Abstract

An improved head and neck support device (10) for occupants (100) of high performance vehicles, is described. The device includes a restraining yoke (12) and a collar (11). The restraining yoke has two front portions (12A and 12B) which extend down from the shoulders (102) of the occupant along the torso (104) of the occupant. The restraining yoke also includes a rear portion (12C) which extends behind the neck (106) and the shoulders of the occupant. The collar of the device extends upward from the rear portion of the restraining yoke behind the head (112) of the occupant. The collar of the device is connected by tethers (15 or 215) to the helmet (108) of the occupant. The shoulder belts (110A) of the shoulder harness (110) of the vehicle extend over the front portions and rear portion of the restraining yoke when the device is mounted on the occupant such that the device is between the shoulder belts and the occupant. The collar acts to transfer the forces from the helmet through the tethers to the collar of the restraining yoke which transfers the forces to the shoulder harness thereby reducing the forces being transmitted to the neck of the occupant.

Claims

1. A head and neck support device for an occupant of a vehicle with a shoulder harness over shoulders of the occupant and a helmet on a head of the occupant and with a horizontal level center of gravity of the head and helmet combined at about eye level of the occupant, which comprises:

(a) a stiff restraining means including front portions and a rear portion relative to the occupant, the front portions contoured to fit a torso and shoulders of the occupant and the rear portion contoured to fit behind a neck and the shoulders of the occupant, the front and rear portions having load bearing surfaces on a side opposite the occupant wherein shoulder belts of the shoulder harness are in contact with the load bearing surfaces of the front and rear portions of the stiff restraining means when the occupant is secured in the vehicle;

(b) a stiff high collar mounted on the restraining means which extends upward from the rear portion of the restraining means to at least adjacent the horizontal level center of gravity of the head and helmet combined and adjacent the neck of the occupant which allows movement of the head to provide forward and lateral fields of view for the occupant; and

(c) tethering means attached between the collar and the helmet wherein the tethering means provides a restraint between the helmet and the collar which is in a substantially horizontal plane and wherein during normal vehicle operation or in a crash, the collar transmits forces to the restraining means from the tethering means and the load bearing surfaces of the restraining means transmit forces from the restraining means to the shoulder belts of the shoulder harness to allow the shoulder harness to provide resistance to the tethering means through the restraining means and collar thereby reducing the motions of the head relative to the torso and forces being transmitted to the neck of the occupant which may cause fatigue and injury in vehicle operation or in a crash.

2. The head and neck support device of claim 1 wherein the front and rear portions of the restraining means have channels which form the load bearing surfaces and accommodate the shoulder belts of the shoulder harness.

3. The head and neck support device of claim 2 wherein the channels have an inner lip which prevents the shoulder belts of the shoulder harness from moving inward toward the neck of the occupant.

4. The head and neck support device of claim 1 wherein in normal vehicle operation, the collar is spaced apart from the helmet of the occupant.

5. The head and neck support device of claim 1 wherein the restraining means and the collar are an integral piece.

6. The head and neck support device of claim 1 wherein the tethering means is attached between the collar and the helmet adjacent the horizontal level center of gravity of the head and helmet combined.

7. The head and neck support device of claim 1 wherein the tethering means is two straps connected to opposite sides of the collar adjacent each shoulder of the occupant.

8. The head and neck support device of claim 7 wherein the straps are of such a length as to allow side to side turning movement of the head of the occupant.

9. The head and neck support device of claim 7 wherein the straps extend through openings in the helmet along an outside of the helmet and an outside surface of the collar and in through a first opening in the collar and along an inside surface of the collar and back through a second opening in the collar.

10. The head and neck support device of claim 9 wherein a first end of the straps has an enlarged portion which prevents the first end of the straps from moving through the openings in the helmet.

11. The head and neck support device of claim 1 wherein the rear portion has a thickness such that a bottom of the rear portion contacts a back of the occupant adjacent the shoulders and a top of the rear portion having the load bearing surfaces is spaced above the shoulders of the occupant.

12. The head and neck support device of claim 11 wherein the rear portion of the restraining means is hollow such as to reduce the weight of the device.

13. The head and neck support device of claim 1 wherein the load bearing surface of the rear portion is positioned such that the shoulder belts of the shoulder harness on the load bearing surfaces of the rear portion are substantially parallel with the horizontal level of a top of the shoulders of the occupant.

14. The head and neck support device of claim 1 wherein an inner side of the rear portion has a notch to accommodate a neck of the occupant.

15. The head and neck support device of claim 1 wherein the load bearing surfaces are provided with a friction material which increases frictional forces between the load bearing surfaces and the shoulder belts.

16. The head and neck support device of claim 1 wherein there are two front portions which extend from the rear portion down a front of the torso of the occupant on each side of the neck.

17. A method for providing neck protection for an occupant of a vehicle, the vehicle having a shoulder harness with shoulder belts for securing the occupant into the vehicle, which comprises:

(a) providing a helmet for a head of the occupant;

(b) providing a head and neck support device having a stiff restraining means including front portions and a rear portion relative to the occupant, the front portions contoured to fit a torso and shoulders of the occupant and the rear portion contoured to fit behind a neck and shoulders of the occupant, the front and rear portions having load bearing surfaces on a side opposite the torso of the occupant;

a stiff high collar mounted on the restraining means which extends upward from the rear portion of the restraining means to at least adjacent a horizontal level center of gravity of the head and helmet combined and adjacent the neck of the occupant; and

tethering means attached between the collar and the helmet;

(c) positioning the neck support device on the shoulders of the occupant such that the front portions of the restraining means are adjacent the torso of the occupant and the rear portion of the restraining means is adjacent the neck and shoulders of the occupant;

(d) positioning the helmet on the head of the occupant;

(e) attaching the tethering means between the collar of the neck support device and the helmet, wherein the tethering means provides a restraint between the helmet and the collar which is in a substantially horizontal plane; and

(f) securing the shoulder harness around the occupant such that the shoulder belts of the shoulder harness are adjacent and in contact with the load bearing surfaces of the front and rear portions of the restraining means of the neck support device, wherein during normal vehicle operation or in a crash, the collar transmits forces to the restraining means from the tethering means and the load bearing surfaces of the restraining means transmit forces from the restraining means to the shoulder belts of the shoulder harness to allow the shoulder harness to provide resistance to the tethering means through the restraining means and collar thereby reducing the motions of the head relative to the torso and forces being transmitted to the neck of the occupant which may cause fatigue and injury in vehicle operation or in a crash.
