20 Claims.
This invention relates to adjustable seats
especially designed and adapted for use in vehicles
such as automobiles, and has particular reference
to an improved seat slide assembly.
Q1
The principal object of our invenution is to
provide a seat slide of stamped sheet metal con
struction throughout for lightness and economy,
while still possessing the requisite strength and
10.
H previously mentioned, and the member l5
being secured in any suitable manner to the legs
l3 as by rivets Hi. The longitudinal members
provide channels I‘! therein in which rotary spac 5
ing means operate to maintain the members in
a normal spaced relationship. In the present case,
the spacing means are rollers l8 having gears
rigidity.
l9 therebetween meshing in longitudinally spaced
The salient feature of our invention is the pro
vision of sheet metal links as tie members or
holes 20 provided therefor in the members l4 and 10
I5, whereby to maintain the rollers at the front
fasteners to hold the parts of the assembly to
gether, the same being arranged to be inserted
through the assembly and then twisted to fasten
the parts permanently in assembled relation. In
the twisting of these ties there is a certain short
ening in length suiiicient to cause the parts to be
and rear of the seat in the same longitudinally
spaced relation in any position of adjustment of
the seat. In that way the seat is assured of the
same easy movement from any position of ad- 15
drawn together tightly to eliminate undesired
play, and in accordance with our invention a part
20 of the assembly has inclined cam surfaces formed
thereon on which the crossheads on the ties are
arranged to ride as the ties are twisted, whereby
to provide for the desired variation in the
amount of slack take-up as required due to such
25 . slight discrepancies in size and ?t of the parts as
will occur in quantity production.
The invention is illustrated in the accompany
ing drawing, in which—
‘
Figs. 1 and 2 are a plan view and side view, re
30 spectively, of a seat slide made in accordance with
our invention;
Figs. 3 and 5 are cross-sections on the corre
spondingly numbered lines of Fig. 2 on a larger
scale;

(01. 155-14)
bers I4 and Hi, the member I4 carrying the bolts
Fig. 4 is a horizontal sectional detail on the
line 4—-4 of Fig. 3;
Fig. 6 is a perspective view of one of the tie
members, and
Figs. '7 and 8 are perspective views showing the
40 ends of the two side channel members of the as
justment. The lever, indicated at 2| as pivoted on
the member M at 22 and having a lug 23 pro
jecting from the free end thereof, is arranged to
be urged normally in a counterclockwise direction
by the wire spring 24 to lock the member M
in adjusted position by engagement of the lug 23
in any one of a plurality of longitudinally spaced
notches (not shown) provided therefor in the
member [5. Incidentally, this spring, being an
chored in the member [4, as indicated in Fig. 1, 25
and being carried on the tie member 28 mounted
in the sheet metal channel members 25 and 26,
serves to lock the channel members 25 and 26 to
the member l4 to move back and forth with the
seat, relative to the other member l5. When the 30
seat is to be adjusted the lever 2i must be moved
against the action of the spring 213 so as to disen
gage the lug 23 from the notch, whereupon the
member I4 is free to slide endwise with respect
to the member l5 in either direction. When the
seat is in the desired position, the lever 2! is re
leased and automatically seeks locking position.
In accordance with our invention, the longi
tudinal members It and I5 are stamped from
sheet metal to provide outwardly projecting lon
sembly showing one of the keyhole slots provided
gitudinal ?anges l4’ and I5’, respectively, and
in one of these members, and the cam formations
the sheet metal channel members 25 and 26 re
ceive these ?anges in the channels thereof so as
in connections with the keyhole slots in the other
member.
45
The same reference numerals are applied to
corresponding parts throughout the views.
The seat slide assembly with which our inven~
tion is concerned is indicated generally by the
reference numeral l0. There are two such slides
50 provided in connection with each seat, attached
to the bottom of the seat by means of bolts II or
in any other suitable manner, and secured to and
supported upon the floor l2 on legs l3, suitably
of hollow sheet metal construction. Each slide
55 comprises upper and lower longitudinal mem~
to hold the longitudinal members l4 and I5
against displacement from assembled relation 45
ship. It therefore requires only a couple of tie
members 21 and 28 holding the channel members
25 and 26 in ?xed spaced relationship to complete
the assembly. These tie members or links 21 and
28 are, for the sake of economy, stamped from
sheet metal, which also permits easily twisting
these parts in the manner herein disclosed for
a quick and easy method of assembling, and
yet one which eliminates any likelihood of the
parts working loose afterward. The thought is 55,
2
2,129,637
to simply insert these fasteners crosswise through
the assembly and then twist the same so that the
crossheads a and b at opposite ends will be
brought closer together as a result of the twist
in the metal and accordingly force the channel
members 25 and 26 toward each other, the heads
b at the same time being moved out of register
with the slots through which they were previously
passed, so as to lock the parts in assembled rela
10 tion. A further thought is to have the crosshead
b‘ ride on inclined cam surfaces 29 in the twisting
of these fasteners whereby to not only give an
increased take-up in the matter of bringing the
members 25 and 26 together, but also provide
15 for such Variation in the amount of take-up as
may be found necessary or desirable in different
seat slide assemblies, due to slight discrepancies
in size and ?t of the parts as is apt to arise in
quantity production. Now it will be seen that the
keyhole slots 30 and 3! in the members 25 and 25,
respectively, must of necessity be large enough
to permit passing the head b‘ therethrough, and
that the head a must be slightly wider than the
head b in order that one end of the fasteners will
25 be anchored in the slots 30 when the other ends
are projected through the slots iii. The enlarge
ment 32 on the fasteners next to the heads a
serves to hold the fasteners at one end against
turning so that the other ends can be twisted.
30 The oppositely inclined cam formations on oppo
site sides of the slots 35, best illustrated in Fig. 8,
are formed by pressure between dies, and it is ob
vious that as the heads b are turned by means
of pliers or otherwise, one end of each head rides
35 outwardly on the one incline, while the other end
is riding outwardly on the other incline. That
accordingly quickly draws the member 2% in
wardly toward the member 25, and unneccesary
clearance between the parts l4-l5—25—26 is
40 eliminated, and only enough clearance is left for
easy working back and forth of the seat. The
workman quickly learns to gauge the twisting of
these fasteners 2'!—2B so as not to twist too far
and cause the seat slide parts to bind. If through
carelessness a fastener 21 or 28 is twisted too
much, the binding of the parts can be easily
remedied by turning one or both of the heads I)
back a tri?e. The fact that all unnecessary play
is eliminated naturally means that the seat slides
50 are not apt to rattle in service. If a rattle de
velops due to wear, the play can be taken up eas
ily by twisting the fasteners 2'|—28 a tri?e.
The only difference between the fasteners 2'!
and 28 is that the head a on the fastener 28 is
55 enlarged and perforated to provide a support for
the latch lever 2| as illustrated in Fig. 5.
