A safety helmet includes an outer shell having a front receptacle disposed on a front side of the outer shell and a rear receptacle disposed on a rear side of the outer shell. A first accessory device having a first mating receptacle formed thereon is releasably mountable onto each of the front receptacle or the rear receptacle of the outer shell, and a second accessory device having a second mating receptacle formed thereon is releasably mountable onto each of the front receptacle or the rear receptacle of the outer shell.

A smart helmet system includes a helmet and a mobile communication device. The smart helmet includes a helmet body, a detection module and a wireless transmission module. The detection module is applied to detect at least one motion parameter of the helmet. The wireless transmission module is to transmit the motion parameter. The mobile communication device stores an operation regulation to define at least one predetermined operation function of the mobile communication device corresponding to at least one set motion track. The mobile communication device is to receive the motion parameter to accordingly determine a detected motion track and further to activate the predetermined operation function when the detected motion track is complied with the set motion track, so as to operate the mobile communication device according to the predetermined operation function.

A hinge mechanism for attaching ear accessories to a helmet allows an accessory to be attached at a point outside the helmet shell utilizing, for example, a slidable mounting rail, and to reach under the edge of the helmet shell so that the accessory is supported in contact with the wearer's head. The hinge mechanism is well suited for use in connection with military helmets that have a “bulge” or protrusion over the ear.

A lighted visor and method of retrofitting a protective suit with a lighted visor are disclosed. The lighted visor includes a shield and at least one light source that is conformable to the shape of the shield or visor on which is it disposed.

Aspects of the present invention are directed to helmet padding systems. One helmet padding system includes a rigid shell and a spacing pad. The rigid shell is configured to cover a top of a user's head and be worn under a baseball cap. The rigid shell includes an opening formed in an area of the rigid shell opposite the front of the user's head when the rigid shell is worn on the user's head. The spacing pad is positioned within the rigid shell. The spacing pad includes a layer of elastomeric material. The helmet padding system may further include the baseball cap positioned overtop the rigid shell. The baseball cap has a cut-out in a rear portion thereof.
