DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outlet structure for a vehicle seat belt.

[0002]

2. Description of the Related Art FIG. 8 shows an example of a conventional seat belt pull-out structure for a vehicle (see Japanese Utility Model Laid-Open No. 57-37053 as a similar technique).

[0003] Reference numeral 1 denotes a right side rear panel (vehicle body) of an automobile, and a side trim 2 is provided inside the side panel 1. A retractor (ELR) 3 that can take up and pull out the webbing W is fixed to a side panel 1 inside the side trim 2.

An outlet 4 is formed in the upper surface 2a of the side trim 2, and an escutcheon 6 in which a webbing W insertion opening 5 is formed is attached to the outlet 4.

Then, the webbing W in the retractor 3
Is drawn out of the side trim 2 through the outlet 4 and the insertion opening 5, passes through the through ring 7 provided at the upper part of the side panel 1, and then passes through the inlet 8 at the lower end of the side trim 2. Is fixed to an anchor 10 set on a floor panel (vehicle body) 9. Note that a tongue 11 is passed through the webbing W in the middle.

On the other hand, a rear seat 12 is installed at a position adjacent to the side trim 2. An outlet 13 is formed near the center of the seat cushion 12 a of the rear seat 12, and a fixed belt 15 having a lower end connected to an anchor 14 below the rear seat 12 is drawn out from the outlet 13. A buckle 16 is attached to the tip of the fixed belt 15. The tongue 11 of the webbing W pulled out is inserted into and engaged with the buckle 16, so that the occupant on the rear seat 12 can be restrained by three-point support.

[0007]

However, in such a conventional technique, the webbing W is drawn out to the vehicle interior through the outlet 4 of the side trim 2 and the insertion port 5 of the escutcheon 6. Therefore, as a mounting procedure of the webbing W, first, the webbing W pulled out from the retractor 3 is temporarily inserted into the outlet 4 of the side trim 2, the insertion port 5 of the escutcheon 6, and the through ring 7 before mounting. Leave them in each state,
Then, attach the retractor 3, the through ring 7, and the anchor 10 to the side panel 1 and the floor panel 9, respectively.
Finally, the side trim 2 is attached to the side panel 1, but this series of operations is very difficult. In other words, even though the relatively small size of the escutcheon 6 and the through ring 7 is passed through the webbing W, the workability is not so disadvantageous, but the webbing W is passed through the outlet 4 of the large side trim 2. In the state
To perform the mounting of the retractor 3 and the like, the worker must support the side trim 2 with a part of the body or one hand not working while performing the mounting operation of the retractor 3 or the like. You will have to work very hard. Therefore, a proposal for a structure that allows the side trim 2 to be retrofitted separately from the seat belt W is desired.

In addition, the escutcheon 6 must be firmly positioned after mounting, and it is necessary to provide some positioning means between the escutcheon 6 and the outlet 4.

The present invention has been made by paying attention to such a conventional technique, and has a draw-out structure for a vehicle seatbelt in which a side trim can be retrofitted and an escutcheon can be reliably positioned with respect to the draw-out. To provide.

[0010]

In order to achieve the above object, a seat belt withdrawal structure according to the present invention has a rectangular shape extending in the front-rear direction for drawing webbing from a retractor inside a side trim into a vehicle interior. Is formed on the upper surface of the side trim and a rear portion of the outlet is formed.
Form a slit for webbing introduction at the outer corner with
Further, an escutcheon having a webbing insertion port is attached to the outlet, and a covering portion that covers the front side of the slit is formed at a rear portion of the escutcheon, and the covering portion is drawn out to the back surface of the covering portion.
A holding piece that is inserted from the inside of the mouth and supports the slit peripheral part from the back side , and between the covering part and the holding piece.
A center rib to be inserted into the slit is formed at
A claw that can be engaged with the inner edge of the outlet
Part and the contact part that contacts the outer edge of the outlet
A claw portion formed at the same time as engaging the inner edge portion, and an outer edge portion
The abutting parts that abut against the inner and outer edges
Formed at a substantially central position in FIG. here,
"Side trim" is a broad concept including pillar garnish and the like.

