Abstract
An impact attenuating helmet including an outer liner having an inner mating surface, an inner liner positioned under the outer liner and having an outer mating surface configured to be received by the inner mating surface of the outer liner, the inner liner and the outer liner being configured to move relative to each other along a slip plane between outer mating surface of the inner liner and the inner mating surface of the outer liner, and one or more securing attachments, each securing attachment being coupled to the outer liner and being configured to secure the outer liner to the inner liner, each securing attachment comprising a slack element configured to permit a range of movement between the outer liner and the inner liner.

An impact attenuating helmet comprising:
- an outer liner having an inner mating surface;
- an inner liner positioned under the outer liner and having an outer mating surface configured to be received by the inner mating surface of the outer liner;
- and
- one or more securing attachments, each securing attachment being coupled to the outer liner and the inner liner and being configured to secure the outer liner to the inner liner, each securing attachment comprising a slack element comprising an unextended state and a fully extended state and being configured to move between the unextended state and the fully extended state to permit a range of rotational movement between the outer liner and the inner liner,
- wherein one or more of the outer liner or the inner liner comprise a cavity configured to store at least a portion of the length of slack element.
An impact attenuating helmet comprising:
- an outer liner having an inner mating surface;
- an inner liner positioned under the outer liner and having an outer mating surface configured to be received by the inner mating surface of the outer liner;
- and
- one or more securing attachments, each securing attachment being coupled to the outer liner and the inner liner and being configured to secure the outer liner to the inner liner, each securing attachment comprising a slack element comprising a cord having a predetermined length configured to permit a range of rotational movement of the outer liner with respect to the inner liner,
- wherein one or more of the outer liner or the inner liner comprise a cavity configured to store at least a portion of the length of cord.
A method of constructing an impact attenuating helmet, the method comprising:
- securing an outer liner of the impact attenuating helmet to an inner liner of the impact attenuating helmet, the inner liner positioned under the outer liner and configured to move relative to the outer liner;
- coupling a securing attachment to the outer liner and the inner liner to secure the outer liner to the inner liner, the securing attachment comprising a slack element comprising a cord having a predetermined length;
- storing at least a portion of the predetermined length in a cavity of one or more of the outer liner or the inner liner;
- and
- extending the cord to the predetermined length of the cord, the predetermined length of cord corresponding to a range of rotational movement of the outer liner with respect to the inner liner.
