VEHICLE SEAT TRIM COVER RETAINER
BACKGROUND OF THE I N'~'T~N
The present invention relates to securing
a vehicle seatback trim cover to a portion of the
seatback frame, and more particularly, to a
a
retainer for securing two ends of a trim cover to
a frame at a single location.
With reference to FIG. 1, in a vehicle
seatback 10 incorporating a child seat module 12,
the module 12 is typically disposed between two
bolster portions 14 and,l6 of the vehicle seatback
10. A trim cover 18 is fitted over the respective
bolster portions. Each end of the trim cover 18
includes a conventional rope listing 20 sewn
thereto which is used to secure the trim cover to
the frame.
As shown in FIG. 1, to cover bolster
portion 14 with the trim cover 18, one end of the
trim cover 18 is disposed adjacent a portion 22 of
the frame. The trim cover 18 is then wrapped
around a peripheral surface of the bolster portion
14 such that the ends of the trim cover are
disposed generally adjacent to each other.
Conventional hog rings 24 are then used to fix the
rope listing ends of the trim cover to the frame
portion 22.
The hog rings 24 are typically delivered
using conventional air-operated devices, whereby
manual actuation of a trigger delivers and secures
the hog ring at the desired location. Such
devices, however, are cumbersome, often weighing a
few pounds or more. It has been found that

WO 96124275 218 7 3 4 2 PCT/US96100829
continuous handling of the device and repeated
actuation of the trigger during the assembly
procedure may lead to operator injury, such as the
development of carpal tunnel. Further, when using
conventional hog rings in the assembly, it is ,
difficult to perform any required adjustment of
the trim cover once secured to the frame.
Accordingly, it can be appreciated that a
need exists to provide a simple and cost effective
way of securing a trim cover to a seatback frame
which overcomes the inadequacies of the
conventional methods.
5~i~lRY OF THE INVENTION

DETAIr_.gD DESCRIPTION OF THE
pRES NmT pREF RED EX Mp ARV EMBODrbiENT
Referring to the drawings, a retainer is
shown, generally indicated at 100, which embodies
the principles of the present invention.
The retainer 100 includes a first
elongate body 112 having a curved base portion 114
and first and second respective arms 116, 118,
extending in spaced relation from the base portion
114 so as to define a generally U-shaped or open-
ended channel 120 therebetween. A planar portion
122 extends from the first arm 116 in parallel
relation with the second arm 118. Barbs 124
extend from each of thefirst and second arms 116,
118 into the channel 120. The barbs 124 are in
opposing relation and define retaining structure
constructed and arranged to retain an object
received in the U-shaped channel 120. As shown in
FIG. 3, each barb 124 includes a caroming surface
126 which helps direct an object being inserted
into the U-shaped channel 120.
- 5 -

WO 96/24275 2 ~ 8 7 3 4 2 PCT/US96/00829
The retainer 100 includes a second
elongate body 128 having a curved base portion 130
and first and second respective arms 132, 134
extending in spaced relation from the base portion
130. The arms 132 and 134 define a second, ,
generally U-shaped or open-ended channel 136
therebetween. The second arm 132 of the second ,
body 128 is coupled to the first body 112 in such
a manner that a longitudinal axis A of the first
body is in parallel relation with a longitudinal
axis B of the second body. Further, an open-end
of the first channel 120 is oriented at an angle
of at least 180° with respect to the open end of
the second channel 136.
In the illustrated embodiment (FIG. 3),
the second arm 132 of the second body 128 is
disposed at an angle C of approximately 45° with
respect to the first arm 116 of the first body
112, such that the open end of the second channel
1'36 is oriented at an angle D of approximately
225°from the open end of the first channel 120,
the function of which will become apparent below.
The second body 128 includes barbs 142
(FIG. 3) extending from each of the first and
second arms thereof into channel 136, which, like
the barbs 124 of first body, define retaining
structure constructed and arranged to retain an
object received in the U-shaped channel 136 of the
second body 128. Further, the second body 128
includes a caroming surface-144 defined at a distal
end of the first arm thereof for directing an
object into the second channel 136.
Preferably, the retainer 100 is formed
integrally from resilient, plastic material such
- 6 -

R'O 96124275 21 8 7 2 PCT~S96100829
3
4
as, for example, polyproplene, or similar
material. The retainer 100 must be
rigid enough
to provide a retaining function, yet
permit a trim
cover to be sewn to the planar portion
thereof, as
. 5 will be explained below. The overall
length of
the retainer 100 is not critical and
may be
adapted for the particular assembly
required.
The use of the retainer 100 in fastening
ends of a trim cover 146 to a portion
of a vehicle
seatback frame will be appreciated
with reference
to FIG. 4 and from the discussion below.
First, the trim cover 146 is prepared
by
l
sewing a conventional, resilient
flange member
152, for example, profile number P-821
manufactured by Bemis, to the second
end 150
thereof. The first end 148 of the trim
cover 146
is folded-over upon the trim cover
and sewn to the
planar portion 122 of the retainer
100. Next, the
retainer 100 is snapped onto a generally
cylindrical rod member 23, which is
coupled to the
seatback frame and extends vertically
therefrom.
The rod member 23 is received in the
first channel
120 of the retainer 100 and held therein
by the
barbs 124. The second end 150 of the
trim cover
146 is then moved about a peripheral
surface of
the bolster portion 14 of the vehicle
seatback in
the direction of arrow E in FIG. 4,
until the
second end 150 is disposed generally
adjacent to
the first end 148. Since the second
channel 136
opens in a direction generally opposite
to the
direction in which the first channel
120 opens,
the resilient flange member 152 may
then be
inserted into the second channel 136
of the
retainer and held therein by the barbs
142
thereof.

WO 96/24275 218 7 3 4 2 pC'p'/17596/00829
Thus, it can be appreciated that the two
ends of the trim cover 146 may be coupled to the
frame at a single location. In securing the ends
of the trim cover to the vehicle seatback frame,
there is no need to use hog rings or the air-
operated device associated therewith, since the
retainer of the invention permits a manual
assembly procedure, requiring no special tools.
Further, since the retainer 100 merely snaps onto
the rod member 23 of the frame, and the resilient
flange member 152 is simply pushed into the second
U-shaped channel 136, an adjustment of the trim
cover 146 may be performed easily if required.
Such adjustment is possible since the retainer can
be moved with respect to-the rod member and/or the
flange member can be moved with respect to the
retainer.
It can be seen that the retainer of the
present invention provides an effective means of
coupling ends of a trim cover to a portion of the
frame at one location. Since the use of the
retainer requires no tools, the likelihood of
operator injury is decreased, and the assembly
time is substantially reduced.
While the invention has been described in
connection with what is presently considered to be
the most practical and preferred embodiment, it is
understood that the invention is not limited to
the disclosed embodiment, but, on the contrary, is
intended to cover various modification and
equivalent arrangements included with the spirit
and scope of the appended claims.
