Application led September 28, 1915. Serial No. 53,045.

f1' 'o all whom 'if may concern.'

Be it known that l, GEORGE M. OGLE, a citizen of the United States, and resident of lVakeiield, in the county of Middlesex and State of Massachusetts, have invented certain new and useful improvements in tion, the term car seat is hereinafter used n to designate the entire structure, the term seat portion is used to designate the portion on which the loccupant sits, and the term back is used to designate the backrest. ln a car seat of thetype to which thisv invention'relates, the back is movable from front to rear to enable the occupant to face toward the front or rear of thecar, and the seat portion is so mounted that it will tip toward the back in whichever position of use the back is disposed.l The back, upon being moved to reverse the, facing direction of the seat, assumes in every case a predetermined position or inclination which for convenience is hereinafter designated the normal position or inclination, rbut the back can be adjusted in every case from.

the said normal position or inclination to a reclining position or inclination, regardless of the direction in whichvthe seat faces. The structure which sustains the back in normal position or reclining position is such that if, while the back is in a reclining position it be moved to reverse the facing position ofthe seat, it will automatically resume its normal relation. Consequently, upon the completion of every reversing operation, the back will automatically take its normal position or inclination.

The same reference characters indicate the same parts wherever they occur.

Before describing` the improvements and details which constitute the present invention, l will describe the features of the car seat structurey which are well known.

Referring iirst to Fig. 1,-the floor of the car is indicated at 10. According to this view, the aisle end ofthe seat is at the left and the wall end is at the right. The wall at the right is indicated at 11. ln the present instance, the car seat embodies a duplex construction, by which I mean that it includes two separate and distinct seat portions and two separate and distinct backs. The seat portions and backs are, however,

mounted upon'a single supporting structure,

other. It will be understood, however, that ported by the wall fixture 12, and the other v end is supported by the aisle standard 13, the lattcrhaving two branches 15, 15 for this purpose. in arm-rest is indicated at 1G at the aisle end, and an arm-rest indicated at 17 ilsL arranged substantially midway between the wall 11 and the aisle end.

AThe two seat portions are indicated at 18,

18, and the two backs. are indicated at 19, 19. Y The two seat units are alike in the matter `of structure and arrangement, and a description of the details of one will be sulficient.

Each seat portion is arranged upon a pair of rockers 20, 20, the latter having upwardly projecting dowel pins 21, yand the seat portion having suitable sockets (not shown) to receive them, whereby the seat portion is kept in the desired relation to the rockers. The under surface 22 of each rocker is conveX, for the purpose of causing the seat por-` tion to tip toward the rear with reference t0 the facing direction. upon the two rails 14, 14 and is movable longitudinally thereon Yto cause the tipping movement hereinafter described.

VEachn back 19 is arranged between and supported by two holders 23, 23. 1t is desirable to have the backs,readily'detachable from their holders 23 for cleaning and repairing purposes, and vfor this yreason eachv back is provided with a pair of socket members 19 adapted to sliponto a pair of hold-v ers, the latter' being provided with elongated portions 23 which fit in said sockets. Each back may be detached by simply lifting it...

from the portions 23. This does not aect in any way the adjusting means, hereinafter described, by which the inclination of the seat is varied, such means being separate or remote from the back; Each holder is carried by a pair of arms 24, 25,. The construe# tion of one of these arms is shown by Figs. 5 and 6. The arm includes a sleeve portion v26 and a lower portion 27 at theouter end of which is a boss 28. The two arms 24 are arranged upon and pinned or otherwise affixed to a rockshaft 29, and the two arms .25 are likewise arranged upon and aiiiXed to a rockshaft 30. There are, therefore, two rockshafts and two pairs of arms 24 and 25 for each back 19. The rockshafts for one back are movableindependently of those of the other back.

Eachrocker 20 h as a flange 31 and aflange 32 which coact respectively withthe Each rocker 20 restsV bosses 28 on the lever portions 27 in such manner that as the back is moved to the left from the position shown by Fig. 2 thelever portions .of armsV 24 will move the rockers 2O to the right, vand as the back is moved to f .vided with suitable sockets therefor as shown by Figs. 5 and 7. Each extension carries a pin 35, and the latter is arranged in aslot 3G formed in the arm. The purpose of this pin-and-slot connection is to prevent the ei:- tension from being withdrawn from `its socket, while permitting a limitedrelative movement of the extension member in its socket. Each member 33 is provided with a series of shoulders 37 as the result of forming ratchet teeththereon. A bolt or stop 38 (Fig. 9) is .arranged in a socket 40 inthe arm and is adapted to coact with any one of the shoulders 37 according to the relative position occupied vby the extension members 33. The shoulders and stop member a-re arranged to hold the extension member against outward movement, and-a helical compression spring 41 is .arranged in the socket and.` bears againsta shoulder 42 ofthe stopmem-V ber to keep thel latter in coactive engagement with the extension member as shown byl Figs. 5 and 8. The shank 43 of the stop member projectsbeyond the lever and isv provided with a handle 44 by which it may be retracted to release the extension in ember. Tt is preferable to have the extension member 33 capable of.` being moved inwardly without a special operation for retracting `thevstop member, and for this reason the surface 48. This ear laps the member 33 as shown by Figs. 7 and 8, the fiat surface 48 iet being in contact with the extension member.

