Abstract
A mechanism including: a toggle link rotatably connected to a base structure; a stop connected to the base structure for limiting a rotational travel of the toggle link; a biasing element having a first end attached to the base structure and a second end attached to the toggle link such that the toggle link is biased towards the stop when the toggle link is positioned on a first side of a singular position and the toggle link is biased towards an opposite direction from the stop when the toggle link is positioned on a second side of the singular position; and an inertial element movably disposed between the base structure and the toggle link such that that inertial element moves the toggle link from the first side of the singular position to the second side of the singular position when the base structure undergoes an acceleration event greater than a predetermined threshold.
