Abstract
A helmet having an outer liner with an inward-facing surface, an inner liner with an outward-facing surface that interfaces with the inward-facing surface of the outer liner, and a flexible tether coupling the outer liner to the inner. The inner liner is slidably coupled to the outer liner via a plurality of return springs, the plurality of return springs biasing the inner liner to a first position with respect to the outer liner.
Claims20
A helmet, comprising:
- an outer liner comprising an inward-facing surface;
- an inner liner comprising an outward-facing surface configured to interface with the inward-facing surface of the outer liner;
- a plurality of return springs configured to bias the inner liner to a first position with respect to the outer liner, the outer liner configured to rotate with respect to the inner liner to a second position different from the first position upon an impact to the helmet, the plurality of return springs configured to attenuate a portion of energy imparted by the impact to move the inner liner toward the first position with respect to the outer liner;
- and
- a plurality of recesses in which the plurality of return springs is seated, the plurality of recesses being formed in either the outer liner or the inner liner.
