Pfffl? SI IZETC/V? BYA'MFU w United States Patent 1 3,157,431 nncinsmt; cnAm or rent MULTHPLE wrovasrsrrr TYZZFE The present invention relates generally to reclining chairs, and in particular to an improved reclining chair of the type including body-supporting means having a movable back-rest and a movable seat which are coordinated with each other to include two distinct phases of chair movement. This is a continuation of my copending application of the same title, Serial No. 8,564, filed on February 15, 1960.

The well known reclining chair comprises a support, body-supporting means including a back-rest and seat movably mounted on the support and a leg-rest mounted beneath the seat and movable into various elevated legsupported positions in response to chair movement. Heretofore there has been two distinct types of reclining chair, those constructed with a unitary back-rest and seat mounted on a support for movement into various tilted positions and those constructed with a movable back-rest and movable seat and mounted on the support for reclining and inclining movement respectively. Chairs of the type incorporating a unitary back-rest and seat were found to be most suitable for accommodating the chair occupant in a tilted back position, but in a sitting attitude, with the occupants leg supported on the elevated leg-rest. Chairs of the type incorporating a movable back-rest and movable seat were found to be most suitable for accommodating the chair occupant in a fully reclined or complete relaxation position, with the occupants legs supported on the leg-rest, in that the angle between the backrest and seat increased in response to the reclining movement of the chair.

Of recent time there has been introduced an improved reclin'mg chair which exhibits attributes of both types of chairs which have been heretofore sold, to wit, those suitable for accommodating the chair occupant in tilted sitting attitude and those suitable for accommodating the chair occupant in a fully reclined or complete relaxation attitude. Provision is made in such chairs of the double movement type for a first movement phase from an upright sitting position to an intermediate, tilted sitting position during which there is substantially no angular displacement between the back-rest and seat, with the legrest moving to an elevated leg-supporting position to establish the intermediate, tilted sitting position, and for a second movement phase from the intermediate, tilted sitting position to a fully reclined position during which the angle between the seat and back-rest opens up, with the leg-rest remaining in an elevated leg-supporting position to establish a complete relaxation or fully reclined position for the chair occupant.

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 improved and simplified coordinating mechanisms for establishing two distinct phases of movement in a reclining chair.

In accordance with an illustrative embodiment demonstrating objects and features of the present invention, there is provided a reclining chair which comprises a support, body-supporting means including a seat and back-rest adapted to be mounted on the support for inclining and reclining movement respectively, and a control linkage operatively connected between the support ice and the body-supporting means and providing respective first and second paths of movement for the body-supporting means during first and second movement phases. A holding link cooperates with the control linkage during either phase to maintain a substantially rigid relationship between any two preselected links. In the phase in which the rigid relationship of the two preselected links is not desired, the holding link is arranged to be inactive to allow movement to occur between the two preselected links in a manner determined by the control linkage and the desired chair movement.

in a typical construction according to the invention, the body-supporting means is guided during the first movement phase by two links, with the holding link keeping the seat and back-rest rigid with each other. With such construction, it is possible to establish a high order of control over chair balance, and, if necessary, to slightly open up the included angle between the seat and back-rest during the first movement phase in order to attain a more comfortable intermediate, tilted sitting position for the chair. For example, in a reclining chain designed specifically for use at a desk in an ofiice, the included angle between the seat and back-rest in the upright sitting position preferably is arranged relatively close to a right angle in order to provide the most comfortable attitude for the chair occupant when seated at the desk. However, when such chair is moved through the first movement phase to the intermediate, tilted sitting position, such included angle is not suited for optimum comfort; and for such application, provision may be made in accordance with the present invention to slightly open the included angle between the seat and back-rest to afford optimum comfort in the intermediate, tilted sitting position.

The above brief description as well as further objects, features and advantages of the present invention will be more fully appreciated by reference to the following detailed description of several illustrative embodiments according to the present invention, when taken in conjunction with the accompanying drawings, wherein:

I Referring now specifically to FIGS. 1 to 3 of the drawings, there is shown a first embodiment of reclining chair demonstrating features of the present invention, generally designated by the reference numeral 10, which includes a support or frame 12 having opposite side walls 14 interconnected by suitable cross braces 16 and supported on depending legs 1%. V

Body-supporting means. 2% including a back-rest 22 V and a seat 24 are mounted on the support 12 for reclinin and inclining movement respectively for a'first movement *phase from anupright position illustrated in FIG. 1 to an intermediate, tilted sitting position illustrated in F16.