[0011]

According to the present invention, the retractor, the through ring, the anchor and the like are fixed to the vehicle body with only the small escutcheon and the through ring being passed through the webbing, and the webbing side is attached separately from the side trim. To finish. Next, the side trim is attached to the vehicle body. At this time, since the slit for introducing the webbing is formed in the outlet of the side trim, the webbing can be introduced into the outlet using the slit and can be retrofitted to the vehicle body of the side trim.

Further, since the escutcheon is formed with a covering portion that covers the front side of the slit, the slit portion is not exposed to lower the appearance, and the occupant's clothes and the like do not catch on the slit portion. . Further, a holding piece for supporting the slit peripheral portion from the back side is formed on the covering portion, and since the slit peripheral portion is fixed by the holding piece, rattling of the slit portion can be reliably prevented.

Furthermore, on the back of the escutcheon,
Since the claw portion and the abutting portion with respect to the edge are formed downward, once mounted, the escutcheon does not shift with respect to the outlet. In particular, the claws and abutments corresponding to the inner and outer edges of the outlet are
Since it is formed at a substantially central position in the front-rear direction of the portion, it is possible to prevent the front end of the escutcheon from being displaced in the left-right direction after mounting and to improve the workability of mounting the escutcheon.

That is, if only the position of the front end of the escutcheon is prevented from shifting in the left-right direction, the claw portions and the contact portions corresponding to the inner edge portion and the outer edge portion of the escutcheon are required.
Order may be set in the front position, Then the front end of the escutcheon around the rear part of the clamping piece in the process to be pivoted downward, the claw portions provided on the front side and the abutment portion out of the
The timing of contact (engagement) with the edge is delayed, making it difficult to securely attach the escutcheon. In other words, you must turn the front end of the escutcheon down to the end.
Since the positional relationship is not known, if the position is misaligned, it must be reinstalled, which is very disadvantageous in terms of workability.

On the other hand, in the present invention, the inside and outside of the outlet are provided.
Both the claw and the abutment are in the front-back direction of the corresponding edge
The claw portion and the contact portion abut (engage) with the corresponding edge portion of the outlet during the downward rotation of the escutche around the holding piece. At that point, the attitude of the escutcheon in the left-right direction with respect to the outlet is corrected, so if the escutcheon is turned downward as it is,
Good. Moreover, thus, it is formed in a substantially central position in the longitudinal direction of the edge which the claw portion and the contact portion corresponds both, without providing the claw portion and the contact portion on the front side,
Deflection (displacement) in the left-right direction of the front end of the escutcheon centering on the rear holding piece is almost certainly prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described with reference to FIGS.
It will be described based on. In addition, the same reference numerals are given to portions common to the related art, and overlapping description will be omitted.

The outlet 18 of the side trim 17 according to this embodiment has a rectangular shape extending in the front and rear directions.
Is formed with a slit 19 at the corner of . On the other hand, the escutcheon 20 attached to the outlet 18 has a size that covers the periphery of the outlet 18, and the slit 19 is also covered by a covering portion 21 corresponding to the slit 19, It is not exposed inside the car.

On the back side of the escutcheon 20, four front and rear edges 18a, 18b, 1
Claw portions 22a, 22c respectively corresponding to 8c, 18d
And the large and small contact portions 25b and 25d are formed downward. That is, a claw portion 22a is formed on the front side, which can be engaged with the front edge portion 18a of the outlet port 18, and a small U-shaped contact portion 2 which is in contact with the rear edge portion 18b is provided at a slightly left position on the rear side.
5b are formed. Also, the front-back direction of the inner edge portion 18c
At the position corresponding to the approximate center (slightly from the front side)
Claw portion 22c which engages with the inner edge 18c is formed, the outer edge portion substantially central large abutment portion 25d of the abutting U-shaped section to the inner edge 18d is in a position corresponding to the (slightly from front side) in the longitudinal direction of 18d Are formed. In this way before and after
In the inward and outward directions, the portions farther from the holding piece 24 to be described later are the claw portions 22a and 22c, and the closer portions are the contact portions 25b and 25d, so that the escutcheon 20 is prevented from rising and is securely mounted. At the end of the insertion hole 26 of the escutcheon 20, flanges 27 bent rearward are provided.

