Disclosed is an improved protective pad for protecting the human body against impact forces. The pad (10) 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 (16) absorbs and shunts impact forces, while the low density layer (18) acts as a cushion against the human body, and provides for comfort. The pad can be provided with a plurality of holes (12) 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. According to the invention, the holes can be provided with at least one resilient energy absorbing insert.

L'invention concerne un coussinet de protection amélioré, pour protégé le corps humain contre les forces de choc. Ledit coussinet (10) est formé au moyen de couches de mousse polymère à alvéoles fermés haute densité, de mousse polymère à alvéoles fermés faible densité, et d'éléments amortisseurs élastiques et non élastiques. La couche haute densité (16) absorbe et détourne les forces d'impact, alors que la couche à faible densité (18) agit comme un coussin contre le corps humain, et assure le confort de l'utilisateur. Le coussinet peut être doté de plusieurs orifices (12) dans son épaisseur pour assurer la respirabilité et l'évacuation de la chaleur du corps humain, la surface des orifices étant suffisamment importante pour permettre une ventilation adéquate mais pas trop importante de sorte que la protection assurée par le coussinet ne soit pas sensiblement réduite. Le coussinet peut également être doté de plusieurs lignes d'incision sur sa surface et partiellement sur son épaisseur de sorte qu'il soit souple et épouse les contours de la partie du corps humain protégée. Les orifices peuvent être dotés d'au moins un élément rapporté amortisseur élastique.
