_ t The object of. the invention is, therefore, to
\providen'fmeans whereby the rear seat of a vehicle
will travel forward with the occupants thereof
the vehicle is suddenly restrained.
_ {another object is to increase the comfort of
‘rear seat passengers of motor vehicles by provid
ing a seat that is not rigid, and that is adapted
to slide to compensate for movements of the ve=
. A further object is to provide a movable rear
seat having resilient means for returning the
seat to its normal position.
And a still further object is to provide means
45 for slidably mounting the rear seat of motor
vehicles and the like which is of a simple and
economical construction.
With these ends in view the invention embodies
a track having rollers thereon upon which the
50 rear seat of motor vehicles may be mounted, and
springs connecting said seat to the frame of the
vehicle providing resilient ‘restraining means and
also ‘means ‘for ‘returning the seat to the normal

Other features and advantages of the inven
befused?to permitglsliding thereof‘. The seat is
shown gnounted upon rollers, however, it will be
understood; that, therollers may be omitted and
thelseat maynbe slidable: in the mounting.
fjtllngthe design shown in Figureulathe "seat is 30
provided with a base 4 which is mounted upon
rollers 5 and 6, and these are held in a track]
so that the seat may roll forward orbacktvard?
and at the rear of the seat Pisa projections
which is attached toa spring 8: the ‘opposite end
of which is attached to the frame at thempoint
iii, and it will be noted that as, the ‘seat moves
forward, tension will be placed upon the spring
or springs and as soon as the pressure is released
the spring will return the seat to the normal
The tension spring is also shown in Figure 2,
in which it is indicated by the numeral H, and
in Figure 3, which shows an alternate design, '
the springs 52 are located directly under the seat, 45
and these bear against a ?xed member IS with
the other end engaging a projection I 4 at the.
rear of the seat mounting l5. Inthis design
the seat I6 is mounted upon rollers H and I8 and‘
the vback I9 is hinged to a stationary part 20 of 5Q,
the vehicle through a hinge 2|. This, mounh‘
ing is somewhat similar to the mounting shown in
Figure 1, in which the back}, is ‘mounted bya
hinge 22 at the upperen'd,
in either case the '
back is adapted t6 move forward “with the seat, 55
and the lower edge thereof may be attached to
the seat by a projection 23 shown in Figure 3
or by any means.
In the design shown in Figures 4 and 5 the seat
is provided with rails 24 having flanges 25 at their
lower ends, and these are held between rollers 26
and 2'! at the front and 28 and 29 at the rear, and
these rollers are mounted in sliders 30 which are
also provided with projections 3| that are held be
10 tween rollers 32 and 33 at the front and rollers
34 and 35 at the rear. It will be noted that as
the seat moves outward the ?anges 25 roll out
ward between the rollers and at the same time the
sliders 30 roll outward on the rollers upon which
15 they are mounted.‘ The ?anges 25 may be pro
vided with a stop 36 to limit the outward move
ment of the seat in relation to the sliders 30 and
the sliders may be provided with a projection 31
to limit their outward movement in the frame of
20 the vehicle, which is indicated by the numeral 38.
In this design the seat is provided with springs
39 which are attached to projections 40 at the
rear ends of the rails 24.
~ The seat may also be mounted on an incline as
25 shown in Figure 2 so that after it moves forward
it will have a tendency to roll backward and it will
be noted that by mounting the seat in this man
ner it will be possible to reduce the size of the
comes to a sudden stop the seat will move out
ward and the head backward, whereas with the
seat held stationary the head will be thrown for
ward. It will be understood that although this
device is shown and described as adapted for
motor vehicles it may be used for any other pur
Mounting the seat in this manner produces
the same effect to the seat occupant as would the
gradual application of the brakes as, as the seat 10
moves forward due to any sudden stop, the oc
cupant of the seat will be carried'forward with it,
which action will cause the occupant’s head to be
drawn back instead of being projected forward.
It is this .forward projection of the occupant’s 15
head that is of the gravest danger to him every
time the car is brought to a sudden stop.
It is a common fact that even at moderate
speeds, the sudden application of the modern
type braking power endangers the safety of the
occupants of the rear seat every time this brak
ing power is brought into action.
Therefore, it is evident that the danger and
uncomfort which is always present at every
sudden application. of the brakes in the present
seating construction, is entirely eliminated by the
safety seat as described above.
Having thus fully described the invention, what
I claim as new and desire to secure by Letters
In Figure 6 the seat 4| is provided with a curved
base 42 and this is mounted on rollers 43 in a
curved track 44. In this design the back of the
seat is hinged at the point 45 and the lower end 46
thereof extends through an opening 4'! in the base
Patent, is:
35 42 so that as the seat rolls forward it will draw the
back 48 with it. In this design the base 42 is resil
iently held in the normal position by springs 49.
It will be understood that other changes may
be made in the construction without departing
40 from the spirit of the invention. One of which
changes may be in the use of other means for
slidably mounting the seat, another may be in the,
use of other means for restraining the outward
movement of the seat, and still another may be in
the use of other means for connecting the back
to the seat or for moving the back outward.
The construction will readily be understood
from the foregoing description. In use the device
may be mounted in a motor vehicle or other object
50 as shown and described, or by any other means
and, as hereinbefore stated, when the vehicle
In combination with an automobile body hav

seat thereof, in which the seat is provided with
a back, and the upper edge of the back is hingedly
attached to the rear of the automobile body, said
mounting comprising relatively horizontal tracks
at the opposite sides of the seat and permanently
mounted in the said automobile body, rollers
mounted in bearings, with the bearings ?xedly
attached to the underside of the seat and posi 40
tioned to travel forward and backward in said
tracks, and springs ?xedly attached to the under
side of the seat, and also to the body of the auto

ment of said seat, and forming the only holding
means holding said seat in the normal position;
said device further characterized in that the axes
of said springs are parallel to and in alignment
with the line of force.
