Benefits of technology

The present patent relates to a ratchet assembly for a head protection device. The ratchet assembly includes a first cover, a ratchet gear, and a knob. The first cover has an aperture with at least one locking element positioned inside the aperture. The ratchet gear has a plurality of ratchet gear teeth and the knob has a plurality of knob gears. The locking element engages with the ratchet gear teeth and the knob gears. The ratchet gear teeth have ramped surfaces that abut higher portions of the ratchet gear teeth to prevent rotation in one direction. The ratchet assembly can be used in a head protection device to secure the device to a user's head.

Problems solved by technology

In many situations, due to an impact from a falling object, collision with an object, or use of the band over a prolonged period, the buckle or the ratchet mechanism becomes inefficient and tends to loosen unwantedly.
The Applicant has identified several technical challenges associated with ratcheting systems used for hard hats.
