1. An improvement in an aerodynamic fairing assembly for a tractor-trailer having a panel housing and an inflatable panel mounted to the panel housing where the inflatable panel inflates to extend from the panel housing to a deployed position and deflates to retract into the panel housing in a stowed position,
the improvement comprises the panel housing including a gate and a spring hinge pivotally connecting the gate to the panel housing for movement between an open orientation when the inflatable panel extends from the panel housing and a closed position when the inflatable panel is retracted into the panel housing, the spring hinge having a pair of axially aligned coils, an integral neck part connected between the pair of coils and affixed to the gate, and a pair of integral end arms each extending from the one of the pair of coils and affixed to the panel housing. |
