Filed May 21, 1959, Ser. No. 814,833 9 Ciaims. (til. 297-89) The present invention relates generally to reclining chairs, and in particular to improved leg-rest mounting and controlling arrangements for such reclining chairs.

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 disposed beneath the seat and mounted for movement into an elevated leg-supporting position. Provision is made for moving the leg-rest from beneath the seat to the elevated leg-supporting position in response to the movement of the body-supporting means of the chair. Of recent times and with the tendency towards more modern and streamlined furniture, there has developed the need for reclining chairs wherein the chair support or frame is disposed above the level of the floor by depending legs, with the leg-rest being stored in a folded-back position within the vertical extent of and substantially hidden from view by such chair frame. With the leg-rest thus hidden from view, it is possible to style such reclining chairs to have the appearance of other pieces of the highleg modern design such that the reclining chair may be used in modern furniture groupings.

Broadly, it is an object of the present invention to provide an improved leg-rest mounting and controlling arrangement for a reclining chair which realizes one or more of the aforesaid objectives. Specifically, it is within the contemplation of the present invention to provide an improved and simplified leg-rest mounting and control arrangement for coordinating the elevation of the leg-rest of the reclining chair to the movement of the body-supporting means thereof. Advantageously, my improved leg-rest mounting and control arrangement finds application in reclining chairs of the type incorporating a unitary seat and back-rest unit of a high-leg modern styling.

In accordance with an illustrative embodiment demonstrating objects, features and advantages of the present invention there is provided a reclining chair of the type which includes a support, body-supporting means including a seat and back-rest and means including a guiding link pivotally connected to the support and to the seat for mounting the body-supporting means for movement relative to the support. A leg-rest is disposed beneath the seat and a leg-rest mounting and control arrangement is operatively connected to the leg-rest and to the body-supporting means with such arrangement comprising a first link pair including first and second links which are pivotally interconnected with the first link being pivotally mounted on the seat and the second link being pivotally connected, directly or indirectly, to the leg-rest. The arrangement further comprises a second link pair including third and fourth links which are pivotally interconnected, with the third link pivotally mounted on the guiding link and the fourth link being pivotally connected, directly or indirectly, to the leg-rest. Provision is made for coordinating the first and second link pairs as by a pivotal connection between one link of the first link pair and one link of the second link pair. A direct actuating link is pivotally mounted on the support and pivotally connected to one of the first and third links whereby in response to rearward movement of the seat relative to the support, the leg-rest is moved into successive elevated leg-supporting positions. With the described leg-rest mounting and controlling arrangement, the movement of the leg-rest is a function of the movement of the seat of the body-supates tent f 3,58,775 Patented Get. 16, 1962 ice porting means and of the movement of the guiding link of the mounting arrangement for the body-supporting means such that there are two controllable parameters for the operation of the leg-rest.

In response to the rearward tilting movement of the back-rest 26, the front guiding link 30 is effective to guide the forward portion of the seat 28 upwardly and rearwardly while the rear guiding link 32 is effective to guide the rearward portion of the seat 28 rearwardly and downwardly such that the unit may be moved from the upright or sitting position of FIG. 1 to the tilted back resting position of FIG. 2.

Disposed beneath the forward portion of the seat 28 is a leg-rest 42 which is mounted for movement from a stored or retracted position extending substantially horizontally and substantially within the vertical extent of the side panels 22 to an extended and elevated leg-supporting position spaced forwardly of the seat as shown in FIG. 2, with the leg-rest 42 moving substantially through 180 from the retracted position to the extended position. The leg-rest 42 is mounted for movement under control of the tilting movement of the body-supporting unit 24 by a leg-rest mounting and controlling linkage, generally designated by the reference numeral 44, which linkage comprises a first link pair including pivotally connected first and second links 46, 48 and a second link pair including pivotally connected third and fourth links 50, 52. The adjacent ends of the links 46, 48 of the first link pair are pivotally connected at a pivotal connection 54 while the adjacent ends of the links 50, 52 of the second link pair are pivotally connected at a pivotal connection 56. The link 46 of the first link pair has a pivotal mount 58 on the seat adjacent the forward end thereof, while the link 48 of the first link pair has a direct pivotal connection 64 to the leg-rest in this illustrative form of the invention. The link 50 of the second link pair has a pivotal mount 62 on the front guiding link 30 of the main guiding link- ;age, with the pivotal connection 62 being spaced from the pivotal connection 36 of the front guiding link 30 to the seat 28. The link 52 of the second link pair crosses over the link 46 of the first link pair and at the cross over point has a pivotal connection 64 which serves to coordinate the respective first and second link pairs, with the link 52 having a pivotal connection 66 at its forward end to the leg-rest 42 with the pivotal connection 66 being spaced from the pivotal connection 60.

