Abstract

A wiper coupler assembly for releasably attaching a wiper assembly to a wiper arm includes a wiper coupler adapted for connection to the wiper assembly and a wiper coupler adaptor connected to the wiper coupler and adapted for connection to an attachment member of the wiper arm. The wiper coupler adaptor includes a pair of sidewalls extending longitudinally and a deck disposed between the sidewalls to define a rest that is adapted to operatively receive a track between rails of the attachment member. Each of the sidewalls includes a post that extends laterally toward the other and disposed in bores of the wiper coupler. Each of the sidewalls includes a retention member extending outwardly and longitudinally therealong adapted to operatively engage a corresponding retention guide in the rails of the attachment member.

Claims

1. A wiper coupler assembly for releasably attaching a wiper assembly to a wiper arm, said wiper coupler adaptor comprising:

a wiper coupler adapted for connection to the wiper assembly;

a wiper coupler adaptor connected to said wiper coupler and adapted for connection to an attachment member of the wiper arm;

said wiper coupler including a base portion adapted for connection to the wiper assembly and an attachment portion extending from said base portion and having a pair of opposed bores extending laterally toward the other;

said wiper coupler adaptor including a pair of sidewalls extending longitudinally and a deck disposed between said sidewalls to define a rest that is adapted to operatively receive a track between rails of the attachment member; and

each of said sidewalls including a post that extends laterally toward the other and disposed in said bores of said wiper coupler, each of said sidewalls including a retention member extending outwardly and longitudinally therealong adapted to operatively engage a corresponding retention guide in the rails of the attachment member.

2. A wiper coupler assembly as set forth in claim 1 wherein said retention member is generally “

V”

shaped.

3. A wiper coupler assembly as set forth in claim 1 wherein said retention member has a leading end and a trailing end, said leading end having a height less than said trailing end.

4. A wiper coupler assembly as set forth in claim 1 wherein said retention member has an upper edge and a lower edge, said upper edge extending linearly and said lower edge extending at an acute angle relative to said upper edge.

5. A wiper coupler assembly as set forth in claim 1 wherein said wiper coupler adaptor includes a snap bridge adapted to be received in an aperture of the attachment member to prevent undesired release of said wiper coupler adaptor from the attachment member.

6. A wiper coupler assembly for releasably attaching a wiper assembly to a wiper arm, comprising:

an attachment member adapted to extend from the wiper arm including a base extending longitudinally and a pair of rails extending longitudinally from said base to define a track, each of said sidewalls including a retention guide extending longitudinally therein;

a wiper coupler adapted for connection to the wiper assembly, said wiper coupler including a base portion adapted for connection to the wiper assembly and an attachment portion extending from said base portion and having a pair of opposed bores extending laterally toward the other; and

a wiper coupler adaptor including a pair of sidewalls extending longitudinally and a deck disposed between said sidewalls to define a rest to operatively receive said track between said rails of said attachment member, each of said sidewalls including a post that extends laterally toward the other and disposed in said bores of said wiper coupler to connect to said wiper coupler, each of said sidewalls including a retention member extending outwardly and longitudinally therealong to operatively engage said retention guide of said attachment member to connect said wiper coupler adaptor to said attachment member.

7. A wiper coupler assembly as set forth in claim 6 wherein said retention guide comprises a slot extending into each of said rails from a free end thereof.

8. A wiper coupler assembly as set forth in claim 7 wherein said slot is generally “

V”

shaped.

9. A wiper coupler assembly as set forth in claim 7 wherein said slot has a leading end and a trailing end, said leading edge having a height greater than said trailing edge.

10. A wiper coupler assembly as set forth in claim 7 wherein said slot has an upper edge and a lower edge, said upper edge extending linearly and said lower edge extending at an acute angle relative to said upper edge.

11. A wiper coupler assembly as set forth in claim 6 wherein said base of said attachment member includes an aperture spaced from a free end thereof.

12. A wiper coupler assembly as set forth in claim 11 wherein said aperture is generally rectangular in shape.

13. A wiper coupler assembly as set forth in claim 11 wherein said wiper coupler adaptor includes a snap bridge disposed in said aperture of said attachment member to prevent undesired release of said wiper coupler adaptor from said attachment member.

14. A wiper coupler assembly as set forth in claim 6 wherein said retention guide is generally “

V”

shaped.

15. A wiper coupler assembly as set forth in claim 6 wherein said retention guide has a leading end and a trailing end, said leading end having a height less than said trailing end.

16. A wiper coupler assembly as set forth in claim 6 wherein said retention guide has an upper edge and a lower edge, said upper edge extending linearly and said lower edge extending at an acute angle relative to said upper edge.

17. A wiper assembly for use in connection with a wiper arm having an attachment member, said wiper assembly comprising:

a wiping element adapted to contact a surface to be wiped;

a support member operatively mounted to said wiping element;

a wiper coupler operatively mounted to said support member; and

a wiper coupler adaptor operatively mounted to said wiper coupler and the attachment member that is adapted to releasably attach said wiper coupler to the attachment member, said wiper coupler adaptor including a pair of sidewalls extending longitudinally, and a deck disposed between said sidewalls to define a rest that is adapted to operatively receive a track between the rails of the attachment member, each of said sidewalls including a post that extends laterally toward the other and disposed in bores of said wiper coupler to connect to said wiper coupler, said sidewalls including a plurality of guide members extending outwardly and longitudinally therealong to operatively engage retention guides of the attachment member to connect said wiper coupler adaptor to the attachment member.

18. A wiper assembly as set forth in claim 17 wherein each of said retention members have a leading end and a trailing end, said leading end having a height less than said trailing end.

19. A wiper assembly as set forth in claim 17 wherein each of said retention members have an upper edge and a lower edge, said upper edge extending linearly and said lower edge extending at an acute angle relative to said upper edge.

20. A wiper assembly as set forth in claim 17 wherein said wiper coupler adaptor includes a snap bridge adapted to be disposed within an aperture of the attachment member to prevent undesired release of said wiper coupler adaptor from the attachment member.

21. A wiper system for a vehicle comprising:

at least one wiper arm adapted to be connected to a source of movement, said at least one wiper arm having an attachment member at a free end thereof, said attachment member comprising a base extending longitudinally and a pair of rails extending longitudinally from said base to define a track therebetween, said rails including retention guides extending longitudinally therein; and

at least one wiper assembly having a wiping element adapted to contact a surface to be wiped, a support member to support said wiping element, a wiper coupler connected to said support member and including a base portion connected to said support member and an attachment portion extending from said base portion and having a pair of opposed bores extending laterally toward the other; and