: 2 and for a second movement phasefrom the intermediate, tilted sitting position illustrated in FIG. 2

through a series of reclining positions to a fully reclined or complete relaxation position illustrated in FiG. 3. Disposed beneath the forward end of the seat 2 is a leg-rest 26 which is mounted for movementrfrom a stored or retracted position shown in FIG. 1 to elevated legsupporting positions shown in FIGS. 2 and 3. As will be described, the leg-rest 26 .is coordinated to the backrest 22 and the seat 24 for movement into an elevated leg-supporting position in response to the first movement phase or" the chair, with the leg-rest remaining substantially in the elevated leg-supporting position as the chair moves from the intermediate, tilted sitting position QfpFIG. 2 to the fully reclined position of FIG. 3.

' In this illustrative embodiment, the seat 24' carries a rearwardly' directed rigid hanger arm 23 which is connected to the back-restZZ at a seat pivot 3'9. Front guiding means, generally designated by the reference numeral 32, are operatively connected between the support 12 and the seat 24 which front guiding means are operative during thefirst and second movement phases of the chair. The front guiding means includes a first link 34' extending rearwardly and downwardly from its upper end to its lower end and having a pivotal mount 55 at its upper end on the support 12; Extending upwardly from the lowercnd of the first link 34 is a second link 33 which has a pivotal connection it} at its lower end to the lower end of the firstlink 34 and a pivotal connection The links 34, 33

tion 49 and/ or the lower end of the link 34 rests on the cross brace 16 serving as a stop. The link 33 turns in the clockwise direction about the pivotal connection 45?, serving as a relatively stationary pivotal mount, during the first movement phase, and the link 34 turns in the counterclockwise direction about the stationary pivotal mount 36 during the second movement phase.

Rearguiding means, generally designated by the reference numeral 44, are operatively connected between the back-rest 22 and the support 12 for guiding the rearward portion of the body-supporting means during the first movement phase, with the rear guiding means remaining stationary relative to the support 12 and providing a back-rest pivot during thesecond movement phase. In this illustrative embodiment, therear guiding means 44 includes a rear guiding link 46 which has a pivotal mount 48 at its lower end on the support 12 and a pivotal connection 50 at its upper end to the back-rest 22 at a point spaced from the seat pivot 3%.,

to the rearward end of the flexible It will be appreciated that the portion of the back-rest 22 intermediate the seat pivot 39 and the pivotal connection 551 efiectively provides a link'which is rigid or integral with thebackrest 22.

In accordance with the present invention, provision is made for precluding appreciable relative movement between the back-rest 22 and the seat 24- during the first movement phase such that the intermediate, tilted sitting,

position of FIG. 2 is established with substantially no change in the angular relationship between the back-rest and seat, except for small adjustments in the included angle therebetween as may be required for balance and/or forestablishinga more comfortable attitude in such intermediate, tilted sitting position. Specifically, a'holding link 52 is flexibly mounted for pivotal movement about a relatively fixed pivot during the first movement phase and for inactive displacement relative to the support 12 during the-second movement phase. in this illustrative embodiment, the flexible'mounting for the holding link 52 includes a mountinglink 4 which rests against the adjacent cross brace in during the first movement phase. The mounting link 54 is pivotaily mounted at its forward end on the front guiding means 32 atthe pivotal connection 4i and remains stationary relative to the support during the first movement phase. The holding link 52 has a pivotal connection 52; at its lower end and a pivotal connection 63' at its upper end to the seat 24 at a point rearwardly of the pivotal connection 42 During the first movement phase, the body-supporting means 20 is guided by two links, namely the front guiding link 38 and the rear guiding link .46, with the holding 'link' positioned and pivotally connected to the linkage in such a way that it serves substantially thesame function as a stop between the seat and back-rest to effectively maintain a rigid relationship therebetween, i.e., the pivot point 6h is guided by the holding .link 52 to move throughrsubstantially the same path that it would travel if the seat 24 and back-rest 2.2,v were rigid. The flexibility of the described arrangement canbe appreciated in that 7 individual guiding of the seat and back-rest during the first movement ment in chair balance and/or the angular relationsh p between the back-rest 22 and the seat 254 during the first also blocking turning movement of the rear guiding link 7 do about itspivotal mount 4-3. Specifically, the flexible mounting link 54 carries an upstanding stop 62 located rearwardly of the pivotal connection 4%) which stop abuts V the front guiding link 38 at the end or" the first movement phase and for all intents and purposes, renders the

