The invention claimed is: 1. A member for insertion into a hollow structure of an automotive vehicle, comprising: at least two interconnected segments each segment comprising a support member defining an internal cavity within the support member and containing a foamable material within said cavity

The invention claimed is: 1. A member for insertion into a hollow structure of an automotive vehicle, comprising: at least two interconnected segments each segment comprising a support member defining an internal cavity within the support member and containing a foamable material within said cavity, the segments being connected in a manner that enables flexible movement of the segments relative to each other, the segments being relatively thin for allowing insertion of the segments into a narrow gap of the hollow structure and in which a plate is provided in the cavity which supports the foamable material within the cavity. 2. A member according to claim 1, wherein the cavity within the support member contains ribs which define spaces for and support of the foamable material. 3. A member according to claim 2, in which the foamable material fills the spaces defined by the ribs. 4. A member according to claim 1, in which the plate is integral with the ribs so that the ribs and the plate provide a structure within the cavity which supports the foamable material and directs the foamable material during foaming. 5. A member according to claim 1, provided with clips to enable it to be attached to the surface of the structure. 6. A member according to claim 1 in which at least part of the internal walls of the support member, which define the cavity, are provided with an internally facing lip which supports the foamable material and supports and directs the material as it foams. 7. The member of claim 1, wherein the interconnected segments are made of a metal. 8. A member according to claim 1 wherein the at least two interconnected segments are interconnected with a flexible interconnecting element. 9. A member according to claim 8 wherein the at least two interconnected segments include at least three interconnected segments flexibly interconnected with flexible interconnecting elements. 10. A member according to claim 9 wherein the support members of each of the segments substantially surround the foamable material within the cavities of the segments. 11. A member according to claim 10 wherein the foamable material is substantially dry and non-tacky to the touch. 12. A member according to claim 11 wherein the support member of each of the at least three interconnected segments is formed of a polyamide. 13. A member according to claim 12 wherein the at least three interconnected segments are adapted for insertion into a contoured pillar of an automotive vehicle by virtue of the flexible movement of the interconnected segments relative to each other. 14. A member for insertion into a hollow structure of an automotive vehicle, comprising: at least three segments that are made of a material selected from metal or plastic, each segment supporting a foamable material, and being connected in a manner that enables flexible movement of the segments relative to each other, a flexible interconnecting element located between the segments and linking the segments, at least one clip adapted for attaching the member to a surface, wherein the member is adapted for structural reinforcement, noise abatement, or a combination thereof. 15. The member of claim 14, wherein the segments include ribs for supporting the foamable material. 16. The member of claim 14, wherein the foamable material is disposed in a cavity defined in the segments. 17. The member of claim 14, wherein prior to activation for foaming, is dry and not tacky to the touch. 18. A member according to claim 14 wherein: i. the foamable material expands and forms a foam at temperatures experienced in a bake oven of an e-coat process for an automotive vehicle; and ii. the support members are formed of a thermoplastic. 19. A member for insertion into a hollow structure of an automotive vehicle, comprising: at least two interconnected segments each segment comprising a support member defining an internal cavity within the support member and containing a foamable material within said cavity, the segments being connected in a manner that enables flexible movement of the segments relative to each other, the segments being relatively thin for allowing insertion of the segments into a narrow gap of the hollow structure and in which at least part of the internal walls of the support member, which define the cavity, are provided with an internally facing lip which supports the foamable material and supports and directs the material as it foams. 20. A member according to claim 19, wherein the cavity within the support member contains ribs that support the foamable material and which define spaces in which the foamable material is located. 21. A member according to claim 20, in which a plate is provided in the cavity which supports the foamable material and in which the plate is integral with the ribs so that the ribs and the plate provide a structure within the cavity which supports the foamable material and directs the foamable material during foaming. 22. A member according to claim 19, provided with clips to enable it to be attached to the surface of the structure. 23. A member according to claim 19 wherein the member is configured to provide clearance between the external surface of the member and the internal surface of a hollow structure when located within the hollow structure. 24. A member according to claim 19 wherein the foamable material is configured to foam in a drying oven that dries electrocoat. 25. A member according to claim 19 wherein the foamable material is configured to foam in a drying oven that dries electrocoat. 26. A member for location within an automotive vehicle, comprising: at least two interconnected segments each segment comprising a support member defining a cavity within the support member and containing a foamable material within said cavity wherein: i. the segments are connected by a flexible interconnecting member in a manner that enable flexible movement of the segments relative to each other by bending or flexing of the flexible interconnecting member; ii. the cavity within at least one of the support members contains ribs that support the foamable material and that define spaces in which the foamable material is located. 27. A member according to claim 26 in which a small plate is provided in the cavity which supports the foamable material within the cavity. 28. A member according to claim 26 in which the plate is integral with the ribs so that the ribs and the plate provide a structure within the cavity which supports the foamable material and directs foamable material during foaming. 29. A member according to claim 26 in which the member includes a clip attached to at least one of the at least two segments. 30. A member according to claim 26 wherein the segments are located within a hollow structure of an automotive vehicle. 31. A member according to claim 30 wherein the flexible interconnecting member flexes about a contour defined by the structure. 32. A member according to claim 26 wherein clips attach the segments to a structure of an automotive vehicle. 33.
