The snow groomer track of claim 1, wherein the elastically deformable connectors include a plurality of strips of resilient material, each interposed between a respective grouser and a respective connecting portion of the chain. 4. The snow groomer track of claim 1, wherein the chain includes a plurality of links, and a plurality of hinge connectors configured to hinge connect pairs of adjacent links about a respective hinge axes crosswise to the traveling direction of the snow groomer track, said hinge connectors are elastically deformable to permit controlled relative rotation of any two adjacent links about a plurality of axes not coincident with the respective hinge axis of said two adjacent links. 5. The snow groomer track of claim 4, wherein each of the hinge connectors includes a connecting pin between pairs of adjacent links in the chain and a hinge bush of resilient material inserted between each link in the chain and the connecting pin. 6. The snow groomer track of claim 5, wherein each link includes at least a first and second hinge hole at opposite ends in the traveling direction of the snow groomer track, and each link has a first end connected to a first adjacent link by a first connecting pin inserted inside the first hinge hole, and a second end opposite the first end and connected to a second adjacent link by a second connecting pin inserted inside the second hinge hole. 7. The snow groomer track of claim 6, wherein the first hinge holes and the second hinge holes of each link house respective hinge bushes. 8. The snow groomer track of claim 4, wherein each link is connected to a respective grouser, and has a seat conformal in shape to the blunt edges of the grousers. 9. The snow groomer track of claim 1, wherein each grouser includes: a support bar defining the blunt edge of the grouser and fixed to the chain crosswise to the traveling direction of the snow groomer track; anda blade fitted to the support bar on the opposite side to the blunt edge and defining the grip portion of the grouser. 10. The snow groomer track of claim 1, which includes at least one flexible belt connecting the grousers to one another. 11. A snow groomer comprising: a snow groomer track including: a plurality of spaced apart grousers extending crosswise to a traveling direction of the snow groomer track, each grouser having a grip portion configured to grip a terrain, and a blunt edge opposite the grip portion;a chain connected to the blunt edges of the grousers, said chain configured to be engaged, in use, by a drive sprocket of a snow groomer; anda plurality of elastically deformable connectors configured to connect the chain to the grousers to permit controlled relative rotation of the grousers with respect to the chain in a plane crosswise to the traveling direction of the snow groomer track. 12. The snow groomer of claim 11, including at least one drive sprocket engaging the chain of said snow groomer track. 13. A snow groomer track comprising: a plurality of spaced apart grousers having a plurality of respective longitudinal cavities and extending crosswise to a traveling direction of the snow groomer track, each grouser having: a grip portion configured to grip a terrain, anda blunt edge opposite the grip portion;a chain connected to the blunt edges of the grousers, said chain configured to be engaged, in use, by a drive sprocket of a snow groomer; anda plurality of elastically deformable connectors configured to connect the chain to the grousers to permit controlled relative rotation of the grousers with respect to the chain in a plane crosswise to the traveling direction of the snow groomer track, wherein the elastically deformable connectors include: a plurality of threaded pins projecting from the blunt edges of respective grousers and inserted through a plurality of respective fastening holes in the chain, the threaded pins of each grouser being carried by a respective strip housed inside the longitudinal cavity of the grouser, and being inserted through at least one opening formed in the blunt edge of the grouser,a plurality of nuts fitted to respective threaded pins, anda plurality of first bushes of resilient material, housed in the fastening holes, about the respective threaded pins. 14. A snow groomer track comprising: a plurality of spaced apart grousers extending crosswise to a traveling direction of the snow groomer track, each grouser having: a grip portion configured to grip a terrain, anda blunt edge opposite the grip portion; anda chain connected to the blunt edges of the grousers, said chain including a plurality of links, and a plurality of hinge connectors configured to hinge connect pairs of adjacent links about a respective hinge axes crosswise to the traveling direction of the snow groomer track, said hinge connectors are elastically deformable to permit controlled relative rotation of any two adjacent links about a plurality of axes not coincident with the respective hinge axis of said two adjacent links and each of the hinge connectors including a connecting pin between pairs of adjacent links in the chain and a hinge bush of resilient material inserted between each link in the chain and the connecting pin, said chain configured to be engaged, in use, by a drive sprocket of a snow groomer. 15. The snow groomer track of claim 14, wherein each link includes at least a first and second hinge hole at opposite ends in the traveling direction of the snow groomer track, and each link has a first end connected to a first adjacent link by a first connecting pin inserted inside the first hinge hole, and a second end opposite the first end and connected to a second adjacent link by a second connecting pin inserted inside the second hinge hole. 16.
