Abstract
A thermal therapeutic seating apparatus comprises a seating structure having a first air chamber and a headrest structure having a second air chamber. A heater is operatively associated with the seating structure to heat ambient air in the first air chamber. A heat distribution structure connects the second air chamber to the first air chamber to distribute heated air by natural connection whereby heated air flows from the first air chamber to the second air chamber and back to the first air chamber. This causes the seating element and the headrest element to be heated.
Claims8
A thermal therapeutic seating apparatus comprising:
- (a) a seating structure having a first air chamber,
- (b) a headrest structure having a second air chamber,
- (c) heater means operatively associated with said seating structure to heat ambient air in said first chamber,
- (d) heat distribution means to connect said second air chamber to said first air chamber and to distribute heated ambient air by natural convection whereby heated air flows from said first air chamber to said second air chamber and back to said first air chamber causing said seating structure and said headrest structure to be heated, further characterized in that said heat distribution means includes two separately disposed hollow tubes supporting said headrest structure above said seating structure and being disposed at opposite ends of the seating structure, and in fluid communication with said first and second air chambers, further characterized in that said heat distribution means includes baffle means disposed in said first air chamber and extending between said two hollow tubes for directing the flow of heated air from said first air chamber selectively through one of said tubes to said second air chamber, and for selectively heating one portion of said seating surface adjacent one of said tubes, whereby said baffle means permits selective heated air movement to specific portions of the apparatus for therapeutic heating of parts of the body.
