Head restraint device having a spacer for use with a high-performance vehicle
View Patent ↗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.
1. A restraint device for controlling a driver's head during a vehicle collision, comprising:
a spacer;
a tether attached to said spacer and adapted for being attached to a helmet;
a strap attached to said tether and adapted for being attached to a vehicle's seat belt assembly;
wherein the seat belt assembly serves as an anchor to control movement of the driver's head during a vehicle collision when said strap is attached to the seat belt assembly; and
wherein at least a portion of said strap is positioned between the driver's legs when the restraint device is in place on the driver.
2. The restraint device in accordance with claim 1 wherein tension forces applied to said tether are directly transferred to said strap.
3. A restraint device for controlling a driver's head during a vehicle collision, comprising:
a spacer;
a tether attached to said spacer and adapted for being attached to a helmet;
a strap attached to said tether and adapted for being attached to a vehicle's seat belt assembly;
wherein the seat belt assembly serves as an anchor to control movement of the driver's head during a vehicle collision when said strap is attached to the seat belt assembly;
wherein the seat belt assembly includes a coupling means and said strap is adapted to be attached at said coupling means; and
wherein said coupling means is a cam lock.
4. A restraint device for controlling a driver's head during a vehicle collision, comprising:
a spacer;
a tether attached to said spacer and adapted for being attached to a helmet;
a strap attached to said tether and adapted for being attached to a vehicle's seat belt assembly;
wherein the seat belt assembly serves as an anchor to control movement of the driver's head during a vehicle collision when said strap is attached to the seat belt assembly;
wherein the seat belt assembly includes a coupling means and said strap is adapted to be attached at said coupling means; and
wherein the driver is freed from being secured to the vehicle by uncoupling said coupling means.
5. A restraint device for controlling a driver's head during a vehicle collision, comprising:
a spacer;
a tether attached to said spacer and adapted for being attached to a helmet;
a strap attached to said tether and adapted for being attached to a vehicle's seat belt assembly;
wherein the seat belt assembly serves as an anchor to control movement of the driver's head during a vehicle collision when said strap is attached to the seat belt assembly; and
wherein the seat belt assembly includes a lap belt and said strap is adapted to be attached to the seat belt assembly by the lap belt.
6. The restraint device in accordance with claim 5 wherein said restraint device and the driver are freed from being secured to the vehicle by uncoupling the lap belt.
7. The restraint device in accordance with claim 1 wherein the seat belt assembly includes a shoulder belt and said strap is adapted to be attached to the seat belt assembly by the shoulder belt.
8. The restraint device in accordance with claim 7 wherein said restraint device and the driver are freed from being secured to the vehicle by uncoupling the shoulder belt.
9. The restraint device in accordance with claim 3 wherein said restraint device and the driver are freed from being secured to the vehicle by releasing said strap from said cam lock and wherein said driver may egress from the vehicle while said restraint device is attached to and being carried on the driver.
10. A restraint device for controlling a driver's head during a vehicle collision, comprising:
a spacer;
a tether attached to said spacer and adapted for being attached to a helmet;
a strap attached to said tether and adapted for being attached to a part of the driver's body;
wherein tension forces applied to said tether are directly transferred to said strap;
wherein the driver's body serves as an anchor to control movement of the driver's head during a vehicle collision when said device is being worn by the driver; and
wherein the part of the driver's body to which said strap is attached and which serves as an anchor is the driver's legs.
11. The restraint device in accordance with claim 10 wherein said restraint device is not attached to a vehicle's seat belt assembly and wherein the driver and the restraint device are freed from being secured to the vehicle by uncoupling the seat belt assembly.
12. The restraint device in accordance with claim 10 wherein said restraint device is attached only to the driver's body and helmet.
13. The restraint device in accordance with claim 10 wherein said restraint device is adapted for being attached to a vehicle's seat belt assembly by said strap, wherein the seat belt assembly anchors the driver's head to control movement of the driver's head during a vehicle collision when said strap is attached to the seat belt assembly, and wherein the driver and the restraint device are freed from being secured to the vehicle by uncoupling the seat belt assembly.
