Abstract
A sports helmet for protecting a head of a wearer, that comprises: an outer shell comprising an external surface of the sports helmet; inner padding disposed between the outer shell and the wearer's head; an adjustment mechanism operable by the wearer to vary an internal volume of the cavity to adjust a fit of the sports helmet on the wearer's head; and a rotational impact protection device disposed between the external surface of the sports helmet and the wearer's head when the sports helmet is worn, the rotational impact protection device comprising a surface movable relative to the external surface of the sports helmet in response to a rotational impact on the outer shell to absorb rotational energy from the rotational impact, the surface of the rotational impact protection device undergoing displacement when the adjustment mechanism is operated by the wearer to vary the internal volume of the cavity.
