Abstract: 617,767. Seats. BUDD CO. Nov. 8, 1946, Nos. 33229 and 33230. Convention date, Nov. 27, 1945. [Class 52 (ii)] A seat for a railway car or the like, arranged as one of a row of seats one behind the other comprises a seat support, cushion, seat back and leg and foot rests movable from inoperative to operative position in which the foot rest is disposed below the seat of the row in front the underside of the seat cushion and its support being tapered towards the rear upper margins thereof so as to increase foot room and permit closer spacing between the rows. Vehicle seats are provided with angularly adjustable backs and leg rests the latter of which have extensible foot rests the seats being arranged in rows one behind the other and in order to permit adequate foot and leg room the seat 124 and back 13, Fig. 9, haveouter faces tapered towards the pivoted junction. Fig. 3 shows the operating mechanism mounted in each seat arm whereby the back and the leg rest can be adjusted in angular position. The back 13 is pivoted at 24 which carries at each side an arm 48 having at its remote end a sleeve 50 through which passes a rod 51 pivoted to the frame at 52 and surrounded by a compression spring 53 tending to raise the back 13. Fixed on the arm 48 is a sleeve provided with a tooth 49 adapted to engage any one of a series of notches 41 on a pivoted quadrant 40 connected by a link 43 with a pivoted bell crank 44 which is operable by the seat occupant to draw the quadrant 40 away from the tooth 49 allowing the back to rise to its new desired position where it is locked by releasing the quadrant 40 and allowing its spring 42 to draw it into engagement with the tooth 49. The leg rest 14 is pivoted on a shaft 66 carrying at each side a collar 68 having a central circumferential groove within which a link 71 is pivoted. This link and a link 75 are connected to a tubular shaft 80 having a compression spring 72 whereby the leg rest tends to rise. The collar 68 is provided on each of its rims with notches 70, displaced angularly with respect to one another the notches 70 being engageable by a tooth 81 arranged on each of two independent levers 82. A finger button 85 by pressing on the appropriate lever 82 releases the tooth engaging a notch and permits the leg rest to rise into its new position where it is locked by allowing one of the teeth 81 to re-engage a notch 70. The leg rest is provided with an extensible foot rest 15 which comprises channel members bolted to the cross piece 89, Fig. 5, against which the occupants' feet rest. The foot rest is provided at each side with a rack 101 engageable by a pinion 104 biased by a torsion spring to tend to extend the foot rest. A pawl 108, urged by a torsion spring, engages the teeth of the rack and locks the foot rest in desired position. A finger piece 115 connected to the pawl 108 is provided to release it from the rack and allow the foot rest to move to a new position. The leg rest and the seat are preferably arranged at their junction so as to render their covering fabric almost continuous in all positions of adjustment.
