Referring, nowto Figs, 1 and: 2,. l0 generally indicates a support in the shape of a casing, which may be of any suitable; material, such wood, metal plastic-or the like.

The rear end portion of a seat 28 is pivoted to the support I8 at l5. On each side of the chair, the upper end portion of a front link 30 is pivoted to the seat 28 at 32. The lower end portion of said front link 30 is pivotally connected at 34 with the lower portion of a connecting link l8, the upper portion of which is pivoted at 28 to the support I!) at a point spaced from the pivotal connection between the seat 28 and the support l8. Thus, the seat 28, the front link 30, the connecting link l8 and the stationary portion of the support I 8 between the pivotal shown in Fig. 1, the sitting position of the movconnection 28 of the connecting link l8 with the v A support It] and the pivotal connection of the seat 28 with the support l8 form the links of a four-bar link mechanism.

A back-rest i2 is pivoted to the support l8 at M at a point spaced from the pivotal connection l5 of the seat 28 with the support l8. Said backrest I2 has a downward extension I6 projecting beyond the pivotal connection I 4 of the back-rest l2 with thesupport. According to Fig. l said downward extension 13 is integral with *said back-rest l2; if desired, however, said downward extension 16 and said back-rest I2 may be made of separate pieces rigidly connected with each other in any suitable manner. On each side of the chair the rear end portion of a lower link 22 is pivoted to the downward extension iii of the back-rest H2 at 26 at a point below the pivotal connection I4 between the back-rest l2 and the support I8. The front end portion of each lower connecting link 22 is pivoted at 24 to an extension 62 of the connecting link 18 projecting beyond the pivotal connection 34 of the connecting link It; with the front link 38. I

As will be apparent from above, the seat 28 and the downward extension N5 of the back-rest I2jform movable links of a polygonal compound h linkage comprising the

movable links

28, 38, [8-32, 22, IE and the stationary links represented by the stationary portion of the support In between the pivots l4 and l5 and the stationary portion of the support 18 between the pivots I5 and 28' When the user of the chair leans the weight of his body against the backrest [2 for moving same from its sitting position shown in full lines into the reclined position shown in dash and dot lines, the front link 38 pivotally connected with the connecting link l 8--62, which in turn is connected with the downward extension I 6 of the back-rest l2 through the medium of the lower link 22, controls the movements of the seat 28, so that the latter is brought'from its sitting position shown in full lines into its reclined position shown in dash and dot lines. During said movement of the members of the chair from the sitting position into the reclined position, the angle between the backrest l2 and the seat 28 is increased;

As will'be readily understood, the degree of lifting the seat 28 depends on the length of the front link 30 and its connections with the connecting link l8 and the seat 28. 'For example, if the front link 38 were of shorter length and were connected with the connecting link l8 at a point above the pivot 34, the seat 28 would be lifted to a lesser degree when the proportions of above mentioned polygonal compound linkage remain unchanged and the back-rest I2 is brought into the extreme reclined position shown in Fig. 1. In other words, owing to above described control of the seat 28 by the front link 30 pivoted to the connecting link 18, the designer of the chair has a wide rangefor'obt'air'ling dif- 1 able members of the chair is limited by the wall 36 of the recess 38 of the support l8 receiving the seat 28 in its sitting position. The extreme reclined position of the movable members of the chair is limited by the inclined wall 43 of the support In cooperating with the back-rest I2.

' support I 3.

On each side of the chair an arm rest 42 is rigidly secured to the back-rest l2 by screws 44 or the like. r

A locking device generally indicated by 48 may be used for holding the movable members of the chair in any desired adjusted position. Ac-

cording to Figs. 1 and 2 said locking device 46 comprises a bar 48 swingably mounted on a frame member of the seat 28 at 50. Said bar 48 has a slot 52 for slidable engagement with a bolt 54'having a square portion 58 inserted into a corresponding square aperture of the support 13. The bolt 54 has on one of its ends a head 58 for engagement with a surface of the bar. A locking knob 68 is screwed onto the opposite threaded end of the bolt 54 projecting from the If the locking knob 68 is loosened the bar 48 may be freely moved, so that the seat 28 and the other movable members of the chair connected with the seat may be brought into any desired position. If, however, the locking knob 63 is tightened, so that it clamps the bar 48 by means of the head 58 and the bolt 54 against the support [8, the seat and the movable members of the chair connected therewith are firmly held in their position.

