Abstract

A motor-vehicle seat hinge has an upper hinge element secured to the back part of the seat and a lower hinge element secured to the seat part, a positioning plate securable at any of a plurality of angularly offset positions and coacting with an abutment on the upper element to define the rest position for the seat back. An inertial two-arm pawl is pivoted on the upper hinge element and has on one arm a stop face which is engageable with the positioning plate in a blocking position of this pawl to prevent forward pivoting of the seat back. The other arm of the pawl is weighted so as normally to pivot from this blocking position into a freeing position when The back part is slowly pivoted forwardly but to resist due to its inertia the change of its position when the back part is subject to an abrupt forward movement.