The back as shown by Fig.r2 is in its normal position, that is, the position of inclination which it would normally assume in A consequence of being shifted to reverse the facing direction of the seat. The arms 25 are resting upon stops 2. Theseveral eX- tension members 33 are in their respective arms as far as they will go and arevlocked by their respective bolts or stop members. Assuming now that it should be desired to place the back in a reclining position, as shown by Fig. 4, the two handles 44 carried by the arms 24 may be pulled upwardly to release the extension members' 33 of the arms 24. The back is thus released so that it may swing about the pivots 34 of the arms 25, which pivots, it will be observed, are at the rear of the seat. The back may therefore. tilt toward the rear without any appreciable lowering of that portion which sustains the back of the occupan 1f it is desired to have the maximum degree of. inclination, the extension members 33 may be permitted to have the maximum degree of extension movement permitted by the pins 35 and slots36. On the other hand, if it should be desired to sustain the back at an intermediate angle, the extensions 33 may be caught at an intermediate position by the stop members 38 coacting with the intermediate shoulders 37. 1t will be observed that the handles 44 are arranged in a position where they may be easily pulled up by the occupant of the seat.

Assuming now that the back isin a reclining position as shown by Fig. 4 and it is desired to reverse the facing direction of the seat,-the change is effected by moving the back to the left. The first stage of such movement will be simple oscillatory move ment about the pivots 34 of the arms 25 in consequence of which the extension members of the arms 24 will be restored to their normal positions. 1t thus follows that the back will take its normal position whenever the facing direction of the seat is reversed, regardless of whether the starting position of the back is normal or reclining. Continued movement of the back to the left will cause the arms 24 and 25 to swing to the left until the arms 24 engage stops 24. Vhen the back has been shifted to the left the handles 44 of the arms 25 take the same position relatively to the occupant as the handles of the levers 24 have when the back is at the right; and if the back, while at the left, is'released by drawing the handles of the levers 25, the back may tilt about the pivots 34 of the arms 24. Thus when the back is set to face the seat in one direction one pair of pivots 34 provide the axis of reclining movement, and when the back is set to face the seat in the opposite direction the other pair of pivots 34 provide the axis of reclining movement.

Another feature of the present car seat is an improved rest capable of being used either as a foot-rest or as a leg-rest. Each seat unit is provided, in the present instance, with two rests 50, 50. These are alike in all respects and a description of one will be sufficient. The lrest is connected by a pivot member 51 to a curved bar 52. This bar extends loosely through a guide or bearing 53 and is capable of moving longitudinally therein. The lower side of the bar 52 is provided with a series of shoulders 54, the surface running from each of said shoulders to the next being inclined with relation to .the longitude of the bar after the fashion of ratchet teeth. Any one of the shoulders 54 may be engagedwiththe guide at the edge indicated at The two guides 53 for the two rests of one seat unit are, Vin the present instance, formed upon a single' hanger 56., and the latter is supported by .the two rails 14, 14.

In each of Figs! 2 and 4 the rest 50 at the leftisi folded so as to be out of the way and not in position for use. That at the right is in position to serve as a foot-rest for the occupant of the next seat. 1n order to move .the rest from its position of disuse to its position of use, it is first drawn forwardly and upwardly a sufficient distance to carry its rear lower edge beyond the adjacent rail 14. The rest may then be tilted about its pivot 51 to lower its forward edge and raise its rear edge, such tilting movement being limited by the corner 57 (Fig. 2a) of the bar 52.

The rest at the rear of each seat is usable as a foot-rest by the occupant of the seat behind, and at the same time the rest at the front of each seat is capable of being used as a leg rest by the occupant of such seat. The bars 52, being inclined and being capable of considerablelongitudinal upward movement, are capable of supporting the rests at any height which would be required of a leg-rest, and the bars 52 are so curved that the supporting surfaces of the rests approach a horizontal position as the rests are raised.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all the forms in which it may be made or all the modes of its use, what 1 claim is:

1. A car seat structure comprising a seatsupporting frame, a pair of back-supporting members, a pair of oscillatory arms at each side of said frame for carrying said back-supporting members forward and back to reverse the facing direction of the seat, and means forming double connection between each of said back-supporting members and the adjacent pair of said oscillatory arms, to sustain the back-supporting members, said means including double pivotal connection with the back-supporting member and including adjustable elements arranged to vary the angle or inclination of the back-supporting member.

2. A car seat comprising a seat portion, a

lill

means including two pairs of oscillatory arms, slidable members each carried by one of said arms, a pair of back-holders each carried by and pivotally connected to a pair of said slidable members, and connections arranged to hold said slidable members in various positions of adjustment relatively holders 'each pivotally connectedat separate points to a pair of said sliding members, a baclcmounted upon said holders, and 'two pairsl of latching members eachl arranged to cooperate with one of said arms and With one of said sliding members'ito sustain said holders at Various `angular vpositions relatively to said arms.

y In testimony whereof I have ailixed my signature.