The covering portion 21 of the escutcheon 20
The holding piece 24 is formed on the back surface 21a of the holding member.
That is, the holding piece 24 has a base 24 a at a position on the back surface 21 a of the covering portion 21 corresponding to the slit 19 and in the outlet 18.
It has a substantially L-shaped cross section formed outwardly along 9. An interval S corresponding to the thickness of the upper surface portion 17a of the side trim 17 is provided between the portion 24b of the holding piece 24 on the side of the base 24a and the back surface 21a of the covering portion 21. 24 has a rear surface 21a.
It is in a state inclined in a direction away from the camera. A center rib 28 that slightly engages with the slit 19 is provided between a portion 24b of the holding piece 24 on the side of the base 24a and the covering portion 21. The distal end side of the center rib 28 is also inclined like the distal end portion 24c of the holding piece 24. Further, side ribs 29 formed toward the back side are formed at both ends of the holding piece 24. The side rib 29 also extends from the base 24a of the holding piece 24 to the back surface 21a between the flanges 27 of the insertion opening 26.

The width E of the holding piece 24 is
It extends from near the starting point of 9 to the tip 24c,
The width E is a width capable of supporting most of the peripheral portion of the slit 19 covered by the covering portion 21 from below. Therefore, even if a downward force is applied to the peripheral portion of the slit 19 by pressing the upper surface portion 17a or the escutcheon 20 portion of the side trim 17 with the occupant's hand or luggage, the holding portion 24 having the wide width E is covered. In part 21
Since the periphery of the slit 19 is securely held, the periphery of the slit 19 does not come off the holding piece 24.

Next, the mounting procedure will be described. In this embodiment, since the slit 19 is provided, it is not necessary to pass the webbing W through the outlet 18 of the side trim 17 in advance.
And then retrofitted to the side trim 17.

Attachment of webbing: With only the small escutcheon 20 and the through ring 7 passed through the webbing W, the retractor 3, the through ring 7, and the anchor 10 are attached.
Are fixed to predetermined side panel 1 and floor panel 9, respectively. Thus, the mounting operation on the webbing W side is completed.

Attachment of side trim: Next, the side trim 17 is attached. First, the tongue 11 is pulled to draw out the webbing W to the passenger compartment side. The side trim 17 is inserted between the webbing W up to the retractor 3 and temporarily set. Next, the through ring 7
The webbing W from the part up to the retractor 3 is introduced into the outlet 18 through the slit 19. After passing the webbing W through the outlet 18 in this manner, the side trim 17 is finally fixed to the side panel 1.

Attachment of escutcheon (see FIG. 7): Finally, escutcheon 20 is attached to outlet 18. The attachment of the escutcheon 20 to the outlet 18
First, as shown in FIG. 7, and the escutcheon 20 obliquely, plug so as to insert the holding pieces 24 in its rear to the back side of the slit 19, at the same time a U-shaped abutment
The portion 25b is applied to the trailing edge 18b of the outlet 18. At the time of inserting the holding piece 24, the distal end 24 c of the holding piece 24
The work is easy because the is in an inclined state.

