64 through a lost motion travel such that the leg-rest
52 is maintained in the requisite elevated leg-supporting
position in relation to the seat 22, it being appreciated
that the over elevation of the leg-rest beyond the illus
trated positions would bring the leg-rest into a rela
tionship relative to the seat such that it would not com
fortably support the legs of the chair occupant.
In order to facilitate a more thorough understanding
of the present invention, reference will now be made
to a typical sequence of operations:
When the chair occupant is seated in the chair and
leans against the back-rest 22 there will be a tendency
for the back-rest to turn about the pivotal connection

from the reclining position to the intermediate tilted posi
tion or to the upright position, the occupant merely leans
forward and causes the chair to move through the re
verse sequence of operations.
A latitude of modi?cation, change and substitution is
intended in the foregoing disclosure and in some instances
some features of the invention will be employed without
a corresponding use of other features. Accordingly it is
appropriate that the appended claims be construed broadly
and in a manner consistent with the spirit and scope of
