Abstract: A compact cooling system for vehicle operators includes: a variable speed compressor; a radiator coupled to the compressor with a tube; a fan adjacent to the radiator; an expansion chamber coupled to the radiator with a tube; a cooling plate coupled to the expansion chamber with a tube; a fluid reservoir coupled to the cooling plate with a tube through which cooling fluid can be transferred; and a fluid pump coupled to the fluid reservoir with a tube, the cooling plate including an inlet port for receiving warm cooling fluid from a cooling garment and an outlet port for transferring chilled cooling fluid to the cooling garment via the fluid reservoir and the fluid pump.

Abstract: A system of tethers and a helmet cooperating with the tethers for controlling a driver's head during operation of a vehicle. The system of tethers includes a pair of side tethers for attachment to the sides of the helmet and to a head and neck restraint device and either at least two rear tethers having first ends for attachment to the helmet and second ends for attachment to shoulder straps or a support member or a single rear tether having an intermediate portion attached to a support member and opposed end portions for attachment to the helmet.

Abstract: A head and neck support device for an occupant of a vehicle with a shoulder harness over the shoulders of the occupant and a helmet on a head of the occupant. The head and neck support device having a yoke, a tether, and at least one sleeve member, which has a cavity defined therethrough. The tether is configured to slide through the sleeve member cavity for a defined distance, which allows the occupant a greater range of side-to-side rotary head mobility.

Abstract: A head and neck support (HANS) device comprises a collar, a left leg unit, a right leg unit, and a leg unit rotation control assembly. The collar may be positioned behind a wearer's neck. The left leg unit may be coupled to a left side of the collar to engage the wearer's left shoulder and chest area. The right leg unit may be coupled to a right side of the collar to engage the wearer's right shoulder and chest area. The leg unit rotation control assembly may include male splines and female splines to allow the leg units to rotate with respect to the collar when the female splines are separated from the male splines and to rigidly fix the position of the leg units with respect to the collar when the female splines are interlocked with the male splines.

Abstract: A shackle is provided that is fixedly mounted to a surface. The shackle can have a body, a hasp, and a locking pin. The body can define at least one mounting bore that is configured for mounting the shackle to the surface. The proximal end of the hasp is configured to rotate relative to the body and the distal end of the hasp is configured to selectively engage the locking pin, such that an enclosed area is defined. A tethering device can be attached to the shackle via cooperative engagement with the selectively enclosed area.

Abstract: A system of tethers for controlling a driver's head during operation of a vehicle, comprising: at least two frontal straps having first ends attached to a helmet and second ends attached to shoulder straps, torso strap and/or vehicle's seat belt; at least two rear straps having first ends attached to a helmet and second ends attached to shoulder straps or the support member; and wherein the frontal and rear straps are taut during normal operation.

Abstract: A restraint device for controlling the head of a driver during a high-performance vehicle collision. The device includes a support member having a back portion and shoulder portions that extend at least partially over the shoulders of the driver; a tether for attaching the support member to the driver's helmet; and at least one anchor strap attached at one end to the support member and at the other end to the vehicle's seat belt assembly, driver's truck, and/or driver's legs, which serves to anchor the device and oppose forward and rearward movement of the driver's head during a collision event, reducing the likelihood of injury. The shoulder portions are configured to engage the vehicle's shoulder belts, which improves the restraint device's ability to resist forward movement and downward rotation of the driver's head that is caused by a collision event.
