2 Claims.

The present invention relates to seat structures and more particularly to seats which are especially well adapted for installation in buses, airplanes, motor cars and railway coaches.

The primary objects of the instant invention are to provide a structure of the character above indicated which is light in weight, sturdy in construction and yet economical in manufacture and attractive in appearance; to provide such a seat structure which is comfortable in use; to provide such a structure which is free of projections to catch or tear the clothing of persons occupying or moving to or from the seats; and further, to provide such a seat which may be readily and conveniently constructed and assembled.

An illustrative embodiment of the invention is shown in the accompanying drawing, wherein:

Figure 1 is a side elevational view of a seat structure of the character hereinbefore set forth;

Figure 2 is a rear elevational View thereof;

Figure 3 is an enlarged fragmentary perspective view of the back, bottom, and a side of the structure; and

Figure 4 is an enlarged sectional View thereof on line 4-4 of Figure 1.

Referring then to this drawing in which like parts of the seat structure shown are designated by the same numerals in the several views, the structure comprises front legs I and rear legs I I, preferably formed of tubular metal stock. Each front leg and each rear leg is secured together by a brace I3 likewise preferably formed of tubular metal stock.

Each rear leg of the structure has a flattened upper portion I4 to which is secured as by bolts or rivets I5 a back plate I6 of sheet metal stock. The back plate is provided along its bottom edge with a forwardly extending flange I1 which is preferably strengthened by inwardly extending brackets I8 having forwardly extending top flanges 34 secured as by spot welding to the flange Il, and forwardly extending si-de flanges 35 secured as by spot welding to the rear legs of the seat structure.

A supporting frame is here shown as formed of a continuous tube of metal stock having a front portion I9 secured to the upper flattened ends 2l] of the front legs as by bolts or rivets 2|, side portions 22 disposed outwardly from the front legs an-d which extend rearwardly-upwardly, and a top rail 23 between the rounded corners 24 of the frame.

The upwardly extending segments 25 of the side portions 22 of the supporting frame are provided with flanges 26, 2'I struck out of the tubular metal stock and the back plate I6 is secured thereto in any convenient manner as by bolts or rivets 28.

A seat plate 29 is supported at its front edge by the front portion I9 of the supporting frame to which it is secured and the rear edge of the seat plate is secured to the upper surface of the forwardly extending flange I'I of the back plate I6 as by spot welding.

Suitably upholstered spring cushions 30 may be secured to the seat plate 29 in any convenient manner and a similar cushion 3| secured to the back plate I6. The seat plate may further be provided with a reinforcing angle iron 32 and with vents 33 for the escape and admission of air to the compressible spring chamber of the seat cushion.

It will thus be seen that the angular segments 22 of the side portions of the supporting frame are so associated with the seat plate 29, the back plate I6 and 'their connecting flange I1, that a rugged and sturdy construction is provided at the angle where seat and back meet. An economical and attractive seat is thus provided by the use of a continuous metal tubing extending around the seat and the back which serves as a supporting frame for the structure.

While but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.

I claim:

l. In a seat structure of the class described, front and rear pairs of legs, an upstanding back plate secured to said rear legs and having a forwardly extending bottom flange, a supporting frame having a front portion secured to said front legs, side portions extending substantially horizontally rearwardly from said front portion and then angularly rearwardly-upwardly and finally upwardly adjacent the sides of said back plate and secured thereto, and a top portion adjacent the top of said back plate, and a seat plate supported by the front portion of said supporting frame and supported bythe bottom flange of said back plate.

2. In a seat structure of the class described, front and rear pairs of legs, an upstanding back plate secured to said rear legs and having a forwardly extending bottom flange, a supporting frame comprising a continuous tube secured to 'said front legs and extending across the front of the structure and rearwardly at opposite sides thereof and thence angularly rearwardlyupwardly then upwardly adjacent the sides of said back plate; and finally across the top of said back plate, means for securing said frame tosaid back plate, and a seat plate supported by the front portion of said supporting frame and supported by the bottom flange of said back plate.
