Crash sensor with improved activation for stabbing primer

In a crash sensor of the type comprising a first resilient means for storing energy, an element movable in response to deceleration forces during a crash, and release means adapted to release the energy stored in said first resilient means upon movement of said element to a predetermined position, the improvement comprising:

• said release means coacting with said first resilient means for constraining it in a stressed state for storing energy,
• and said release means comprising a ring having plural trigger levers extending inward.

In a crash sensor of the type comprising a first resilient means for storing energy, an element movable in response to deceleration forces during a crash, and release means adapted to release the energy stored in said first resilient means upon movement of said element to a predetermined position, the improvement comprising:

• said release means comprising trigger means linked with said first resilient means for movement therewith and wherein,
• said trigger means urges said movable element away from said predetermined position by using energy stored in said first resilient means.

In an occupant protection system of an automotive vehicle of the type comprising multiple crash sensors located near each other and each adapted to pierce a stab primer and initiate a chemical reaction in response to deceleration forces during a crash, the improvement comprising:

• each of said crash sensors being a unitary structure adapted to be placed in an occupant protection system,
• said crash sensors being grouped in manufactured which have one or more manufacturing circumstances in common,
• each sensor of said multiple crash sensors being drawn from a different one of said groups.
