following is a specification. v
My present invention relates' generally to upholstery and more pai-ticularly to up-v holstery of an inlatabletype, the object of my invention being to provide strong and durable cushion pads applicable to various uses including the seats and backs of variousarticles of furniture and vehicles and also capable of utilization in the form of an independent cushion. v
My invention is capable of various forms,
, certain of which are shown in the accomthis specification,
panying drawings, which form a part of and in which-- Figure lis a view. partly in plan and-partly broken away and in section illustrating a rectangular multi-celled cushion constructed in accordance with my invention. j Fig. 2 is a vertical section on a substantiallyenlarged scale taken therethrough on substantially line 2-2 ofF ig. l. Fig. 3 is a vtransverse sectional view taken therethrough substantially on line 3-3 of Fig. l. Fig. 4 is a view similar to Fig. l illustrating the use of a plurality of independent filling channels in connection,
with a rectangular cushion of a multi-celled type. Fig. 5 is a similar view illustrating the cushion shown in Fig. 4, with a surrounding flange, and Fig. 6 is a vertical section, taken on an enlarged scale, vthrough a portion of Fig.l 5, substantially on line 6-'6 of said figure.
Referring now to these figures and particularly to Figs.l 1, 2 and 3, I' provide a generally rectangular Icushion A, the body of which is formed of a yplurality of parallel rows of inflatable cells, each of which rows is separated by an air channel B and each of which cells is generally triangular in form, it being particularly noted that the cells of each row or Yseriesare alternately reversed with respect to one another, alternate cells C having their apices opening in onedirection and the other cells C having their apices opening in relatively opposite directions. The'body of the cushion so formed is surrounded by a continuous rib D, the end portions and one side portion of which are respectively provided with air channels D Texas, have invented an' Improvement in'Upholstery, of which the on al similarly enlarged scale and D2 and to one corner of which is connected a filling valve D3 of suitable type. Thus the several cells of the several rows thereof, opening in alternately opposite directions, are 1n communication with the sevthese several chanof the cushion as eral channels B and D, nels opening at one side particularly seen in Fig. l, into the main air channel D2 at one end of which the filling valve D3 is connected.
In Fig. 4 practically the same arrangement of the rows of cells E and E is carried out together with the surrounding rib F with its end channels F and the intermediate channels G between the several rows of cells are each extended at`one side of the f pad and provided with an independent lilling valve F2 and G.
In Fig. 5 the arrangement shown in Fig. 4: is duplicated with the addition of a flat surrounding iiange Gr2 beyond the surrounding rib F, as more clearly shown in the detail F ig.v 6.
Thus from the foregoing Vit will be seen that my invention provides a simple and' compact inflatable cushion which will be at once strong and durable and in which the usual disadvantages of puncture are practically eliminated. Various flexible materials impervious to air are suitable in the formation lof the cushion thus shown and described and it is to be understood that as to material, size and general outlines the cushions are to be formed as best seems to accord with the ultimate use in mind, either lined or unlined, covered or uncovered, tufted or untufted, as desired. Y
I claim: e
l. A flexible inflatable cushion of the character described, the .body of which has a surrounding rib provided in relatively opposite portions thereof with air channels, the said body of the cushion having a series of spaced air channels Yparallel with the said air channels of the rib and also provided in acter described, the body of which has a surrounding rib and a plurality of rows of oppositely opening triangular cells and parallel air channels between and along the se- 5 ries of air cells and in communication with alternate cells of adjacent rows thereof, and certain of which air channels are formed in portions of the surrounding rib, together with means for admitting air to the several 10 air channels, all as set forth.
3. A flexible inflatable cushion ofthe charair channels.
acter described, the body of which has a surrounding rib and consists of a plurality of rows of oppositely opening triangular cells and air channels communicating with alter- 15 nate cells of adjacent rows thereof, together with means for admitting air to the several LAURA L. DODD. Witnesses:
