14 Claims. (Cl. 297-S4) The present invention. relates generally to reclining chairs of the type including a movable seat, back-rest and leg-rest, and in particular to improved reclining chairs of the double movement type wherein during the first phase of the reclining movement the leg-rest is moved to an elevated leg-supporting position and during a further phase of the reclining movement the leg-rest remains in an elevated leg-supporting position while the seat and back-rest of the body-supporting unit moves into a final or fully reclined position.
This is a continuation-in-part of my earlier filed application Serial No. 761,822, filed September 18, 1958 entitled Reclining Chair and now abandoned.
The well known reclining chair comprises a support, a back-rest mounted on a support for reclining movement about a back-rest pivot, and a seat mounted on the support or on the back-rest for inclining movement about a seat pivot, with appropriate means for coordinating the inclining movement of the seat to the reclining movement of the back-rest. Usually such reclining chairs also include .a leg-rest which is mounted below the seat for elevating movement to various leg-supporting positions, with an appropriate leg-rest control means operatively connected to the leg-rest for elevating the same in response to the coordinated movement of the backrest and seat of the body-supporting unit.
Of recent times there has been developed an improved reclining chair of the double movement type in which there are two phases of chair movement. During a first phase or portion of the chair movement, the body-supporting unit is moved to an intermediate tilted sitting position and the leg-rest is moved into an elevated legsupporting position such that the several components of the chair comfortably accommodate the chair occupant in an attitude appropriate for viewing television, reading, sewing and the like. During asecond phase or further portion of the reclining movement, the seat and backrest are displaced relative to each other to comfortably accommodate the chair occupant in an attitude appropriate for complete relaxation, with the leg-rest remaining substantially in the elevated leg-supporting position during such further movement. In the final or fully reclined position the chair components are appropriately located relative to each other to enable the chair occupant to completely relax.
Broadly, it is an object of the present invention to provide an improved reclining chair of the double movement type. Specifically, it is within the contemplation of the present invention to provide an improved control arrangement which achieves coordinated movement of the seat and leg-rest in response to reclining movement of the back-rest such that the requisite relative positions of the chair components are realized during the first and second phases of the reclining movement.
In accordance with an illustrative embodiment demonstrating features and advantages of the present invention, my improved reclining chair of the double movement type comprises a support, body-supporting means including a seat and back-rest mounted on the support for inclining and reclining movement respectively, and control means operatively connected between said support and said seat for eifecting coordinated inclining movement of the seatin response to reclining movement of 33%,381 Patented Sept. 10, 1963 the back-rest. The control means includes a first'guid ing means,*a first lost motion means operatively conto one of said seat and said support, and means including a second pivot operatively connecting said first guiding means to the other of said seat and said support. The second lost motion means provides a lost motion travel between said support and one of said second guiding means and said seat as said body-supporting means moves into said intermediate tilted sitting position. The
second guiding means is effective during movement of the body-supporting means into a reclined position to impart a second inclination to the seat, while the first lost motion means provides a lost motion travel between the support and one of the first guiding means and the seat as the body-supporting means moves into the reclined position. In a typical chair, a leg-rest is movably supported and coordinated to the control means to move into an elevated leg-supporting position as the body-supporting means moves into the intermediate tilted sitting position, with the leg-rest remaining in the elevated legsupporting position during movement of the body-supporting means into the reclined position. Advantageously', the several elements of the control means may be mounted by means of pin-and-slot interconnections such that the I FIG. 1 is an elevational view, wtih parts broken away and sectioned, of a reclining chair of the'double movement type demonstrating features of the present invention and shown in the upright or sitting position;

Referring now specifically to the drawings, [there is shown in FIGS. 1-4 a first embodiment of reclining chair of the double movement type demonstrating features of the present invention and generally designated by the reference numeral 10. The chair 10 includes a support .12 having opposite side walls 14, 16 interconnected by appropriate cross-braces or bars 18, 20 and supported on depending legs 22.
Pivotally mounted on the support is a body-supporting unit including a back-rest 24 and a seat 26. The backrest 24- is mounted for reclining movement at a back-rest pivot 28 provided adjacent the lower end of the beck-rest and appropriately connected to the side walls 14, 16 of the support 12. The seat 26 is mounted for inclining movement as a function of or in response to the reclining movement of the back-rest 24 by the provision of rearwardly directed hanger links 30 which have pivotal connections 32 at their forward ends to the seat and pivotal connections 34 at their rearward ends to the back-rest at a point spaced above the back-rest pivot 28.
