Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a webbing cover holder that is attached to an end of a webbing cover that covers the webbing for a seat belt device and locks the webbing cover to the webbing.

[Prior Art] Conventionally, in a seat belt device that restrains an occupant with webbing in a vehicle emergency, a middle portion of the webbing, particularly a shoulder webbing portion that restrains the upper body of the occupant, is used to prevent direct sliding contact between the occupant and the webbing. The idea was to cover it with a cylindrical webbing cover.

Conventionally conceived webbing covers are generally formed into a cylindrical shape with a button or the like interposed therebetween, so that they can be easily attached and detached from the webbing when washing. In addition, when installing the webbing cover, a holder is attached to the upper end of the webbing cover, and the upper end of the webbing cover is locked to the webbing or the vehicle body via the holder to prevent the webbing cover from slipping down. It is common to be familiar.

For example, in the webbing cover 10 shown in FIG. 12, both ends in the width direction are joined via buttons 12 to form a cylindrical shape, and the upper end has a holder 1.
4 is installed. To attach the holder 14 to the webbing cover 10, attach the joint connecting part of the webbing cover 10 to the spaced part 14A of the holder 14.
An engagement groove 14 formed along the circumferential direction of the holder 14 so that the upper end of the webbing cover 10 matches the
This is done by fitting into B. Holder 14
In the attached state, as shown in FIG. 13, the thick rigid part 18, which is sewn by bending the upper end of the webbing cover 10 with the film 16 in between, is locked to the holder 14, and the holder 14 and the webbing cover are held together. 10 are reliably connected.

When attaching the webbing cover 10 to the webbing 20, remove the button 12 and attach the holder 14.
An opening that communicates with the spacing portion 14A may be formed along the longitudinal direction of the webbing cover, and after passing the webbing 20 through this opening, the webbing cover 10 may be formed into a cylindrical shape using the button 12. When attached to the webbing 20, the tip of the locking portion 14C as a locking protrusion of the holder 14 comes into frictional contact with the webbing 20, thereby causing the webbing cover 1 to
0 is secured to the webbing 20 through the holder 14 to prevent it from slipping down.

By the way, the holder 14 and the webbing cover 10
In order to reliably connect the two, it is necessary to connect the engagement groove 14B of the holder 14 to the thick rigid part 1 of the webbing cover 10.
Conventionally, the circumferential length of the separating part 14A of the holder 14 is set longer than the circumferential length of the joint part of the webbing cover 10, and the separating part 14A is It has been considered to make the engagement groove 14B of the holder 14 narrower by providing a relief at the joint portion of the webbing cover 10.

However, as mentioned above, the webbing cover 10
If only the spaced apart part 14A of the holder 14 is provided with a joint relief, the holder 14 will be attached to the webbing cover 10 only at the position where the spaced part 14A coincides with the joined part of the webbing cover 10, and the webbing cover 10 The mounting position was constant.
On the other hand, in the seat belt device, webbing 20
However, the slip joint 1 is pivotally supported on the side wall of the car body.
9 (shown in FIGS. 14 to 17) to form a shoulder webbing portion that restrains the upper body of the occupant. In this case, there are the following types. The first type is a type in which the webbing 20 is twisted after passing through the slip joint 19, that is, the upper part of the shoulder webbing part is twisted, as shown in FIGS. 14 and 15.
As shown in FIGS. 16 and 17, this is a type in which the webbing 20 is not twisted after passing through the slip joint 19, that is, the upper part of the shoulder webbing is not twisted. The twisting type is mainly used when the slip joint 19 is located behind the passenger, such as in a two-door car, while the non-twisting type is mainly used in a four-door car. The slip joint 19 is used when the slip joint 19 is located near the side of the passenger, and by using the slip joint 19 properly in this way, the shoulder webbing portion can be appropriately fitted to the passenger.

In addition, the webbing 20 is shown in FIGS. 13 to 17.
As shown in the figure, the webbing 20 is folded back and bent at the slip joint 19, and the locking part 14c of the holder 14 is connected to the surface of the webbing 20 opposite to the folded side (as shown in FIGS. 14 and 15). In the type where the upper part of the shoulder webbing part is twisted, this is the contact surface of the webbing 20 with the passenger, and the first
In the type shown in Figures 6 and 17 in which the upper part of the shoulder webbing part is not twisted, the webbing 20
This is the surface opposite to the surface in contact with the passenger. ) and is configured to be locked to the surface, and when the webbing is attached, the locking part 14c is located at the webbing 2.
0 to prevent the webbing cover 10 from slipping down, but when the webbing is retracted after the webbing is released, the webbing cover 10 moves as the webbing is retracted and the webbing cover 10 moves to the locking portion 1.
4c comes close to the slip joint 19, the webbing 20 bends to release the locking portion 14c.
The webbing cover 10 separates from the webbing 20 and is no longer locked to the webbing 20, so that the webbing cover 10 does not follow the subsequent winding of the webbing 20, and the winding continues smoothly.

Therefore, the webbing cover 1 is appropriately attached to a type in which the webbing 20 is twisted, and the connecting portion of the webbing cover 10 faces the passenger side.
0 is attached to a type in which the webbing 20 cannot be twisted, when the connecting part of the webbing cover 10 faces the passenger side, the position of the locking part 14c is located on the folded side surface of the webbing 20. This will cause some inconvenience. In order to avoid this, the connecting portion of the webbing cover 10 must be directed toward the side opposite to the passenger side. However, it may be considered undesirable to direct the connecting portion of the webbing cover 10 toward the side opposite to the passenger side because the connecting portion is exposed, from the perspective of viewing.

