Patented July 14, 1931 JOHN im non'ron, or Bommr. sramesfimusas COMBINATION BED AND SEAT Application filed December 15, 1928. Serial No. 326,261.

My invention relates to adjustable seats for use on porches, motor vehicles, railway coaches, etc., and the present invention is an improvement on the adjustable seat for which I obtained U. SiLetters Patent No. 1,677,434,

on July 17, 1928.

The main ob-'ect of the present invention is to arrange the metallic strips or ribbons forming important parts of the seat and back,

in such manner that they will be self supporting so that most of the small coil springs shown in the patent above referred to can be dispensed with and thus simplify and reduce the cost of construction.

Another object is to form-the ends of the seats in such manner that when the backs of two adjacent seats are adjusted to a horizontal position to form abed or couch, the end of foremost seat will fit into the end of the rear seat without leaving an open joint between the seats.

A further object is to arrange the metallic strips or ribbons in such manner as to provide a durable, sanitary and comfortable spring mattress.

Other objects will hereinafter appear and in order that the invention may be fully understood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is a sectional view of one of the devices with the-back in raised position in full lines and adjusted to a reclining position in dotted lines.

Fig. 2 is a detail of one. of the metallic strips forming an important feature of the invention. j

Fig. 3 is a longitudinal section of two modified seats arranged in the form of a lounge.

Fig. 4 is a side elevation of a spring mattress made up of metallic strips somewhat similar to those shown by Figs. 3 and 4.

Fig. 5 is a detail perspective view of one of the metallic ribbons employed in the construction of the device disclosed by Fig. 3.

Referring more particularly to the form disclosed by Figs. 1 and 2, 2 in general desig nates the seat and 4 the adjustable back of one of the devices. The seat and the back 2 and 4 include frames 6 and 8, respectively, which are adjustably connected by hinges 10. Means, similar-to that shown in my patent above referred to may be employed for securing the back 4 in different positions.

12 designates one of the metallic strips or ribbons, a number of which are arranged side by side in flie'construction of each device and held in spaced relation to each other by suitable fastening devices 14 and 15. The fastening devices 15 also secure the strips 12 to the frames 6' and 8. The strips 12 are further held in spaced relation by suitable upholstery 16.

The strips 12 are bent in a peculiar manner to render the seat and back portions 2 and c5 4, respectively, of the device resilient, so that they may" accommodate themselves to the shape of aperson sitting or reclining upon the devices; As shown more clearly by Fig.

2 each strip 12 is bent to form an upper portion 18, a convex forward end portion 20, a lower portion 22 which is bent in the form of v a compound curve, a convex end portion 24 and av rear portion 26 paralleling the adjacent part of the portion 18 and terminating in a circular loop 28.

The curved portion 22 extends upwardly from the lower part of the end portion 20 to the upper portion 18 of the strip and thence downwardly in the lower part of which is on a horizontal plane with the lower part of the end portion 20. The upper portion of the segment 30 is secured to the upper portion 18 of the strip by one of the fastening devices 14. Afastcn- 85 ing device 14 isalso employed to secure the circular loop 28 to the adjacent portion 18 of the strip while one of the fastening devices 15 is employed for securing the free end of the loop 28 to the rear portion 26 and the frame 8.

By bending the strips 12 as above described and securing them atcertain points with the fastening devices 14 and 15, said strips 12 are held against extreme forward, backward, or downward movement when subjected tothe weight of a person sitting or reclining upon the device, and by arranging the strips as stated the devices can be read ly adjustedto form a seat or acouch, wlnle'the form of a segment 30, the

compound curved portions 22,.the se ents 30 and the circular loops 28 lend stability to the respective strips 12, and at the same time sistin of a seat frame, a back frame, a plural-' yield sufficiently beneath the weight of the occupant to form a comfortable cushion. The seat portion of each device is also reinforced with an annular spring 32 which is secured to the frame 6 and the portion 18 with fastening devices and 14, respectively.

The form shown by Figs. 3 and 5 issubstantially the same as that disclosed by Figs. 1 and 2, as is evidenced by corresponding reference numerals with exponents a, one difference being that a concave end portion 20a is substituted for the convex portion 20, so

that when two of the devices are arranged in reclining positions as shown by Fig. 3 the convex end 24a of the forward device will fit snugly in the concave end 20a of the rearde- Vice and leave no opening between the two devices.

Coil springs 32a are also substituted for the annular springs 32 and assist in holding the portion 18a in right-angular position when the back is raised to the position shown by Fig. 5.

In Fig. 4'1 have shown the strips 120 employed to form the upper, lower, and end portions ofa box-like spring mattress, said upper and lower portions being spaced apart by annular springs 28c and portions 220 bent in the form of compound curves terminating in segments 3.00. The abutting parts of the mattress are connected together by fastening devices 140.

While I have shown several forms of the I 1 invention I reserve all rights to such other forms and modifications fall within the spirit and tion as claimed.

thereof as properly scope of the invenupper portions of the strips, and an annular spring connected to each strip.

3. A device of the character described conity o flexible strips arranged side by side and suitably secured to said frames, each strip consistin tending over the frames, front and rear end portions joined to said upper portion, a lower portion joined to the front end portion and extending rearwardly in the form of a compound curve, a portion paralleling the upper portion and joined to the rearend portion, said parallel portion terminating in an annular loop, and means connecting the strips to the frames. I

4:. In a device of the character described, a

flexible strip consisting of a long portion, con-- vex and concave end portions joined to said long portion, and a lower curved portion joined to one of the end portions.

5. In a device of the character described, a flexible strip consisting of a long portion, end

of a long upper portion ex-- portions joined to said long Portion, and a lower portion joined to one 0 said end p0r-. tions and arranged in the form of a compound curve.

In testimony whereof I aiiix my signature.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: A

1 A device of the character described consisting of a seat frame, a back frame, and a plurality of flexible strips arranged side by side and suitably secured to said frames, each strip consisting of a long upper portion extending over the frames, front and rear end portions joined to said upper portion, and a lower portion joined to the front end portion and extending rearwardly in the form of a compound curve.
