1. An energy absorbing headrest for a vehicle comprising:
a base member;
a frame pivotally mounted to the base member;
a biasing member mounted between the base member and the frame, the biasing member providing a biasing force to the frame;
a travel limiter formed from a resilient material mounted to the base, the travel limiter constraining motion of the frame provided by the biasing force;
a release mechanism mounted to the base member and retaining the frame against the biasing force, the release mechanism selectively releasing the frame upon receipt of a release signal; and
a controller operatively connected to the release mechanism, the controller being operable to issue the release signal in response to detecting an external force on the vehicle.