Operatively connected between the extensible leg-rest mounting linkage thus described and the chair frame or support is a direct actuating link 68 which has a pivotal mount 70 on the side panel 22 of the chair frame or support 12 and has a pivotal connection 72 to the link 50 of the second link pair 50, 52, with the pivotal connection 72 being spaced from the pivotal mount 62 of the link 50 on the front guiding link 30.

A typical sequence of operations will now be described to facilitate a more thorough understanding of the pres ent invention: 1 i

' When the chair occupant is seated and leans against the back-rest 26 of the body-supporting unit 24, the bodysupporting unit tilts as a function of the design of the four-bar main guiding or mounting linkage. In response to the rearward tilting movement of the body-supporting unit 24, the pivotal mount 58 of the first link pair 46, 48 of the leg-rest mounting linkage moves upwardly and rearwardly along a path established by the design of the main guiding linkage; simultaneously the pivotal mount 62 of the second link pair 50, 52 of the leg-rest mounting linkage moves rearwardly and upwardly along a path established by the pivotally-mounted front guiding link 30, with the direct actuating link 68 causing the link 50 to turn about the pivotal mount 62 such that the legrest 42 is swung from the retracted position shown in FIG. 1 through a downward arc and then through an upward arc to the elevated leg-supporting position shown in FIG. 2. The final tilted back or reclining position may be established by the provision of an appropriate stop associated with any one of the links, for example, the stop 74 arranged to abut the rear guiding link 32 in the desired tilted position. When the chair occupant desires to restore the chair to the upright sitting position, the occupant merely presses against the leg-rest 42 which causes the chair to move from the tilted position shown in FIG. 2 to the upright sitting position of FIG. 1.

Referring now specifically to the drawings, there is shown in FIGS. 3 and 4 an improved reclining chair demonstrating features of the present invention, generally designated by the reference numeral 110, which includes a support or chair frame 112 having opposite side frames 114- interconnected by appropriate cross braces, the adjacent side having been removed for clarity to expose the operating linkage at such adjacent side of the chair.

.serve as the stationary link thereof. In response to the rearward tilting movement of the back-rest the front guiding link 130 is effective to guide the forward portion of the seat upwardly and rearwardly while the rear guiding link 132 is effective to guide the forward portion of the seat upwardly and rearwardly while the rear guiding link 132 is effective to guide the rearward portion of the seat rearwardly and downwardly such that the unit may be moved from the upright or sitting position in FIG. 3 to the tilted-back resting position of FIG. 4.