Disposed beneath the forward end of the seat is a legrest 36 which is mounted for movement from a stored position, illustrated in FIG. 1, contained within the outline of the side walls 14, 16 of the chair frame or support 12, to various elevated leg-supporting positions, as illustrated respectively in FIGS. 2 and 3. In this embodiment the leg-rest 36 is mounted for its elevating movement beneath the forward end of the seat by means of a hanger 38 which has a pivotal connection 40 at its upper end to the seat 26 and is rigidly connected adjacent its lower end to the legrest, as by being riveted or bolted thereto, as indicated by the reference numeral 42. l
Operatively connected between the support 12, the seat 26 and the leg-rest 36 is a combined seat and leg-rest control means which is effective to achieve the coordinated movement of the seat and leg-rest in response to reclining movement of the back-rest as will now be described. The combined seat and leg-rest control means includes a first guiding link 44, which is normally disposed in a forwardly inclined position, as illustrated in FIG. 1. The first guiding link 44 is shown in detail in FIG. 4 and includes an elongated link body 44a which is provided with an elongated slot 44!) extending upwardly from its lowermost end and terminating short of its uppermost end and with a pivot pin opening 440 contiguous to its uppermost end. Fixed to the elongated link body 44a is an offset bracket arm 44d which extends substantially parallel to and is disposed rearwardly of the elongated link body 44a and is provided contiguous to its lowermost end with a connecting pin opening Me. As seen in FIG. 1, the uppermost end of the first guiding link 44 has a pivotal connection to the seat 26 substantially intermediate its ends, the pivotal connection being provided by a pivot pin, 46 which extends into the pivot pin opening 440 in the upper end of chair in the intermediate tilted sitthe elongated link body 44a. The first guiding link 44- is mounted on the support 12 for turning movement about a first pivot and for translating movement relative to the first pivot, and to this end, a first stationary pivot pin 48 is fixed to the support 12 by an appropriate mounting fixture 50, with the pin 48 being slidably received within the elongated slot 44b and normally being disposed contiguous to the upper end of the elongated slot 44b in the upright sitting position of the chair. As will be more fully appreciated as the description proceeds, the pin 48 and slot 44b serve as a lost motion connection which mounts the first guiding link 44 for translating movement relative to the first stationary pivot 48. In accordance with principles which are generally understood, the pin may be provided on the link and the slot on the support to achieve substantially the same action, with the first guiding link 44 being mounted to turn about a pivot and to translate through a lost motion stroke as established by the length of the accommodating slot.
The combined seat and leg-rest control means further includes a second guiding linke 52 which is operatively connected to the seat 26 and is mounted on the support 12 for turning movement about a second stationary pivot and for translating movement relative to the second pivot. In this embodiment, the second guiding link 52 extends forwardly and upwardly from its lowermost end to its uppermost end, with the uppermost end being operatively connected to the seat 26 at the pivotal connection 46. Contiguous to the lower end of the second guiding link 52, there is provided an elongated slot 52a which accomtmodates a second stationary pivot pin 54 which is mounted on the support 12 by an appropriate mounting fixture 56 such that the second stationary pivot pin 5-4 is contiguous to the rearward end of the slot 52:: in the normal or upright sitting position of the chair. Mounting of the second guiding link 52 for turning movement about a second pivot and for translating movement relative to the support also may be achieved by reversal of the pin and slot or lost motion interconnection.
The combined seat and leg-rest control means further include a third guiding link 53 which is openatively connected to the seat 26 contiguous to the rearward end thereof and is mounted on the support 12 for turning movement about -a third fixed or stationary pivot. The third guiding link 58 extends upwardly and forwardly from its lowermost end and is provided with an elongated slot 58a extending downwardly from its uppermost end. The slot 58a accommodates a pivot pin 60 carried on the seat 2 6, with the pin 60 normally being disposed contiguous to the lowermost end of the slot 58a in the normal or upright sitting position of the chair. The lowermost end of the third guiding link 58 is pivotally mounted on the support 12 by means of a stationary pivot pin 62 and an appropriate mounting fixture 64.
