<p>In a safety arrangement for use in a motor vehicle, a capacitor (4, 5, 6, 7) of relatively large capacitance is provided associated with means (2, 3) to charge the capacitor. The capacitor is connected to a circuit (30, 31, 32) through which it may be discharged in order to activate a safety device. The circuit includes switch means (30, 32) adapted to complete the circuit. A further capacitor (8) of small capacitance is provided which can also be charged. The switch means (30) to close the said circuit can only be activated if the further capacitor (8) is charged.</p> |