Disposed beneath the forward portion of the seat 128 is a leg-rest 142 which is mounted for movement from a stored or retracted position extending substantially horizontally and substantially within the vertical extent of the side panels 122 to an extended and elevated leg-supporting position spaced forwardly of the seat as shown in FIG. 4, with the leg-rest moving substantially through 180 from the retracted position to the extended position. The legrest 142 is mounted for elevation under the control of the tilting movement of the body-supporting unit 124 by a leg-rest mounting and controlling linkage, generally designated by the reference numeral 144, which linkage comprises a first link pair including pivotally connected first and second links 146, 148 and a second link pair including pivotally connected links 150, 152. The adjacent ends of the links 146, 148 of the first link pair are pivotally connected at a pivotal connection 154, while the adjacent ends of the links 150, 152 of the second link pair are pivotally connected at a pivotal connection 156. The link 146 of the first link pair has a pivotal mount 158 on the seat adjacent the forward end thereof, while the link 148 of the first link pair has a direct pivotal connection 160 to the leg-rest. The third link of the second link pair has a pivotal mount 162 on the front guiding link 131' of the main guiding linkage, with the pivotal connection 162 being spaced from the pivotal connection 136 of the front guiding link list to the seat 128. The link 152 of the second link pair crosses over the link 1146 of the first link pair and at the cross over point has a pivotal connection 164 which serves to coordinate the respective first and second link pairs, with the link 152 having a pivotal connection 166 at its forward end to the leg-rest with the pivotal connection 166 being spaced from the pivotal connection 16% Operatively connected between the mounting linkage thus described and the chair frame or support is a direct actuating link 163 which has a pivotal mount 17% on the side panel 122 of the chain frame or support 122 and in this embodiment has a pivotal connection 172 to the link 146 of the first link pair 148, 148, with the pivotal connection 172 being spaced from the pivotal mount 3 .58 of the link 146 on the seat 128.

A typical sequence of operations will now be described to facilitate a more thorough understanding of the present invention:

When the chair occupant is seated and leans against the back-rest 126 of the body-supporting unit 124, the body-supporting unit moves as a function of the design of the four-bar main guiding or mounting linkage. In re sponse to the rearward tilting movement of the body supporting unit 124, the pivotal mount 158 of the first link pair 146, 148 of the leg-rest mounting linkage moves upwardly and rearwardly along a path established by the design of the main guiding linkage; simultaneously the pivotal mount 162 of the second link pair 150, 152, of the leg-rest mounting linkage moves rearwardly and upwardly along a path established by the pivotally mounted front guiding link 139, with the direct actuating link 168 causing the link 146 to turn about the pivotal mount 15% such that the leg-rest 142 is swung from the retracted position shown in FIG. 3 through a downward arc and then through an upward arc to the elevated leg-supporting position shown in FIG. 4. The final tilted back or reclining position may be established by the provision of an appropriate stop associated with any one of the links for example, the stop 174 arranged to abut the front guiding link 130 in the desired tilted position.

Referring now specifically to the drawings, there is shown in FIGS. 5 and 6 an improved reclining chair demonstrating features of the present invention, generally designated by the reference numeral 219, which includes a support or chair frame 212 having opposite side frames 214 interconnected by appropriate cross braces, the adjacent side having been removed for clarity to expose the operating linkage at such adjacent side of the chair.

A typical sequence of operations will now be described to facilitate a more thorough understanding of the present invention:

When the chair occupant is seated and leans against the back-rest 226 of the body-supporting unit 224, the body-supporting unit tilts as a function of the design of the four-bar main guiding or mounting linkage. In response to the rearward tilting movement of the bodysupporting unit 224, the pivotal mount 258 of the first link pair 246, 248 of the leg-rest mounting linkage moves upwardly and rearwardly along a path established by the pivotally mounted front guiding link 230; simultaneously the pivotal mount 262 of the second link pair 256, 252, of the leg-rest mounting linkage moves rearwardly and upwardly along a path established by the design of the main guiding linkage, with the direct actuating link 268 causing the link 25% to turn about the pivotal mount 262 such that the legrest 242 is swung from the retracted position shown in PEG. 5 through a downward arc and then through an upward arc to the elevated leg-supporting position shown in FIG. 6. The final tilted back or reclining position may be established by the provision of an appropriate stop associated with any one of the links,

'2 for example the stop 274 arranged to abut the rear guiding link 232 in the position.

