Abstract: The invention relates to a pyrotechnically releasable mechanical linking device between a first and second mechanical element, said first and second elements likely to be subjected to tensile and/or compressive force along an axis, said device comprising at least one pyrotechnic component and at least one locking means linking the two mechanical elements along at least one axis, said locking means able to be released when the mechanical elements are subjected to tensile and/or compressive forces along said axis and that is held in its locking position by retention means that are released by the pressure of gases generated by igniting the pyrotechnic component, device wherein the retention means comprise a cap integral with a head carrying the pyrotechnic component or else forming a head in itself carrying the pyrotechnic component.

Abstract: The invention concerns a device for the embrittlement of a motor vehicle pedal pivot pin, characterized in that the pin comprises at least a starting point of fracture and reinforcing means arranged at the starting point of fracture for increasing the pin resistance, the reinforcing means being capable of moving by action of motoring means to be positioned at some distance from the starting point of fracture thereby ensuring that the pin is embrittled.

Abstract: A pyrotechnic igniter for adaptation to a specific gas generator or pyromechanism, the igniter including at least one pyrotechnic composition located inside a cartridge composed of a case extended by at least two pins. The cartridge is located in a casing including at least an upper shell joined to a lower shell, the upper shell containing the cartridge and the lower shell having at least two protruding electrodes internally connected an internal circuit and to the pins.
