PURPOSE:To facilitate mounting of a seat belt by rotating a rotary arm that engages an outer belt on one end and supports the other end on a car body as soon as a driver is seated and moving the outer belt and a tongue plate forward. CONSTITUTION:Before a driver takes a car, a rotary arm 1 and a guide plate 2 are energized by springs 20 and 21, respectively and an outer belt 5 is located as shown in the figure. Then, when the driver takes the car and is seated, a shaft 9 is pressed down by the weight and the guide plate 2 is rotated counterclockwise through a wire 12. At the same time, the rotary arm 1 is pushed in the same direction through a button 15 and the outer belt 5 is moved up to the side of the driver. As a result, when the driver takes up the tongue plate 4 and inserts it in a buckle 8, the lever in the buckle 8 is swayed and a wire 13 is pulled. The button 15 is retreated and the rotary arm 1 returns to the initial position by the spring 20. |
