Definitions

  • My invention relates to pneumatic cushions and like articles which are intended to be sat upon or lain upon or otherwise used to support a human body, for instance, as cushions in conveyances such as automobiles, or mattresses for sleeping cars, and for use under other conditions where it is important to utilize a flexible carrying surface supported by confined air.
  • Objects of my invention are to so construct the cushion that in use it will retain its general shape, but will yield locally to accommodate itself to the person of the user; to avoid objectionable rolling movement, when the load is shifted; to counterbalance resistances in the cushion whereby the carrying surface may yield more readily lengthwise than laterally, while the reverse side will yield less readily lengthwise and more readily laterally, so that the yielding tendencies of .the opposite surfaces of the cushion will offset each other so far as the general configuration of the cushion is concerned; to form such a cushion with transverse, hollow, elevated, integral, undulating rib-like elements on its upper surface, opposed by approximately straight, longitudinally disposed base elements of the cushion, so that the upper surfaces of the cushion can yield, as by stretching out the elevated ribs, with out spreading the cushion substantially lengthwise against the resistance of the straight opposed elements; and to support the various elements of the cushion, prefera bly, by more or less solid, but flexible, weblike portions so as to preserve its forms and to produce a carrying surface which will have suflicient continuity to

  • Fig. 7 is a horizontal sectional view, on a slightly reduced scale, taken on the line 7 7 on Fig. 4, looking down.
  • The'figures show the cushion as inflated.
  • the cushion 1 is of a modified bag-like character adapted to confine a body of air which inflates or fills it.
  • it has three elongated and approximately elongated elements 2, 3, 4, which are disposed lengthwise of the cushion and constitute main air chambers. The ends of these elements are connected by chambered edgings 5, 5, openings in which form air channels intercommunicating freely through the ends of. the elongated elements.
  • They upper sides 6 of the edgings 5 are raised above the general line of the upper surface of the elongated elements 2, 3, 4, and are preferably brought down to those surfaces by inclined slopes 7, 7.
  • these edgings 5 are disposed several tube elements, as 8, 9, 10, and 11, forming air channels or ducts which intercommunicate freely with the elongated elements 2, 3, 4, and extend between them so that the confined air may have free passage through these tubes from one to the other of the elongated elements 2, 3, 4.
  • these tube-like elements merge with the elongated elements 2, 3, 4, they are raised above the general surface of the latter, their sides being sloped down to merge with the elongated elements.
  • the tubes retain this same general formation, their under sides, however, being simply curved or extended downward somewhat so as to enlarge the capacity of the tubes.
  • the space between the elongated elements and the tubes is preferably taken up by more or less complete webs at 12, 12, 12, which are shown in the drawings as being solid, al-
  • An air valve 15 is placed at a suitable point to permit the attachment of means for inflating the cushion.
  • a supporting frame 16 is preferably provided for the cushion which may have an intermediate bearing element or elements 17, and frame elements 18, 19, 20, 21, so that the ends of the elongated elements of the cushion may be supported, as also the bottoms of the exterior ones of those elements medially, while the intermediate elongated element may be supported by some direct medial support. It should be understood that the character of this supporting frame may be varied as the particular requirements of use of the cushion make it desirable, so long as sufficient support is afforded to preserve the general contour of the cushion during use.
  • the whole cushion is, preferably, integral, with the exception of the valve; and in prac tice .I have found it satisfactory to make the cushion entirely of a compound which em- Eodies the elasticity and flexibility of rub- It is not intended to have the cushion stretch, materially, as a whole. Rather it is intended that the cushion shall retain its general shape and that there should be little change or distortion of its under side during use.
  • the substantially straight, elongated elements and the substantially straight edgings, disposed transversely of the elongated elements, withthe connecting web elements, serve to quite effectually preserve the general more or less rectangular shape of the cushion.
  • the top surface of the cushion has a waved or wrinkled contour due to the presence of the raised tops 6 of the edgings 5 and of the tube elements 8, 9, 10, and 11.
  • that portion of the cushion may be pushed down, so as to yield locally, without thereby materially stretching the rubber surface as a whole through the elasticity of the rubber, or drawing in the edges ofthe cushion material.
  • the cushion will yield readily at various points to accommodate itself to the person of the user, and without substantial alteration in its general marginal shape.
  • An integral, pneumatic air cushion made in a single piece with a continuous outer surface and embodying a plurality of main air chambers and intercommunicating air channels connecting the same, the carrying face of the cushion being wrinkled most markedly longitudinally, while the under surface is wrinkled most markedly transversely, and the faces being joined by a marginal web element whereby the carrying face of the cushion is adapted to spread lengthwise more readily than the opposed face.
  • An integral,pneumatic air cushion made in a single piece with a continuous outer surface and embodying a plurality of main air chambers and intercommunicating air channels connecting the same the under face of the cushion being disposed in comparatively straight transverse lines, and the carrying face of the cushion being disposed in irregular transverse lines whereby it is adapted to spread lengthwise more readily than the opposed face, and the faces being joined by a marginal web.
  • An integral, pneumatic air cushion embodying a/plurality of main, elongated air chambers, and intercommunicating air channels connecting the same, the under surfaces of the main elongated air chambers being comparatively straight, longitudinally, while the upper surfaces of such air chambers are undulated longitudinally, whereby the carrying face of the cushion is ermitted to spread lengthwise, by the flattening out of the undulfations, more readily than the opposed surace.
  • An integral, pneumatic air cushion made in a single piece with a continuous outer surface and embodying a plurality of main, elongated air chambers, and intercommunicating air channels connecting the u per portions of the same, the under surface 0? the cushion being comparatively straight longitudinally and undulated transversely, while the upper surface of the cushion is undulated longitudinally, and also transversely but to a substantially less degree than the under surface the upper and lower surfaces being joined by a marginal web whereby the under face may spread most readily transversely, and the upper surface may spread most readily longitudinally.
  • An integral, pneumatic air cushion embodying a plurality of main air chambers and intercommunicating air channels connecting the same, the material of the upper and of the lower sides of the cushion being disposed in irregular surface lines in one direction and in less irregular surface lines in the relatively transverse direction, whereby each side shall have the capacity of stretching more readily in one direction than in a relatively trans- ,versedirection, and the sides being so disposed that the lines g f greatest stretchability of one side lie transverse of the similar lines of the other surface, the sides being joined by a marginal web, whereby the greater stretchability of one side is opposed by the lesser stretchabih'ty of the other side.
  • An integral pneumatic air cushion embodying a plurality'of elongated air chambers having sides and bottoms approximately straight longitudinally and up er surfaces undulated longitudinally thereo and transversely disposed air ducts connecting the chambers.
  • An integral, pneumatic air cushion embodying aplurality of elongated air chambers havin sides and bottoms approximately straighfiongitudinally and u per surfaces undulated longitudinally thereo and transversely disposed longitudinall undulating air ducts connecting the cham rs.
  • An integral, pneumatic air cushion embodying a plurality of elongated air chambers having sides and bottoms approximately straight longitudinally and upper surfaces undulated longitudinally thereof, and transversely disposed longitudinally undulating air ducts having flattened tops and outward- 1y sloping sides connecting the chambers.
