United States Patent 3,132,894 RECLINER CHAR OF THE MULTIPLE POSITION TYPE IN CORPORATING IMPROVED HEAD- REST CONTROL Fridtjof F. Schliephacke, Berlin-Schmargendorf, Germany, assignor to Anton Lorenz, Ocean Ridge, Boynton Beach, Fla.

Filed Aug. 30, 1960, Ser. No. 52,943 3 Claims. (Cl. 297-61) The present invention relates generally to reclining chairs of the multiple movement type, and in particular to an improved head-rest and mounting and control arrangement for such reclining chairs.

The recently developed multiple movement chair comprises a support and body-supporting means including a seat and back-rest which is mounted on the support for movement from a sitting position to an intermediate, tilted sitting position during a first movement phase and for movement from the intermediate, tilted sitting position to a reclining position during a second movement phase. Such chairmay be of the reclining type including a movable seat and a movable back-rest in which the seat and back-rest move with substantially no change in their angular relationship during the first movement phase and move with an increase in the angular relationship therebetween during the second movement phase; or may be of the rester type including a rigid seat and back-rest in which there is no change in the angular relationship between the seat and back-rest during either of the movement phases. Such multiple movement chairs of the recliner or rester type usually incorporate a leg-rest which is mounted for movement into a substantially elevated leg-supporting position during the first movement phase such as to provide an adequate leg-support for the chair occupant in the intermediate, tilted sitting position and in the infinite number of reclining positions during the second movement phase. Further, such multiple movement chairs may incorporate a head-rest which is mounted for movement on the back-rest from a stored position to an extended head-supporting position during the first movement phase such as to provide an adequate head-support for the chair occupant in the intermediate, tilted sitting position and in the infinite number of reclining positions during the second movement phase. The incorporation of the head-rest in the chair facilitates modern styling, enabling the comfort requirements to be realized in a chair having a relatively low back.

Broadly, it is an object of the present invention to provide an improved head-rest and mounting and control arrangement adapted to be incorporated into a multiple movement chair of the recliner or rester type. Specifically, it is within the contemplation of the present invention to provide a head-rest which is moved to an extended head-supporting position in response to the first movement phase of the multiple movement chair of the recliner type such that during the second movement phase, as the angle between the seat and back-rest progressively opens up, the head-rest is in its head-supporting position and remains stationary relative to the back-rest for the head-supporting function.

It is a further object of the present invention to pro vide an improved mounting arrangement for movably mounting a head-rest on a back-rest for movement between a stored position within the outline of the backrest to an extended head-supporting position spaced above and forwardly of the back-rest.

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 movement from a sitting position to an intermediate, tilted sitting position during a first movement phase and from the intermediate, tilted sitting position to a reclining posiion during a second movement phase, and coordinating means operatively connected to the bodysupporting means and mounted on the support for establishing the first and second movement phases which coordinating means includes a pivotal mount on the support about which the seat turns during the second movement phase. A head-rest is mounted on the back-rest for movement from a stored position to an extended head-supporting position during the first movement phase, and actuating means are operatively connected to the mounting means for the head-rest, to the body-supporting means and to the support for moving the headrest to the extended supporting position during the first movement phase of the chair. The actuating means includes a displaceable pivot on the body-supporting means which is movable relative to the pivotal mount during the first movement phase and is movable substantially in an are about said pivotal mount during the second movement phase. The relative movement of the displaceable pivot causes a movement of the headrest to the extended supporting position during the first movement phase; and the arcuate movement of the displaceable pivot maintains the head-rest substantially in the head-supporting position during the second movement phase.

In accordance with further features of the present invention, the mounting means for the head-rest includes a first mounting link which is pivotally mounted on the back-rest at a first pivotal mount and pivotally connected to a head-rest at a first pivotal connection and a mounting link pair which includes second and third mounting links which are pivotally interconnected. Provision is made for pivotally mounting the second mounting link on the back-rest at a second pivotal mount spaced from the first pivotal mount and for pivotally connecting the third mounting link to the head-rest at a second pivotal connection at a point spaced from the first pivotal connection. By appropriately proportioning and arranging the several mounting links, it is possible to establish varying paths of movement for the head-rest and to orient the head-rest in a wide variety of head-supporting positions relative to the back-rest wherein the head-rest remains during the second movement phase.

