INEUMATIC CUSHION.
Specification of Letters Iatent.
Patented Jnne ig, new.
Application filed August 10, 1915. Serial No. 44,816.
T all whom it may concern:
Be it known that I, ANTON C. Eccrns, a citizen of the United States, residing in and State of New York, have invented certain new and useful Improvements in Pneumatic Cushions, of which the following is a full, clear,
- and exact description.
This invention relates to pneumatic cushions, especially adapted for use by persons sufiering from inguinal hernia, Brights disease, or other ailments which produce inflammation or cause sensitiveness in the lumbar regions. Cushions made according to this invention are also adapted for the use of persons afflicted with disorders which cause such frequent urination that it is impracticable to disturb the patients sitting position. 7
It is the object of this invention to provide a cushion constructed in such a way that when in use there is no contact with the inflamed or sensitive parts of the body of the user. Afurther object of this invention is to provide a cushion formed so that the patient may without discomfort or substantial change'of position accomplish the frequent urination necessitated by such disorders.
I accomplish my cushion having its main object by forming a load supporting or shape with a restricted connecting portion joinin the ends and adapted to prevent sprea mg of the sides by the internal fluid pressure or by the weight of the person seated thereon,
For a clearer understanding of my invention reference is made to the following description and to the accompanying drawings in which:
The figureis a plan view of apneumatic cushion made according to this invention,
The preferred construction of my cushion is substantially as follows:
A plurality of pieces of rubberized fabric are joined by cement about their margins at and b to form an air-tightbag o, the usual valve '1) being provided to permit inflation. The method of'building up the structure is that ordinarily employed in the manufacture of hollow rubber goods and forms no part of my invention, the novel feature. bemg the formation of the front part thereof s9 that it does not contact with the sensitive parts of the body ofthe user, or form an obstruction in case it is necessary for him to urinate. This I-accomplish by restricting the front portion to a relatively small arched connecting element 03 between the s1des of the cushion c and spanning the space therebetween. The part 05 is arched. outwardly to avoid the sensitive parts of the body and defines an enlargement the central opening through the cushion. While it-may be formed of any stifi substan: tially inflexible material, I have found stifi' rubber tubing to be well adapted to this use, principally because it can be firmly joined to the. material of the cushion at the points g and 71 either by cement or vulcanization.
The part d is adapted to project beyond the edge of. a chair seat upon which the cushion may be placed, and forms a forwardly extending reduced portion of the. central opening. To permit urination by the occupant the part cl may be bent down out of the horizontal plane in which it normally lies. Little eifort is required to accompllsh this as the forwardly projecting central portion provides leverage to permit turning. I
To provide sufiicient supporting area'to the cushion I provide the inwardly projecting parts e and f. These make the cushion much more comfortable for the occupant, without, however, interfering with the functions mentioned above.
A cushion built according'to this invention permits the use of a portable urinal without any necessity for disturbing the patients sitting position, a downward bending or turning of the art (I of the cushion over the edge of the 0 air seat upon which it is placed removing all obstruction in front of the occupants body.
While I have described this cushion as formed of rubberized fabric, the various parts of which are joined by cement, I do not limit myself to that construction, as I may equally well form the article of sheet' or molded rubber, and I wish to be understood as including such a construction as in the scope of my invention.
What I claim as my invention is:
1. A pneumatic cushion comprising an inflatable load supporting seat part having a comparatively large opening L interior thereof, and a restricted pant of j through the substantially inflexible material spanning the front to overcome spreading and to give continuity to the seat, said restricted part being directed forwardly toward its center to provide leverage therefor to permit said part to be turned downwardly when the seat is supporting the load.
2. A pneumatic cushion comprising a horse-shoe shaped seat portion of limp flexible material and an arched relatively still connecting element of reduced cross-section connecting the ends thereof and adapted to retain said seat portion in its normal form under internal fluid pressure.
3. A pneumatic cushion comprising ahorse-shoe shaped seat portion of limp flexible material and an arched relatively still element of relatively smaller cross-sectional area connecting the ends of said seat porlieing uninliatable and of relatively smaller,
area in cross-section than the parts constituting the sides and rear and forming a forwardly extending reduced portion of the.
central opening through the cushion.
