摘要： An overlock prevention mechanism for a vehicle acceleration sensor used on a retractor for a seat belt device in a vehicle comprises an inertial body which moves in response to acceleration of the vehicle; a sensor casing on which the inertial body is mounted; a ratchet wheel which locks the retractor; and a composite sensor arm assembly comprising an upper sensor arm which is adapted to be engaged with the ratchet wheel and a lower sensor arm which is adapted to come into contact with the inertial body to transmit the movement of the inertial body to the upper sensor arm; and when the upper sensor arm is interlocked with the ratchet wheel, the lower sensor arm is forced toward the inertial body by a force activated from the ratchet wheel and transmitted through the upper sensor arm, so that the inertial body is pressed to the sensor casing against movement.
