Deployable reinforcement for vehicle door
A vehicle-door reinforcement includes a first beam elongated along an axis between a first end and a second end. The vehicle-door reinforcement includes a hinged beam elongated along the axis. The hinged beam includes a first segment and a second segment hinged to each other. The first segment is engaged with the first beam and the second segment is slideably engaged with the first beam. The vehicle-door reinforcement includes an actuator fixed to the first beam and connected to the second segment.
1. A vehicle door, comprising:
a door panel;