links

38, 54, 52 rigid with each other and with the seat 24 during the second movement phase. Further, a stop 64 is located rearwardly of the pivotal mount 43 of the rear guiding link as to abut the link as at the end of the first moveme, t phase and to preclude further clockwise movement of such rear guide link aboutits pivotal mount 43. i V

The first movement linkage includes links thereof, the front guiding link 33, by the portion of the seatZd back-rest 22 intermediate the pivotal connection 42 and the pivotal connection 56, and the rear guiding link 46, with a stationary link being provided intermediate the pivotal connection 4% and the pivotal mount 48 and with the holding link the desired rigid relationship between the seat and backthe link formed rest. The second movement linkage includes as the movmounting link 54- phase is possible which enables adjustas the movable and the portion of the acting effectively as a stop, to maintain connection 44 and the seat pivot 3t), and the portion of the back-rest intermediate the seat pivot 34) and the pivotal connection 50, with a stationary link being provided intermediate the pivotal mount 36 and the pivotal connection 50.

In this illustrative embodiment, the leg-rest 2:5 is mounted for movement from the retracted position of FIG. 1 to the elevated leg-supporting positions illustrated in FIGS. 2 and 3 by a leg-rest mounting linkage including a hanger arm 66 which has a rigid connection 68 adjacent its lower end to the leg-rest 26.. The hanger arm 66 is suspended from a carrier link 79 which rests on a stop 72 and has a pivotal mount 7-4 adjacent its rearward end on the support. The carrier link 7% is connected to the hanger arm 66 by first and second connecting

links

76, 78. Specifically, in the position shown in FIG. 1 the connecting link 76 has a pivotal connection 86 at its lower end on the forward end of the carrier link 79 and a pivotal connection 82 at its upper end on the hanger arm 32, while the connecting link 78 has a pivotal connection 8 2- at its lower end to the carrier link 79 at a point spaced from the pivotal connection 8:) and a pivotal connection 86 at its upper end to the hanger arm 66 at a point spaced from the pivotal connection 32. The hanger arm 66 of the leg-rest mounting linkage is coupled to the seat 24 of the body-supporting means 2% by a double-arm actuating lever 88 which has a pivotal mount 9% intermediate its ends on the support. The upwardly extending arm 83a of lever 88 is coupled to the seat 24 by a connecting link 92 having a pivotal connection 94 at its forward end to the arm 88a and a pivotal connection at its remward end to the seat 24 ,coaxially of the pivotal connection 69. The arm 88!) of the lever 88 is coupled to the hange arm 66 by a connecting link 95 having a pivotal connection 97 at its rearward end to the arm 88]) and a pivotal connection 93 at its forward end to the hanger arm 66. During the first movement phase, the carrier link 76 remains stationary relative to the support such that the

pivotal connections

88, 84 of the links '76, 78 serve as relatively stationary pivotal mounts for the leg-rest mounting linkage, with the

links

76, 78 turning in the clockwise direction incident to turning movement of the double-arm actuating lever 88. At the end of the first movement phase, the leg-rest mounting linkage is blocke by the link 76 coming into contact with the pivot 84 serving as a stop and thereby providing a substantially rigid interconnection between the hanger arm 66 and the carrier link 7 Thereafter the pivotal mount 74 of the carrier link serves as a stationary pivotal mount about which the leg-rest 2:: swings during the second movement phase, as may be appreciated by progressively inspecting FIGS. 2 and 3. Thus, the leg-rest 2e moves from the stored position illustrated in FIG. 1 during the first movement phase to the first elevated leg-supporting position illustrated in FIG. 2; and then moves during the second movement phase from the elevated legsupporting position illustrated in PEG. 2 to a further elevated leg-supporting position illustrated in Fl. 3, the carrier link 76 turning in the clockwise direction about the pivotal mount '74.

