Abstract
Helmet (1) comprising: a shell (2); a head receiving system (3); at least one cellular energy-absorbing structure (4) comprising a plurality of interconnected open-cells (9) configured to absorb energy by deforming during an impact on the shell (2); at least one clamping device (5) comprising a base (6) and a counter-base (7) connected to each other via a collapsible body (8) sized so as to enter one or more open-cells (9) of the cellular energy-absorbing structure (4); wherein the base (6) or the counter-base (7) of the clamping device (5) comprises a low friction part (26) configured to enable a relative movement of the cellular energy-absorbing structure (4) and the clamping device (5) with respect to the shell (2).
Claims21
A helmet comprising:
- a shell;
- a head receiving system;
- at least one cellular energy-absorbing structure comprising a plurality of interconnected open-cells configured to absorb energy by deforming during an impact on the shell;
- at least one clamping device comprising a base and a counter-base connected to each other via a collapsible body, the collapsible body passes through one or more open-cells of the cellular energy-absorbing structure, and the base and the counter-base are opposite to each other with respect to the cellular energy-absorbing structure to connect the clamping device to the cellular energy-absorbing structure;
- wherein the base or the counter-base of the clamping device comprises a low friction part, the low friction part is arranged over an outer surface of the base or counter-base facing the shell to enable the base or counter-base to slide over the shell, allowing a relative movement of the cellular energy-absorbing structure, together with the clamping device with respect to the shell.
