The invention claimed is: 1. An inter-vane platform for a support disk for vanes of a fan of a turbine engine, said inter-vane platform comprising a central part configured to be of one piece with said support disk between two adjacent vanes and two lateral parts forming extensions to two lateral edges of said central part, and each lateral part configured to deflect under the impact of the vane opposite which said lateral part is located, and wherein at least said lateral parts are made of a shape-memory material. 2. The platform according to claim 1, wherein said lateral parts and said central part are a single block. 3. The platform according to claim 1, wherein said lateral parts are fixed with said central part by way of a fixation device. 4. The platform according to claim 1, wherein said platform is made from a metallic material. 5. A vane support disk, comprising a plurality of inter-vane platforms according to claim 1, interlaced respectively between the pairs of adjacent vanes. 6. An inter-vane platform for a support disk for vanes of a fan of a turbine engine, said inter-vane platform comprising a central part configured to be of one piece with said support disk between two adjacent vanes and two lateral parts forming extensions to two lateral edges of said central part, and each lateral part configured to deflect under the impact of the vane opposite which said lateral part is located, wherein said central part presents a first thickness, and said lateral parts present a second thickness less than said first thickness, and at least said lateral parts are made of a shape-memory material. 7. The platform according to claim 6, wherein said central part presents a first resistance to deformation, and said lateral parts present a second resistance to deformation less than said first resistance. 8. The platform according to claim 6, wherein said lateral parts and said central part are a single block. 9. The platform according to claim 6, wherein said platform is made from a metallic material. 10. A vane support disk, comprising a plurality of inter-vane platforms according to claim 6, interlaced respectively between the pairs of adjacent vanes. 11. An inter-vane platform for a support disk for vanes of a fan of a turbine engine, said inter-vane platform comprising a central part configured to be of one piece with said support disk between two adjacent vanes and two lateral parts forming extensions to two lateral edges of said central part, and each lateral part configured to deflect under the impact of the vane opposite which said lateral part is located, wherein said central part presents a first resistance to deformation, and said lateral parts present a second resistance to deformation less than said first resistance, and at least said lateral parts are made of a shape-memory material. 12. The platform according to claim 11, wherein said lateral parts and said central part are a single block. 13. The platform according to claim 11, wherein said platform is made from a metallic material. 14. A vane support disk, comprising a plurality of inter-vane platforms according to claim 11, interlaced respectively between the pairs of adjacent vanes. 15. A turbomachine comprising the inter-vane platform according to claim 1.
