Claim:
1. A hybrid elastic cable comprising at least one filament yarn of a first type and at least one filament yarn of a second type, the at least one filament yarn of the first type having a lower degree of tenacity than that of the at least one filament yarn of the second type, and the at least one filament yarn of the second type having a lower degree of elasticity than that of the at least one filament yarn of the first type; the at least one filament yarn of the second type, when a predetermined maximum rate of elongation of the hybrid elastic cable is reached, is fully elongated and the at least one filament yarn of the first type is wound in a helix around the at least one filament yarn of the second type, wherein the at least one filament yarn of the first type with said predetermined maximum rate of elongation is wound in a helix around the at least one filament yarn of the second type with a specific number of turns per linear meter of the hybrid elastic cable ranging between n sE −15% and n sE +15%, n sE being determined based on the following formula: in which n the at least one filament yarn of the first type moreover being also twisted about itself with a specific number of distinct turns about itself per linear meter of the hybrid elastic cable ranging between n in a manner such that when the hybrid elastic cable is at rest, the at least one filament yarn of the second type is wound in a helix around the at least one filament yarn of the first type, without the separation of the at least one filament yarn of the second type from the at least one filament yarn of the first type or deformation of the hybrid elastic cable.
