Definitions

  • the usual reclining chair generally features a seat and a back-rest movably mounted on a support frame for movement between an upright sitting position and a rearwardly-inclined reclining position.
  • a leg-rest is conventionally included in the chair structure and is provided with a control and actuating mechanism, generally in the form of a linkage, which is coupled to the seat and/or to the back-rest for coordinated movement of the leg-rest with the seat and back-rest.
  • the leg-rest is normally disposed in a retracted position beneath the front end of the seat when the seat and back-rest are in their upright sitting position, and is then moved by the leg-rest linkage to an extended leg-supporting position forwardly of and substantially at the level of the seat when the seat and backrest are brought to their reclining position.

  • the fully-reclined position the occupant is positioned in an attitude of repose for complete relaxation.
  • Another object of the invention is the provision of a leg-rest control and actuating linkage for a double movement reclining chair of the character described, which is adapted to move the leg-rest to a first extended leg-supporting position in response to movement of the back-rest to its intermediate semi-reclined position, and is also adapted to maintain the leg-rest substantially at the level of the seat when the seat and back-rest are moved to their fully-reclined position.
  • a further object of the invention is the provision of a reclining chair of the character described in which the back-rest and seat control mechanism and leg-rest control mechanism are inter-related for cooperative automatic action in coordinating movement of the leg-rest with movement of the back-rest and seat, and in maintaining the leg-rest at the level of the seat when the latter is inclined in the fully-reclined position of the chair.

(Cl. 297-63) The present invention relates to improvements in reclining chairs and in particular to a new and improved back-rest and seat control structure and a new and improved leg-rest control structure for a reclining chair of the double-movement type.
The usual reclining chair generally features a seat and a back-rest movably mounted on a support frame for movement between an upright sitting position and a rearwardly-inclined reclining position. A leg-rest is conventionally included in the chair structure and is provided with a control and actuating mechanism, generally in the form of a linkage, which is coupled to the seat and/or to the back-rest for coordinated movement of the leg-rest with the seat and back-rest. The leg-rest is normally disposed in a retracted position beneath the front end of the seat when the seat and back-rest are in their upright sitting position, and is then moved by the leg-rest linkage to an extended leg-supporting position forwardly of and substantially at the level of the seat when the seat and backrest are brought to their reclining position.
A recent development in reclining chairs has been the double movement type of chair in which the seat and back-rest are constructed and arranged to be moved through a first motion phase to an intermediate or semireclined position and then to a fully-reclined position. In the intermediate or semi-reclined position the occupant of the chair is supported in a relaxed but still substantially upright attitude in which he may read, view television, or the like, with his legs extended and supported. In the fully-reclined position, the occupant is positioned in an attitude of repose for complete relaxation. In this type of double movement chair, a special leg-rest control linkage is required to bring the leg-rest to its extended position in the intermediate semi-reclined position of the chair, and to maintain the leg-rest extended at the level of the seat in the fully-reclined position of the chair.
It is an object of the present invention to provide a reclining chair of the double movement type which incorporates an improved back-rest and seat control mechanism which will guide the back-rest to a first inclined position relative to the seat in the intermediate or semi-reclined position of the chair, and will then automatically guide the seat to an inclined position and the back-rest to a further inclined position in the fully-inclined position of the chair.
Another object of the invention is the provision of a leg-rest control and actuating linkage for a double movement reclining chair of the character described, which is adapted to move the leg-rest to a first extended leg-supporting position in response to movement of the back-rest to its intermediate semi-reclined position, and is also adapted to maintain the leg-rest substantially at the level of the seat when the seat and back-rest are moved to their fully-reclined position.
A further object of the invention is the provision of a reclining chair of the character described in which the back-rest and seat control mechanism and leg-rest control mechanism are inter-related for cooperative automatic action in coordinating movement of the leg-rest with movement of the back-rest and seat, and in maintaining the leg-rest at the level of the seat when the latter is inclined in the fully-reclined position of the chair.
According to my invention, I provide a reclining chair of the double movement type in which the back-rest is pivotally mounted on the support frame and the seat is mounted for rearward movement by front and rear guiding members. The seat is connected to the back-rest by coupling means providing a lost motion connection in such a manner that when the back-rest is initially pivoted rearwardly from an upright sitting position to an intermediate tilted position, the seat does not move but remains in a level position. At the end of this first motion phase, the lost motion connection engages so that in the further movement of the back-rest through a second motion phase from the semi-reclined position to a fully-reclined position, the back-rest carries the seat rearwardly with it, the seat being guided by the front and rear guiding members to a rearwardly tilted position.
