Serial No. 614,980 8 Claims. (Cl. 155-184) This invention relates to a chair structure, and has to do primarily with a chair seat of the padded type which is so constructed as to resemble a saddle seat in appearance and at the same time possess the advantages of a padded seat.
As ordinarily made, saddle seats for chairs are constructed of wood so shaped as to produce the so-called saddle seat effect. While such seats are usually attractive in appearance, they do not have the advantages from the standpoint of the comfort of the user that are possessed by a chair seat of the padded type. It is an object of this invention, therefore, to produce, in a chair seat, a saddle seat appearance without de- 16 tracting from the advantages of a padded seat, this object being attained by utilizing a flexible bottom or base member having forming pads on the upper face thereof, suitably combined with padding material and a wear resisting covering 29 of any desirable type. It is a further object of the invention to provide a chair seat which resembles a saddle seat in appearance yet is sufliciently flexible to conform to a considerable extent to the bodily movements of the user of the chair. A
26 further object of the invention is the provision in a chair seat of a construction which, although not detracting from the appearance thereof, pre-' vents the 'seat from marring desks and other articles of furniture with which the chair may be 80 used and with which it may come in contact. It
is a still further object of the invention to provide a chair seat which is attractive in appear- .ance and at the same time one which is unusually comfortable for the user. Still other objects of the improvement will be apparent from the following description, taken with the accompanying drawings, wherein:
Fig. 1 is a perspective view of the improved chair seat, with the base and back partly broken away; I
Fig. 2 is a plan view of the improved seat, with parts thereof cut away to show the interior construction;
Fig. 3 is a side elevational view of the improvement;
Fig. ,4 is a front elevational view thereof;
Fig. 5 is a rear elevational view thereof;
Fig. 6 is a vertical sectional view from front to rear through the improved seat, taken on the line 6--6 of Fig. 2;
Figs. 7, 8 and 9 are transverse sectional views taken on the lines 7-'7, 88 and 9-9 respectively of Fig. 2; and
Fig. 10 is a sectional view of a portion of the 55 seat taken on the line 10-10 of Fig. 2.
The body or bottom portion of the improved seat comprises a base 10 made of any suitable flexible material. although ply-wood has been found most satisfactory for this purpose. In plan, the base may be given any shape desired, although 50 the outline shown in Fig. 2 has been found advantageous for use with revolving chairs of the typewriter type. The base portion is preferably so formed or shaped as to provide a plane, central section 11 of substantial width extending from the front to the rear of the seat, and the marginal portions 12 formed in such a manner as to incline upwardly to a slight extent from the side edges of the plane, central section 11, as shown in Figs. 7, 8 and 9.
In order that the effect or appearance of a saddle seat may be produced, a forming pad or roll 13 is secured along the outer edge of each of the marginal sections 12 as shown in Figs. 2, 'l and 9 of the drawings. The forming pads 13 are ordinarily made from a strip 14 of felted burlap or similar material folded about a plurality of strands 15 of twisted hemp or jute fiber, with the edges 16 and 17 of the strip stitched together as indicated at 18. The pads are secured to the base by means of small tacks 19 driven through the stitched edges 16, 17 into the base. A forming pad or roll-of this character possesses sufllcient flexibility and resiliency for this purpose, and at the same time it is sufficiently rigid to maintain the proper shape and, the attractive appearance of the finished seat. The length of the strip of forming pad 13 utilized along each outer edge of the seat should be sufficient to produce whatever saddle effect may be desired, and it will be understood that the size of these forming pads, both the length and the transverse dimensions, should be such as to produce the desired effect in the particular chair seat under construction.
In addition to the forming pads 13 placed along the side edges of the marginal sections 12 of the base, it is desirable to utilize a relatively short length of forming pad 21 at the front of the seat, preferably centrally thereof, and extending from the front edge of the base 10 backwardly along the center line thereof. The forming pad 21 is constructed in a manner similar to the forming pads 13 heretofore described, and may be secured to the bottom of the seat by small tacks 22 extending through the stitched edges mm the base in a manner similar to that in which the forming pads 13 are secured to the outer edges of the base.
