Claims. (Cl. 155--6) This invention relates to reclining chairs for vehicles, and more particularly to a reclining chair and leg rest combination for railway car compartments.

in the development of railway coaches, the recent trend has been towards making use of both the horizontal and vertical space in the car by locating chairs in staggered relation in alternately higher and lower compartments along the car. In this way more leg room, privacy and comfort is provided for the passengers than is available in more conventional coaches in which the chairs are simply arranged one after the other on the same level. However, when the chairs are thus arranged in small compartments, the problem of devising a reclining chair is further complicated by the fact that the back rest of the chair cannot be pivoted to the rear as is conventional Without employing extra space to no advantage. Therefore, it is an object of our invention to provide a reclining chair for a small compartment, of the sort described, in which the chair may be reclined without necessitating extra space to accommodate the reclining motion of the back rest of the chair.

Still another problem presented in the arrangement of these small compartments is the provision of a leg rest for the chair occupant when the chair is reclined. Obviously, if the chair is to be reclined to a substantially horizontal position, some provision must be made forour invention, we provide a chair for a small compart-- ment mounted in a sliding frame in which a back rest and a seat are pivotally mounted. The frame may be moved forward and back by the occupant by releasing a simple catch element followed by applying slight pressure in the desired direction. Then as the frame slides forward, the back rest reclines 'backwardly relative to the frame, but generally follows a downward path relative to the compartment. In this way the necessity for extra space in the compartment to accommodate the reclining motion of the back rest is obviated.

Still another feature of our invention relating to the sliding motion of the frame is that the occupant may position a leg rest in opposed relation and spaced adequately in front of the chair when the chair is in the erect position, thereafter lift his leg and recline the chair by sliding the frame forward to a point at which the seat is in position closely adjacent to the leg rest, and in which the chair is fully reclined. When this is done the occupant of the chair may lie in a nearly horizontal position for sleeping with his legs comfortably supported.

A further feature of our invention lies in the fact that the chair arms and side elements of the chair are carried with the frame as the frame slides forward and the chair reclines. In this way relative motion between the chair arm and side elements is largely obviated and the chair may be reclined without disturbing the occupants clothing or otherwise discomforting him.

An additional feature of our invention relates to the ease of operating the chair frame from its extreme positions of motion. In order to assist the motion of the frame, we provide springs arranged to urge the chair forwardly from its extreme rearward position, and conversely, to urge it rearwardly from its forward position.

These and other objects and features of our invention will best be understood and appreciated from a detailed description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which:

Fig. 1 is a view in side elevation of the chair and leg rest of our invention as shown in a partial section of a small compartment in a modern railway coach;

Fig. 2 is a view in side elevation generally showing the ratchet and pawl arrangement limiting the motion of the chair frame;

Fig. 3 is a view in side elevation showing the general components of the chair of our invention in the fully reclined position with the foot rest likewise in position for use;

Fig. 4 is a view in side elevation of the sliding mechanism upon which the chair frame is mounted;

Fig. 5 is a plan view of the sliding frame mounted on the base with the seat elements of the chair removed; and

Fig. 6 is an end view of the sliding elements of the chair and the base elements substantially as shown in Fig. 5.

The'preferred embodiment of our inventionherein shown includes in its general organization, a chair indicated at 10 and a leg rest indicated at 12 mounted within a railway car compartment having a forward wall 14, a rear wall 16, a forward shelf 18, a rear shelf 20 and a floor 22.

The chair It) comprises a base 24 upon which a frame 26 is slidably mounted. A back rest 28 is pivotally connected to the frame 26 on each side at 30. With reference to Figs. 1 and 3 it will be understood that the support elements illustrated and numbered are only on the near side of the chair. These elements are duplicated on the opposite side, of course, but since they are the same on both sides, only one side will be described herein in detail. The back rest 28 is supported from the rear by means of links 32 which are pivotally connected at 34 to the back rest 28 and at 36 to the chair base 24. It will be noted that the pivotal connection 30 of the back rest 28 is located in the lower part of the said back rest and that the pivotal connection 34 of the link 32 to the back rest 28 is at a high point substantially in the middle of the back rest 28. Thus it will be seen that when the frame 26 slides forward on the base 24, the back rest 28 will recline relative to the frame 26, and simultaneously lower rather than pivoting to the rear in the conventional manner.

A seat 38 is mounted within the frame 26 being supported in its forward portion by links 40 pivotally connected at 42 to the frame 26 and pivotally connected at 44 to the seat 38. The rear portion of the seat 38 is pivotally connected at 46 to depending arms 48 integral with the back rest 28 but extending to a point below the pivot 30 of the back rest 28. Thus it will be seen, particularly with reference to Fig. 3, that the seat 38 will pivot forwardly and upwardly by operation of the links 40 and the arms 48 when the frame 26 slides forwardly on the base 24.

As regards internal con-structiomthe leg rest 12, the

back rest-28 and the seat 38'may'be of conventional frame and upholstered construction as is normally employed in arrangements of this sort.