The above brief description as well as further objects, features and advantages of the present invention will now be described by reference to the following detailed description of a presently preferred, but nonetheless illus trative, embodiment according to the present invention, when taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a side elevational view of a typical multiple movement recliner type chair incorporating an improved head-rest and mounting and control arrangement in accordance with the present invention, the head-rest being shown in its retracted or stored position and the chair being shown in its sitting position;

FIG. 2 is a side elevational view similar to FIG. 1 but with the portions of the frame removed in the interest of clarity, the head-rest being shown in its extended head-supporting position and the chair being shown in an intermediate, tilted sitting position; and

FIG. 3 is a side elevational view similar to FIG. 2, showing the head-rest remaining in its extended headsupporting position, the chair having moved through the second movement phase into a fully reclined position.

Referring now specifically to the drawings, there is shown a reclining chair 10 which embodies an improved head-rest and control arrangement in accordance with the present invention. The chair 10 is constructed in accordance with the teachings of US. Patent No. 3,065,026, filed on July 20, 1960, now Patent No. 3,065,026, granted November 20, 1962, and entitled Reclining Chair of the Multiple Position Type, and includes a chair frame or support 12 having

opposite side walls

14, 16 interconnected by appropriate cross braces 18 and supported on depending legs 20. A body-supporting unit or means including a back-rest 22 and a seat 24 are mounted on the support for reclining and inclining movement respectively through a first movement from the upright sitting position illustrated in FIG. 1 to the intermediate, tilted sitting position illustrated in FIG. 2 and for a second movement phase from the intermediate, tilted sitting position illustrated in FIG. 2 through a series of reclining positions to the fully reclined po sition illustrated in FIG. 3. Although, the back-rest is adapted for movement relative to the seat during the second movement phase, it will be appreciated that the invention herein finds application in rester type chairs including a unitary body-support means. In the interest of simplicity there is no showing the'leg-rest and its mounting arrangement which is usually found in reclining chairs of this type.

The back-rest 22 is mounted on the seat 2-4 at a backrest pivot 26 which back-rest pivot is provided intermediate the seat and an elongated back-rest bracket 28 which is secured to the lower end of the back-rest 22 and extends fore and aft of the chair. Extending from the front to the rear of the chair frame or support 12 is a first carrier member 30 which rests adjacent its front end on an adjacent and underlying cross brace 18 and has a first carrier pivot 32 at its rearward end on the support provided by an appropriate mounting bracket 34. During the first movement phase, the first carrier member 30 remains stationary and rests against the underlying cross brace 18, as may be appreciated by progressively inspecting FIGS. 1 and 2; and during the second movement phase the first carrier member 30 turns in the clockwise direction about the first carrier pivot 32 and through an ascending arc, as may be appreciated by progressively inspecting FIGS. 2 and 3.

Seat guiding means are operatively connected between the first carrier member 30 and the seat 24 for imparting a first inclination to the seat 24 during the first movement phase, as may be seen in FIGS. '1 and 2. The seat guiding means includes a front seat guiding link 36 which is upwardly and forwardly inclined from its lower end to its upper end. The lower end of the front seat guiding link 36 has a front pivotal mount 38 on the forward end of the first carrier member 30, while the upper end of the front seat guiding link 36 has a front pivotal connection 4th to the seat 24. Disposed rearwardly of the front seat guiding link 36 and substantially parallel thereto is a rear seat guiding link 4-2 which has a rear pivotal mount 44 at its lower end on the first carrier member 30 at a point spaced rearwardly of the front pivotal mount 68 and a rear pivotal connection 46 to the seat 24 at a point spaced rearwardly of the front pivotal connection 4-0. The front and rear

gear guiding link

36, 42 and the relatively stationary first carrier member 30 will be recognized as providing a four-bar seat guiding linkage which is operative during the first movement phase to guide the seat 24 reaiwardly relative to the support to an inclined position, with the first carrier member remaining stationary during such first'movement phase.

