Abstract: An aircraft passenger seat having a dynamic breakover assembly includes a seat bottom frame and a seat back pivotally-mounted to the seat bottom frame that allows the angle of the seat back relative to the seat bottom frame to be varied from an upright taxi takeoff and landing (TTOL) position to a reclined position. The seat may include a means for sensing acceleration corresponding to a force indicative of an abnormal event; and a breakover mechanism coupled to the seat bottom frame and the seat back in which the means for sensing acceleration is coupled to the breakover mechanism. The breakover mechanism can prevent movement of the seat back in a forward direction past the TTOL position during normal use, and permit forward movement of at least a portion of the seat back in the forward direction past the TTOL position upon activation by the means for sensing acceleration.

Abstract: A passenger seat, having a seat back, and a seat bottom, including a seat pan, supported by a frame mounted on laterally spaced-apart legs for being mounted to the deck of the aircraft by track fittings. A seat back frame assembly and a seat bottom assembly are joined for articulating movement such that when the seat back is reclined, the seat pan is shifted forward and the forward end of the seat pan and thus the seat bottom is raised in order to maintain an appropriate passenger seating angle.
