DENTAL CHAIR HEADREST COVER Application filed October 2, 1929. Serial No. 396,859.
This invention relates to accessories for dental chairs and the like and particularly relates'to a sanitary coveringmeans for the head-rests of such chairs.
The general object of this invention is to provide an improved sanitary cover for the head-rest cushions of dental chairs which is simple in construction, easily and quickly applied and removed, economical of manuib facture, and easily laundered.
Further objects and advantages of the present invention will become apparent from a study of the following specification and appended drawings, in which Fig. 1 is a view in perspective showing the head-rest of a dental chair with the headrest cover in place.
Fig. 2 is a transverse section through the head-rest cover showing the manner in which 2 the head-rest cover protects the head-rest cushions.
Fig. 3 is a plan view of one form of the head-rest cover. I Fig. 4 is a section taken on the line 22 of Figure 3. 1
Fig. 5 is a plan view illustrating a modification of the construction shown in Figure 3.
Fig. 6 is a section taken on the line 6-6 of Figure 5.
Fig. 7 is a view similar to Figs. 3 and 5, but on a reduced scale, illustrating a further modification.
Figure 1 illustrates the upper portion of i the back of a chair such as is commonly used by dentists or barbers, from the top of which projects a head-rest which, as shown in Figures 1 and 2, is provided with two adjustable pads, each supported by an adjustable mem- '40 her which is capable of adjustment relative to the back of the chair for the purpose of adapting the head-rest to persons having different heights and widths of head.
It has been found desirable in the dental art to protect the cushions of the head-rest for the purpose of preventing transmission of skin and scalp diseases due to contact with persons who may have such diseases. As a sanitary precaution it is customary to cover the cushions with some kind of readily cleanable and replaceable means such as a towel or specially prepared pad. In some instances paper has been used for the purpose while in other-cases specially shaped linen covers are provided.
The present invention relates more particularly to such covers for head-rests of dental or barbers chairs and comprises a sheet of fiexiblematerial 1 which, as shown in Figure 3, is composed of a single sheet of flexible material suchas linen toweling, for instance, folded zit/2. ,The upper edges and the right and left edges respectively, of the'two folded portions thus formed, are turned under and stitched by stitches 3 so asv to form a substantially rectangular envelope. A central line of stitches 4; extends from top to bottom, Figure 3, and divides the rectangular envelope formed by stitching the edges of the head-rest cover together into two compart ments or pockets. Each of the compartments or pockets formed by the central stitches 4 is provided with an opening produced by slitting one of the folds ofthe headrest cover by a vertical slit 5, which, as best shown in Figures 3 and 4, is edged with a suitable material to prevent ravelling.
The cushions of the dental chair head-rest are ordinarily adjusted somewhat at an angle to each other so that thehead of the person occupying the chair will lie firmly yet comfortably in the V-shaped space between the cushions. The central line of stitches 4 serves to make the head-rest. cover conform to: the angularity of the cushions and thus makes a neater appearance and at the same timeprevents any discomfort which might be caused by a badly fitting cover.
The head-rest cover produced in the man- .ner just described is used by'drawing the .cover over the cushions of the head-rest, this process being permitted by the slits 5 which allow the cushions to be slid into the compartments formed by the central line of stitches 4. The slits 5 are of sufficient length to make it easy to draw the headerest. cover over the cushions by manipulating the cover in asuitable manner manually until the cover is in place as shown in Figure 3, the central line of stitches 4: serving tocause the headrest cover over the head-rest cushions,a-modification is contemplated such, for instanceas is shown in Figures 5 and 6', or as is shown in Fig. 7. The slits 5 are provided withcem tral enlargements 6 formed by cutting out the material about the mid-point of: the slit and edging the slit and the enlargement with suitable material to prevent ravelling: This central opening makes it possible to draw tli'eliead-rest cover over thehead restcushionsmore easily'andat the same time pre Vents unnecessary stretching of them'aterial forming the liea'd rest cover, thus reducing thewear and tear on the head-rest cover. The generally ovate opening characteristic; of Fig; 7" also facilitates applying the cover.
If so desired; the central line of stitches maybe dispensed with although it is preferable to so stitch the head-rest cover for the purpose of causing the head-rest covermore ne'arlyto conform to the angularityxof the head-rest cushions.
While the invention has beenfshown and described as being composed. of a suitable fabric such as linen. t'oweling stitched along the edges, it is not the desire to limit the in vention to the precise embodiment shown, but itm'ay be'susceptible to variation-without departing from the spirit, of the invention; For instance, the head-rest cover might be composed of strong paper folded and pasted along the edges and slit in" the manner described herein. Such a construction would doubtless be much more economical and cheaper to manufacture as it would; permit furnishing a' clean head-rest overro1 each person who mayoccupy the chair,the cover Being discarded after use;
Ifdesired, a' variation in the: construction described herein might be used. in which the head restcover is made by stitching two oblong pieces offl 'exible material-,suclras linen fabric, together a'longf'our edges instead of ma'lfingthe "cover ofa single piece or fabric folded centrally. Y
Still another. variation might be used in which a single-slit or opening is provided for accommodating; one of the cushions of the head-rest, the head-rest cover being made somewhat s maller and adapted foraccommodating onl'y'one ofthe head-rest cushions.
Whatisclai1ned as newis :1". A; sanitarycover'comprising a rectangul'ar flexible sheet of material folded and sewed along three sides so as to form a closed envelope, said envelope being provided with acentral 'lineof stitches dividing said envelope into a plurality of compartments and also being provided with a plurality of slits each substantially centrally of each compartment.
2. A. head-rest cover for dental chairs and the like comprising a closed envelope of flexible material divided by a central line of stitching into two'-poc-kets; one wall of each otsaidpockets being provided with a central slit. for permitting the cover to be drawn over the head r'e'st" cushions.
3.. A coverforthe head rests of dentists chairs and the like having a pair of head rests,. comprising a: closed envelope divided into two compartments, the rear wall of each compartment b'ei-ng slotted to allow the: cover to lee-drawn over the pair of headfirestbs In testimony: whereofl hereby afii'xl' my;
