Windscreen wiper device

1. A windscreen wiper device for cleaning a windshield of a vehicle, comprising:

an elongated wiper strip of a flexible material for sealing against the windshield;

a carrier element extending between opposite end portions and supporting said elongated wiper strip to bias said elongated wiper strip into a predetermined configuration;

a frame structure including a main bridge and a pair of generally V-shaped linkages which each have a plurality of claws in engagement with said carrier elements between said end portions for biasing a portion of said wiper strip against the windshield and also including at least two end caps slidably supporting said end portions of said at least one carrier element;

wherein said end caps are operably coupled with said main bridge of said frame structure at pivoting locations which are spaced from said V-shaped linkages for allowing said end caps to pivot relative to said main bridge and wherein at least said end portions of said at least one carrier element are curved when in a relaxed state to bias said wiper strip against the windshield; and

each of said end piece sub-assemblies further including a connecting piece which is formed as a separate piece from said main bridge and said end cap and said linkage and which operably couples said linkage and said end cap with said main bridge.

2. The windscreen wiper device as set forth in claim 1 wherein said frame structure further includes a pair of end piece sub-assemblies coupled to opposite ends of said main bridge and wherein said end caps are in said end piece sub-assemblies.

3. The windscreen wiper device as set forth in claim 2 wherein each of said end caps includes at least one holding element wrapping partially around said carrier element.

4. The windscreen wiper device as set forth in claim 3 wherein said at least one holding element is further defined as a pair of holding elements.

5. The windscreen wiper device as set forth in claim 4 wherein said holding elements are generally L-shaped.

6. The windscreen wiper device as set forth in claim 2 wherein each of said end piece sub-assemblies also includes one of said linkages with at least one set of said claws in engagement with said carrier element.

7. The windscreen wiper device as set forth in claim 6 wherein said sets of claws are in sliding engagement with said carrier element to allow said carrier element to slide in a lengthwise direction relative to said V-shaped linkages.

8. The windscreen wiper device as set forth in claim 7 wherein each of said end caps further includes a downwardly extending flange portion disposed next to adjacent ends of said carrier element to establish confines for restricting the movement of said carrier element and said wiper strip relative to said frame structure in said lengthwise direction.

9. The windscreen wiper device as set forth in claim 1 wherein said connecting piece of each end piece sub-assembly includes sets of apertures for receiving posts on said end cap and said linkage to establish pivoting relationships between said end cap and said connecting piece and between said linkage and said connecting piece.

10. The windscreen wiper device as set forth in claim 9 wherein each of said connecting pieces is generally U-shaped as viewed in cross-section with a pair of side walls and an upper wall.

11. The windscreen wiper device as set forth in claim 10 wherein said apertures on said connecting pieces are on said side walls.

12. The windscreen wiper device as set forth in claim 10 wherein each of said connecting pieces includes a spring loaded tab on its upper wall for snapping into engagement with said main bridge.

13. A windscreen wiper device for cleaning a windshield of a vehicle, comprising:

an elongated wiper strip of a flexible material for sealing against the windshield;

a carrier element extending between opposite end portions and in engagement with said elongated wiper strip to bias said elongated wiper strip into a predetermined configuration;

a frame structure including a plurality of claws in engagement with said carrier element between said end portions for biasing a portion of said wiper strip against the windshield and also including at least two end caps slidably supporting said end portions of said carrier element;

wherein said frame structure includes a main bridge and a pair of end piece sub-assemblies coupled to opposite ends of said main bridge and wherein said end caps are in said end piece sub-assemblies;

wherein each of said end piece sub-assemblies includes a generally V-shaped linkage and said end cap and a connecting piece which is made as a separate piece from said linkage and said end cap and said main bridge and which interconnects said linkage and said end cap with said main bridge;

wherein said connecting piece of each end piece sub-assembly includes sets of apertures for receiving posts on said end cap and said V-shaped linkage to establish pivoting relationships between said end cap and said connecting piece and between said linkage and said connecting piece;

wherein each of said connecting pieces is generally U-shaped as viewed in cross-section with a pair of side walls and an upper wall; and

wherein said end caps are operably coupled with said main bridge of said frame structure via said connecting pieces at pivoting locations which are spaced from said V-shaped linkages for allowing said end caps to pivot relative to said main bridge and wherein at least said end portions of said carrier element are curved when in a relaxed state to bias said wiper strip against the windshield wherein each of said end caps includes a tongue extending outwardly and presenting said posts to establish said pivoting relationship between said end cap and said connecting piece.

14. The windscreen wiper device as set forth in claim 1 wherein said carrier element is generally linearly shaped between said curved end portions when said carrier element is in said relaxed state.