For a better understanding of this illustrative embodiment of the present invention, reference will now be made to a typical sequence of operations:

When the chair occupant is seated in the chair lb and leans against the back-rest 22, the body-supporting means 24 is displaced rearwardly and tilted relative to the support, with substantially no angular displacement between the back-rest 22 and the seat 24. During such first movement phase, the holding link 2 maintains the desired relationship between the back-rest 22 and the seat 24 with no angular change therebetween, or a slight opening of the angle therebetween as previously described. Incident to such rearward movement of body-supporting means 29, the requisite turning movement is imparted to the double-arm lever 33 to move the leg-rest 26 to the elevated leg-supporting position. The end of the first movement phase is established when the link 33 abuts the stop 62 and when simultaneously the rear guiding link 46 abuts the stop 64. At such time, and as illustrated in FIG. 2, the

links

33, 54 and 52 become substantially unitary with the seat 24 and efiectively the seat and the linkage intermediate the pivotal connection 49 and the seat pivot 3i? define a single movable link for the second movement phase. When the rear guiding link 4-5 abuts the stop 64, the rear guiding link 46 becomes unitary with the support 12 for all intents and purposes, and thereafter the pivotal connection 5% to the back-rest 22 serves as a stationary pivot for the second movement phase.

When the chair occupant exerts continued pressure with the chair in the intermediate, tilted sitting position of 1G. 2, the back-rest 22 begins to turn about the relatively feted or stationary pivotal mount 5%, with the seat being guided by the second movement link 34 which turns in the counterclockwise direction about the pivotal mount 36. As may be appreciated by progressively inspecting PEG-S. 2 and 3, the action of the front guiding means 32 is to guide the seat 24 generally upwardly while the back-rest 22 is turning about the pivotal connection such that the included angle between the back-rest and seat opens up to establish the fully reciined position of FIG. 3. The second movement phase continues until such time as the second movement linkage is blocked, for example, by contact with a further stationary stop or by the movement of the second movement link into substantial alignment with the link defined between the pivotal connection 49 and the seat pivot 3%). D .ring such second movement, a relatively small thrust is imparted to the leg-rest linkage which is effective to turn the carrier link 7% from its position resting against the stop 72 through a slight upward arc to establish a further elevated position for the leg-rest 26.

When the chair occupant desires to restore the chair to the upright sitting position illustrated in FIG. 1, the occupant leans forward such that the back-rest, seat and leg-rest move through the reverse sequence with the chair first moving into the intermediate, tilted sitting position of PEG. 2 and then returning to the upright sitting position illustrated in FIG. 1.

it will be appreciated that the holding link 52 and its exible mounting functions during the first movement phase to provide a substantially rigid relationship between two movable m mbers of the control linkage (i.e. the link portions provided by the seat and back-rest); and during the second movement phase the holding link is functionally inactive, that is, it does not serve to guide the body-supporting means in its movement so as to maintain the aforementioned rigid relationship between the two movable members of the control linkage but allows them to move in a manner determined by the guiding action of the control linkage in the second movement phase. By appropriate design of the control linkage, a high order of flexibility is afforded in the control of the body-supporting means with the use of such holding links, as compared for example to chairs of the type wherein the rigid relationship for the seat and backrest of the body-supporting means is established during the first movement phase by the provision of a stop.

Referring now specifically to FIGS. 4 to 6 of the drawings, there is shown a second embodiment of reclining chair demonstrating features of the present invention, generally designated by the reference numeral 110, which includes a support or frame 112 having opposite side walls 114 interconnected by suitable cross braces 116 and supported on depending legs 113.

