Patent ID: 8042878

Claim:
An interface disc for a vehicle wheel, comprising: a. at least one attachment element by which said disc attaches to a vehicle wheel; b. a plurality of substantially rigid radial arms connected to the at least one attachment elements and extending radially outwards from the at least one attachment element; c. an energy absorption surface collaborating with said substantially rigid radial arms and extending circumferentially in the space defined between the substantially rigid radial arms, wherein the energy absorption surface is a substantially solid screen that is undeformed in a rest position so that the energy absorption surface and the radial arms together form an annular ring in the rest position, and that is flexible and more deformable than the substantially rigid radial arms so that the energy absorption surface deforms from the rest position under the effect of energy released from a rapid loss of pressure from a tire attached to the vehicle wheel and so that this deformation partially or wholly absorbs this energy; d. at least one circumferential reinforcing element of substantially annular shape collaborating with the set of arms and the elastic modulus of which is substantially higher than that of the energy absorption surface.
