Description

[Detailed Description of the Invention] The present invention relates to a webbing cover used in a seat belt device for protecting occupants in a vehicle emergency.

In a seatbelt device, a webbing for restraining an occupant is worn by the occupant, and the webbing restrains the occupant in the event of a vehicle emergency, thereby improving the safety of the occupant.

However, the shoulder webbing, which restrains the occupant's upper body diagonally, often moves relative to the occupant's upper body when the occupant changes his or her driving position during normal vehicle operation, causing wear on the occupant's clothing and the wear and tear of ornaments such as brooches. This may cause them to fall off the passenger. In particular, when an occupant rides the vehicle wearing clothes that expose bare skin near the shoulders, the webbing may come into contact with the occupant's bare skin and cause discomfort.

For this reason, conventional structures have been proposed in which a flexible cover is provided in the middle of the webbing to prevent the webbing from coming into direct contact with the passenger, but this increases the thickness of the webbing substantially, so after the webbing is removed, There is a problem that the webbing cannot be wound onto the winding device.

Taking the above facts into consideration, the present invention covers the part of the shoulder webbing that comes in contact with the passenger so that it does not cause discomfort to the passenger, and also prevents the webbing from being wound up and stored in the retracting device after the webbing is released. The purpose is to obtain a webbing cover that does not have any problems.

The webbing cover according to the present invention includes a cover strap whose one end is attached to a passenger seat, a storage device that applies a retracting force to the cover strap, and a storage device that is provided at the tip of the cover strap so that the cover strap can be pulled out when the cover strap is pulled out. a locking member disposed toward the passenger side of the shoulder webbing; a cover strap side member integrally provided at the tip of the cover strap; and a cover strap side member integrally provided at the middle portion of the shoulder webbing and arranged in the mounting direction of the shoulder webbing. A shoulder webbing side member that comes into contact with the cover strap side member when the shoulder webbing is moved to apply a pulling force from the accommodation device to the cover strap, and is separated from the cover strap side member when the shoulder webbing is moved in the direction in which the shoulder webbing is not attached. It's summery.

Therefore, when attaching the shoulder webbing, the shoulder webbing side member comes into contact with the cover strap side member as the shoulder webbing moves in the attaching direction, and the cover strap is pulled out from the storage device. When the shoulder webbing is uninstalled, the shoulder webbing side member is separated from the cover strap side member by movement of the shoulder webbing in the non-installation direction, and the cover strap is is designed so that it does not interfere with the winding of the shoulder webbing.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a seatbelt device to which the webbing cover 10 according to the present embodiment is applied, and in this seatbelt device, the webbing 12 is
This is used to restrain the occupant 16 seated on the seat 14 in the event of a vehicle emergency.

That is, one end of the webbing 12 is secured to the vehicle body side wall 20 via an anchor plate 18, and the middle portion of the webbing 12 is wound onto a take-up device 26 after passing through a tongue plate 22, a webbing cover 10, and a through ring 24. It has been taken. This winding device 26 is attached above the anchor plate 18 on the side wall 20 of the vehicle body, and winds up the webbing 12 with a biasing force, and in the event of a vehicle emergency, instantly stops pulling out the webbing 12 to restrain the occupant. It's becoming like that.

The tongue plate 22 has a webbing 12 inserted through an elongated hole 28, and can be engaged with a buckle device 32 erected from a vehicle body floor 30 on the opposite side of the anchor plate 18 via a seat 14. . Also, the through ring 24 is connected to the anchor bolt 3.
4 is fixed to the upper part of the vehicle body side wall 20, and the middle part of the webbing 12 is folded back at a long hole 36.

Therefore, when the occupant 16 seats the seat 14 and engages the tongue plate 22 with the buckle device 32, the webbing 12 in the take-up device 26 will move in the mounting direction, that is, pass through the through ring 24 and move toward the tongue plate 22. (in the direction of arrow A) to make the occupant wear a three-point seat belt. When this webbing is attached, the area between the anchor plate 18 and the tongue plate 22 is used as a wrap webbing, and the area between the tongue plate 22 and the through ring 24 is attached as a shoulder webbing to the occupant.

