Abstract
A low stretch fabric for use in inflatable devices that place pressure on body parts, such as anti-G garments. The novel design of the present invention allows it to inflate to a lesser volume, than conventional fabrics, while maintaining the same pressure. This results in faster response times and less bulk of the garment constructed of the present invention.
Claims32
An inflatable garment comprising a low stretch fabric for placing pressure on a body part, said fabric comprising:
- a plurality of warp yarns;
- a plurality of filling yarns;
- said warp yarns being woven with said filling yarns so as to form a fabric;
- said filling yarns having a diameter and spacing greater than that of said warp yarn, so as to minimize crimp in said filling yarns, said fabric enabling inflation of the garment at a minimized volume while applying the desired pressure to the body part.
An inflatable garment comprising a low stretch fabric for placing pressure on a body part, comprising:
- a plurality of warp yarns;
- a plurality of filling yarns;
- said warp yarns being woven with said filling yarns so as to form a fabric;
- said warp yarns having a diameter and spacing greater than that of said filling yarns so as to minimize crimp in said warp yarns, said fabric enabling inflation of the garment at a minimized volume while applying the desired pressure to the body part.
An inflatable anti-G garment comprising a low-stretch fabric, said low stretch fabric comprising:
- a plurality of warp yarns;
- a plurality of filling yarns;
- said warp yarns being woven with said filling yarns so as to form a fabric;
- said filling yarns having a diameter and spacing greater than that of said warp yarn so as to minimize crimp in said filling yarns, said low stretch fabric enabling inflation of the garment to a minimum volume while applying the force required to counter the effect of G forces.
An inflatable anti-G garment comprising a low-stretch fabric, said low stretch fabric comprising:
- a plurality of warp yarns;
- a plurality of filling yarns;
- said warp yarns being woven with said filling yarns so as to form a fabric;
- said warp yarns having a diameter and spacing greater than that of said filling yarns so as to minimize crimp in said warp yarns, said low stretch fabric enabling inflation of the garment to a minimum volume while applying the force required to counter the effect of G forces.
In a process for forming an inflatable garment from a woven fabric, for the purpose of applying pressure to a body part, the improvement which comprises utilizing, as the woven fabric:
- a low stretch material having an axis of least crimp, comprising a plurality of warp yarns;
- a plurality of filling yarns;
- said warp yarns being woven with said filling yarns so as to form a fabric;
- one of said warp and filling yarns having a diameter and spacing greater than the other of said warp and filling yarns so as to minimize crimp in said one of said warp and filling yarns, said axis of least crimp corresponding to a direction in which said one of said warp and filling yarns extends;
- determining a direction of maximum strain within the material of the garment when assembled and inflated;
- orienting said fabric and forming said garment so that said axis of least crimp is substantially aligned with said determined direction of maximum strain, said low stretch fabric functioning to minimize inflation volume of the garment while providing the required pressure to the body part.