In order to move the leg-rest 3d to the requisite elevated leg-supporting position in response to turning movement of the first guiding link 44, there is provided a connecting link 66 which has a pivotal connection 68 at its forward end to the hanger 38 for the leg-rest and has a pivotal connection 70 at its rearward end to the offset bracket arm 44d of the first guiding link at the connecting pin opening 44c. In response to clockwise movement of the lower end of the first guiding link about the stationary pivot 48, a forward thrust is imparted via the connecting link 66 to the hanger 38 which in turn elevates the leg-rest, as may be appreciated by progressively inspecting FIGS. 1 and 2.
In order to facilitate a more thorough understanding of the present invention, a typical sequence of operations will be described, making progressive reference to FIGS. 13 inclusive:
I As the chair occupant leans against the back-rest 24, the back-rest begins to translate rearwardly about the back-rest pivot 28 which in turn causes the seat as to move rearwardly. The portion of the first guiding link 44 intermediate the pivots 46, 48 moves through an upward and rearward arc to impant 1a first inclination to the seat. Preferably, the inclination imparted to the seat is such that there is relatively no angular displacement between the seat and back-rest during the first phase of the reclining movement which terminates as will be described hereinafter. As the seat 26 moves rearwardly, a rearwardly directed thrust is imparted to the second guiding link 52 which translates relative to the second stationary pivot 54 through a lost motion stroke. The third guiding link 58 translates or turns about the pivot 62 with the pin 60 remaining in the lower end of the slot 58a. In response to the turning movement of the first guiding link 44, the bracket arm 44d moves through a forward and upwardly directed are which imparts a forward thrust to the connecting link 66 which in turn moves the leg-rest 36 into successive elevated leg-supporting positions. When the leg-rest 36 arrives at the requiredelevated leg-supporting posit-ion extending forwardly of the seat 26, as illustrated in FIG. 2, and the slot 52a translates relative to the pivot 54- intoan end limit position wherein the forward end of the slot bears against the pivot 54- (which corresponds to the end of the lost motion travel of the second guiding link 52 relative to the stationary pivot 54), the end of the first phase of the reclining movement is substantially completed. It will be appreciated that at the end of such first phase the seat 26 and back-rest 24 are in an intermediate tilted sitting position, as seen in MG. 2, with the leg-rest 36 elevated into the requisite leg-supporting position forwardly of the seat.
As the chair occupant leans funther against the backrest 24 the second phase of the reclining movement is initiated, with the second guiding link 52 translating or turning about the pivot 54 through an upward and rearwardly directed arc to impart a second inclination to the seat. The second guiding link 52 causes the seat 26 to be inclined at a rate such that there is angular displacement between the seat 26 land the back-rest 24'until' (the seat and back-rest are disposed relative to each other to achieve the requisite fully reclined position, illustrated in FIG. 3. As the seat is inclined under control of the second guiding link 52 during the second or further phase of the reclining movement, t e first guiding link 4&4 translates relative to its fixed pivot 48, with such translation or lost motion being permitted by the slot lib. It will be appreciated that the translation of the first guiding link 44 relative to the stationary pivot 48 substantially does not affect the leg-rest 36 which remains in the requisite elevated leg-supponting position forwardly of the seat 26. When the lowermost end of the slot 44b binds against the pivot 48, the lost motion travel of the first guiding link 44 stops and the second or further motion phase ends with the chair fully reclined. During such second or further phase of the motion, the pin 6i? engaged in the slot 58a of the third guiding link 58 translates upwardly along the slot through a lost motion travel. To restore the chair to the upright or normal sitting position, the chair occupant merely leans forward and exerts a pressure on the leg-rest 36 whereupon the chair is restored to the upright sitting position as established by the contact of the rear surface of the leg-rest 36 against the forward cross brace or bar 18 of the support 12 which serves as a stop.
Referring now specifically to FIGS. to 7, there is illustrated diagrammatically a further embodiment of reclining chair of the double movement type demonstrating features of the present invention, and generally designated by the reference numeral 110.
The chair 1111 includes a support 112 having opposite side walls interconnected by appropriate cross-braces or bars and supported on depending legs, which support is similar to that illustrated in FIGS. 1 to 3. Pivotally ary pivot pin 14% mounted on the support isa body-supporting unit including a back-rest 124 and a seat 1 26. The back-rest 124 is mounted for reclining movement at a back-rest pivot 128 provided adjacent the lower end of the backrest 124 and appropriately connected to the support 112. The seat 126 is mounted for inclining movement as a function of or in response to the reclining movement of the back-rest 124 by the provision of rearwardly directed hangers 1% which are rigidly connected at their forward ends to the seat and pivotally connected at their rearward ends to the back-rest at a seat pivot 134 at a point spaced above the back-rest pivot 128.
