Abstract
Abstract An armrest lock has a pivoted latch which swings into an active locking position as a result of its own inertia, in the event of a crash, to keep the armrest locked in its raised position. The latch then engages with a projecting rib on the linkage which supports the armrest and locks movement of the linkage.
