Schliephacke, Berlin-Schmargendorf, Germany, assignor to Anton Lorenz, Boynton Beach, Fla. Filed July 13, 1961?, Ser. No. 42,549 9 Claims. (Cl. 297-321) The present invention relates generally to reclining chairs of the multiple movement type, and in particular to an improved reclining chair incorporating a body-supporting unit including a movable seat and movable backrest which are coordinated to each other to establish multiple chair positions.

The recently developed multiple movement chair of the recliner type comprises a support and a body-supporting unit including a movable seat and a movable backrest which are mounted on the support for first and second movement phases. During the first movement phase, the seat and back-rest move from the sitting position to an intermediate tilted sitting position during which there is substantially no change in the angular relationship between the seat and back-rest; and during the second movement phase the seat and back-rest move from the intermediate sitting position through various reclining positions to a fully reclining position, with a progressive increased in the angular relationship between the seat and back-rest. Such multiple movement chair of the recliner type usually incorporates a leg-rest which is mounted for movement to a substantially elevated legsupporting 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.

There exists the need for relatively simple and compact mechanisms for achieving the coordinated movement of the seat and back-seat during the first and second movement phases. Further, provision should be made in this type of chair to establish the order or sequence of operations of the mechanisms to assure that the bodysupporting means will be properly guided during the first and second movement phases respectively to establish the multiple positions for the chair. Such sequencing means for the chair should be of a positive and reliable nature and preferably should be automatically operated when the chair occupant is seated and exerts the necessary actuating force on the body-supporting means of the chair. Still further, the sequencing means should be generally compatible with the more generalized requirements of simplicity and construction and facility for mass production manufacture.

Broadly, it is an object of the present invention to provide an improved recliner type of multiple movement chair which realizes one or more of the aforesaid objectives. Specifically, it is within the contemplation of the present invention to provide a recliner type of multiple movement chair which provides for respective first and second movement phases for the chair, with the initial movement of the body-supporting means to an intermediate tilted position with substantially no angular change between the seat and back-rest, and the further movement of the chair through successive reclining positions with an increase in the angular relationship between the seat and back-rest.

It is a further object of the present invention to provide an improved multiple movement chair of the recliner type which incorporates as part of the coordinating mechanisms thereof a sequencing arrangement which establishes the order of operations for the coordinating mechanisms to assure proper chair operation.

In accordance with an illustrative embodiment demonstrating objects and features of the present invention, there is provided a reclining chair comprising a support and body-supporting means including a seat and backrest adapted to be mounted on said support for inclining and reclining movement respectively from a sitting position to an intermediate tilted sitting position to a reclining position in a second movement phase. A front seat guiding link is pivotally connected to the seat and means including a lost motion connection providing a front pivotal mount for the front seat guiding link on said support. A rear seat guiding link is pivotally mounted on the support and pivotally connected to the seat, the front and rear seat guiding links serve dun'ng the first movement phase to guide the seat upwardly and rearwardly relative to the support to a first inclined position. A backrest guiding link is pivotally mounted on the support at a pivotal mount and means pivotally connected to the back-rest. Means are provided for blocking lost motion travel of the front guiding link relative to the support during the first movement phase and enables the lost motion travel during the second movement phase. The front and rear seat guiding links cooperate with the back-rest guiding link during said first movement phase to maintain a substantially fixed angular relationship between the seat and back-rest and the front and rear seat guiding links cooperate with the back-rest guiding link during said second movement phase to increase the angular relationship between the seat and back-rest, with the front seat guiding link having a lost motion travel relative to the support and with the seat turning on the pivotal connection to the rear seat guiding link.

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 presently preferred, but nonetheless illustrative embodiments, according to the present invention, wherein:

FIG. 1 is a side elevational view, with parts broken away, of a reclining chair demonstrating features of the present invention, shown in the upright or sitting position;

FIG. 2 is a side elevational view similar to FIG. 1, but showing the chair in its intermediate tilted sitting position;

FIG. 3 is a side elevational view similar to FIG. 1, but showing the chair in a fully reclined position;

FIG. 4 is a side elevational view of another embodiment of a reclining chair demonstrating further features of the invention, shown in the upright or sitting position;

FIG. 5 is a side elevational view similar to FIG. 4, but showing the chair in the intermediate tilted sitting position; and,

FIG. 6 is a side elevational view similar to FIG. 4, but showing the chair in a fully reclined position.