Fig. 3 illustrates another embodiment of an adjustable reclining chair according to the invention. The rear end portion of the seat 328 is swingably mounted on the casing-like support 3l0 at 315. The upper end of a front link 330 is pivoted to said seat 328 at 332. The lower end of said front link 338 is pivoted at 334 to the lower end of a connecting link 3l8, the upper end of which is swingably mounted on the support 3H) at 320. a

A back-rest 3i2 having a downward extension 316 is swingably mounted on the support 3l8 at 314 at a point spaced from the pivotal connection 3|5 between the seat 328 and the support 3l8.

The rear end portion of a lower link 322 is pivoted to said extension 316 of the back-rest 3E2 at 326. The front end portion of said lower link 322 is pivotally. connected at 324 with the connecting link 3l8 at an intermediate point thereof between its

pivotal connections

328 and 334 with the support 3l8 and the front link 330 respectively.

An arm rest 342 is rigidly secured to the backrest 3|2 at 344.

The sitting position of the movable members of the chair limited. by the wall 336 is shown in full lines, while the extreme reclined position of the movable members limited by the abutting wall 340 is shown in dash and dot lines.

The movable members of the chair may be held assume! .in any .desired position :by.means oi the docking device 346.

Thetmechanismof therecliningtchairtshown in A is similar to .the mechanism'of thepchair shown in Fig. l. .The chaireshown inFig. .4-,however, is provided with means whereby the eficctive length .of the lower .link 422, the connecting link 4l8-and the seat 428 may .be varied and adjusted as will .be described hereinafter. Theseat-428 swingably mounted on the support -4 Iii-at 415 has aseries of holes 41-4. A pin 432 passing through a bore of the front link 430 may baselectively engaged with one hole'of-said series of holes 414. :Likewise, :the connecting link 4L8 swingably .mounted on the support at 420 is providedwitha seriesof holes 412 .forselective engagement with again-434 passing through abore of the lowerzend of. the front link 4311.

. The downward extension .4; of .theback-Prest M2 .swingably mounted on :the support M is provided with a .first series of .holes 468 a second series of holes 468. A pin-426 :passing through a bore'of the lower link --422.may beselectively engaged-withone holeof theseries ofholes 466. The front end portionofthelower link 42.2 isprovided with a series of holes 410. A pin 424 passing throughabore-of .the extension 1462 of the connecting link 4l8.may be selectively engaged withone hole of the series of holes .410 ofthe lower-link 422.

A leg-rest 416 swingablyrmounted on the front portion of the seat428-at 418 .is provided with-a series of holes480. Oneend of a-controlling link 482 is provided with a .seriesof holes .484; said endof the controlling link 4'82 is pivotally connected with the leg-rest 416 byimeans of a pin 486 inserted .into one holeof the-seriesof holes 484andinto a hole of -the series of holes 480. In a similar manner the-other endof theeontrolling link 482 vhaving a series of holes 488 is pivotally connected with the downward extension "4l6 of the back-rest M2 by means of a pin 480 fitting into one of the holes 468. As will-be readily-understood, the selective engagement of the pins 485 and 498 witha holeof the series of

holes

484 and 488 of thecontrolling :link 48 2ipermits a variation of the efiective-lengthlof the latter.

. 492 indicates aside wall of the support MB. :A substantial portion of said side wall 492 is "de- .tachably mounted .inthe casing :forming the 'support M0 by means of screws 494, so that theuser of the'chairmay have accesstothe mechanismof the chair after removal of .said covering side wall 432 for a purpose .to be described. hereinafter. 485 indicates an aperture of the casing 4 to for the passage of the controlling link .482.

The sitting position of the .movablemembers of the chair is limited'iby ars'topJB'B arranged .on the support 4H] for cooperation with the seat 428, and the extreme reclined position of the movable members of the chair jislimited by the inclined wall 440 cooperating with the back-rest.

