Abstract: A restraint device for controlling the head of a driver during a high-performance vehicle collision. The device includes a rigid spacer positioned along the back of the driver, a tether for attaching the spacer to the driver's helmet, and an anchor strap attached at one end to the tether and at the other end to the vehicle's seat belt assembly and/or the driver's legs which serve as an anchor, opposing forward and downward movement of the driver's head during a frontal collision to reduce the likelihood of injury to the driver. During a frontal collision, deceleration forces applied to the driver's head cause the tether and anchor strap to be tensioned. As such, forces are directly transferred through the tether to the anchor strap and, ultimately, to the anchor in order to resist forward movement and downward rotation of the driver's head.

Abstract: A restraint device for controlling the head of a driver during a high-performance vehicle collision. The device includes a rigid member positioned along the back of the driver, a tether for attaching the member to the driver's helmet, and a strap for anchoring the device. The vehicle's seat belt assembly or the driver's own body, such as his torso, waist or legs, may be used to anchor the device. During a vehicle collision, forces from the head are transferred through the device (i.e. tether, rigid member, and strap) into the anchor in order to resist forward movement and downward rotation of the driver's head.
