Abstract
Inertial igniters for initiating a thermal battery and methods of preventing initiation of an inertial igniter are provided. The method including: biasing a mass element from a base element with a spring element connecting the mass element and the spring element; and removably disposing a safety member between the mass element and the base element to prevent relative movement between the mass element and base element to prevent accidental initiation of the inertial igniter. The method can further comprise removing the safety member prior to subjecting the inertial igniter to all-fire conditions.
Claims13
An inertial igniter comprising:
- a mass element;
- a base element;
- a spring element connecting the mass element and the base element;
- and
- a safety member removably disposed between the mass element and the base element for preventing relative movement between mass element and base element to prevent accidental initiation of the inertial igniter.
