Abstract
A cell structure for a mattress or support where parallel cells are connected together substantially at their middle plane in series so that at least 5 tubes are sealed together in the series. In certain embodiments, feed cells are provided transverse the cell structure and the feed cells are sealed to the cell structure and include punches to allow fluid pressure form the feed cells to introduce into the cell structure. A rail cell is provide outwards of the feed cells and in certain aspects, the rail cell and alternating ones or groupings of the cells in the cell structure are provided with different pressure sources.
Claims22
A port system for a mattress having first and second sets of cells and a seal in contact with at least a first portion of the first set of cells and at least a second portion of the second set of cells, the system comprising:
- a main body comprising a first port and a second port;
- a sealing surface fluidly isolating the first port from the second port;
- a connector for coupling the first and second ports to a fluid delivery system;
- wherein the first port is configured to deliver fluid under a first oscillating pressure to the first set of cells and the second port is configured to deliver fluid under a second oscillating pressure to the second set of cells, wherein the first oscillating pressure is out of phase with the second oscillating pressure, wherein the first and second ports are configured to deliver the first and second oscillating pressures to the first and second sets of cells such that the seal maintains the first portion of the first set of cells in contact with the second portion of the second set of cells as the first oscillating pressure is delivered to the first set of cells and as the second oscillating pressure is delivered to the second set of cells.
A mattress comprising:
- first and second sets of cells;
- a first feed tube fluidly coupled to the first set of cells;
- a second feed tube fluidly coupled to the second set of cells;
- a first port for delivering fluid under a first oscillating pressure to the first feed tube;
- a second port for delivering fluid under a second oscillating pressure to the first feed tube, wherein the first oscillating pressure is out of phase with the second oscillating pressure;
- a first seal in contact with at least a first portion of the first set of cells and at least a second portion of the second set of cells, wherein the first seal maintains the first portion of the first set of cells in contact with the second portion of the second set of cells when the first and second oscillating pressures are delivered to the first and second feed tubes;
- and
- a second seal fluidly isolating the first feed tube from the second feed tube.
