Abstract:
A seat belt device attached to a seat with a seat back and a seat cushion, comprising:a seat belt retractor including a retractor frame adapted to be attached to the seat back, a reel attached to the retractor frame for winding a seat belt, a locking mechanism attached to the retractor frame for locking a rotation of the seat belt in a withdrawing direction, and an acceleration sensor for activating the locking mechanism, said acceleration sensor being supported on the retractor frame to tilt around a horizontal axis and having a sensor weight which tilts due to an acceleration in a horizontal direction,a rotor engaging the acceleration sensor for controlling a posture of the acceleration sensor, said rotor allowing the acceleration sensor to align vertically,a rotational member adapted to be attached to a support for the seat, said rotational member rotating corresponding to an inclination of the seat back, anda connecting member connecting the rotational member and the rotor so that the acceleration sensor always orients vertically regardless of an inclined angle of the seat back.
