Abstract

A member forming a support for a device includes a mass of rubber delimited by two substantially parallel opposite surfaces forming respectively a supporting surface and a surface for connection with a tyre. The mass includes an opening arranged in the connecting surface delimiting a recess arranged in the mass, and the opening does not lead to outside of the connecting surface.

Claims

1-12. -12. (canceled)

13. Member forming a support for a device, comprising a mass of rubber delimited by two substantially parallel opposite surfaces forming respectively a supporting surface and a surface for connection with a tyre, the mass comprising an opening arranged in the connecting surface delimiting a recess arranged in the mass and the opening not leading to the outside of the connecting surface.

14. Member according to claim 13, in which the supporting surface extends at least partially in line with the surface of the opening.

15. Member according to claim 13, in which the orthogonal projection of the supporting surface on the connecting surface coincides substantially with the opening arranged in the connecting surface.

16. Member according to claim 13, in which the ratio between the depth of the recess and the distance between the two surfaces, the supporting surface and the connecting surface, is between ¼

and ½

, preferably substantially equal to ⅜

.

17. Member according to claim 13, in which the ratio between the surface of the opening and the surface of the mass of rubber in contact with the connecting surface is between 0.15 and 0.30.

18. Member according to claim 13, comprising a channel arranged in the mass and leading to both the supporting surface and to the bottom of the recess.

19. Member according to claim 13, in which the peripheral edge of the member is delimited by a joining surface of opposite surfaces converging on their joining surface at an angle of between 9 and 15 degrees, preferably between 10 and 12 degrees.

20. Member according to claim 19, in which the joining surface of the peripheral edge is substantially a joining line.

21. Member according to claim 19, in which the joining surface of the peripheral edge is normal to the connecting surface and has a height of between 0.1 and 0.2 mm.

22. Member according to claim 21, in which the peripheral edge also comprises a cord of substantially rectangular section of the same thickness as the joining surface and extending outwards from 0 to 1.5 mm.

23. Member according to claim 13, in which the member also comprises a layer of connecting rubber placed on the connecting surface without overlapping in line with the peripheral edge of the member.

24. Member according to claim 13, wherein the member is incorporated in a tyre.