The base of the seat, with the forming pads thereon, is then covered with suitable padding material. Preferably the padding material utilized with the improvement disclosed herein comprises a layer of hair padding 23 in contact with the base 10, with a layer of cotton 24 placed upon the hair padding. This padding material covers the entire upper surface of the base, and preferably the layers of hair and cotton extend over the centrally arranged forming pad 21, and the layer of cotton extends the marginal forming pads 13. After the forming pads and padding material have been secured upon the base of the seat, a covering 25 of any suitable wear-resisting material is placed therebver and has its edge turned downwardly beneath the edge of the base 10 and secured thereto by small tacks or other suitablemeans. An edging material 26 may be secured beneath the edge of the base 10 so as to conceal the edge of the covering material and give a more finished appearance to the seat. Pref erably this edging material is of roll form and comprises a strip of material 27 similar to the covering material 25 folded around a cord 28 of fiber or twisted paper, with the overlapping edges secured to the under face of the base by means of tacks 29 as shown. If desired, the roll edging 26 may be so placed as to extend outwardly slightly beyond the downwardly turned edge of the covering material 25 so as to constitute a bumper for the chair and thus afford protection for the downwardly turned edge of the covering material.
As shown in Figs. 1, 2 and 6 of the drawings, the seat may bemounted upon a chair iron 30 of usual construction secured upon the upper end of a spindle 31 adjustably supported in a base 32. A back 33 supported from the iron 30, may also be provided. In an improved seat of the character disclosed herein, it is preferable to utilize a chair iron having a pair of side frame members 34 rigidly secured thereto, each of these side frame members having a pivotal connection 35 at its front end with a small angular member 36 secured to the seat by means of a bolt 37 extending through the base 10 and having a small piece 38 of canvas or burlap tacked over the head thereof to retain it in position before the seat is assembled upon the chair iron. Side frame members 39 are pivotally mounted at 40 at their inner ends to the forwardly extending side members and have their rear ends pivotally mounted at 41 upon angular bracket members 42 secured to the lower face of the base 10 of the seat in a manner-similar to that in which the forward bracket members 36 are secured thereto. The particular, manner in which the iron is constructed forms no part of the present invention, the same being disclosed and claimed in William A. Sengpiel application Serial No. 531,286, filed April 20, 1931.
It will be noted that in the construction disclosed herein the supporting portions of the chair iron are secured to the base 10 at points spaced a substantial distance from the front and rear edges of the base, and at a substantial distance from the outer edges thereof. Preferably these points of contact between the chair iron and the base are located adjacent the junctures of the central plane section 11 of the base and the upwardly inclined marginal sections 12. By supporting the seat upon the iron in this manner the inherent flexibility of the base portion of the seat permits the edges of the seat to bend downwardly, particularly the marginal sections 12 as shown by the dot and dash line position indicated in Fig. 7, and thus conform to the bodily movements of the user of the chair, the construction thus producing a chair which is much more comfortable to the user than chairs of this general type heretofore known.
It will be noted furthermore that the forming pads 13 are of such length and preferably so arranged along the outer edges of the base portion 10 that the front ends thereof terminate a substantial distance from the front edge of the base portion, and these pads extend rearwardly, conforming to the outer edges of the base portion, and terminate a substantial distance from each other, that is, near what may be regarded as the rear corners of the seat. This arrangement of the marginal forming pads provides a construction whereby the side edges of the chair seat possess sufficient body and rigidity to withstand long use and still maintain the shape of the seat. By locating the forming pads 13 in this manner, they serve to position the occupant of the chair without any effort upon the part of the occupant.
By terminating the rear ends of the forming pads 13 at the positions and in the manner heretofore described, a depressed portion 43 is produced at the rear edge of the upper face of the seat. This feature has been found to be of importance in that it adds to the comfort of the chair seat and is unusually effective in providing correct and easily attained posture for the occupant.
The front ends of the forming pads 13, in conjunction with the forming pad 21 at the center of the front edge of the seat, produces along the front edge of the finished seat the two depressed portions 44 located on opposite sides of the pad 21. These depressions likewise serve to properly position the occupant on the chair and this position is easily maintained during all ordinary movements of the occupant. In other words, when the improved seat is employed with a revolving type of chair. all usual turning movements of the occupant are readily transmitted to the chair seat thus obviating the objection to many chair seats heretofore known, wherein no effective means has been provided to prevent relative movement of the occupant with respect to the chair seat in the ordinary turning movements of the occupant.
While a preferred form of construction of the improvement has been described herein and illustrated in the drawings, it will be understood that various changes may be made in the invention as it has been disclosed so long as they do not depart from the improvement as particularly pointed out in the appended claims.
The invention having thus been described, what it is desired to secure by United States Letters Patent is:
