Apparatus For Supporting a Person and Method of Forming Thereof
Abstract:
An apparatus having a fabric and method of forming thereof. The fabric's load bearing surface for supporting a load, comprising: at least one layer(s) (Ln) wherein n=0, −1, −2, . . . −i, wherein n=0 represents the at least one layer(s) (Ln) of the load bearing surface that contacts the load. An n=−1, −2, . . . −i, represents successive underlying at least one layer(s) (Ln) of the load bearing surface. An n=−i, represents a bottom underlying at least one layer(s) (Ln). The fabric consists essentially of a polyurethane fiber and a fiber that is chemically different from the polyurethane fiber, and wherein the fabric has been stretched to the point just before encountering the Young's Modulus. The method comprising: cutting the fabric to a predetermined pattern; and stretching the fabric to the point just before encountering the Young's Modulus.