Disposed beneath the forward end of the seat is a legrest 136 which is mounted for movement from a stored position, illustrated in FIG. 5, to variouselevated legsupporting positions, as illustrated respectively in FIGS. 6 and 7. 'In this embodiment the leg-rest 136 is mounted for its elevating movement from beneath the forward end of the seat by means of a supporting link 138 which has a pivotal connection 140 at its upper end to the seat 126 and is pivotally connected adjacent its lower end to the leg-rest by a connecting link 142 which has a pivotal connection 143 at its forward end to the leg-rest and a pivotal connection 145 at its rearward end to the link 138.
Operatively connected between the support 112, the seat 126 and the leg-rest 136 is a combined seat and legrest control means which is effective to achieve the coordinated movement of'the seat 126 and leg-rest 136 in response to reclining movement of the back-rest 124. The
combined seat and leg-rest control means includes a first guiding link 144, which may be identical to the link 44 illustrated in FIG. 4, and is normally disposed in a forwardly inclined position, as illustrated in FIG. 5. The uppermost end of the first guiding'link 144- has a pivotal connection 146 to the seat 126 substantially intermediate its ends and is mounted on the support 112 for turning movement about a first pivot and for translating movement relative to the first pivot. To this end, a first stationis fixed to the support 112 by an appropriate mounting fixture, with the pin 148 being slidably received within an elongated slot 144:: and normally being disposed contiguous to the upper end of the slot in the upright sitting position of the chair. Thus, the first guiding link 14.4 is mounted to turn about the pivot 148 and to translate relative to the pivot 148 through a lost motion stroke as established by the length of the accommodating slot 14417.
The combined seat and leg-rest control means further includesa second guiding link 2152 which is operatively connected to the seat 126 and is mounted on the support for turning movement about a second pivot and for translating movement relative to the second pivot. In this embodiment, the second guiding link 152 extends forwardly and upwardly from its lowermost end to its uppermost end, with the uppermost end being operatively connected to the seat 126 at the pivotal connection 146. Contiguous to the lower end of the second guiding link there is provided an elongated slot 152a which accommodates a second stationary pivot pin 154 which is mounted on the support .112 such that the second stationary pivot pin is contiguous to the rearward end of the slot 152a in the normal or upright sitting position of the chair. This mounts the second guiding link 152 for turning movement about the second pivot and for translating movement relative to the second pivot through a lost motion stroke.
In order to move the leg-rest 136- to the requisite elevated leg-supporting position in response to turning movement of the first guiding link 144 and to complete the le rest supporting linkage, there is provided a connecting link 166 which has a pivotal connection 168 at its forward end to the leg-rest 136 and has a pivotal connection 170 at its rearward end to the offset bracket arm of the first guiding link 144. The connecting link 166 crosses over the supporting link 138 and has a coordinating pivotal connection 172 thereto. In response to clockwise movement of the ,5 first guiding link 144 about the stationary pivot 114-8, a forward thrust is imparted via the connecting link 1% to the hanger 138 which in turn elevates the leg-rest, as may be appreciated by progressively inspecting FIGS. 5 and 6.
In order to facilitate a more thorough understanding of this embodiment of the present invention, a typical sequence of operations will be described, making progressive reference to FIGS. 5-7 inclusive:
As the chair occupant leans against the back-rest 124', the back-rest begins to translate rearwardly about the backrest pivot 128 which in turn causes the seat 125 to move rearwardly. The portion of the first guiding link 1441 intermediate the pivots 146, 148 moves through an upward and rearward arc to impart a first inclination to the seat. As the seat 126 moves rearwardly, a rearwardiy directed thrust is imparted to the second guiding link 152 which translates relative to the second stationary pivot through a lost motion stroke. In response to the turning movement of the first guiding link 144, the bracket arm moves through a forward and upwardly directed are which imparts a forward thrust to the connecting link 166 which in turn moves the leg-rest 136 into various elevated legsupporting positions. When the leg-rest I136 arrives at the elevated leg-supporting position extending forwardly of the seat 126, as illustrated in FIG. 6, and the pivot 154 binds in the slot 152a, which corresponds to the end of the lost motion travel of the second guiding link 152 relative to the stationary pivot 154, the end of the first phase of the reclining movement is substantially completed. It will be appreciated that at the end of such first phase the seat and back-rest are in an intermediate tilted position as seen in FIG. 6, with the leg-rest elevated into the requisite legsupporting position forwardly of the seat.
