Abstract
Technology for protective helmets is provided, with a particular focus on rear opening full-face helmets. Embodiments are primarily focussed on an emergency release mechanism for such helmets, which allows the helmet to be separated into a front and rear shell thereby to facilitate removal from a wearer's head with minimal stress to the neck.
Claims21
A protective helmet including:
- a front shell;
- and
- a rear shell hingedly movable with respect to the front shell to provide:
- an open configuration in which the helmet is able to be placed on a user's head or removed from the user's head;
- and
- a closed configuration wherein the rear shell is releasably lockingly engaged to the front shell for securely containing the head within the helmet;
- a multiple point locking system including:
- an upper dorsal connection for hingedly connecting the rear shell to front shell, thereby to enable movement between the closed configuration and the open configuration;
- one or more lower side connections for releasably locking the front shell to the rear shell thereby to selectively lock the helmet in the closed configuration;
- and
- an emergency release mechanism configured to simultaneously release the hinge and unlock the lower side connections such that the rear shell is removable from the front shell.
