Abstract
A door module is equipped with an inflatable bladder configured to move an interior trim panel away from the door and toward a vehicle occupant in the event of a collision. The result is reduced occupant movement, additional absorption of kinetic energy, and distribution of remaining energy over an increased surface area. The bladder can have an accordion-like configuration that unfolds when changing from a deflated state to an inflated state, and more than one bladder can be used to control which portions of the trim panel move relative to each other.