As the chair occupant leans further against the backrest 124 the second phase of the reclining movement .is initiated, with the second guiding link 152 translating or turning about the pivot 154 through an upward and rearwardly directed arc to impart a second inclination to the seat. The second guiding link 152 causes the seat to be inclined at a rate such that there is angular displacement between the seat and back-rest such that the seat and back-rest are disposed relative to each other to achieve the requisite fully reclined position illustrated in FIG. 7. As the seat is inclined under control of the second guiding link 152 during the second or further phase of the reclining movement, the first guiding link 144 translates relative to its fixed pivot 148 with such translation or lost motion being permitted by the slot Mel). It will be appreciated that the translation of the first guiding link 144 relative to the stationary pivot 148 substantially does not affect the leg-rest which remains in the requisite elevated leg-supporting position forwardly of the seat. When the lowermost end of the slot M4!) binds against the pivot 148, the lost motion travel of thesecond guiding link stops and the end of the second or further mot-ion phase ends.
Referring now specifically to FIGS. 8 to 10, there is shown a still further embodiments of reclining chair 214) embodying features of the present invention which include a support 212 having opposite side walls 214, 216 interconnected by appropriate crossbraces 218, 22% and supported on depending legs 222. Movably mounted on the support is a body-supporting unit whichincludes a back-rest 224 and a seat 226. Specifically the backrest 224 is mounted for reclining movement about a backrest pivot 228 on a bracket 229 extending longitudinally of and secured to the lower end of the back-rest and appropriately journaled on the side walls onto the support 212. The seat is mounted for inclining movement as a function of and in response to the reclining movement of the back-rest 224 by the provision of a rea-rwardly directed hanger link 23% which has plural rigid connections 232 at spaced locations along its length to the 226 and a pivotal connection 234 at its rearward end to the n C back-rest 224 at a point spaced above the back-rest pivot 228.
Disposed beneath the forward end of the seat 226 is a leg-rest 236 which is mounted :for movement from the stored position illustrated in FIG. 8 to various elevated leg-supporting positions, as illustrated in FIGS. 9 and 10. In this embodiment the leg-rest 236 is mounted for movement by means of a double four-bar leg-rest mounting linkage, generally designated by the reference numeral 233, which is interconnected between the seat 226 and the leg-rest 236. In that the details of the leg-rest mounting linkage are known per se and are subject to a latitude of modification, change and substitution in chairs according to the present invention, further description of the details of the double four-bar leg-rest mounting linkage 238 will be dispensed with in the interest of brevity. The leg-rest 236 is moved to the elevated leg-supporting position during the first movement phase by the provision of a direct ctuating link 239 which has a pivotal mount 24% on the support and a pivotal connection 241 to one of the links of the double ifourubar mounting linkage 238 which is pivotally mounted on the seat 236.
Operative-ly connected between the support 212 and the seat 226 is a control means which is effective to achieve coordinated inclining movement of the seat 226 in response to and as a function of the reclining movement of the back-rest 224. The control means include a first guiding link 2441- which is disposed in an upwardly and forwardly inclined position from its lower end to its upper end, as illustrated in FIG. 8. A lost motion means operatively connects the first guiding link 244 to the seat 226. In this illustrative embodiment of the invention, the lost motion means takes the form of a pin 24-6 fixed to the seat and confined within an elongated slot 248 formed in the first guiding link 244 adjacent the upper and forward end thereof. The lower and rearward ends of the first guiding link 244 has a pivotal mount 25% on the support, the pivotal mount 250 being provided through a bracket fixed to the adjacent side wall of the support 212. The front guiding link is effective during movement of the body-supporting means 224, 226 from the upright or sitting position of FIG. 8 to the intermediate tilted sitting position shown in FIG. 9 to impart a first.
inclination to the seat 226, with the pin 246 remaining at the lower end of the slot 248.
