This invention is a device for translatably positioning a patient along a bed. The device has a motor connected to a series of pulleys. A corresponding series of straps are attached at one end to a respective pulley and at the other end to a bed sheet. As the pulleys are rotated by operation of the motor, each strap is wound around its respective pulley thereby causing the associated sheet to be drawn in the general direction of the pulleys. The device may be operated by the patient or a caregiver and the device contains a safety mechanism that prevents the pulleys from pulling the associated bed sheet completely into the device. In one embodiment of the invention, the components of the device are received onto a portable, adjustable frame that permits the device to be transported to a number of different beds and used with beds of differing sizes.
