- 5. The shock absorbing athletic equipment of claim 1, wherein said means for placing said cavity within said enclosure in limited communication with the exterior of said enclosure comprises at least one valve allowing the exit of air from said cavity and wherein said body portion further comprises at least one valve allowing the inlet of air to said cavity from said exterior of said enclosure.
- 6. The shock absorbing athletic equipment of claim 1, wherein said body portion foam core comprises a multilayered laminate of open-celled foam material.
- 7. The shock absorbing athletic equipment of claim 1, wherein a surface of said foam core is at least partially bonded to an adjacent internal surface of said enclosure.
- 8. The shock absorbing athletic equipment of claim 1, wherein said insert comprises a flexible enclosure defining an internal cavity said flexible enclosure being at least generally impermeable to air.
- 9. The shock absorbing athletic equipment of claim 8, wherein said insert further comprises a foam core contained within said insert cavity.
- 10. The apparatus of claim 9, wherein said insert foam core is formed of open-celled foam material.
- 11. The shock absorbing athletic equipment of claim 9, further comprising means for placing said cavity in limited fluid communication with the exterior of said insert enclosure.
- 12. The shock absorbing athletic equipment of claim 9, wherein said insert foam core is formed of closed-cell foam material.
- 13. The shock absorbing athletic equipment of claim 8, wherein said insert further comprises means for inflating said enclosure to a pressure greater than one atmosphere.
- 14. The shock absorbing athletic equipment of claim 1, further comprising a shield structure adapted to distribute said impacting force over at least a portion of said shock absorbing body portion.
- 15. The shock absorbing athletic equipment of claim 14, wherein said first and second surfaces of said body portion foam core are at least partially bonded to adjacent surfaces of said fabric enclosure around said foam core.
- 16. Shock absorbing athletic equipment for protecting a wearer's body from an externally impacting force, comprising:
- a shock absorbing body portion adapted to generally conform to said wearer's body and to generally make contact therewith except at at least one selected area, said body portion comprising,
- a foam core having first and second major surfaces, said foam core comprising a multi-layered laminate of open-celled foam material, said foam core having an aperture therethrough between said first and second major surfaces, said aperture situated to lie proximate said selected area of said wearer's body when said protective equipment is upon said wearer's body,
- an enclosure around said foam core, said enclosure formed of a fabric rendered relatively impermeable to air such that a relatively air-tight enclosure is formed around said foam core, said enclosure shaped to follow the contour of said foam core on at least one side of said body portion, and
- means for providing fluid communication between the interior of said enclosure and the exterior of said enclosure;
- a shock absorbing insert adapted to fit within the area defined by said contour of said enclosure around said aperture in said foam core, said insert adapted to withstand an impacting force of a given force magnitude without said insert losing its shock absorbing capability; and
- a shield structure adapted to distribute said impacting force over at least a portion of said body portion.
- 17. The shock absorbing athletic equipment of claim 16, wherein said fabric forming said enclosure is nylon.
- 18. The shock absorbing athletic equipment of claim 17, wherein said nylon fabric is rendered relatively impermeable to air by a polyurethane coating on a surface of said fabric which is to the interior of said enclosure.
- 19. The shock absorbing athletic equipment of claim 16, wherein said means for placing said interior of said enclosure in fluid communication with said exterior of said enclosure comprises at least one aperture through said fabric enclosure.
- 20. The shock absorbing athletic equipment of claim 16, wherein said means for placing said interior of said enclosure in fluid communication with said exterior of said enclosure comprises at least one valve allowing the exit of air from said enclosure and wherein said body portion further comprises at least one valve allowing the passage of air to the interior of said enclosure from exterior of said enclosure.
- 21. The shock absorbing athletic equipment of claim 16, wherein said insert comprises a flexible pad having a given shock absorbing capability.
- 22. The shock absorbing athletic equipment of claim 16, wherein said insert comprises:
- a flexible enclosure defining an internal cavity, said flexible enclosure constructed of a material at least generally impermeable to air; and
- a foam core within said cavity in said enclosure.
- 23. The shock absorbing athletic equipment of claim 22, wherein said insert further comprises means for providing limited air transfer between said cavity in said enclosure and the atmosphere exterior to said enclosure and wherein said foam core constructed at least partially of an open-celled foam material.
- 24. The shock absorbing athletic equipment of claim 16, wherein said insert further comprises a foam core contained within said cavity in said enclosure and wherein said enclosure is inflatable to a pressure greater than one atmosphere.
- 25. The shock absorbing athletic equipment of claim 15, wherein said insert comprises an inflatable/deflatable member.
- 26. The shock absorbing athletic equipment of claim 25, wherein said means for attaching said insert to said body protion comprises a hook and loop fastening mechanism cooperatively arranged between said insert and said body protion.
- 27. The shock absorbing athletic equipment of claim 26, wherein said insert is permanently attached to said body portion.
- 28. The shock absorbing athletic equipment of claim 16, further comprising means for attaching said insert to said body portion.
