Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillar garnish for covering an airbag of a side airbag device which is folded and stored around an opening such as the periphery of a door of a motor vehicle. The present invention relates to a pillar garnish provided with a cap for covering a fixing means used for attaching and fixing to a pillar garnish.

[0002]

2. Description of the Related Art Conventionally, in this type of side airbag device, an airbag is folded and stored over a pillar portion and a roof side rail portion at an opening edge of a door or a window inside a vehicle. When the inflation gas flows into the bag, the airbag cover (pillar garnish) covering the folded airbag is opened to expand and inflate the airbag (Japanese Patent Laid-Open No. 9-31525).
No. 3).

[0003] In the side airbag device,
In order to prevent the pillar garnish being pushed when the airbag is deployed and inflated, the pillar garnish must be firmly fixed to the body. Therefore, using fixing means such as mounting bolts that are fastened to the body from the inside of the vehicle,
A configuration in which the pillar garnish is attached and fixed to the body is conceivable. In that case, it is preferable to dispose a cap on the garnish main body in order to hide the fixing means from the viewpoint of design.

However, when increasing the output of an inflator for supplying an inflation gas to the airbag so that the airbag is quickly protruded, the garnish body is suddenly pushed by the airbag and opened or moved. It is necessary to connect the cap so that the cap does not come off from the garnish main body.For example, the cap itself can be locked with a high locking force against a locking hole provided in the garnish main body. It becomes necessary to provide a retaining portion.
That is, the outer diameter of the locking portion to be locked is increased with respect to the inner diameter of the locking hole provided in the garnish body,
It is necessary to increase the difference in the dimensions, that is, the amount of undercut.

[0005] However, such a locking portion integral with the cap is inserted into the locking hole of the garnish main body of the airbag cover to which the cap is connected, from the removal direction, so that the garnish main body is connected to the cap. Because it is a mode to lock, it is difficult to secure a large undercut amount,
It was difficult to obtain a high locking force. This is because, if it is configured to secure a high locking force, that is, to secure a large amount of undercut, it becomes difficult to insert the locking portion into the locking hole, and the cap itself is connected to the garnish body. This is because it takes time, or connection becomes impossible.

An object of the present invention is to provide a pillar garnish in which the cap can be easily connected to the garnish main body without causing a risk of detachment.

[0007]

A pillar garnish according to the present invention is arranged so as to cover an airbag folded around an opening on the inside of a vehicle so that the airbag can protrude when the airbag is deployed and inflated. A garnish body attached to and fixed to the body by fixing means fixed to the body from the inside of the vehicle while being deformed by being pushed by the airbag, and a cap disposed on the garnish body so as to hide the fixing means. Wherein the cap comprises: a lid body covering the fixing means; and a retaining member assembled to the lid body, wherein the retaining member comprises the lid body. A locking portion that can be mounted and locked to the vehicle, a shaft portion extending from the mounting locking portion, and a bulging locking portion bulged in a radial direction at a tip of the shaft portion. The garnish body is provided with a locking hole having an inner diameter that allows the assembly locking portion and the shaft portion to pass therethrough, and the bulging locking portion and the lid body to be unable to pass through. The cap is connected to the garnish main body by inserting the mounting locking portion of the retaining member through the locking hole and mounting and locking the mounting locking portion to the lid main body. It is characterized by.

[0008] It is preferable that the bulging engagement portion is formed to have a large diameter in a tapered shape from the shaft portion.

[0009]

According to the pillar garnish according to the present invention,
The cap is inserted into the locking hole of the retaining member through the locking hole, and the mounting locking portion is mounted and locked to the lid body,
It is connected to the garnish body.

After the garnish main body is fixed to the body by fixing means so as to cover the folded airbag, and after the lid main body of the cap is arranged at a predetermined position so as to hide the fixing means, the air is removed. When the bag is deployed and inflated, even if the garnish body is pushed by the airbag and deforms greatly, and the periphery of the locking hole is deformed, the shaft of the retaining member inserted through the locking hole of the garnish body is deformed. Since both ends are the swelling engagement portion larger than the inner diameter of the engagement hole and the lid main body, there is no possibility that the cap is detached from the garnish main body.

