Abstract
A pendulum-like, impact-responsive switch is provided to disconnect the battery from the electrical system of a car in the event of a collision to thereby prevent the ignition by sparking wires of fuel and other flammable material. Means are provided to control the force-level responsiveness of the pendulum-like member and to hold the member in de-activated position.
Claims4
A collision-responsive safety switch for a vehicle operable to disconnect the battery from the rest of the electrical system of the vehicle when the vehicle collides with another vehicle or object, said switch comprising a lever arm disposed for pivotal movement about an axis which extends transversely of the normal path of movement of the vehicle, an electrical conductor extending transversely of said arm and movable with said arm, a pair of contact members, means supporting said members, said members being adapted to be interconnected by said conductor when said arm is in a vertical position, one of said contacts being connected to the battery of the vehicle and the other being connected to the rest of the electrical system of the vehicle, holding means and means positioning the same to selectively retain the arm at one end or the other of its arc of swing to maintain the battery and the rest of the electrical system in disconnected relation, and means for variably controlling the amount of force required to swing said arm to disconnect the battery from the rest of the electrical system.
A collision-responsive safety switch for a vehicle operable to disconnect the battery from the rest of the electrical system of the vehicle when the vehicle collides with another vehicle or object, said switch comprising a housing, a lever arm disposed within said housing for pivotal movement about an axis which extends transversely of the normal path of movement of the vehicle, an electrical conductor extending transversely of said arm and movable with said arm, a pair of contact members carried by said housing and adapted to be interconnected by said conductor when said arm is in a vertical position, one of said contacts being connected to the battery of the vehicle and the other being connected to the rest of the electrical system of the vehicle, the upper end of said arm being free, weighted, and magnetically responsive, the lower end of said arm being fixed and pivotable, a pair of magnets carried by said housing to selectively retain the arm at one end or the other of its arc of swing to maintain the battery and the rest of the electrical system in disconnected relation, and means for variably controlling the amount of force required to swing said arm to disconnect the battery from the rest of the electrical system.
