Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a webbing guide device used in a seat belt device for protecting an automobile occupant and for guiding an occupant restraining webbing.

Conventional devices of this type include, for example, the first and second
There is one shown in the figure. That is, a center pillar lower trim B and a center pillar upper trim A, which are divided into upper and lower halves, are attached to the center pillar S, and a retractor 2 is disposed inside the center pillar lower trim B, and one end is attached to the retractor 2. The connected webbing 1 connects to the edge of center pillar lower trim B and center pillar upper trim A.
It is guided into the vehicle interior through an opening _H1 provided on the center pillar lower trim B side at the joint with the edge of the center pillar lower trim B. Then, a fixing device C, which is a webbing guide for reversing the webbing 1 to the guide side, is attached to the upper side of the back surface of the center pillar lower trim B.
The center pillar lower trim B is secured to the center pillar S by the clip C ₁ of this fixture C, and the fixture C is connected to the opening H ₂ of the webbing 1.
It has a configuration in which it forms a webbing guide and also serves as a webbing guide. In addition, U in the figure is a bracket formed integrally with the center pillar lower trim B, and is formed so that the claw _C2 of the fixture C can be inserted and locked into this bracket U. However, in the conventional example with the above configuration, when installing the fixture C, it must be placed inside the center pillar lower trim B, which makes the installation work inefficient. Also, the fixture C itself has a locking piece C ₁ on the center pillar S.
, and the claw C ₂ is the center pillar lower trim B
There is such a complexity that it has to be engaged with the bracket U of.

In response to such complexity, there are conventional examples shown in FIGS. 3 and 4. (Refer to Utility Model Application No. 56-14755.) This conventional example differs from the previous example in that the fixture C, which is a webbing guide, is attached to the upper end of the center pillar lower trim _B1 by a clip _C4 .
Although the structure is simpler than that of the known example, it must have exactly the same structure as the known example in that the fixture C itself must be attached or manufactured separately. . In addition, when specifically installing the fixture C, in any case, it may be engaged with the mounting hole of the center pillar S or through the edge of the center pillar lower trim B. A means is required, and therefore, when repeatedly attaching and detaching, the engaging portion of the member itself is likely to be damaged, and there is a problem that so-called rattling may occur in the case of an incorrect attachment operation.

This invention was made by focusing on such conventional problems, and avoids all the above-mentioned inconveniences caused by separately providing a conventional webbing guide, and replaces the conventional webbing guide. By forming a first guide part and a second guide part on each end edge of the first trim and the second trim so as to be provided directly on the trim, and forming an opening for the webbing with the first guide part and the second guide part. , aims to solve the above problems.

The present invention will be explained below based on the drawings.

FIGS. 5 to 8 show an embodiment of the present invention.

First, to explain the configuration, S is the center pillar,
M is the center pillar upper trim which is the first divided trim, L is the center pillar lower trim which is the second trim, G ₁ is the first guide part formed at the edge of the center pillar upper trim M, and G ₂ is the center pillar upper trim. The second guide part formed in the notch D on the edge of the center pillar lower trim L, H is the opening of the seat belt webbing guide formed by the first guide part _G1 and the second guide part _G2 of the notch D. A feature of the present invention is that this opening H is formed by the first guide part _G1 and the second guide part _G2 . To explain in more detail, one end of the webbing 1 that is attached to the occupant is folded back by a through ring 3 before being wound around a retractor 2, and a pillar inner panel S that forms a center pillar S with a pillar outer panel S2 is folded back at one end by a through ring ₃ . ₁ , and the middle and lower parts need to be covered to avoid contact with passengers. Therefore, the center pillar lower trim L has a deep U-shaped cross section with a wall 4 on the passenger compartment side and side walls 5 and 6, and a concave notch D is provided in the upper flat part 7 through which the webbing 1 is inserted. It is formed to be able to cover the webbing 1. Furthermore, on the long side of this notch D, there is a second guide portion having a gently curved surface so as to properly bend the plane of the webbing 1 and guide it smoothly.
G ₂ is formed. Further, at both ends of the notch D, engaging pieces 8, 8 that engage with the inner corner portions of the center pillar upper rim M are formed to protrude.

