Abstract: A motorsports safety harness assembly includes a restraint device for securing the head and neck against frontal impact injuries, and allows for facilitated removal in exigent circumstances or with limited mobility such from a damaged automobile. A pair of detachable wings engages a front upper torso or chest region of a wearer, and couples to a rigid headpiece extending behind the skull region for attachment to a helmet for restraining the head and neck from sudden forceful movement commonly associated with basal skull fractures and other impact injuries. The wings and headpiece secure snugly around the neck of the wearer for providing support against frontal impact, while the wings separate from the headpiece via a detachable coupling and release control to allow the wearer to exit the vehicle. The coupling provides rigid support against impact, and employs a wearer activated release to permit rapid uncoupling in exigent crash situations.
