Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a suspension stopper device for a seat belt for an automobile, which is used when the seat belt is worn inside the vehicle.

Conventional technology Conventionally, a seat belt 20 attached to a car
For example, as shown in FIG. 8, the end of the
The ring part of the hook support part 21 is passed through, and the hook is pulled from the shoulder toward the side in a swivel shape, and the fastening tool at the tip is fixed to the fixing tool of the seat. This seatbelt has a stopper attachment device on the inner wall and inside the vehicle body that prevents the stop from being pulled out even if there is a sudden pulling force. It can be pulled out depending on the situation. The seat belt is configured to elastically return to the vehicle body when this slow tension is released.

When the seat belt 20, which is attached to the body in a sash-like manner as described above, is fixed by the stopper piece 23 of the belt stopper 22, the seat belt 20 is fixed and attached in the direction of the tensile force (arrow C) drawn into the vehicle body. People are now freed from the feeling of being confined.

Of course, when the seat belt is pulled due to a sudden shock, the belt stopper 22 becomes unfixed due to the tension, and is protected by a stopper attachment device inside the vehicle body.

Problems to be Solved by the Invention In the above configuration, when the seat belt is worn, when the seat belt is pulled, the seat belt 20 is pulled diagonally through the hook support part 21, so when the seat belt is fastened by the belt stopper 22, In many cases, the seat belt was stopped at an inclined position (see Fig. 10), and there was a problem that the seat belt was not stable and could slip or loosen.

The present invention solves the above-mentioned difficulties, and provides a suspension system for an automobile seat belt in which the stopper device does not shift in position relative to the seat belt at all times, and the seat belt can be securely fixed by the rollers and reverse rotation prevention mechanism. The purpose is to provide a stopper device.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention includes a suspension part suspended from a hook support part attached to an inside column of an automobile, and a suspension part that is rotatably attached via the suspension part and a crank. The stopper is composed of an overlapping end edge formed by overlapping two U-shaped cross-sectional frames facing each other, and a bridge between the overlapping end edges to enable rotation of the two U-shaped cross-sectional frames. a shaft support integrally connected to the shaft support, a spring biased to further overlap the overlapping end edges of the U-shaped frames around the shaft support, and attached to two shafts bridged to each of the U-shaped frames These two rollers are urged to come into close contact with each other by the spring, and are inserted into a notch provided in the overlapping end edge, and the two rollers are The suspension stopper device for an automobile seat belt is characterized by comprising a lever for separating a roller.

Function In the present invention, the device of the present invention can be easily installed by a suspension part suspended from a hook support part in a car, and after installation, the stopper, which is rotatable via a crank, is moved by the movement of the crank. It is designed to maintain a position parallel to the tension direction of the seat belt at all times. And this stopper is 2
An overlapping edge portion in which two U-shaped cross-sectional frames are stacked facing each other, and a pivot support that is bridged between the overlapping edge portions and is rotatable so as to overlap and separate the two U-shaped cross-sectional frames. and is biased by a spring so that the U-shaped frames are further overlapped around this pivot support.

Therefore, it is pivotally supported by each of the U-shaped frames,
With two rollers equipped with a reverse rotation prevention mechanism, the seatbelt passed between the rollers can be freely pulled out in a certain direction, that is, in the direction in which the driver pulls it by hand, but the seatbelt cannot be returned to the direction in which it is retracted. Since the seat belt is clamped in such a way that the seat belt can be attached to the body in a sash-like manner with some allowance once it has been pulled out. This mounted state can be released using a lever that separates the two rollers.

Embodiment The drawings show an embodiment, in which numeral 1 is a column inside a car, 2 is a hook support part, which is attached to the column 1 with a shaft 3.

Reference numeral 4 denotes a suspension part that can be installed by engaging with the hook support part 2. Reference numeral 5 denotes a crank, which is pivotally supported by the hook support part 2 and the stopper 6, and both are rotatably attached.

The stopper 6 is made by stacking two U-shaped cross-sectional frames 7 and 8 facing each other, and the overlapping end edge 9
has. The two U-shaped cross-sectional frames 7, 8 are connected by the shaft support 10 bridged between the overlapping edge portions 9, 9.
are rotatably coupled together.

