Figure adjusting pad and process for manufacturing same
First Claim
1. A figure adjusting pad comprisinga silicone gel element having a predetermined shape including an inner portion and an outer peripheral portion about a periphery of said inner portion;
- a stretchable fabric covering said silicone gel element in such a manner that an outermost edge of said outer peripheral portion of said silicone gel element is exposed outwardly from said stretchable fabric;
wherein said silicone gel element has perforations formed therein which comprise traces formed by elution of particles incorporated in a silicone gel stock solution for said silicone gel element;
wherein said inner portion of said silicone gel element varies in thickness depending on location;
wherein said stretchable fabric and said outer peripheral portion of said silicone gel element are double-sewn at a predetermined location inwardly of said outermost edge of said outer peripheral portion in such a manner as to compress a portion of said outer peripheral portion of said silicone gel element and form an expanded portion outwardly of said predetermined location, said expanded portion having a thickness less than that of said inner portion of said silicone gel element; and
wherein said silicone gel element has a penetration of 40 to 60 measured according to JIS K2207-1980 (load;
50 g) and a void volume of 50 to 65% defined by said traces of elution of said particles.

Abstract
A figure adjusting pad is capable of permitting a periphery of the pad to exhibit satisfactory shape retention without any independent core. The pad includes a silicone gel element formed therein with perforations and a stretchable fabric arranged for covering the silicone gel element and is trimmed. The perforations of the silicone gel element are formed by traces defined by elution of particles incorporated in a silicone gel stock solution for the silicone gel element. The trimmed portion includes the silicone gel element and is double-sewn together with the silicone gel element.

6. A process for manufacturing a figure adjusting pad, comprising:
-
a shaping sheet adhering step for adhering a stretchable fabric and a shaping sheet to each other; a mold forming step for forming said shaping sheet into two molds; a pad blank forming step for pouring a silicone gel stock solution having particles incorporated therein into a stretchable fabric side of one of said molds, intimately contacting a stretchable fabric side of the other of said molds with said silicone gel stock solution and curing said silicone gel stock solution into a desired shape in a die while heating and pressurizing it, to thereby form a pad blank including a cured silicone gel element; a peeling step for peeling only said shaping sheet from each of said molds; a perforating step for removing said particles from said silicone gel element by elution to provide said silicone gel element with perforations; a cutting-off step for cutting off an extra peripheral portion of said pad blank therefrom; and a sewing step for double-sewing a cut periphery of said pad blank to form the figure adjusting pad; at least one of said molds being formed with a peripheral overflow passage in said mold forming step; said silicone gel stock solution being poured in said one mold in an amount sufficient to permit said silicone gel stock solution to extend to said peripheral overflow passage and then cured in said peripheral overflow passage as well as in said one mold during said molding forming step; said pad blank being cut off at a portion thereof corresponding to said peripheral overflow. - View Dependent Claims (7, 8, 10, 11, 12, 13, 14)

15. A process for manufacturing a figure adjusting pad, comprising:
-
a shaping sheet adhering step for adhering a stretchable fabric and a shaping sheet to each other; a mold forming step for forming said shaping sheet into two molds; a pad blank forming step for pouring a silicone gel stock solution having particles incorporated therein into a stretchable fabric side of one of said molds and curing said silicone gel stock solution into a desired shape in a die while heating and pressuring it, to thereby form a pad blank including a cured silicone gel element; a mold adhering step for adhering a stretchable fabric side of the other of said molds to an exposed surface of said silicone gel element; a peeling step for peeling only said shaping sheet from each of said molds; a perforating step for removing said particles from said silicone gel element by elution to provide said silicone gel element with perforations; a cutting-off step for cutting off an extra peripheral portion of said pad blank therefrom; and a sewing step for double-sewing a periphery of said pad blank to form the figure adjusting pad; said one mold being formed with a peripheral overflow passage in said mold forming step; said silicone gel stock solution being poured in said one mold in an amount sufficient to permit said silicone gel stock solution to extend to said peripheral overflow passage and then cured in said peripheral overflow passage as well as in said one mold during said mold forming step; said pad blank being cut off at a portion thereof corresponding to said peripheral overflow passage. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A figure adjusting pad comprising;
-
a silicone gel element having a predetermined shape including an inner portion and an outer peripheral portion about a periphery of said inner portion; a stretchable fabric covering said silicone gel element in such a manner that an outermost edge of said outer peripheral portion of said silicone gel element is exposed outwardly from said stretchable fabric; wherein said silicone gel element has perforations formed therein which comprise traces formed by elution of particles incorporated in a silicone gel stock solution for said silicone gel element; wherein said inner portion of said silicone gel element varies in thickness depending on location; wherein said stretchable fabric and said outer peripheral portion of said silicon gel element are double-sewn at a predetermined location inwardly of said outermost edge of said outer peripheral portion in such a manner as to compress a portion of said outer peripheral portion of said silicone gel element and form an expanded portion outwardly of said predetermined location, said expanded portion having a thickness less than that of said inner portion of said silicone gel element; and wherein a trimming fabric element is wrapped about the outermost edge of said outer peripheral portion of said silicone el element and about an outermost edge of said stretchable fabric, said trimming fabric element being double-sewn with said stretchable fabric and said outer peripheral portion of said silicone gel element at said predetermined location. - View Dependent Claims (25, 26)
