`Patented June 24, 1930 UNITED STATES PATENT OFFICE DESIRE H. VAN IIOVE, 0F ROYAL OAK, MICHIGAN, ASS-IGN OR TO L. A. YOUNG SPRING & WIRE CORPORATION, 0F D'ETROIT, v'.lVIICI-lIGrAN SEAT-CUSHION sTRUGTURE Application filed July 7, 1928. Serial No. 290,996'.

The main object of this invention is to provide a seat cushion structure which is Well adapted for use in automobiles which has the desired resiliency and 1at the same time the body springs of the cushion may be relatively loW.

A further object is to provide a seat structure for automobiles and the like in which there is a comparatively. small amount of relative movement between the seat and back When underload.

A further object is to provide a structure having these advantages which is simple and economical in its parts.

Objects pertaining to details andeconomies of my invention Will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing in. which Fig. 1 is a. fragmentary frontelevation of v a seat structure embodying my invention as adapted by me for automobiles. y

Fig. 2 is a detail vertical section on line 2 2 of- Fig. 1, only such parts being shown as are deemed necessary to illustrate an embodiment or adaptation of my invention.

Fig. 3 is a fragmentary plan view With the cushions removed.

Fig. 4 is a detail vertical section on a line corresponding toline 4 4 of Fig. 5, of a.

modified form or embodiment of my invention. v

Fig. 5 is a fragmentary plan vieW of the" cushion frame and the support for the.

cushion.

In the embodiment illustrated in Figs. 1 3

FI provide a supporting frame designated generally by the numeral 1 and having an upwardly pro]ecting support 2 at its rear end, and a\support 3 at its front end. A top support 4 is provided which may be a part' of the back of the seat or .is mounted on the back of the seat frame.

A cross bar 5 is disposed adjacent the i rear support 2 and suspended therefrom by means'of thespring hangers 6. Frein this cross bar is a back supporting unit 7, the upper end of Which is suspended from the coiled springhangers 8 carried by the support 4. i

The bottom straps or`slats 9 are preferably formed of flexible strips of metal and are connected to the. cross bar 5 at their rear ends by means of the coiled springs 10 While they are connected at their front ends to the support 3 by means of the coiled springs 11.

Cross ties or springs 12 are provided to prevent the separating of the straps under load.

The seat cushion unit designated generally by the numeral 13 is supported by this bottom cushion unit, in the embodiment illustrated consisting of a plurality of coiled body springs 14 arranged' in pockets 15 in a suitable casing having top and bottom Walls 16 and 17. The springs 14 are thus supported in an upright positionA and flexibly connected so that the load 0n a group of the springs is transmitted to the supporting straps 9 Which, owing to beingspring supported, yield under the load. The spring unit is shown With upholstery 18.

The back cushion unit consists of a base -frame 19 With coiled springs 20 mounted thereon and provided with upholstery 21. This back unit is supported above Athe rear edge yof the seat cushion and against the back support 7.

In the embodiment shown in Figs. 4 and 5 the front and rear support members 22 and 23, respectively, .are in the form of strips of Wood arranged on edge, and the support for the cushion unit 24, which is of common type as shown in Fig. 2, consists of the cables 25 which are looped over screws 26, their ends being connected by springs/27 to one of the supports.

scribe various modications or adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to `embody or adapt my improvements as may be desired. l

Having thus described my invention what I claim as new and desireto secure by Letters Patent is:

l. In a seat structure, the combination .with front, rear and top support members,

of a cross bar disposed adjacent to said rear support member, coiled spring hangers for said cross bar connected thereto and to said rear support member, a back cushion support connected at its lower end to said cross bar,

coiled spring hangers for said back cushion support connected thereto and to said top support member, a plurality of cushion supporting straps of flexible material, coiled springs connecting the rear ends of said straps to said cross bar and their front ends to said front support member, coiled springs connecting adjacent straps, a seat cushion unit disposed on said straps, said seat .cushion u nit comprising a plurality of body springs connected by al flexible means, and

a back cushion unit disposed above the rear` to said top support member, a plurality ofcushion supporting straps of flexible material, coiled springs connecting the rear ends of said straps to said cross bar and their front ends to said front support member, a seat cushion unit disposed on said straps, said seat. cushion unit -comprising a plu-f Y rality of body springs connected byv a iiex-y ible means, and a back cushion unit disposed above the rear edge of said seat cushion unit and supported by said back cushion support.

3.
