Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a passive seat belt device for a set of movable anchors installed in an automobile.

Conventionally, in a passive seat belt device with a set of moving anchors attached to a car, if the moving device of the anchor breaks down for some reason, there is a risk that it will not be possible to remove it. In order to make this possible, many proposals have been made to provide a buckle on the moving anchor and to make the thing attached to the end of the belt removable, so that in the event of a failure, the tongue can be removed from the buckle and the belt released. There was nothing that could be worn at times.

. The present invention has been made to solve the above-mentioned conventional drawbacks, and even if the anchor moving device breaks down and the anchor stops at a position where it cannot be attached, such as at the front end of the guide rail, the belt can be removed from the anchor. It is an object of the present invention to provide a passive seat belt device in which a belt can be fixed and attached to a fixed anchor having a buckle separately provided on a vehicle body.

The present invention will be described below with reference to illustrative embodiments.

11 is a guide rail, and 12 is a movable anchor. The proximal end of the movable anchor 12 is fixed to a slider 13 that is slidably inserted into the guide rail 11.

Further, a buckle 14 is integrally formed at the tip of the movable anchor 12, so that a tongue 16 attached to one end of a shoulder belt 15 can be removed.

29 is a fixed anchor having a buckle fixed above the center pillar 30 of the vehicle body, and the shape and structure of the buckle are as follows, and is similar to the buckle 14 formed on the movable anchor 12 above. It is a structure.

17 is a lock plate, 18 is a pressing piece, 19 is a spring plate, 20 is a stopper, and 32 is an attachment portion to the vehicle body.

The buckle 14, movable anchor 12, and fixed anchor 29's buckle part and the attachment part to the vehicle body are molded separately.
It may also be attached to the mobile anchor 12 or the vehicle body.

21 is a drive motor operated by a door switch (not shown) that is turned ON and OFF when the door is opened and closed; 22;
25.31 is a drive pulley that rotates via gears 23 and 24 by the operation of the drive motor 21, and 25.31 is a guide pulley.
26 is a wire belt, which is attached to the guide rail 11.
Each of the pulleys 22, 25 and 31
The negative side of the slider 13 freely passes through the inside of the slider 13, and pressing pieces 27a and 27b are fixed to the front and rear thereof with an appropriate interval (play).

Reference numeral 28 denotes a locking member having a locking claw 28a that engages with the slider 13. Normally, the locking member 28 is pressed in the engaging direction by a spring 33, but when the slider 13 comes to the belt attachment position, this locking member 28 After being pushed up, the lock pawl 28a of the locking member 28 is engaged with the engagement hole 13a of the slider 13 to lock the slider 13.

Also, when releasing, the protrusion 2 of the locking member 28 is attached to the pressing piece 27a.
8b is pressed to release the engagement.

With the above configuration, when the shoulder belt 15 is attached, that is, when it is in the position A shown in FIG. The user is released from wearing the shoulder belt 15 and can get off the vehicle.

Furthermore, if the moving device malfunctions in the position before installation, for example the mouth position shown in FIG. A belt 15 can be attached.

As described above, according to the present invention, a buckle is provided on the moving vehicle, and a tongue is attached to the end of the shoulder belt to make it removable. Even if the moving device fails and the moving anchor does not move, the shoulder belt can be released by removing the tongue and the rider can get off the vehicle.

Furthermore, according to the present invention, a fixed anchor with a buckle is also provided on the center pillar of the vehicle body, so when the movable anchor is in the front, even if the movable device breaks down and the shoulder belt cannot be attached, Since the shoulder belt can be attached by replacing the tongue with the fixed anchor, the shoulder belt can be attached even if the vehicle breaks down while the vehicle is running.

[Brief explanation of the drawing]

Fig. 1 is a perspective view of the passive seat belt device according to the present invention as seen from the inside of the vehicle, Fig. 2 is an enlarged longitudinal cross-sectional view showing the relationship between the fixed anchor having a buckle and the tongue, and Fig. 3 is the driving anchor. FIG. 4 is an enlarged side view of the main part showing the attached state of the same, and FIG. 4 is a longitudinal cross-sectional view of the same. 11 is a guide rail, 12 is a movable anchor, 14 is a buckle, 15 is a shoulder belt, 16 is a tongue, 21 is a drive motor, 29 is a fixed anchor, and 30 is a center pillar.
