Abstract
Abstract A device for sensing a level of acceleration lasting for a given time period and initiating a response thereto. An element movable in response to acceleration forces carries an actuator member and also a trigger mechanism that has a rotatable finger to normally hold the actuator member, actuation of the trigger mechanism being controlled by a cam that swings the finger after a predetermined movement.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
An acceleration-sensitive actuator device comprising an acceleration-responsive element, means for urging said element in a first direction, an actuator member carried by said element having a latch extending therefrom, trigger means including first and second rotatably mounted fingers carried by said element and normally cooperating in complementary engagement with the latch of said actuator member for maintaining said actuator member in an initial position with respect to said acceleration-responsive element, and cam means having first complementary cam surfaces converging in a direction opposite said first direction of predetermined length with a cam height sufficient to hold said fingers in engagement with said latch and second complementary cam surfaces adjacent said first cam surfaces having a reduced cam height for releasing said fingers from engagement with said latch for maintaining said fingers in said cooperating relationship for a predetermined element movement and for releasing said fingers and freeing the actuator member for movement with respect to said element.
Claim 2
Dependent Claim
157 words
An acceleration-sensitive actuator device comprising an acceleration-responsive element, means for urging said element in a first direction, an actuator member carried by said element having a latch extending therefrom, trigger means including first and second rotatably mounted fingers carried by said element and normally cooperating in complementary engagement with the latch of said actuator member for maintaining said actuator member in an initial position with respect to said acceleration-responsive element, and cam means having first complementary cam surfaces converging in a direction opposite said first direction of predetermined length with a cam height sufficient to hold said fingers in engagement with said latch and second complementary cam surfaces adjacent said first cam surfaces having a reduced cam height for releasing said fingers from engagement with said latch for maintaining said fingers in said cooperating relationship for a predetermined element movement and for releasing said fingers and freeing the actuator member for movement with respect to said element.
Claim 3
Dependent Claim
40 words
The device of claim 1 including means for fixing said cam means from movement in said first direction and for permitting movement in a direction lateral to said firs direction as said fingers move along said cam means cam surfaces.
Claim 4
Dependent Claim
37 words
The device of claim 1 including an additional locking means engaged with said acceleration responsive element and said actuator member for blocking movement thereof and means for disengaging said locking means from said element and said member.
