Abstract
A latch assembly for maintaining a seat back in upright position responsive to inertial loads. Support plates include hinged upwardly extending arms defining a seat back. A latch gear includes a first plurality of exteriorly arrayed teeth. A first cam operates a second pivotal cam so that, upon rotation, the second cam rotates in an opposite direction to move into and out of contact with a pawl. The pawl is pivotally and translatably secured to the support plates and includes additional teeth arrayed opposite to the latch gear teeth and an extending end with an upwardly/arcuate shape. A wedge block defines first and second shoulder supports. In operation, the pawl engages the first support surface of the block. In response to inertial loads, the pawl shifts radially to be engaged upon the second support surface, the pawl teeth being forcibly interengaged with the latch gear teeth.
