Abstract
A device and method reducing the resistance to emergency safety helmet removal from the head of a crash victim by extracting the shock-absorbing elements from within of the helmet cavity. The removal of he shock-absorbing elements frees the head thereby enabling removable of the helmet with negligible force.
Description
- The present invention relates to safety helmets and, in particular, it concerns removing the helmet from crash victims in a manner that does not exacerbate cervical spine injuries. Safety helmets are typically constructed so that the inner liners secure the helmet snugly on the wearer's head for high-speed travel. In crash situations, the helmet must be removed with the utmost of care to prevent iatrogenically induced neurologic injury. Studies have shown that a force of 16 KG must be applied to the helmet in order to slide it off the head, thereby increasingly the likelihood of exacerbating cervical spine injuries in the process. US patent application 2007/0271688 addresses this need by providing a helmet equipped with removable comfort pads that reduce the pull-off force to a degree. However, these helmets still do not provide the ability to be pulled off the head with the desired, negligible force. The reason stems from the fact that the secure fit afforded by the helmet liner is achieved by a combination of two distinct components, each constructed from a different material. Comfort pads, and shock-absorbing pads, fill a substantial portion of the helmet cavity and secure the helmet on the wearer's head. Since the comfort pads are elastically compressible they are not the primary source of resistance to the helmet sliding off the head. So being, even after removal of the elastic comfort pads, there remains a significant resistance to the removal of the helmet from the head of a crash victim therefore, the danger of exacerbating cervical neck injuries as the helmet is pulled off the crash victim's head remains.
- There is therefore a need for a safety helmet that snugly holds the wearer's head and offers negligible resistance to being pulled off a crash victim's head so as to so as to negate, or to at least minimize to an absolute minimum, the risk of iatrogenically induced neurologic injury.
- The present invention is safety helmet adapted for quick and easy emergency removal.
- According to the teachings of the present invention there is provided, a safety helmet comprising: (a) a rigid, outer shell including a back rim, (b) a slippery assemblage of shock-absorbing bodies, and (c) a flexible pouch connected to the inside of said rigid, outer shell, said slippery assemblage of shock-absorbing bodies being arranged to absorb shock while inside sealed said flexible, pouch and to readily slide out of said flexible pouch when opened so as to enable said flexible pouch to collapse thereby reducing resistance to the safety helmet being pulled off a wearer's head.
- According to a further feature of the present invention there is also provided at least one handle configured to facilitate pulling said slippery assemblage of shock-absorbing bodies out of said flexible pouch.
- According to a further feature of the present invention the shock-absorbent bodies include bodies of extruded polystyrene.
- According to a further feature of the present invention the bodies of extruded polystyrene include blocks.
- According to a further feature of the present invention the bodies of extruded polystyrene include spherical bodies.
- According to a further feature of the present invention the assemblage of shock-absorbing bodies includes a string connecting said shock-absorbing bodies.
- According to a further feature of the present invention the assemblage of shock-absorbing bodies includes a tube containing said shock-absorbing bodies.
- According to a further feature of the present invention the flexible pouch includes a pouch constructed of silicon.
- According to a further feature of the present invention there is also provided a connection arrangement connecting said flexible pouch to said rigid, outer shell.
- According to a further feature of the present invention the connection arrangement includes an arrangement providing multiple connections and disconnections.
- According to a further feature of the present invention the assemblage of shock-absorbing bodies inside flexible pouch extends below the back rim of said rigid shell so as to prevent the back rim from striking the back of the wearer's neck upon backlash.
- According to a further feature of the present invention the flexible pouch includes at least one opening configuration for opening said flexible pouch to enable said slippery arrangement of shock-absorbing bodies to be pulled through said opening.
- According to a further feature of the present invention the opening configuration includes a first of said opening configuration disposed so as to be accessible from either the back or a first side of the wearer and a second of said second opening configurations disposed so as to be accessible from the back or the opposite side of the wearer.
- According to the teachings of the present invention there is provided a method for removing a safety helmet from a crash victim's head comprising: (a) providing a safety helmet with at least one collapsible shock-absorbent-pad having a shock-absorbing material disposed inside a flexible pouch configured to enable said shock-absorbing material to be pulled out of said flexible pouch, (b) opening said flexible pouch, and (c) pulling out at least a portion of said shock-absorbing material from said flexible pouch so as to reduce said collapsible shock-absorbent pad thickness, so as to enable the helmet to easily slide off the head of a crash victim.
