US 6,454,213 B1 · Parachute with enhanced pocket bands

A. a canopy means adapted to be inflated to provide controlled descent for a load attached thereto, said canopy means including an inner surface defining an inflation chamber means therewithin, said canopy means also including an outer surface, said canopy means further including a lower edge means being circular in shape and extending peripherally therearound, said canopy means further defining a canopy vent at the uppermost location thereon;

B. a plurality of suspension lines each attached to said canopy means and extending downwardly from said lower edge means thereof for attachment selectively to a load therebelow;

C. a plurality of radial lines extending from said canopy vent to said lower edge means spaced apart from one another and attached to said canopy means therealong, each of said radial lines being connected with respect to a suspension line extending downwardly therefrom;

D. a plurality of gores defined on said canopy means between adjacent pairs of said radial lines and said lower edge means;

E. a load attachment means attached to said suspension lines and detachably securable to a load for providing controlled aerial descent thereof;

F. a plurality of pocket bands attached to adjacent pairs of said gores extending across said radial line located therebetween, each of said pocket bands comprising:

(1) a first end means fixedly secured to said outer surface of said canopy means adjacent one of said suspension lines at an acute angle relative thereto;

(2) a second end means fixedly secured to said outer surface of said canopy means adjacent one of said suspension lines at an acute angle relative thereto, said second end means being spatially disposed from said first end means;

(3) a central band section being approximately two inches in width and secured to said first end means and said second end means free from any attachment to said canopy means, said first end means and said central band section and said second end means of each of said pocket bands comprising a single integral member of woven fabric, said central band section extending between said first end means and said second end means across said radial line thereadjacent and oriented angularly with respect thereto, said central band section being movable outwardly away from said canopy means to be oriented at an angle extending downwardly and outwardly relative to said radial line thereadjacent to facilitate defining of an inflation pocket therebetween to receive air moving thereinto during initial inflation of said canopy means, said inflation pocket adapted to be inflated during initial inflation of said canopy means to urge outward movement of said lower edge means of said canopy means to facilitate initial inflation thereof, said central band section being positioned angularly with respect to said radial line thereadjacent in order to increase the surface area of said central band section oriented perpendicularly to the direction of flow of inflating air during initial inflation of said canopy means in order to facilitate defining of said inflation pocket adjacent said lower edge means of said canopy means for more rapidly expanding the canopy means to achieve controlled initial deployment thereof, said central band section of said pocket band including:

(a) an upper band segment extending between said first end means and said second end means;

(b) a lower band segment also extending between said first end means and said second end means, said lower band segment being of greater length than said upper band segment in order to allow said central band section to be oriented angularly with respect to the relative direction of movement of air during initial inflation of said canopy means, said upper band segment and said lower band segment being formed of a single integral member of woven fabric, said central band being of a trapezoidal shape and defining a first parallel side and a second parallel side each being parallel with respect to one another with said second parallel side being longer than said first parallel side, said first parallel side being positioned on said upper band segment and said second parallel side being positioned on said lower band segment to enhance outwardly flaring of said lower band segment relative to said upper band segment to facilitate defining of an inflation pocket during initial inflation adjacent said radial line attached to said canopy means;

G. a first angular stitching for attaching of said first end means to said canopy means at an acute angle relative to said radial lines to facilitate orienting of said central band section angularly relative to the movement of inflating air to urge inflation of said inflation pocket thereadjacent during initial inflation of said canopy means, said first angular stitching includes a first inner stitching seam immediately adjacent said central band section to facilitate orientation thereof angularly relative to said radial lines to increase the lifting force vector thereon resulting from air movement relatively parallel to said suspension lines during initial inflation of said canopy means and prior to full inflation thereof;

and

H. a second angular stitching for attaching of said second end means to said canopy means at an acute angle relative to said radial lines to facilitate orienting of said central band section angularly relative to the movement of inflating air to urge inflation of said inflation pocket thereadjacent during initial inflation of said canopy means, said second angular stitching includes a second inner stitching seam immediately adjacent said central band section to facilitate orientation thereof angularly relative to said radial lines to increase the lifting force vector thereon resulting from air movement relatively parallel to said radial lines during initial inflation of said canopy means and prior to full inflation thereof.
