states "PATENT CFFICE 2 Claims.

My invention particularly relates to a cover for dental chairs which will be a universal fit for any standard make of dental chair, and which will wear well and can be readily and conveniently cleaned, and from the use of which the occupant of the chair derives a maximum of comfort. More particularly, the invention relates to a cover having a lacquer-coated or glazed woven fabric outer surface, against which surface the occupant of the chair rests or leans, and a flexible fabric inner surface of imitation leather, or other suitable material, which engages the outer surfuze of the usual seat cushion or chair back support of the dental chair, together with a suitable pad between the outer andinner cover surfaces to give a cushioning effect, and suitable means for tightly securing the cover to the chair cushion. The invention also includes suitable lacquer-coated fiber or glazed woven fabric covers for the chair arms.

The annexed drawing and the following description set forth in detail certain means embodying my invention, such disclosed means constituting, however, only a few of the various forms in which the principle of the invention may be embodied.

In said annexed drawing:

Figure 1 is a perspective view of the upper portion of a dental chair of standard design, including a seat cushion, a chair-back support, and arms, provided with my improved covers;

Figure 2 is a top plan and Figure 3 is a bottom plan of the cover for the chair-back support of a dental chair;

Figure 4 is a top plan and Figure 5 is a bottom plan of the cover for the seat of a dental chair;

Figure 6 is a fragmentary transverse vertical section, upon an enlarged scale, taken in the plane indicated by the line 6-6, Figure 4;

Figure 7 is a side elevation and Figure 8 a plan view of my improved cover for the arms of the ental chair;

Figure 9 is a transverse section, taken in the plane indicated by the line 99, Figure 7; and Figure 10 is a horizontal section, taken in the plane indicated by the line Ill-l0, Figure 7.

Referring to the annexed drawing in which the same parts are indicated by the same respective numbers in the several views, I show in Figure 1 the upper portion I of a dental chair of standard construction having a seat cushion 2, a chair-back support 3, and arms 4. For the seat cushion 2, I provide my improved cover 5, and for the chairback support 3 my improved cover 6, and for the arms 4 my improved covers 1.

The seat and back covers 5 and 6, respectively, comprise a substantially plane cushioning pad 8, Figure 6, having outer and inner surfaces of suitable character for the desired purpose, and preferably comprise a substantially plane felt cushioning pad 8 provided with an outer surface of lacquer-coated fiber or glazed woven fabric such as glazed linen. The cushioning pad 8 is also provided with an inner surface of flexible fabric material, preferably consisting of flexible leather or imitation leather or other suitable good-wearing material, such material being also, preferably, slide-resisting. Preferably, the outer and inner surfaces 9 and ID are separate members and are secured together, with the cushioning pad 8 securely fastened therebetween, by means of a peripheral leatherette binding II which is stitched to the outer and inner surface portions 9 and I0 adjacent the peripheral edges of the latter, and thus provides a distinctive and attractive trim for the seat cover.

For fastening the covers 5 and 6 to the seat cushion 2 and the chair-back support 3, I secure to the inner cover surface portions Ill, and adjacent the peripheral edges thereof and under the binding H, a plurality of spaced and outwardly tapered flexible imitation leather straps or cars l2 which are of a length suflicient to extend around the oval side form I6 of the cushion 2 and the side frame ll of the chair-back support 3, and somewhat across the under side of the cushion 2 and the rear face of the chair-back support 3, as clearly shown in Figures 1, 3, and 5. These ears l2 are drawn tightly and neatly down around the oval side form 16 and the side frame I! and then extended across the inner surface portions of the cushion 2 and the chair-back support 3 for secure fastening of the covers to the cushion and chairback support through the use of draw cords which pass through suitable loops l3 formed by suitable stitching adjacent the free edges of the ears [2. Preferably, I utilize for the seat cover 5 a draw cord I4, Figure 5, formed of endless elastic mate rial, and for the back cover 6, Figure 3, a cloth tape l5, the ends of which can be tied together so as to provide sufficient tension securely to hold the cover 6.

For the arms 4 of the dental chair I, I provide covers 1, Figures 7 and 8, formed from lacquercoated fiber material or glazed woven fabric such as linen, these covers I being of channel-shaped construction, Figure 9, and of suitable length for the particular chair arm 4, so as substantially to encase the top and sides of the arm 4, as is clearly apparent in Figures 1 and 9. The covers I are also provided with a trim consisting of a peripheral leatherette binding, as clearly shown in Figures 7 and 8. To hold the arm covers I from sliding rearwardly on the chair arms 4, I provide end caps 2| of hooded formation and formed of leatherette or other suitable wear-resisting material, and of a character and color to provide a distinct trim which shall conform to the trim II of the seat and back covers and the trim binding of the cover I and also conform to the leather of the chair proper, these caps 2! having front portions 22-, Figure 10, adapted to engage the front ends of the arms 4 and rearwardly extending side portions 23 which are extended at their ends within the front end of the channel-shaped cover 1 and secured therein by stitching 24. Secured within the channel-shaped arm covers I and adjacent the spaced lower peripheral edges thereof are two spaced pairs of opposed ties 25 which are tiedtogether under the chair arms 4 securely to fasten the covers I to said chair arms.

Inasmuch as the body portion of my improved chair cover does not for any standardmake of dental chair extend substantially over the oval side forms I6 of the seat cushion 2 and the side frame II of the chair-back support 3, the covers and 6 are suitable for use with any standard make of dental chair, since, it is evident, the covers 5 and 6 will conform to any standard size of seat cushion or chair-back support without detriment to the essential service qualities or the pleasing appearance of the cover, the side ears I2 and the adjustment derivable from the draw cords I4 and I5 providing whatever ad iustment is necessary for securely fastening the covers to different sized cushions and chair-back supports. Furthermore, the lacquer-coated or glazed woven fabric outer surface portions of my improved covers would not lend themselves to a perfect forming over the continuous oval side forms I6 of the chair cushions 2 or the side frames I! of the back supports 3 without injury to the covers, so that the flexibility necessary for accommodation to these continuous oval side forms I6 and side frames I1 is provided in my improved cover by the flexible ears I2 which are secured to the substantially plane main cover portions which engage substantially only the outer faces of the cushion 2 and the back support 3.

I direct particular attention to the fact that my improved cover construction is cool for the patient to sit upon and lean against, that it will not stick to the patient, thus avoiding considerable annoyance by reason of the patient perspiring, and that the lacquer-coated or glazed woven fabric, such as linen, of which the outer surface portion is comprised, permits the patient easily to move upon such outer cover surface. I also point out that my improved cover does not require usual washing and cleaning, such as laundering, but can be kept clean with a damp cloth, since the outer surface 9 is water-proofed. Preferably, the inner surface Ill of my improved cover is formed of slide-resisting or friction fabric material so as to prevent the cover from readily moving relatively to the outside surface of the chair cushion 2 or back support 3 which it engages.

What I claim is:

1. A cover for a dental chair part consisting of a substantially plane intermediate fabric pad member, a glazed woven fabric moisture-proofed outer support member, a flexible wear-resisting and slide-resisting inner member, a peripheral leatherette binding securing together said outer, inner, and intermediate members, spaced flexible straps secured to said inner member and of a length suitable to pass around the free edge of, and extend under, a chair cushion or chair-back support, said straps being formed with securing means for a draw cord, and a draw cord adjustably held by said securing means.

2. A cover for an arm of a dental chair comprising a glazed woven fabric member of channel construction having a peripheral leatherette binding, a leatherette wear-resisting hooded end cap for said member having an extended marginal portion secured to said member, and means for removably fastening the cover to the chair arm.
