An air bag inflator (20) includes gas stored at or above a predetermined pressure in a chamber (24) in a container (22). An initiator (10) connected with the container (22) is exposed to the pressure of the gas stored in the chamber (24). A closure can (120) of the initiator (10) includes an electrically conductive sensor portion (140) which is spaced apart from an electrically conductive contact can (200) when the pressure in the chamber (24) is at or above the predetermined pressure. If the pressure in the chamber (24) drops below the predetermined pressure, the sensor portion (140) moves into electrical contact with the contact can (200). The engagement of the sensor portion (140) with the contact can (200) completes an electrical circuit to provide an indication of low pressure in the inflator (20).
Cette invention concerne un gonfleur (20) de sac de protection active qui fait appel à un gaz stocké à une pression minimum prédéterminée dans une enceinte (24) d'un contenant (22). Un initiateur (10) raccordé au contenant (22) est exposé à la pression du gaz stocké dans l'enceinte (24). Un godet de fermeture (12) de l'initiateur (10) comporte une partie détectrice conductrice d'électricité (140) qui est espacée d'une pastille de contact conductrice (200) lorsque la pression dans l'enceinte est au moins à la valeur minimum requise. Lorsque la pression dans l'enceinte (24) baisse sous cette valeur, la partie (140) se met en contact avec la pastille (200) et ferme un circuit électrique de transmission d'un signal de basse pression au gonfleur (20).
