Abstract
A passenger seat is with a seat back breakover assembly for preventing movement of the seat back unit forwardly past an upright position during normal use and for permitting forward movement of the seat back past an upright position in response to a predetermined abnormal load applied in a forward direction. The breakover assembly includes a controlled deformation member having a bend in one end thereof and positioned intermediate one a section assembly module of the seat and the seat back unit. The bend of the deformation member captures therein an attachment member fixed to and movable forwardly and rearwardly in unison with the seat back unit. An end of the deformation member remote from the bend is restrained for restricted and controlled movement relative to the section assembly module. The deformation member has a resistance to deformation in response to a normal forwardly-applied force sufficient to prevent forward movement of the seat back unit beyond the upright position. The deformation member is deformable in response to an abnormal forwardly-applied force along its length whereby the bend in the deformation member is translated rearwardly along the length of the deforma…