The control means further includes a second guiding link 254 which is disposed in an upwardly and forwardly inclined position from its lower end to the upper end. The second guiding link 254 is operatively connected via a lost motion means to the seat 226. The lost motion means takes the form of a pin 256 fixed to the seat 226 and confined within an elongated slot 258 formed in the upper and forward end of the second guiding link 254. The lower and rearward end of the second guiding link 254 has a pivotal mount 26% on the support via the gggcket 252 at a point spaced from the pivotal mount The second lost motion means 256, 258 provides for a lost motion travel between the second guiding link 254 and the seat 226 as the body-supporting means 224, 226 moves into the intermediate tilted sitting position of FIG. 9. Thereafter the second guiding link 254 is effective during the second movement phase as the body-supporting means moves from the intermediuate tilted sitting position of FIG. 9 to a reclining position of FIG. 10 to impart a second inclination to the seat. The first lost motion means 246, 248 provides for a lost motion travel between the first guiding link 2 54 and the seat 226 as the body-supporting means 224, 226 moves from the intermediate tilted sitting position into the reclining position.
In order to facilitate a more thorough understanding of this embodiment of .the present invention, a typical sequence of operation will be described, making progressive reference to H65. 8 to 10 inclusive:
As the chair occupant leans against the back-rest 224,
the backnest begins to translate rearwardly about the back-rest pivot 22% which in turn causes the seat 226 to move rearwardly. The first guiding link 244 turns in the counterclockwise direction through an upward and rearward are about the pivotal mount 25%, with the pin 246 remaining at the lower end of the slot 245; to impart a first inclination to the seat 226. Concurrently there is a lost motion travel of the pin 256 in the slot 258 .of the second guiding link 254 (see FIGS. 8 and 9). Preferably, the inclination imparted to the seat by the first guiding link 2444 during the first movement phase between the upright or sitting position of FIG. 8 and the intermediate tilted sitting position of FIG. 9 is snch that there is relatively no angular displacement between the back-rest 2 2 and the seat 226. As the seat 226 moves rearwardly, the pivotal mount of the leg-rest linkage 233 on the seat 226 translates relative to the direct actuating link 239 to bring about the necessary extension of the leg-rest 236 to the elevated leg-supporting position. When the legsrest arrives at the elevated legcupporting position in the intermediate tilted sitting position of FIG. 9, the pin 256 of the second lost motion means is at the lower end of the slot 258. Thereafter continued application of pressure against the back-rest 2.24 will cause a lost motion travel of the pin 246 in the slot 248 of the first guiding link 244, with the second guiding link 254 taking over and imparting a second inclination to the seat 225 during the second movement phase from the intermediate tilted position of FIG. 9 to the fully reclining position of FIG. 10.
During the second movement phase, the action of the guiding link 254 on the seat 226 is such that the angle between the seat 226 and the back-rest 224 opens up or increases to establish the desired position for supporting the body of the chair occupant in the fully reclined position of FIG. 10. Further, it is to be noted that during the second movement phase there is a continued elevation of the leg-rest 236 such that the leg-rest is in an appropriate elevated leg-supporting position in relation to the seat 2 26.
Referring now specifically to FIGS. 11 to 13, there is shown a still further embodiment of reclining chair 316 embodying features of the present invention which include a support 3-12 having opposite side walls 314, 316 interconnected by appropriate cross braces 318, 320 and supported on depending legs 322. Movably mounted on the support is a body-supporting unit which includes a back-rest 324 and a seat 326. Specifically, the back-rest 324 is mounted for reclining movement about a backrest pivot 3-28 at the upper end of a bracket 329 extendill-g longitudinally of and secured to the lower end of the back-rest. The back-rest pivot 32% is appropriately journaled on the side walls onto the support 312 at a point spaced above the lower end of the back-rest. The seat 326 rests on the cross brace 318 and is mounted for inclining movement as a function. of and in response to the reclining movement of the back-rest 324- by the provision of rearwardly directed hanger links 330 which have plural rigid connections 332 at spaced locations along their length to the seat 326 and a pivotal connection 334 at its rearward end to the lower end of the backrest 324 at a point spaced below the back-rest pivot 328.
Disposed beneath the for-ward end of the seat 326 is a leg-rest (not shown) which is mounted for movement from a stored position to various elevated leg-supporting positions as disclosed and described in the previou embodiments. In that the details of the leg-rest and its mounting and actuating means are known per se and are subject to a latitude of modification, change and substitution in chairs according to the present invention, detailed description is dispensed within the interest of brevity.