Provision is made for blocking movement of the seat guiding means relative to the first carrier member 3% at the end of the first movement phase such that the carrier member 30, the seat guiding means, and the seat 24 become a unitary assembly which turns about the first carrier pivot 32 during the second movement phase. The blocking means is in the form of a stop 43 which is fixed to the carrier member 30 rearwardly of the front guiding link 36 and in position to abut the same in the intermediate, tilted sitting position illustrated in FIG. 2.

The coordinating or guiding linkage for the chair is completed by the provision of a second carrier member 50 which is disposed abovethe first carrier member 30 and extends from front of the chair frame or support to a location rearwardly of the first carrier pivot 32. At its rearward end the second carrier member 54 has a second carrier pivot 52 on the support provided by an appropriate mounting bracket 54 which second carrier pivot 52 is spaced rearwardly of the first carrier pivot 32. Means are provided for connecting the second carrier member 50 to the back-rest 22 which means is arranged in relation to the seat guiding means for guiding the backrest 22 to a first reclined position during the first movement phase, with the second carrier member 50 remaining stationary. The connecting or coupling means includes a back-rest connecting and guiding link 56 which is upwardly and forwardly inclined and is generally parallel to the front and rear

seat guide links

36, 42. The back-rest connecting and guiding link 56 has a pivotal connection 53 at its lower end to the forward end of the second carrier member 50 and has a pivotal connection 60 at its upper end 'to the forwardly extending elongated back-rest bracket 23.

Provision is made for coupling the second carrier member 50 to the first carrier member 30 such that during the second movement phase the first carrier member 38 serves as a driver lever while the second carrier member 50 serves as a driven lever. The coupling means includes a coordinating link 62 which has a first coordinating pivot 64 to the first carrier member 30 at a point spaced from the carrier pivot 32 and a second coordinating pivot 66 to the second carrier member 50 at a point spaced from the second carrier pivot 52. The first carrier member 30 intermediate the first coordinating pivot 64 and the first carrier pivot 32 provides the driver lever, while the second carrier member 5% intermediate the second coordinating pivot 66 and the second carrier pivot 52 provides the driven lever. The effective length of the driver lever is longer than the driven lever such that the angular displacement of the driven lever is greater than the corresponding angular displacement of the driver lever during their concurrent movement. Accordingly, for each increment of turning movement of the driver lever, there is a corresponding greater turning movement or angular displacement of the driven lever such that there is an increase in the angular relationship between the seat.24 and the back-rest 22 during the second movement phase. The ratio of the effective lever arms provided respectively by the first and

second carrier members

30, 50 is selected to establish the desired increase in the angular relationship between the seat 24 and the back-rest 22. during the second movement phase, as may be appreciated by comparing FIGS. 2. and 3. At the start of the second movement phase and in the intermediate, tilted sitting position of FIG. 2 it is seen that the first and

second carrier members

30, 50 are substantially paralleL w hile at the end of the second movement phase (as seen in FIG. 3), the second canrier member 50 has turned through a greater angular traverse about the second carrier pivot 52 as compared to the first carrier member 30 which turns about the first carrier pivot 32. Since the seat 24 is effectively unitary with the first carrier member 3;) throughout the second movement phase and the back-rest 22 is coupled to the second carrier member 563 there is a corresponding increase in the angular relationship between the seat and back-rest incident to the accelerated turning of the second carrier member 50 in relation to the first carrier member 36. p

In order to facilitate a more thorough understanding of the environment for a head-rest and control arrangement according to the present invention, a typical sequence of operations of the described recliner type of chair follows:

When the chair occupant is seated in the body-supporting

unit

22, 24 and leans against the back-rest 22, the first movement phase is initiated with the sea 24 being guided relative to the stationary first carrier member 30 to the first intermediate, tilted sitting position. During such first movement phase, the second carrier member 50 which is coupled to the first carrier member 30 remains stationary with the back-rest 22 being guided by the back-rest connecting and guiding link 56 turning about its pivotal connection 58 to the second carrier member 50 as a relatively stationary back-rest pivot. The guiding action of the link 56 will be such as to maintain a substantially fixed angular relationship between the seat 24 and the back-rest 22 in that the link 56 is substantially parallel to the front and rear seat guiding

