Interface pads

These interface pads have a right and a left inflatable member with the volume of air in each of these inflatable members being independently adjustable. Each member is adapted to provide an interface between one side of a load-bearing animal and a load-supporting structure such as a saddle. Connecting means span the spinal area of the animal and link the members to one another in a manner that avoids the placement of any substantial compression on the animal's supraspinous ligament. Moreover, a gullet channel is maintained so as to allow appropriate ventilation in this area. The inflatable members are constructed of a foam core wholly surrounded by and bonded to a pair of thin skins or panels, forming a fluid tight envelope. A valve is disposed between the chamber formed by the envelope and the ambient environment. After allowing inflation of an air pad of this type and placing a load (such as the saddle and/or rider) thereon, the valve can be opened. In this situation, the air pad will conform to the contours and configuration of both saddle and animal until it reaches a point where the pressure exerted by foam and air remaining in the foam matches the exterior pressure placed on its various parts. The use of a proportional valve is preferred as this makes the process virtually automatic.
