Amazon has won a patent to create an airbag system for cell phones and tablets.

Engadget reports the U.S. Patent and Trademark Office officially granted the patent Tuesday to Amazon CEO Jeff Bezos and Vice President Greg Hart, but it could be years down the road before you actually see it in use.

The patent application claims the device would be A method for protecting a portable device that includes an airbag deployable from a side of the portable device, comprising: detecting that the portable device will impact a surface; prior to impact with the surface, determining if a risk of damage to the portable device from the impact exceeds a damage threshold; when the risk of damage to the portable device exceeds the damage threshold: altering the orientation of the portable device such that the air bag first impacts the surface; and deploying the airbag prior to impact with the surface.
