Fig. 5 is a fs'id'e *eIevationaI new or still another embodimem or an adjustable reclining chair according to the invention, a portion of the side Wallof the support bei'n'g broke'n "away.

Referring now "to Figs. 1 and 2, I 0 generally 'indicates a support in "the "shape of a casing, which may be of any suitable material, such 'as Wood, metal, plasticor the like.

The rear end portion or a seat '28 is pivotedto the support fill at 14. oneac h side O'fthechai'r, the upper :end portion of a controlling link :30 is pivoted to "these'at -28 at 32. The lower end portion 'of said controlling :ilink 3B is pivotally connected at 3 1 \viththe-lowerportion o'f-a'guid ing'link 18, the upper'portionof which is pivoted at 32!] tothe support :I'U at a pointfsp'aced from the pivotal connection M between theseat 28 and theis'uppor't "I'll. Thus, theseat 28, the controlling :link 30,.the guidinglink 18 and'the stationary portion or the support Ill between :the pivotal vconnectionZilrof the guiding link I18 with the support In and the pivotal connectionfll of the seat .28.w-ith thesupport H) form the links of a four-bar link-mechanism.

A back-rest i2 is pivoted to the seat 2 8 at M in coaxial alignment with "the pivotal connection between the seat :28 and the support I10. Said.loack-rest l-2-has adovvnward extension [36 projecting beyond (the pivotal connection M of theback-rest 12 with the :seat 28. According to Fig. 1 said downward'exten'sion I6 is integral with said back-rest l2. On each side of the chair, the rear-end portion of arconnectinglink 22 is pivoted to the downwardextension l'fi of the back-rest l2; at -26 at a poi-ntbelow the pivotal connection llljbetween the ;back- 'rest l2 and the seatyzfl; The frqntend portion of each connect; ing l ink--2-2 is -,pi voted at :24 to an extension .62

3 of the guiding link l8 projecting beyond thepivotal connection 34 of the guidinglink 18 with the controllinglink 38.

As will be apparent from above, theseat 28 and thedownward extension 16 of the back-rest 12 form movable links of a polygonal compound linkage comprising themovable links 28, 38, 18-62, 22, I6 and the stationary link represented by the stationary portion of thesupport 18 between thepivots 14 and 28.

When the user of the chair leans the weight of his body against the back-rest 12 for moving same from its sitting position shown in full lines into the reclined position shown in dash and dot lines, the controllinglink 38 pivotally connected with the guiding link 1862, which in turn is connected with the downward extension- 16 of the back-rest 22 through the medium of the connectinglink 22, controls the movements of theseat 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 back-rest and theseat 28 is increased.

As will be readily understood, the degree of lifting theseat 28 depends on the length of the controllinglink 30 and its connections with the guidinglink 18 and theseat 28. For example, if the controllinglink 38 were of shorter length and were connected with the guidinglink 18 at a point above thepivot 34, theseat 28 would be lifted to a lesser degree when the proportions of above mentioned four-bar link system 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 theseat 28 by the controllinglink 30 pivoted to the guidinglink 18, the designer of the chair has a wide range for obtaining different degrees of inclination of the seat and for obtaining different relative positions between the seat and back-rest in the reclined position so as to make the chair as comfortable as possible for various uses. Furthermore, it may be mentioned, that the arrangement of the movable members of the chair as described above permits a construction of the chair with very well balanced movable members, which may be easily brought from one position into another one. According to the embodiment of the chair shown in Fig. 1, the sitting position of the movable members of the chair is limited by thewall 36 of therecess 38 of the support receiving theseat 28 in its sitting position. The extreme reclined position of the movable members of the chair is limited by theinclinded wall 48 of the support 110 cooperating with the back-rest 12.

On each side of the chair an arm-rest 42 is rigidly secured to the back-rest 12 by screws 44 or the like.

- A locking device generally indicated by 46 may be used for holding the movable members of the chair in any desired adjusted position. According to Figs. 1 and 2, saidlocking device 46 comprises abar 48 swingably mounted ona frame member of theseat 28 at 50. Sambar 48 has aslot 52 for slidable. engagement with abolt 54 having asquare portion 56 inserted into a corresponding square aperture of thesupport 10. Thebolt 54 has on one of its ends a head 58'for engagement with a surface of the bar. Alocking knob 60 is screwed onto the opposite threaded end of thebolt 54 projecting from thesupport 10. If the locking knob 68 is loosened, thebar 48 may be freely moved, so that theseat 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 61] is tightened, so that it clamps thebar 48 by means of thehead 58 and thebolt 54 against thesupport 18, the seat and the movable members of the chair connected therewith are firmly held in their position. t

