ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a shoulder anchor position adjusting device which adjusts the position of a shoulder anchor of a seat belt device.
2. Description of the Related Art
In general, for convenience of use of a seat belt, as illustrated in
FIGS. 5 and 6
, a shoulder anchor
12
which is a part of a seat belt device is mounted to a center pillar within a vehicle via a shoulder anchor position adjusting device
10
for adjusting the position of the shoulder anchor
12
.
Specifically, the shoulder anchor position adjusting device
10
includes a slider
14
, a slide rail
16
, and a lock pin
20
. The shoulder anchor
12
, through which a webbing W is inserted, is mounted to the slider
14
. The slider
14
is attached to the slide rail
16
so as to be able to slide therealong. The lock pin
20
can be fit into an engagement hole
18
formed in the slide rail
16
.
The lock pin
20
is shaft-supported by a pin
24
at a release lever
22
. A pin
25
which is provided at an intermediate portion of the release lever
22
is shaft-supported by shaft receiving portions
26
formed on the slider
14
, such that the release lever
22
is swingable.
In this structure, by swinging the release lever
22
in a predetermined direction, the lock pin
20
which is inserted through a hole
27
is engaged with the engagement hole
18
or the engaged state thereof is released, such that the slider
14
is locked or becomes slidable.
However, in the above-described structure, in order to assemble the lock pin
20
to the release lever
22
, holes through which the pin
24
is inserted are formed in the release lever
22
. In the state in which the lock pin
20
is disposed at a predetermined position of the release lever
22
, the pin
24
passes through the aforementioned holes, and thereafter, the special working of crushing both end portions of the pin
24
with a press is required in order to prevent the pin
24
from coming out of the holes. Further, another special working is required to form at the slider
14
the shaft receiving portions
26
which shaft-support the release lever
22
.
SUMMARY OF THE INVENTION
In view of the aforementioned, an object of the present invention is to provide a shoulder anchor position adjusting device in which the assembly of a shoulder anchor position adjusting mechanism is easy and does not require special workings such as those described above.
A first aspect of the present invention is a shoulder anchor position adjusting device comprising: a slider to which a shoulder anchor, through which a webbing is inserted, is mounted; a slide rail which is fixed to a vehicle body and to which the slider is slidably mounted; a lever in which a receiving portion is formed and which is swingably disposed on the slider, an opening corresponding to an insertion hole formed in the slider being formed in the receiving portion; a lock pin at which a flange portion which is supported at the receiving portion of the lever is formed, and which is inserted into the insertion hole of the slider, and which can fit into and be removed from an engagement hole formed in the slide rail due to swinging operation of the lever; and a cover case which covers the slider and swingably holds the lever.
In accordance with the above-described structure, the shoulder anchor, through which the webbing is inserted, is mounted to the slider, and the slider is slidably mounted to the slide rail.
The lever is swingably placed on the slider. A receiving portion, in which an opening is formed, is formed at the lever. This opening corresponds to the insertion hole formed in the slider.
The flange portion of the lock pin is supported at the receiving portion of the lever. Due to urging force of the urging means, the lock pin is inserted through the insertion hole of the slider from the opening of the lever, and is fit into the engagement hole of the slide rail. Further, the cover case covers the slider, and swingably holds the lever. When the lever is swung in a predetermined direction, the lock pin is pulled out of the engagement hole such that the slide becomes slidable.
As described above, because the flange portion of the lock pin is supported at the receiving portion of the lever, when the lock pin and the lever are being assembled, there is no need for special working for assembling the lock pin to the lever, as there is in conventional structures. Further, because the lever is held swingably on the slider by the cover case, there is no need to subject the slider to special working, such as forming a holding member for holding the lever. Accordingly, the number of processes involved in assembly is decreased, and the shoulder anchor position adjusting mechanism can be assembled easily.
In a second aspect of the present invention, an anchor plate is formed at the cover case, and the anchor plate engages with a groove formed in the lever.
In accordance with this structure, the anchor plate formed at the cover case engages with the groove formed in the lever, and the lever can thereby be held on the slider and is swingable on the slider.
It is preferable that that lever is formed so as to be substantially V-shaped as viewed from above.
The shoulder anchor position adjusting device of the present invention may further comprise urging means for urging the lock pin in a direction of fitting-in into the engagement hole.
A third aspect of the present invention is a shoulder anchor position adjusting device comprising: a shoulder anchor position adjusting device comprising: a slider to which a shoulder anchor, through which a webbing is inserted, is mounted; a slide rail which is fixed to a vehicle body and to which the slider is slidably mounted; a lever in which an opening corresponding to an insertion hole formed in the slider is formed; and a lock pin inserted through the insertion hole via the opening, and able to be fit into and removed from an engagement hole formed in the slide rail, wherein a supported portion formed at the lock pin is removably supported at a lock pin supporting portion formed at the lever.
The supported portion may be a projecting portion which extends substantially perpendicular to an axial direction of the lock pin.
Further, at least one portion of the lock pin supporting portion may be formed so as to correspond to a configuration of the projecting portion.
A fourth aspect of the present invention is a shoulder anchor position adjusting device comprising: a shoulder anchor position adjusting device comprising: a slider to which a shoulder anchor, through which a webbing is inserted, is mounted; a slide rail which is fixed to a vehicle body and to which the slider is slidably mounted; a lever in which an opening corresponding to an insertion hole formed in the slider is formed; a lock pin inserted through the insertion hole via the opening, and able to be fit into and removed from an engagement hole formed in the slide rail; and a case member formed on the slider, wherein a groove portion is formed in the lever, and due to an anchor portion formed at the case member engaging with the groove portion, the lever is swingably held on the slider.