The webbing cover 10 of this embodiment uses a cover strap 38 to eliminate discomfort to the occupant. The cover strap 38 is in the form of a plate made of a flexible material such as a woven material such as wool, silk, or linen, and one longitudinal end of the cover strap 38 is wound onto a winding device 40, which is a storage device.

The winding device 40 is built in near the upper end of the passenger seat 14 and closer to the side wall 20 of the vehicle body.
As shown in FIG. 3, this winding device 40 has a base frame 42 fixed to a frame 46 of the sheet 14 with bolts 44. This base frame 4
A winding shaft 50 is pivotally supported by a pair of legs 48 that stand up from both ends of the winding shaft 2, and one end of a cover strap 38 is fixed to the center of the winding shaft 50. Also, one end of this winding shaft 50 and one leg portion 48
A spring spring winding means 52 is provided between the two and winds the cover strap 38 with a biasing force.

However, since a large load will not be applied to this winding device 40 even in a vehicle emergency, it can be made to have a lightweight and low-strength structure.

The middle part of the cover strap 38 protrudes outward from an opening provided at the upper end of the sheet 14, and the distal end goes around one long side of the rectangular ring 54 shown in FIGS. 5 and 6 and is folded back and then sewn. It is worn. Therefore, the rectangular ring 54 is connected to the cover strap 3.
It is attached to the tip of 8. The middle portion of the webbing 12 is inserted into the rectangular opening 56 of the rectangular ring 54.

Here, the rectangular ring 54 restricts the webbing 12 from rotating around the longitudinal axis within the rectangular opening 56. In other words, the rectangular ring 54 serves as a locking member that always positions the cover strap 38 on one side of the shoulder webbing facing the passenger 16.

Further, a bar 58 provided at the middle portion of the webbing 12 corresponds to this rectangular ring 54. This bar 58 is sewn to the middle part of the webbing 12 by applying a sewing thread 62 through a through hole 60 formed in the middle part. As a result, the bar 58 substantially increases the thickness of the middle portion of the webbing 12, and comes to interfere with the rectangular ring 54 when the webbing 12 is inserted through the rectangular opening 56 of the rectangular ring 54.

Here, the bar 58 is attached closer to the through ring 24 than the rectangular ring 54, and when the webbing 12 moves in the mounting direction (arrow A direction), it interferes with the rectangular ring 54 and winds the cover strap 38. The sheet 1 resists the urging force of the taking device 40.
4, and on the other hand, when moving in the non-installation direction (direction opposite to arrow A), pull out the bar 58.
is adapted to move in a direction away from the rectangular ring 54 to apply a force to the cover strap 38.

Therefore, the rectangular ring 54 also serves as a cover strap side member, and the bar 58 serves as a shoulder webbing side member.

Note that instead of this bar 58, other means such as overlapping and sewing the middle parts of the webbing 12 can be applied, and any protrusion that substantially increases the thickness of the middle part of the webbing 12 can be applied. It is.

Next, the operation of the above embodiment will be explained. When the passenger seats on the seat 14 and engages the tongue plate 22 with the buckle device 32, the first,
As shown in FIG. 2, the webbing 12 allows a three-point seatbelt to be worn.

Webbing 1 according to this webbing installation operation.
2 moves from the through ring 24 in the webbing attachment direction (direction of arrow A), so the bar 58 attached to the middle part of the webbing 12 moves from the through ring 24 to the rectangular ring 54.
The cover strap 38 interferes with the winding device 40.
Unroll from. Since the rectangular opening 56 of the rectangular ring 54 always positions the cover strap 38 on the occupant 16 side of the webbing 12, the cover strap 38, which is made of a flexible material, comes into contact with the occupant 16. As a result, even if the passenger 16 is wearing clothes that expose the bare skin of the shoulders, a comfortable driving posture can be obtained.

