Abstract

Disclosed is a unique spine protector for use with or without protective clothing and in particular, in bomb disposal suits or in sports related activities. The protector is made up of a plurality of overlapping elongate support members having a central recess in the mid-portion thereof such that when an external force is applied to the spine protector, the force exerted is transmitted to the spinal muscles and/or thoracic support structures on either side of the vertebrae while the vertebrae remain minimally loaded. The spine protector is made up of two sizes of support members which overlap each other in mating relationship and are loosely joined so that the spine protector can flex in three dimensions.

Claims

1. A flexible spine protector for use with protective clothing, sports related activity or any other activity benefiting from spinal protection comprising:

a plurality of elongate substantially rectangular rigid support members and a plurality of resilient elongate substantially rectangular underpads;

said support members being comprised of a plurality of upper support members and lower support members;

each of said upper members being adapted to fit over two adjacent lower support members in mating relationship;

said lower support members being mounted on said underpads;

said underpads and support members being adapted in operation to lie perpendicular to the longitudinal axis of the spine;

said upper support members being spaced apart from adjacent upper support members;

said lower support members mounted on said underpads being space apart from adjacent lower support members mounted on said pads;

said support members being connected to one another in matingly overlapping relationship by a fastening means;

said support members further including a concave central recess on the underside thereof; and

said recess being adapted to lie directly over the vertebrae of the wearer, when in use.

2. A spine protector as claimed in claim 1, wherein said support members comprise:

an upper surface which includes at least two curvilinear upwardly projecting ribs which extend along the length of said support members and terminate adjacent the ends thereof;

each of said ribs having its maximum height at the mid-point of said support members.

3. A spine protector as claimed in claim 2, wherein said lower support members include ribs which are shorter in length and narrower in width than said upper support members, such that said ribs of said upper support members overlap said ribs of said lower support members in mating relationship.

4. A spine protector as claimed in claim 3, wherein said fastening means comprises:

a plurality of fasteners;

each of said fasteners passing through at least one rib of said upper support member and one rib of said lower support member in a direction transverse to the longitudinal axis of said ribs.

5. A spine protector as claimed in claim 4, wherein two of said fasteners connect each pair of overlapping ribs of said upper and lower support members.

6. A spine protector as claimed in claim 4, wherein said ribs are loosely connected by said fasteners such that said spine protector is adapted to flex in three dimensions.

7. A spine protector as claimed in claim 1, wherein said upper support members are longer than said lower support members and include on each end thereof, a downwardly projecting lip.

8. A spine protector as claimed in claim 1, wherein a top end and a bottom end lower support member may include fastener apertures by which supporting attachment to a pouch or sleeve can be established.

9. A spine protector as claimed in claim 8, wherein said concave central recess of said top end lower support member is cut-away at its top side to facilitate rearward movement of an occupant'"'"'s head.

10. A spine protector as claimed in claim 8, wherein said bottom end lower support member is tapered toward the lowermost portion of said spine protector.

11. A spine protector as claimed in claim 1, wherein at least one of said underpads and one of said support members is substantially greater in width than the remainder of said underpads and said support members.