Further, since a large force is not directly applied to the assembly portion of the cap between the lid main body and the retaining member as compared with the garnish main body which receives a large deformation force when the airbag is inflated, the lid main body and the retaining member are prevented from coming off. It is unlikely that assembly with the member will be released.

Therefore, in the locking relationship between the attachment locking portion of the retaining member and the lid main body, even if the amount of undercut is small, there is little possibility that the assembly of the lid main body and the retaining member is released. Therefore, the amount of undercut can be reduced, and the assembly locking portion of the retaining member can be easily assembled to the lid main body through the locking hole of the garnish main body.

Therefore, in the pillar garnish according to the present invention, the cap can be easily connected to the garnish main body without causing a risk of detachment.

If the swelling engagement portion is formed so as to have a large diameter in a tapered shape from the shaft portion, the following operation and effect can be obtained.

That is, when the cap is about to come off from the garnish main body, the pressing force acting on the periphery of the locking hole of the garnish main body is smaller than that of the garnish main body, as compared with the case where the bulging locking part side is separated from the garnish main body. It has a great effect when the heavy lid body side moves away from the garnish body. Therefore, even when the swelling locking portion of the retaining member comes into contact with the periphery of the locking hole with the deployment and inflation of the airbag, the swelling locking portion does not suddenly have a large diameter, and the shaft portion and Since the bulging locking portion does not suddenly have a large diameter such that stress concentration is likely to occur at the boundary portion with the bulging locking portion, there is no possibility that the bulging locking portion may be damaged, and The cap can be prevented from coming off the garnish body.

Then, a predetermined mounting bracket 54
If the mounting bolts 55 are temporarily assembled, the airbag assembly A can be assembled.

Thereafter, the airbag assembly A is attached to the body 1 by attaching the mounting bracket 36 to the side panel 2 using the mounting bolt 37 as shown in FIGS.
Mounting holes 54c, 52a, 7g
9a so that each mounting bracket 54
Are arranged on the inner panel 7 of the pillar body 4 and the roof side rail body 9, and the mounting bolts 55 are screwed into the nuts 7h and 9b via the mounting holes 52a and 54c, respectively.

After the airbag assembly A is attached to the body 1, the lead wire 39a is connected to a predetermined airbag operating circuit, and as shown in FIGS. The garnish body 12 is attached and fixed to the inner panel 7, and the roof interior material 31 is assembled to a predetermined portion of the body 1 at the roof side rail portion R so as to cover the airbag assembly A.

The garnish body 12 is fixedly attached to the inner panel 7 by inserting the locking portion 21c of the locking pin 21 from the wide portion 7e in the locking hole 7d (see the two-dot chain line in FIG. 11).
1cP), the locking portion 21c is shifted to the narrow width portion 7f side (shifted to the position indicated by the solid line in FIG. 11), and the locking leg 17 is inserted and locked in the locking hole 7c. Further, the mounting bolt 29 is screwed into the nut 7b constituting the mounting hole 7a via the sleeve 15 fitted on the inner peripheral surface of the mounting hole 13a of the mounting boss portion 13, and then connected to the garnish body 12 in advance. The fitting operation can be completed by engaging the locking claw 26b with the locking groove 29b of the bolt 29 while fitting the cap 25 that has been set into the storage recess 14.

When the inflator 39 is actuated after the side airbag device M is mounted on the vehicle, inflation gas flows into the bag portion 43 of the airbag body 42 of the airbag 41, Inflow part 43d and expansion part 4
3c expands to break the tape material 57, and the pillar garnish 11 of the pillar portion PF is
2, the locking leg 17 is disengaged from the locking hole 7c as shown by the two-dot chain line in FIGS.
The first locking portion 21c is slid along the front pillar portion PF to a position indicated by a two-dot chain line 21cB in FIG. 11 so that a substantially vertical intermediate portion of the pillar garnish 11 is separated from the inner panel 7. The door 12d is opened while moving to the inside of the vehicle, and the roof interior material 31 of the roof side rail portion R is pushed by the airbag body 42, and as shown by the two-dot chain line in FIG. 3

