Abstract

The equipment automatically unlocks safety belts at a set time after an impact. It comprises a wick of set length forming a time delay after the impact and which activates an ignitre (7), before an explosion actuates a mechano pneumatic device freeing the belt. The shock load can be provided by a violent pull on the belt. The igniter comprises a spring-loaded striker, freed by movement of a catch attached to the belt.
