Seatbelt control apparatus
First Claim
1. A seatbelt apparatus comprising:
- a seatbelt;
a spool for retracting the seatbelt;
a motor for rotatably driving the spool;
urging mechanism for urging the seatbelt toward a retracting direction;
belt attaching/detaching mechanism adapted to attach/detach the seatbelt for fastening or releasing the seatbelt,belt releasing detecting mechanism for detecting that the seatbelt is released from the belt attaching/detaching mechanism; and
motor controller configured to cause the motor to start to take up the seatbelt when a predetermined amount of time passes since the belt releasing detecting mechanism detects that the seatbelt is released.

Abstract
A seatbelt apparatus including a seatbelt, a spool for retracting the seatbelt, a motor for rotatably driving the spool, and urging mechanism for urging the seatbelt toward a retracting direction. The seat belt apparatus further includes belt attaching/detaching mechanism, a belt releasing detecting mechanism and, and a motor controller. The belt attaching/detaching mechanism fastens or releases the seatbelt. The belt releasing detecting mechanism detects that the seatbelt is released from the belt attaching/detaching mechanism. The motor controller causes the motor to start to take up the seatbelt on the condition that a predetermined amount of time passes since the belt releasing detecting mechanism detects that the seatbelt is released.

3. A seatbelt control apparatus that controls an apparatus including a seatbelt, a spool for retracting the seatbelt, a motor for rotatably driving the spool, urging mechanism for urging the seatbelt toward a retracting direction;
- and belt attaching/detaching mechanism adapted to attach/detach the seatbelt for fastening or releasing the seatbelt, the seatbelt control apparatus comprising;
a belt releasing detecting mechanism for detecting that the seatbelt is released from the belt attaching/detaching mechanism; and a motor controller configured to cause the motor to start to take up the seatbelt on the condition that a predetermined amount of time passes since the belt releasing detecting mechanism detects that the seatbelt is released.

4. A seatbelt control method for controlling an apparatus which includes a seatbelt, a spool for retracting the seatbelt, a motor for rotatably driving the spool, urging mechanism for urging the seatbelt toward a retracting direction, and belt attaching/detaching mechanism adapted to attach/detach the seatbelt for fastening or releasing the seatbelt, the seatbelt control method comprising:
-
determining an amount of time during which an urging force of the urging mechanism becomes weaker than a predetermined level; detecting that the seatbelt is released from the belt attaching/detaching mechanism; and causing the motor to start to take up the seatbelt on the condition that the amount of time determined in the first step passes since the second step detects that the seatbelt is released.

5. A method of controlling an apparatus which includes a seatbelt, a spool for retracting the seatbelt, a motor for rotatably driving the spool, urging mechanism for urging the seatbelt toward a retracting direction, and belt attaching/detaching mechanism adapted to attach/detach the seatbelt for fastening or releasing the seatbelt, the method comprising the steps of:
-
a belt releasing detecting step of detecting that the seatbelt is released from the belt attaching/detaching mechanism; and a motor control step of causing the motor to start to take up the seatbelt on the condition that a predetermined amount of time passes since the belt releasing detecting step detects that the seatbelt is released.
