Referring now to Fig. 1, 30 generally indicates a casing-like support. The back-rest 3| and the seat 32 are coaxially pivoted to said support 30 at 33. The back-rest 3| has a downward extension 34 substantially arranged in the center of the chair. The rear end of a connecting link 35 is pivoted to said downward extension 34 of the back-rest 3| at 35, and the front end of said connecting link 35 is pivoted to the'lower end of a controlling link 37 at 38. The upper end of said controlling link 31 is swingably mounted on a transverse rod 39 carried by the support 30. One end of a first controlling arm 40 is rigidly connected with the controlling link 31 adjacent its swingable mounting 39, so that said first controlling arm 43 positively participates in the movements of the controlling link 31. Likewise, one end of a second controlling arm 4| is rigidly connected with the controlling link 31 adjacent its swingable mounting 39 for positive participation in the movements of the controlling link. According to the embodiment shown in Fig. l the controlling link 31, the first controlling arm 45, and the second controlling arm 4| form a controlling member generally indicated by 42, which consists of an integral piece of material. sired, however, the controlling link 3?, the first controlling arm 40, and. the second controlling arm 4| could be made of separate pieces of material, which are rigidly connected with each other in any suitable manner.

The first controlling arm 40 is provided with a controlling surface in the shape of a rotatable roller 43 for displaceable engagement with the lower surface of the seat 32. The lower end of the second controlling arm 4| is'pivotally connected at 44 with one end of a controlling bar 45, the other end of which is pivoted at 46 to a leg-rest 4'! swingably mounted on the front portion of the seat 32 at 48. The front wall of the support 30 is provided with a slot 49 for the passage of said controlling bar and the second controlling arm 4| during movements thereof.

When the occupant of the chair leans the weight of his body against the back-rest 3|, the latter may be swung about its pivot 33 into a reclined position, for example the extreme reclined position 3|. Said swinging movement of the back-rest 3| causes a corresponding swinging movement of the controlling member 42 into the position 42 through the medium of the connecting link 35 connecting the downward extension 34 of the back-rest with said controlling member 42. During said swinging movement of the controlling member 42 into the position 42', the roller 43 of the controlling arm 40 rolls along the lower surface of the seat 32 which is brought into the position 32. Furthermore, during said movement of the controlling member 42 into the position 42, the leg-rest 41 is swung into the position 41' through the medium of the controlling bar 45 connecting the leg-rest 4'! with the second controlling arm 4| of the controlling member 42. When the movable members of the chair are in the reclined position 3|, 32', 41' shown in dash If deand dot lines, and the occupant of the chair leans the weight of his body forward and/or exerts with his legs a slight pressure on the legs, the movable members of the chair will be returned into the sitting position shown in full lines through the positive control of the mechanism described above. Thus, as will be readily understood, the controlling element 42 operatively connected with the seat 32 and the leg-rest 41 controls the movements of said seat and said leg-rest in dependence on movements of the back-rest 3|.

The movable members of the chair may be held in any desired position by means of a looking device generally indicated by 50. As best shown in Figs. 1-3, said locking device 50 includes a clamping sleeve 5| slideaby engaged with a rod 52 attached to an arm-rest 53 swingably mounted on the back-rest 3| at 54. The threaded end 55 of the rod 52 passing through a bore of a block 55 secured to the arm-rest 53 is threaded into a threaded bore of another block 51 secured to the arm-rest 53. A bolt 58 having a head 64 resting against asurface of a member 65 rigidly and immovably connected at El (for example by Welding) with a side wall of the support 30 and having a square portion 59 engaged with a corresponding square aperture of said members 60 is engaged with bores 52 of the clamping sleeve 5|, so that the latter may swing about said bolt 58 when a locking knob 63 screwed on the threaded end of the bolt 58 is loosened. Thus, when said locking knob 63 is loosened, the clamping sleeve 5| and the rod 52 form cooperating sliding means for guiding the arm-rest 53, so that the latter may be brought into the position 53', for example, when the back-rest 3| is brought into the reclined position 3|. When, however, the locking knob 63 is tightened on the bolt 58 prevented from rotation by its square portion 59, the head 64 of the bolt is pressed against the surface of the member 50 and the clamping sleeve 5| is tightly pressed on the rod 52, so that the armrest 53 and the other movable members of the chair connected with said arm-rest are held in a predetermined position.

