Abstract

A jockey jacket actuates upon sensing a particular event, such as the jockey falling from the horse during a race. A series of air tracks are inflated by a gas generator to pump up a series of air-pockets, mini-airbags, and a collar protection region, preferably with a series of concentric circular cylinders which expand and provide resistance to motions that are transverse to the concentric axis. A plurality of caps are telescopically disposed within the tracks and are forced upwards by the injected gas. These caps form a column that, together with the other columns and a support member Within the jacket collar, forms an exoskeleton around the jockey'"'"'s neck. A base webbing provides support for the columns. The jacket includes microelectronics to control the jacket actuation. The jacket is usable for other activities, such as motorcycling.

Claims

1. A jacket for protecting a wearer from injury during a fall from a vehicle, comprising:

at least one layer forming a jacket;

a plurality of airpockets woven into the jacket, each of the airpockets being in fluid communication with other airpockets and being expandable in response to increased pressurization;

a gas generator for pressurizing the airpockets, and one or more pressurization tubes to communicate gas between the gas generator and the airpockets;

regulator means for controlling gas flow between the gas generator and the airpockets, the regulator means being responsive to a signal generated when the wearer of the jacket falls from the vehicle;

pressure sensing means for sensing pressure within at least one of the airpockets and for generating a pressure signal representative of the pressure; and

pressure regulation means, including microprocessor means, connected to the pressure sensing means for controlling pressurization within the airpockets by controlling the flow of gas into or out of the airpockets in response to the pressure signal.

2. A jacket according to claim 1, wherein the vehicle is selected from the group consisting essentially of a horse, a motorcycle, a snowmobile, a bobsled, and a bicycle.

3. A jacket according to claim 1, further comprising a plurality of mini-airbags sewn within the jacket and connected to the gas generator by a plurality of gas conduits, the mini-airbags being responsive to increased pressurization to provide cushioning within the jacket, and wherein the regulator means further comprises means for controlling gas flow from the gas generator through the conduits and to the mini-airbags.

4. A jacket according to claim 1, wherein the jacket has a collar portion and further comprising one or more circular cylinders connected to the collar portion, the cylinders being connected to the gas generator by one or more pressurization tubes, the cylinders being expandable in response to increased pressurization to substantially surround the wearer'"'"'s neck to create a resistance against sideways movement of the wearer'"'"'s head.

5. A jacket according to claim 1, wherein the pressure regulation means comprises valve means for releasing pressure from the airpockets in response to signals generated by the microprocessor means.

6. A jacket according to claim 1, wherein the pressure regulation means comprises valve means, connected to a gas generator, for injecting air into the airpockets in response to signals generated by the microprocessor means.

7. A jacket according to claims 1, wherein the pressure regulation means further comprises means for controlling the pressurization within the airpockets according to a non-linear function of pressure and time.

8. A jacket according to claim 1, wherein the jacket has a collar portion, and further comprising:

a base webbing woven within the jacket, the webbing extending circumferentially about the jacket and in a horizontal position relative to a normal upward posture of a wearer of the jacket;

a collar structure within the collar region of the jacket, the collar structure being substantially rigid and extending circumferentially about the collar region such that the collar structure surrounds at least part of the neck of a wearer of the jacket;

a plurality of tracks, woven within the jacket and arranged substantially vertically between a base of the jacket and the collar portion; and

a plurality of caps within each of the tracks, the caps formed of a sturdy material and being responsive to pressurization within the tracks to accelerate towards the neck, the lower-most cap connecting to the base webbing once the lower-most cap accelerates past the base webbing, the caps forming a substantially rigid column, thereby forming an exo-skeleton about the neck and protecting the neck during the fall.

9. A jacket according to claim 8, further comprising a upper-most cap within each of the tracks, the upper-most cap being connected to the collar structure to provide a connection point to facilitate column formation.

10. A jacket according to claim 8, further comprising a web access to remove the base webbing from the jacket selectively.

11. A jacket according to claim 8, further comprising a blocking element within one or more caps, the blocking element preventing adjacent and lower caps from engaging and connecting with adjacent and upper caps.

12. A jacket according to claim 8, further comprising a helmet and at least two straps connected to the helmet, each of the straps connected with one of the tracks such that the column connects substantially into the helmet.

13. A jacket according to claim 1, wherein the jacket has a collar portion and further comprising a plurality of circular cylinders connected to the collar portion, each of the cylinders having a different radial size, the cylinders being arranged sequentially according to radial size, with smaller radial cylinders on top of larger radial cylinders, the cylinders being connected to the gas generator by the pressurization tubes, the cylinders being arranged expandable in response to increased pressurization to substantially surround the wearer'"'"'s neck to create a resistance against sideways movement of the wearer'"'"'s head.

14. A jacket according to claim 1, wherein the jacket material forms a vest-like jacket.

15. A jacket according to claim 1, wherein the jacket material forms a jump-suit jacket, the jump suit jacket having one or more airpockets surrounding a buttocks region of the jacket, thereby protecting a wearer of the jacket against compression injury.

16. A jacket according to claim 1, wherein the layer are formed of material selected from the group consisting essentially of ballistic nylon, polyurethane, rubber with cloth covers, vinyl and textiles that are heat sealed and sewn, steel reinforced aramid neoprene with aramid fiber reinforcement, polyethylene, polypropylene, polyester, and acetate.

17. A jacket according to claim 1, further comprising means for releasing gas from the jacket after about five seconds after pressurization.

18. A jacket according to claim 1, wherein the regulator means comprises:

a proximity sensor for providing information about the wearer'"'"'s position relative to the vehicle;

a microprocessor connected to the actuation sensor, and further connected to a logic section, the logic section providing logic flow for determining when to actuate the gas generator based upon information from an actuation sensor;

the microprocessor generating the signal in response to the logic flow from the logic section.

19. A jacket according to claim 18, wherein the proximity sensor is selected from the group consisting essentially of a tether, a pressure sensor, a capacitive sensor, and an accelerometer.

20. A jacket according to claim 18, further comprising switch means, connected to the microprocessor, for turning the microprocessor on and off.

21. A jacket according to claim 18, wherein the regulator means further comprises a radio-frequency receiver, wherein the receiver is responsive to radiowaves generated nearby to the jacket to activate the regulator means such that the regulator means is responsive to the signal.