Referring now specifically to FIGS. 7 and 8 there is shown a still further improved reclining chair of the type including a movable seat and movable back-rest demonstrating features of the present invention, generally designated by the reference numeral 310, which includes a support or chair frame 312 having opposite side frames 314 interconnected by appropriate cross braces, the adjacent side having been removed for clarity to expose the operating linkage at such adjacent side of the chair. The chair side frames 314 are seen to be of modern appearance including front and rear legs 3'16, 318 interconnected by an arm rest 320 and a side brace panel 322.

Interposed between the side frames 314 is a split or two-part body-supporting unit 324 which includes a backrest 326 and a seat 323 mounted on the chair support or frame 312 for reclining and inclining movements respectively relative to the support into various reclining positions, such as shown in FIG. 8. The body-suporting unit 324 is mounted between the side frames 314 by a main guiding or mounting linkage which includes a front guiding link 33% and a rear guiding link 332. The front guiding link 33% which is inclined upwardly and forwardly from its lower end to its upper end has a front pivotal mount 334 on the side panel 322 of the chair frame 312 and a front pivotal connection 335 at its upper end to the seat 323 of the body-supporting unit 32-4. The rear guiding link 332 which is disposed substantially vertically in the sitting position of the chair has a rear pivotal mount 338 at its lower end on the side panel 322 of the chair frame 312 and is rigidly connected at its upper end to the lower end of the back-rest 326. The seat 328 is mounted by a rearwardly directed hanger 33 at a seat pivot 34f spaced above the rear pivotal mount 338 which serves as a back-rest pivot. The front guiding link 330, the rear guiding link 332 and the portion of the seat 328 intermediate the pivotal connections 336, 344) serve as the movabie links of the main guiding linkage while the portion of the support intermediate the pivotal mounts 334, 338 serve as the stationary link thereof. In response to the reclining movement of the back-rest 326, the front guiding link 33% is effective to guide the forward portion of the seat 323 upwardly and rearwardly while the rear guiding link 332 is effective to guide the rearward portion 7 of the seat 328 rearwardly and downwardly, such that the seat 328 is inclined and the body-support unit may be moved from the upright or sitting position of FIG. 7 to the reclining position of FIG. 8.

Disposed beneath the forward portion of the seat 328 is a leg-rest 342 which is mounted for movement from a stored or retracted position extending substantially horizontally and substantially within the vertical extent of the side panels 322 to an extended and elevated leg-supporting position spaced forwardly of the seat as shown in FIG. 8, with the leg-rest 342 moving substantially through 180 from the retracted position to the extended position. The leg-rest 342 is mounted for movement under control of the movement of the body-supporting unit 32 by a legrest mounting and controlling linkage, generally designated by the reference numeral 344, which linkage comprises a first link pair including pivotally connected first and second links 346, 348 and a second link pair including pivotally connected third and fourth links 350, 352.

A typical sequence of operations will now be described to facilitate a more thorough understanding of the present invention:

When the chair occupant is seated and leans against the back-rest 326 of the body-supporting unit 324, the seat 328 is inclined as a function of the design of the four-bar main guiding or mounting linkage. In response to the inclining movement of the seat 323, the pivotal mount 35% of the first link pair 34-6, 346 of the leg-rest mounting linkage moves upwardly and rearwar ly along a path established by the design of the main guiding linkage; simultaneously the pivotal mount 362 of the second link pair 354 332 of the leg-rest mounting linkage moves rearwardly and upwardly along a path established by the pivotally-mounted front guiding link 330, with the direct actuating link 35% causing the link 35? to turn about the pivtal mount 362 such that the leg-rest 34-2 is swung from the retracted position shown in PEG. 7 through a downward arc and then through an upward arc to the elevated leg-supporting position shown in FIG. 8. The final tilted back or reclining position may be established by the provision of an appropriate stop associated with any one of the links, for example the stop 374 arranged to abut the rear guiding link 332 in the desired reclining position. When the chair occupant desires to restore the chair to the upright sitting position, the occupant merely presses against the leg-rest 342 which causes the chair to move from the reclining position shown in FIG. 8 to the upright sitting position of FIG. 7.

A latitude of modification, change and substitution is intended in the foregoing disclosure and in some instances some feature 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.
