1. A system for securing a passenger seat to a track, the system comprising:
a fitting coupled with or forming a portion of the passenger seat, the fitting comprising a fitting body defining a fitting opening;
a shear plunger coupled with the fitting, the shear plunger comprising a shear plunger body defining a shear plunger opening and a shear plunger locking surface adjacent at least a portion of the shear plunger opening; and
a guide pin assembly comprising:
a guide pin received at least partially in the fitting opening and movable along a lift axis between a retracted state and an extended state; wherein the guide pin comprises a notch located at or adjacent a proximal segment of the guide pin; and
a locking member extending laterally from the guide pin and sized for traveling through at least the portion of the shear plunger opening in response to a movement of the guide pin from the retracted state to the extended state, wherein the locking member engages the shear plunger locking surface in response to a rotation of the guide pin in the extended state.
