A device supporting a first and a second element of a piece of space equipment. The device includes at least two deployable flexible arms each having a first end and a second end, the ends are secured respectively to the first and second elements and each designed to adopt at least one initial position folded in curves and an unfolded final position, in which positions they hold the first element away from the second element by first and second chosen distances respectively, the second distance being greater than the first.

1. A device for supporting first and second elements of a piece of space equipment, comprising: at least two deployable flexible arms each comprising a first end and a second end in which said first and second ends are secured respectively to the first and second elements and each arm has an initial
1. A device for supporting first and second elements of a piece of space equipment, comprising: at least two deployable flexible arms each comprising a first end and a second end in which said first and second ends are secured respectively to the first and second elements and each arm has an initial position folded in curves and one unfolded final position; in said initial and final positions said arms hold said first element away from said second element by first and second distances respectively, said second distance being greater than said first distance, wherein a first frame is fixed to said first element and said first end of each arm, and a second frame is fixed to said second element and said second end of each arm, wherein said first and second ends of each arm are respectively fixed to said first and second frames by a mechanical connection to block any degree of freedom of movement and/or an immobilizing material to block any degree of freedom of movement. 2. The device according to claim 1, comprising at least three deployable flexible arms, each arm comprising a first end and a second end which are secured respectively to said first and second elements at different positions along said first and second elements, said different positions having the at least three arms hold said first element away from said second element in said initial position and said final position by said first and second distances, respectively. 3. The device according to claim 2, comprising three pairs of arms, wherein in each pair of arms the arms constitute two nonparallel sides of a trapezium once the arms have been positioned in the respective final positions of the two arms. 4. The device according to claim 3, wherein said arms of each pair have identical lengths so the corresponding trapezium is of the isosceles type. 5. The device according to claim 2, comprising three pairs of arms wherein each of the two arms within the pairs constitute two sides of a triangle once they have been positioned in said final positions. 6. The device as according to claim 5, wherein said arms of each pair have identical lengths so the corresponding triangle is of the isosceles type. 7. The device according to claim 2 wherein said first frame to which said first element and said first end of each arm are fixed, are fixed and secured to said first element, and said second frame to which said second element and said second end of each arm are fixed, are fixed and secured to said second element wherein each arm comprises a first sub-arm comprising said first end and a third end and a second sub-arm comprising said second end and a fourth end, and in that the device comprises a third frame inserted between said first and second frames to which the third end of said first sub-arm and the fourth end of said second sub-arm are fixed. 8. The device according to claim 7, wherein said third and fourth ends of said first sub-arm and said second sub-arm are fixed to said third frame by a mechanical connection and/or an immobilizing material intended to block any degree of freedom of movement. 9. The device according to claim 2, comprising damping means configured to damp the movement of said second element as each arm reaches a final position. 10. The device according to claim 2, comprising movement means configured to move said first end or said second end of at least one of said arms so as to control said final position of said first end or said second end of said at least one said arms and the position of said second element with respect to said first element. 11. The device according to claim 2, comprising retractable immobilizing means configured to immobilize said first element or said second element with respect to a rigid structure of said piece of equipment while each arm is still in an initial position. 12. The device according to claim 2, wherein said flexible arm is capable of tolerating at least two bends in one and the same plane while it is in said initial position. 13. The device according to claim 1, comprising damping means configured to damp the movement of said second element as each arm reaches a final position. 14. The device according to claim 1, comprising guide means configured to guide at least some movement of said second element as each arm moves from said initial position towards said final position. 15. The device according to claim 1, comprising movement means configured to move said first end or said second end of at least one of said arms so as to control said final position of said first end or said second end of said at least one of said arms and the position of said second element with respect to said first element. 16. The device according to claim 1, comprising retractable immobilizing means configured to immobilize said first element or said second element with respect to a rigid structure of said piece of equipment while each arm is still in the initial position. 17. The device according to claim 1, wherein each flexible arm is made of carbon fiber. 18. The device according to claim 1, wherein said first element is a primary mirror. 19. The device according to claim 1, wherein said second element is chosen from the group consisting of at least a secondary mirror and a focal plane. 20. The device according to claim 1, wherein each flexible arm is capable of tolerating at least two bends in at least one chosen plane while it is in said initial position. 21. The device according to claim 20, wherein said flexible arm is capable of tolerating at least two bends in one and the same plane while it is in said initial position. 22. The device according to claim 20, wherein said flexible arm is capable of tolerating at least two bends in at least two different planes while it is in said initial position. 23. A piece of space equipment comprising at least one assembly of a first and a second element, wherein the first and second elements are supported by the device according to claim 1. 24. The piece of space equipment according to claim 23, wherein said piece of space equipment is arranged in the form of an observation instrument. 25. The piece of space equipment according to claim 24, wherein said observation instrument comprises at least one telescope.
