Abstract
Abstract A protective body support for use to protect a wearer's knee, or other such body part, re-directs and dissipates the forces associated with an impact delivered to the body support in such a manner as to prevent the application of a force to the body that is sufficient to harm that body. The body support includes plurality of triangular compartments that are attached at the apex of the triangles to an adjacent element of the support. Energy-absorbing beads are contained in the compartments, and the triangular shapes are oriented so that forces applied to the support are re-directed against the apexes so as to apply shear forces thereto. The apexes are attached so that at a predetermined level of impact force applied to the support, the resultant component applied against the apexes will rupture at least one of the apex connections thereby allowing the beads to spill out of the support compartment located adjacent to the ruptured apex. The rupturing of the apex connection dissipates some of the impact force, and the connection is formed so that it will rupture before the components of the impact force other than the shear force will be low enough so as not to harm the body being protected by the support. The support is adapted to rupture in a manner so as to permit the beads to flow out of the support to further dissipate the impact force and prevent harm to the wearer's body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
249 words
A new and improved protective body support for use on a user's body comprising: a flexible casing means positionable against a user's body; energy absorbing bead means contained in said flexible casing means; baffle means positioned within said flexible casing means, said energy absorbing bead means being retained within said baffle means, said baffle means including two sheets of flexible material, with a first sheet of said two sheets defining a plurality of triangle-shaped compartments each having a first sheet apex that is adapted to be attached to the second sheet of said two sheets, and said second sheet defining a plurality of triangle-shaped compartments each having a second sheet apex that is adapted to be attached to the first sheet; a break-away joint attaching each of said first sheet baffle means apexes to said second sheet, and each of said second sheet baffle means apexes to said first sheet; said triangle-shaped compartments having walls that are positioned and oriented to position and orient the bead means within said compartments with respect to said break-away joints so that impact energy associated with an impact to the casing means is re-directed through said bead means to apply shear forces to said break-away joints, said break-away joints being adapted to rupture under the influence of a predetermined amount of shear force, with said predetermined amount of shear force being associated with an impact force on said casing means that is less than that impact force which would damage the user's body.
Claim 2
Dependent Claim
249 words
A new and improved protective body support for use on a user's body comprising: a flexible casing means positionable against a user's body; energy absorbing bead means contained in said flexible casing means; baffle means positioned within said flexible casing means, said energy absorbing bead means being retained within said baffle means, said baffle means including two sheets of flexible material, with a first sheet of said two sheets defining a plurality of triangle-shaped compartments each having a first sheet apex that is adapted to be attached to the second sheet of said two sheets, and said second sheet defining a plurality of triangle-shaped compartments each having a second sheet apex that is adapted to be attached to the first sheet; a break-away joint attaching each of said first sheet baffle means apexes to said second sheet, and each of said second sheet baffle means apexes to said first sheet; said triangle-shaped compartments having walls that are positioned and oriented to position and orient the bead means within said compartments with respect to said break-away joints so that impact energy associated with an impact to the casing means is re-directed through said bead means to apply shear forces to said break-away joints, said break-away joints being adapted to rupture under the influence of a predetermined amount of shear force, with said predetermined amount of shear force being associated with an impact force on said casing means that is less than that impact force which would damage the user's body.
Claim 3
Dependent Claim
19 words
The protective body cover defined in claim 1 wherein said casing means comprises two outer sheets of neoprene rubber.
Claim 4
Dependent Claim
46 words
The protective body cover defined in claim 2 wherein said casing means includes a rupture location that ruptures to permit said bead means to flow out of said casing means when the force applied to said casing means exceeds said predetermined force by a pre-selected amount.
Claim 5
Dependent Claim
22 words
The protective body cover defined in claim 3 wherein said rupture location is adjacent to an end edge of said casing means.
Claim 6
Dependent Claim
12 words
The protective body cover defined in claim 4 further including air pockets.
Claim 7
Dependent Claim
18 words
The protective body cover defined in claim 5 wherein said triangle shaped compartments are isosceles triangles in shape.
Claim 8
Dependent Claim
33 words
The protective body cover defined in claim 6 further including additional sheets each fixedly secured between one of said baffle means first and second sheets and one of said casing means outer sheets.
Claim 9
Dependent Claim
43 words
The protective body cover defined in claim 7 further wherein said additional sheets form trapezoidally shaped pockets having energy absorbing bead means contained therein, said trapezoidally shaped pockets having walls that contact the walls of said triangle shaped compartments to support such walls.
