1. An aircraft, comprising: at least one floor cross-member of the aircraft;at least one support carrying the cross-member; andat least one bearing including at least one flexible material and connecting the cross-member to the support,the bearing and the flexible material each being fixed to the cross-member,the bearing and the flexible material each being fixed to the support,the cross-member being movable with respect to the support by means of the material deforming,wherein the flexible material is a first material, the bearing includes at least one insert made of a second material interposed between two layers of the first material, the second material being more rigid than the first material. 2. An aircraft according to claim 1, wherein the flexable material is elastic. 3. An aircraft according to claim 1, wherein the or each insert extends over a portion only of a turn around a main axis of the bearing. 4. An aircraft according claim 1, wherein the bearing is configured in such a manner as to present different elasticities in at least two directions that are radial relative to a main axis of the bearing. 5. An aircraft according to claim 1, wherein the bearing presents an annular shape. 6. An aircraft according to claim 1, wherein the bearing presents an axis defined by the annular shape, which axis extends in a horizontal direction perpendicular to a general direction of the cross-member. 7. An aircraft according to claim 1 having two concentric rings between which the bearing is interposed, the rings being connected respectively to the cross-member and to the support, with one of the two rings preferably forming a housing for receiving the bearing. 8. An aircraft according to claim 1, wherein the support comprises a frame connected to the cross-member at at least one end of the cross-member. 9. An aircraft according to claim 1, wherein the support comprises at least one post connected to the cross-member at a distance from the ends of the cross-member. 10. An aircraft according to claim 1, wherein the bearing is arranged to collapse when the intensity of stress on the bearing in a longitudinal direction of the cross-member exceeds a predetermined threshold, said threshold being greater than a threshold predetermined as a maximum for said magnitude under normal circumstances of use of the aircraft. 11. An aircraft according to claim 1, wherein the first material or the second material is an elastomer. 12. An aircraft according to claim 5, wherein the bearing presents a cylindrical shape. 13. An aircraft according to claim 8, wherein the support comprises a frame connected to the cross-member at both ends of the cross-member. 14. An aircraft according to claim 1, further comprising a floor. 15. An aircraft, comprising: at least one floor cross-member of the aircraft;at least one support carrying the cross-member; andat least one bearing including at least one flexable material and connecting the cross-member to the support, the bearing carrying the cross-member, the bearing and the material each being fixed to the support,the cross-member being movable with respect to the support by means of the material deforming,wherein the bearing is a cylindrical annulus with a main section of the bearing being generally U-shaped, with free ends of branches of the U-shaped bearing directed away from a main axis parallel to a longitudinal direction of the aircraft, andwherein the flexible material is a first material, the bearing includes at least one insert made of a second material interposed between two layers of the first material, the second material being more rigid than the first material. 16. An aircraft, composing: at least one floor cross-member of the aircraft;at least one support carrying the cross-member; andat least one bearing including at least one flexible material and connecting the cross-member to the support,the bearing and the flexible material being fixed to the cross-member,the bearing and the flexible material each being fixed to the support,the cross-member being moveable with respect to the support by means of the material deforming,wherein the bearing includes a ring including a plane-shaped cheekplate that closes one of the faces of the ring, the cheekplate fastening the ring to a wall of the support, andwherein the flexible material is a first material, the bearing includes at least one insert made of a second material interposed between two layers of the first material, the second material being more rigid than the first material. 17. An aircraft, comprising: at least one floor cross-member of the aircraft;at least one support carrying the cross-member; andat least one bearing including at least on flexible material and connecting the cross-member to the support,the bearing and the flexible material each being fixd to the cross-member,the bearing and the flexible material each being fixed to the support,the bearing further comprising a plane rib extending in a plane perpendicular to a horizontal transverse direction of the aircraft,wherein the flexible material is a first material, the bearing includes at least one insert made of a second material interposed between two layers of the first material, the second material being more rigid than the first material.
