Provided is a seatbelt device capable of reliably securing and protecting a passenger. This seatbelt device has a first seatbelt tension increasing unit ( ) for increasing the tension of the seatbelt ( ), and a second seatbelt tension increasing unit ( ) for increasing the tension of the seatbelt ( ). When this seatbelt device judges that the collision of a vehicle is unavoidable, it operates the first seatbelt tension increasing unit ( ) before the collision and operates the second seatbelt tension increasing unit ( ) when it detects the collision of the vehicle. Thereby, the passenger is reliably secured to the seat and his/her safety is ensured.

Seatbelt device

The present invention provides a seat belt system comprising: a moving element ( ) rotatably received in a housing ( ); a device ( ) for applying a pressurized gas to the moving element ( ) when abrupt deceleration occurs on a vehicle; a tensile member ( ) responsive to movement of the moving element ( ) extruded due to the pressurized gas to generate a rotational torque; and a clutch mechanism ( ) for transmitting the rotational torque generated by the tensile member ( ) to a retractor shaft ( ) to rotate the shaft ( ) in a webbing-winding direction.

Seat belt system

A seatbelt system is provided with a retractor, which has a retractor base provided with side plates, a bobbin, a locking member prevented from rotation in a webbing-withdrawing direction in an event of an emergency, a shaft integrally connected at an end thereof with the bobbin and at an opposite end thereof with the locking member, and a bobbin locking mechanism for preventing rotation of the bobbin in the webbing-withdrawing direction when relative rotation between the bobbin and the locking member has reached a predetermined extent. The locking member is brought into engagement with one of the side plates of the retractor base so that any further rotation of the locking member is prevented. At the same time, the bobbin is brought into engagement with the other side plate via the bobbin locking mechanism so that any further rotation of the bobbin is prevented.