The leg-rest control linkage includes a lever which is pivotally mounted on a portion of the seat and is connected at one end to an actuating link and at the other end through an intermediate linkage to the leg-rest. The
actuating link is connected to the back-rest in such a manner that when the back-rest is tilted rearwardly, the actuating link turns the lever about its pivotal mount on the seat, thereby causing it to raise the leg-rest to its extended leg-supporting position through said intermediate linkage. During the second motion phase, the leg-rest control linkage remains in substantially the same position relative to the seat so that the leg-rest is maintained in extended, legsupporting position at the fully-reclined position of the chair.
The above brief description will be more fully appreciated and additional objects and advantages of the invention will become apparent during the course of the following specification, when taken in conjunction with the accompanying drawings illustrating several illustrative embodiments of the invention, and in which:

FIG. 6 is a side elevational view similar to FIGS. 4 and 5, but showing the chair illustrated therein in its fullyreclined position.
Referring in detail to the drawings, and particularly to FIGS. 1-3, there is shown a reclining chair made in accordance with the present invention, in which the legrest is connected directly to the front end of the seat. The reclining chair, designated generally by the reference numeral 10, includes a support frame 12 having opposed side walls 14 and 16 which are rigidly connected by suitable cross bars or braces 18 and preferably raised above the floor level by depending legs 20 of any suitable type.
A body-supporting structure, which includes a backrest 22 and a seat 24, is movably mounted on the support frame 12 between the side walls 14 and 16. The back-rest 22 is pivotally mounted at its lower end on the support 12 by a pivot 26 so that it may be rearwardly tilted about said pivot 26 to its semi-reclined position shown in FIG. 2, and then further to its fully-reclined position shown in FIG. 3. The seat 24 is connected to the back-rest 22 by coupling means so arranged that the seat is maintained immovable when the back-rest is pivoted rearwardly from the sitting position of FIG. 1 to the intermediate semi-reclined position of FIG. 2, and is then drawn rearwardly with the back-rest when the latter'is pivoted further rearwardly from the semi-reclined position to the fully-reclined pos'iton of FIG. 3.
The seat 24 is movably mounted on the support frame 12 by a pair of guide links 28 and 30. The front guide link 28 is pivotally mounted at 32 on the support frame 12 and its free end is connected by pivot 34 to the seat 24 through a depending plate or extension 36 which is rigidly carried by the seat. The rear guide link is pivotally mounted at 38 on the support frame 12 and its free end is connected by pivot 40 to the rear end of the seat 24.
The coupling means connecting the Seat 24 and backrest 22 comprises a connecting link 42 connected by pivot 44 to the back-rest 22 at a point above the backrest pivot 26. The connecting link 42 is slidably engaged with the rear guide link 30, this slidable engagement being effected by an elongated slot 46 at the free end of the connecting link 42, and a pivot pin 48 rigid with the rear guide link 30 and slidably and rotatably extending through said slot 46.
In the upright sitting position of the chair, shown in FIG. 1, the seat 24 is supported in a substantially level position by a stop member 50, the forward portion of the seat resting upon said stop member 50 and the latter preventing the seat from moving forwardly and downwardly 'under the weight of the occupant. The front and rear guide link-s 28 and 30 are forwardly inclined from their respective pivotal mounts 32 and 38, and the pin 48 is located at the rear end of the slot 46.
When the occupant of the chair wishes to move to a more relaxed position, he shifts his weight rearwardly and applies rearward pressure against the back-rest 22. This will cause the back-rest 22 to pivot about its pivotal mount 26, the connecting link 42 being drawn rearwardly with the back-rest 22 and the slot 46 moving rearwardly relative to the pivot pin 48. Because of the sliding engagement of the pin '48 With the slot 46, the rear guide link 30 is not moved. Thus, during this first motion phase, the back-rest 22 pivots rearwardly to the intermediate semi-reclined position of FIG. 2, while the seat 24 remains stationary and in its level position.
