BACKGROUND

The present invention relates in general to safety helmets, and more particularly to a triple locking, bi-hemispheric safety helmet which provides a simple method of removal of the safety helmet from the head of a victim after an accident.
Motorcycles are inherently more dangerous than cars. Per km traveled, the number of deaths on motorcycles is about 14 times the number in cars. Motorcycles often have excessive performance capabilities, including rapid acceleration and high top speed. They are less stable than cars in emergency braking and less visible. Motorcyclists are more prone to crash injuries than car drivers because motorcycles are not enclosed, leaving the rider vulnerable to contact with the hard road surface. Therefore, wearing a helmet is important, as helmets are the principal countermeasure for reducing crash-related head injuries, the leading cause of death among unhelmeted riders.
The Michigan State Police claim that “Helmets decrease the severity of injury, the likelihood of death, and the overall cost of medical care. They are designed to cushion and protect riders' heads from the impact of a crash. Just like safety belts in cars, helmets can't provide total protection against head injury or death, but they do reduce the incidence of both.” (Cited from http://wmoon.wordpress.com)
When a victim has endured an accident, there is a high likelihood of sever neck and brain trauma. One primary concern of motorcycle riders is that of the removal of the safety helmet and not knowing if the victim has sustained this injury. The current method of removal the direct pulling-off of the helmet. This extreme measure results in additional disturbance to a potentially already damaged neck/brain, causing paralysis or even death to the victim.
There are several helmets designed to prevent traumatic brain injuries, during a crash. Conventional head gear requires a saw like device to cut the helmet off the head, or the helmet is simply pulled off the head. One such device is described in U.S. Pat. No. 6,138,283 to Kress on Oct. 31, 2000. The device is a multiple-piece removable helmet which can be disassembled on the wearer's head so that, in the event of a medical emergency, the front portion can be removed to afford access to the face of the wearer for administration of first aid and to facilitate the diagnosis of the extent of the injury. A neck brace can also be attached and the injured can be lifted out of the back portion of the helmet. The apparatus for attaching the removable halves includes, in various embodiments, screws, adjustable tension cables, buckles, and spring fingers on one half engaging in indentations in the other with the fingers being secured in place by screws.
A number of other safety helmets are known in the art which can be pulled off the head without using a tool. An example of such devices includes U.S. Pat. No. 7,096,513 issued to Kress which describes a protective helmet with an emergency removal feature. The protective helmet is a multi-piece helmet for protecting the head region of a wearer and providing emergency removal wherein the helmet shell is provided in separate front and rear portions along a seam. A securing mechanism extends between the helmet portions and holds them together in a releaseable manner. The securing mechanism is positioned on the interior surfaces of the helmet shell and finger access ports are provided in the helmet to allow finger access to the securing mechanism from the exterior surfaces of the helmet. This enables the securing mechanism to be finger manipulated to release the securing mechanism and completely separate the front helmet shell portion from the rear helmet shell portion without the requirement of a tool.
Another prior art, U.S. Pat. No. 6,418,564 issued to Sheridan on Jul. 16, 2002, discloses a two piece helmet with optional airbag that is split along a vertical axis between the sides of the helmet to ease removal in the event of an injury. A series of aligned orifices in the helmet portions are joined by a removable cable. The cable ends are attached to each other to secure the helmet portions or to each of the helmet portions. The cable is accessed through removable panels that may also be used to tension the cable. Alternate means for joining the helmet portions include a series of lateral exterior latches opened by the cable. The helmet liner has two overlapping portions to minimize noise and improve weather sealing. An optional inflatable air bag is fitted to a lower perimeter of the helmet. A proximity sensing system inflates the airbag when the vehicle is in motion and the helmet is displaced a certain distance from the vehicle.
Most of the devices have significant disadvantages. One of the above devices requires the use of a tool to gain access to the latching mechanisms. So, the people attending the injured person must always carry the required tool with them. This further complicates and extends the time for effecting helmet separation and removal as the tool must first be retrieved, if available. Moreover, due to the relative complexity of the assembly of some of the above devices, it is time-consuming to dismantle the entire helmet from the head of a victim after an accident. Some other devices require insertion of the finger through the finger access ports provided in the helmet shell to manipulate the securing means positioned on the interior surfaces of the helmet shell. This can perplex would-be rescuers and extend the time for effecting helmet separation and removal.
It is therefore, an object of the present invention to provide a simple, safe apparatus for preventing injury to the head of a motorcycle passenger due to impact/trauma. Another object of the invention is to provide an apparatus that can be dismantled from the head of a victim after an accident thereby providing a simple method of removal and preventing further movement of the head and neck. Yet another object of the invention is to provide a safety helmet having two hemisphere parts fastened at the center with latch-like locks and a removable face shield fastened to the sides of the helmet. Other objects of the present invention will become better understood with reference to the appended Summary, Description and Claims.
