present invention:
When the chair occupant is seated in the chair in the
upright or sitting position illustrated in FIG. 1 and wishes
being ?xed on a ?xture or bracket 48 secured to the sup
port, and with the second pivotal mount or pivot 46 being
?xed on a ?xture or bracket 50 secured to the support.
Means are provided for mounting the seat control mem
ber 40 for turning movement about the ?rst pivotal mount
44 during the ?rst motion phase of the chair and for dis
placement relative to the, ?rst pivot during the second
motion phase and for further mounting the seat control
member 40 for turning movement about the second
pivotal mount 46 during the second motion phase. In this
illustrative embodiment, the seat control member 453 is
provided with a ?rst integral guide member 52 formed
with a guideway 54 and a second integral guide member
56 formed with a guideway 58. The guideway 54 in
cludes terminal or seating portions 54a, 54b serving as
respective bearings for the second pivotal mount 46 with
the guideway having a curvature on a radius about the
?rst pivotal mount 44. The guideway 58 includes termi
nal or seating portions 53a, 58!) serving as respective
bearings for the pivotal mount 44, with the guideway 53
having a curvature on a radius about the second pivotal
mount 46. Stated somewhat di?erently, the curvature of
the respective guideways 54, 58 is on a radius equal to the
spacing between the respective pivotal mounts 44, 46.
During the ?rst motion phase of the chair movement, the
seat control member 40 turns on the ?rst pivotal mount
44 which is seated within the terminal or seating portion
58a of the guideway 58, with the guide member 52 and
guideway 54 being translated or displaced through a down
ward lost motion travel relative to the second pivot or
mount 46. During the second motion phase, the second
pivotal mount 46 is seated at the terminal or seating por
tion 54b of the guideway 54 which mounts the seat con
trol member 40 for turning movement about the pivotal
mount 46 as a relatively stationary pivot, with the guide
member 56 and guideway 58 being displaced or translated
through an upward lost motion travel relative to the ?rst
pivotal mount 44. The seat control function during the
?rst phase of the reclining movement is determined by the
spacing between the terminal or seating portion 58a of
the guideway 58 and the pivotal connection 42 to the
seat since the ?rst pivotal mount 44 is effectively pivoted

10 clining movement of the back-rest 20 pulls the seat 22
rearwardly which in turn causes the pivotal connection 42
to the seat control member 40 to move through an upward

about the pivotal mount 44. The portion of the seat con
trol member 40 intermediate the pivots 42, 44 imparts a
?rst inclination to the seat appropriate to maintain a sub~
stantially ?xed angular relationship between the back
rest 29 and the seat 22. The rearward displacement of
the seat 22 under the control of the back-rest 20 is fur
ther effective to cause the pivotal connection 36 to the leg
rest hanger arm 32 to move rearwardly relative to the
pivotal connection 62 thus moving the leg-rest into an
elevated leg-supporting position relative to the seat 22.

time as the upper terminal

the pivotal mount 46 thereby effectively blocking further
turning movement of the control member 40 about the
pivotal mount 44. When the pivotal mount 46 is engaged
by the terminal portion 54b of the guideway 54, the end
of the ?rst motion phase of the chair is established, with
the back-rest 20 and seat 22 rocked rearwardly into an
intermediate tilted or semi-reclined position, with the leg
rest elevated as shown in FIG. 2.
Upon further pressure against the back-rest by the chair
occupant the second phase of the chair movement is
initiated, with the seat control member 40 turning about
the pivotal mount 46 journaled at the upper terminal
portion 54b of the guideway 54. During the second
phase of the reclining movement the portion of the seat
control member 40 intermediate the pivots 42, 46 serves
to achieve the seat control function, with the pivotal mount
44 translating along the guideway 58 until such time as

the pivotal mount 44 establishing the end of the second

mount 46, as may be seen by progressively inspecting
FIGS. 2 and 3. When the chair occupant desires to
