Embodiments of the present invention will now be described with reference to the drawings, and the drawbacks of the above-described conventional occupant protection device will be more specifically clarified with reference to the drawings.

FIG. 1 is a side view of a so-called open body vehicle which is an example of a vehicle with a removable door. The door 1 is rotatably supported by the vehicle body 3 via a pair of hinge devices 2 and 102 arranged vertically. As shown in FIG. 2, these hinge devices 2 and 102 respectively have vehicle body side hinge pieces 4 and 104 fixed to the vehicle body 3 and door side hinge pieces 5 and 105 fixed to the door 1. Piece 5,
Reference numeral 105 has pins 6 and 106 extending vertically, and brackets 7 and 107 that fix the pins to the door 2 immovably. Further, the vehicle body side hinge pieces 4 and 104 are provided with curling portions 8 to which the pins 6 and 106 are detachably fitted, respectively.
The door 1 is opened and closed in the direction of arrow A with respect to the vehicle body 3 around the two concentric pins 6 and 106 fitted in the curl portions 8 and 108.

When removing the door 1 from the vehicle body 3, the door 1
The pin 6, 106 and the curls 8, 10
Just pull out from 8. To mount the door 1 on the vehicle body 3, conversely, the pins 6 and 106 may be inserted into the curl portions 8 and 108, and the operation is extremely simple. As described above, the hinge devices 2 and 102 serve to pivotally support the door 1 with respect to the vehicle body 3.

FIG. 3 shows the state of the vehicle body 3 when the door is removed. At this time, the door opening 9 after the door is removed is exposed to the outside. Therefore, since it is dangerous to drive the vehicle with this as it is, the occupant protection device 10 protects the occupant.

As shown in FIGS. 4 and 5, the protective device 10 has a flexible protective belt 11 which is bridged over the door opening 9 after the door is removed. One end side of the belt 11 is
In the illustrated example, the loop portion 1 formed by winding the belt itself on the rear end side and sewing the outermost end portion to the belt.
2 is provided, and the anchor plate 13 is provided on the loop portion 12.
Is installed. This anchor plate 13 is the vehicle body 3
It is fixed to the pillar 14 by bolts 15 and nuts. Thus, the rear end side of the protective belt 11 is connected to the vehicle body 3 by the connecting means including the anchor plate 13, the bolt 15 and the nut. Anchor plate 13
May be rotatably connected to the bolt 15.

Further, the other end side of the protective belt 11, that is, the front end side in the illustrated example, is detachably engaged with the vehicle body 3 by the belt attaching / detaching means 16. Before the details of the attaching / detaching means 16 will be described. For the understanding of the invention, the structure of the conventional attaching / detaching means is clarified.

As shown in FIG. 9, the conventional belt attaching / detaching means is a ring-shaped base member 50 attached to the front end side of the protective belt 11, and is attached to the base member 50 so as to be swingable in the direction of arrow B. A substantially C-shaped latch member 51 and a spring 52 provided in the opening thereof and elastically deformable in the direction of arrow C.
And a striker 53 fixed to the vehicle body 3 and having a substantially U-shape
And have. When the front end side of the protective belt 11 is locked to the vehicle body 3, the latch member 51 is engaged with the striker 53 as shown in FIG. 9 while elastically deforming the spring 52 in the direction of arrow C. Also, when the front end side of the protective belt 11 is detached from the vehicle body 3, the occupant uses his / her finger to move the spring 52 with the arrow C.
The latch member 51 may be removed from the striker 53 by pushing it in the direction to elastically deform it.

As described above, the front end side of the protective belt 11 can be attached to and detached from the vehicle body 3 even by the conventional belt attaching / detaching means, but the number of parts constituting the protective belt 11 is very large and the cost becomes high. . Moreover, when the latch member 51 is attached to or detached from the striker 53, the spring 52 must be elastically deformed each time, so that the operation is complicated. In particular, when the latch member 51 is removed from the striker 53, if the occupant wears gloves, it is difficult to push the spring 52 with a finger, and the operability is significantly reduced.

Therefore, the belt attaching / detaching means 16 of the occupant protection apparatus 10 according to the present invention shown in FIGS. 1 to 7 is a hinge on the vehicle body side of the above-mentioned hinge apparatus 2 for detachably pivoting the door 1 to the vehicle body 3. It is composed of a piece 4 and an engaging piece composed of a hook 17 attached to the other end side of the protective belt 11, that is, a front end side in this example. The hook 17 is formed by bending a metal rod or the like into a ring shape, and the front end of the belt 11 is formed with a loop portion 18 having the outermost end thereof sewn to the belt itself, and the loop portion 18 is hooked. 17 bases 19 are fitted.

After the door 1 is removed from the vehicle body 3 as described above, the belt 11 is stretched so as to bridge the door opening 9, and the hook 17 on the front side thereof is removed as shown in FIG. The curled portion 8 of the rear vehicle body side hinge piece 4 is inserted from above. In this way, the protective belt 11
Can be bridged over the door opening 9, and the vehicle can be driven safely. When an occupant gets in and out of the vehicle, or when the door 1 is attached to the vehicle body 3 again, the hook 17 may simply be lifted upward and removed from the curl portion 8. This allows the protective belt 11 to be removed from the door opening 9.

According to the above structure, the belt attaching / detaching means 16
Is made up of two parts, the hook 17 and the hinge piece 4 on the vehicle body side, and the number of parts is significantly smaller than in the conventional case. Moreover, the vehicle body side hinge piece 4 is originally a constituent element of the hinge device 2, and the only component that actually needs to be provided as the belt attaching / detaching means 16 is the hook 17.

To attach and detach the vehicle body side hinge piece 4 and the hook 17, simply insert the hook 17 into the curl portion 8,
Alternatively, it is only necessary to extract this, which is extremely easy. Even when the occupant is wearing gloves, the attachment / detachment operation can be performed extremely easily.

As shown in FIG. 8, the vehicle body side hinge piece 4 of the hinge device 2 which removably supports the door 1 on the vehicle body 3 has a pin 21 fixed to the curl portion 8 as shown in FIG. When a door-side hinge piece (not shown) having a door is fixed, and the curl portion on the door side is engaged with the pin 21 to pivotally support the door on the vehicle body, as shown in FIG. An engagement piece having a curl portion 22 may be attached to the front end side of the protective belt 11. Also in this case, after removing the door, the curl portion 22 of the engaging piece may be fitted to the pin 21 of the vehicle body side hinge piece 4, and the belt 11 may be bridged over the door opening 9.

In the illustrated example, the rear end side of the protective belt 11 is connected to the vehicle body 3 by the connecting means composed of the anchor plate 13, the bolt 15 and the nut.
For example, as used in a normal seat belt, the rear end side of the protective belt may be attached to a retractor mounted on the vehicle body, and the belt 11 may be wound around the retractor when not in use. In this example, the connecting means is a retractor.

[0020]

According to the vehicle occupant protection system of the present invention, the number of parts of the belt attaching / detaching means for detachably locking the other end side of the protective belt to the vehicle body can be reduced, and the cost thereof can be reduced. At the time of the attachment / detachment operation, it suffices to insert / remove the vehicle body side hinge piece and the engaging piece attached to the protective belt, and the operability is remarkably enhanced.
