A protective headgear compression member (10) includes a hollow compression cell (12) having a top wall (22), a bowed side wall (24) and a bottom wall (26,28) and a liner element (14) secured to that bottom wall coaxially to said cell. The lin-er element is composed of a flexible envelope (32) substantially-filled with resilient material (34,36) and the envelope is secured to the bottom wall via an axially flexible connection to prevent the bottoming out of the liner element against the bottom wall of the cell.

L'invention porte sur un élément de compression de casque de protection (10), lequel élément comprend une cellule de compression creuse (12) comprenant une paroi supérieure (22), une paroi latérale arquée (24) et une paroi inférieure (26, 28) et un élément de revêtement (14) fixé à cette paroi inférieure, coaxialement à ladite cellule. L'élément de revêtement est constitué par une enveloppe souple (32) sensiblement remplie par un matériau élastique (34, 36), et l'enveloppe est fixée à la paroi inférieure par l'intermédiaire d'une liaison axialement souple afin d'empêcher l'élément de revêtement de venir en contact avec la paroi inférieure de la cellule.
