Description
Field of the Invention
This invention relates to an adjustable anchor
device, particularly to an adjustable shoulder anchor device for a shoulder belt which restrains the
upper body of a rider in a vehicle.
5
Background of the Invention
io
In conventional seat belt devices such as the
three point seat belt devices which are used in
vehicles, a shoulder anchor device is used in order
to make it possible for the seat belt to fit passengers of different bodily builds, who assume
different postures while driving. The shoulder anchor device makes it possible to adjust the support
or attachment position where the shoulder belt for
restraining the upper body is attached to the vehicle on the shoulder side. Normally the support or
attachment position is adjusted vertically, so that
the support position of the shoulder belt is prevented from being moved or shifted in, for example, a vehicle collision.
In Figs. 1 to 3 which show this kind of conventional anchor device, an adjustment base 1 is fixed
to, for example, a center pillar of the vehicle body
(not shown) in its longitudinal direction (up-down
direction of the vehicle body). An adjustable anchor
2 is attached to the adjustment base 1 so that it
can move in the vehicle's up-down direction. The
adjustable anchor or runner 2 cannot move in the
longitudinal direction of the adjustment base or
guiding member 1 when the lock pin 3 is mated
with one of the engaging openings 6 which are
provided at specified intervals in that direction;
when the pin is pulled out from the hole, it can
move. Fixed to the adjustable anchor 2 through
some means such as coupling is a through-anchor
4 through which a shoulder belt 5 passes.
It is known that the input load applied to the
shoulder belt 5 can reach as much as two tons
during a vehicle collision. For this reason, in order
to ensure that the shoulder belt will be strong
enough to perform reliably in such an emergency,
the anchor device must be sufficiently strong in the
input transmission path to the vehicle side. This is
one of the most important design requirments.
Now, the construction of conventional anchor
devices, particularly the adjustable anchor 2 is explained with reference to the transmission of the
shock force.
A shock is input from the shoulder belt 5
through the through-anchor 4 in the X or X' direction in Fig. 1, transmitted to the adjustable anchor
2, and then through the lock pin 3 to the adjustment base 1. Consequently, since an anchor bolt 8
75
20
25
30
35
40
45
50
55
2
2
is used in order that the adjustable anchor 2 is
securely coupled to the through-anchor 4 through
which the shoulder belt 5 passes, it is necessary
for the attachment strength of the anchor bolt 8 to
be maintained sufficiently strong to resist the
shock. The strength of the attachment of the lock
pin 3 to the adjustable anchor 2 also must be
adequate in order for the load to be transmitted to
the adjustment base 1 without difficulty.
In addition, the construction or strength of the
adjustable anchor 2 must be focussed. Supposing
that the adjustable anchor 2 becomes deformed,
the lock pin 3 will be displaced relative to the
adjustment base 1 and the pin will be released
from its coupling to the adjustment base 1, resulting in that the effectiveness of restraint of the
passenger is greatly reduced or lost in the adjustable anchor device. Therefor, it is important for
both the strength of the adjustable anchor 2 itself
and the coupling of the lock pin 3 to the adjustable
anchor 2 to be adequate.
In order to overcome these requirements, and
make it easy to adjust the position of the adjustable
anchor 2, the adjustable anchor 2 in an improvement has opposing arms 2a and 2b on its rear side
to form a square C shape in cross section which
can maintain a cross-sectional area enough to keep
the attachment strength, shown in Fig.3. Using this
shape, the through anchor 4 fastened by the anchor bolt 8, and the design permits the lock pin 3
to be supported by the upper and lower side portions of the G-shaped adjustable anchor 2. Then by
moving the lock pin 3 from the upper side portion
to the lower one or from the lower side portion to
the upper one, the lock pin 3 becomes coupled to
or decoupled from the engaging opening 6 of the
adjustment base 1. Accordingly, the C-shaped adjustable anchor 2 can move along the adjustment
base 1, in the vertical or up-down direction relative
to the vehicle, with its inner surfaces sliding on the
adjustment base 1. Thus the movement of the Cshaped adjustable anchor 2 can be made only
when the lock pin 3 is decoupled from the adjustment base 1.
However, when the space inside the vehicle
cabin is limited, it can become impossible for the
adjustable anchor 2 to have the necessary crosssectional area. Accordingly, some measures must
be taken to compensate for; for example, increasing the plate thickness of the adjustable anchor 2,
using stronger material for the adjustable anchor 2,
using induction hardening to increase the surface
hardness of the section of the adjustable ancohor 2
to which the lock pin 3 is coupled, or forming the
adjustable anchor 2 in a closed square shape. All
of these measures increase weight and/or cost.
