Abstract

Un accelerometro per rilevare variazioni di velocità, particolarmente adatto per sistemi di sicurezza a trattenuta per passeggeri in un autoveicolo per l'apertura di un cuscino d'aria, comprende un involucro con lame di contatto e un elemento di contatto sollecitato magneticamente. L'elemento di contatto è disposto per spostarsi verso le lame di contatto quando viene rilevata una decelerazione che supera un livello di soglia. Un magnete permanente cilindrico viene utilizzato per sollecitare l'elemento di contatto.
