AIR-CUSHION Filed March 2, 1965 2 Sheets-Sheet 2 INVENTOR. H/DEJ/RO YHG/ BY WWW MTM/vEys United States Patent 3,316,567 AIR-(IUSHION Hirlejiro Yagi, 2548 Oaza Kolrubunji, Kokubunji, Tokyo, Japan Filed Mar. 2, 1965, Ser. No. 436,593 Claims priority, application Japan, May 21, 1964, 39/49,449 6 Claims. (Cl. 348) The present invention relates to an air-cushion.

More particularly, this invention relates to a novel aircushion comprising a pair of flat-shaped bag-like air chambers made from air-tight as well as water-proof material and bonded to each other at least on the upper fringes thereof, said air chambers being folded over at said fringes so as to make inner walls of said air chambers face each other; an air cock communicating with the air chambers for regulating the air contained in said air chambers; and a skirt part made integral with said inner walls and extending outwardly from the lower frin-ges thereof, said skirt part having the length substantially equal to a raincoat and being seamed water-tightly down the back thereof.

An object of the present invention is to provide an aircushion which can serve, beside its own primary use, as a cushion upon which one can lie reclined and also as a rain wear.

Other objects of the invention will be apparent through the following detailed descriptions of the invention.

In the drawings which illustrate an embodiment of this invention:

FIG. 1 is a perspective view of the air-cushion according to this invention;

FIG. 2 is a cross sectional view taken on the line 11-11 of FIG. 1;

FIG. .3 is a cross sectional view in part of the collapsible skirt part seamed to the lower fringes of the air chamber;

FIG. 4 is a cross sectional view in part taken on the line IVIV of FIG. 1;

FIG. 5 is a side elevational view of the air-cushion as the skirt part is self-contained therein; and

FIG. 6 is a front view of the air-cushion serving as a rain coat.

In the drawings, numeral 1, 1' are a pair of air chambers each made from airtight material snuch as rubberized cloth or thin elastic films of synthetic resin and each having four fringes or layers, that is, upper and lower fringes 2, 2 and front and rear fringes 2", 2". The upper and rear fringes are seamed together by suitable adhesives. An air cock 3 is provided to the rear fringes 2" by which to pump the air into said air chambers 1, 1 simultaneously, a collapsible ski-rt part 4 being formed by a thin Waterproof material such as films of synthetic resin having upper ends extending from and made integral with the inner sides of said lower fringes of said air chamber 1, 1' and provided with button holes 5 on the front side thereof and buttons 6 on the corresponding front side thereof. Though in the embodiment illustrated in the accompanying drawings, the rear fringes 2" are seamed together and the air cock 3 is provided thereto, said fringes may be kept unseamed and the air cock may be provided to other fringes.

This invention, as above-described, consists in a pair of air chambers with the fiat sides facing each other and with the upper fringes seamed to each other and a collapsible skirt part seamed to the lower fringes of said air chambers and may be utilized as a cushion in a sittingroom, in the first place, with collapsible skirt part dis posed within the space composed between the air chambers 1, 1' and air pumped into said air chambers 1, 1' through said cock 3, and secondly as an air pillow in the 3,316,567 Patented May 2, 1967 ice open fields with air chambers expanded with air and collapsible skirt part 4 drawn out and spread full on the ground so that one may lie on the extended skirt part lengthwise without staining the wearing apparel, and thirdly as a rain wear, with the air chambers half filled with air and the front sides thereof fiared open and said collapsible skirt part drawn out, wherein said drawn out part serves as a rainproof apparel and the air chambers as a hood.

Also, 'the air chambers discharged of its air contents can be collapsed into a small size and carried easily. It is significant that the air cushion which this invention provides can serve three purposes regardless of the very simplified structure comprising air chambers 1, 1 folded together and seamed at the upper fringes and collapsible zkirt part attached to the lower fringes of said air chamers.

What is claimed:

1. A combination air-cushion and head cover comprising, first and second inner layers of material of substantially coextensive length and width having one pair of their corresponding sides and their corresponding top ends sealed together to form a hood opening at the opposite corresponding sides, and an enveloping layer sealingly connected adjacent the top ends of the respective first and second inner layers and overlying the exteriors of said first and second inner layers and extending downwardly along the respective sides thereof and being sealingly secured around their peripheries to the respective sides of said first and second inner layers to define inflatable substantially aligned pillow chambers on each side of said hood.

2. A combination air-cushion, according to claim 1, wherein said first and second inner layers of material are substantially rectangular, said enveloping layer forming substantially rectangular pillow chambers with said first and second layers on respective sides of said hood which are coextensive in width and length.

3. A combination air-cushion, according to claim 1, including inflation means extending from the exterior of said hood into each of said pillow chambers for inflating said pillow chambers.

4. A combination air-cushion and head piece, accord ing to claim 1, wherein at least one of said first and second layers of material is longer than said enveloping layer and defines a protective cover extending outwardly from said pillow chambers for supporting the body of a person whose head rests on said pillow chambers.

5. A combination air-cushion and head piece, according to claim 1, wherein each of said first and second layers are longer than said enveloping layer and define a cap, said first and second layers being foldable in overlying relationship to also define a protective covering extending downwardly from said pillow chambers which may be spread on the ground alongside the pillow chambers of said hood to provide a support for a persons body when resting the head on the pillow chambers.

6. A combination air-cushion and head piece, according to claim 1, wherein each of said first and second inner layers extend downwardly from said hood and define a cape, said first and second layers having respective opposite corresponding sides with complementary arranged buttons and button holes for securing said cape.
