Abstract

Medios de accionamiento lineal pirotécnico para un tensor de cinturon comprende una unidad de piston/cilindro, un generador de gas (9) para accionar el piston y la unidad de encendido (25) para activar un propulsor (13, 15) del generador de gas (9). El generador de gas (9) esta configurado como un generador de gas de etapa multiple que tiene varios propulsores (13, 15) separados uno de otro en su interior y cada uno se puede activar por separado de manera individual o al mismo tiempo.
