Abstract
Abstract A relaxation apparatus includes a mattress consisting essentially of an inflatable hollow body defining an interior space and having an upper reclining surface area for carrying a human body. An air pump is connected to the hollow body for inflating it with air. A vibrating device cooperates with the pump for periodically varying the pressure in the interior space at a preselected frequency so as to raise and lower the reclining surface area periodically. The vibrating device includes a control system for varying the preselected frequency within a range containing the breathing rates.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
120 words
A relaxation apparatus comprising: a mattress consisting essentially of an inflatable hollow body defining an interior space and having an upper reclining surface area made of a flexible material for carrying a human body in its entirety; an air pump connected to said hollow body for inflating said hollow body with air and for creating and maintaining a preselected pressure in the interior space of said hollow body; and vibrating means cooperating with said pump for periodically varying with a preselected frequency said pressure in the interior space of said hollow body and for periodically raising and lowering said reclining surface area, said vibrating means including a control system for varying said preselected frequency within a range containing breathing rates.
Claim 2
Dependent Claim
120 words
A relaxation apparatus comprising: a mattress consisting essentially of an inflatable hollow body defining an interior space and having an upper reclining surface area made of a flexible material for carrying a human body in its entirety; an air pump connected to said hollow body for inflating said hollow body with air and for creating and maintaining a preselected pressure in the interior space of said hollow body; and vibrating means cooperating with said pump for periodically varying with a preselected frequency said pressure in the interior space of said hollow body and for periodically raising and lowering said reclining surface area, said vibrating means including a control system for varying said preselected frequency within a range containing breathing rates.
Claim 3
Dependent Claim
22 words
