ABSTRACT:

FIELD OF THE INVENTION
This invention relates to mask-like support members suited for use with braces, and more particularly to appliances to support or fasten bodily parts and support members formed of plastics reinforced with triaxial woven fabrics suited for use with artificial limbs and other such appliances. Background of the Invention
Brace support members are used with supporters, braces, rehabilitation appliances and artificial limbs that are intended to reduce loads acting on bones, joints and muscles or fasten them in position by supporting or fastening limbs or the trunk of the human body. Brace support members are generally made by combining foamed resin sheets, cloth or other similar materials so as to keep out of direct contact with skins and provide better fitting with the shape and motion of bodies.
Conventional brace support members have mostly been made by forming such thermoplastic plastics as polyethylene, polypropylene, polycarbonate and nylon.
Because brace support members are required to have high rigidity and durability, those made of plastics with low strengths and low moduli of elasticity are used by imparting the required rigidity and durability by increasing thickness.
Increasing the thickness to provide the necessary rigidity and durability to the braces made of conventional used plastics results in increased weight. In addition, plastics tend to cause sweating, stuffiness, unsanitary conditions, itching and other unwelcome problems because they do not breathe. Provision of openings to permit ventilation entails lowering of rigidity and durability which, in turn, necessitates further increase of thickness to insured the required rigidity and durability. Reinforced plastic unidirectional or biaxial woven fabrics are lighter and more rigid than unreinforced ones. Even so, such reinforced plastic fabrics also undergo unavoidable lowering of rigidity and durability when ventilating openings are provided. Summary of the Invention
The object of this invention is to provide holding and supporting appliances used in the fields of orthopedics, rehabilitation and sports and support members thereof that are light in weight, thin, rigid and durable and permeability well, and, furthermore, to provide support members made of reinforced plastic triaxial woven fabrics impregnated with resin.
To achieve the above object, the support members according to this invention comprises a mask-like piece formed of reinforced plastic triaxial woven fabrics.
Preferably, the formed piece should have openings representing 5 to 33 percent of the overall area thereof, and a flexural rigidity of 10 to 1×10