Referring now specifically to FIGS. 1 to 3 of the drawings, there is shown a reclining chair, generally designated by the reference numeral 10, which includes a chair frame or support 12 having

opposite side walls

14, 16 interconnected by a number of cross braces 18 and supported on depending legs 20. A body-supporting means or unit including a back-rest 22 and the seat 24 are mounted on the support for reclining and inclining movement respectively through a first movement phase from the upright or sitting position illustrated in FIG. 1 to the intermediate tilted 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 position illustrated in FIG. 3. In the interest of simplicity, there is no showing of the leg rest and its mounting and controlled arrangement which is usually found in a chair of this type. However, it will be appreciated that such leg-rest will be incorporated in the chair which leg-rest moves to an elevated leg-supporting position as the bodysupport-ing means moves into the intermediate tilted sitting position illustrated in FIG. 2. Effectively the legrest provides a support for the legs of the chair occupant as the chair is moved from the intermediate tilted sitting position through the various reclining positions to the fully reclined positions illustrated in FIG. 3. The details of such leg-rest and its mounting and control arrangement, as well as its incorporation into the present chair, will be generally understood to those skilled in the art and typical arrangement may be found in the prior art patents of the assignee herein.

Seat guiding means are operatively connected between the support 12 and the seat 24 for imparting a first inclination to the seat during the first movement phase, as may be seen in FIGS. 1 and 2, and for imparting a second inclination to the seat during the second movement phase, as may be seen by comparing FIGS. 2 and 3. The seat guiding means includes a front seat guiding link 26 which is upwardly and forwardly inclined and has a front pivotal connection 28 to the seat 24. Means including a lost motion connection provide a front pivotal mount for the front seat guiding link 26 on the support 12. In this illustrative embodiment, a mounting bracket 30 is fixed to the chair frame or support 12 (i.e. at the cross brace 18) and carries a pin 32 which is confined within an elongated slot 34 formed within the lower end portion of the front seat guiding link 26. The pin 32 remains at the upper end of the slot 34 during the first movement phase and provides the front pivotal mount for the front seat guiding link 26. During the second movement phase, there is a lost motion travel between the pin and

slot interconnection

32, 34, with the link 26 translating upwardly such that the pin 32 is confined at the lower end of the slot in the fully reclined position illustrated in 'FIG. 3. The seat guiding means further includes a rear seat guiding link 38 which is up- Wa-rdy and forwardly inclined and has a rear pivotal connection 40 at its upper end to the seat 24- at a location spaced rearwardly of the front pivotal connection 28. The rear seat guiding link 38 has a rear pivotal mount 42 on the support 12 provided by an appropriate bracket 44. The front and rear seat guiding

links

26, 38, serve during the first movement phase to guide the seat upwardly 4 and rearwardly relative to the support to a first inclined postion and during the second movement phase to guide the seat 24 to a second inclined position, with the front seat guiding link 26 having a lost motion travel relative to the support 12, and with the seat 24 turning on the rear pivotal connection 40.

Turning now to the back-rest mounting and guiding arrangement, the backrest 22 is pivotally mounted on the seat 24 at a back-rest pivot 46 such that the backrest may move substantially as a unit with the seat 24 during the first movement phase and recline relative to the seat 24 during the second movement phase to increase the angular relationship therebetween. Spaced forwardly of the back-rest pivot 46 is a back-rest guiding link 48 which in this illustrative embodiment is forwardly and downwardly inclined. At its upper end the back-rest guiding link 48 has a pivotal mount 50 on the support provided by an appropriate bracket 52, and at its lower end the back-rest guiding link 48 has a pivotal connection 54 to the forwardly projecting extension of the back-rest pivot '46. The back-rest guiding link 48 cooperates with the seat guiding

links

26, 38 during the first movement phase to maintain a substantially fixed angular relationship between the seat 24 and the back-rest, and during the second movement phase to increase the angular relationship between the seat and back-rest.