The sitting position of the movable members of the chair, which is shown in full lines in Fig. 1, is limited by the upper edge of the support 30 on which the seat 32 comes to a rest. The extreme reclined position of the movable members of the chair, which is shown in dash and dot lines in Fig. l, is limited by an abutment of the clamping sleeve 5| against the surface 65 of the block 51- secured to the arm-rest 53 (see Fig. 3).

Fig. 4 illustrates a different embodiment of a controlling member 4211 which may be used in the chair shown in Fig. 1 instead of the controlling member 42. According to Fig. 4 the controlling member 42a is in the shape of a plate having a bore 38a for a pivotal connection with the connecting link, having a bore 39a forengag'ement with the transverse rod, having a bore 43a for receiving the shaft carrying the roller, and having a bore 44a for pivotal connection with the controlling bar.

Furthermore, a recess may be out along the dash and'dot lines 66a into the plate 42a shown in Fig. 4, whereby another embodiment of a controlling member for use in the chair shown in Fig. 1 is obtained.

Fig. 5 illustrates another embodiment of a plate-like controlling member 421), which may be used instead of the controlling member 42 of the chair shown in Fig. 1.

The controlling member 12b shown in Fig. 5 may be obtained by cutting'two recesses into the plate 42a shown in Fig. 4. The 'full plate is indicated in Fig. 5 by cash and dot lines. i

According to the embodiment of a reclining chair shown in Fig. 19 the back-rest 43! and the seat 432 are coaxially pivoted to the support 430 at 433. On each side of the chair one end of a connecting link 435 is pivoted to the downward extension 434 of the back-rest 43! at 436. The other end of each connecting link is pivoted at 438 to a telescopic controlling link 431. Each telescopic controlling link 431 forms a part of a controlling member 442 comprising a first telescopic controlling arm 44!! and a second telescopic controlling arm 44!.

One end of a controlling rod 414 is pivoted to each first controlling arm 448 at 413, the other end of said controlling rod 414 is pivoted to the seat 432 at 415.

A leg-rest 441 swingably mounted on the seat 432 at 448 has an upward extension 482 on'each side of the chair. Furthermore, on each side of the chair one end of a controlling bar 445 is pivoted to said extension 482 at 483, the other end of such a controlling bar 445 being pivoted to the second controlling arm 44! at 444.

When the back-rest 43! is swung into the extreme reclined position 43!, each controlling member 442 is swung into the position 442'. Said swinging movement of the controlling member into the position 442 causes a lifting of the sheet 432 into the position 432' by means of the controlling rods 414 and a displacement of the legrest 441 into the position 441' by means of the controlling bars 445. 7

The movable members of the chair ma be held in any desired position, for example above described extreme reclined position or any other intermediate reclined position, by means of a locking device generally indicated by 484. As best shown in Figs. 20 and 21, said locking device 484 comprises a member 485 swingably mounted at 486 on a lug 481 secured to the seat 432. The member 485 is provided with a longitudinal slot 488 engaged with a bolt 489 having a square portion 499 engaged with 2. corresponding square aperture of an element 49!. Said element 49-! has a lug 492 on each side for abutting engagement with the member 485, which is in slidable engagement with said element 49!. The

' head 493 of the bolt 489 rests against a surface of the element 49!. The bolt 489 passes through the bore 494 of a disk 495, through a bore 496 of a side wall of the support 430, and through a bore 491 of a member 498 attached to the side wall of the support 438 by screws. A locking knob 499 is screwed on the threaded end of said bolt 489-. The square portion 498 of the bolt 489 prevents the latter from rotation when the looking knob 499 is turned. As best shown in Fig.

The other end of said connecting link 535 is pivoted at 538 to the controlling link 53? forming a part of the controlling member 5 32 swingably mounted on the support 530 at 539.

The first controlling arm 545 of said controlling member 552 is rigidly connected with an intermediate point of the second and telescopic controlling arm 54! of said controlling member. The first controlling arm 55!! is provided with a controlling surface in the shape of .a rotatable roller 543 for displaceable engagement with the seat 532. Likewise, the second controlling arm 54! is provided with a controlling surface in the shape of a rotatable roller 50'! for displaceable engagement with the leg-rest 5G? swingably mounted on the seat 552 at 548.

