1. A directional trigger mechanism responsive to an inertial force for explosively deploying a passenger-restraining safety device in a vehicle independently of the electrical system of the vehicle comprising a support member having an elongated body portion provided with a first passage extending along the length thereof and a side extension projecting from said body portion and having a side passage extending laterally from said first passage along the entire length of said side extension;

  • an elongated inertial mass having an actuator on one end thereof and a spherical camming surface on the opposite end thereof, said inertial mass being positioned within said side passage for slidable movement therealong between a cocked position and an actuating position in response to said inertial force;

    a pair of drive spheres of substantially the same diameter as the spherical camming surface coaxially positioned within said first passage on opposite sides of the camming surface, said spherical camming surface being disposed within the intersection of said passages with its geometric center displaced relative to the aligned centers of the drive spheres when the inertial mass is in its cocked position and said actuator projecting outwardly from said side passage when the inertial mass is in its actuating position;

    as biasing means constantly biasing said drive spheres into intimate engagement with said spherical camming surface for releasably retaining said inertial mass within its cocked position and driving said actuator toward its actuating position upon release from its cocked position.
