1. A multi-actuator capable vehicle headrest comprising:
a first seat back support;
a second seat back support spaced from the first seat back support;
a headrest support extending between the first seat back support and the second seat back support;
a multi-cam release mechanism mounted to the headrest support, the multi-cam release mechanism including a first cam and a second cam;
a biasing element connected to the headrest support, the biasing element including a first cam surface that is engaged by the first cam and a second cam surface that is engaged by the second cam to selectively retain the multi-actuator capable vehicle headrest in the deployed configuration;
a headrest shell member pivotally mounted to the headrest support through the multi-cam release mechanism; and
an actuator rotatably mounted to the headrest shell member, the actuator including a first actuator portion operable to disengage the multi-cam release mechanism based on a first input and a second actuator portion operable to disengage the multi-cam release mechanism based on a second input that is distinct from the first input allowing the multi-actuator capable vehicle headrest to transition between a deployed configuration and a folded configuration.
