The contactor for firing a pyrotechnique charge comprises a support base (6) made of an insulating material and having at least two conducting terminals (7 and 8), a contact sleeve (13) centered coaxially on the base and in contact with one of the terminals, having pins which can be centrifugally displaced by elastic element (22), a deformable, conductive case (24) in contact with the second terminal, and a conductive slide-bar (28) which can move under inertia on the axis of symmetry against the effect of a retaining spring (31). Application as impact contactor for projectiles. |

Impact sensor in motor vehicles with a safety system such as an air bag or belt tensioner for a passenger-restraining system. The sensor is arranged in the electrical circuit of a trip circuit of the safety system, which is closed by the action of an acceleration or deceleration over a given time-interval. |

A method for initiating a thermal battery including: releasing an engagement between an element and a striker mass upon an acceleration time and magnitude greater than a first threshold; and moving at least one member into a path of the element to prevent the element from releasing the striker mass only where the acceleration time and magnitude is greater than a second threshold, the second threshold being greater than the first threshold. |

A bidirectional accelerometric isolator comprises a box, at least one pair of elelctric contact pins facing one another in the box and an arrangement for reversing the electrical continuity state of the pins in the box. This arrangement includes a first mass sensitive to an acceleration of the box in a first direction in order to move to an arming position in which the mass is automatically rendered integral by a lock with a second mass, the first and second joined masses then being sensitive to an acceleration of the box in a second direction which is opposite to the first so that they move into an actuating position reversing the electrical continuity state of said pins. The isloator has particular application to fields requiring the making or breaking of d.c. or pulse-type currents, particularly those of a very high level, following two successive accelerations of the isolator in opposite directions, such as in aerospace, robotics and particularly in constraining environments. |

An acceleration sensor comprises a housing formed with a hollow cavity deing a sensing direction. An acceleration sensing conductive mass is releasably mounted in the cavity. The mass is released by a cutting member which severs the releasable mounting of the acceleration sensing mass. A force applying assembly is activated to cause movement of the cutting member. Switch electrodes are arranged at the lower end of the housing cavity. The mass falls through a predetermined distance and bridges the switch electrodes. The sensing mass, when severed, may move in incremental steps due to the use of a two-stage releasing assembly. Sensing transducers may be located along the falling path of the acceleration sensing conductive mass. |

A detector secured to a projectile, which closes a switch at the end of a deceleration period after an initial acceleration period of the projectile. The detector components are housed in a small cylindrical container having two normally open switch terminals. A movable mass is resiliently positioned at one end of the detector to act as an inertia operator to drive a latch through a wall when a deceleration of the projectile is sensed. When the projectile comes to rest, the movable mass is returned to its original position and the switch is closed.

A sensor includes a housing mounted on a vehicle body for swinging movement about a vertically disposed pin. A coiled torsion spring mounted on the pin normally locates the housing in a predetermined position with respect to the supporting body structure. Mounted within the housing are a pair of normally closed switch contacts. A lever swingably mounted within the housing for movement about a generally horizontally disposed axis adjacent its lower end mounts a weight adjacent its upper end. A permanent magnet normally locates the lever in a predetermined position in engagement with an insulating abutment on one of the switch contacts to maintain the switch in open position. When an acceleration pulse of predetermined amplitude and time is received, the housing moves about the pin until it is oriented or aligned with the general direction of such pulse. Upon orientation being achieved, the weight on the lever moves the lever out of engagement with the magnet and against the force of the magnetic flux so that the lever moves out of engagement with the abutment of the one contact and permits the contacts to close.

A switch responsive to conditions which occur when a missile reaches apogee. It includes a cylinder provided with a movable weight having a cage at one end in which a conductive sphere is locked prior to launch. Some time after launch a decrease in acceleration unlocks the cage. At apogee the sphere being free of the cage is attracted by magnetism to a ring contact encircling the plunger which closes an electrical circuit.
