<P>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. <P>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. <P>COPYRIGHT: (C)2013,JPO&INPIT |
