Propelling charge element for gas generator of safety device in vehicle, has core, which is made of pyrotechnic material and is partially surrounded with sleeve made of material retarding burning of core, where sleeve is pressed on core

摘要

The propelling charge element (10) has a core (12), which is made of pyrotechnic material. The core is partially surrounded with a sleeve (14), which consists of a material retarding the burning of the core. The sleeve is pressed on the core. The material is selected from the group consisting of bristles, boron oxides, calcium carbonate, aluminates, aluminum oxides, molecular sieves, silicates, silicon dioxide and Sodium silicates and mixtures of these materials. An independent claim is included for a method for manufacturing a propelling charge element.
