Patent ID: 7766389

Claim:
A seatbelt apparatus for a vehicle, comprising: a belt reel having a belt wound thereon; a motor for rotationally driving the belt reel to take up the belt; rotational position detecting means for detecting a rotational position of the belt reel; control means for, on the basis of an output signal from the rotational position detecting means, controlling an amount of electric power to be supplied to the motor; door opened/closed state detecting means for detecting an opening/closed state of a door of the vehicle; and inhibiting means for inhibiting the motor from being driven when it determines, on the basis of an output signal from the rotational position detecting means, that variation in the rotational position of the belt reel, which is less than or equal to a predetermined value, has occurred, on condition that the door opened/closed state detecting means detects that the door has shifted from a closed state to an opened state.