Provision is made for blocking or precluding lost motion travel of the front guiding link 26 relative to the support 12 during the first movement phase and for enabling such lost motion travel during the second movement phase. The blocking or sequencing means includes a double-arced slot 56 formed on the mounting bracket 30 adjacent the front seat guiding link 26 and guidingly engaging a pin 58 fixed to the lower end of the front seat guiding link 26. The double-arced slot 56 includes a first slot section 56a merging with a second slot section 5612 at a junction 560. The pin 58 is at the end of the first slot section 56a remote from the junction 560 in the sitting position of the chair and translates along the first slot section 56a during the first movement phase, as may be appreciated by comparing FIGS. 1 and 2. The curvature of the first slot section 56a is selected at a radius about the pivotal mount 32 (such radius being measured between the pins 32, 58) to confine the front seat guiding link 26 to turning movement about the front pivotal mount 32 while at the upper end of the lost motion slot 34. The second slot section 56b is substantially aligned with the lost motion slot 34 when the chair is in the intermediate tilted sitting position of FIG. 2, and is of an appropriate curvature to enable the lost motion travel of the pin and

slot interconnection

32, 34 during the second movement phase such that the front seat guiding link 26 may translate upwardly relative to the support, as may be appreciated by comparing FIGS. 2 and 3.

Appropriate stops are provided to establish the several chair positions, as is generally understood. Specifically, the seat guiding means is blocked in the intermediate tilted sitting position by a stop 60 fixed to the chair frame or support 12 behind the rear seat guiding link 38 to block clockwise turning movement thereof about the rear pivotal mount 42 when the chair arrives at the intermediate tilted sitting position of FIG. 2. Thereafter, and as previously indicated, there is a turning movement of the seat about the rear pivotal connection 40 with a corresponding lost motion of the front seat guiding link 26 relative to the support to the fully reclined position of FIG. 3. In this illustrative embodiment, the fully reclined position is established by contact of the lower end of the back-rest 22 with the rear cross brace 18 serving as a stop.

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

As the chair occupant leans against the back-rest 22 and pushes rearwardly, the seat 24 will be guided by the seat guiding means which includes a four-bar seat guiding linkage having as movable links thereof the front seat guiding link 26, the portion of the seat 24 intermediate the front and rear

pivotal connections

28, 40, and the rear seat guiding link 38, and as the stationary link thereof the portion of the support intermediate the front and rear

pivotal mounts

32, 42. During such first movement phase, the guiding action on the back-rest 22 from the back-rest guiding link 48 is such as to maintain a substantially fixed relationship to the seat 24, with the bodysupporting unit moving into the intermediate tilted sitting position illustrated in FIG. 2 wherein further turning movement in the clockwise direction of the rear seat guiding link 38 is precluded by the stop 60. Thereupon, continued pressure by the chair occupant against the backrest 22 will cause the turning movement of the seat 24 about the rear pivotal connection 40 with a concurrent lost motion travel of the front seat guiding link 26 relative to the support. During such second movement phase, the guiding action of the back-rest guiding link 48 on the back-rest 22 is such as to open up the angle between the seat and back-rest, as shown in FIGS. 2 and 3, with the fully reclined position being established when the lower end of the back-rest 22 contacts the rear cross brace 18.

Referring now specifically to FIGS. 4 to 6 of the drawings, there is shown a further embodiment of reclining chairs, generally designated by the reference numeral 118,

which includes a chair frame or support 112 having

opposite side walls

114, 116 interconnected by a number of cross braces 118 and supported on depending legs 120. A body-supporting means or unit including a back-rest 122 and the seat 124 are mounted on the support for reclining and inclining movement respectively through a first movement phase from the upright or sitting position illustrated in FIG. 4 to the intermediate tilted position illustrated in FIG. 5 and for a second movement phase from the intermediate tilted sitting position illustrated in FIG. 5 through a series of reclining positions to the fully reclined position illustrated in FIG. 6. Again, in the interest of simplicity, there is no showing of the legrest and its mounting and controlled arrangement which is usually found in the chair of this type.

