Patent ID: 7992239

Claim:
A patient support apparatus comprising a lower frame; a lift mechanism including a lift drive configured to at least one of expand and contract the lift mechanism, the lift mechanism being pivotably coupled with the lower frame to rotate about a rotational axis; a drive mechanism coupled between at least one of the first lift mechanism and the second lift mechanism and the lower frame, the drive mechanism configured to rotate the lift mechanism about the rotational axis; and an upper frame supported on the lift mechanism and responsive to the rotation of the lift mechanism to rotate a patient about the rotational axis, the upper frame including an upper frame base coupled to the lift mechanism and a deck movably supported on an upper frame base, the upper frame base having a first section configured to support a first section of the deck and a second section configured to support a second section of the deck, the first section of the upper frame base and the second section of the upper frame base being configured to remain substantially co-planar as the first portion of the deck moves with respect to the upper frame base.
