RESILIENT SUPRT FR CUSHION SEATS.

n Application filed December 22, 1926. Serial No. 156,491.

rlllhis invention relates to resilient supports for cushion seats, and has particular' refer ence to a resilient-support for cushioned vehicle seats, the same being in the nature of an improvement upon prior United States May 11, 1926.v

ln constructing supports of this Character' l especially for vehicle seats, it has been noted where the seat vis of a width to accomodate more than one person, the employment of a singleL resiliently mounted frame is of a disadvantage in view of the fact that where one person sits ononexside of the seat or where persons of extremely different weights sit up on opposite sides of the seat, the single supporting frame has a tendency to become canted rendering the seat uncomfortable, strain ing the structure, and generally detracting from the efficiency thereof.

ln order to overcome the above-recited objections and to materially add to the general eliiciency of the structure, the present invenf` tion comprehends a resilient support for cushion seats which includes a stationary frame and a plurality of independently movable resiliently mounted cushion supporting elements which serve to closely conform to localized weights imposed thereon, thereby rendering the seat more` comfortable to the users.

Other objects reside in the features of r simplicity, rigidity and strength of construc- 0 tion and the economy with which the same may be produced.

TWith the above recited and other objects in view, reference is had to the following specification and accompanying drawings in which there is exhibited one example or embodiment of the invention which is'in no way intended as a limitation upon the scope of the appended claims as it is to be clearly understood that variations and modifications which properly fall within the scope of said claims may be resorted. to when found keX- pe'dient.

ln the drawings- Figure. 1 is a plan view of the seat support;

Fig. 2 is a longitudinal sectional view therethrough taken approximately on the line indicated at v2--2 in Fig. 1;

Fig. 3 is a transverse sectional view taken Letters Patents Nos. 1,021,949 and 1,584,517, granted, respectively, on May 28, 1912, and` AReferring to the 'drawings by charactersr of reference, the seat support includes substantially rectangular 'upper and lower frames 10 and 11, whichare connected by vertical or upright corner and intermediate members 12 and 13. Adjacent' the upper front portion of the framework a transversef bearing rod 14 is mounted, to which is pivoted in longitudinally spaced relation, elements in the nature of flexible resilient straps is a fragmentary sectional View` 15, which are preferablyfconstructed of sheet metal bent at a point substantiallyv intermediate the ends to provide a knuckle or sleeve 1G embracing the bearingrod 14. The remaining portions or leaves are bolted', riveted, or otherwise secured together at 17, with the free rear terminals .18 and 19 slightly offset to receive and clampy therebetween a` continuous flexible transverse strip 2O of leather or other suitable material which allows for a limited relative independent vertical movement of the free rear ends of the elements 15. The extremities of the terminals 18 of each element 15, are turned up as at 21,

and areapertured to receive the lowerends or convolutions 22 of coiled contractile n springs 23, theupper ends or convolutions 24 of which are suitably anchored to the upper frame member 10, whereby the rear free ends of the elements 15 are normally supported by the springs 28 and tensioned against downward movement. The elements 15 are normally disposed ata rearward and downward inclination and are adapted to receive thereupon a cushion seat A. In order to prevent rearward gravitation ofthe seat A, the upper leaf of each element 15 adjacent its rear end, is formed with an upwardly offset portion 25 which is preferably formed integral therewith to provide an abutment or stop against which the rear end B kof the cushion seat abuts. The forward end C of the cushion seat A is adapted to directly rest upon the upper frame member 10, and a depending flap or apron D is carried by the forward end C to overlie and conceal the stationary frame of the support. In order to space and prevent lateral shifting movement of the fulcruniied forward ends of the elements or straps 15, the upper frame l() may have bolted or otherwise secured thereto spacing devices 2G which also serve to support the bearing rod '14.

In use, it is obvious that a wcightvimposed upon the cushion seat A will effectdownward movement only of the number of elements or straps l5 over which the weight is imposed with .only a slight movement of the adjacent elements l5 on opposite sides by the fiexible connecting strip 20. The elements l5 in addition to moving` rbodily down under the weigh-t and absorbing the shoclrs and ars incident to travel over t-he road, are also capable of` a slight flexing or bowing to augment the function of the springs 23.

/Vhat is claimed is:

l. A resilient support for cushion seats, including a 5stationary frame, a plurality of independently relatively movable cushionsupporting elements resiliently mounted in the frame at one of their ends, means for tensioning the same against downward movement at their opposite ends and for normally retaining said ends elevated, and a flexible connection between the latter ends for limiting the relative movement between the elements. i

2. A resilient support for cushion seats, including a stationary frame, a plurality of resilient cushion-supporting elements, means for independently fulcruming the forward arf/'01,2331

ends of the elements to the upward forward portion of the frame, contractile means of connection between the rear ends and the upper rear portion of the supporting frame for tensioning the same against downward movementA and normally retaining the same elevated, said elements consisting of a length of resilient material bent at a point substantially intermediate the ends to provide a sleeve, the remaining portions constituting leaves, securing means attaching the leaves together, and a flexible connecting means between the rear ends of the elements to permit of relative limited independent movement.

3. A resilient support for cushion seats, including a stationary frame7 a plurality of resilient cushion-supportin'g elements, means for independently fulcruming the forward ends of the elements to the upward forward n portion of the frame, contractile means of connection between the rear ends and the upper rear portion of the supporting frame for tensioning the same against downward movement and normally retaining the same elevated, said elements consisting of a length of resilient material bent at a point substantially intermediate the ends to provide a sleeve7 the remaining portions constituting leaves, securing means attaching the leaves together, and a i'iexible connecting means between the rear ends ef the elements to permit of relative limited independent movement, the rear ends of the leaves having clamping engagement therewith.
