Abstract
An improved inertially locking hinge for vehicular seats which permits the seat back to be pivoted downwardly when the vehicle is not subjected to inertial forces but which, under the influence of selected inertial forces, causes a simple metal block element to pivot into engagement with ratchet teeth on the movable of the hinge elements. Weight and space savings are achieved by using a small thrust carrying block element secured in a plastic case and the case is pivotal in a slightly arcuate opening and the case enclosing a mass positioned to act between parallel spaced-apart fixed plates, the plates pivotally supporting the principal hinge point and seat back support. The block element carries the thrust of the teeth into the fixed plates at a buttress at the arcuate opening.
