An occupant information sensing deviceincludes a plurality of heater electrodes that are provided at a vehicle steering wheeland insulated and separated from one another and that generate heat by conduction. Power sources provide electrical current for heater electrodes. Electrical circuit elements enable the system to provide occupant biological condition monitoring, gripping detection, and electrical stimulation. The circuits enable common electrical connecting to the heater electrodes to provide multiple functions through the use of filtering and time division multiplexing.

An occupant protection system includes a winding shaft that winds up a seat belt; a reacher rotatably supported by a rotating shaft and which changes the position of the seat belt in a front-back direction of a vehicle; a biasing member biasing the reacher to turn in a front direction of the vehicle; a retraction detection unit detects that the reacher is in a rear position; a motor rotates the winding shaft in a winding direction and a pull-out direction of the seat belt; a current detection unit detects the motor current; and a control unit The control unit is configured to change the rotating direction of the motor to the pull-out direction when the motor is rotating in the direction of winding up the seat belt, the reacher is not in the rear position, and the motor current is a predetermined current value or higher.

A seat belt retractor may include: a motor that generates a driving force for retracting and unreeling a seat belt by rotating a shaft, a gear case has an interior portion that houses a gear that converts a rotary force of the shaft into a driving force, a harness connected to a side of the motor including the shaft that is disposed opposite the gear case, a motor case having an opening disposed in only one end thereof, and a motor cap disposed on a side of the motor including the shaft opposing the gear case. The motor cap may include a passage portion through which the harness passes to an exterior thereof. The opening in the motor case may be sealed by attaching the motor case to the motor cap and the gear case in a sandwiched manner.
