An inflatable pressure structure includes an airtight flexible membrane having collapsed and inflated configurations. The inflatable pressure structure includes an elongated pressure-assisted seal that is configured to selectively seal an opening in the airtight flexible membrane. The pressure-assisted seal includes first and second seal components that sealingly engage one another and prevent escape of gas from inside the airtight flexible membrane. The airtight flexible membrane, when inflated, generates a force transverse to the pressure-assisted seal tending to pull the first and second seal components apart. Pressurized gas inside the airtight flexible membrane causes the first and second seal components to more securely engage one another whereby a force transverse to the pressure-assisted seal does not disengage the first and second seal components.
