Inflatable pads with adjustable static hold downs

1. A mattress overlay being an inflatable body support formed from a pair of plastic sheets joined together to form a non-inflatable periphery, and the non-inflatable periphery defines an air pressurizable chamber therebetween, thereby providing an air cushion for supporting a person positioned thereatop that dissipates at least pressure to decrease the onset of pressure sores and ulcers, the periphery has a distal end, a proximal end, a first side and a second side, the improvement which comprises:

a first non-inflatable corner strap system that extends from at least one end of the periphery;

a center section, at least two side sections positioned on opposite sides of the center section, and a hold down section having at least two elbow-shaped slits or perforations positioned between the center section and each side section to form the first non-inflatable corner strap system;

each elbow-shaped perforation and slit defines a hold down;

each hold down on each side of the center section is a distinct distance from the center section;

the hold downs are used to secure the mattress overlay onto various sized and styles of mattresses.

2. The mattress overlay of claim 1 wherein a second non-inflatable corner strap system is positioned on the other end of the mattress overlay.

3. The mattress overlay of claim 1 wherein at least one of the slits or perforations are parallel to at least the perimeter of the hold down section.

4. The mattress overlay of claim 1 wherein the center section has a button.

5. The mattress overlay of claim 4 wherein at least one hold down on each side of the center section has at least one slit or other attachment mechanism to connect with the button.

6. The mattress overlay of claim 1 wherein the perimeter of the corner strap system makes the mattress overlay appear to be rectangular.

7. A mattress overlay being an inflatable body support formed from a pair of plastic sheets joined together to form a non-inflatable periphery, and the non-inflatable periphery defines an air pressurizable chamber therebetween, thereby providing an air cushion for supporting a person positioned thereatop that dissipates at least pressure to decrease the onset of pressure sores and ulcers, the periphery has a distal end, a proximal end, a first side and a second side, the improvement which comprises:

a first non-inflatable corner strap system that extends from at least one end of the periphery;

a center section having an attachment device, at least two side sections positioned on opposite sides of the center section, and a hold down section having at least two elbow-shaped slits or perforations positioned between the center section and each side section to form the first non-inflatable corner strap system;

each elbow-shaped perforation and slit defines a hold down;

each hold down on each side of the center section is a distinct distance from the center section and has a catch apparatus to secure to the attachment device;

the hold downs are used to secure the mattress overlay onto various sized and styles of mattresses.

8. The mattress overlay of claim 7 wherein a second non-inflatable corner strap system is positioned on the other end of the mattress overlay.

9. The mattress overlay of claim 7 wherein at least one of the slits or perforations are parallel to at least the perimeter of the hold down section.

10. The mattress overlay of claim 7 wherein the attachment device is a button, a stud, snap button, or one portion of a hook and loop unit.
