ABSTRACT:
TECHNICAL FIELD
The present invention relates to a seat belt anchorage plate for a seat belt device for attaching the end of, for example, a seat belt for an automobile to a fixed part such as a vehicle body.
BACKGROUND ART
Conventionally, as such kind of seat belt anchorage plate, a plate illustrated in
FIG. 38
has been well known. That is, a seat belt anchorage plate comprises a base (plate shaped member)
2
having a bolt hole
3
and a slot
69
formed thereon and is designed to be secured to a fixed part such as a vehicle body through the bolt hole
3
and to be connected to a belt
13
through the slot
69
.
The belt
13
employs a thin band shaped woven fabric in which for example, polyester fibers are woven and is folded back in one long edge part
691
-
8
of the slot
69
, so that tension is exerted on the one long edge part
691
-
8
which is linearly formed.
Since the above mentioned conventional seat belt anchorage plate has one long edge part
691
-
8
formed in a straight line, when the tension of the belt
13
is not exerted in the direction perpendicular to the one long edge part
691
-
8
, the belt
13
is liable to laterally slide on the one long edge part
691
-
8
and come together to the end part of the long edge part
691
-
8
. In other words, there has been encountered a problem that the belt is apt to be gathered to the end part of one long edge part
691
-
8
. Even if the tension of the belt
13
is exerted in the direction perpendicular to the one long edge part
691
-
8
, for example, according to an examination through a strength measuring test, the belt
13
itself will be thinly converged and tend to meet at one part on the one long edge part
691
-
8
when the tension is exerted on the belt
13
. Further, since the one long edge part
691
-
8
is elastically bent and slightly recessed by virtue of the tension of the belt
13
, the belt
13
is undesirably liable to be gathered to one part on the long edge part
691
-
8
in addition to the defect that the belt
13
itself thinly converges into one part.
Further, the belt
13
is advantageously curved so as to be folded along a center line in its longitudinal direction in order to maintain the flat state of the belt
13
. Therefore, the belt
13
is normally inserted into the slot
69
under its curved state as stated above. However, when the belt
13
is curved in such a way, there arises a problem that both ends at the right and left sides of the belt
13
abut against, for example, both right and left ends of the one long edge part
691
-
8
, and therefore, the belt
13
is inserted into the slot
69
with difficulty. As shown in
FIG. 38
, when both the end parts of the belt
13
swell out roundly, there also arises a problem that these swelling parts tend to more easily abut against both the end parts of one long edge part
691
-
8
.
Still further, the slot
69
is formed by a press working. In this case, burs are liable to be formed at the corner parts in the side punched out by a press. When such burs are left as they are, they have possibility to cause an action similar to that of a cutter. Accordingly, the corner parts are ordinarily subjected to a rounding finish independent of a press working process, or a coating works to cover the entire corner parts with vinyl chloride or polyethylene or the like. As a result, there has been encountered a problem in terms of cost-up owing to such a finishing work or a coating work.
Additionally stated, as illustrated in
FIG. 39
, since a seat belt anchorage plate is formed with a plate shaped base
2
, the area of one long edge part
691
-
8
for holding the belt
13
is small, so that surface pressure exerting on the belt
13
is disadvantageously increased.
The present invention was made by taking these problems into account and an object of the present invention is to provide a seat belt anchorage plate for a seat belt device and a method for manufacturing it capable of completely reducing surface pressure to be exerted on the belt even when tension acts on the belt.
DISCLOSURE OF INVENTION
In order to achieve the above described object, a feature of the invention is a seat belt anchorage plate for a seat belt device which is formed with a plate shaped member, the plate shaped member having a slot formed into which the belt is inserted; the slot having long edge parts opposed to each other one of which bears the tension of the belt folded back therein; and one of the long edge parts being formed to expand toward a central part from both end parts in its longitudinal direction.
The Invention also concerns a seat belt anchorage plate for a seat belt device formed with a plate shaped member having a slot into which the belt is inserted and which has long edge parts opposed to each other, the belt being folded back in one of the long edge parts so that the one long edge part bears the tension of the belt, wherein the one long edge part is formed so as to swell in the direction opposite to that of the tension of the belt toward a central part from both end parts in its longitudinal direction.
Another feature of the invention concerns the other long edge part opposed to the one long edge part being formed so as to extend along the one long edge part.
The invention also concerns the one long edge part being formed so that it is provided with a protrusion protruding from one surface of the plate shaped member and its cornerparts are rounded along the direction in which the belt is folded back.
The invention concerns the one long edge part being formed so as to have a protrusion which protrudes from the other side of the plate shaped member by bending a part of the plate shaped member from one surface side to the other surface side so that an area against which the belt abuts is increased and corner parts are rounded along the direction in which the belt is folded back due to the existence of the protrusion.
Another feature of the invention is the long edge part being formed so as to have one protrusion and the other protrusion respectively protruding from one surface and the other surface of the plate shaped member and their corner parts are rounded.
The invention also concerns the one long edge part being formed so as to have one protrusion and the other protrusion respectively protruding from one surface side and the other surface side of the plate shaped member by bending a part of the plate shaped member from one surface side to the other surface side of the plate shaped member and pressing the bent part to return to the one surface side, so that an area against which the belt abuts is increased owing to the one protrusion and the other protrusion, and further, their corner parts are rounded along the direction on which the belt is folded back.
The invention includes short edge parts except the one long edge part in the slot for connecting at least one long edge part to the other long edge part are formed so as to have a protrusion similar to that of the one long edge part.
The invention includes short curved edges for connecting the one long edge part to the other long edge part.
The invention includes a seat belt anchorage plate for a seat belt device formed with a plate shaped member, the plate shaped member having a slot formed thereon into which the belt is inserted; the slot having long edge parts opposed to each other, the belt being folded back in one of the long edge parts which bears the tension of the belt; and the one long edge part having a protrusion which protrudes from at least one surface of the one surface and the other surface of the plate shaped member.
The includes short edge parts except the one long edge part in the slot for connecting at least one long edge part to the other long edge part are formed so as to have a protrusion similar to that of the one long edge part.
Another feature of the invention includes the one long edge part having corner parts rounded along the direction in which the belt is folded back.
The invention includes respective protrusions having the amount of protrusion from the plate shaped member rangi