Of course, there is no problem in directing the connecting part of the webbing cover 10 to the side opposite to the passenger rather than toward the passenger, except for the point of view.On the contrary, depending on one's hobbies, etc. There may also be cases where it is desired that the connecting portion of the vehicle be directed toward the side opposite to the passenger rather than toward the passenger. However, for example,
Regarding the webbing cover 10 that is attached with the connecting part of the webbing cover 10 facing the passenger side, even if the connecting part is desired to face the side opposite to the passenger, it is not possible to connect the connecting part to the side opposite to the folded side of the webbing 20. This was not possible due to the need to position the stop portion 14c.

Therefore, it was not possible to change the mounting direction of the webbing cover 10 (the direction of the joint relative to the occupant).

[Problems to be solved by the invention] In consideration of the above facts, the present invention securely maintains the holding of the webbing cover by escaping the connection part of the webbing cover, and also maintains the locking protrusion on the same side of the webbing. For example, regardless of the direction in which the webbing cover is attached, the locking protrusion is always located on the side opposite to the folded side of the webbing at the slip joint, making it possible to attach the webbing cover. in some cases,
Although the locking protrusion locks the webbing and prevents the webbing cover from slipping down, when the webbing is retracted after the webbing is released, the locking protrusion separates from the webbing at the slip joint and prevents the webbing cover from slipping off. The purpose is to release the webbing cover so that the webbing cover does not follow the winding of the webbing so that the winding can be smoothly performed.

[Means for solving the problems] The webbing cover holder according to the present invention has the following features:
This is a webbing cover holder that is attached to the longitudinal end of the webbing cover, which is formed into a cylindrical shape by connecting both side edges along the longitudinal direction of the webbing to each other. A cylindrical part that maintains its shape in a flat cylindrical shape and is engaged with the end of the webbing cover, and a cylindrical part that is provided on the cylindrical part and is located on one side of the webbing to lock that one side and slide the webbing cover. A locking protrusion that prevents the webbing cover from falling, a first escape part that is a space provided on one wide side of the cylindrical part and in which the webbing cover connecting part is located, and a first relief part that is provided on the other wide side of the cylindrical part. A second escape part is a space in which the webbing cover connecting part is located.

[Function] In the webbing cover holder configured as described above, the cylindrical portion is engaged with the end portion of the webbing cover, thereby being reliably connected to the webbing cover. When the cylindrical part and the end of the webbing cover are engaged, the webbing cover connecting part is located at one of the first and second relief parts of the cylindrical part.

When the webbing cover connecting part is located at the first relief part of the cylindrical part and when the webbing cover connecting part is located at the second relief part of the cylindrical part, the webbing relative to the cylindrical part The direction of the cover connection part is different.

Therefore, the cylindrical part and the end of the webbing cover can be engaged with each other even if the direction of the connecting part of the webbing cover with respect to the cylindrical part is changed. Therefore,
Even if the position of the cylindrical part with respect to the webbing cover changes, the connecting part of the webbing cover escapes to the first relief part or the second relief part, so that the webbing cover is reliably maintained, and the locking protrusion Since the position of the locking projection changes with respect to the webbing cover together with the cylindrical portion, the position of the locking protrusion is maintained on the same side of the webbing regardless of the mounting direction of the webbing cover. As a result, for example, regardless of changes in the mounting direction of the webbing cover, the locking protrusion is always located on the surface of the slip joint opposite to the folded side of the webbing, and when the webbing is attached, the locking protrusion locks the webbing. This prevents the webbing cover from slipping down, but when the webbing is taken up after the webbing is released, the locking protrusion separates from the webbing at the slip joint and the webbing is released, preventing the webbing from being taken up. Winding is performed smoothly without the webbing cover following the movement.

That is, even if the position of the short cylindrical body 50 with respect to the webbing cover 40 changes, the connecting part of the webbing cover 40 escapes to the spaced part 54 or the notch 56 of the auxiliary member 66, so that the webbing cover 40 is reliably maintained. , and the locking protrusion 52 is connected to the short cylindrical body 50.
At the same time, by changing the position with respect to the webbing cover 40, the position of the locking protrusion 52 is maintained on the same side of the webbing regardless of the mounting direction of the webbing cover 40. As a result, regardless of the change in the mounting direction of the webbing cover 40, the locking protrusion 5
2 is always located on the opposite side of the folded side of the webbing 22 in the slip joint 30, and when the webbing is attached, the locking protrusion 52 locks the webbing 22 to prevent the webbing cover 40 from slipping down. However, when the webbing is wound up after the webbing is released, the locking protrusion 52 at the slip joint 30 separates from the webbing 22 and is no longer locked with the webbing 22, so that the webbing cover 40 does not follow the winding of the webbing 22. Winding is performed smoothly. In this embodiment, the webbing cover 4 is used in a seat belt device of a type in which the webbing 22 is not twisted at the slip joint 30, that is, the upper part of the shoulder webbing is not twisted.
0 has been described, the webbing 22 is twisted at the slip joint 30, that is, the upper part of the shoulder webbing is twisted. The same applies to the case where the webbing cover 40 is changed, or when the webbing cover 40 is replaced between a type in which the upper part of the shoulder webbing is not twisted and a type in which the upper part of the shoulder webbing is twisted. However, the locking protrusion 52 must always be located on the surface of the slip joint 30 opposite to the folded side of the webbing 22.
