Abstract
A passenger compartment mounted sensor senses crashes when located outside of the crush zone in response to velocity changes. The velocity change needed to fire the sensor is much greater than the velocity change associated with overcoming the sensor bias.
Claims15
A mechanical sensor with a low bias for mounting within a vehicle passenger compartment operable without electrical power for igniting the pyrotechnic element of an air bag safety restraint system for the vehicle, said sensor comprising a sensor train which includes:
- a primer;
- a spring biased firing pin;
- a means responsive to sustained acceleration above the bias for releasing the firing pin to strike the primer.
