Abstract

LA INVENCION SE REFIERE A UN MECANISMO DE ENCENDIDO PARA UN GENERADOR (18) DE GAS PIROTECNICO DE UN SISTEMA DE RESPALDO DE OCUPANTES PARA UN VEHICULO, DONDE EL ELEMENTO (26) DE PERCUSION PARA AL DISPARO DEL PROCESO ESTA SUJETO PREVIAMENTE AL MENOS CON UN RESORTE (56) DE TAL MODO, QUE EL RESORTE (56) DEL ELEMENTO (26) DE PERCUSION SE CARGA EN UNA PRIMERA DIRECCION CONTRA UN TOPE. ADEMAS EL RESORTE (56) EFECTUA EL MOVIMIENTO DEL ELEMENTO (26) DE PERCUSION EN UNA SEGUNDA DIRECCION BASADO EN LA FUERZA DE INERCIA ACTIVA EN UNA ACELERACION DEL VEHICULO CON UNA FUERZA EN OPOSICION QUE CRECE HASTA CONSEGUIR UN PUNTO MUERTO. DE AQUI SE GENERA QUE EL RESORTE (56) SE TRANSFORME EN UN MOMENTO DE GIRO, CON LA GENERACION DE LA FUERZA AXIAL QUE A TRAVES DE UN DISPOSITIVO (58) DE TRANSFORMACION IMPULSA EL ELEMENTO (26) DE PERCUSION.
