Abstract (en)
[origin: CA3188111A1] The structure for absorbing impact energy comprises a core (15) having a first surface (10) exposed to impacts, and reinforcements which are distributed inside the core (15) and have frictional interfaces with the core material. The reinforcements comprise first reinforcements (16) that are positioned in a first reinforced region (12) adjacent to the first surface (10) and have main directions of resistance forming an angle of less than 45° with the first surface.