On the other hand, the center pillar upper trim M has a shallow U-shaped cross section so as to cover the upper part of the pillar inner panel S ₁ , and the interior wall 9 forming the long side of the U-shape. A convex first guide portion _G1 protruding toward the vehicle interior is provided at the lower portion. Further, the end of the convex portion forming the first guide portion _G1 is extended downward to form a flat portion 10, and a mounting screw 11 is screwed into this flat portion 10 into a mounting hole provided in the pillar inner panel _S1 . Screw hole 1 to insert
2 is provided.

The above center pillar upper trim M and center pillar lower trim L are attached to the pillar inner panel.
To install it on S ₁ , first place the center pillar upper trim M so as to cover the upper part of the pillar inner panel S ₁ , and insert the mounting screw 11 inserted into the screw hole 12 into the mounting hole of the pillar inner panel S ₁ . 2
Screw it to 0. As a result, the center pillar upper rim M is mounted in contact with the side surface of the welt W that clamps the flanges 13, 14 of the pillar inner panel _S1 and the pillar outer panel _S2 . Next, the webbing 1 is inserted into the concave notch D on the upper part of the center pillar lower trim L, and the engaging pieces 8, 8 provided at the ends of the notch D are inserted.
Insert from below the center pillar upper trim M installed above. As a result, the center pillar lower trim L is also indirectly attached to the side surface of the welt W, similarly to the center pillar upper trim M. By installing both trims M and L, as shown in _FIG . The guide portion _G2 faces each other, and an opening H for guiding the webbing is formed. The above-mentioned installation work is all visual confirmation work, so it can be easily performed without any mistakes.

The webbing guide opening H configured as described above is formed with an appropriate curved surface so that the width P is the minimum required (that is, about several times the thickness of the webbing 1) in the middle in the vertical direction, Webbing 1
The middle part of the webbing 1 is appropriately bent to guide the webbing 1 along the curved surface of the pillar inner panel S ₁ , and also to prevent the inconvenience of the webbing 1 from twisting when it is forcefully taken up by the retractor 2. It acts like this.

9 to 11 show other embodiments of the invention.

In this embodiment, flanges 15 and 16 are formed on both the center pillar trims M and L, which are the first and second trims divided into two, respectively, and the engaging piece 8 of the center pillar lower trim L in the above-described embodiment is It is provided with a mounting function corresponding to the flat part 10 provided with the screw hole 12 of the center pillar upper rim M. That is, in this case, to attach both trims M and L to _the pillar inner panel _S1 , as shown in _FIG . This is done by holding the flange 14 together with the welt W, and therefore the center pillar lower trim L is directly attached without going through the center pillar upper trim M.

By installing both trims M and L, a first guide part _G1 provided at the lower edge of the center pillar upper trim M and a second guide part _G2 provided at the upper edge of the center pillar lower trim L are formed. are opposite to each other and the opening H for guiding the webbing is formed in the first
This is the same as in the embodiment.

Note that the second hole formed on the long side of the notch D of the center pillar lower trim L in the embodiment of this invention
The shape of the guide portion _G2 may be a rib shape as shown in FIG. In addition, although an example has been shown in which the guide opening H is formed by a combination of concave and convex portions consisting of a concave notch D and a convex guide surface _G2 , the present invention is not limited to this. It is also possible to consider a combination of one trim having a flat surface and the other trim having a notched concave shape.

As described above, according to the present invention, the structure of the webbing guide device is such that the first guide portion is provided at the lower edge of the center pillar upper trim, and the first guide portion is provided at the upper edge of the center pillar lower trim that covers the webbing. 2 guide parts are provided, and the center pillar upper trim is attached above the center pillar, and the center pillar lower trim is attached below the center pillar either directly or indirectly via the center pillar upper trim. Since the first and second guide parts are made to face each other to form an opening, which is extremely simple, all the inconveniences associated with providing a separate fixing device with an opening for guiding the webbing can be avoided. Therefore, it is easy to manufacture, the number of man-hours for installation is reduced, and work efficiency is good, and it is suitable for low-cost mass production, and there is no damage to the members, making it possible to use it repeatedly.
