CUSHIONING DEVICE FOR SEATS AND THE LIKE Filed June 27, 1934 2 Sheets-Sheet 2 Patented July 16, 1935 UNITED STATES 2,008,392 CUSHIONING DEVICE FOR- SEATS AND THE Maximilian Heller, Vienna, Austria Application June 27, 1934, Serial No. 732,676
In Austria August 31, 1933 3 Claims. (Cl. 155-179) This invention relates to a cushioning device for seats and the like of the kind comprising a plate attached by means of resilient, tensile supporting members to the seat frame, and the invention consists in various improvements of the device as hereinafter set forth and claimed.
In the first place plateand supporting member are so arranged at the seating edge as to occupy a projecting position in order to render the edge resilient. Moreover, when the cushioning device is applied to the back rest of the chair, means are provided for maintaining the plate in a forwardly projecting position relative to the frame. Means are also provided, in conjunction with the back frame, for covering the plate and supporting members with a detachably arranged cushion.
The invention is illustrated by way of example in the accompanying drawings in connection, with an arm chair.
Fig. 1 shows a skeleton of the chair in perspective view,
Fig. 2 is a similar view showing a modification of the cushioning element,
Fig. 3 is a perspective rear view of an additionto the principal cushioning device,
Fig. 4 is a perspective rear view of a chair to which this addition, partly broken away, has been applied, and
Fig. 5 is a perspective, fragmentary view of the addition.
The cushioning device comprises a platewhich is maintained in a floating position relative to the supporting frame by laterally extending, elastic elements. Fig. 1 shows the device as applied to an arm chair having a seat frame a and a back frame d. The longitudinal members of the frame a. are interconnected by means of cross members b and c, and those of the back frame are interconnected at the top by a cross member 6. The cushioning plate, which is parallel to the longitudinal frame members and much narrower than the frame, is bent at o in Fig. 1 to form a seat portion f and a back portion h. The seat portion of the plate is kept in its floating position by means of coil springs g which are strung between the plate and the longitudinal frame members. The upper end of the back portion-is secured to a bow spring 7c, and itis further supported by coil spring 11. connected to curved leaf springs m. The springs It and m maintain the plate portion h in an advanced position relative to the frame 11. This is a particular feature of the invention.
As a further feature of the invention, it should be noted that the front end of the plate 1 and the supporting members g at this end occupy a projecting position relative to the cross member I) of the frame a, thereby producing a resilient seating edge.
' In the modified arrangement shown in Fig. 2, the cushioning plate is made in two separate portions f and h one for the seat and the other for the back rest. The portion f is supported by coil springs g as 'already described. The por tion h is supported-by two sets of springs m, 11. and in addition by two coil springs Z which replace the cross; member e of the former construction and which thus provide a back rest with a resilient top edge.
While the upholstery of the chair can be carried out-in. any. convenient manner, the back rest of the chair is preferably treated as illustrated in Figs. 3 5. A cushion 10, adapted to cover and bear against the plate It or 11. and the supporting springs, is connected at the top edge to a sheet q adapted to cover the rear surface of the chair. The sheet q is connected to the rear faces s of the frame at in a. detachable manner, preferably through the medium of press buttons r. This arrangement allows the cushioning springs full freedom of movement.
In the absence of the cross member e of the back rest, the spring elements may be comple mented by a flexible steel strip zinterposed between the sheet q and the upper edge of the cushion p. The ends y of the strip may be bent at an angle and adapted to enter slots 22 in the frame members to which they can be locked by means of lugs :12 which are bent ofi from'plates u and adapted to engage the members y.
The device may be modified within the scope of the invention as defined by the appended claims. For instance the cushioning plate or plates may be divided longitudinally into two or more strips which are spaced and interconnected by springs. Springs may also be used for interconnecting the contiguous ends of the plates f and h in Fig. 2.
I claim:
l. A chair comprising a seat frame having side members and a front member which is lower than theside members, a back frame connected to said seat frame, a cushioning plate for each frame arranged parallel to the side members thereof, resilient tensile supporting members strung between the side members of the seat frame and the appertaining cushioning plate for holding the latter in a floating position above the level of the front member of the frame, curved leaf springs connected to and projecting forward from the side members of the back frame, and
resilient tensile supporting members strung between said leaf springs and the appertaining cushioning plate for holding the latter in a forwardly projecting position relative to the frame.
2. A chair as claimed in claim 1 wherein the cushioning plates of the two frames are combined into one structure. 7
3. The structure claimed in claim 1 in combination with a flexible steel strip arranged as a top member on the back frame, and means on said latter frame for holding the ends of said steel strip in a slidable manner.