When the back-rest 53! is swung into the extreme reclined position 53!, the controlling member 552 is swung into the position 542'by means of the connecting link 535. Said swinging movement of the controlling member 542 causes a lifting of the seat 532 into the position 532' and'a displacement of the leg-rest 54'! into the position 55'! by means of the

rollers

543 and 50? rolling alongthe seat and leg-rest respectively. I

A different position of the leg-rest 54'! relative to the seat 532 may be obtained by an adjustment of the eifective length of the telescopic controlling arm 54!.

The sitting position of the movable members shown in full lines is limited by the bracing member 555 cooperating with the seat 532, and the extreme reclined position of the movable members is limited by the bracing member 553 cooperating with the back-rest.

The

rollers

543 and 55! of the controlling element 542 are in loose engagement with the seat 552 andthe leg-rest 5 ilrespectively. In order to prevent a collapsing of the mechanism including the back-rest 53!, the extension 534 of the back-rest, the connecting link 535, and the controlling element 542 in a forward direction, when the seat 532 is in its sitting position and the user of the chair gets up from the chair supporting himself on the arm-rests 553 rigidly connected with the back-rest by screws 558, a stop 559 is arranged on the support 535 for abutting engagement with the second controlling arm 54! Of the controlling member 542, when the seat 532 is in said sitting position. Of course, said stop 509 could be arranged at another place of the support for cooperation with another member of the

mechanism

534, 535, 542, and furthermore, said stop could be arranged at a member of said mechanism 534, 535, 552 for cooperation with another member of said mechanism.

According to Fig. 24 the back-rest 63! having a downward extension Us is pivoted to the support 539 at 533. The seat 532 is pivoted to the support 535 at 65? at a point spaced from the ivotal connection 533 between the back-rest 53! and the support 635. One end of a connecting link 535 is pivoted to the extension 535 of the back-rest at 635. The other end of said connecting link 635 is pivoted at 538 to a controlling member 552 swingably mounted on the support 5 at 533. Said controlling member 552 comprises the controlling link 63?, the first controlling arm 545 and the second controlling arm 55! being integral with each other. One end of a controlling rod 556i is pivoted to the first controlling arrn 545 at 513. The other end of said controlling rod 5'! is pivotally connected with a lug 555 of the seat 552 by means of a pin 515. The seat 532 is provided with additional lugs 5!! having bores EH2. If desired, the pin 555 may be disengaged from the bore of the lug Bill and may be inserted into one of the bores N2 of one or the lugs 6! whereby the relative position between the seat 532 and the back-rest 63! may be changed.

The leg-rest 55'! swingably mounted on the seat 632 at 653 is pivoted at 556 to one end of a controlling bar 855. The other end of said controlling bar 555 is pivoted at bit to one end of an adjusting element or bar H3 (see Figs. 24. and 25), the other end of which is swingably mounted on the second controlling arm 55! at 554. A stop 5i5 secured to the controlling arm 64! by screws is arranged for engagement with the swingable adjusting bar Sis so as to hold same in align-ment with the controlling arm 55! as shown in full lines in Fig. 24.

When the back-rest 63! is swung about its pivot 533 into the extreme reclined position 53! shown in dash and dot lines, above described mechanisms cause a movement of the other movable members of the chair into the positions likewise shown in dash and dot lines, i. e. the

seat and the leg-rest are brought into the posi tions 532' and Ml.

The movable members of the chair may be held in any desired position by means of the locking device 555 which is mounted on the element 555 and is of the same construction as the locking device 55 described above in connection with Figs. 1-3.

The sitting position of the movable members of the chair is limited by an abutment of the 532 against the upper edge of the support, and the extreme reclined position of the movable members of the chair is limited by a mem- (5 her of the locking device 555 in cooperation with an element of the arm-rest 553 as described above in connection with Figs. 1-3.

As mentioned above, the adjusting bar 513 is swingable about the pivot 6:4. If the backrest and seat are held in a predetermined position, for example the sitting position shown in full lines in Fig. 24 by means of the locking device 653, the leg-rest 641 may be swung by hand about its pivot 648 into the position 647", wherein the controlling bar and the adjusting bar are in the positions 645", M3" in alignment with each other. Now, when a slight pressure is exerted on the leg-rest, for example by the legs of the occupant resting in the chair, the controlling bar and the adjusting bar are moved beyond said straight line, until a stop 6H5 secured to the adjusting bar 613 by screws abuts against the controlling bar, whereby said elements are locked and held in a predetermined position relative to each other.