Body-supporting means 12% including a back-rest 122 and a seat 124- are mounted on the support 112 for reclining and inclining movement respectively for a first movement phase from an upright sitting position illustrated in FIG. 4 to an intermediate, tilted sitting position illustrated in PEG. 5 and for a second movement phase nd movement phase.

from the seat pivot 13%.

portion of the back-rest 122 intermediate the seat pivot I 13% and the pivotal connection 15% efiectively provides from the intermediate, tilted sitting position illustrated in FiGJS through a series of reclining positions to a fully reclined or complete relaxatio'n position illustrated in FlGI6, l I I Y i Disposed beneath the forward end of the seat 124 is a leg-rest 126 which is mounted for movement from a stored or retracted position shown in FIG. 4 to elevated leg-supporting positionsshown in FIGS. Sand 6. As Will be described, the leg-rest 126 is coordinated to the back-rest 122 and theseat 124 for movement into an ele 'vated leg-supporting position in response to the first movement phaseof the chair, with the leg-rest remaining substantially in the elevated leg-supporting position as the chair moves from the intermediate, tilted sitting position of FIG. to the fully reclined position of FIG. 6.

In this illustrative embodiment, the seat 124 carries a rearwardly directed rigid hanger arm 11.8 which is connected to the back-rest 122 at a seat pivot Front guiding means, generally designated by the reference numeral'132, are operatively connected between the support 112 and the seat 124 which front guiding means are operative during the first and second movement phases of the chair. The front guiding means includes a first link 134' extending rearwardly and downwardly from its upper end to its lower end and having a pivotal mount lower end to the lower end of the first rink 134 and a I pivotal connection 142 at its upper end to the seat 124.

The links 134, 133 are arranged. such that the interinedite pivotal connection 148' and/or the lower end of the link 134 rests on the cross brace 1116 serving as a stop. The link 13% turns in the clockwise direction about the pivotalconnection 14$ serving as a relatively stationary pivotal mount during the first movement phase, and the link 1134 turns in the counterclockwise direction about the stationary pivotal mount 136 during the secproviding a back-rest pivot during the second movement phase.

In this illustrative embodiment, the rear guiding means 144 includes a rear guiding link 146 which has a relatively fixed pivotal mount'143 at its lower end on afiexible mounting link 154 and a pivotal connection 159 at its upper end to the back-rest 122 at a point spaced It will be appreciated that the alink rigid or integral with the back-rest 122.

Provision is made for precluding appreciable relative movement between the back-rest 122 and the seat 124 during the first movement phase such thatthe intermediate, tilted sitting position of FIG. 5 is established with substantially no change in the angular relationship between the back-rest and seat, except for some small adjustments in the included angletherebetween as may be required for balance and/ or for establishing a more comfortable attitude in such intermediate, tilted sitting position. Specifically, a holding link 152 is mounted onthe mounting link 154 for pivotal movement about a relatively fixed pivot during the first movement phase and for inactive displacement relative to the support during the second movement phase. In the upright sitting position and during the first movement phase, the mounting link 154 rests against a stop 155 and is pivotally mounted at its rearward end on the support at a pivotal mount 157 for movement relative to the support during the second movement phase. The holding link 1552 has a pivotal connection 156 at its lower end to the forward end of the flexible mounting link 154 and a pivotal con generally designated by the refern ection tea at its upper end; to the back-restll22 at a point forwardly of the pivotal connection 15%. Effectively, during the firstmovement phase the body supporting means 124? is guided by two links, namely. the

- front guiding link 1338 and the rear guiding link 1145;

the angular relationship between the back-rest 122 and the seat 124 duringthe first movement phase.

Provision is made for blocking relative movement between the link 138 of the front guiding means 132 and the seat 124 at the end of the first movement phase.- Specifically, :the'seat 124 carries a depending stop 162 forwardly of the pivotal connection 142 which stop abuts the front guiding link 13% at the end of the first movement phase and renders the link138 rigid with the seat during the second movement'phase. made for blocking the rear guide link by means of the stop 147.