' The first motion phase is ended upon engagement of the'pin 48 with the forward end of the slot 46, and the chair is now located in the intermediate semi-reclined position of FIG. 2 in which the occupants body is still in .a substantially upright, but more relaxed position, with the leg-rest in its extended leg-supporting position, as will be presently explained. This semi-reclined posiiton is suitable for comfortable reading, television viewing, sewing, or the likev If the occupant then wishes to'recline in' a completely relaxed position, he applies further rearward body pressure against the back-rest 22,
causing the chair parts to move through a second motion phase to a fully-reclined position, shown in' FIG. 3.
' During the second motion phase, the connecting link 42, through its slot 46, exerts a rearward pulling force on the'rear gmide link 30, causing the same to turn rearwardly about its pivotal mount 38 and thus to move the seat 24 rearwardly in response to the rearward pivotal movement of the hack-rest 22. As the seat 24 moves rearwardly it causes the front guide link 28 to turn rearwardly on its pivotal mount 32. As a result, the seat 24, during the second motion phase, moves rearwardly with the back-rest 22, and is guided in its rearward movement by both the front and rear guide links 28 and 39 which pivot simultaneously. It will be appreciated that in the preferred embodiment of the invention shown herein, the seat is coupled to the backrest through the connecting link 42, the pin and slot connection 46, 48 and the rear guide link 30. As an obvious alternative, the connecting link 42 may be connected directly to the seat 24 by a pin and slot connection, the rear guide link 30 in this instance serving only to guide the movement of the rear of the seat.
It will be noted that the front guide link 28 is substantially longer than the rear guide link 39. Thus, when the seat 24 is drawn rearwardly during the second motion phase, and the guide links 28 and 30 pivot upwardly, the seat pivot 34 at the end of the front guide link 28 moves vertically a relatively long distance while the seat pivot 4i) at the end of the rear guide link moves vertically a relatively short distance. This has the effect of providing a compound movement for the seat 24 during the second motion phase, in which the front end of the seat is raised relative to the rear end thereof, and the seat is disposed at a rearward inclination in the fullyreclined position of FIG. 3.
The second motion phase is halted in the fully-reclined position of the chair by engagement of a movable portion of the structure with suitably positioned stop means, such stop means being customary and well-known in conventional reclining chairs. For example, in the embodirnent illustrated herein, the upper edge 52 of the rear leg 20 is positioned to engage the lower rear portion of the back-rest 22 and block further rearward pivotal movement thereof, as shown in FIG. 3.
As was previously described, the back-rest 22, in the first motion phase, moves rearwardly relative to the stationary seat 24, As a consequence, a gap or space will be formed between the rear end of the seat and the adjacent surface of the back-rest which gap will be greatest at the semi-reclined position of the structure. The presence of such a gap is undesirable both from the standpoint of comfort and appearance. To avoid the formation of such a gap, the back-rest 22 may be formed with a forwardly-projecting extension portion 54 in alignment with the rear of the seat 24, and the rear end of the seat may be provided with a pocket or recess 56 sized to receive the extension portion 54. The recess 56 is shaped to allow movement of the back-rest extension portion 54 therein, so that throughout the movement of the chair parts, the body-supporting surfaces of the seat and backrest are contiguous and unbroken.
The chair of FIGS. 1-3 also includes a leg-rest 6t) and a leg-rest control linkage mounted for coordinated movement with the back-rest 22 for raising the leg-rest 60 during the first motion phase from the retracted position beneath the seat 24, shown in FIG. 1, to the extended position of FIG. 2, in which it is located forwardly of and substantially at the level of the front of the seat.
In the embodiment of FIGS. 1-3, the leg-rest 69 is rigidly carried by a hanger arm or bar 62, the freeend of which is mounted by pivot 64 on the front end portion of the seat 24. The leg-rest control linkage comprises an actuating link 66, a driven link 68 and an intermediate link or lever 70. The lever 70 is connected intermediate its ends by pivot 72 to the depending extension plate 36 of the seat 24, so that the lever 70 may be said to be pivotally mounted on the seat. The upper arm 74 of the lever 70 is connected .by'pivot 76 to the rear end of the driven link 63, the front end of the latter being connected by pivot '78 to an intermediate point on the hanger arm 62. The lower lever arm 80 is connected by pivot 82 to the front end of the actuating link 66, the rear end of which is connected by pivot 84 to a point on the back-rest 22 located above the back-rest pivot 26.