Operatively connected between the support 312,- and the seat 326 is a control means which is effective to achieve coondinated inclining movement of the seat 326 in response to and as a function of the reclining movement of the back-rest 324. The control means include a first guiding link 344 which is disposed in an upwardly and rearwandly inclined position and rests against the cross brace 32%, as illustrated in FIG. 11. A lost motion means openatively connects the first guiding link 3414- to the seat 326. In this illustrative embodiment of the invention, the lost motion means takes the form of a pin 346 fixed to the seat and confined within an elongated slot 348 formed in the first guiding link 344 adjacent the upper and rearwand end thereof. The lower and for- Ward end of the first guiding link 344 has a pivotal mount 35% on the support. The pivotal mount is provided through a bracket 352 fixed direct to the adjacent side wall of the support 3-12. The front guiding link turns forwardly and is effective during movement of the bodysuppo-rting means 324, 326 from the upright or sitting position of FIG. 11 to the intermediate tilted sitting posit-ion shown in FIG. 12 to impart a first inclination to the seat 3-26.
The control means further includes a second guiding link 35 1- which is disposed in a downwardly and rearwardly inclined position fromits upper end to its lower end. The second guiding link 354 is operatively connected at its lower end via a lost motion means to the seat 32b. The lost motion means takes the form of a pin 356 fixed to the seat 326 and confined within an elongated slot 353 formed in the lower and rearward end of the second guiding link 354. The upper and forward end of the second guiding link has a pivotal mount 360 on the support 312 via the bracket 36 2 at a point spaced from the pivotal mount 35%. The second lost motion means 356, 358 provides for a lost motion travel between the second guiding link 35d and the seat 326 as the bodysupporting means 324, 3% moves into the intermediate tilted position (see FIG. 12). Thereafter, the second guiding link 354 is effective during the second movement phase as the body-supporting means moves from the intermediate tilted sitting position to a reclining position to impart a second inclination to the seat. The lost motion means 346, 348 provides for a lost motion travel between the first guiding link 344 and the seat 326 as the body supporting means 324', 326 moves from the intenmediate tilted sitting position into the reclining position (see FIG. 13).
In order to facilitate a more thorough understanding of this embodiment for the present invention, a typical sequence of operation will be described, making progressive reference to FIGS. 11 to 13 inclusive:
As the chair occupant moves against the back-rest 324, the back-rest begins to tnanslate rearwardly about the back-rest pivot 328 which in turn causes the seat 326 to move forwardly. The first guiding link 344 turns in the counter-clockwise directions through an upward and forward are about the pivotal mount 35-9, with the pin 346 remaining at the lower end of the slot 348, and imparts a first inclination to the seat 326. Concurrently there is a lost motion travel of the pin 356 in the slot 358 of the second guiding link 354 (see FIGS. 11 and 12). Preferably the inclination imparted to the seat by the first guiding link 3441- during the first movement phase between the upright or sitting position of FIG. 11 and the intermediate tilted sitting position of FIG. 12 is such that there is relativelyno angular displacement between the back-rest 324- and the seat 326. When the leg-rest (not shown) arrives at the elevated leg-supporting position and the intermediate tilted position is established, the pins 356 of the second lost motion means are at the forward end of the slot 358. Thereafter continued application of pressure against the back-rest will cause a lost motion travel of the pin 346 in the slot 348 of the first guiding link 344, with the second guiding link 354 taking over and imparting :a second inclination to the seat 326 during the second movement phase from the intermediate tilted sitting position of FIG. 12 to the fully reclining position of FiG. 13. During the second movement phase the 1 ll guiding action on the seat 326 is such that the angle between the seat 326 and the back-rest 324 opens up or increases to establish the desired attitude for the chair occupant in the fully reclined position of PEG. 13.
From the foregoing it Will be appreciated that in the several illustrative forms of the present invention, the first guiding means imparts a first inclination to the bodysupporting unit during the first movement phase with a lost motion travel between the second guiding means and either the seat or the support. Specifically, such lost motion travel may be provided by incorporating the lost motion means between the second guiding means and the support or by incorporating the lost motion means between the second "guiding link and the seat.
During the second movement phase, the second guiding means takes over to impart a different inclination to the seat, while there is a lostmotion travel between the support and one of the first guiding means and the seat. Here again the lost motion means may either be provided between the second guiding means and the support or between the second guiding means and the seat.
A latitude of modification, change and substitution is intended in the foregoing disclosure and in some instances some features of the invention will be employed Without a corresponding use of other features. Accordingly it is appropriate that the appended claims be construed broadly and in a manner consistent with the spirit and scope of the invention herein.
