Abstract: An apparatus (10) for supporting a patient during a medical procedure includes a bead bag (18) that is filled with compressible beads (20) and that forms a lower layer of the apparatus (10). The apparatus (10) also includes a layer of foam material (30) that is located above the bead bag and an air cell grid (36) that has a plurality of inflatable air cells (38). The air cell grid (36) forms an upper layer of the apparatus (10) and provides a soft surface upon which the patient lies. The bead bag (18), when subjected to a vacuum, becomes rigid for supporting the air cell grid (36) against the patient for helping to maximize a surface area of contact between the patient and the apparatus (10).

Abstract: The invention is an apparatus for securing a mobility aid to the interior of a motor vehicle, such as a bus. The invention includes one or more retractors typically positioned forward of the mobility aid, and one or more retractors typically positioned behind the mobility aid. Some or all of the retractors are provided with a powered tension apparatus for providing opposed tension to the front and rear of the mobility aid, securing it from movement in the vehicle. The tensioning system is capable of being remotely controlled, enabling the securement and release of the mobility aid to be performed easily by either the mobility aid occupant or an operator in the motor vehicle.

Abstract: A system is provided for generating prescription wheelchair seats or specialized seating or body supports. The system includes a deformable seat portion which is formed to specialized dimensions of a seated patient. A planar, linear, array of linear transducers is stepped across the form in one dimension forming a series of signals representative of generally planar cross sections of the form. This series of cross-sectional signals is provided as an input to a numerically controlled cutting device which cuts a series of sheet stock foam in accordance with each cross-sectional area measured. These cross-sectional pieces are then assembled into the prescription seat.

Abstract: A system for generating a prescription wheelchair or other seating or body support arrangement includes a deformable seat portion. A patient to be fitted with the wheelchair is placed upon the seat deforming a surface thereof. A signal representative of force distribution resultant from the patient along the seat is generated. In accordance with this signal, the seat surface may be selectively varied by a plurality of pneumatic actuators. An updated force distribution signal is generated. In this fashion, a means and method is provided for arriving at preselected force distribution of the patient on the wheelchair seat. This data is made available for transmission to a fabrication unit from which a permanent seat cushion with the desired characteristics may be fabricated.
