Abstract

The apparatus locks the safety belt at the same time the automobile brake acts, by installing a built-in magnet simultaneously magnetizing according to the motion of the brake pedal rod. The safety belt quick-stopping apparatus comprises a push bar (6a) formed in the magnet (6) and pushing a brake plate (12a) in the case of being magnetized; a lead wire (6') connected to a switch (6) for sensing the motion of the break pedal rod (7) and a brake display lamp (9); ratchet wheels (11) positioned in both sides of a bobbin (2); the brake plate (12) having a projected end for stopping the rotation of the lachet wheels (11) and rotated in the center of a pin (12b) and supported by a spring (13).

The present invention relates to a rapid braking device of a seat seat belt, and in particular, by installing an electromagnet which is operated at the same time during the flow between brake pedals into an existing belt case, the seat belt sudden braking device to achieve a perfect seat belt braking effect simultaneously with vehicle braking. It is about.

The various safety belts currently in use are equipped with various types of emergency lock mechanisms in the case where the belt is wound to promote the safety of the belt wearer while preventing the safety belt from being released during braking of the vehicle.

In the above seat belt, since the operating principle of the lock mechanism is to be operated by the inertia during vehicle braking, there was no time difference between the vehicle braking time and the seat belt locking time. As the belt is pulled out by a considerable length, the belt braking is performed by the lock mechanism, which causes the belt wearer sitting on the seat to jump out of the front axle and return to its original position. Of course, it had an undesirable effect on the belt itself.

The present invention has been researched and developed in order to solve this problem, the electromagnet which is to be operated at the same time when the flow between the brake pedal is installed in the existing seat belt case and installed on both sides of the bobbin the push bar and the belt of the electromagnet is wound The seat belt always enters the braking state when the driver presses the brake pedal by providing a braking device that allows the ratchet wheel to be fixed while being rotated by the push bar by installing a braking plate of appropriate type between the ratchet wheels that are fixedly installed. The purpose is to increase the safety promotion effect of passengers.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 1 to 3, the bobbin 2, in which the belt 1 of appropriate length is wound, is fixedly fixed to the pivot shaft 4 on the seat belt case 3 with the fixing key 4a. The bobbin 2 is a push bar 6a which can be mounted on the bottom plate 5 of the case 3 in a general seat belt in which belt braking is performed by a lock device (not shown) using an inertial principle. ) Is installed and the power line 6 'of the electromagnet 6 is a power line between the sensing switch 8 and the vehicle braking light 9 which detects whether the brake pedal 7 is flowing. 10, the push bar 6a of the electromagnet 6 is pulled out and the ratchet wheels 11 are attached to both sides of the bobbin 2 to connect the ratchet wheels. Interposed between the brake plate 12 with the locking end 12a formed between the 11 and the electromagnet 6a, and the brake plate 12 is pivoted about the shaft pin 12b, and the brake plate 12 and the bottom are 5 is a spring 13 between gwaeji is configured to return the push bar (6a) and the copper plate 12.

In the figure, reference numeral 14 denotes a fixing screw of the electromagnet 6 and 15 denotes a master cylinder.

According to the present invention having the above configuration, the electromagnet 6 and the brake plate 12 are installed in respective seat belt cases 3 installed in the vehicle, and the power line 6 ′ of the electromagnet 6 has a brake pedal ( Installation is completed by connecting the power supply line 10 to the power supply line 10 between the sensing switch 8 and the vehicle brake light 9 for detecting whether the flow of the 7).

As the driver steps on the brake pedal 7 while driving, the vehicle brake light 9 lights up.At the same time, the push bar 6a of the electromagnet 6 is pulled out and accordingly the brake plate is in contact with the end of the push bar 6a. As the 12 is rotated about the shaft pin 12b, the locking end 12a of the brake plate 12 rests on the teeth 11a of the ratchet wheel 11 fixed to both sides of the bobbin 2.

At this time, while preventing the pivoting operation of the bobbin (2) is to enter the braking state to fully control the further belt pull-out operation.

When the vehicle brake light 9 is turned off in the driver's brake pedal 7, the electromagnet 6 is also switched off, and the push bar 6a and the brake plate 12 are caused by their own weight and elasticity of the spring 13. The braking of the seat belt is released by returning to the original position.

In this case, the belt braking state is applied to all the seat belts in the vehicle in a state of sudden braking by simply stepping on the brake pedal (7), such as when braking the vehicle or decelerating to reduce the vehicle speed. The effect is to ensure the maximum safety of the wearer.

As described above, the present invention solves all problems such as safety deterioration caused by using the seat belt to enter the braking state by using only the emergency lock device to operate by the inertia generated during the braking of the vehicle as in the related art. It is effectively resolved.

In particular, it is a very excellent invention that extends the service life of the belt itself by increasing the safety promotion effect of the passengers by allowing all the seat belts in the vehicle to enter the braking state at the same time as the vehicle brake light is turned on. .
