reference numeral 38, is pivotally suspended from the
carrier member 28, operatively connected to the leg-rest

positions. The leg-rest control linkage 33 includes a
?rst pair of links 40, 42 having a pivotal connection 44
at their adjacent ends, a second pair of links 46, 48 hav
ing a pivotal connection 50 at their adjacent ends, and
a third pair of links 52, 54 having a pivotal connection
55 at their adjacent ends. The link 40 of the ?rst link
pair 40, 42 is pivotally mounted on the forward end of
the carrier member 28 at a pivotal connection or mount
56, while the second link 42 crosses over the link 46 and

by progressively inspecting FIGS. 1 and 2 that there will
be lost motion travel and no coupling of movement from
the body-supporting unit 16 to the carrier member 28
until the lower end of the slot 80 abuts the pin 82; and
thereafter during the second movement phase, the pin
82 serves as an effective pivotal connection between the
actuating link 76 and the carrier member 28.
In order to facilitate a more thorough understanding
of the present invention, a typical sequence of operations
will now be described:
When the chair occupant is seated in the body-support
ing unit '16 and urges his weight rearwardly, the body
supporting unit turns around the main pivot 24 and the
leg-rest mounting or control linkage 38 is actuated from
the coupling link 68, it being recalled that the carrier
member 28 remains in a stationary position relative to
the support. No coupling is provided via the actuating
link 76 to the carrier member 28 from the body-support
ing unit 16 in that-there is lost motion between the ac
tuating link 76 and the carrier member 28 during the ?rst
movement phase. The end of the ?rst movement phase
