite sides of the bracket, the bracket cover having a skirt extending below the bracket to cover a portion of the pair of leaf spring elements at the intermediate portion.

Claims

1. A windshield wiper assembly, comprising:

a pair of leaf spring elements supported generally parallel to each other with a space therebetween, each leaf spring element including a locating hole at an intermediate portion thereof;

a flexible blade supported within the space between the leaf spring elements;

a bracket fixed to the intermediate portion of the pair of leaf spring elements and supporting said pair of leaf spring elements to provide the space therebetween, the bracket including a pair of pressure distribution tabs, each pressure distribution tab extending from opposite sides of the bracket, each pressure distribution tab being received in a corresponding one of the locating holes of the pair of leaf spring elements to locate the bracket at the intermediate portion of the pair of leaf spring elements; and

a bracket cover connected at opposite sides of the bracket, the bracket cover having a skirt extending below the bracket to cover a portion of the pair of leaf spring elements at the intermediate portion.

2. The wiper assembly according to claim 1, wherein the bracket cover includes a pair of spoiler restraining portions at opposite ends thereof.

3. The wiper assembly according to claim 2, further comprising at least one spoiler connected to the pair of leaf spring elements, the spoiler extending in an opposite direction from the blade, and an end of the spoiler being received in one of the pair of spoiler restraining portions.

4. The wiper assembly according to claim 1, wherein the bracket includes at least one cut-out formed in each of said opposite sides, and

wherein the bracket cover includes at least one tab extending from opposite sides thereof, each of the at least one tabs extending towards and being received in one of the corresponding cut-outs of the bracket.

5. The wiper assembly according to claim 4, wherein the at least one cut-out includes a pair of cut-outs formed in each of said opposite sides, and

wherein the at least one tab includes a pair of tabs extending from each of said opposite sides of the bracket cover, each tab extending towards and received in one of the cut-outs of the bracket.

6. A windshield wiper assembly, comprising:

a pair of leaf spring elements supported generally parallel to each other with a space therebetween, each leaf spring element including a locating hole at an intermediate portion thereof;

a flexible blade supported within the space between the leaf spring elements;

a bracket fixed to the intermediate portion of the pair of leaf spring elements and supporting said pair of leaf spring elements to provide the space therebetween, the bracket including a pair of pressure distribution tabs, each pressure distribution tab extending from opposite sides of the bracket, each pressure distribution tab being received in a corresponding one of the locating holes of the pair of leaf spring elements to locate the bracket at the intermediate portion of the pair of leaf spring elements; and

at least one spoiler having a first end connected to the pair of leaf spring elements, the spoiler extending in an opposite direction from the blade to form a second end.

7. The wiper assembly according to claim 6, wherein the at least one spoiler is symmetrical about a plane passing through the center of the spoiler.

8. The wiper assembly according to claim 7, wherein the at least one spoiler includes a protuberance at the second end.

9. A windshield wiper assembly, comprising:

a pair of leaf spring elements supported generally parallel to each other with a space therebetween;

a flexible blade supported within the space between the leaf spring elements; and

a bracket fixed to an intermediate portion of the pair of leaf spring elements and supporting said pair of leaf spring elements to provide the space therebetween, the bracket including;

a base portion fixed to the pair of leaf spring elements;

a pair of side walls extending upward from the base portion, each side wall including a first through hole located substantially in the center of the bracket; and

a post extending between the pair of side walls, the post and the first through hole being substantially aligned along a straight line perpendicular to the pair of leaf spring elements.

10. The wiper assembly according to claim 9, wherein each side wall includes a second through hole located above and off-center from the first through hole.
