Patented Jan. 2, 1951 CUSHION CNSTRUCTION Clair S. Reed, Jackson, Mich., assignor to Reynolds Spring Company, Jackson, Mich., a corporation of Delaware Application Alpi-i1 2, 1945, sei-iai No. 586,195

6 Claims.

The present invention relates to improvements in seat cushion construction.

An object of the present invention is to provide a cushion in which resilient material, preferably molded, is combined in a novel manner with coil wire springs.

Another object is to provide an improved seat construction especially designed for automobiles and trucks in which a relatively soft cushion is provided which will not give the impression of hitting bottom when fully depressed as when the vehicle passes over an extremely rough road bed.

A further object is to provide a seat cushion of molded resilient material in combination with encased wire coil springs.

A still further object is to provide a seat cushion having upper and lower portions of molded resilient material with an intermediate section comprising coil springs.

These and other objects and advantages residing in the combination, construction and arrangement of parts more fully appears from a consideration of the following specification and annexed claims.

In the drawing,

Fig. 1 is a cross-sectional view through a seat cushion embodying the present invention,

Fig. 2 is a View similar to Fig. 1 of a modified form of the invention, and

Fig. s is a. View similar to Fig. l1 of stili fur` ther modified form of the invention.

In the form of Fig. 1 is shown a seat construction in having an upper portion i2 of molded resilient materiaL'an intermediate portion consisting of coil springs iii, and alower portion ofy molded resilient material i5 supported upon a suitable base I3.

In Fig. 2, the side and upper portions 25 and 22 respectively are of molded resilient material comprising a pocket 2li in which the coil springs 2t are housed. A lower portion 28 oi molded resilient material is supported on a suitable base 3i! and is connected in any adequate manner to the sides 2i! along the line 32.

The modication shown in Fig. 3 is similar to that of Fig. 2, except the upper molded portion 34 terminates along the line 3d and the molded sides 38 are integral with the molded bottom portion it supported on the base 32.

The molded portions of the several illustrated embodiments of the invention may be of any suitable resilient n oaterial,y such as foam rubber, curled or artificial hair in combination with a suitable binder such as latex, or other similar materials which are resilient, capable of being molded, and will retain their form under use.

Referring to the coil springs lli and 25, these are preferably fabric encased coils of the Marshall type. However, other conventional forms of coil springs may be used, being suitably associated to enable the unit insertion of the same into the molded pocket or between the molded upper and lower portions.

In the form of Fig. 1 the portions l2 and I6 may be provided with fabric covers. Any suitable means may be employed for securely joining the molded portions along the lines 32 and 35.

It should be apparent to those skilled in the manufacture of seat constructions for automobiles, trucks and the like that the illustrated forms will provide a soft cushion, and at the same time, under severe road shock` following maximum absorption by the coil springs, the resiliency of the bottom portions IB, 25 and @il will come into play and avoid the sensation of hitting bottom. Moreover, by controlling the consistency of the molded portions of the construction, structural elements, such as border wires, cross ties, cross wires, helical springs, and other stabilizers and supporting means may be eliminated from or materially reduced in the construction.

Having thus described my invention. what I consider new and wish to cover by Letters lPatent isA as follows: v v .y

' 1, A seat construction comprising a base supporting structure, arr-folded section of resilient material of substantially uniform thickness lia-vingV cushioning properties supportedl on the vbase, anzinterrnediate section comprising coil springs having long springsand shorter snringsarranged to form a unit wedge-shaped in cross section taken from front to back and supported on said molded section with the long springs forwardly, a one-niece upper section of resilient molded material having cushioning properties, said upper section being substantially wedge-shaped in cross section taken from front to back and being disposed and supported on the spring unit with the thickened portion forwardly, and flexible fabric means encasing said springs and holding'r said springs in a pre-stressed condition in the wedge-shaped unitary arrangement.

2.
