Method for rotating a toggle link upon an acceleration event greater than a predetermined threshold

A mechanism comprising:

• a toggle link rotatably connected to a base structure;
• a stop fixed to the base structure for limiting a rotational travel of the toggle link, the stop being fixed to the base structure such that there is no relative movement between the stop and the base structure;
• 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 relative to the base structure and the toggle link such that the 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.
