Patient transport system including a patient transport apparatus and loading system for the same

A patient transport system comprising:

• a patient transport apparatus operable by a user for transporting a patient along stairs, the patient transport apparatus including:
• a support structure,
• a seat section coupled to the support structure for supporting the patient, and
• a track assembly having a movable belt, the track assembly being operatively attached to the support structure and arranged for selective operation between a retracted position disposed adjacent to the support structure and a deployed position extending to engage stairs;
• and
• a loading system for loading and unloading the patient transport apparatus from a cargo area of a vehicle, the loading system including:
• a brace defining a mounting axis, the brace configured to be mounted to the cargo area of the vehicle,
• a first arm supported for rotation relative to the mounting axis between a stowed state and a deployed state,
• a second arm coupled to the first arm for pivotal movement relative to the first arm,
• a receptacle coupled to the second arm, the receptacle configured to receive and support the patient transport apparatus for movement relative to the cargo area of the vehicle as the first arm moves between the stowed state and the deployed state, and
• a ratchet assembly interposed between the brace and the first arm to selectively permit motion of the first arm between the stowed state and the deployed state.
