Right side view of the belt fixing device, Figure 8 is a longitudinal cross-sectional view of the seat belt fixing device according to the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in Figure 1, the seat belt fixing device according to the present invention is not particularly limited to the fixing method such as fixing the fixing plate 61 to the vehicle body 11 using a screw or double-sided adhesive, but sudden stop or accident In order to provide a screw connection is preferable. As described above, the seat belt fixing device is fixed to the vehicle body, and the seat belt 12 is sandwiched between two cylinders. As shown in FIG. 6, both sides of the driving unit 21 have a fixed shaft 51 coupled to the fixed shaft member 52, but only one side of the fixed unit 21 has the fixed shaft 51 and the fixed shaft member 52. ) And the other side is open, so that the seat belt 12 is inserted between the driving unit 21 and the fixing unit 31 so that the driving unit 21 and the fixing unit ( 31) can be rotated.

As shown in FIG. 1 and FIG. 6, the fixed shaft member 52 is vertically coupled to the vehicle body 11, and the driving unit 21 and the fixing unit 31 are coupled to each other in parallel with the ground to be engaged and rotated. It is.

FIG. 2 illustrates a state in which the seat belt 12 is fixed between the driving unit 21 and the fixing unit 31 so that the seat belt 12 is not moved in the rewinding direction of the actual seat belt 12. It is.

As shown in FIGS. 2 and 4, when the belt 12 is pulled to wear the seat belt 12, the drive unit 21 rotates by a friction force between the drive unit 21 and the seat belt 12, and one side of the drive unit 21 is rotated. The drive part gear 22 formed at the end rotates together, and the fixed part gear 32 meshed with the drive part gear 22 also rotates, and thus the fixed part 31 also rotates.

As described above, when the seat belt 12 is pulled, the fixing part 31 rotates. The cross-sectional shape of the fixing part 31 has a shape in which a portion of the top and bottom of the circle is cut off. When rotated over a certain angle it is not in contact with the seat belt 12 is shown in Figures 3 and 5. Therefore, when the seat belt 12 is pulled out and the seat belt 12 is released as shown in FIGS. 3 and 5, the seat belt 12 is not fixed and is rewound again.

Therefore, in order to rewind the seat belt 12 without being fixed, it is only necessary to release the seat belt 12 when it is in the state shown in FIGS. 3 and 5.

6 and 7 illustrate a process for preventing the seat belt 12 from being rewound by the rewinder in the seat belt 12 when the seat belt 12 is worn by the present invention. As shown in FIG. 7, when the seat belt 12 is raised upward to wear the seat belt 12, the driving unit 21 and the driving unit gear 22 rotate to the right side, and the fixing unit 31 and the fixing unit 31 are fixed. The gear 32 and the ratchet gear 33 are rotated to the left. At this time, the locking portion 41 is located on the surface of the ratchet gear 33 does not interfere with the rotation to the left, but hinders the rotation to the right. Therefore, when the seat belt 12 is released after wearing the seat belt 12 at an appropriate pressure, the catching portion 41 ratchets the seat belt 12 downward by the rewinding device in the seat belt 12. By preventing the rotation of the gear 33, our body is released from the feeling of pressure of the seat belt (12).

As shown in FIG. 6, in order to engage the ratchet gear 33 with the ratchet gear 33, an upper portion of the '-' shaped stopper guide 42 is coupled to the penetrating portion 41 and the lower portion thereof. It is connected with this fixed shaft member 52, and the spring 43 is located between them. In addition, in order to precisely restrict the ratchet gear 33 from rotating in the reverse direction, the auxiliary guide 44 is positioned at the end of the locking portion 41. That is, the auxiliary guide 44 serves to prevent the latch portion from rotating downward when the ratchet gear 33 rotates in the reverse direction.

8 is a view showing a state in which the locking portion 41 does not interfere with the reverse rotation of the ratchet gear 33 so that the seat belt fixing device according to the present invention can play a role of the seat belt in a sudden or crashing of the vehicle. will be.

8 (a) is a cross-sectional view showing a state in which the vehicle is in a normal state or when the vehicle is suddenly stopped or collided. FIG. 8 (a) shows a state in which the vehicle moves in the direction indicated by the arrow in FIG. In this case, due to the inertia of the locking portion 41 itself, the locking portion 41 moves in the direction of the arrow, and the ratchet gear 33 is released from the fixed state, thereby freeing the rotation of the fixing portion 31 and having the safety belt itself. The function of the rewinder and the function of the seat belt itself are properly exercised to prevent the occupant from jumping out of the vehicle.

After that, the locking portion 41 returns to its original position by the action of the spring 43 installed on the locking portion guide 42, thereby preventing the ratchet gear 33 from rotating backward.
