is positioned to engage the rear roller 18 when the body
supporting unit 12 is slid rearwardly upon the rollers 18
and 20, and act as a pivotal bearing surface for the roller
18 as will be presently described. To avoid contact of
the stop member 26 with the front roller 20 when the body
supporting unit is in its upright sitting position of FIG. 1,
the stop member may be offset laterally from the front
roller 20 and in alignment with the rear roller 18, or the
rear roller 18 may be made wider than the front roller 20
in order to provide a lateral area positioned to engage said
stop member.
In the upright sitting position shown in FIG. 1, the
body-supporting unit 12 rests upon both rollers 18 and 20,
the rear roller 18 being in engagement with the cam sur
face 14a and the front roller 20 being in engagement with
the cam surface 14b.
When the body~supporting unit 12 is moved rearwardly
wardly in a clockwise direction about its pivot 40.
When the body-supporting unit ‘12 is slid rearwardly to
its intermediate tilted position of FIG. 2, the leg-rest pivot
36 is moved rearwardly toward the ?xed pivot 40 of con
trol link 38. The control link 38 thus pushes ‘forwardly
upon the leg-rest 32 at the pivot point 42, causing the leg
rest to pivot upwardly about its pivot 36. When the body
supporting unit reaches its intermediate tilted position, the
leg-rest 32 has pivoted to an extended position forwardly
of and substantially at the level of the front end of the
seat and is held in this position by the control link 38.
This holding function of the control link 38 is determined
by the difference in the two arcs of travel which the con
trol link and the leg-rest would have to travel at point
42 in order to pivot downwardly from the extended posi
tion of FIG. 2. It will be appreciated that in order for
the control link 38 to pivot downwardly, the portion of
to the intermediate tilted position of FIG. 2,, the cam sur
the control link at point 42 must travel through an arc

pivot 42. In order for the leg-rest 32 to pivot down
wardly, the portion of the leg-rest at pivot 42 must travel
traversing the roller 18 causes the rear portion of the
body-supporting unit to be slightly lowered. At the same
time, the downwardly-inclined cam surface 14b, in travers

seat to be slightly raised, with the result that in the inter 60

support, the seat front portion resting on said front roller
and the seat rear portion resting on said rear roller for
rearward sliding movement of the seat along said rollers,
a stop member on said seat engaging said rear roller and
limiting further rearward sliding movement of said seat
on said rollers, the inclined portions of the seat cooperat
ing with said rollers to position said body-supporting unit
roller element and moving rearwardly therealong during
the first motion phase, a stop member carried by said seat
and positioned to engage and grasp said roller element
when the seat has reached its intermediate tilted position
to block further rearward movement of the seat along
said ?rst path of movement whereby further movement of
the seat is limited to pivoting movement about the rotary
axis of said roller element on the support frame along a
second path of movement, the front guide member having
a lost motion engagement with the seat permitting the
forward end of the seat to rise relative to the support
frame during the second motion phase.
