The excitation circuit 18 of the relay coil 17b has a relay 19 and a transistor Tr, and the base terminal of the transistor Tr has a collision coil 1Tb that operates to open when a vehicle collides. The switch 20 and the timer circuit 21 are connected, and under normal conditions, due to the open state of the collision switch 20, the transistor Tr is in the OFF state, the relay coil 17b is not excited, and the relay contact 17a is closed.
When the door 4 is opened, the motor 9 is driven in reverse rotation to keep the operation control circuit 12 closed and move the upper end 5b of the seatbelt 5 forward. In the event of a vehicle collision, the collision switch 20 is closed and the transistor Turn on the Tr to excite the relay coil 17b, and
By opening the relay contact 17a by the excitation of b, the operation control circuit 12 is opened when the door 4 is opened, disabling the rotational drive of the motor 9, and the collision switch 20 is immediately activated immediately after a collision. Even if the motor 9 is opened, the timer circuit 21 is configured to keep the motor 9 in an inoperative state for a certain period of time.

するようにしたものである。The timer circuit 21 includes, for example, a first resistor R1 with a small resistance value and a second resistor R2 with a large resistance value, as shown in FIG.
, a diode 22, and a capacitor 23. When the collision switch 20 closes in the event of a collision, current from the battery 19 immediately flows through the first resistor R1 with a small resistance value to the base terminal of the transistor Tr, and the transistor Tr is On the other hand, even if the collision switch 20 is opened after a collision, the current stored in the capacitor 23 will be
The voltage gradually flows through the resistor R2 to the base terminal of the transistor Tr, and the ON state of the transistor Tr is maintained for a certain period of time.

The weight contact 24 swings and comes into contact with the fixed contact 25 due to the impact at the time of a collision.
この衝突スイッチ２０は車体１の７０ア等で局部振動の
少ない剛性の高い箇所に設置するのが、誤動作を防止す