When the back-rest 22 is pivoted rearwardly during the first motion phase, the pivotal mount 72 of the lever 79 is stationary because the seat 24 does not move. The
back-rest 22 carries the actuating link 66 rearwardly with it, causing the latter to pull rearwardly upon the lever lower arm 80 and thereby causing the lever to turn in a counter-clockwise direction (as viewed in FIGS. 1 and 2) about its stationary pivot mount 72. The lever upper arm 74 therefore moves in a forward direction, thrusting the driven link 68 forwardly to raise the leg-rest 60 to its extended position. It will be observed that the upper lever arm 74 is appreciably longer than the lower lever arm 80. Hence the driven link 68 is provided with an amplified linear movement in response to a relatively short movement of the back-rest sufficient to raise the leg-rest to its extended position of FIG. 2.
During the second motion phase of the chair to its fully-reclined position, the seat 24 moves rearwardly with the back-rest 22, and thus the seat extension plate 36, lever 70, and the lever mount 72 move rearwardly with the actuating link 66. The actuating link 66 therefore ceases to apply a rearward pulling force on the lower lever arm 80, but rather the leg-rest 6t and the entire leg-rest control linkage moves upwardly as a unit with the forward end of the seat. The leg-rest 60 is thus maintained throughout the second motion phase in a substantially constant relationship with the forward end of the seat.
To bring the chair parts from the fully-reclined position of FIG. 3 back to the semi-reclined position in FIG. 2, the occupants need only shift his weight forwardly on the seat 24, and the latter will be guided forwardly on the front and rear guide links 28 and 30 until it engages the stop member 50 in the intermediate semi-reclined position. To bring the chair structure from the semireclined position of FIG. 2 to the upright position of FIG. 1, the occupant presses downwardly with his legs upon the leg-rest 60, causing the leg-rest to move downwardly to its retracted position and simultaneously causing a forward pivoting of the back-rest 22 through the leg-rest control linkage.
In FIGS. 46 there is shown a modified form of reclining chair to illustrate that the seat and back-rest control mechanism and the leg-rest control mechanism may be used with alternate types of leg-rest guiding structures. The chair in FIGS. 46 is identical in structure to that illustrated in FIGS. l-3 except for the legrest guiding linkage, and like parts are given corresponding reference numerals which are part of a 100 series. The reclining chair, designated generally by the reference numeral 110, again includes a support frame 112 having opposed side walls 114 and 116 connected by cross bars 118 and supported by depending legs 120.
The body-supporting structure, comprising a back-rest 122 and a seat 124, is movably mounted on the support frame 112 between the sidewalls 114 and 116. The lower end of back-rest 122 is pivotally mounted at 126 on the support frame 112 for rearwardly tilting movement to its semi-reclined position shown in FIG. 5, and then fur ther to its fully-reclined position shown in FIG. 6. The seat 124 is again provided with lost motion coupling means so arranged that the seat is maintained in a stationary level position when the back-rest is pivoted rearwardly from the sitting position of FIG. 4 to the intermediate semi-reclined position of FIG. 5, and is then drawn rearwardly with the back-rest when the latter is pivoted further rearwardly from the semi-reclined position to the fully-reclined position of FIG. 6.
For movably mounting the seat 124 on the support frame 112, the front guide link 128 is pivotally mounted at 132 on the support frame 112 and its free end is connected by pivot 134 to the seat 124 through a depending plate or extension 136 which is rigidly carried by the seat. The rear guide link 1130 is pivotally mounted at 138 on the support frame 112 and its free end is connected by pivot 140 to the rear end of the seat 124.
The coupling means connecting the seat 124 and backrest 122 again comprises a connecting link 142 connected by pivot 144 to the back-rest 122 at a point above the 6 back-rest pivot 126. The connecting link 142 is slidably and pivotally connected to the rear guide link 130 by a pin and slot connection comprising an elongated slot 146 at the free end of the connecting link 142, and a pivot pin 148 rigid with the rear guide link 130 and slidably and rotatably extending through said slot 146.
In the upright sitting position of the chair 110, shown in FIG. 4, the seat 124 is supported in its substantially level position by engagement of the forward portion of the seat with a fixed stop member 150. The front and rear guide links 128 and 130 are forwardly inclined from their respective pivotal mounts 132 and 138, and the pin 148 is located at the rear end of the slot 146.