An adjustable anchor device as described
above is disclosed in GB-A-2 176 091.

EP 0 315 989 B1
The purpose of this invention is to solve the
aforesaid problems and to provide a more highly
reliable adjustable anchor device without sacrificing
vehicle space.
Summary of the Invention
The present invention is as defined in the accompanying Claim 1 that has been divided into a
two part form based on the assumption that GB-A2 176 091 is the nearest prior art. In the accompanying Claim 1 the adjustable anchor 2 of the
aforesaid prior art is characterized in that means
are provided on said adjustable anchor 2 for preventing its open side from expanding out.
Even when a device having the construction is
subjected to a large shock input, as for example
during a vehicle collision, adequate strength of the
adjustable anchor is maintained due to the interlocking means for preventing the adjustable anchor
from being deformed, so that the lock pin is not
displaced relative to the adjustment base. There is
no problem such that the adjustable anchor does
suddenly become uncoupled.

Description of the Preferred Embodiments
An adjustable shoulder anchor device utilizing
the present invention will now be explained using
the embodiments shown in the drawings, in which
like reference numerals are used to indicate like
members throughout the drawings.
Fig.5 shows a first embodiment of this invention, and Fig.6 shows details of section B in Fig.5.
The adjustable anchor 2 is formed in a C-shape in
cross-section, and has opposing arms 2a and 2b
50
55
3
4
which extend inwardly from the lateral sides in a
similar manner to that of Fig.3, but the arms 2a and
2b of the C-shaped anchor are coupled to each
other in its center section through an interlocking
construction. Specifically, the arm 2a has a convex
portion or projection 10a, while the arm 2b has a
concave portion or recess 10b to receive the convex portion or projection 10a in a nest shape. The
convex portion or projection 10a is made divergent
toward the concave portion or recess 10b. Since
the arms 2a and 2b of the adjustable anchor 2 is
thus coupled to form a box-like structure, then even
if a large shock input, such as that received during
a vehicle collision, is received in the X or X'
direction as in Fig.1, the stress or tension can be
efficiently dissipated, so that the convex portion or
projection 10a could not be pulled out from the
concave portion or recess 10b even under a high
tension upon collision. In other words, since the
arms 2a and 2b of the adjustable anchor 2 in the
open or C cross-section shape is not expanded or
separated from each other, the circumference of
the lock pin 3 is not deformed under such a high
tension.
In Fig.7 and Fig.8 which show the second and
third embodiments, the only difference from the
first embodiment is the shape of the interlocking
means comprising the convex portion or projection
10a and the concave portion or recess 10b. Specifically, the convex portion or projection 10a in the
second embodiment has a T-shape with the complementary shape in the concave portion or recess
10b, and the convex portion or projection 10a in
the third embodiment has a L-shape with the complementary shape in the concave portion or recess
10b, wherein the lower portion of the T-shaped
projection 10a is connected to the arm 2a, and the
lower portion of the L-shaped projection 10a is
embeded in the arm 2b. These shapes also are
formed to be against the force which is inclined to
separate the convex portion or projection 10a and
the concave portion or recess 10b from each other.
In the second and third embodiments, there is a
clearance t in the interlocking means; this can be
made to have a very small value by careful control
of the precision of machining and assembly of the
adjustable anchor 2. The device functions in the
same way as in the first embodiment.
Fig.9 shows a fourth embodiment of the subject invention, which further has an interlocking
structure provided at the upper corner of the convex section near the hole for receiving the lock pin
3. Specifically, a convex portion or projection 12a
is provided at the upper corner of the convex
section in the arm 2b, while a concave portion or
recess 12b in the complementary shape provided
in the arm 2a. Since the convex portion or projection 12a is projected in a direction orthogonal to the
5
EP 0 315 989 B1
separating force between the arms 2a and 2b, the
convex portion or projection 12a in a simple shape
can be against the separating force. This also helps
to prevent the rear side of the adjustable anchor 2
from opening at the corner near the lock pin 3. It
will be noted that there are a pair of retaining
structures 12a,12b and 10a,19b above and below
the lock pin 3 in this embodiment. Consequently,
the lock pin is positively secured to the adjustment
base 1 at a predetermined position.
In the configuration described above, a highly
reliable adjustable anchor device is obtained at low
weight and low cost, with efficient use of space. In
particular, it is not necessary to use a special
material such as high tension steel plate; at the
same time the member plate thickness can be
made thin and it becomes unnecessary to apply
heat treatment or other special treatment.
Other modifications could be made possible for
those skilled in the art within the scope of the
present invention.