In this illustrative embodimen the leg-rest 126 is mounted for movement from the retracted position of PEG. 4 to the elevated leg-supporting positions of FIGS. 5 and. 6 by a leg-rest mounting linkage which includes a hanger arm res which has a pivotal connection 168 at its lower end to the leg-rest 12s and a pivotal mount 1749 at its upper end on the support 112. The hanger arm 166 and the leg-rest 126 are coupled via a chain of links to the body-supporting means 1243, which chain of links includes 7 connecting

links

172, 174, a guiding link 176, a further arm level 189 has a pivotal connection 183 to the rearward end of the connecting link 178, with the forward end of'the link 178 having a pivotal connection 199 to the guiding link 17:? inte mediate the ends thereof. The guiding ink 176 has a pivotal mount192 at its lower end on the support, with the upper end thereof having a pivotal connection 1% tojthe rearward end of the connecting link 172. The connecting link 172 has a pivotal connection 1% adjacent its forward end to the hanger arm 166 at a point speed above the pivotal connection 168. Finally, the connecting link 174 has a pivotal connection 197.

at its rearward end to the connecting link 172' intermediate tne'ends thereof, and a pivotal connection 198 at'its for: j ward end to the leg-rest at a point spaced above the pivotal connection During the first and second movement 7 phases, and in'response to reclining movement of the backrest 12% a turning movement is imparted to the double arm lever 18-h which, via the connecting link 17% turns the guiding link 176 in the counterclockwise direction about its pivotal mount 192 to impait an upwardand forward thrust via the connecting

links

172, 174 to the arm .166. and leg-rest 12s; such that the leg-rest moves to successive elevated leg-supporting positions, as shown in FIGS. 5 and 6. a

For a better understanding of this illustrative embodiment of the present invention, reference will now be made to a typical sequence of operation:.

When the chair occupant is seated in the chair 111i? and leans against the back-rest 122 of the body-supporting means 124 the body-supporting means is displaced rearwardly and tilted relative to the support, with substantially no angulardisplacement between the back-rest 122 and 7 During such first movement phase, the

the seat 12 Provision is also holding link 152 maintains the desired relationship between the back-rest 122 and the seat 124, with no angular change therebetween or a slight opening of the angle therebetween. Incident to such rearward movement of body-supporting means 12%, the requisite turning movement is imparted to the double-arm level 189 to move the leg-rest 126 to the elevated leg-supporting position. The end of the first movement phase is established when the link 133 abuts the stop 162. At such time, and as illustrated in FIG. 5, the link 138 becomes substantial y unitary with the seat 124 and effectively they define a single movable link for the second movement phase intermediate the pivotal connection 14% and the seat pivot 13%). Sim taneously, the pivotal connection 15% moves into coaxial relation with the pivotal mount 157 of the mounting link 154 and the rear guiding link 1 .5 abuts the stop 147. Thereafter the pivotal connection 159 to the back-rest 122 serves as a relatively stationary pivot for the second movement phase.

When the chair occupant exerts continued ressure, with the chair in the intermediate, tilted sitting position of FIG. 6, the back-rest 122 begins to turn about the relatively fixed or stationary pivotal mount or aids at 15%, with the seat 124 being guided by the link 13 which turns in the counterclockwise direction about the pivotal mount 136. As may be appreciated by progressively inspecting FIGS. 5 and 6, the action of the front guiding means 132 is to guide the seat 124 generally upwardly while the back rest 122 is turning about the pivotal connection such that the included angle between the back-rest and seat opens up to establish the fully reclined position of PEG. 6.

Referring now specifically to FiGS. 7 to 9 of the drawings, there is shown a third embodiment of reclining chair demonstrating features of the present invention, generally designated by the reference numeral 210, which includes a support or frame 212 having opposite side walls 214 interconnected by suitable cross braces 215 and supported on depending legs 218.

Body-supporting means 22%) including a back-rest 222 and a seat 224 are mounted on the support 212 for reclining and inclin ng movement respectively for a first movement phase from an upright sitting position illustrated in FIG. 7 to an intermediate, tilted sitting position illustrated in FIG. 8 and for a second movement phase from the intermediate, tilted sitting position illustrated in FIG. 8 through a series of reclining positions to a fully reclined or complete relaxation position illustrated in FIG. 9.

