Abstract

This parachute comprising a canopy having a leading edge and a trailing edge opposite the leading edge, suspension lines each having a first end attached to the leading edge and a second end that is designed to bear a load, and a slider having through-elements for the suspension lines to pass through, said elements being connected to one another by attachment means, each of said through-elements being passed through by one of the suspension lines and being free to move in translation relative thereto, the slider being designed to slide along the suspension lines that pass through the through-elements in the direction from the first ends of said suspension lines towards their second ends under the effect of gravity and the force generated by the suspension lines spreading apart when the parachute starts a descent, tightening and spreading apart the suspension lines as the canopy inflates.

First claim

The invention claimed is:

1 . A parachute including:
a canopy having a leading edge and a trailing edge opposite the leading edge; suspension lines, each suspension line having a first end attached to the leading edge and a second end that is configured to bear a load; and at least two sliders, each slider having through-elements for the suspension lines to pass through, said through-elements being connected to one another by attachment means, each of said through-elements being passed through by one of the suspension lines and being free to move in translation relative thereto, wherein each of the at least two sliders is configured to slide along the suspension lines that pass through the through-elements in the direction from the first ends of said suspension lines towards their second ends when the parachute starts a descent, tightening and spreading apart the suspension lines as the canopy inflates, wherein: the canopy has sections, the at least two sliders are separate and each slider is formed by a separate strap formed by a strip and such that the strip of one slider of the at least two sliders is disconnected from the strip of the other slider of the at least two sliders, and each slider is configured to slide along the suspension lines that pass through the through-element from the first ends of said suspension lines towards their second ends under the effect of gravity and the force generated by the suspension lines spreading apart when the parachute starts a descent, tightening the suspension lines as the canopy inflates, each slider is free to move in translation relative to each of the suspension lines which pass through its through-elements.

2 . The parachute according to claim 1 , wherein the through-elements are formed by rings and the attachment means have lines each connecting two successive rings.

3 . The parachute according to claim 1 , wherein the attachment means have said straps and the through-elements are formed by eyelets passing through said straps.

4 . The parachute according to claim 1 , wherein the slider is in abutment with the leading edge.

5 . The parachute according to claim 1 , wherein the distance between two through-elements of a same slider is strictly less than that separating the first ends of two suspension lines at the leading edge.

6 . The parachute according to claim 1 , wherein the canopy has sections and the number of sliders corresponds to fifteen to twenty-five percent of the number of sections.

7 . The parachute according to claim 1 , wherein the attachment means are made of rope, strap or fabric.

8 . The parachute according to claim 1 , also having a riser to which the second ends of the suspension lines and the load are connected.

9 . The parachute cluster having a plurality of parachutes according to claim 8 , the respective risers of which are connected to a same load.
