A body limb protection system includes an outer layer, an inner layer, and a force dampening and defusing structure. The outer layer includes a first material composition and has an exterior surface that includes a substantially planer area. The inner layer includes a second material composition and has a shape corresponding to a body limb portion. The force dampening and defusing structure is positioned between the inner layer and the outer layer. The force dampening and defusing structure has a shape corresponding to a difference between the shapes of the inner and outer layers. The force dampening and defusing structure includes a plurality of components arranged to reduce pressure on the body limb portion when a force is applied to the substantially planer area.

An impact plate system is provided herein comprising a moldable plate having center, a first surface, and a second surface opposite the first surface. The first surface and the second surface define a thickness therebetween. The thickness is between 4 mm and 7 mm. The moldable plate is defined by a perimeter edge, which comprises one or more curved corners having a predetermined radius of curvature between 18 mm to 28 mm.

Generally described, aspects of the disclosed subject matter are directed to impact mitigating membranes. In accordance with aspects of the present disclosure, the impact mitigating membranes generally include a laminar core having a first lamina and a second lamina coupled to the first lamina and configured to shift relative to the first lamina to dissipate kinetic energy resulting from an oblique impact force. The laminar core may include a lubricating layer or self-lubrication between the lamina to reduce friction. In general, the laminar core is surrounded by first and second encapsulating layers positioned adjacent each lamina. An anchoring attachment coupled to one or more of the first and second encapsulating layer and associating with the laminar core constrains relative lateral motion between the laminar core and the first and second encapsulating layers.

Provided with a sleeve supporter which can cover a surface of an region including an instep, a sole, a heel and an ankle of a foot and a belt-type supporter which is attached to the sleeve supporter and attachable to the foot on the sleeve supporter: the belt-type supporter is provided with an ankle belt, a plantar heel hold belt, an affected-part pressing belt and a posterior heel hold belt: the sleeve supporter is made of cloth having an extension larger than that of the belt-type supporter, yarns used therefor have a thickness 30 denier to 70 denier (both inclusive) and a clothing pressure thereof is 10 mmHg to 20 mmHg (both inclusive).

Sport boots have an outer shell and an ankle compression system attached to and positioned within the outer shell to apply selective compressive force against an anterior ankle portion of a person's foot when wearing the boot. The ankle compression system includes an ankle compression member positioned forwardly adjacent to the anterior ankle portion and at least one medial positioning band having a lower terminal end immovably fixed to a medial edge portion of the strobel and having an opposite end operatively associated with the ankle compression member. An adjustment lace is connected to the ankle compression member and is operatively connected to a tightening member positioned on a lateral side of the outer shell so that operation of the tightening causes the adjustment lace to forcibly draw the ankle compression member toward and exert a selective compressive force against the anterior ankle portion of the person's foot.

A modular protective system for protecting a joint of a human or an animal is provided. The modular protective system can include modular pads for attachment to a garment fitted to surround the joint. The modular pads can include an elongated upper pad for positioning above the joint, an elongated lower pad for positioning below the joint, separated from the elongated upper pad, and a flexible and stretchable intermediate pad. The elongated upper pad and the elongated lower pad each include an undersurface for attachment to the garment. The flexible and stretchable intermediate pad can include a top cap portion, for positioning on top of the joint, and two side portions.

Provided is a joint protection device, including a joint protection body whose longitudinal and horizontal shapes match a shape of a joint, joint protection body being an integrally formed rigid hollow housing with an opened bottom and including a front supporting portion and side supporting portions respectively wrapping a front surface and side surfaces of joint to provide front and side support for joint; at least one notch being provided in a portion, close to a joint movement area, of joint protection body, and dividing joint protection body into a plurality of joint pieces; adjacent joint pieces being connected by two local junctions respectively provided at appropriate positions on two sides of joint protection body, and capable of rotating with local junctions as rotation fulcrums; and when joint pieces rotate around rotation fulcrums to a limiting position, adjacent joint pieces coming into contact with each other and stopping rotating.

An impact force dampening and defusing structure includes a plurality of components arranged in a grid array. A component has a three-dimensional geometric shape that includes an impact receiving surface area and an impact defusing surface area. The impact defusing surface area is larger than, and a distance d from, the impact receiving surface area. The component includes a material composition and, when an impact force strikes the impact receiving surface area of the component and the impact force dampening and defusing structure is in position to protect a body part, the component contributes to reducing pressure on the body part based on the material composition, the distance d, the impact receiving surface area, and the impact defusing surface area.

The invention relates to a leg pad for a hockey player. The leg pad extends along a longitudinal axis and comprises an upper portion, a bottom portion and a band. The upper portion has a knee cap for covering a knee joint of the player. The bottom portion has an upper shell for covering a substantial part of a shin of the hockey player and a lower shell for at least partially covering the shin and ankle of the hockey player. The band extends along part of a periphery of the upper shell and part of a periphery of the lower shell. The band interconnects the upper shell and the lower shell to one another wherein the lower shell is movable relative to the upper shell between a first position and a second position in response to flexion of the ankle.
