Description

ABSTRACT:
A trigger for a spring-type pretensioner providing pretension to a vehicle seat belt upon release of a preloaded spring comprises a first toggle and a second toggle connected to the first toggle. The first toggle is engaged with the operating end of a spring, and the second toggle is connected to an output member for transmitting sensor output. The first toggle supports the spring load while it is beyond its toggle dead point, and the second toggle engages the first toggle while it is not beyond its toggle dead point and restricts the operation of said first toggle. The second toggle receives the sensor output and upon being moved thereby beyond its dead point releases the first toggle, whereupon the spring preload is released and the pretensioner is operated.
