Abstract
Abstract An air cargo barrier net having a front net section releasably attached within an aircraft cargo compartment in restraining contact with the forwardmost cargo load, an integral top net section attached over the upper surface of the cargo load, and connecting lines quick-releasably connected from the front and top net sections to existing cargo tiedown rings installed on the floor of the cargo compartment. The upper surface of the front net section is slidably attached to a pair of horizontal tracks mounted on the ceiling of the cargo compartment and permitting the easy relocation of the net to various positions in the cargo compartment.

Claim 1
Independent Claim
348 words
Barrier net means for resisting movement of cargo loaded in the cargo compartment of an aircraft or other vehicle comprisiNg; a main, vertically-disposed, front barrier net section positioned in contact with, and providing the principal emergency restraint for the cargo in the event of the failure of the normal aircraft cargo restraint system; an auxiliary, top barrier net section integrally joined with opposite top corner extensions of said main, front barrier net section, and disposed in a horizontal relation over and in restraining contact with a substantial portion of the upper surface of, and thereby positively ensuring a significant emergency restraint to the tendency of said cargo to tumble over the top of the said main, front barrier net section in the event of a crash or other emergency resulting in the failure of the normal cargo restraints; fixed barrier netattachment means mounted to the ceiling of the cargo compartment and providing the sole attachment to the aircraft for the top surface and said main front barrier net section; movablypositioned, barrier net-attachment means integrally formed with top corner extensions of said main, front barrier net section and interconnected in slidable relation with said fixed, barrier netattachment means for simultaneously positioning said main, front barrier net section in its vertically-upright and principal cargo load-restraining position, and further providing for, and greatly facilitating its relatively easy and quick adjustment to various cargo load-restraining positions in the cargo compartment; a plurality of fixed and quick-releasable cargo restraint means interconnected between the opposite side and bottom surfaces of said main, front barrier net section and already-existing and periodically-spaced cargo compartment-floor-mounted, fastening means and thereby ensuring the positive hold of the said main, front barrier net section in its vertically-upright, cargo loadrestraining position; and a single pair of fixed and quickreleasable cargo restraint means respectively interconnected one each between other already-installed and regularly-spaced cargo restraints on the aircraft cargo compartment floor and one each with opposite end corners of, and thereby positively retaining said auxiliary, top barrier net section in its horizontallydisposed and cargo-restraining relation over the upper surface of said cargo load.

Claim 3
Dependent Claim
219 words
Barrier net means for resisting movement of cargo as in claim 1, wherein said main, front barrier net section comprises a first plurality of horizontally-disposed webbings or rope sections positioned in spaced-apart and parallel relation to each other; a second plurality of vertically-disposed webbings or rope sections positioned in spaced-apart and parallel relation to each other and further crossing and interconnecting with the horizontally-disposed webbings or rope sections corresponding thereto; and an upper barrier net portion comprising; a single, horizontally-disposed webbing or rope section disposed in spaced relation above the main portion of said front, barrier net section and integrally connected to and in transverse relation with vertical extensions from the left and right side-most vertically-disposed webbings or rope sections; a first pair of relatively short, reinforcing webbings or rope sections extending between and interconnecting opposite ends of and thereby significantly strengthening said single, horizontally-disposed webbing or rope section; said single and reinforced, horizontally-disposed webbing or rope section being further interconnected with and constituting an integral part of said movably-positioned, barrier net-attachment means; and a second pair of relatively long and crossing webbings or rope sections interconnected between opposite top sides of, and thereby strengthening said main, front barrier net section at the uppermost portion thereof immediately below and spaced from said single, horizontally disposed webbing or rope section.
