Referring now to Figs. 1 "and 2, 20 generally indicates the support" of a an" adjustable reclining armchair. Saidsupport 20 comprises "theside .walls 22 and -24 connected with each other-by the rear wall '25 and-a pair--of-cross-bars 28. The arm-rests of the chair-are inclu'deddnthe side Walls thereof. A'back-rest including -a "downward. extension 32' isnswing'ably mounted on the support 2!! at 34. "The rear end of a seal-. 36 is swingably-mounted on the support--.at 34 in coaxial alignment with the pivotal connection .betweenthe back;-rest--30and the support 20.

The upperend of' atcurvedfront connecting 'link 38 is pivoted to the frontaend :of the seat 5 36- at 40. A lowerconnecting-link! ispivotedto the said front connecting-link}?at .4'4. ;The-rear' end portion of :saidlower'rconnecting linki42' 'is pivotedto the downward extension 32 of the back-rest 30 at 146. The-lower end of a'guiding link 48 is pivoted :to...the -.lower--connecting.. link '42. at 50; the "upper end'iof-zs'aidiguiding; link 48 is pivoted to the-support 0.:at952.

Thus, .theconstrained linkage of .atherchair shown in Fig. 1 includesJthe portion lOf .the support between. the pivots, 34 and 52 a'siitsstationary link and the downward extension 32:..ofthebackrest-structure, the lower connecting .link .42, the

front connecting link :38, the seatLSB land the guiding link 48 as i-itsimovable'jlinks.

"According to the; invention :the :upper end of a leg-rest 54 islpivoted at;56 atoa forward-extension 58 of the lower-connecting link 42. --'According to the embodiment shownin Fig. lsaidforward extensiontB is integral'awith the lowen'connecting link 42, however,.-if: desired; this member 58 could be rigidly: connected with the lower-con necting link-.42inaa different way, for exampleby means of screws. .The front connecting link. has a downward extension...60.projectingbeyond the pivotal connection.44.of thelfrontconne'cting link 38 with the lowerconnecting. link 42. "According to the exhbo'climentshown in Fig.',1" this downward extension 60- is 'integral withthefront connecting link 38 howeven'ifdesiredtthe-mem= ber 66 can be rigidly connected with the front connecting link 38 in a different way, for example by screws or the like. The rear end of a controlling link 62 is pivoted to said downward extension 60 of the front connecting link 38 at 64. The front end of said controlling link 62 is pivoted to the leg-rest 54 at 66.

The lower connecting link 42 with its forward extension 53 and the front connecting link 38 with its downward extension 63 form a scissorlike device, the pivotal connection 44 oi which is oiiset rearwardly relative to the pivotal connection 46 between the front connecting link and the seat 36. The pivotal connection 46 between the front connecting link 38 and the seat 36 is arranged near the front end of the latter and the pivotal connection 56 between the forward extension 58 of the lower connecting link 42 and the leg-rest 54 is located near to the lower edge of the seat 36.

Thus, when the movable back-rest 33 and seat 36 of the chair shown in Fig. 1 are brought into a reclined position as shown in Fig. 2, the legrest control arrangement connected with the link system of the chair causes a lifting of the leg rest 54 into the elevated position shown in said Fig. 2,- at the same time, owing to the

scissorlike device

36, 66 and 58, 42 included in said leg-rest control arrangement, the distance between the

pivots

46 and 56 is increased, so that the leg-rest 54 is advanced to such an extent, that it may properly support the legs of a tall person.

According to the embodiment shown in Figs. 3 and 4, the leg-rest control arrangement includes a separate mechanism pivotally connected with links of the constrained linkage of the cl According to Figs. 3 and 4, the back-rest 53?! having a downward extension 532 is pivotally connected with the support 123 at Hit. The rear end of the seat E36 is pivotally connected with the support 426 at I35. The lower connecting link M3 pivoted at its rear end with the down ward extension 32 at !46 is pivotally connected with the lower end of the front connecting link I39 at [43. The upper end of said front connecting link E39 is pivoted at l4| to the seat A guiding link H43 pivoted at its upp r end to the support 225 at 552 is pivotally connected with the lower connecting link I43 at I56. guiding link I48 includes an extension 43 projecting downwardly beyond the pivotal connection The scissorlike device of the leg-rest control according to said embodiment of said Figs. 3 and 4 includes two double-armed levers 63 and pivotally connected with each other at M4. The upper arm i323 of the double-armed lever 1263 is pivoted to the front end of the seat 536 at 44. The lower arm i653 of said double-armed lever IE8 is pivoted to the rear end of the cont; inng link 462 at M4. The front end of said controlling link l62 is pivoted to the leg rest E54 at i66. The forwardly extending arm 156 of the doublearmed lever H6 is pivoted to the upper portion of the leg-rest H54 at i56. The other arm M2 of said double-armed lever Elli is pivotally con nected with the downward extension I49 of the guiding link 548 at H2. Again, the pivot 544 between the elements i66 and 576 of the scissor-like device of the leg-rest control arrangement is rearwardly offset relative to the pivotal connection I46 between the upper end of the doublearmed lever I66 and the seat Hi6; furthermore, the pivotal connection (56 between the leg-rest I54 and the forwardly extending arm 8 56 of the double-armed lever H0 is located below and near to the lower surface of the seat I36.

When the movable members of the chair are brought into the reclined position shown in Fig. l, the leg-rest I54 is lifted and advanced into the position shown in said Fig. 4.

According to the embodiment shown in Figs. 5 and 6, the separate leg-

rest control arrangement

268, 216, 262, 254, corresponding to the separate leg-rest control arrangement described above in connection with Figs. 3 and 4 is pivotally connected at 212 with a downward extension 243 of a guiding link 248 pivoted to a lug of the support 220 at 252. The guiding link 243 is integral with an intermediate connecting link 214 of a chain of connecting links including the front connecting link 276, said intermediate connecting link and a top connecting link or arm-rest 278.
