Abstract

The invention relates to the provision of a structure (2) which can be used alone or in conjunction with other components, such as a support frame or the like. The structure is movable to a condition for use, at the time of manufacture or subsequently, in which the interior of a number of cells in the structure are filled with a fluid, most typically by inflation with a gas such as air. The structure includes a plurality of cells (14) which can be filled with air, and at least two of which are interconnected to allow the flow of fluid therebetween during use and particular upon impact on one of cells occurring, so as to mitigate the effect of the impact in a controlled manner.

Claims

1. A fluid filled structure, said structure having a body with a plurality of cells in which a fluid is received and wherein at least two of said cells are interconnected by at least one choke port to allow the passage of fluid between said cells in order to allow the controlled transfer of the fluid between the cells once the structure is filled with the desired quantity of the fluid for use and during use of the structure wherein a first cell is provided with a top wall and a base wall spaced apart by side walls, said side walls attached to, or common with, side walls of one or more adjacent cells such that the said first cell is substantially surrounded by one or more cells and provided in fluid communication with the cell or cells adjacent the side walls thereof via said one or more ports in order to allow the passage of fluid between the respective cells.

5. A structure according to claim 1 wherein there are provided one or a series of cells in successive phases outwardly from said first cell, said phase in interconnected to at least one of the first cell or a further phase adjacent thereto via said ports and the passage area of the port or ports in combination which connect the first cell to the surrounding cell or cells phase and through which fluid can pass is different to the passage area of the port, or ports in combination, which connect the said surrounding cell or cells phase to the next phase of cell or cells.

8. A structure according to claim 1 wherein when the structure is in a dormant state and inflated no, or limited, movement of fluid between cells occurs and movement of fluid occurs upon a sudden impact and/or movement of a person in contact with the apparatus with the movement of the fluid regulated by the at least one port which interconnects the cells.

9. A structure according to claim 1 wherein the at least one port is of a dimension and/or is controlled such as to restrict the passage of air so as to substantially maintain the structure in a desired form and/or maintain the air pressure within a specific cell or cells when the pressure on that cell is increased so as to decrease the speed of change of the structure and/or the size of the cell for at least a period of time following the occurrence of an impact and/or movement with respect to the structure.

10. A structure according to claim 1 wherein the interconnected cells which are closest to a predetermined portion of the structure are interconnected by one or more ports which are of a dimension so as to allow a greater flow of air therethrough in comparison to the port or ports which interconnect other cells of the structure which are further removed from the predetermined portion.

14. A structure according to claim 1 wherein the structure is formed by a plurality of cells which are interconnected and adjacent cells are interconnected by at least one port and arranged in series.

17. A structure according to claim 1 wherein the structure includes at least one pump for the movement of fluid into the structure and one or more regulators to allow the controlled movement of the fluid.

21. A structure according to claim 1 wherein the cells are provided as part of a body which is secured to a relatively rigid support which forms a rear support shell to the structure.

24. A structure according to claim 1 wherein the structure includes an inflatable cell or vent bag which is connected to, but separable from, the structure, said inflatable cell or vent bag acting as a reservoir for a quantity of fluid and connected to allow the transfer of fluid between the inflatable cell or vent bag and at least one of the cells of the structure.

25. A structure according to claim 24 wherein the inflatable cell or vent bag allows a quantity of fluid to be available to be moved between the one or more inflatable cells of the structure and the inflatable cell or vent bag upon impact.

26. A structure according to claim 1 wherein the structure is used to form an impact resistant surface in the form of any or any combination of a wall, floor, deck and/or ceiling of a building or vehicle, or as a layer for the same or for an item of clothing and/or used as, or part of, a seat in any or any combination of vehicles, marine craft, aircraft, military vehicles, use by children with special needs, decks or floors.

30. A structure which is provided as a means of mitigating the effect of an impact or blast on a person in contact with, or in the vicinity of the said structure, and wherein said structure includes a plurality of cells, each of said cells provided to be moved and/or retained in an inflated condition by a gas contained therein and wherein at least two of the said cells are interconnected such that once inflated, the fluid can pass between the said interconnected cells in a regulated and controlled manner wherein the regulation is achieved by the provision of one or more ports or passages which interconnect the said cells so as to allow the passage of gas between the cells but to restrain the flow of transfer of the gas through the ports or passages.

32. A structure according to claim 30 wherein the structure is provided with a first surface onto which a person is able to place part of their anatomy and the opposing surface of the structure is provided to face towards the most likely source of the impact such that the structure is positioned intermediate the person'"'"'s anatomy and the source of impact.

31. (canceled)

33. (canceled)

34. A structure according to claim 34 wherein the structure is incorporated to form the base of a seat, said seat also having a back rest formed of a first rear layer and a second front layer with the majority of said first and second layers being held in a spaced apart configuration.

35. A method of forming structure comprising a number of cells, at least two of which are interconnected by one or more ports to allow the passage of fluid therebetween when the structure is formed, said method comprising the steps of analysing the use to which the structure is to be put, identifying an area or areas of the structure at which impact is most likely to occur, locating a first cell at said area or areas of predicted greatest impact, and wherein substantially enclosing the said first cell to the side walls therefore by locating one or more further cells therewith and providing one or more ports to allow the controlled passage of fluid between the said first cell and the said further cell or cells.

36. A method according to claim 35 wherein the said further cell or cells are provided as a first surrounding phase and then one or more further surrounding phases of cells are provided.
