An emergency buckle 24 serving as a belt anchor part 25 is attached to the front end of the tip 23b of the movable pole 22, and a tip 37 of the shoulder belt B is attached to the emergency buckle 24.

The base end of the shoulder belt B is provided at the center of the vehicle floor or is attached to a tractor (not shown) so that it can be wound and pulled out.

Furthermore, a lock hole 26 is bored approximately on the rear side of the belt anchor portion 25 of the movable pole 23 to engage with a lock pin 31 serving as a locking means provided on the vehicle body side pillar 29, which will be described later. .

On the other hand, the movable pole 23 engaged with the guide rail 21
One end of a geared wire 27 is attached to the base end 23a of the movable pole 23, and the movable pole 23 is driven by a motor 28, etc., which is operated by the geared wire 27 and a door switch (not shown) that is turned on and off by opening and closing the door A. The device moves along the guide rail 21 toward the front of the door when opening the door, and toward the rear when closing the door.

In this embodiment, the driving device is constituted by a motor, a geared wire, etc., but the driving device is not limited to this, as long as it moves the movable pole back and forth by opening and closing a door.

A cylindrical mounting member 30 is attached to the vehicle body side pillar 29 corresponding to the stop position of the movable pole 23 when the shoulder belt B is attached and corresponding to the lock hole 26 formed in the movable pole 23. A lock pin 31 having a tapered portion 31a whose tip is inclined forward is attached, and the lock pin 31 is attached to a spring 3 built in the attachment member 30.
2, the tip is always urged to protrude.

Therefore, when the door A is closed, as shown in FIG.
6, the moving pole 23 is prevented from moving forward, but is free in the opening/closing direction of the door A.

Therefore, as shown in FIG. 6, when the door A is opened, the lock pin 31 is disengaged and the belt anchor part 25 of the movable pole 23 is moved to the height when the shoulder belt B is attached. The movable pole 23 can be moved forward while maintaining the position.

In order to move the movable pole 23 after the movable pole 23 and the lock pin 31 are completely disengaged, a delay circuit may be provided in the driving device circuit, or a switch may be installed on the locking device side. It is desirable to provide one.

Further, as shown in FIG. 7, when the door A is closed, the movable pole 23 moves rearward, and presses the tapered portion 31a of the lock pin 31 with the rear edge of the movable pole 23. is temporarily pushed into the mounting member 30 against the spring force of the spring 32, and when the movable pole 23 comes to the rear position, that is, the shoulder belt B attachment position, as shown in FIG. The lock pin 31 is inserted into and engaged with the lock hole 26 of the movable pole 23.

In this embodiment, the movable pole 23 is locked by the lock pin 31 provided on the vehicle body side pillar 29, but it may be locked to the door A side by an appropriate locking device. Alternatively, it may be locked to both.

35 is an inner lining, and 36 is a weather strip.

As described above, according to the present invention, a guide rail extending linearly near the upper edge of the door panel is provided, and the tip of the guide rail extends upward to approximately the height of the shoulder of the occupant. A movable pole is slidably installed, the movable pole is movable by a drive device provided in the door panel, and the distal end of the shoulder belt is attached to the distal end of the movable pole. Since the structure is such that at least one of the vehicle body or the door corresponding to the stop position of the movable pole when the shoulder belt is attached is provided with a locking means to prevent the movable pole from moving forward, the movable pole will not move when the door is opened. A portion of the belt anchor on the pole can be moved to the front of the door while maintaining the height when the shoulder belt is attached.

Therefore, the shoulder belt does not get in the way when getting on and off, improving the ease of getting on and off, and when putting on the shoulder belt, the shoulder belt does not move from a low position in front of the vehicle as in the case of conventional methods. There is no risk that the shoulder belt will enter the armpit.

Furthermore, according to the present invention, since the movable pole that is moved back and forth along the guide rail is provided on the door, the shoulder belt attached to the movable pole moves to the outside of the vehicle compartment together with the door immediately after the door is opened. while moving forward.

Therefore, the occupant can exit the vehicle even if the movable pole has not completely moved to the front.

Further, even if the movable pole drive device fails, the ease of getting in and out of the vehicle will be worse than before the failure, but by opening the door, the occupant will no longer be affected by the shoulder belt and will be able to get out of the vehicle.

It is also possible to ride in the same way.

Furthermore, since the guide rail of the present invention is linear, it has the advantage that the movable pole can move more smoothly than a guide rail using a curved rail.
