Abstract:
A latch assembly is suitable for a ramp assembly, the ramp assembly having a ramp portion coupled to a fixed portion so that the ramp portion reciprocates between a stowed position and a deployed position. The latch assembly includes a latch pin attached to the ramp portion. The latch assembly further includes a latch fitting coupled to the fixed portion of the ramp assembly. The latch fitting has a hook portion and a tang. The latch fitting selectively reciprocates between a first position, a second position, and a third position. In the first position, the hook engages the latch pin to retain the ramp portion in the stowed position. In the second position, the hook portion is disengaged from the latch pin. In the third position, the tang applies a lifting force to the ramp portion.
