First Claim
1. A patient positioning device for attaching to a hospital bed of the type including a stationary bed frame, a movable bed frame joined to said stationary bed frame, a mattress supported by said movable bed frame and side rails for preventing a patient from rolling onto the floor, comprising:
- (a) patient corset means for wrapping around the torso of a patient;
(b) at least one elongated flexible strap means, having first and second ends, opposably coupled to said patient corset at locations corresponding to the patient'"'"'s sides;
(c) drive means disposed beneath said bed frame and coupled to said strap means for applying a pulling force to effect movement of said corset means; and
(d) control means attached to said drive means for regulating the movement of said strap means.

Abstract
A patient positioning device for manipulating mobility impaired patients is disclosed. A specially dimensioned corset adapted to be positioned around the torso of the patient is coupled to a flexible strap which is routed via bed frame mounted guides to a drive assembly located beneath the bed'"'"'s mattress. The flexible strap is of a length sufficient to permit it to extend from the corset and over the a conventional hospital bed protective side rails to the drive assembly.
A variety of motors and drive systems are disclosed. One alternative features a reversible motor connected to a double roller mechanism. The strap is wound on a separate one of the rollers, so as the drive shaft rotates in one direction, one roller winds the strap upon itself while the other roller plays out a section of strap. Alternatively, a traveling block to which the strap is coupled pulls on one strap end while it feeds out the other.