Disposed beneath the forward end of the seat 224 is a leg-rest 226 which is mounted for movement from a stored or retracted position shown in FIG. 7 to elevated leg-supporting position shown in FIGS. 8 and 9. As will be described, the leg-rest 226 is coordinated to the back-rest 222 and the seat 224- for movement into an elevated legsupporting position in response to the first movement phase of the chair, with the leg-rest 226 remaining substantially in the elevated leg-supporting position as the chair moves from the intermediate, tilted sitting position of FIG. 8 to the fully reclined position of FIG. 9. The seat 224 carries a rearwardly directed rigid hanger arm 22% which is connected to the back-rest 222 at a seat pivot 23%. Front guiding means, generally designated by the reference numeral 232, are operatively connected between the support 212 and the seat 224 which front guiding means are operative during the first and second movement phases of the chair. In this illustrative embodiment, the front guiding means includes a first link 234 extending substantially horizontally and having a pivotal mount 236 at its rearward end on the support 212. Extending upwardly from the front end of the first link 234 is a second link 238 which has a pivotal connection 249 at its lower end to the front end of the first link 234 and the pivotal connection 242 at its upper end to the seat 224. The link 234 is arranged to rest on the cross brace 216 serving as a stop during the first movement phase. The link 233 turns in the clockwise direction about the pivotal connection 24% serving as a relatively stationary pivotal mount during the first movement phase, and the link 234 turns in the clockwise direction about the stationary pivotal mount 23% during the second movement phase.

Rear guiding means, generally designated by the reference numeral 244, are operatively connected between the back-rest 222 and the support 212 for guiding the rearward portion of the body-supporting means during the first movement phase, with the rear guiding means remaining stationary relative to the support and providing a back-rest pivot during the second movement phase. In this illustrative embodiment, the rear guiding means 244 includes a rear guiding link 246 which as a pivotal mount 248 at its lower end on the support 212 and a pivotal connection 259 at its upper end to the back-rest 222 at a point spaced from the seat pivot 236.

In accordance with this embodiment of the present invention, provision is made for precluding appreciable relative movement between the back-rest 222 and the seat 224 during the first movement phase such that the intermediate, tilted sitting position of FIG. 8 is established with substantially no change in the angular relationship between the back-rest and seat, and for precluding appreciable relative movement between the rear guide means and the support during the second movement phase. Specifically, there is provided a first holding link 252 which is mounted for pivotal movement about a relatively fixed pivot during the first phase and for inactive displacement relative to the support during the second movement phase. The flexible mounting arrangement for the first holding link 2132 in this illustrative embodiment includes a mounting link 254 which rests against the adjacent cross brace 226 during the first movement phase and is movably mounted at its forward end on the front guiding means 232 and at its rearward and on a second holding link 253. Specifically, the adjacent ends of the first and second holding links 252, 253 have a common pivotal connection 256 to the rearward end of the mounting link 2254, with the forward end thereof having a pivotal connection to the adjacent ends of the links 234, 233 at the pivotal connection 24%. The first holding link 252 has a pivotal connection 266 at its upper end to the seat 22%, while the second holding link has a pivotal mount 2&1 at its lower end on the support. Effectively during the first movement phase the movement of the body-supporting means is determined by two links, namely the front guiding link 23%, and the rear guiding link 246, with the mounting link 254 remaining stationary and resting against the cross brace 216 and with the holding link 252 maintaining a substantially rigid relationship between the seat 224 and the back-rest 222.

Provision is made for blocking relative movement between the link 238 of the front guiding means 232 and the seat 224 at the end of the first movement phase. Specifically, the flexible mounting link 254- carries an upstanding stop 2 52 rearwardly of the pivotal connection 24-9 which stop abuts the front guiding link 233 at the end of the first movement phase and renders the links 238, 254-, 252 rigid with each other and with the seat 224 during the second movement phase.

During the second movement phase, the second holding link 253 is effective to hold the rear guiding link 246 substantially rigid with the support. The second holding link 253 functionally replaces the stop 64 shown in the first embodiment, and during the second movement phase, substantially precludes turning movement of the rear guiding link 246 about its pivotal mount 248, such that the pivotal connection 259 thereof to the back-rest 222 eifectively serves as a back-rest pivot during the second movement phase. Although the second holding link 253 may be'considered to be part of the second move ment linkage wherein the mounting link 25 4, the seat and the blocked links therebetween comprise one movable link and wherein the second movement link 234 and the The first movement guiding linkage includes as the,

movable links thereof, the front guiding link 23%, the portion ofthe. seat 224 and the portion or" the back-rest 222 intermediate the pivotal connection 242 and the pivotal connectionzdtl, and the rear guiding link 2-46, with a relatively stationary link being provided intermediate the pivotal connection 245)- and the pivotal mount 24% and.

with the first holding link ZSZmaintaining the substantially rigid relationship between the seat and back-rest.

