Abstract
(EN)
The present invention relates to a wheelchair having a back plate and a seat plate and a manufacturing method thereof, and more particularly, to a customized wheelchair having a back plate and a seat plate formed to fit a body shape and a manufacturing method thereof. In a method of manufacturing a customized wheelchair having a back plate and a seat plate which are designed to fit a body shape, the method includes steps of: forming a preliminary molding material which is directly formed to fit a back and a hip of a user; fixing the preliminary molding material to a molding frame; filling a foaming resin in the molding frame fixed with the preliminary molding material; hardening the foaming resin filled in the molding frame; and releasing a last molding material which is foamed and hardened to have a shape of the back and the hip of the user by the preliminary molding material. Accordingly, the customized wheelchair, which has the back plate and the seat plate having the exactly same shape as the body shape of the user, can be manufactured by those ordinary skilled in the art in a cost effective manner.

La présente invention concerne une chaise roulante comprenant une plaque de support dorsal et une plaque de support pelvien ainsi qu'un procédé de fabrication de cette chaise, et plus particulièrement une chaise roulante personnalisée comprenant une plaque de support dorsal et une plaque de support pelvien formées de façon à épouser la forme du corps ainsi qu'un procédé de fabrication de cette chaise. Dans un procédé de fabrication d'une chaise roulante personnalisée comprenant une plaque de support dorsal et une plaque de support pelvien conçues pour épouser la forme du corps, le procédé consiste à former une matière de moulage préliminaire, laquelle est directement formée de façon à épouser le dos et le bassin de l'utilisateur, à fixer la matière de moulage préliminaire sur une structure de moulage, à remplir d'une résine moussante la structure de moulage sur laquelle la matière de moulage préliminaire est fixée, à durcir la résine moussante remplissant la structure de moulage, et à libérer au moins la matière de moulage expansée et durcie en vue de l'obtention de la forme du dos et du bassin de l'utilisateur au moyen de la matière de moulage préliminaire. Par conséquent, cette chaise roulante personnalisée comprenant une plaque de support dorsal et une plaque de support pelvien épousant exactement la forme du corps de l'utilisateur peut être fabriquée à moindres frais par les hommes du métier.