In this manner, the holding piece 24 is
9, the contact portion 25b is brought into contact with the rear edge portion 18b, and then the front end of the escutcheon 20 is rotated downward about the rear holding piece 24 and the contact portion 25b. As soon as the escutcheon 20 is pivoted down,
The claw portion 22c and the contact portion 25d, which are provided at positions substantially corresponding to the center in the front-rear direction of the inner and outer edges 18c, 18d,
The escutcheon 20 enters the inside of the corresponding edge portions 18c and 18d and corrects the attitude of the escutcheon 20 with respect to the outlet 18 in the left-right direction. That is, the escutcheon 20 is straightened along the outlet 18. Therefore, if pushed as it is rotated downward to the front end of the escutcheon 20, the left and right claw portions 22c and the abutment portion 25d is more reliably and out
Engages (contacts) the left and right edges 18c, 18d of the
The claw portion 22a at the front end of the escutcheon 20 is positioned at the front edge portion 18a.
Will be securely engaged. Thus, the attachment of the escutcheon 20 is completed. On the other hand, as shown by phantom lines in FIG. 7, when the claw portions 22c and the like corresponding to the inner and outer edges 18c and 18d are set on the front side as virtual claw portions K1 and the like, the tip of the front claw portion 22a is set. Since the virtual claw portion K1 does not enter the outlet 18 until the escutcheon 20 rotates downward, the posture of the escutcheon 20 with respect to the outlet 18 is not reached until the escutcheon 20 reaches the front edge 18a of the outlet 18. May not be corrected, and in some cases, the claw portion 22a at the front end may be inclined with respect to the front edge portion 18a, and a situation may occur in which the front claw portion 22a is not securely engaged with the front edge portion 18a.

Then, the escutcheon 20 once attached to the outlet 18 is inserted into the insertion port 26.
Even if a load is applied from the inside webbing W, the movement to the front side is regulated by the claw portion 22a hitting the front edge portion 18a, and the movement to the rear side is caused by the contact portion 25b contacting the rear edge portion 18b. Be regulated. And the rear holding piece 24
The swing of the front end of the escutcheon 20 around the center rib 28 (specifically, the center rib 28) (the C and D directions in the figure) is as follows.
The claw portion 22c and the contact portion 25d are regulated by contacting the corresponding inner and outer edges 18c and 18d, respectively. In this manner, the movement of the front end of the escutcheon 20 in the left-right direction (the C and D directions in the figure) can be restricted because both the claw portion 22c and the contact portion 25d have the inner and outer edge portions 18c, 1c.
8d is because positioned at substantially the center in the longitudinal direction of, for example, as an abutment K2 virtual outer contact portion 25d, the tentatively set on the rear side of the right edge 18 d, the right front end of the escutcheon 20 The displacement in the direction (D direction) cannot be regulated.

In addition, in this embodiment, when the escutcheon 20 is mounted, the slit 19 of the side trim 17 is covered by the covering portion 21 of the escutcheon 20, so that the slit 19 is directed toward the vehicle interior. The appearance is not deteriorated by being exposed, and the clothes and the like of the occupant do not get caught on the slit 19 portion. Further, since the peripheral portion of the slit 19 is supported from the back side by the holding piece 24, both sides of the slit 19 are sandwiched between the covering portion 21 and the holding piece 24, and this portion is rattled. Prevention is ensured.

[0028]

The seat belt pull-out structure according to the present invention has the contents as described above, and can be attached to the side trim separately from the webbing later. Workability is greatly improved.

Also, the inner and outer claws and the abutting portion of the outlet are the same.
It is formed at a substantially central position in the front-rear direction of the corresponding edge portion, and the two claws and the abutting portion enter the inside of the outlet while attaching the escutcheon to the outlet,
Since the attitude of the escutcheon with respect to the outlet is corrected, the mounting of the escutcheon with respect to the outlet can be performed without failure. Therefore, the workability of attaching the escutcheon is improved.

Furthermore, the fact that the inner and outer claws and the abutting portion of the outlet are formed substantially at the center of the corresponding edge in the front-rear direction means that the rear holding piece is centered. Therefore, it is possible to reliably prevent the front portion of the escutcheon from being displaced in the left-right direction, and to reliably position the escutcheon with respect to the outlet after the attachment.

In addition, since the escutcheon is formed with a covering portion that covers the front side of the slit, the slit portion is not exposed to lower the appearance, and the occupant's clothes and the like are not caught by the slit portion. Absent. Further, a holding piece for supporting the slit peripheral portion from the back side is formed on the covering portion, and since the slit peripheral portion is fixed by the holding piece, rattling of the slit portion can be reliably prevented.
