Improved Moveable and Adjustable Seat.
WB, ALBERT RAMMINGER and KONRAD STETTER of 41 Hookhauser Strasse,
Taubenbischofsheim, Baden in the Empire of Germany, Cabinetmakers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement
This invention has for its object to provide a comfortable seat in narrow space
whilst permitting of unconstrained rising and upright standing.
Figures I to IV represent the improved seats as adapted for school benches.
Figure I shows the seat during use by a scholar.
Figure II shows the same after the scholar has risen.
Fi
igure III the seat in rest.
Figure IV the same completely thrown back.
Figure V shows the application of the same for theatres, colleges church
benches &c.
The object of the invention is obtained by application of a knuckle jointed
doubled seat whose parts a and b are connected through a knuckle joint c whilst
both parts together are connected to the rear of the bench by means of a hinge d
which also enables the seat to be thrown back altogether-A carved flat spring e
is adjusted under the bipartite sitting plate in such a manner that the seat will be
alightly raised in the centre if the place is not occupied (see Figure III)-This
adjustment gives more facility to a person when suddenly rising as it greatly
supports the back motion during the movement of leaving the seat By application
of this seat in theatres colleges or churches &c. a quicker and easier rising will be
obtained in order to let other persons pass by-On the other hand the standing of
the person who has risen from the seat is much more comfortable while disturbing
noise during rising as well as sitting down is avoided.
On the school bench provided with this seat the table edge projects about
20 m. m. beyond the edge of the seat whilst the scholar is sitting (see Fig. 1).
In case of the sudden rising of the scholar the same amount of space will be
gained on the seat as the latter can be pushed back without special handling by
means of a slight pressure with the legs and fold itself up into the position shown
in Figure II.
In the case of any person sitting down or leaving the seat the same will by itself
fall back into the position shown at Figure I or III. If the sohalar has to stand
a considerable time the whole seat may be thrown back into the position shown at
Figure IV. Every scholar receives a special seat. The seat frames may, however,
be arranged with two, three, four and more seats and the rising and sitting down
takes place noiselessly and without any disturbance On theatre seats &o. the
arrangement of the seats will have to be made to answer the purpose in view and
the table will be done away with.
As the school benches made after this system may be constructed of wood
they will be commendable in practice on account of cheapness and easy con-
veyance.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
A hinged or folding seat for school benches and theatre seats consisting of two

when the seated person rises so that it remains in a roof-like position in order to
up less space.