Reference numeral 11 denotes a spring which urges the overlapping end edges 9 of the U-shaped frames 7 and 8 to be further overlapped about the shaft support 10. Reference numerals 12 and 13 denote shafts, which are bridged to each of the U-shaped frames 7 and 8, each having two rollers 14, 14, 15, and 15, and a ratchet type anti-reverse mechanism 16 in the center. roller 1
4 and 15 can be fixed more reliably by using elastic materials with sponge or the like stretched on the surface.

Reference numeral 17 denotes a lever, which is attached to the U-shaped frame 8 and inserted through a notch 18 provided in the overlapping end edge 9. By pushing this notch open, the spring 1
Two rollers 14, 14,
15, 15 can be separated from each other. 19 indicates a seat belt.

Since this embodiment has the above-mentioned configuration, the hook support part 2 provided on the pillar inside the car by the suspension part 4
The stopper device is attached by suspending it from the holder. The seat belt 19 is connected to the rollers 14,1
5, 14, and 15, and is inserted into the vehicle body by passing over the suspension portion 4, and is constantly urged to be pulled into the vehicle body (as shown by arrow A). (see directions).

The stopper 6 is connected to the suspension part 4 via the crank 5.
Since the stopper 6 is rotatably attached to the seat belt, when the seat belt user pulls the seat belt in the B direction, the crank 5 also pulls the stopper 6 in the B direction. Therefore, the stopper 6 is always maintained in a position parallel to the seat belt 19, and the seat belt is always securely fixed by the stopper 6.

The seat belt 19 is prevented from rotating in the opposite direction (direction A) by the ratchet-type reversal prevention mechanism 16, so when it is pulled in the direction B and adjusted to the body when worn, it will stay in place with plenty of room. ,A
Since there is no pulling force in any direction, you will not feel cramped. It should be noted that the end portion of the seat belt 19 that is pulled in the direction B when the seat belt is worn is completely the same as the conventional method in that the end portion of the seat belt 19 is engaged and fixed with a fastening device of the seat.

In the event of an emergency, when a sudden tensile force in direction B is applied to the seat belt 19, the rollers 14, 1
5, 14, and 15 rotate, this tensile force is applied directly to the mounting device inside the vehicle body, stopping the extension in direction B, preventing the body from leaning forward, and maintaining safety. .

When removing the seat belt 19, when the lever 17 is lowered along the notch 18, the two U-shaped frames 7, 8 are separated against the elastic force of the spring 11, so that the rollers 14, 15 The pinched state of the seatbelt is released, and the seatbelt 19 is pulled in the direction A and is removed from the fastened state, and the seatbelt is also shortened.

In the illustration, a ratchet type mechanism is used for the roller reversal prevention mechanism, but the present invention is not limited to this, and a gear mechanism or other mechanism may be used.
Further, although the semicircular spring shown in the drawing is a structure in which two U-shaped frames are biased in the direction of overlapping each other around the shaft support, this is not limited to this. Although the shape of the stopper 6 is also shown to be rectangular, it may be any other shape as long as the two U-shaped frames can be brought into close contact and separated from each other at the shaft support and the belt can be clamped and fixed by the rollers.

Effects of the Invention Since the present invention has the above-described configuration, the stopper device is suspended from the hook support portion inside the vehicle by the suspension portion, and the seat belt is constantly subjected to tensile force from below the vehicle body. It is designed to be clamped and fixed between rollers in a stopper via a suspension part of the device.

Since the roller is equipped with a reverse rotation prevention mechanism, it can be pulled out freely when the seat belt is pulled slowly, making it easy to put on the seat belt. Furthermore, once the seat belt is pulled out and put on, the reversal prevention mechanism prevents the belt from returning, making it possible to wear the seat belt properly without feeling cramped. Furthermore, the stopper, which is rotatably attached to the suspension part via a crank, always moves parallel to the tension direction of the seatbelt, so that the seatbelt is always held in a constant and stable state between the rollers. It is now possible to obtain a certain standard.

In an emergency, when a sudden tensile force is applied to the seatbelt, the rollers are designed to prevent the body from jumping out or leaning forward by the emergency locking mechanism inside the vehicle, regardless of the reverse rotation prevention mechanism. .

When removing the seatbelt, the seatbelt can be easily shortened and stored by separating the two U-shaped frames using a lever, making it safe and secure, and making it easy to reach inside the car. Since the stopper can be provided within the range, it is possible to provide a suspension stopper device for an automobile seat belt which has various effects such as ease of use.