According to the embodiment of a reclining chair shown in Fig. 26, the back-rest I3l is pivoted to the support I35 at I33. The rear portion of the seat I32 is pivoted to the support at I61 at a point spaced from the pivotal connection I33 between the back-rest I3! and the support I39. On each side of the chair one end of a connecting link I35 is pivoted to the downward extension I34 of the back-rest I3! at I36. The other end of each connecting link I35 is pivoted at I38 to a controlling link I31, the upper end of which is swingably mounted on the support I38 at I39. One end of a first controlling arm I42 is rigidly connected with each controlling link 73! at the upper end thereof, and the other end of each first controlling arm I46 is pivoted at I13 to a controlling rod I'M pivoted to the seat I32 at I15. A leg-rest I41 is swingably mounted on the seat I32 at I48. One end of a first controlling bar H1 is pivoted at I44 to a second controlling arm I4! being integral with the controlling link 131. The other end of said first controlling bar HT is pivoted at H8 to one end of a second controlling bar H9. The other end of said. second controlling bar H9 is pivoted to the seat I32 at the pivot point I43 between the leg-rest I41 and the seat. The second controlling bar H9 is provided with a controlling surface 120 of cam-like shape (see Figs. 26 and 27). Said controlling surface I26 is arranged for loose contact with a leg-rest I41, which may be held against said controlling surface by means of a spring (not shown). When the leg-rest is in contact with said controlling cam surface I28, the movements of the leg-rest are controlled by said controlling surface I21! of the controlling bar mechanism HI, H9 connected with the second controlling arm I l! of the controlling element I 32, which is formed by the second controlling arm Ml, the controlling link 13? and the first controlling arm I46, and

.which, in turn, is controlled by the connecting link I35 associated with the downward extension I34 of the back-rest T31. Thus, when the back-rest I3! is swung about its pivot I33 into the reclined position I3l', the leg-rest I4? will be brought into the position I47, and the seat I32 will be brought into the position I32, the latter through the medium of the controlling rod 114 connected with the first controlling arm I40 of the controlling element I42.

The movable members of the chair may be held in any desired position by means of the locking device I84 of the type shown in Figs. and 21 which also serves to limit the extreme reclined position of the chair as described above. The sitting position of the movable members of the chair is limited by an abutment of the seat I32 against the upper edge of the support 130. If desired, the leg-rest I41 may be moved independently of the second controlling bar I l 9 relative to the seat I32, as the leg-rest I41 is in loose engagement with the controlling surface I20. ample, the leg-rest I41 may be brought into the position 147", while the other members of the chair remain in the position shown in full lines. The leg-rest may be held in said position 141" by means of a holding device generally indicated by I2l. As best shown in Figs. 2'? and 28, said holding device I2l comprises a rod I22 slideably arranged in a clamping sleeve I23 engaged with a bolt I24 inserted with its square portion I25 into a square aperture of a lug I26 mounted on the seat I32. Said square portion I25 prevents the bolt I24 from rotation when an adjusting knob I2I threaded on the threaded end portion of the bolt I24 is turned. When the adjusting knob 12! is loosened, the rod I22 may be displaced for engagement with the leg-rest in its elevated position 141". Upon a tightening of the adjusting knob I21, the clamping sleeve I23 is tightened on the rod I22 for holding same and the leg-rest in its position. When the movable members of the chair are brought from the sitting position into a reclined position, the leg-rest will remain in the adjusted position 141 relative to the seat I32, until the controlling cam I20 of the second controlling bar H9 abuts against the leg-rest I47, whereupon the controlling cam I20 controls the movements of the leg-rest and displaces same relative to the seat.

Fig. 29 illustrates a different embodiment of a control of the leg-rest I41, which may be substituted for the leg-rest control shown in Figs. 26 and 27. According to Fig. 29, the first controlling bar III is provided with a cam-like control surface I2B in loose contact with the leg-rest pivoted to the seat I32 at I48 for controlling the movements of the leg-rest. Of course, the leg-rest 14! may be disengaged from said controlling surface I28 and may be held in a predetermined position 141" relative to the seat I32 by the holding device 12!, which is of the construction described above in connection with Figs. 27 and 28.

It is understood, that certain parts, elements, or mechanisms shown in a certain figure may be substituted for corresponding parts, elements, or mechanisms of the embodiments shown in other figures of the drawings.

I have described preferred embodiments of my invention, but it is understood that this disclosure is for the purpose of illustration, and that various omissions or changes in shape, proportion, and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described, may be made without department from the spirit and scope of the invention as set forth in the appended claims.
