Windscreen wiper device

1. A windscreen wiper device, comprising:

a longitudinally extending wiper element made of an elastomeric material;

a carrier element including at least one pre-curved longitudinal strip operably supporting said wiper element;

a connector device with a first piece and a second piece; and

a joint part which is connectable to said second piece of said connector device and is configured for attachment with an oscillating wiper arm;

said second piece including a pair of prongs which extend through aligned openings in said first piece and said at least one pre-curved longitudinal strip, a first portion of said prongs extending at an angle relative to a second portion of said prongs, wherein said second piece of said connector device has a pair of co-axially aligned protrusions that are received in co-axially aligned openings in said joint part to allow said joint part to pivot relative to said connector device;

said pair of prongs being plastically deformed to lock and fasten said first and second pieces of said connector device with said at least one pre-curved longitudinal strip.

2. The windscreen wiper device as set forth in claim 1 , wherein said first piece of said connector device is made of plastic and wherein said second piece of said connector device is made of metal.

3. The windscreen wiper device as set forth in claim 1 , wherein ends of said prongs are plastically deformed in laterally outward directions.

4. The windscreen wiper device as set forth in claim 1 wherein said second piece of said connector device includes a pair of generally J-shaped side walls that are spaced apart from one another in a lateral direction.

5. The windscreen wiper device as set forth in claim 4 wherein each of said J-shaped side walls has a lower edge that is received in a slot on said first piece of said connector device.

6. The windscreen wiper device as set forth in claim 1 wherein said first portion of said prongs extends substantially perpendicular to said second portion of said prongs.

7. The windscreen wiper device as set forth in claim 1 wherein said pair of prongs are substantially L-shaped.

8. The windscreen wiper device as set forth in claim 1 wherein ends of said prongs are plastically deformed in laterally inward directions.

9. A windscreen wiper device, comprising:

a longitudinally extending wiper element made of an elastomeric material;

a carrier element including at least one pre-curved longitudinal strip operably supporting said wiper element;

a connector device with a first piece and a second piece; and

a joint part which is connectable to said second piece of said connector device and is configured for attachment with an oscillating wiper arm;

said second piece including a pair of prongs which extend through aligned openings in said first piece and said at least one pre-curved longitudinal strip, a first portion of said prongs extending at an angle relative to a second portion of said prongs;

said pair of prongs being plastically deformed to lock and fasten said first and second pieces of said connector device with said at least one pre-curved longitudinal strip, wherein ends of said prongs are plastically deformed in laterally outward directions.

10. The windscreen wiper device as set forth in claim 9 wherein said first piece of said connector device is made of plastic and wherein said second piece of said connector device is made of metal.

11. The windscreen wiper device as set forth in claim 9 wherein said second piece of said connector device includes a pair of generally J-shaped side walls that are spaced apart from one another in a lateral direction.

12. The windscreen wiper device as set forth in claim 11 wherein each of said J-shaped side walls has a lower edge that is received in a slot on said first piece of said connector device.

13. The windscreen wiper device as set forth in claim 9 wherein said first portion of said prongs extends substantially perpendicular to said second portion of said prongs.

14. The windscreen wiper device as set forth in claim 9 wherein said pair of prongs are substantially L-shaped.

15. A windscreen wiper device, comprising:

a longitudinally extending wiper element made of an elastomeric material;

a carrier element including at least one pre-curved longitudinal strip operably supporting said wiper element;

a connector device with a first piece and a second piece; and

a joint part which is connectable to said second piece of said connector device and is configured for attachment with an oscillating wiper arm;

said second piece including a pair of prongs which extend through aligned openings in said first piece and said at least one pre-curved longitudinal strip, a first portion of said prongs extending at an angle relative to a second portion of said prongs;

said pair of prongs being plastically deformed to lock and fasten said first and second pieces of said connector device with said at least one pre-curved longitudinal strip, wherein ends of said prongs are plastically deformed in laterally inward directions.

16. The windscreen wiper device as set forth in claim 15 wherein said first piece of said connector device is made of plastic and wherein said second piece of said connector device is made of metal.

17. The windscreen wiper device as set forth in claim 15 wherein said second piece of said connector device includes a pair of generally J-shaped side walls that are spaced apart from one another in a lateral direction.

18. The windscreen wiper device as set forth in claim 17 wherein each of said J-shaped side walls has a lower edge that is received in a slot on said first piece of said connector device.

19. The windscreen wiper device as set forth in claim 15 wherein said first portion of said prongs extends substantially perpendicular to said second portion of said prongs.

20. The windscreen wiper device as set forth in claim 15 wherein said pair of prongs are substantially L-shaped.
