1. A protective helmet including:
- a front shell and a rear shell, wherein in use a wearer'"'"'s head is contained by the front shell and rear shell collectively; and
an emergency release mechanism configured to release the front shell from the rear shell such that the front shell is removable from the rear shell;
wherein the emergency release mechanism comprises;
a tab member located at a dorsal region of the front shell;
a cable system that physically couples;
the tab member to a first movable latch on a first side of the helmet; and
the tab member to a second movable latch on a second side of the helmet, the second side being opposite to the first side;
wherein each movable latch is able to move between;
a first configuration, into which the latch is resiliently biased to lock the front shell to the rear shell at the location of the latch, intoa second configuration, in which the front shell is not locked to the second shell at the location of the latch;
wherein the tab member is configured to be pulled, such that tension in the cable system instantaneously and simultaneously pulls each of the first and second movable latches against their resilient bias from their respective first configurations to their respective second configurations.

12. A protective helmet configured such that:
-
a user'"'"'s head is inserted into the helmet by way of a first operation; and the user'"'"'s head is removable from the helmet by either of; reversing the first operation;
oroperating a safety release mechanism thereby to split the protective helmet into two shells; wherein the emergency release mechanism comprises; a tab member located at a dorsal region of the front shell; a cable system that physically couples; the tab member to a first movable latch on a first side of the helmet; and the tab member to a second movable latch on a second side of the helmet, the second side being opposite to the first side; wherein each movable latch is able to move between; a first configuration, into which the latch is resiliently biased to lock the front shell to the rear shell at the location of the latch, into a second configuration, in which the front shell is not locked to the second shell at the location of the latch; wherein the tab member is configured to be pulled, such that tension in the cable system instantaneously and simultaneously pulls each of the first and second movable latches against their resilient bias from their respective first configurations to their respective second configurations. - View Dependent Claims (13, 14, 15, 16, 17)
