Abstract
An inflatable tunnel reinforcement for reinforcing a vehicle tunnel structure includes a first wall, a second wall, and at least one fold connecting the first and second walls. The inflatable tunnel reinforcement further includes an inflator adapted to increase a gas pressure between the first and second walls. In an inflated configuration, the inflatable tunnel reinforcement forms a continuous load path between interior walls of the tunnel structure generally orthogonal to a longitudinal axis of the tunnel structure.