The operation of the seat and back-rest of the chair is identical to that of the chair 10 shown in FIGS. 1-3 and previously described, hence a detailed description of such operation will not be repeated. In general, it will be understood that in the first movement phase, the backrest 122 pivots rearwardly about its pivotal mount 126 and the lost motion movement of the pin and slot 148, 146 maintains the seat immovably in its level sitting position, in the manner previously explained. The first motion phase is ended upon engagement of the pin 148 with the forward end of the slot 146, and the chair is then located in the intermediate semi-reclined position of FIG. 5 in which the occupants body is still in a substantially upright, but more relaxed position, with the leg-rest in its extended leg-supporting position.
During the second motion phase, the pin 148 and slot 146 are in non-slidable engagement, as shown in FIGS. 5 and 6, and the connecting link 142 exerts a rearward pulling force on the rear guide link 130, causing the seat 124 to move rearwardly in response to the rearward pivotal movement of the back-rest 122. As the seat 124 moves rearwardly during the second motion phase, it is guided in its rearward movement by both the front and rear guide links 128 and pivoting simultaneously.
During the second motion phase, the guide links 128 and 138 pivot upwardly and rearwardly, and because the front guide link 128 is longer than the rear guide link 130, the seat 124 is guided in a compound movement in which its front end is raised relative to the rear end thereof. Movement of the seat and back-rest in the second motion phase is halted by engagement of the lower portion of the back-rest 122 with the upper surface 152 of the rear leg 120.
The chair shown in FIGS. 4-6 also includes a leg-rest and a leg-rest control linkage for coordinating movement of the leg-rest with pivoting movement of the backrest 122. In this instance, however, the leg-rest is not pivotally mounted directly on the seat, as in the embodiment of FIGS. 13, previously described, but is rather carried by a guiding linkage which is mounted on the seat. The leg-rest 160 is supported by a pair of rearwardlyextending links and 186 which are connected at spaced points on the leg-rest 160 by respective pivots 187 and 1-88. The leg-rest guiding linkage also includes a pair of depending links 189 and 190 which have respective pivotal mounts 191 and 192 at spaced points on the forward portion of the seat 124. The links 185 and 189 are connected in end-to-end relationship by pivot 193, while the links 186 and 190 are connected end-to-end by a pivot 194. The rearwardly-extending link 186 crosses over the front depending link 189 and is pivotally connected thereto at the crossing-over point 195.
The leg-rest control linkage again comprises an actuating link 166, a driven link 168 and a lever 170, the latter being mounted intermediate its ends on the depending plate 136 of seat 124 by a pivot 134. The actuating link 166 is connected at one end to the short arm 1-80 of the lever 170 by pivot 182, and at the other end by pivot 184 to the back-rest 122 at a point above the back-rest pivot 126. One end of the driven link 168 is connected by pivot 176 to the long lever arm 174, While the other end a is connected by pivot 196 to an intermediate point on the front depending link 189.
When the back-rest 122 is pivoted rearwardly during the first motion phase, the actuating link 166 moves rearwardly causing the lever 179 to turn about its temporarily stationary pivot 172 and move the driven link 168 forwardly. The driven link 16% in turn raises the front depending link 189, to move the leg-rest 160 from its retracted position of FIG. 4 to its extended, leg-supporting position of FIG. 5.
The leg-rest guiding linkage forms an interconnected double four-bar linkage supporting and guiding the movement of the le -rest 160 and effective to position the legrest further forwardly of the front end of the seat in its extended position, for supporting the legs of tall persons. One four bar linkage is formed by the link 190, the portion of link 189 between pivots 191 and 195, the portion of the link 186 between pivots 194 and 195, and the portion of the seat 124 between pivots 191 and 192. The other four bar linkage is formed by link 185, the portion of link 186 between pivots 188 and 195, the portion of link 189 between pivots 193 and 195, and the portion of the leg-rest 166} between pivots 187 and 188.
When the front depending link 189 is thrust forwardly by the driven link 168, the double four-bar linkage construction is effective to thrust the leg-rest 160 outwardly from the front of the seat 124 to a greater degree than in the arrangement of FIGS. l-3 wherein the leg-rest is hinged directly to the seat. In the second motion phase, the leg- rest control linkage 166, 168 and 170 maintains the leg-rest in its extended leg-supporting position as shown in FIG. 6, and as previously described.
While preferred embodiments of the invention have been illustrated anddescribed herein, it is obvious that numerous additions, changes and omissions may be made in such embodiments without departing from the spirit and scope thereof.
