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. Additionally, 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 via the holder to prevent the webbing cover from slipping down. It is common for there to be.

For example, webbing cover 1 shown in FIG.
0, both ends in the width direction are joined via buttons 12 to form a cylindrical shape, and a holder 14 is attached to the upper end.
is installed. The attachment of the holder 14 to the webbing cover 10 is performed by attaching the holder 14 to the webbing cover 10.
The upper end of the webbing cover 10 is attached to the holder 14 by aligning the joint part 0 with the separating part 14A of the holder 14.
This is done by fitting into an engagement groove 14B formed along the circumferential direction of the holder. In the attached state of the holder 14, as shown in FIG. and webbing cover 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. 9 to 12) to form a shoulder webbing portion that restrains the upper body of the occupant. In this case, there are the following two types. First, as shown in FIGS. 9 and 10, the webbing 20 has a slip joint 19.
This type is twisted after passing through the shoulder webbing, that is, the upper part of the shoulder webbing is twisted.
As shown in FIGS. 11 and 12, 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.

Further, as shown in FIGS. 7 to 12, the webbing 20 is folded back and bent at the slip joint 19, and the locking portion 14c of the holder 14 is located on the side opposite to the folded side of the webbing 20. (For the type in which the upper part of the shoulder webbing shown in FIGS. 9 and 10 is twisted, this is the contact surface of the webbing 20 with the passenger, and the upper part of the shoulder webbing shown in FIGS. 11 and 12 In the non-twistable type, the webbing 20 is located on the opposite side of the contact surface with the occupant. 20 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 prevent the webbing cover 10 from slipping down.
When comes near slip joint 19,
As the webbing 20 bends, the locking portion 14c 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. It is becoming more and more common.

Therefore, the webbing cover 1 is appropriately attached to a type in which the webbing 20 is twisted, and the joint part of the webbing cover 10 faces the passenger side.
0 is attached to a type in which the webbing 20 cannot be twisted, and when the joint 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 joint portion of the webbing cover 10 must face the side opposite to the passenger side. However, it is sometimes considered undesirable to have the joint of the webbing cover 10 facing the side opposite to the passenger side because the joint is exposed.

Of course, there is no problem in pointing the joint of the webbing cover 10 toward the side opposite to the passenger rather than toward the passenger, except for the point of view.On the contrary, depending on your hobbies, you may There may also be a case where it is desired that the joint 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 joint part of the webbing cover 10 facing the passenger side, even if it is desired to have the joint part facing away from the passenger, it is not possible to connect the webbing cover 10 to the surface 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] Taking the above facts into consideration, the present invention securely maintains the holding of the webbing cover by escaping the joint of the webbing cover, and also positions the locking protrusion on the same side of the webbing. For example, regardless of the change 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. When the webbing is attached, the locking protrusion locks the webbing to prevent the webbing cover from slipping down, but 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 from slipping off. The object of the present invention is to release the locking of the webbing, and to enable smooth winding of the webbing without the webbing cover following the winding of the webbing.

[Means for solving the problems] The webbing cover holder according to the present invention has the following features:
A holder for a webbing cover that is attached to a longitudinal end of a webbing cover whose both side edges along the longitudinal direction of the webbing are connected to each other to form a cylindrical shape, the holder having a cylindrical part formed in a flat cylindrical shape; A locking protrusion is provided on the cylindrical part and is located on one side of the webbing to lock the one side to prevent the webbing cover from slipping down, and a locking protrusion is formed in a flat cylindrical shape corresponding to the cylindrical part. A housing groove is provided that can be engaged with the cylindrical part at two positions where the wide surface coincides with the wide surface of the cylindrical part, and that can accommodate and hold the end of the webbing cover with the cylindrical part. and an auxiliary member having a spacing section formed on a wide surface to separate the accommodation groove and allow the joint of the webbing cover to escape.

[Function] In the webbing cover holder configured as described above, the cylindrical portion is engaged with the auxiliary member to form a housing groove, and the end portion of the webbing cover is housed and held in the housing groove and attached to the webbing cover.

When the cylindrical portion and the auxiliary member are in an engaged state, their relative positions are one of two positions where the wide surface of the auxiliary member matches the wide surface of the cylindrical portion.

If you change the relative position of the cylindrical part and the auxiliary member and engage them without changing the relative position of the webbing cover and the auxiliary member, that is, the other one that can engage the cylindrical part and the auxiliary member When engaged in position, the relative position of the cylindrical part and the webbing cover is changed, and the orientation of the webbing cover joint with respect to the cylindrical part is changed. Therefore, even if the mounting direction of the webbing cover is changed, the relative position between the webbing cover and the auxiliary member does not change, and the joint part of the webbing cover escapes to the spaced part of the auxiliary member, and the retention of the webbing cover is reliably maintained. The position of the locking projection relative to the webbing cover changes together with the cylindrical portion, and the position of the locking projection is maintained on the same side of the webbing. 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.

[Effects of the invention] As explained above, the webbing cover holder according to the invention has a flat cylindrical shape and a cylindrical part provided on one side of the webbing. A locking protrusion that locks on one side to prevent the webbing cover from slipping down, and a flat cylindrical shape that corresponds to the cylindrical part, and a cylindrical shape at two positions where the wide side matches the wide side of the cylindrical part. The cylindrical part is engaged with the cylindrical part to form an accommodating groove capable of accommodating and holding the end of the webbing cover, and is formed on a wide surface and separates the accommodating groove to join the webbing. and an auxiliary member having a spacing part that allows the joint part of the webbing cover to escape and securely maintains the holding of the webbing cover, and also maintains the position of 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. This has an excellent effect in that the webbing cover does not follow the winding of the webbing and the winding is smoothly performed.
