Description

[Detailed description of the invention] The present invention relates to a seat belt device for a vehicle.
In particular, it relates to the attachment structure of the buckle.

Generally, in a car, a seatbelt buckle that can engage with a tongue attached to the tip of the seatbelt is used to hold the occupant in the seat.
It is attached to the vehicle body via a handle member whose core material is wire and a bracket.

By the way, the part where the bracket is attached to the vehicle body is covered by the carpet laid inside the vehicle interior, but the part from the connection part between the bracket and the handle member to the seat belt buckle is arranged so as to protrude above the carpet. be done.

A pipe-shaped cover with a flange is fitted to the connecting portion in order to cover the connecting portion between the bracket and the handle member that protrudes above the carpet and the carpet notch.

However, in such a conventional vehicle seat belt buckle mounting structure, the cover can rotate freely at the joint between the bracket and the handle member, so the flange with the cover may shift from the carpet notch. , this may spoil the appearance.

It is also difficult to set the cover in place.

The present invention is an attempt to solve such problems, and when the base end of the handle member having a seatbelt buckle at the tip is connected and fixed to the cylindrical receiving part of the bracket by caulking, the cylindrical part of the bracket is The object of the present invention is to provide a vehicle seat belt buckle mounting structure that uses the caulking projection to prevent rotation of the cover, focusing on the fact that a caulking projection is formed on the shape receiving part. .

Therefore, the vehicle seat belt buckle attachment structure of the present invention has a bracket attached to the vehicle body, a handle member whose base end is inserted into the cylindrical receiving part of the bracket and connected and fixed by caulking, and a handle member with the same handle. A cover is provided with a seat belt buckle attached to the tip of the member, and has a cylindrical portion that fits into the cylindrical receiving portion of the bracket to cover the caulking protrusion formed on the outer periphery of the cylindrical receiving portion of the bracket. The present invention is characterized in that a cover rotation prevention groove that engages with the caulking projection is formed on the inner wall of the cylindrical portion of the cover.

Hereinafter, a vehicle seat belt buckle attachment structure as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a perspective view thereof, Fig. 2 is a sectional view of the main part thereof, and Fig. 3 is a caulking projection thereof. 4 is a sectional view taken along the - arrow in FIG. 3, FIG. 5 is a perspective view of the cover, and FIG. 6 is a perspective view showing the base end of the handle member. −
It is an arrow sectional view.

As shown in Figures 1 and 2, a bracket (metal fitting) 3 is attached to a bolt 4 and a nut 5 on the floor part B of the vehicle body.
It is tightened and fixed.

Further, the bracket 3 is formed with a cylindrical receiving part 3a into which the base end of the handle member 2 is inserted, and with the base end of the handle member 2 inserted into the cylindrical receiving part 3a, a required jig is inserted. The handle member 2 is connected and fixed to the bracket 3 by caulking using the handle.

The handle member 2 has a core made of a large number of wires and is covered with a rubber material or the like, and a seatbelt buckle 1 that can be engaged with a seatbelt tongue is attached to the tip of the handle member 2.

By the way, the bolted part of the bracket 3 is covered by the carpet 7 spread over the vehicle floor part B, but the upper part from the caulked part of the handle member 2 and the bracket 3 to the seat belt buckle 1 is It is located in the vehicle interior above the carpet 7 through the notch 7a of the carpet 7.

Therefore, in order to improve the appearance, it is necessary to cover up these caulked portions and the carpet cutout portion 7a. It is fitted into the cylindrical receiving portion 3a.

Note that this cover 6 is fitted onto the handle member 2 before the handle member 2 and the bracket 3 are caulked together.

Also, when connecting and fixing the handle member 2 and the bracket 3 by caulking, the cylindrical receiving part 3 of the bracket 3
On the outer periphery of a, as shown in Figs. 2 to 4, there is a pair of caulking projections (hereinafter referred to as "burrs") 3.
As shown in FIGS. 2, 5 and 6, a groove 6a that can engage with these burrs 3b is formed in the inner wall of the cylindrical portion 6c of the cover 6.

Therefore, the cylindrical portion 6c of the cover 6 is inserted into the bracket 3 so that the groove 6a engages with the burr 3b.
When the cover 6 is fitted into the cylindrical receiving part 3a, the burr 3b is covered and hidden by the cover 6, and rotation of the cover 6 is reliably prevented, so that the flange 6b of the cover 6 does not shift from the carpet notch 7a. do not have.

Further, although the cover 6 normally needs to be set in a predetermined position, if the burr 3b is formed in a predetermined position when crimping, the groove 6a of the cover 6 can be simply engaged with the burr 3b. , the above requirements can be realized.

Further, as shown in FIG. 5, the groove 6a is closed at the upper part of the cover 6, and this closed end functions as a stopper. As the cover 6 is pushed down, the cover 6 automatically stops, so the cover 6 can be attached accurately and easily.

Note that normally, the seat belt buckle 1, handle member 2, and bracket 3 are assembled together, and the cover 6 is also fitted to the handle member 2.
This assembly with cover 6 is attached to the vehicle floor part B so that the bracket part is under the carpet 7, and then the bracket 3 is removed by pushing down the cover 6 and engaging the groove 6a of the cover 6 with the burr 3b. The burr 3b and the carpet notch 7a formed on the outer periphery of the cylindrical receiving portion 3a are covered.

As detailed above, according to the vehicle seat belt buckle attachment structure of the present invention, the base end is inserted into the cylindrical receiving part of the bracket attached to the vehicle body and the buckle is connected and fixed by caulking. A cylindrical seat belt comprising a handle member and a seat belt buckle attached to the tip of the handle member, and that fits into the cylindrical receiver part of the bracket to cover the caulking protrusion formed on the outer periphery of the cylindrical receiver part. It has a simple structure in which a cover with a cylindrical part is provided, and a cover rotation prevention groove that engages with the caulking protrusion is formed on the inner wall of the cylindrical part of the cover. Free rotation in the receiving portion can be prevented, which has the advantage that the cover can be easily and reliably attached to a predetermined position.
