Rumble Seat Risk

[Huskerj]

I just bought a Model A Coup. We spent some time re-aligning the rumble seat and replacing the bushings. The seat now opens and closes very easily. The primary use of the rumble seat will be to haul grandkids around.

My question: Is there a risk that the rumble seat will close on sudden braking? If so, does anyone have suggestions on preventing the seat from closing?

Thanks in advance for any response.
