Application August 8, 1945, Serial No. 609,586
The present invention relates to new and useful improvements in reclining chairs adapted for use in railway coaches, buses, airplanes, street cars, automotive vehicles, steamships, as well as for use in homes and other places where a reclining chair is desirable.
An important object of the present invention is to provide pivotally supported back and seat frames by means of which the back may be moved forwardly and rearwardly into a desired inclined position and at the same time the seat is raised or lowered in accordance with the inclination of the back.
A further object of the invention is to provide means for positively securing the back in its inclined position against accidental displacement and in which the adjustments of the back and seat frames are accomplished with a minimum of effort and Without involving the use of complicated mechanism for this purpose.
A still further object is to provide a device of this character of simple and practical construction, which is strong and durable, eflicient and reliable in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, refer ence being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a side elevational view showing the chair in its upright or raised position.
Figure 2 is a similar view showing the back and seat inclined or lowered in its intermediate position.
Figure 3 is a similar view showing the back and seat inclined or lowered into its lowermost reclining position.
Figure 4 is a horizontal sectional view taken substantially on a line 4-4 of Figure 1.
Figure 5 is an enlarged fragmentary sectional view taken substantially on a line 5-5 of Figure 1.
Figure 6 is a bottom plan view of the seat.
Figure 7 is a fragmentary sectional view taken substantially on a line 'l1 of Figure 6.
Figure 8 is an enlarged rear elevational view of the supports for one of the frames.
Figure 9 is a top plan view of the chair.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a U-shaped seat frame and 1 Claim. (Cl. 155-116) the numeral 6 designates a U-shaped back frame.
The ends of the seat frame 5 are pivoted to a pair of brackets 1 by means of bolts or the like 8, the brackets 1 being adapted for attaching to the floor of a railway car or other vehicle or other supporting structure in which the chair is to be mounted in case of home use or other place where a chair may be used. The lower ends of the back frame 6 are similarly pivotally attached to a pair of floor brackets 9 in front of the brackets 1 and adjacent the front end of the seat frame 5.
The sides of the seat frame 5 are formed with longitudinally extending slots I 0 in which the lower ends of the back frame 6 are inserted for sliding movement. The sides of the seat frame 5 are formed with a plurality of longitudinally spaced downwardly extending stops ll adjacent the slots I B, the front edges of the stops being curved, as indicated at i2, while the rear edges of the stops are inclined forwardly, as indicated at 13.
The lower portion of the seat frame 6 is provided with a transversely extending rod I 4 on the ends of which rollers l5 are journaled and adapted for seating against the curved front edges l2 of the stops II to support the back frame 6 in its various rearwardly inclined positions, as illustrated in Figures 1 to 3, inclusive, of the drawings.
A coil spring 16 connects the rod 14 with the front end of the seat frame 5, the spring exerting its influence on the back frame to cause a riding movement of the rollers I5 over the inclined rear edges [3 of the stop and thus pull the back frame 6 into its forward position when the chair is relieved of the weight of a person.
A seat I! includes a frame I 8 to which padding I9 is supported by means of covering or upholstering material 20, as shown in detail in Figure 7 of the drawings, the front edge of the seat I1 resting on the front end of the seat frame 5 and the rear end of the seat being slidably supported on a transversely extending rod 2| carried by the back frame 6, the rod 2! being positioned above the rod l4. To the under side of the seat I! adjacent its front edge is secured a pair of clips 22 adapted for engagement with the front edge of the seat frame 5 to secure the seat against sliding movement on the seat frame and the rear edge of the seat is provided with a pair of downwardly extending stops 23 adapted for engagement by the rod 2| to limit rearward movement of the back frame 6.
The back frame 6 is provided with a back 24 which may be padded and upholstered in the usual manner and one or both sides of the seat I! may also be provided with an upstanding padded or upholstered arm rest 25, that the size, shape and design of the seat, back or arm rests can be so constructed to satisfy the needs for. which the chair is used and the said parts of the chair may be covered with any suitable material as desired.
In the operation of the device, it will be apparent that rearward pressure exerted on the back frame 6 by a person will cause a rearward inclining movement of the back from the position shown in Figure 1 of the drawings to either of the positions shown in Figures 2 and 3 of-the drawings to support the back in a desired inclined position. At the same time, the seat I! is -lowered and slightly inclined rearwardly from the horizontal position, as shown in Figure 1, in accordance with the lowering of the rear supporting rod 2| by the inclining movement of the back.
The back 24 also moves rearwardly of the seat I! to expose a greater portion of the seat area to provide more supporting area for the person when the hair is inclined.
In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in the art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.
Having thus described the invention, what I claim is:
A chair comprising a seat frame of U-form providing sides, rear ends and a front cross bar thereon, the sides being longitudinally slotted, means pivotally supporting the rear ends of said frame for vertical swinging of the frame into different forwardly and upwardly inclined positions, a back frame of the same form as the seat frame and extending crosswise thereof with the lower ends pivotally mounted for swinging of said back frame forwardly and rearwardly and having sides slidably extended through said slots whereby each frame guides the other during swinging thereof, coacting devices on the sides of said frames, respectively, for interlocking to retain the frames in difierently swung positions andsupporting the seat frame on the back frame, a seat vertically swingable at the front thereof on the front cross bar of the seat frame and pivotally and slid'ably supported intermediate the front and rear thereof on the back frame, and spring means connecting said frames and urging the back frame forwardly of the seat frame.
