Abstract

Arrastre lineal para tensor de cinturón de seguridad. El arrastre lineal para un tensor de cinturón de seguridad de vehículo tiene una carga pirotécnica que, al encenderse, emite una gas bajo presión al interior (24) del pistón (22). El lado interno de la pared de extremo (33) de tubo de cilindro (20), para el pistón (22), tiene un cojín (44) formado por una longitud de hilo. El pistón (22) tiene una abertura de paso en el extremo axial hacia la pared de extremo (34) del tubo de pistón (20), cubierto sobre el lado interno por un disco de seguridad.
