1.Hyperflexion: extreme forward head movement
-
2.Hyperextension: extreme rearward head movement
-
3.Lateral Hyperflexion: extreme sideways head movement
-
4.Axial loading: compression of the spinal column due to the effect of force on the helmet
-
5.Posterior hypertranslation: rearward movement of the head/helmet on the neck.
There is currently no other neck protection system available for karters that can effectively help prevent all of the above potential injuries. The design rationale behind the Leatt-Brace(R) is to bring the head to a controlled stop. This is achieved by providing a padded rigid structure that acts as an alternate load path for neck forces. Helmet impacts otherwise transmitted from the helmet to skull and then to the neck are re-directed from the helmet to the brace to other body structures in a safe way.
The design of the Leatt-Brace(R) prevents the helmet/head from projecting over the brace and therefore prevents a fulcrum action, which has been documented in literature pertaining to the use of collar devices. The Leatt-Brace(R) MOTO KART works with most types of body armor and chest protectors.
The Leatt-Brace(R) MOTO KART is compatible with all motorcycle helmet types and our design allows riders an adequate range of movement. The Leatt-Brace(R) MOTO KART is designed for all levels of competition use, and recreational karting. The Leatt-Brace(R) has been tested by BMW Munich, KTM Works Riders, the SABS (South African Bureau of Standards). It is also endorsed by MSA (Motorsport South Africa).
