Abstract

PURPOSE:To dispense with a quarter pillar by providing a slit having width narrower than a mounting bolt in a sash guide mounting hole to disengage the sash guide from the quarter pillar upon large tensile action of webing in an emergency and change an anchor point. CONSTITUTION:A sash guide 30 is mounted on a quarter pillar 14 by a bolt 34 to provide an anchor point of a webing 18. A bolt mounting hole 36 of the sash guide 30 is provided with a slit 38 having the width narrower than the diameter of the bolt 34. Thus, a large tensile force F acting on the webing 18 with impact in an emergency disengages the sash guide 30 from the quarter pillar. Thus, since any large force does not act on the quarter pillar any, reinforcement is not needed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat belt device for use in a seat belt device for protecting an occupant during a vehicle emergency. The actual anchor point can be changed by attaching it to the sash guide device.

This satshu guide device has a guide ring attached to the tip of the satshu guide body, one end of which is fixed to the vehicle body, and the middle part of the webbing is inserted through this guide ring. The system is designed to ensure that the vehicle is properly installed and to improve safety in vehicle emergencies.

These sash guide devices are all fixed to the vehicle body, and are designed to ensure that the large tension generated in the webbing is supported by the vehicle body in the event of a vehicle emergency.

However, in vehicles with a gently sloping roof at the rear of the vehicle (called a first/quarter roof), the pillars (quarter pillars) that support the rear of the roof are relatively thin. When installing the quarter pillar, it is necessary to install many reinforcing materials inside the quarter pillar to ensure the strength of the quarter pillar, which leads to an increase in cost and vehicle weight.

The present invention takes the above-mentioned facts into account, and provides an object that can reliably withstand the webbing tension that occurs during normal vehicle operation, secures an anchor point during normal vehicle operation, and reliably separates from the single unit and changes the anchor point in the event of a vehicle emergency. The purpose is to obtain a plant guide device that can perform the following steps.

In the sash guide device according to the present invention, a through hole and a slit communicating with the entire outside of the through hole are formed in the sash guide main body to which a guy pilling for webbing insertion is attached, and a mounting bolt is screwed into the vehicle body through the through hole. It is securely attached to the vehicle body during normal vehicle operation and forms an anchor point.
In the case of a vehicle emergency, the sash guide body moves relative to the mounting bolt due to the large tension generated in the webbing, and the mounting bolt passes through the slit, allowing the sash guide body to detach from the vehicle body and change the anchor point.

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

FIG. 1 shows a sash guide device 1 according to an embodiment of the present invention.
The structure shown is that 0 is attached to a quarter pillar 14 that connects the rear of the vehicle body side wall 12 and the rear end of the roof (not shown).

A winding device 16 is attached to the vehicle rear end of the side wall 12, and winds up one end of the occupant restraining webbing 18. The other end of this webbing 18 is the quarter pillar 1
4, the winding device 16 and the satsugai 13 device 10
After passing through the slip joint 20 installed between the sash guide device 10 and the sash guide device 10, the sash guide device 10 is extended toward the front of the vehicle, and reaches a mounting portion for an occupant (not shown).

16 is a side wall 12-\frame 22 fixed to the winding device
A winding shaft (not shown) is rotatably supported on the winding shaft, and this winding shaft winds up the webbing 18 with a predetermined effort using a spring winding device 24.In the event of a vehicle emergency, an inertia lock mechanism (not shown) allows the winding shaft to wind up the webbing 18 with a predetermined effort. It is designed to instantly stop 18 drawers.

Slip join) 2 (H webbing insertion ring 2
6 is fixed to the quarter pillar 14, and the webbing 18 can freely pass through this ring 26. This slip joint 20 forms an anchor point for the webbing 18 to the quarter pillar 14 in case of a vehicle emergency.

The sash guide device 10 will be explained in detail with reference to FIGS. 2 and 3. This satshu guide device 10 has a guide ring 28
and a satshu guide body 30.

The guide ring 28 is an iron round bar whose axis is bent into an oval shape and has a webbing insertion hole 32 formed therein. .

Part of the sash guide main body 30 is made of a thin steel plate, and a through hole 36 into which a mounting bolt 34 is inserted is formed approximately in the center. This through hole 36 is a slit 38
communicates with the outside world. It is preferable that the width of this slit 380 is slightly smaller than the outer diameter of the threaded portion of the mounting bolt 34, and by changing the width of this slit 38, the load when the sash guide device 10 is removed can be adjusted. Can be done. Further, the axis 4o of this slit 38 is directed upward and rearward of the vehicle when it is attached to the quarter pillar 14.

