Definitions

  • the width and/or midpoint width are preferably from about 50 cm to about 100 cm, more preferably from about 60 cm to about 90 cm.
  • the width and/or midpoint width is preferably from about 100 cm to about 220 cm, preferably from about 120 cm to about 200 cm, more preferably from 160 cm to 200 cm.
  • the chambers may be disposed transverse of the mattress or longitudinally. Preferably the chambers are transverse. This can provide most comfort in the event of a chamber being punctured and may also allow easy creation of a headrest or pillow by folding or rolling of an end of the mattress.
  • Adjacent chambers may be sealed from one another, at least once inflated, to substantially prevent flow of an inflating material between them. This may help to maintain comfort in the event one chamber is punctured, and also aids in ensuring a generally even spread of support for a user's body across the mattress.
  • the structural support chambers are unfilled or unexpanded, so that the enveloping flexible sheet is not held in tension by an internal pressure.
  • the chambers, and hence also the mattress, in this state are flexible, and occupy minimal space. This allows for simple packaging and transportation of the mattress in an uninflated state.
  • the flexible sheets may be made from a variety of materials that can confine materials used to inflate the inflated structural chambers of the mattress, for example gases, in particular air or N2.
  • the flexible material preferably has a basis weight of from 10 to 2,000 gsm, preferably from 15 to 1200 gsm, more preferably 20 to 800 gsm, still more preferably 25 to 600 gsm, and most preferably or 30 to 400 gsm.
  • basis weight refers to a measure of mass per area, in units of grams per square meter (gsm).
  • Gas barrier can be increased a thickening of the flexible material.
  • the cutting element is in substantially fixed relation to the fluid injection nozzle.
  • the cutting element is preferably positioned to the rear of the fluid injection nozzle's outlet in relation to the relative movement of the inflatable mattress and fluid injection nozzle.
  • a fluid injection nozzle within the travel path and positioned for insertion in said manifold, the fluid injection nozzle comprising a fluid outlet port for injection of fluid into the manifold and inflatable chambers and being adapted to position the fluid outlet port adjacent to the inflation ports such that as the conveying mechanism conveys the inflatable mattress along the travel path, the inflation nozzle moves longitudinally within the manifold to inflate the chambers sequentially by the introduction of fluid into their respective inflation ports;
  • FIG. 4B is an enlarged partial view of FIG. 4A;
  • FIG. 2A the inflatable mattress 2 is folded or rolled at a head-end to provide a pillow 8. Flexible joining lines provided between adjacent inflatable chambers 6 aid the rolling or folding of the head-end.
  • a sleeve 10 is provided, wrapped about the pillow 8, holding the pillow 8 in place, and possibly also providing additional tactile comfort.
  • the sleeve 10 may be dimensioned to also function as a wrap for the inflated mattress 2 when rolled for ease of user transport.
  • An exemplary joining mechanism may comprise a pair of sealing members that converge within the travel path to form a sealing zone.
  • sealing members may comprise a pair of counter-rotating belts or wheels.