links

36, 42. When the front seat guiding link "36 abuts the stop 48 at the end of the first movement phase and as the chair arrives at the intermediate, tilted sitting position, the unitary relationship is established between the seat 24 and the first carrier member 34) such that the assembly of the seat, the intermediate seat guiding means and the carrier member 39 turn about the first carrier pivot 32 during the second movement phase. Upon further pressure against the back-rest, there will be a concurrent clockwise turning movement of the first and second carrier members 31), 50 through ascending arc about their respective first and

second carrier pivot

32, 52, with the second carrier member having a greater turning movement than the first carrier member due to the coordinating interconnection 62 therebetween. Accordingly, the back-rest is reclined at a greater rate than the seat is inclined to open up the angle between the seat and back-rest during the second movement phase and as the chair moves through the infinite number of reclining positions to the fully reclined position illustrated in FIG. 3.

Disposed within the upper end of the back-rest 22 is a head-rest 70 which is mounted on the back-rest 22 for movement from a stored position illustrated in FIG. 1 to an extended head-supporting position, shown in FIGS. 2 and 3. The mounting arrangement for the head-rest 70, which is generally designated by the reference numeral 72, includes a first mounting link 74 which is pivotally mounted at a first pivotal mount '76 on the back-rest 22 and is pivotally connected at a first pivotal connection 78 to the head-rest 79. The mounting arrangement 72 further includes second and third mounting links 811, 82 having an intermediate pivotal connection 84. The second mounting link 80 of the mounting link pair 81 82 has a second pivotal mount 86 on the back-rest 22 at a point spaced below the first pivotal mount 76, while the third mounting link 82 has a second pivotal connection movement phase and which moves substantially in an arc about the pivotal mount 32 during the second movement phase. As will appear hereinafter, the relative I movement of the displaceable pivot 26 away from the 38 to the head-rest 70 at a point spaced below the first pivotal connection '78. By appropriate arrangement and dimensioning of the several mounting

links

74, 80 and 82, it is possible to establish a path of movement for the headrest 70 relative to the back-rest 22 such that the head-rest may be brought to a clearance position relative to the back-rest and then to the desired attitude relative to the back-rest for the head-supporting function.

Actuating means are operatively connected to the mounting arrangement or linkage 72, to the body-sup porting means 22, 24 and to the support 12 for moving the head-rest 70 from the stored position illustrated in FIG. l to the extended head-supporting position illustrated in FIGS. 2 and 3. The actuating means or mechanisms includes a displaceable double-arm lever 90, illustrated herein as a plate which is pivotally mounted on the body-supporting

means

22, 24 at a displaceable pivot. In this illustrative embodiment, the displaceable doublearm lever 90 is pivotally mounted coaxially of the backrest pivot 26, with the back-rest pivot 26 serving as the displaceable pivot which moves relative to the support 12 and away from the pivotal mount 32 during the first pivotal mount 32 during the first movement phase causes a movement of the head-rest 70 to the extended headsupporting position; and the arcuate movement of the displaceable pivot in a radius substantially about the pivotal mount 32 during the second movement phase maintains the head-rest 70 substantially in the extended head-supporting position.

The actuating means or mechanisms further includes a pivotally mounted double-arm lever 92 which is mounted intermediate its ends at a fixed pivot 94 provided by appropriate mounting bracket 96 such that the doublearm lever 92 may turn about the fixed pivot 94. The displaceable double-arm lever has an upwardly directed relatively short arm which is coupled by a connecting link 98 to a relatively short arm of the double-arm lever 92. Specifically, the connecting link 98 has a pivotal connection 160 at its lower end to the displaceable doublearm lever 99 at a point spaced from the displaceable pivot 26 thereof and has a pivotal connection 102 at its upper end to the relatively short arm of the double-arm lever at a point spaced from the fixed pivot 94 thereof. The longer arm of the displaceable lever 90 has a pivotal connection 104 to the upper end of an actuating link 106 which has an actuating pivot on the support 12 which is coaxial with the pivotal mount 32 for the first carrier member 30. The longer arm of the double-arm lever 92 is connected to the mounting arrangement 72 by a connecting link 108 which has a pivotal connection 110 at its lower end to the longer arm of the double-arm lever 92 and has a pin and slot connection to the second mounting link 81) provided by a pin 112 fixed to the connecting link 1% and confined within an arcuate slot 114 formed in the second mounting link 81). The link 108 has a pivotal connection 116 at its upper end to the mounting link 74.

