Abstract
An inertial latch assembly including a planar shaped sector pivotally mounted between a pair of spaced apart support plates. The sector exhibits a bottom including a central projecting shoulder separating first and second bottom surfaces. An arcuate interior channel in the sector is offset from its pivotal mounting location, a pin extending through a second channel defined in a selected support plate and seating within the arcuate channel so that the pin exerts a bias against the sector during travel along the arcuate interior channel. A pendulum is secured in sandwiching fashion between the support plates and proximate the bottom extending surface of the planar shaped sector, an arcuate edge thereof seating against a selected bottom extending surfaces of the rotatable sector, depending upon a pivoted position established between the sector and the support plates. The pendulum responds to an inertial impact condition by engaging against the underside shoulder of the sector and to prevent rotation of the sector relative to the support plates.
