Abstract

A latch assembly for releasably securing a seat assembly to a striker in an automotive vehicle. The latch assembly comprises a housing bracket, a latch link, a cinch cam and a strength cam. The latch link is pivotally coupled to the housing bracket about a first axis of rotation. The cinch cam and a strength cam are pivotally coupled to the housing bracket about a second axis of rotation. The strength cam has first, second and third cam surfaces and the cinch cam has a cinch surface. The latch link has first, second and third latch surfaces spaced between the first and second axes of rotation and a latch groove oriented away from the first and second axes of rotation. The latch link is rotatable between a latched condition engaged with the striker and an unlatched condition disengaged with the striker. The cinch surface in engaged with the first latch surface in the latched condition and the first and second cam surfaces engage with the first and second latch surfaces, respectively, when the latch link is in the latched condition and deformed under load to prevent inadvertent release of the latch assembly from the latched condition to the unlatched condition. The third cam surface engages with the third latch surface to retain the latch link in the unlatched, hold open, position.
