Abstract:
1. A seat belt apparatus comprising: a webbing reel that winds a webbing to hold an occupant of a vehicle; a motor that is connected to the webbing reel via a transmission mechanism; a clutch member that is movable to a connecting position at which the motor and the webbing reel are maintained in a connecting state, and that is movable to a disconnecting position at which the motor and the webbing reel are maintained in a disconnecting state; a belt reacher device that is arranged to be movable in a forward and a backward direction of the vehicle around an axis in an outward direction with respect to a vehicle compartment from a passenger seat, moves around in the forward direction of the vehicle by a biasing member, and moves around to a retracted position in the backward direction of the vehicle by winding of the webbing; a seating detection unit that detects whether or not the occupant is seated in the passenger seat; a start-up state-detection unit that detects a start-up state of the vehicle; a door opening/closing-detection unit that detects opening and closing of a door of the vehicle; and a control unit that controls the motor, wherein, in response to the door opening/closing-detection unit detecting a change from an open state to a closed state of the door, the control unit controls driving of the motor such that the clutch member is moved to the disconnecting position and thereby the belt reacher device is moved around in the forward direction of the vehicle by the biasing member, and wherein, in response to the seating detection unit detecting no occupant seated in the passenger seat and the start-up state-detection unit detecting the start-up of the vehicle, the control unit controls the driving of the motor such that the webbing is wound and thereby the belt reacher device is moved around to the retracted position in the backward direction of the vehicle.
