CHAIR Filed May 9, 1941 4 Sheets-Sheet l gymww M. K. ORTON Dec. 7, 1943.

CHAIR Filed May 9, 1941 4 Sheets-Sheet 4 Eiwvcnfo'b 17621511" If Or Zon cured to each link 23 and an upholstered seat 2! is supported on the brackets 26 for upwardly tilting movement between each pair of standards iii when the seat and back are in retracted positions and as indicated by dotted lines in Figure 4. The opposite sides of the seat 21 are provided with a laterally projecting lug 40 each of which engages a link 23 when the seat is in its occupied position to prevent the forward end of the seat from dropping downwardly.

The links 23 are each provided with a depending portion adjacent the forward edge of which is an arcuately formed rubber bumper 28 and the upper forward edge of each pair of supporting plates [5, K5 are likewise provided with an arouately formed rubber bumper 29. A strut 3!] secured between the upwardly extending arms v engages the bumpers 28 for limiting the forward movement of the seat 2'! and during normal 00- cupancy of the chair as shown in Figure 3 and the strut 36 engages the bumpers 29 for limiting the rearward movement of the seat when the occupant thereof eifects such movement to permit another to pass before him as shown in Figure 4.

A coiled contraction spring 3| is secured at one end to the tubular strut I! and at its other end to a pin 32 projecting inwardly from the arm 20 for normally maintaining the back 22 and seat 2'! in retracted position as best shown in Figure 4.

Each of the several pivotally connected members such as the links 23, 24 are here shown as connected by bolts 33, fibre washers 34, 35 and the fibre washer 36 within the cup 31 being preferably used to prevent noise.

Since each link 23 is disposed substantially horizontally in its pivotally connected relation to the seat supporting brackets 26 and since each link is slightly swingable forwardly-rearwardly about its lower pivotal connection, all as best shown in Figures 3 and 4, the seat 21 and back 22 are each forwardly-rearwardly movable to provide ready and convenient egress from and ingress to unoccupied seats in the same row without seriously disturbing the occupant of such a chair or the occupant of a chair immediately rearwardly of such occupied chair.

It will thus be seen that the chair herein shown and described is comfortable in use, is relatively simple in mechanical construction and is reasonably economical in manufacture, and while but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.

I claim:

1. A chair comprising a pair of spaced vertically disposed standards; a chair back interposed between the standards the opposite sides of which back are each provided with a forwardly extend ing portion; a vertically disposed plate secured to the inner side of each standard in spaced relation thereto; a pair of upwardly extending arms, each pivotally connected at its lower end adjacent the forward end of one of said plates and each pivotally connected at its upper end to one of said forwardly extending portions of thechair back; a pair of upwardly extending links disposed rearwardly of the upwardly extending arms, each pivotally connected at its lower and adjacent the rearward end of one of said plates and each pivotally connected at its upper end. to

one of said portions of the chair back; pairs of toggle links, each pair having one of its links pivotally connected to one side of the chair back and each having its other link pivotally connected to an upwardly extending arm; a seat secured at its opposite sides between like links of each pair of toggle links; and means for maintaining the seat in a substantially horizontal position when occupied.

2. A chair comprising a pair of spaced vertically disposed standards; a chair back interposed between the standards the opposite sides of which back are each provided with a forwardly extending portion; a vertically disposed plate secured to the inner side of each standard in spaced relation thereto; a pair of upwardly extending arms, each disposed between one of said plates and its adjacent standard and each pivotally connected at its lower end adjacent the forward end of one of said plates and each pivotally connected at its upper end to one of said forwardly extending portions of the chair back; a pair of upwardly extending links disposed rearwardly of the upwardly extending arms, each pivotally connected at its lower end adjacent the rearward end of one of said plates and each pivotally connected at its upper end to one of said portions of the chair back; pairs of toggle links each pair having one of its links pivotally connected to one side of the chair back and each having its other link pivotally connected to an upwardly extending arm; a seat secured at its opposite sides between like links of each pair of toggle links; and means for maintaining the seat in a substantially horizontal position when occupied.

3. A chair comprising a pair of spaced vertically disposed standards; a chair back interposed between the standards the opposite sides of which back are each provided with a forwardly extending portion; a vertically disposed plate secured to the inner side of each standard in spaced relation thereto; a pair of upwardly extending arms, each pivotally connected at its lower end adjacent the forward end of one of said plates and each pivotally connected at its upper end to arms, each pivotally connected at its lower end I adjacent the rearward end of one of said plates and each pivotally connected at its upper end to one of said portions of the chair back; pairs of toggle'links, each pair having one of its links pivotally connected to one side of the chair back and each having its other link pivotally connected to an upwardly extending arm; a seat secured at its opposite sides between like links of each pair of toggle links; a strut interposed and secured between the vertically disposed plates; and means for maintaining th seat in a substantially horizontal position when occupied.

4. A chair comprising a pair of spaced vertically disposed standards; a chair back interposed between the standards the opposite sides of which back are each provided with a forwardly extending portion; a vertically disposed plate secured to the inner sideof each standard in spaced relation thereto; a pair of-upwardly.

at its lower end adjacent the rearward end of one of said plates and each pivotally connected at its upper end to one of said portions of the chair back; pairs of toggle links, each pair having one of its links pivotally connected to one side of the chair back ,and each having its other link pivotally connected to an upwardly extending arm; a seat secured at its opposite sides between like links of each pair of toggle links; a stop secured to a like link of each pair of toggle links; a stop on each plate; an equalizing strut interposed and secured between the upwardly extending arms adapted to engage the link stops during a forward movement of the seat and adapted to engage the plate stops during a rearward movement of the seat; and means for maintaining the seat in a substantially horizontal position when occupied.

5. A chair comprising a pair of spaced vertically disposed standards; a chair back interposed between the standards the opposite sides of which back are each provided with a forwardly extending portion; a vertically disposed plate secured to the inner side of each standard in spaced relation thereto; a pair of upwardly extending arms, each pivotally connected at its lower end adjacent the forward end of one of said plates and each pivotally connected at its upper end to one of said forwardly extending portions of the chair back; a pair of upwardly extending links disposed rearwardly of the up wardly extending arms, each pivotally connected at its lower end adjacent the rearward end of one of said plates and'each pivotally connected at its upper end to one of said portions of the chair back; pairs of toggle links, each pair having one of its links pivotally connected to one side of the chair back and each having its other link pivotally connected to an upwardly extending arm; a seat secured at its opposite sides between like links of each pair of toggle links; a stop secured to a like link of each pair of toggle links; an equalizing strut interposed and secured between a pair of like movable links adapted for engagement with said stops for limiting the forward movement of the seat in its normal position of occupancy; and means for maintaining th seat in a substantially horizontal position when occupied.
