PROBLEM TO BE SOLVED: To provide a bed device that can incline to the right and left sides sufficiently to allow a person on a bed (on a mattress) to turn over even using a small-sized fan device with a small capacity of air blowing.SOLUTION: The bed device includes: a mattress body 10 on which a person lies and pillar-like (substantially triangle in cross section), flexible fluid bags 24 extending along the longitudinal direction of the mattress body 10 relative to the length direction thereof, and provided under the mattress body 10 on the right and left sides through the center thereof in the width direction. The supply and discharge of air to and from the fluid bags 24 (24L and 24 R) allows the expansion and contraction of the bags.COPYRIGHT: (C)2013,JPO&INPIT【課題】送風量の少ない小型の送風装置であっても、十分にベッド上(マットレス上)の人を左右にローテンションして寝返りを打たせることができるベッド装置を提供する。【解決手段】人が上面に載るマット本体10の下部に該マット本体10の先後方向に長さ方向が沿った柱状(断面略三角形)かつ可撓性の流体袋24をマット本体10の幅方向中心を挟んで左・右に設け、該流体袋24(24L、24R)への空気の供給・排出により膨張・収縮するようになっている。【選択図】図2