The sash guide main body 3o has a bent portion 42 on the front side of the vehicle as well as the mounting tilt 34 when attached to the quarter pillar 14, and an extension portion 44 projects toward the interior. The distal end of the extension part 44 surrounds a part of the guide ring 28, thereby ensuring that the guide ring 28 is supported on the dowel guide body 30. In order to securely attach the guide ring 28 and the extension portion 44, fixing means such as welding may be applied.

As a result, the guide ring 28 and the slit 38 are placed on opposite sides of the bent portion 42.

An abutment plate 46 bent at right angles extends from the sash guide main body 3o, and this abutment plate 46 is in close contact with the surface of the quarter pillar 14.

This prevents the sash guide main body 3o from inadvertently rotating around the mounting belt 34 during normal vehicle operation.

Sash guide device 1 of this embodiment configured as described above
The operating state of 0 will be explained.

When attaching it to the car body, attach the guide ring 28 in advance.
The installation of the sash guide device 10 is completed by passing the mounting bolt 34 through the through hole 36 of the sash guide main body 30 through which the webbing 18 has been inserted, and by tightening the mounting bolt 34 to the quarter pillar 14.

During normal vehicle operation, the guide ring 28 forms an anchor point for the webbing 18 that acts as shoulder webbing, and transfers the webbing tension generated by the winding force of the winding device 16, changes in driving posture of the occupant, etc. to the quarter pillar 1.
4 to give the occupant an appropriate state of wearing the webbing. The sash guide main body 30 is in close contact with the Fortabi 2-14 by the tightening force of the mounting belt 34, and the abutment plate 46 is also in close contact with the surface of the quarter pillar 14. It will not rotate, and the anchor point will not change due to pulling force from the occupant.

When the vehicle is in an emergency situation such as a collision, the occupant moves in the direction of the collision due to inertia, so a large tension is generated in the longitudinal direction of the webbing 18 as shown by arrow A in FIG. By being supported by the winding device W16, the wind guide device 10 is pulled downward in the front of the vehicle as shown by arrow F in FIG.

Since this load F is extremely large, the satshu guide body 3
0 is slightly rotated in the direction of arrow B by the mounting bolt 34 times 9, and the slit axis 40 approaches the direction of load F.

At the same time, the sash guide main body 30 moves in the direction of the load F, the mounting bolt 34 moves relative to the slit 38, and the sash guide main body 30 separates from the quarter pillar 14 by passing through the slit 38.

Since the slit 38 has an outer width dimension smaller than the outer diameter dimension of the mounting bolt 34, the mounting bolt 34 moves relative to the sash guide main body 30 while pushing the slit 38 apart, and the load F is set in advance. When the set value is reached, the satshu guide device fl 1.0 will be disengaged.

In particular, since the extension part 44 of the sash guide main body 30 is arranged further forward of the vehicle than the mounting bolt 34, the sash guide main body 30 is less deformed than when it is arranged further behind the vehicle than the mounting bolt 34, and the slit axis can be reliably aligned. 4
0 can be placed in the load F direction.

When the sash guide device 10 is detached from the mounting belt 34 and the quarter pillar 14, the webbing 18 is supported by the slip joint 20 to the quarter pillar 14, and the slip joint 20 is attached to the quarter pillar 14.
Since the webbing 18 is firmly fixed to the webbing 18, the large tension generated in the webbing 18 is reliably supported by the vehicle body, ensuring the safety of the occupants.

Since the large tension generated in the webbing 18 is transmitted to the quarter pillar 14 via the slip joint 20, both the slip joint 20 and the side wall 12 of the vehicle body
Mounting y+ located in a part far from ? The strength of the quarter pillar 14 can be lowered compared to the case where the webbing tension is supported by the quarter pillar 14 at the root 34 portion.

Further, after the satshu guide device 10 is detached from the mounting bolt 34, the quarter pillar 14 is attached to the mounting bolt 34.
Since only the sharp protrusions remain on the quarter pillar 14 and no other sharp protrusions remain on the quarter pillar 14, safety is high.

Although the above embodiment shows a structure in which the present invention is applied to a sash guide device for supporting shoulder webbing to a quarter pillar, the present invention also applies to other webbing such as lap webbing to other parts of the vehicle body such as the vehicle roof. Naturally, the locking structure can also be applied to 6 blades.

As explained above, in the sash guide device according to the present invention, since the sash guide body is detachably attached to the vehicle body, it has an excellent effect that a temporary anchor point can be easily obtained during normal vehicle operation.
