' To all whom it may concern: 'Be it" known that I, CLARENCE A. VAN

class in which the seat cushionis supported on rockers resting on the seat sills and adapted to be moved back and forth thereon to change the inclination of the cushion when the back is shifted'from one position to another, and in which the back is supported by levers pivotally connected with the seat frame in such manner that the back may be shifted from one side of the seat to the other while being supported by the levers and while being reversed.

The object of my invention is to improve and simplify the construction of car seats of this class, and to provide such seats with a foot-rest mounted in a novel way and so connected with the rockers that when the latter are shifted to chan 'e the inclination of the seat the foot-rest Wlll be moved from one side of the seat to the other so as to always occupy'a position beneath the back.

In carrying out my invention I employ a seat frame of any approved construction and on the sills of the frame I provide rockers to which the seat cushion is attached. The back is supported by levers pivotally connected to the back midway between its upper and lower ends and to the seat frame at opposite ends thereof, in such manner that the back may be reversed and moved from one side of the seat to the other. The levers are provided with laterally projecting studs which engage vertical slots in the rockers s0 that as the back is shifted the rockers are moved to change the inclination of the seat. The foot-rest is suspended from a rock shaft having an arm provided with a lug engaging a slot in one of the rockers, the arrangement being such that'while the back is being reversed and the seat is being shifted a proper movement is given to the foot-rest to shift it from one side of the seat to the other so that it will occupy a position beneath the seat back.

In the accompanying drawings :-Figure 1 shows a side elevation of a car seat embodying my improvements, with parts broken away in order to better illustrate other parts. Fig. 2 shows a vertical section on the line 2-2 of Fig. 3. Fig. 3 shows a vertical section on the line 3-3 of Fig. 2. Fig. 4 is a perspective view of one end of the seat cushion with a rocker thereon. Fig. 5 shows a side elevation of one of the rockers. Fig. 6 is a perspective view of the lower portions of two of the back supportinglevers. Fig. 7 is a perspective View of a portion of the seat frame and a portion of .the foot-rest and its operating mechanism.

The seat frame may be made of any approved construction; preferably it comprises pedestals A connected by sills B of angle-iron which are connected and braced by bridges C. The end plates D have secured to them brackets E to which the sills B are bolted, in the manner shown in Fig. 7. To the end plates D are secured brackets F formed with stops f .for the backsupporting levers and with bosses f for the fixed pivots for the lower ends of the backsupporting levers. The construction at opposite ends of the seat is practically the same.

The back G is of the reversible type. It is supported at each end by two levers H and I,- pivotally connected at their upper ends with the back G midway between its upper and lower edges in the usual way. i

The lower end of each lever H is pivotally connected at h with one of the bosses f of a bracket F and each lever I is pivotally connected at z with another boss f of the adj acent bracket F. By this arrangement the back is supported on either side of the seat and while being reversed, as shown in Figs. 1 and 2. The lever I on each side of the seat is formed with an arm J, provided with a laterally projecting lug j which enters a slot is in the adjacent rocker K. Preferably the two levers I at opposite ends of the seat are constructed in the same Way and made to engage the adjacent rockers. By this arrangement, when the back is moved over fromone side of the seat to the other the rockers are moved on the sills B in such manner as to shift the seat cushion L and This operation is.

change its inclination. similar to that in other seats of this class well known in this art. The movement of the levers H and I is limited by the stops 1 in the manner indicated.

The foot-rest M comprises a cross bar m attached to hangers m secured to a rock shaft N mounted to turn in bearings in the bridges C. One end of the rock shaft is extremely simple, and has been found in practice to be strong, durable and eflicient.

I claim as my invention: A car seat, comprising pedestals, sills conn'ected therewith, end plates connected with the sills, bridges supported on and secured to the sills, a rock-shaft mounted in bearings in the bridges, a foot-rest carried by the rock-shaft, a seat cushion,'rockers supporting the cushion and resting on the sills, an arm on the rock-shaft 'insidethe end plates of the frame and provided with a stud engaging a slot in one of the rockers, a back, back-supporting levers pivotally connected therewith and with the end plates of the frame, and a stud on one of the levers engaging a vertical slot in one of the rockers, and which causes the rockers to shift to change the inclination of the seat and to shift the foot-rest.

In testimony whereof, I have hereunto subscribed my name. 7
