Specification ofLetters Patent. Patented 1VIa,1'; 15, 1921.

Application'filed September 1, 1920.. Serial No. 407,513.

I all w/lom it may concern Be it known that I, Janus A. Bnoons, a

citizen of the United States, residing in Philadelphia, Pennsylvania, have invented My invention relates to certain improvev ments in car seats, particularly those used for city and suburban service.

One object of the invention is to provide a car seat in which the seat section can be raised. and moved against the back of the seat so as to more readily allow ingress and egress to the space between the seats. A further object of the invention is to so connect the seat section to the frame as to insure the proper positioning of the seat section when shifted from one position to another.

In the accompanying drawings:

Figure l is an end view of a car seat illustrating my invention;

Fig. 2 is a side view;

Fig. 3 is an enlarged sectional view on the line 33, Fig. 2; showing the seat section in its normal position;

Fig. 4t is a similar view showing the seat section raised;

Fig. 5 is a perspective view of the shifting bar and its arms; and

Fig. 6 is a detached perspective View of the stop which limits the movement of the seat.

In the present instance, the invention is illustrated as a wall seat, 1'. 6., one in which there is but a single pedestal at the aisle end of the seat for supporting the seat structure, the inner end of the seat structure being supported on a bracket 2 secured to the frame of the car. as shown clearly in Fig. 2.

The pedestal 1, the seat support 4 and the back support 5 are made in theform of an integral structure, in the present instance. The back 6 is rigidly secured to this structure at the aisle end and to a back support 7 at the wall end. The wall end of the seat section 8 rests on a flange 9 of the bracket 2 secured to the side 3 of the car and at the aisle end this seat section is supported by the end portion 4t of the pedestal structure.

In order to locate the seats as close together as possible, I have found that it is desirable to design the seat structure so that the seat sections can be raised and tilted back against the back section to allow pas seng'ers to pass readily through the space be tween one seat and a seat In frontof it. The

structure for accomplishing this shouldbe such that it can be easily raised andlowered by a passenger.

10 is a longitudinal rod secured to the .ed to brackets ll and 15 respectively, se-

cured to the under side of a car'seat near the rear thereof.

This construction is very simple and when it is desired to raise a seat"fr0m the position shown in Fig. 3, to that shown in Fig. 4:, all

that is necessary is to raise the front edge of V the seat and the arms will holdtheseat in position while being elevated.

In order to prevent the lower edge of the seat moving forward when the seat is elevated, as in Fig. 1, a stop 17 is provided, which may be attached to the wall bracket 2 or to the pedestal 1, as desired. This stop has a projection 18 against which rests one of the arms 12 or 13.

' It will be noticed that the arms connecting the seatsection are limited in their forward movement by the stops, and when the seat .section is lowered they are at such an angle as to insure the seat section assuming a proper position on its support, as gravity due to the weight of the rear of the seat will overcome any friction due to the rubbing of the seat section against the frame at its forward end. Furthermore the rock shaft is so located that the seat section will rest firmly on the frame when lowered. V The arms are so pivoted to the seat section that the inner edge of the section will not rub against the frame in moving from one position to another, and when the seat section is raised it will be supported entirely by the rock shaft and its arms, and when lowered will be supported entirely by the frames; a seat section mounted on the end frames; and arms pivoted to the end frames in front of the seat section, when said seat section israised, and connected to the under side of the seat section, said arms supporting the seat section clear of the frame when raised and preventing the forward move ment of the seat section when said seat section is resting on. the frames.

2. The combination in a car seat, oftwo end frames; a back section connected to the end frames; a rodextending from one end frame to the other; a tube loosely mounted on the rod; arms at each end of the tube; and a seat section. mounted on the frames, the rods beingconnected to the 'under side of'the seat section near the rear, the rod being in such position in respect to the seat section that the arms W111 support the seat section when raised against the back and will holdthe seat section against outward movement when said seat section is resting frames spaced apart, one frame being supported by a pedestal; a backsection securlng the two arms; a seat section mounted 011 the arms; a rod secured to one frame and extending into a bushing in the other frame; a tube mounted on the rod; two arms secured to the tube; brackets on the under side of the seat section to which the arms are pivotally connected, said brackets being located near the rear of the seat section; and a stop to limit the forward movement of the seatsection when the "seat section is raised.
