[Means for Solving the Problem]

[0006] The present invention that solves the aforementioned problem relates to a support tool for bed and seat, comprising: a main body frame member having a bottom face part, a back face part and both side face parts; a mattress which is housed in the main body frame member, and is divided into a seat face part and a backrest part; a main belt which is detachably attached after having been passed to an outer circumference of the seat face part or the backrest part of the mattress; and a crotch belt which is detachably attached to the main belt, wherein, when the support tool is employed for a bed, the mattress is stretched so that the seat face part and the backrest part of the mattress is made flat in shape, a part of which is employed to be placed on the bottom face part of the main body frame member, and when the support tool is used for a seat, the backrest part of the mattress is abutted against the back face part of the main body frame member and the seat face part of the mattress is placed on the bottom face part of the main body frame member, or alternatively, the mattress is folded to thereby ensure that the seat face part and the backrest part of the mattress are overlapped on each other so that the seat face and backrest parts are employed to be placed on the bottom face part of the main body frame member.

[0007] The support tool for bed and seat, according to the present invention (hereinafter, simply referred to as the support tool of the present invention), comprises a main body mattress member, a mattress, a main belt, and a crotch belt. The main body frame member generally comprises a frame, a cushion member which is wound around the frame, and a covering member to cover these frame and cushion member, and as a whole, has a bottom face part, a back face part, and both side face parts, and further, a front face part and a top face part each are formed in an opened shape thereof.

[0008] The mattress comprises a cushion member, for example, a planar shape made of a polyester compression cotton, and a covering member to cover the cushion member, and as a whole, is divided into a seat face part and a backrest part. The mattress, when it is folded to thereby ensure that the seat face part and the backrest part are overlapped on each other, is housed in an internal space which is surrounded by the bottom face part, the back face part, and both side face parts of the main body frame member, and when the support tool is employed for bed, the mattress is stretched so that the seat face part and the backrest of the mattress are made flat in shape, a part of which is employed to be placed on the bottom face part of the main body frame member, and further, when the support tool is employed for a seat, the backrest part of the mattress is abutted against the back face part of the main body frame member and the seat face part of the mattress is placed on the bottom face part of the main body frame member or the mattress is folded to thereby ensure that the seat face part and the backrest part of the mattress are overlapped on each other so that the seat face and backrest parts are employed to be placed on the bottom face part of the main body frame member.

[0009] The main belt, at one end part or both end parts thereof, comprises an engagingly locking means, for example, a pair of Velcro tapes and a pair of a key piece and a lock piece or the like so as to be detachably attached after having been passed to the outer circumference of the seat face part or the backrest part of the mattress. It is preferable that the main belt, when the main body frame member has been placed on the seat, has an equivalent length so as to be able to be detachably attached after having been passed to the outer circumference of the backrest part of the seat as well.

[0010] The crotch belt is intended to detachably attached to the main belt. Although the shape of the crotch belt may be any shape, it is preferable that the shape is a substantial T-shape or a substantial Y-shape in an unfasten state, so that, in this case, both upper pieces and a lower piece, each of which formed in the substantial T-shape or substantial Y-shape, can be detachably attached. For example, ring parts are provided at two portions of the main belt, one upper piece of the crotch belt that has been formed in the substantial T-shape or substantial Y-shape, is passed through one of these ring parts, whereas the other upper piece is passed through the other ring part, and further, both of the upper pieces that have been passed therethrough are folded on each other, both upper pieces are fastened with buttons, and an end part of the lower piece of the crotch belt is fastened with a Velcro tape.
