seat hinge pin retainers?

Wrapping up the loose ends. Thought I would have come up with the trick way of retaining those hinge pins by now. Haven't found what I consider the ideal way.

I would like a tool free retaining method. Cockpit maintenance is way easier with seat backs out of the way.

Someone got a cool design?

Put a slight bend in the center of the pin.

Friction will do the work for you

Hinge pin

On both the pilot and passenger seats (8 ) the pins go in from the center of the hinge . A simple 90* 3/4 to 1" bend as a handle, the seat cushion will hold it down .

No retainer needed

They will stay in place. Definitely don't put a bend in them, they are hard enough to get out when straight after a couple years.
