FIG. 1, the roller 36 is located at the forward end of the
slot 34 of each rear guide member 25, and the roller 42
is located at the forward end of slot 46 of the front guide
members 15, 15a. The engagement of these rollers 36
and 42 with the ends of their respective slots supports
and maintains the seat 28 in the level sitting position.
As shown in FIGS. 2 and 3, the roller unit 60 is seated
in the bottom extension 84 of the slot 48 and is locked
and having a leg-supporting surface 52. At its corner or
apex remote from surface 52, the leg~rest 50 is mounted
by pivot 54 on the forward end of the seat 28. In the
upright- sitting position of the chair shown in FIG. 1,
the leg-rest 59 is disposed in an underslung, retracted
position with its leg-supporting surface 52 inverted and
in this position by spring latch plate 74. The leg-rest 56
is in its retracted, underslung position with the actuat
ing link 58 extending rearwardly therefrom to the roller
parallel to the lower surface of seat 28 and to the floor
surface. During the ?rst motion phase, the leg-rest 56
must be turned about its pivotal mount 54 through 'an
unit 60.
When a person in the chair wishes to assume a more
‘angle of almost 180° to its extended, leg-supporting po
sition, shown in FIG. 4, in which the leg-supporting sur
face 52 faces upwardly and is aligned with the upper
surface of the seat.
The leg-rest movement is achieved by an ‘actuating link
58 which is pivotally connected at one end by pivot 56
to the leg-rest 50 at a point closely spaced from the
pivotal mount 54 of said leg-rest. The rear end of the

36 and 42 then roll to the rear‘ends of their respective
slots 34 and 46, as previously described, to guide the
body-supporting unit 24 through the ?rst motion phase
actuating link 58 is mounted on a carrier element in
the nature of a roller unit 60 movably mounted in the
to the intermediate position of FIG. 4. In this positon,
the body-supporting unit is slightly tilted and the oc

manner to be presently explained.

pair of rollers 64 and 66 journalled upon respective pins
70 and 68 a?ixed to the ends of said body plate 62. A
slot or recess 72 is formed in the central portion of
body plate 62 between the rollers 64 and 66. The roll
ers 64 and 66 are rotatably contained within slot 48.
Roller unit 60 is normally located at the bottom of

viewing television, reading, holding conversation, or the
During the ?rst motion phase, the seat 28 in moving
rearwardly, carries the leg-rest 50 rearwardly with it
through the pivotal connection 54. The actuating link
'58 is, however, restrained from rearward movement be
cause it is mounted upon roller unit 60 which is locked
to the plate 44 by latch plate 74 and therefore constitutes

an immovable part of the support frame 10. The actuat
ing link 58 thus exerts a pushing force or thrust upon
the leg-rest 50 at pivot 5e and causes the rearwardly
moving leg-rest to turn about its pivotal mount 54 on the
roller 42 leaves the recess 72 in roller unit 60, enters slot
46, and moves forwardly and downwardly therein.
As the roller 42 leaves the roller unit 60, its pin 41
frees the latch plate 74, permitting the spring 80 to pull
said latch plate forwardly about pivot 70 until its hook
portion 76 engages pin 78. The roller unit 60 is thus
seat until, in the intermediate position of FIG. 4, the
leg-rest 50 has reached its extended position. In this
position, the leg-rest has turned through an angle of al
most 180° and its leg-supporting surface 52 faces up
again locked to plate 44 so that it cannot rise in slot
48. The actuating link 58 pulls rearwardly upon the
forwardly-moving leg-rest 50 causing the latter to turn
wardly and is substantially aligned with the top forward
surface of the seat 28.

bottom of said second slot during the ?rst motion phase
and having a recess sized to receive and retain said slide
member at the intermediate tilted position whereby said
carrier member is moved upwardly in the second slot by
the forward end portion of the seat during the second mo
tion phase, a leg-rest, means mounting the leg-rest on the
forward end of the seat for movement between a retract
ed position and an extended position, and a leg-rest ac
tuating link operatively connected to said leg-rest
pivotally mounted on the carrier element.
5. A multiple position reclining chair comprising a
port frame, a ‘body-supporting unit including a seat
back-rest, front and rear guide means mounting
rear guide means from said intermediate tilted position to
a fully tilted position, a roller unit slidably contained
in said second slot and having a recess sized and posi
tioned to receive and retain said roller at the end of the
?rst motion phase, whereby said roller unit is carried
upwardly in the second slot by the forward end portion
of the seat during the second motion phase, a leg-rest,
means mounting the leg-rest on the forward end of the
seat for movement between a retracted position and an
extended position, and a leg-rest actuating link operatively
connected to said leg-rest and pivotally mounted on the
roller unit.
6. A multiple position reclining chair according to
claim 5 in which said second slot has a bottom extension
seating the roller unit during the ?rst motion phase with
said recess in registry with the rear end of said ?rst slot.
7. A multiple position reclining chair according to claim
5 in which said roller unit comprises a plate and a pair
of rollers respectively mounted at the end of said plate,
said recess being formed in said plate between said pair of
rollers.
8. A multiple position reclining chair according to
claim 7 in which said plate and said pair of rollers are
disposed in spaced longitudinal planes within said second
slot, the roller mounted on the seat being disposed in
the same plane as said plate.
9. A multiple position reclining chair comprising a
support frame, a body-supporting unit comprising a seat
and back-rest, front and rear guide means mounting the
seat on the support frame for movement through a ?rst
motion phase from an upright sitting position to an inter—
mediate tilted position and then through a second motion
, phase to a fully-tilted position, said front guide means
including a roller carried by the forward portion of the
seat, a ?rst slot receiving the roller during the ?rst motion
phase for guiding the same rearwardly, and a second slot
communicating With the rear end of the ?rst slot for
receiving the roller at the intermediate tilted position and
guide said roller upwardly through the second motion
phase as the seat turns about the rear guide means, a
leg-rest, means mounting the leg-rest on the forward end
portion of the seat for movement between a retracted
position beneath the seat to an extended, leg-supporting
position forwardly of the seat, a leg-rest actuating link
operatively connected at one end to said leg-rest, a roller
unit movably mounted in the second slot and having a
recess therein sized to receive said roller, the roller unit
resting in a stationary position at the bottom of the
second slot during the ?rst motion phase with its recess
in communication with the rear end of the ?rst slot and
positioned to receive the roller at the intermediate tilted
position whereby the roller rises with the forward portion
of the seat during the second motion phase and carries
the roller unit upwardly in the second slot, the other
end of the leg-rest actuating link being pivotally mounted
on the roller unit, the stationary roller unit providing a
?xed pivotal mount for the actuating link during the ?rst
motion phase whereby the actuating link moves the leg
and
rest to its extended position as the leg-rest is moved
sup
rearwardly with the seat, the actuating link being lifted
by the roller unit during the second motion phase to
maintain the leg-rest in its extended position without
and
said. 75 further movement relative to the seat.

10. A multiple position reclining chair according to
claim 9 which also includes latch means for retaining the
roller unit at the bottom of said second slot during the
?rst motion phase.
11. A multiple position reclining chair according to
claim 10 in which said latch means includes a latch‘ plate
having a hook portion, a pin rigid with said support
frame, spring means urging said latch plate to a position
in which its hook portion engages and retains said pin
and in which a portion thereof overlies the recess in 10
said roller unit, the roller carried by said seat having
a portion positioned to engage latch plate in the inter
mediate tilted position and move the latch plate to a
position in Which said hook portion releases said pin.
