Abstract

A windshield wiper arm mount has a cross bar. An arm mount lock locks the cross bar to a wiper arm. A mount block is provided. A pair of similarly configured backing strips are coupled to a strengthening rib, a coupling component, a first wiper component, and a second wiper component. The first wiper component is a rubber strip to wipe the windshield and the second wiper component has an abrasive quality to help clean debris from the windshield. A pair of end caps hold the components together.

13. A windshield wiper system as described in claim 12 wherein the rib has a third length with the rib having a slot between the upper and lower surfaces running along the length of the rib from a location adjacent to an end edge to the a location adjacent at the opposing end edge.

14. A windshield wiper system as described in claim 13 wherein the rib further comprises the slot having an enlarged slot area at both ends of the slot, the rib having a plurality of fastening apertures there through with the fastening apertures of the rib being configured to mate with the fastener apertures of the mount block.

15. A windshield wiper system as described in claim 1 wherein the system further comprises a plurality of fasteners to couple the rib and the mount block together.

16. A windshield wiper system as described in claim 1 with the coupling component of the upper portion having a generally T-shaped configuration of a fourth length, the fourth length being less than the third length, the upper portion having a horizontal upper end and a vertical lower end having a groove.

17. A windshield wiper system as described in claim 1 wherein the lower portion of the coupling component comprises a pair of like-configured parallel generally C-shaped receiving surfaces of a third length.

18. A windshield wiper system as described in claim 1 wherein the first wiper component is fabricated of a resilient material having a T-shaped upper portion configured to be received by and mate the coupling component.

19. A windshield wiper system as described in claim 1 wherein the second wiper component is fabricated of a resilient material, the second wiper component having a T-shaped upper portion configured to be received by and mate with the coupling component.

20. A windshield wiper system as described in claim 1 with the open end of the end cap being configured to mate with and receive the backing strip and the rib and the lower coupling component so as to couple the backing strip and the rib and the lower coupling component together.
