2. The assembled component of claim 1 , wherein said lower flitch ( 6 ) is welded to said upper flitch ( 7 ) at the joining points ( 15 , 15 ′).

3. The assembled component of claim 2 , wherein the joining points ( 15 , 15 ′) are disposed at respective opposing portions of said lower flitch ( 6 ) and said upper flitch ( 7 ).

4. The assembled component of claim 2 , wherein said lower flitch ( 6 ) defines a plurality of elongated longitudinally extending ribs ( 9 , 9 ′, 10 ).

5. The assembled component of claim 4 , wherein each of the plurality of ribs defines a respective one of the joining points ( 15 , 15 ′).

6. The assembled component of claim 1 , wherein the joining points ( 15 , 15 ′) are disposed at respective opposing portions of said lower flitch ( 6 ) and said upper flitch ( 7 ).

7. The assembled component of claim 6 , wherein the at least one opening of the intercalation ( 8 ) is a slit.

8. The assembled component of claim 1 , wherein said intercalation ( 8 ) defines a plurality of elongated longitudinally extending openings.

9. The assembled component of claim 8 , wherein the plurality of openings and the at least one opening are slits ( 12 , 12 ′, 12 ″, 14 ).

10. The assembled component of claim 1 wherein said lower flitch includes additional ribs ( 10 ), wherein said at least one rib and said additional ribs are arranged in a zig-zag pattern.

11. The assembled component of claim 1 , wherein the at least one opening is a slit.

12. The assembled component of claim 1 wherein the at least one groove includes a bottom surface for slidable contact with the bottom portion of the window.

13. The assembled component of claim 1 , wherein said guide groove has a rectilinear longitudinal portion and an arcuate end portion and wherein one or more cleaning holes ( 21 , 22 ) are located in said arcuate end portion.

14. The assembled component of claim 1 , wherein the at least one opening comprises a plurality of slits.

15. The assembled component of claim 1 wherein the lower flitch is connected to a side of the upper flitch which is opposite to the upper substantially horizontal major surface of the upper flitch.

16. The assembled component of claim 1 wherein the guide groove in the upper surface of the upper flitch is a substantially upwardly open U-shaped groove having two substantially vertical sides and a substantially horizontal base.

17. The assembled component of claim 1 , wherein the intercalation ( 8 ) has a bend ( 16 ).

18. An assembled component that supports a movable window of a motor vehicle, the component being attached to a fixed window of the vehicle and the component comprising a lower flitch ( 6 ), an upper flitch ( 7 ) which includes an upper surface entirely defining substantially U-shaped guide grooves configured to support the movable window, said movable window being slidably movable within the grooves, and an intercalation ( 8 ) disposed between the lower flitch ( 6 ) and the upper flitch ( 7 ),

the lower flitch ( 6 ) and the upper flitch ( 7 ) being fixedly connected to and in contact with each other at joining points ( 15 , 41 ), wherein said intercalation ( 8 ) has elongated longitudinally extending slits ( 12 , 12 ′, 12 ″, 14 ) which are penetrated by elongated longitudinally extending rises ( 11 , 11 ′, 11 ″, 13 ) of the lower flitch, which contact the upper flitch to form the joining points ( 15 ).

19. The assembled component of claim 18 , wherein the rises include locating faces ( 23 , 24 ).

20. The assembled component of claim 19 , wherein expansion gaps ( 29 , 30 ) are disposed between the rises ( 11 ′, 11 ″) and the slits.

21. An assembled guide rail component for a sliding window of a motor vehicle, the component comprising a lower flitch ( 6 ), an upper flitch ( 7 ), and an intercalation ( 8 ) disposed between the lower flitch ( 6 ) and the upper flitch ( 7 ),

the lower flitch ( 6 ) and the upper flitch ( 7 ) being directly connected to each other at joining points ( 15 , 15 ′) wherein the upper flitch includes an upper surface which entirely defines at least one guide groove configured to support the sliding window, said window being slidably movable within the at least one groove, wherein said lower flitch ( 6 ) defines at least one rib and the intercalation defines at least one longitudinal opening, wherein the at least one rib extends through the at least one longitudinal opening to engage the upper flitch and form at least one of the joining points, and said component further comprising a catch ( 5 ) that is connected to the assembled component and fixed to the motor vehicle, and said catch having a surface in contact with one of two opposite sides of a stationary window fixed to the motor vehicle and a clip portion engaging the intercalation ( 8 ) and a rear wall ( 37 ) of the lower flitch ( 6 ).
