1. A device comprising:
- an impact mass movably restrained relative to a base; and
a release mechanism configured to be movable between a restrained position for preventing movement of the impact mass and a released position for permitting movement of the impact mass when the release mechanism is subjected to an acceleration greater than a predetermined magnitude and duration the release mechanism having a release mass movable when subjected to the acceleration;
wherein the release mechanism is configured such that a force is not applied from the impact mass to the release mass when the impact mass is subjected to the acceleration.

15. A method for moving an impact mass upon the impact mass experiencing an acceleration greater than a predetermined magnitude and duration, the method comprising:
movably restraining the impact mass relative to a base; moving a release mechanism between a restrained position for preventing movement of the impact mass and a released position for permitting movement of the impact mass when the release mechanism is subjected to the acceleration; configuring the release mechanism to have a release mass movable when subjected to the acceleration, wherein the release mechanism does not apply a force to the release mass when the impact mass is subjected to the acceleration. - View Dependent Claims (16, 17, 18, 19, 20)
