The present disclosure relates to an impact absorbing helmet design that uses springs oriented in the opposite direction of relative movement between the head and the helmet to absorb linear and rotational impacts. These springs will increase the total amount of work being done by the helmet and increase the time of impact, reducing the acceleration experienced by the brain when compared to current helmets on the market. The helmet is constructed and arranged to effectively absorb rotational forces on the head because of a rotationally independent inner lining and outer shell attached by springs.

The invention relates to a multi-step method with a number of processes and sub-processes that interact to allow for the selection, design and/or manufacture of a protective sports helmet for a specific player, or a recreational sports helmet for a specific person wearing the helmet. Once the desired protective sports helmet or recreational sports helmet is selected, information is collected from the individual player or wearer regarding the shape of his/her head and information about the impacts he/she has received while participating in the sport or activity. The collected information is processed to develop a bespoke energy attenuation assembly for use in the protective helmet. The energy attenuation assembly includes at least one energy attenuation member with a unique structural makeup and/or chemical composition. The energy attenuation assembly is purposely engineered to improve comfort and fit, as well as how the helmet responds when an impact or series of impacts are received by the helmet.

A smart helmet system, a helmet, and a transportation vehicle are provided. The smart helmet system includes a helmet body, a first detection module, a second detection module, and a third detection module. The helmet body includes a first lock part of a helmet lock and retention straps; a second lock part of the helmet lock is mounted on the transportation vehicle. The first detection module is configured to detect a connection state between the first lock part and the second lock part and send information of the connection state to a control module. The second detection module is configured to detect a wearing state of the helmet and send information of the wearing state to the control module. The third detection module is configured to detect an engagement state of the helmet buckle and send information of the engagement state to the control module.

An impact reducing headgear is disclosed which utilizes dynamically responsive materials which undergo physical changes during exposure to impact forces, such that physical changes or phase changes absorb energy. The helmet may be constructed with a dual shell structure and a bladder, where the dynamically responsive materials may be contained.
