Abstract: A seatbelt buckle device includes a buckle switch (40) having a switch substrate (42) and a slider part (50) which slides on the switch substrate (42) and a frame (20) which has a substantially U-shaped section and slidably holds an ejector (30) which operates synchronously with attachment/detachment of a tongue plate (1). The buckle switch (40) and the frame (20) are assembled integrally with each other as the a leg part (43) as a rear end of the switch substrate (42) is fixed to a side wall (22A) of the frame (20) through a switch substrate housing (45) and thus supported by the frame (20).

Abstract: 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.
