the pin and notch rigidly prevent any backward
displacement of pivot G.
It is to be noted that the weight of the user
tends to hold the seat in place, owing to the fact
that the pivot B is located slightly behind the piv
ot A, so that there is no risk of the seat being acci
dentally moved forward and thus causing an
unvoluntary lifting of the back through the me-,

It is to be understood that. without departing
from the scope of the invention, the forms and
details of construction of the various parts of
the arm-chair can be modified, that the connec
tion and guide means described can be replaced
by any other equivalent means, for instance the
pivots G of the back can be guided according to
the path indicated by the broken line IJK and
which is imparted to them by slides of similar
shape secured to the framework, the links 6 being 10
