Disclosed is an improved protective pad for protecting the human body against impact forces. The pad is formed using layers of high density closed-cell polymer foam low density closed-cell polymer foam, and resilient or non-resilient energy absorbing inserts. The high density layer absorbs and shunts impact forces, while the low density layer acts as a cushion against the human body, and provides for comfort. The pad can be provided with a plurality of holes through its thickness to provide for breathability and release of heat from the human body, the surface area of the holes being great enough to allow for adequate ventilation but not so great as to significantly decrease the protection offered by the pad. The pad can also be provided with a plurality of score lines across its surface and partially through its thickness to provide for flexibility and conformability to the part of the human body being protected.
A protective pad for protecting an area of the human body against impact forces, the pad having an inner surface, an outer surface, and a thickness, the pad comprising a first layer of high density closed-cell polymer foam, a second layer of low density closed-cell polymer foam, and at least one resilient energy absorbing insert, the layers and insert being fixed together to provide a lightweight pad, high resistance to impact forces, and comfort when applied to the area of the human body.
A protective pad, having at least one resilient energy absorbing insert, a thickness and a weight, for protecting a predefined area of the human body against impact forces and providing a force reduction of at least 40 percent, the pad being less than about 20 millimeters in thickness and less than about 100 grams in weight, the pad having a ratio of percentage force reduction per gram weight of the pad, as measured in a surrogate hip drop impact test, of from about 0.25 percent per gram to about 8.00 percent per gram.
A protective pad for protecting an area of the human body against impact forces, the pad having an inner surface, an outer surface, and a thickness, the pad comprising a first layer of relatively high density closed-cell polymer foam, a second layer of low density closed-cell polymer foam, and at least one resilient energy absorbing insert, the insert having a lower hardness than the first layer, the layers and insert being attached together to provide a lightweight pad, high resistance to impact forces, and comfort when applied to the area of the human body.
A protective pad for protecting an area of the human body against impact forces, the pad having an inner surface, an outer surface, and a thickness profile, the pad comprising a first layer of high density closed-cell polymer foam, a second layer of low density closed-cell polymer foam, and at least one resilient energy absorbing insert, the layers and insert being attached together to provide a lightweight pad, high resistance to impact forces, the thickness profile having smoothly tapering sides in all directions to define a domed cross section with the first layer residing on the convex side defined by the cross section to provide comfort when applied to the area of the human body.
