Movable bed

The An adjustable bed comprising:

• a plurality of airbags laid along a bed surface;
• a sidewall lift mechanism adapted to inflate airbags provided on side parts of the bed surface, to form a pair of sidewalls;
• a flex mechanism adapted to form a flexion position that includes at least one of a sitting-up position and a knee break, by inflating or deflating an airbag provided on a middle part of the bed surface;
• and
• a tilt mechanism adapted to inflate or deflate airbags provided on the middle and side parts after the sidewall lift mechanism is operated, so as to tilt the bed surface of the middle part toward one of the sidewalls, wherein
• the flex and tilt mechanisms are both operable with the other mechanism in an operational state.

The A sequence for adjusting an adjustable bed that includes a platform having a flexible surface, a flex mechanism adapted to flex the platform to form a flexion position which includes at least one of a sitting-up position and a knee break, a side member disposed on a side of the platform, a side-member lift mechanism adapted to raise the side member relative to the platform surface, and a tilt mechanism adapted to tilt the platform surface laterally, comprising:

• a first step of operating the flex mechanism;
• a second step of operating the side-member lift mechanism after the first step;
• and
• a third step of operating the tilt mechanism after the second step.

The A sequence for adjusting an adjustable bed that includes a platform having a flexible surface, a flex mechanism adapted to flex the platform to form a flexion position which includes at least one of a sitting-up position and a knee break, a side member disposed on a side of the platform, a side-member lift mechanism adapted to raise the side member relative to the platform surface, and a tilt mechanism adapted to tilt the platform surface laterally, comprising:

• a side-member lift step of raising the side member to a predetermined angle at a drive time of the side-member lift mechanism;
• a tilt step of operating the tilt mechanism after the side-member lift step;
• and
• a release control step of performing a release control after the tilt step, by lowering the side member from the predetermined angle to an obtuse angle.