At that time, the garnish body 12
The locking leg 17 is bent so as to separate from the inner panel 7, or the door 12d is opened, and greatly deformed.
As shown by the two-dot chain line in FIG. 8, even if the cap 25 releases the locking claw 26 b from the periphery of the locking groove 29 b of the mounting bolt 29 and tries to come off the garnish body 12, The two ends of the shaft portion 27d of the retaining member 27 passing through the locking holes 14a of the
Since the swelling engagement portion 27e and the lid main body 26 are larger than the inner diameter dimension D0 of 4a, there is no possibility that the cap 25 comes off the garnish main body 12.

Further, since a large force is not directly applied to the assembly portion of the cap 25 where the lid main body 26 and the retaining member 27 are attached, compared with the garnish main body 12 which receives a large deformation force when the airbag is inflated, the lid 25 is closed. It is unlikely that the assembly of the main body 26 and the retaining member 27 will be released.

For this reason, in the locking relationship between the attachment locking portion 27a of the retaining member 27 and the attachment portion 26c of the lid main body 26, even if the undercut amount X (d1−d0) is small, it is not possible to remove the lid main body 26. Since it is unlikely that the assembly with the stopper member 27 will be released, the undercut amount X can be reduced, and the attachment locking portion 2 of the retaining member 27 can be reduced.
7a can be easily assembled to the assembly portion 26c of the lid main body 26.

Therefore, in the pillar garnish 11 of the embodiment, the cap 25 can be easily connected to the garnish main body 12 without causing a risk of detachment.

In the embodiment, the swelling engagement portion 27e
Are formed to have a large diameter in a tapered shape from the shaft portion 27d. Therefore, when the cap 25 is about to come off from the garnish body 12, the pressing force acting on the periphery of the locking hole 14a is such that the bulging locking portion 27e side has
As shown by the two-dot chain line in FIG. 8, the lid body 26, which is heavier than the retaining member 27, acts more when the lid body 26 is separated from the garnish body 12 than in the case where it is separated from the garnish body 12. In addition, even if the bulging locking portion 27e of the retaining member 27 abuts on the periphery of the locking hole 14a, the bulging locking portion 27e does not suddenly have a large diameter, and the bulging locking portion 27e and the shaft portion 27d bulge. Since the bulging engagement portion 27e does not suddenly have a large diameter such that stress concentration is likely to occur at a boundary portion with the portion 27e, there is no possibility that the bulging engagement portion 27e is damaged, and
The cap 25 can be prevented from coming off the garnish body 12.

In the cap 25 of the embodiment, a locking hole 26d is provided in the mounting portion 26c on the lid main body 26 side, and a locking hole 26d on the periphery of the locking hole 26d is provided in the mounting locking portion 27a on the retaining member 27 side.

It may be configured to provide 66d. Note that, like the cap 25, the cap body 66
An outer skin 66f is attached to the outer surface side of the molded portion 66a, and a locking claw 66b that can be locked in a locking groove 29b of a head 29a of the mounting bolt 29 is provided. At the tip of a shaft portion 67d extending from the assembly locking portion 67a, a bulging locking portion 67e having a tapered large diameter from the shaft portion 67d and having a larger outer diameter than the locking hole 14a of the garnish body 12 is provided. Have.

Also, as shown in FIGS. 17 and 18, as shown in FIG.
The undercut stop with the assembling locking portion 77a may be performed using heat caulking. That is, a locking hole 76c is provided in the assembly portion 76b of the lid body 76, and the retaining member 7
7 is provided with a rod-shaped portion 77b which can be inserted into the locking hole 76c, and the rod-shaped portion 77b is inserted into the locking hole 76c.
c, the tip is heated and softened so that the locking hole 76
By providing a flange portion 77c which is undercut-stopped on the locking surface 76d of the peripheral edge of c, the mounting locking portion 77a of the retaining member 77 may be mounted and locked to the mounting portion 76b of the lid body 76. .
