  • the sections I and I are similarly secured to the upright tubular sections forming the sides of the chair back.
  • reinforcing strip S may extend longitudinally of the tubular sections forming the sides and the top of the back of the chair.
  • An air inlet C in communication with the atmosphere and the inside of the bellows, is mounted in the panel B, and provided with a non-return valve to prevent air from being expelled from the bellows on the compression stroke.
  • the air inlet C should be of liberal size to allow air to enter the bellows freely.
  • the bellows diaphragms preferably are positioned adjacent the outer edges of the panels A and A', inside the tubular back section of the chair and the securing and reinforcing strips F and G.
  • the bellows is shown as comprising a tubular section I8 made of flexible material.

  • Rubber or other rings D1 and E1 are attached to the interior surface of the material of the tubular section I8, in spaced relation to each other, to hold the fabric of the tubular section apart on the expansion stroke of the bellows.
  • Diaphragms F and G are provided, respectively, on opposite sides of the rings, and are secured around their edges to the interior surface of the material of the tubular section I8, as indicated at f' and g', respectively.
  • the diaphragms F and G' are arranged so that they can be caused to approach and recede from the rings D1 and E1 by alternately pressing in and drawing back a pair of webbing or plastic handles f2 and y.
  • the diaphragm F' is provided with a rubber flap valve f3 which is adapted to close an air inlet c when the pressure inside the chair proper is greater than that within the bellows section.
  • a small leak hole lf4 also is provided in the diaphragm F to permit the pressure in the bellows section of the chair and in the remainder of the chair to equalize after the inflation of the chair has been completed.
  • the manipulation of the bellows can be effected by alternately applying and removing manual pressure on the diaphragm through the flexible panels forming the upper section of the chair containing the bellows, or by the use of handle straps 22 of canvas or webbing provided on the outside of the tubes adjacent the diaphragrns F and G. These straps 22 may be provided as alternative or in addition to the handles f2 and g2.
  • a cylindrical extension H of iiexible material is attached to one end of a chair arm M, and terminates in a circular or other wall h1, in which is an air inlet c1.
  • a rubber flap valve J is provided to close the said air inlet when pressure inside the extension H is greater than atmospheric pressure due to the wall h1 being pushed inwardly by the handle h2, which may be of any convenient form.
  • a iiap valve k1 in the inner wall K of the extension H is opened due to such increase of air pressure, and admits air to the interior of the chair arm M through opening c.
  • the valve k1 closes and the valve J opens, re-charging the interior of the extension H.
  • a small leak hole k2 is provided for the purpose already described, also rings or hoops D2 and E2.