The frame 26 may be seen more in detail in Figs. 4, and-6 and it comprises generally a base pan SOs-which extends transversely of the chair, being supported at each side by an upstanding bar 52 having a substantially Z- shaped cross section. Eachbar 52-is boltedto a plate 54 which extends downwardly and has an inturned flange 56 at its lower extremity. The flange 56 in turn rides on rollers 58 which are rotatably mounted on an intermediate slideelement60 as may be seen in Fig. 4. Each intermediate slide element 60 has a shallow channel cross section and fits into a' similarly. shapedbut slightly larger opening formed between-an upstanding-anglesection-62 and the outwardly extendingside margins of the base 24. The intermediate slide 60-carries-six different rollers 58 and, these rollers 58 ride on theinner surfaces'of flange 66 of the base angle member 62, and on themargin of the base 24..

Thus it will be seenthat thedepending plates 54 which support the frame 26.ride on the lower rollers 58 and when the frame 26 is withdrawn, the intermediate slide elements 60 travel outwardly approximately. one-half of the distance of the motion of the frame 26. It should also be noted, however, that the two upper rollers 58 of the intermediate slide;6,0 lie-abovezthe flanges56of theplates 54; and by holding the flanges 56 down the upper rollers.58 resist any downward tipping force that might be applied to the outer extremity of the frame 26.

In orderto limit the travel ofthe. frame 26v and also to keep the intermediate slide element.inproper position, weprovide a pair of positioningbolts, 68, secured to the Z-shaped member 52 and operating in a slot 70 on the: base channel62 and in a slot 72 in the intermediate slide 60.- The-slot 70 may serverto limit the travel of the frame 26 at an extreme forward and at an extreme rearward position, and the slot 72 serves-to position the intermediate slide member 60 properly within the moving elements shown.

The frame 26 carries a side arm support 74 on one side thereof and a. back rest pivot support 76 on the other side. It will be understood that the chair described herein with particular reference to Fig. 6, illustrates only one of a pair of such chairsv mounted in tandem relation side by side. Of course,.it would. bepossible to employ an arm rest support 74 on each side of the frame 26 if desired. The back rest support 76 and the arm. rest support 74 serve to mount the pivot of the back rest 28.

In order removably to connect the seat 38 and to support the same in the. forward portion of the frame 26, the links are provided with flanged retaining bolts which drop into slotted holders 78 secured to the Z-shaped members 52 of the frame 26. When the seat38 is in the fully retracted position, it is supported on upstanding cushioned supports 80 mounted on the base pan on either side in the forward portion thereof. Thus it will be seen with reference to Fig. 1 that the cushionedsupports 80 bear the weight of the forward portion of the seat 38 when the links 40 are withdrawn to their extreme rearward position in which their leverage for support is poorest.

In order to hold the chair in a multiplicity of positions of recline, we provide a ratchet and pawl arrangement shown generally in Fig. 2, including a release knob 82 pivoted to the arm rest support 74 and communicating through a linkage system indicated at 84 to a vertically operating pawl 86 carried in the frame 26. The pawl 86 enters appropriately positioned holes 88 in the base 24. With reference to Fig. 5 it' will be seen that five such holes 88 are shown corresponding to five different positions of recline for the chair. It will be understood, however, that other arrangements for limiting the reclining motion of spirit of. our invention.

With reference to Fig. 1, it will be seen that when the chair is erect, the link 40 is in a position whereby the weight of an occupant substantially resists forward motion of the seat 38 relative to the frame 26. Conversely with reference to Fig. 3, it will be seen that when the chair is in the reclined position, the link 32 is in a position in which the weight of the occupant resists returning motion of the frame 26 relative to the base 24. In order to counteract this otherwise disadvantageous arrangement, we provide a pair of forward springs 90 and a pair of rear springs 92 effectively operating between the pan 50 and the base 24. This is accomplished by means of a pair of rods 94 secured to an upstanding flange 96 on the base 24. The rods 94 extend forwardly from the flange 96 and pass through upstanding bar guides 98 mounted on the pan 50. The springs 90 are mounted on the forward ends of the rods 94, being held in that position by retaining nuts 100 threaded to the forward ends of the rods 94. The rear springs 92 are likewise mounted on the rods 94 butadjacent to the rearward ends thereof and abutting the upstanding flange 96 of the base 24. The bar guides 98 compress the springs 90 when the slide 26 is in its extreme forward position, and conversely, they return and compress the springs 92 when the frame 26 is in its extreme rearward position. Thus the springs 90 and 92 aid the motion of the slide from its extreme positions. The distance of the travel of the frame 26 may be regulated by means of a rod 102 secured to the flange 96 and operating through a sliding spool 104 mounted on a bracket 106 secured to the pan 50 of the frame 26. Adjusting bolts 108 may bethreaded to the rod 102 to give varying distances of travel for the frame 26.

It willnow be seen that the operation of the leg rest 12 incooperation with the chair 10 is to swing from a vertical stowed position, as may be seen in Fig. 1, downwardly into arelatively horizontal position for use, as may be seen in Fig. 3. When in the position for use, the occupant of the chair may slide his.chair forwardly substantially to fill the gap between the seat 38 and the leg rest 12 or he may slide the seat back to provide room for standing up between the seat 38 and the leg rest 12. Inasmuch as the base-member 24 of the chair 10 is integrally attached and connected to the compartment elements, it will be seen that the leg rest 12 may be regarded as being pivotally connected to the same base element as is the chair 10.

Since numerous minor variations of our invention will now be apparent to those skilled in the art, it is not our intention to confine the invention to the precise form shown herein, but rather to limit it in terms of the appended claims.