In order to facilitate a more thorough understanding of the operation of the improved head-rest and mounting and control arrangement illustrated herein, a typical sequence of operations of the head-rest will now be de: scribed;

When the chair occupant is seated in the body-supporting

means

22, 24 and urges his or her weight rearwardly, the chair moves through the first movement phase, from the sitting position illustrated in FIG. 1 to the intermediate tilted sitting position illustrated in FIG. 2 during which the displaceable pivot 26 and the head-rest actuating mechanisms or means moves away from the pivotal mount 32 and the carrier member 3% it being recalled that the carrier member 30 remains stationary during the first movement phase. Incident to the movement of the displaceable pivot 26 and due to the constraining effect of the actuating link 106, there is a concurrent turning movement of the double-arm lever 90 in the clockwise direction about the displaceable pivot 26 which is moving rearwardly and downwardly. The movement of the displaceable double-arm lever 90 turns both the long arm intermediate the

pivots

26, 104 and the short arm intermediate the pivots 26, in the clockwise direction which exercises a downwardly directed pull on the connecting or coordinating link 98. This downwardly directed pull turns the relatively short arm intermediate the fixed pivot 94 and the pivotal connection 102 of the double-arm lever 92 in a clockwise direction and concurrently turns the long arm intermediate the fixed pivot 94 and the pivotal connection upwardly in a clockwise direction. The ratio of the short and long arms of the double-arm lever 92 is such as to magnify the turning movement imparted thereto, which magnified movement is imparted by the connecting link 108 to the mounting arrangement or linkage 72 to turn the mounting

links

74, 80, 82 upwardly and forwardly about their respective pivotal mounts 76, '86 on the back-rest 22. Such upward movement of the mounting links, turning in the counterclockwise direction, brings the head-rest ill to the extending head-supporting position at the end of the first movement phase, as shown in FIG. 2. In such extended head-supporting position, the actuating link 1% and the long arm intermediate the displaceable pivot 2s and the pivotal connection of the double-arm lever 9b are substantially in alignment with each other such that these links together may be considered to be a single link intermediate the pivotal mount 32 for the carrier member 36 and the displaceable pivot 2i). Accordingly, during the second movement phase, when the seat 24 is effectively a unitary assembly with the carrier member 3% turning about the carrier pivotal mount 32, the displaceable pivot 26 turns in an are about the pivotal mount 32, as the back-rest is reclined. There is substantially no tendency for the dispiaeeable double-arm lever 9t) to turn about the pivot 26 through the second movement phase, as may be appreciated by progressively inspecting the position of the lever t) in the limit positions of FIGS. 2 and 3. Accordingly, substantially no turning movement is imparted to the lever 92 and the head-rest 70 remains in the desired head-supporting position throughout the second movement phase. Although it is preferred to coaxially mount the actuating link 106 on the pivotal mount 32 for the carrier member 3%, it will be appreciated if the pivotal mount for the actuating link 1% were displaced forwardly of the carrier pivotal mount 32 on the carrier member 30, there would be a tendency for the head-rest 76 to move somewhat forwardly during the second movement phase from the illustrated position of FIG. 2. Conversely, if the pivotal mount for the actuating link 1% were displaced rearwardly on the carrier member 31') in relation to the pivotal mount 32, there would be a tendency for the head-rest I'll to move rearwardly from the illustrated position of FIG. 2 in the second movement phase. As required, the actuating arrangement for the head-rest may be arranged to automatically produce minor adjustments of the head-rest relative to the back-rest during the second movement phase.

Although the invention has been illustrated in its specific application to a recliner type of multiple movement chair, it will be appreciated that invention finds application to a tester type of multiple movement chair including a unitary seat and back-rest wherein during the first movement phase the body-supporting unit moves relative to a prescribed pivot to bring about an actuation of the head-rest and during the second movement phase there is a turning movement about such pivot, which maintains the head-rest in a relatively fixed position in relation to the back-rest.

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.
