ABSTRACT:
A deceleration sensor for detection for deceleration greater than a certain threshold level, comprising: a firing pin; a sensor mass which is guided for motion along a first direction in a casing and is urged by a first spring member along the first direction so as to oppose an inertia force that will be applied to the sensor mass as it experiences deceleration which is to be detected; a trigger arm which is pivoted at its base end and comprises a first free end which is urged by a second spring member into activating the firing pin and a second free end which is engaged with the sensor mass so as to oppose a rotational motion of the trigger arm under a biasing force of the second spring member; and a shoulder surface provided in the sensor mass for holding the trigger arm against the biasing force of the second spring member be being engaged with the trigger arm under a normal condition and releasing the trigger arm by being disengaged from the trigger arm when the sensor mass experiences acceleration greater than the threshold level. Since the frictional force involved in the engagement between the sensor mass and the trigger arm is drastically reduced, the state of the engagement can be controlled very precisely.
