Vibrational support surface
View Patent ↗A vibration and modulation system is provided for an array of air cells. The vibration and modulation system includes an air source, a high-pressure reservoir in fluid communication with the air source, and at least one valve coupled between the high-pressure air source and the array of air cells. A control assembly is coupled with the at least one valve and selectively controls a position of the valve to effect a vibratory action in the array of air cells.
1. A vibration and modulation system for an array of air cells, the vibration and modulation system comprising:
an air source;
a high-pressure reservoir in fluid communication with the air source;
at least one valve coupled between the high-pressure air source and the array of air cells; and
a control assembly coupled with the at least one valve and selectively controlling a position of the valve to effect a vibratory action in the array of air cells, wherein the control assembly comprises a pilot valve coupled with the at least one valve, the pilot valve enabling high pressure fluid from the high-pressure reservoir to control a position of the at least one valve.
2. A vibration and modulation system for an array of air cells, the vibration and modulation system comprising:
an air source;
a high-pressure reservoir in fluid communication with the air source;
at least one valve coupled between the high-pressure air source and the array of air cells;
a control assembly coupled with the at least one valve and selectively controlling a position of the valve to effect a vibratory action in the array of air cells; and
evacuation structure coupled with the air cell array, the evacuation structure enabling quick deflation of the air cell array, wherein the evacuation structure comprises a vent on the at least one valve, and wherein the evacuation structure further comprises a vacuum source coupled with the vent.
3. A support surface comprising:
an array of air cells; and
a vibration and modulation system coupled with the air cell array, the vibration and modulation system effecting vibratory action on the air cell array and including:
an air source,
a high-pressure reservoir in fluid communication with the air source,
at least one valve coupled between the high-pressure air source and the array of air cells, and
a control assembly coupled with the at least one valve and selectively controlling a position of the valve to effect a vibratory action in the array of air cells,
wherein each of the air cells comprises an air cell node including a foam insert disposed in an air sealable container.
4. A support surface according to claim 3 , wherein when deflated, the air cells are substantially flat.
5. A vibration and modulation system for an array of air cells for use with a support surface, the vibration and modulation system comprising:
an air source;
a high-pressure reservoir in fluid communication with the air source;
a multi-position valve coupled between the high-pressure air source and the array of air cells, wherein in a first position, the valve permits air to flow from the high-pressure reservoir to the air cells, and wherein in a second position, the valve evacuates air from the air cells to atmosphere; and
a control assembly coupled with the valve, the control assembly comprising means for selectively controlling a position of the valve to effect a vibratory action in the array of air cells.
