ABSTRACT:
An adjustable bed that enables a Gatch mechanism to be operated in an excellent fashion to match the flexing of a care recipient's body, and that is, moreover, useable as a superior low platform bed for care recipients. To this end, a parallel link mechanism having a pair of perpendicular arms is provided in the adjustable bed as part of a sitting-up mechanism, and by always keeping these arms in a perpendicular position, the sitting-up mechanism is operated with a position removed from the surface of a lower-back board by a prescribed interval as an imaginary rotation center when the bed is driven. This prevents any slippage of the care recipient's body in relation to the platform surface, thereby suppressing the occurrence of bedsores and realizing a natural sitting-up action that takes account of the care recipient's body movement.
