PROBLEM TO BE SOLVED: To provide a cervical orthosis which allows a wearer to take a supine posture with the occiput saved from pain, and simultaneously to take a stabilized head posture and thereby to treat diseases in the cervical vertebrae.SOLUTION: The cervical orthosis includes a body supporting member having an occiput supporting part, and a plurality of strap members for fixing the body supporting member to a body. An occiput receiving member is fixed around a temporal part in the inside of the occiput supporting part so as to have a predetermined interval with the curved surface of the occiput supporting part. This allows the occiput supporting member to be transformed to the shape of the occiput during the wearers supine posture, thereby dispersing the pressure.COPYRIGHT: (C)2013,JPO&INPIT【課題】、仰臥姿勢においても後頭部に痛み発生を回避できるようにしながら頭部姿勢を安定させ、頚椎疾患の治療を行うことができるようにすること。【解決手段】後頭部支持部分を有する本体支持部材と、該本体支持部材を身体に固定する複数のベルト状部材から成り、後頭部受け部材が、前記後頭部支持部分の湾曲面と所定の間隔をもって、前記後頭支持部材の内側、側頭部近傍位置にて固定され、これにより、仰臥時に後頭部受け部材が後頭部の形状に変形することで圧力の分散を行う。【選択図】図9
