摘要： A bed apparatus including, at least, two drivers or a first driver and a second driver, the first driver being in linkage with the second driver, comprises: a calculating means for calculating a calculated bed state value, based on the first driver and the second driver; an error detecting means for detecting error between the calculated bed state value and a designated bed state value designated by the user; and, an error correcting means for correcting the detected error when an error is detected by the error detecting means. As a result, it is possible to provide a bed apparatus that can coincide the designated state of the bed apparatus with the actual state of the bed apparatus by appropriately correcting the error between the drivers.

摘要： To provide a bed apparatus that permits the bed to be tilted only when the knee bottom in the bed apparatus is raised so as to be able to positively prevent the user from slipping to the foot side when the bed is tilted. The bed apparatus includes: a tilting driver that can perform a tilting operation of the upper frame so as to create difference in height between the head side and the foot side and, at least, lower the foot side; and an operational state detector that detects that a knee bottom actuation assembly for raising and lowering the knee bottom is operable. The tilting driver performs the tilting operation when the knee bottom forms an angle of 0 degrees or greater relative to the ground and when the operational state detector has detected that the knee bottom actuation assembly is operable.

摘要： In the present invention, in accordance with a tilt and back-raising command (Step S1—Yes), knee-raising operation for raising the knees of the user is performed by actuating a knee bottom placed on a top frame (Step S2). Next, after execution of the knee-raising operation, tilting operation for making the head-side height of the top frame higher than the foot-side height of the top frame by moving up and down the head side and foot side of the top frame relative to the floor (Step S3). By this, the user can take a comfortable position just like sitting in the final position after the user's back has been raised, and it is possible to reduce user's feeling of being pressed on the back and in the belly and prevent user's significant body slippage.

摘要： To provide a bottom for a bed apparatus that can make the user feel comfortable when lying on the bed apparatus. The bottom for a bed apparatus, which is height adjustable and is mounted on the top of a bed apparatus, comprising a plurality of parts each formed of a resin plate having a thickness, including a back bottom, a hip bottom, a knee bottom and a foot bottom. Of the parts, essential parts are joined by connecting parts, and the connecting parts are formed of the same material with, to be thinner than, and integrally with, the essential parts, and, depressed portions are formed on the top surface of the bottom around the center in the width direction of the bottom, and a plurality of passage holes are perforated in the depressed portions from the top surface to the undersurface of the bottom.

摘要： To provide a bottom for a bed apparatus that can relieve the sensation of being pressed and that at the same time is lightweight, easy to transport and can be cleaned easily. A bottom for a bed apparatus having a back-raising mechanism, includes a flexing bottom that is arranged between a back bottom and a hip bottom and can be flexed. In a back-raising operation, the flexing bottom flexes between the back bottom and the hip bottom while sliding downward over the surface of the uprising back bottom.