Seat guiding means are operatively connected between the support 112 and the seat 124 for imparting a first inclination to the seat during the first movement phase, as may be seen in FIGS. 4 and 5, and for imparting a second inclination to the seat during the second move ment phase, as may be seen by comparing FIGS. 5 and 6. The seat guiding means includes a front seat guiding link 126 which is upwardly and forwardly inclined and has a front pivotal connection 128 to the seat. A mounting bracket 130 is fixed to the chair frame or support 112 (i.e. at the cross brace 118) and carries a pin 132 which is confined within an elongated slot 134 formed within the lower end portion of the front seat guiding link 126. The pin 132 remains at the upper end of the slot 134 during the first movement phase and provides a front pivotal mount for the front seat guiding link 126. During the second movement phase, there is a lost motion travel between the pin and

slot interconnection

132, 134, with the link 126 translating upwardly such that the pin 132 is confined at the lower end of the slot in the fully reclined position illustrated in FIG. 6. The seat guiding means further includes a rear seat guiding link 138 which is upwardly and forwardly inclined and has a rear pivotal connection 148 at its upper end to the seat 124 at a location spaced rearwardly of the front pivotal connection 128. The rear seat guiding link 138 has a rear pivotal mount 142 on the support 112 provided by an appropriate bracket 144. The front and rear

seat guiding links

126, 138 serve during the first movement phase to guide the seat upwardly and rearwardly relative to the support to a first inclined position, and during the second movement phase to guide the seat 124 to a second inclined position, with the front seat guiding link 126 having a lost motion travel relative to the support 112, and with the seat 124 turning on the rear pivotal connection 140-.

Turning now to the back-rest mounting and guide arrangement, the back-rest 122 is pivotally mounted on the seat 124 at a back-rest pivot 146 such that the backrest may move substantially as a unit with the seat 124 during the first movement phase and recline relative to the seat 124 during the second movement phase to increase the angular relationship therebetween. Spaced forwardly of the back-rest pivot 146 is a back-rest guid ing link 148, which in this illustrative embodiment is upwardly and forwardly inclined. At its lower end the back-rest guiding link 148 has a pivotal mount 150 on the support provided by an appropriate bracket 152, and at its upper end the back-rest guiding link 148 has a pivotal connection 154 to the forwardly projecting extension of the back-rest 122 at a location forwardly of the back-rest pivot 146. The back-rest guiding link 148 cooperates with the

seat guiding links

126, 138 during the first movement phase to maintain a substantially fixed angular relationship between the seat 124 and the backrest 122, and during the second movement phase to increase the angular relationship between the seat and backrest.

Provision is made for blocking or precluding lost motion travel of the front guiding link 126 relative to the support 112 during the first movement phase and for enabling such lost motion travel during the second movement phase. The blocking or sequencing means includes a double-arced slot 156 formed on the mounting bracket adjacent the front seat guiding link 126 and guidingly engaging a pin 158 fixed to the lower end of the link 1126. The douhle-arced slot 156 includes a first slot section 156a merging with a second slot section 15612 at a junction 1560. The pin 158 is at the end of the first slot section 15601 remote from the junction 156s in the sitting position of the chair and translates along the first slot section 156a during the first movement phase, as may be appreciated by comparing FIGS. 4 and 5. The curvature of the first slot section 156a is selected at a radius about the pivotal mount 132 to confine the front seat guiding link 1.26 to turning movement about the front pivotal mount 132 while at the upper end of the lost motion slot 134. The second slot section 15612 is substantially aligned with the lost motion slot 134 when the chair is in the intermediate tilted sitting position of FIG. 5 and is of an appropriate curvature to enable the lost motion travel of the pin and

slot interconnection

132, 134 during the second movement phase such that front seat guiding link 126 may translate upwardly relative to the support, as may be appreciated by comparing FIGS. 5 and 6.

Appropriate stops are provided to establish the several chair positions, as is generally understood. Specifically, the seat guiding means is blocked in the intermediate tilted sitting position by a stop 160 fixed to the chair frame or support 112 behind the rear seat guiding link 138 to block clockwise turning movement thereof about the rear pivotal mount 142 when the chair arrives at the intermediate tilted sitting position of FIG. 5. Thereafter, there is a turning movement of the seat about the rear pivotal connection With a corresponding lost motion of the front seat guiding link 126 relative to the support until the chair arrives at the fully reclined position. In this illustrative embodiment, the fully reclined position is established by contact of the lower end of the back-rest 122 with the rear cross brace 118 serving as a stop.