The adjustable reclining chairs'hown in Fig. .4 is equipped with a first locking device generally indicated by 446 and a second locking device generally indicated by 49.8. Both locking devices are of the type shown in "Fig. '2 and described above in connection withthe 'chairis'hown'in Fig. 1. The locking bar 448 of the first locking device 446is swing'ably mounted on the seat 428 at 58, .so that said locking device" 446 'is associated with the seat and the support. The locking bar 491 of the second locking device 498 is swingably mounted on the .connectinglink M8 at 489, so .lthatthe second locking device 488 isassociated 1:6 with said aconnecting link :418 and zthe support 418. :If the movable membersof the chair are :connected with :each other as :shown in Fig. 4, they may he .heldiin any desired adjusted jposition .by tightening :eitherone of the locking devices 446.01'488.

.=If the user ofthe-ehair wishes to have the backrestat adifierent angle relative to the seatwhen the latter is in a certain position, "he mayhold the seat in' said certain position by a tightening 'of' the locking device 446. The other locking device 498 remains in loose condition. Now, the userof the chair may changethezposition of the pivotal connection-426betweenthe lower link 422 and the downward extension 4l6 of the backirest fl 2 byinserting .thepin 426 into another. hole of .theseries-of holes 468 whereby the "angle between the back-rest M2 and theseat 428may be changed. If, furthermore, a change in the zaingle between the leg-rest and theseat is desirable, a such an adjustment may be obtained by varying the position of the pivotal connection :'486-:and'/or 4'80 "by inserting the respective pins ;into other holes of the series: of holes.

When the user'of the chair Wishes to have the seat in a different positionrelative to the backrest "when the latter is in a certainreclinedgposh tion, 'thebac'kn'est is'hel'cl in said position by a tightening of "the locking device 498, while the -Llcckin'g device "446 remains :in loose condition. Now, "the-user of the chair :may brin the seat :intoa different'position relative to the back-rest by altering the position of the pivotal connection 482 and/or 434 by inserting the respective pins into another hole of thezseries of holes 414 and/0M".

Above described change in the position of the 3back+rest 4i2 and/or'the seat 428 causes a change in the degree of change of angularity between the back-rest and the seat during a movement from the sitting position into the reclined position. If the back-rest alone is adjusted in a dif- 'ferent position, the degree of thechange of inclination of the seat will remain substantially unchanged. If the seat alone is adjusted in a 'diiferent position, the degree of the change of inclination-of the back-rest will remain substantially unchanged.

According"to the embodiment of a reclining chair shown in Fig. 5, the rear end portion of the seat 528 is 'swingably mounted on. the support 510 at 515. The upper end portion of the :iron't link 53B is'p'ivo'ted to the seat 528 at 532, the lower end portion of said front link 530 is pivoted to a connecting link 5|8 at 534. Said connecting dink-518 is of bent shape and has its upper end portion pivoted to the support 5" at 520. Furthermore, said bent connecting'llnk 518 has :an extension 562 pivotally connected with'the-rront end of 'a lower link 5'22 at"524. The rear end of said lower link 522 is pivoted at 526 to the downward extension "5H5 of a back-rest 51 2 swin'gably mounted onthe support 510 at 5l-4 at a pointspaced from the pivotal connection 565 between the seat 528 and the support 5111.

.Afleg-rest 5' l6 pivoted to the frontportion of the seat 528 at 518 has an upward extension511.

One end "of a controlling link 542 representing an arm rest is pivoted to said upward extension 51"! of the leg-rest515 at 519, the other end of said controlling link 542 is pivotally connected with the back-west 5L2 at544.

.The sitting position of the movable members of the adjustable reclinin chair is shown in full lines. When the user of the chair leans ithe weight of his body against the back-rest 512, the movable members of the chair are brought into the reclined position shown in dash and dot lines in Fig. 5. During such a displacement of the movable members of the chair from the sitting position into the extreme reclined position, the front end portion of the lower link 522 may pass through a slot 595 of the front wall of the casinglike support I].

The movable members of the chair may be held in any desired position by means of the locking device 546.