When the vehicle is in an emergency situation such as a collision, the winding device 26 instantly stops unwinding the webbing 12, so the occupant 16 is securely restrained by the webbing 12, thereby ensuring safety. In this case, a bar 58 attached to the middle part of the webbing 12
applies a force in the direction of pulling out the cover strap 38 from the take-up device 40, but the length of the cover strap 38 must be determined so as to ensure a sufficient remaining length of the cover strap 38 inside the take-up device 40. cover strap 38 and winding device 40
No unnecessarily large force is applied to the

When the passenger exits the vehicle, the tongue plate 22 is removed from the buckle device 32 and the webbing 1 is removed.
2 is the biasing force of the winding device 26 in the non-installation direction (arrow A
(in the opposite direction), allowing passengers to easily exit the vehicle. In this case, bar 5 of webbing 12
8 moves in the direction away from the rectangular ring 54, so it does not apply any force to the cover strap 38. On the other hand, the cover strap 38 is accommodated within the sheet 14 by the winding force of the winding device 40. Therefore, as shown in FIG. 7, the cover strap 38 does not interfere with the movement of the webbing 12, the webbing 12 is appropriately wound onto the take-up device 26, and the webbing 12 does not interfere with the occupant's ability to get off the vehicle.

When the webbing 12 is reinstalled, the tongue plate 22 is located at the shoulder of the seat 14, so the passenger can easily grasp it and perform the installation operation.

Next, FIG. 8 shows a second embodiment of the present invention, which is another embodiment of the cover strap storage device.

In this embodiment, one end of the cover strap 38 is secured to a frame 46 within the seat 14;
The end portion of the cover strap 38 is wrapped around a roller 64 within the sheet 14 and bent into a U-shape. This roller 64 is biased downwardly by a tension coil spring 66.

Therefore, in this embodiment, the cover strap 38 is bent into the seat 14 in a U-shape, and the same effects as in the previous embodiment can also be obtained.

In addition, the present invention is not limited to the above-mentioned storage devices, and can use various storage devices.
In addition to the configuration in which it is provided inside, it is also possible to provide it in other parts such as the rear side of the seat 14. Furthermore, the ring 54 of the above embodiment is not limited to a rectangular shape, but can be applied to any shape that allows the cover strap 38 to be placed on the passenger side of the webbing 12 when being pulled out, and that interferes with the protrusion in the middle of the webbing when the webbing 12 is moved in the longitudinal direction. A portion of the cover strap 38 may be a wire attached to the cover strap 38 by sewing means or the like. Further, if a notch is provided in a part of the ring 54 to communicate the inside and outside of the ring 54, it is easy to insert the webbing into the ring and the assembly is convenient.

In the above configuration, if the shoulder webbing is positioned by providing a guide through which the middle part of the webbing 12 between the through ring 24 and the rectangular ring 54 can be inserted into the upper end of the seat 14, the cover strap 38 and the shoulder webbing can be positioned. The rubber webbing is in close contact with the other, eliminating any misalignment between the two.

As explained above, the webbing cover according to the present invention includes a cover strap whose one end is attached to the passenger seat, a storage device which applies a pulling force to the cover strap, and a webbing cover which is provided at the tip of the cover strap and which is attached to the cover strap. A locking member that positions the cover strap on the passenger side of the shoulder webbing when the cover strap is pulled out, a cover strap side member that is integrally provided at the tip of the cover strap, and a locking member that is integrally provided at the middle part of the shoulder webbing that is attached to the shoulder webbing. a shoulder webbing side member that comes into contact with the cover strap side member when the webbing is moved in the mounting direction to apply a pulling force from the accommodation device to the cover strap, and separates from the cover strap side member when the shoulder webbing is moved in the non-wearing direction; When the occupant wears the webbing, a flexible material is placed between the occupant and the webbing to eliminate discomfort for the occupant.
This has an excellent effect of not interfering with the winding operation of the webbing when the webbing is not attached.
