"Improvements in Car Seats."
I, JOHN LIDDLE, of 154, St. Vincent Street, in the County of the City of
Glasgow, North Britain, Patent Agent, do hereby declare the nature of this
Invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My present invention relates to improvements on that class of seats in which
the back is reversed with relation to the bottom, or reversed and turned, and the
bottom is shifted back and forth by the movement of the back in changing the
facing direction of the car-seat.
The primary object of the invention is to construct a seat in such a manner that
the back may be readily and easily shifted with as little friction as possible and with
perfect accuracy of movement.
Another object of the Invention is to provide movable pivots for the parts
supporting the back whereby the latter may be quickly shifted without the
shifting devices binding.
A further object is to adapt my shifting devices to seats provided with backs
which do or do not turn completely over.
And further object is to provide means for simultaneously shifting the seat
and back, or shifting the seat and shifting and turning the back.
With these and other ends in view, the invention comprises, at each end of
the seat, a frame and arms or links pivotally supporting the back and provided
with movable pivots in said frames, said arms or links being adapted to simul-
taneously adjust the seat as the back is shifted.
My Invention consists also of the details of construction and arrangement of
parts which will be fully pointed out and claimed hereinafter.
In the accompanying Drawings
Figure 1 is a view, partly in section, showing my Invention embodied in a
reversible car-seat, the opposite position of the back and other movable parts,
being shown in dotted lines.
Figure 2, shows my Invention applied to a car-seat in which the back is
turned as well as reversed.
Referring to the drawings, in which like letters of reference denote corra-
sponding parts in all the figures, the seat is of the usual construction, in which
the cushion A is supported upon rockers or runners B loosely arranged on-the
sills C. The ends of the rockers or runners project over the sills, and are prefer-
ably bevelled on their lower sides to facilitate their movement on the inwardly
inclined or bevelled sills. The sills are supported on a frame D in a suitable
manner.
On the side of the car, or at the end of the seat, I provide a frame E, which
has a slot or slots F therein, and a rack-bar G on the upper side thereof. One

page_text: of these frames is arranged in a suitable manner at each end of the seat, and I
will hereinafter describe the construction at one end only of the seat.
The arms or links H which support the back I, are movably pivoted at their
lower ends in said frame. Two of these arms are employed at each end of the
seat, and the lower ends of said arms are rigidly secured to the horizontally
movable shafts J, which project into and have bearings in the slot F in saud
frame. Adjacent to the lower ends of said arms, segments K are rigidly secured
on the shafts J and provided with teeth adapted to engage the rack-bar G. It
is obvious that instead of these two segments may employ pinions or devices
of a similar nature which are designed to accomplish the same results. A down-
ward projection is arranged at or about the middle of each sil 13 and, in
Figure 1 of the drawings, I have illustrated one form of this projection which
comprises a plate L with two downward extensions M, which are arranged-
between and in contact with the shafts J. Instead of this plate L, many other
forms may be employed for this projection, and I have found a single projection,
of sufficient size to contact with each of the shafts J, to be also a desirable
form.
It will thus be observed that the seat is simultaneously shifted with the move-
ment of the back. As the movable pivots on the lower ends of the arms H, con-
stituted by the shafts J, move in the other direction from that in which they
rest, the downward projection on the sill is also moved by said shafts. In this
way the seat is shifted to the desirable extent and at the same time as the back.
In Figure 2 of the drawing, I have shown my Invention applied to a seat, in
which the back thereof is adapted to be turned as well as shifted. In this
Application of my Invention, the arms H are pivoted directly to the back, at or
about the middle thereof, instead of to plates N on the back. The other parts
are constructed in substantially the same manner, the only changes necessary
being those within the knowledge and skill of a person familiar with the art.
I am aware that changes in the form and proportion of parts and details in
the construction of my Invention may be made without departing from the
spirit or sacrificing the advantages thereof, and I therefore reserve the right to
make all such changes which fall within the scope and spirit of the Invention.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what I
claim is:-
J
1. In a reversible car-seat, the combination with a back, of the arms pivoted
to and supporting said back, frames at the ends of the seat and movable pivots
on the lower ends of said arms adapted to be shifted laterally as the back is
reversed, substantially as described.
2. In a reversible car-seat, the combination with a back, of the arms pivotally
supporting said back, frames at the ends of the seat and the horizontally movable
shafts mounted on the lower ends of said arms and constituting movable pivots
therefor, substantially as described.
3. In a reversible car-seat, the combination with a back, of supporting armis
pivotally secured to said back, movable pivots on the lower ends of said arms
adapted to be shifted as the back is reversed, a seat arranged to be shifted simul-
taneously with the back by the lateral movement of said pivots, and frames at
the ends of the seat, substantially as described.
4. In a reversible car-seat, the combination with a back, of supporting arms
pivotally secured to said back, movable pivots on the lower ends of said arms
adapted to be shifted as the back is reversed, a seat adapted to he shifted simul-
taneously with the back, frames at the ends of the seat and downward projections
on said seat arranged between the said movable pivots and controlled thereby,
substantially as and for the purpose described.
5. In a reversible car-seat, the combination with a back, of supporting arms
pivotally secured to said back; movable pivots for the lower ends of said arms

page_text: adapted to be shifted as the back is reversed, a seat, frames at the ends of the
seat, the rockers supporting said seat, and downward projections on said rockers
arranged between and in contact with the movable pivots, whereby said seat is
shifted simultaneously with the reversal of the back, substantially as described.
6. In a reversible car-seat, the combination with a back, of frames secured
at each end of the seat, the movable pivots operating in said frames, and the
parallel arms supporting said back and secured to said movable pivots substan-
tially as described.
7. In a reversible car-seat, the combination with a back, of frames secured
at each end of the seat, shafts operating in slots in said frames, and the parallel
arms pivotally supporting the back and rigidly secured at their lower ends to

8, In a reversible car-seat, the combination with a back, of frames secured at
each end of the seat, shafts operating in slots in said frames, the arms supporting
the back and rigidly secured to said shafts, a rack-bar on each frame, and the
toothed segments rigid with the shafts and engaging said rack-bars, subston-
tially as described.
9. In a reversible car-seat, the combination with a back, of frames secured at
each end of the seat, shafts operating in slots in said frames, the arms supporting
the back and rigidly secured to said shafts, a rack bar on each frame, the toothed
segments rigid with the shaft and engaging said rack-bars, a seat, and down-
ward projections on said seat arranged between and in contact with said shafts,
substantially as described.
10, In a reversible car-seat, the combination with a back, of frames secured at
each end of the seat and provided with slots therein, shafts extending through
and having bearings in said slots, a rack-bar on each frame, the supporting
