Abstract
A neck and spine protection device comprised of a helmet for head protection, pads for shoulder protection and a fluid dampening mechanism. The fluid dampening mechanism is connected between the helmet and pads. The fluid dampening mechanism has limits at either end to limit hyper-flexion and hyper-extension injuries of the neck and spine in sudden impact situations.
Claims5
A neck and spine protection device to be worn by a person comprising:
- a helmet for head protection;
- pads for shoulder protection;
- a fluid dampening mechanism having a rod and a fluid type type cylinder including a casing with two ends, said casing having fluid therewithin, said piston being connected to said rod and movable between said ends of said casing and having at least two valves operable in opposed relation relative to each other so that fluid can flow through said piston and said valves, with one valve restricting movement of the internal piston as it approaches one end of said casing and the other valve restricting movement of the internal piston as it approaches the other end of the casing;
- a first coupling between said pads and said fluid dampening mechanism;
- and
- a second coupling between said rod and said helmet, said second coupling including a guide rail connected to said helmet having a bar extending the length of said guide rail and a first and second stop at each end of said bar;
- a bearing block having a ball at one end and a C-shaped end at another end, said C-shaped end surrounding said rod;
- bearing placed between said C-shaped end and said bars so that said C-shaped end can easily move between said first and second stops;
- and
- a locking mechanism connected to said rod having a socket and a rotating portion, said rotating portion being spring released between a locked position and an unlocked position, wherein said locking mechanism secures said ball in said socket in said locked position and allows said ball to be moved from said socket in said unlocked position.

- a helmet for head protection;
- pads for shoulder protection;
- a fluid dampening mechanism to limit hyper-flexion and hyper-extension of the neck and spine in sudden impact situations, said fluid dampening mechanisms having a first end and a second end;
- a first coupling mechanism to attach said end of said fluid dampening mechanism to said helmet, said first coupling mechanism allowing movement of the head;
- and
- a second coupling mechanism to attach said second end of said fluid dampening mechanism to said pads;
- and
- wherein said first coupling mechanism comprises a locking mechanism having a cap and a rotating portion and cap having a bore to one end and a socket in the side thereof, said rod fitting into said bore, and said rotation portion having a locked position and an unlocked position;
- a guide rail connected to said helmet said guide rail having a first stop at one end and a second stop at another end;
- bearings;
- and
- a beating block to hold said bearings against said guide rail so that said beating block moves along said guide rail between said first and second stops as the head moves, said bearing block having a ball-end that fits into said socket to attach said fluid dampening mechanism to said helmet and a C-shaped end to connect said beating block to said guide rail.