The second movement guiding linkage includes the link 234 of the front guiding means 232, the portion of the seat 224 intermediate the pivotal connection 24%) and the seat pivot 235? and the portion of the back-rest intermediate the seat pivot 232i) and the pivotal connection 25% as the movable links thereof, with a stationary link being provided intermediate the pivotal mount 235 and the pivotal connection ZSiland with the second holding link 253 keeping the rear guide link 246 effectively rigid with the support.

In this illustrative embodiment, the leg-rest 226 is mounted for movement from the retracted position of FIG. 7 to the elevated leg-supporting positions illustrated in FIGS. 8 and 9 by a leg-rest mounting linkage which includes a hanger arm 2&6 which has a pivotal connection 258 adjacent its lower end to the leg-rest 226. The

hanger arm 266 is suspended from a carrier link 279,

which rests on a stop 272 and has a pivotal mount 274 adjacent its rearward end on'the support; The carrier link 27% is connected to the hanger arm 266 by first and second connecting

links

276, 278; Specifi ally, in the position shown in FIG. 7 the connecting link 2% has a pivotal connection 2% adjacent its lower end on the forward end of the carrier link 27%? and a pivotal connection 282 to the upper end of the hanger arm 266, while the connecting link 278 has a pivotal connection 284 at its lower end to the carrier link 27! at a point spaced from the pivotal connection 28% and a pivotal connection 286 at its upper end to the hanger arm 2:56 at a point spaced from the pivotalconnection 232. The hanger arm 266 of the leg-rest mounting linkage is coupled to the seat 22- of the body-supporting means by a double-arm actuating lever 283 which has a pivotal mount 2% intermediate its ends on the. support, with the upwardly extending arm thereof being coupled to the seat by'a connecting link 292 having a pivotal connection 294 at its forward end to the arm and a pivotal connection at its rearward end to the seat 224 coaxially oi the pivotal connection 269. The other arm of the double-arm lever 28% is coupled to the hanger arm 266 by a connecting link 2% having a pivotal connection 297 at its rearward end to the arm and a pivotal connection 298 at its forward end to the hanger arm 2%. During the first movement phase the carrier link 270 remains stationary relative tothe support such that the pivotal connections 28! 284 of the

links

276, 278 serve as'relatively stationary pivotal mounts for the leg: rest mounting linkage, with the

links

276, 278 turning in the clockwise direction incident to turning movement of the double-arm actuating lever 2%. At the end of the first movement phase, the leg-rest mounting linkage .is blocked by the link 27:: coming into contact with the piv ot 284 serving as a stop and thereby, providing a substantially rigid interconnection between the hanger arm zss and the carrier link 270, with the pivotal mount 274 of the carrierlink serving as-a stationary pivotal mount about-which the leg-rest 226 swings during the second movementphase, as may be appreciated by progressively inspecting FIGS. 8 and 9.

Since the operation of this embodiment is substantially in a sense, functionally replace physical stops.

consideration it might appear that the use of one or more or the other of the movement phases, which holding links, At first stops would be simpler, but it has been found that the provision of such stops in the actual production of hardware for such reclining chairs, which stops are accurately disposed and of sufiicient stren th, is neither chea nor relatively easy to accomplish.

Further, the use of such holding links aifords a certain amount of flexibility in the control linkage, wherein, as previously pointed out, it may be advisable to make small adjustments in the angular relationship between the backrest and seat during the first movement phase to more optimally position the seat and back-rest in relation to each other at the beginning and end of such first movement phase and/or for the purposes of controlling chair balance. Such holding link, having served its intended function in one movement phase, becomes inactive during the other movement phase.

A latitude of modification, change and substitution is tended 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.