Fig. 3 illustrates another embodiment of an adjustable reclining chair, wherein a back-rest 312 is pivotally connected with theseat 328 and thesupport 318 at 314. One end of a connectinglink 322 is pivoted to adownward extension 316 of the back-rest 342 at 326, the other end of said connectinglink 322 is pivoted at 324 to an intermediate point of a guidinglink 318 swingably mounted on thesupport 318 at 320. One end of a controlling link 330 is pivoted at 364 to the guidinglink 318; the other end of said controlling link 330 is pivoted at 332 to aseat 328 swingably mounted on thesupport 318 at 314. Anarm rest 342 is rigidly secured to the back-rest 312 at 344. The sitting position of the movable members of the chair limited by thewall 336 is shown in full lines, while the extreme reclined position of the movable members limited by thestop 340 is shown in dash and dot lines;

The mechanism of the adjustable reclining chair shown in Fig. 4 is similar to the mechanism of the adjustable reclining chair shown in Fig. 1. According to Fig. 4 th back-rest 412 pivotally connected with theseat 428 and the support 418 at 414 has adownward extension 416. Said downward extension has a first series ofholes 466 and a second series ofholes 468. Apin 426 passing through a. hole of the connecting link 422 is inserted into one hole of the series ofholes 466 for a pivotal connection between the connecting link and the downward extension of the backrest. The other end of said connecting link.422 being provided with a series of holes 476 is pivotally connected at 424 with the extension 462 of the guiding link 418 swingably. mounted on the support 418 at 428. Saidpivotal connection 424 between the connecting link 422 and the extension of the guiding link 418 is obtained by a pin passing through oneof the holes of the series of holes 418 and inserted into a. registering hole of the guiding link 418. Said guiding link 418 has a series of holes 472, and apin 434 passing through a hole of the controlling link 4311 may be inserted into one hole of said series of holes 4'12 for a pivotal connection between" the controlling link 438 and the guiding link 418. Theseat 428 pivotally mounted on the support 418 at 414 has a series of holes 4'14; a pin 432 passing through a hole of thecontrolling link 430 may be inserted into one hole of said series ofholes 414 for a pivotal connection between the controlling link and the seat. A leg-rest 4'16 pivoted to the front portion of theseat 428 at 4'18 is provided with a series ofholes 480. One end of a controllingmember 482 is provided with a series ofholes 434; said end of the controllingmember 482 is pivotally connected with the leg-rest 476 by means of a pin 486 inserted into one hole of the series ofholes 484 and into a hole of the series ofholes 480. In a similar manner the other end of the controllingmember 482 having a series of holes 488 is pivotally connected with the downward extension 4l6 of the back-rest 412 by means of a pin 458 fitting into one of theholes 468.

482 indicates a side wall of thesupport 410;

5. a substantial portion of saidside wall 492 is detachably mounted on the casing forming the sup.

port 4" by means ofscrews 494, sov that the user of the. chair may have access to the mechanism of the chair after removal of said coveringside wall 492 for a purpose to be described hereinafter. 455 indicates an aperture of the casing 41.0- for the passage of the controlling member 6:82.

The sitting position of the movable member of the chair is limited by astop 496 arranged on the support 4 in for cooperation with theseat 428, and the extreme reclined position of the movable members of the chair is limited by the inclined wall 2% cooperating with the back-rest.

. The. adjustable reclining chair shown in Fig. 4 is equipped with a first locking device generally indicated by M6 and a second locking device general-ly indicated by 498. Both locking devices are. of the type shown in Fig. 2- and described above in connection with the chair shown in Fig. 1. The locking bar MB of the first locking device 4416 is-swingably mounted on theseat 428 at 553), so that said locking device 445 is associated with the seat and the support; the locking bar 49! of thesecond locking device 498 is swingably mounted on the guiding link M8 at 399, so that the second locking device 198 is associated with said guiding link M8 and the support 3H]. If the movable members of the chair are connected with each other as shown in Fig. 4, they may be held in any desired adjusted position by tightening either one of thelocking devices 445 or 498,.

If the user of the chair wishes to have the backrest at a different angle relative to the seat when the latter is in a certain position, he may hold the seat in said certain position by a tightening of the locking device M6. The other locking de-. vice 498 remains in loose condition. Now, the user of the chair may change the position of thepivotal connection 426 between the connecting link 422 and the downward. extension M6 of the back-rest M2 by inserting the pin 425 into an-. other hole of the series of holes 456, whereby the. angle between the bask-rest M2 and the seat 428: may be changed. If, furthermore, a change in the angle between the leg-rest and the seat is desirable, such an adjustment may be obtained by varying the position of the pivotal connection @85 and/or 490 by inserting the respective pins into. other holes of the series of holes.

When the user of the chair wishes to havethe.

seat in a different position relative to the ba ckrest when the latter is in a certain reclined posi-v tion, the back-rest; is held in said position by a.

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 different po sition,the degree of the change of ihe clination of the seat will remain substantially un changed. If the seat alone is adjusted in a, different position, the degreeof the change of inclination of the back-rest will remain substantially unhan ed:
