    摘要: A lateral rotation apparatus includes a first adjustable frame positioned under a head segment of a person support surface and operable to rotate the head segment of the person support surface to a head tilt angle in the range of about 7 to about 30 degrees relative to a horizontal support plane. A second adjustable frame is positioned under a torso segment of a person support surface and operable to rotate the torso segment of the person support surface to a torso tilt angle that is within a range of about 5 degrees to about 10 degrees less than the head tilt angle. Each of the first adjustable frame and the second adjustable frame includes an upper frame positioned below the person support surface, and a lower frame coupled to and positioned below the upper frame. The upper frame being moveable with respect to the lower frame.

    摘要: A lateral rotation apparatus may include a person support surface having a head segment and a torso segment. An adjustable leg may have a head support positioned below the head segment. The adjustable leg may have a torso support positioned below the torso segment. The head support may be adjustable to rotate the head segment. The torso support may be adjustable to rotate the torso segment. A linkage assembly may be coupled to the head support and the torso support. The linkage assembly may have a sliding link that is movable between an open position and a closed position. The sliding link may also be rotatable between a first rotational position and a second rotational position. An actuator is operable to move the sliding link.
