Abstract

A windshield wiper assembly for a vehicle includes a wiper motor. The wiper motor has a housing having a top surface and a side surface, a projection projecting from the top surface, a mounting bracket integrally extending from the side surface, and a rib integrally extending from the top surface and between the projection and a longitudinal end of the mounting bracket. Advantageously, the rib enhances the robustness of the housing so that it is more tolerant of stresses experienced during use.

First claim

What is claimed is:

1. A windshield wiper assembly, comprising:
a housing having a top surface and a side surface;
a projection projecting in a first direction from the top surface, the projection having a through hole at a center of the projection, a longitudinal axis of the through hole being parallel to the first direction;
a mounting bracket integrally extending from the side surface, the mounting bracket having:
a first end boated at the side surface, the first end having:
a first top end surface; and
first and second longitudinal end surfaces opposite to each other;

a second end located away from the side surface, the second end having:
a second top end surface; and
the first and second on longitudinal end surfaces; and

a semi-cylindrical bottom connecting between the first and second ends, the semi-cylindrical bottom including the first and second longitudinal end surfaces; and

a first rib integrally extending from the top surface in the first direction, the first rib integrally extending from a side of the projection to the first top end surface and the first longitudinal end surface of the mounting bracket in a first rib extending direction,
wherein the rib has a constant height relative to the top surface from the side of the projection to the mounting bracket.

2. The windshield wiper assembly according to claim 1 ,
wherein the first rib has a planar top surface.

3. The windshield wiper assembly according to claim 1 ,
wherein the first rib has a top planar surface that has an equal height with the first top end surface of the mounting bracket relative to the top surface.

4. The windshield wiper assembly according to claim 1 ,
wherein the first rib curves between the side of the projection and the mounting bracket in a plan view.

5. The windshield wiper assembly according to claim 1 ,
wherein the first rib has first and second rib side surfaces, and the first rib side surface is coextensive with the first longitudinal end surface of the mounting bracket.

6. The windshield wiper assembly according to claim 5 ,
wherein the first rib side surface has a rib bottom end surface, the first rib side surface extends in a second direction from the top surface of the housing so that the rib bottom end surface is shallower than the top surface of the housing.

7. The windshield wiper assembly according to claim 6 ,
wherein the rib bottom end surface is perpendicular to the longitudinal axis of the through hole of the projection.

8. The windshield wiper assembly according to claim 7 ,
wherein the rib end surface is shallower than the semi cylindrical bottom of the mounting bracket.

9. The windshield wiper assembly according to claim 1 , further comprising:
an opposite rib integrally extending from the top surface of the housing in the first direction, the opposite rib integrally extending from the side of the projection in an opposite rib extending direction opposite to the first rib extending direction.

10. The windshield wiper assembly according to claim 9 ,
wherein the opposite rib has a top surface in a common plane with a top surface of the first rib.

11. The windshield wiper assembly according to claim 1 ,
wherein the first rib extends to a housing bottom end of the side surface of the housing.

12. The windshield wiper assembly according to claim 1 ,
wherein the mounting bracket is mounted to a bar so that the semi-cylindrical bottom of the mounting bracket abuts the bar.
