The patent was originally filed in October 2020, not long after the debut of the Bronco with its removable doors. The vehicle used for the patent images doesn't resemble the Bronco, but theoretically Ford could launch a Jeep Wrangler competitor clearly in mind with this idea. In short, it's a network of screens that can deploy either automatically or at the driver's command. Motors move the screens into position, and it's not just for doors. The patent also mentions screens for removable roof panels.
Screens over open doors can certainly provide a bit more safety for drivers and passengers afraid of falling out, but Ford also hints at a larger safety aspect with the patent. The screens are extended and retracted by electric motors, but a pyrotechnic device could also be used to literally blow them into place if an impact event is detected. Presumably, sensors would confirm that no arms, legs, or fingers are in the openings before igniting. And it's not clear how quickly they would need to deploy to be effective.
We can't wait to see this feature on future vehicles! As always, many patents are filed just to protect ideas that never come to fruition. That said, deployable screens seem like a great idea for door cavities.
