A helmet comprises a protective shell, an energy absorbing layer defining an inner surface of the helmet and a shear component. The shear component extends over one or more areas of the inner surface of the helmet and has an outer surface removably coupled to the inner surface of the helmet. The shear component has a distal inner surface configured to contact a wearer's head, or to support and retain a separate comfort pad configured to contact the wearer's head. In response to an oblique impact to the helmet, the shear component undergoes internal shear to allow displacement between the helmet and the wearer's head.

Helmet

A helmet comprises an outer shell, an outer liner positioned inside of the outer shell, an inner liner positioned inside of the outer liner, at least one displacement device positioned between the inner liner and the outer liner, and at least one helmet coupler that couples at least the outer liner and the inner liner together. The coupler comprises a first head positioned in a first recess in the outer liner, and a second head positioned in a second recess in the inner liner. A coupler post extends through the outer liner and the inner liner to interconnect the first head and the second head. The displacement device produces a damped shear action in response to relative movement of the inner liner and the outer liner. The helmet coupler permits the relative movement and keeps the outer liner and the inner liner coupled together.
