Abstract:
An adjustable protective helmet for sporting activities comprising a first shell and second shell, one of said shells covering the forehead and a portion of the sides of a wearer's head, and the other one of said shells covering the top, back and a portion of the sides of a wearer's head; said first and second shells having respective cooperating inner and outer overlapping portions extending transversely across the top portion of the wearer's head for connecting together said shells to form a bowl shaped shell assembly circumscribing the wearer's head: said inner overlapping portion lying inwardly of said outer overlapping portion and its associated shell; said shells movable relative to one another in said overlapping portions to provide size adjustability of said helmet; said helmet including a shock absorbing liner inside said shell assembly; said shell assembly comprising a ramp defined by a plurality of raised formations on the inside surface of said shell assembly, said ramp adjacent and facing a free edge of said inner overlapping portion thereby increasing the contact surface area between said liner and said shell assembly around said overlapping portions in order to reduce the concentration of force of an impact in the vicinity of said overlapping portions.
