Abstract
Helmets and methods for manufacturing a helmet are described. An example helmet includes a shell and a shock absorbing liner attached to the shell. The shock absorbing liner includes a cavity. The helmet a shock absorbing insert formed of a material different than the material of the shock absorbing liner. The cavity is configured to retain the shock absorbing insert.
Claims21
A helmet, comprising:
- a shell;
- a shock absorbing liner attached to the shell having a liner bottom surface;
- a cavity formed in the shock absorbing liner;
- and
- a shock absorbing insert provided in the cavity having an insert bottom surface, wherein the liner bottom surface and the insert bottom surface are adjacently arranged, the shock absorbing insert having a thickness equal to or less than a depth of the cavity of the shock absorbing liner, and the shock absorbing insert is porous and formed of a material different than a material of the shock absorbing liner, wherein the cavity is configured to retain the shock absorbing insert, and wherein the shock absorbing insert comprises a honeycomb structure configured to provide an improved shock absorbing protection as compared with the material of the shock absorbing liner.

A helmet comprising:
- a shell;
- a shock absorbing liner attached to the shell;
- a cavity formed in the shock absorbing liner;
- and
- a shock absorbing insert provided in the cavity, wherein the shock absorbing insert is porous and formed of a material different than a material of the shock absorbing liner, wherein the cavity is configured to retain the shock absorbing insert, wherein the shock absorbing insert comprises a honeycomb structure configured to provide an improved shock absorbing protection as compared with the material of the shock absorbing liner, and wherein the cavity is configured such that a distance along a first side of the shock absorbing insert near the shell is greater than a distance along a second side of the shock absorbing insert opposite the first side.
2 more elements
A helmet, comprising:
- a shell comprising a vent;
- a shock absorbing liner attached to the shell, the shock absorbing liner comprising a cavity;
- and
- a shock absorbing insert positioned in the cavity, wherein the cavity is configured to retain the shock absorbing insert, wherein the shock absorbing liner is made from a different material than the shock absorbing insert, the shock absorbing insert comprising a honeycomb structure comprising a packed array of tubes configured to allow air to flow through the tubes, and wherein the cavity and the shock absorbing insert in the cavity are at least partially aligned with the vent to enable air to flow through the vent and the tubes of the honeycomb structure in the cavity between an exterior and an interior of the helmet.
1 more element
A helmet, comprising:
- a shell;
- a shock absorbing liner adjacent to and attached to the shell;
- a cavity formed in the shock absorbing liner;
- and
- a shock absorbing insert formed of a porous material different than a material of the shock absorbing liner, wherein the cavity is configured to retain the shock absorbing insert, and wherein the porous material of the shock absorbing insert is a porous honeycomb structure including an array of open-ended tubes configured to allow air to flow into the open-ended tubes in a direction normal to an inner surface of the shell and through from one side of the porous honeycomb structure to an opposite side of the porous honeycomb structure.
2 more elements
A helmet comprising:
- a shell having an inner surface;
- a shock absorbing liner adjacent to and attached to the shell;
- a cavity formed in the shock absorbing liner;
- and a shock absorbing insert formed of a porous material different than a material of the shock absorbing liner, wherein the cavity is configured to retain the shock absorbing insert, and wherein the porous material of the shock absorbing insert is a porous honeycomb structure having a plurality of tubes that allow air to flow through from one side of the porous honeycomb structure to an opposite side of the porous honeycomb structure, wherein the plurality of tubes include a longitudinal axis arranged at an angle between 0° and 45° to a line normal to a point adjacent to the respective tube on the inner surface of the shell.
