<p>This invention concerns a device to protect the cervical vertebrae for use in car and motorcycle racing, the aforementioned device being fitted with means to counteract both the force of inertia, due to strong acceleration, the person may be subjected to, as well as any forces acting on the person as a result of impacts, in the event of an accident, minimising harmful stress to the bone structure. Said protecting device (1) is of the type which includes a support structure (2), substantially fixed the driver torso, a helmet (3), and first means suitable for connecting the said helmet (3) to the said support structure (2), in order to limit the mobility of the said helmet (3) with respect to the said support (2), the said support structure (2) being suitable for transfer on the driver's shoulders the forces coming from the helmet (3), and characterized in that said first means, suitable to connect the said helmet (3) to the said support structure (2), allow the oscillation of said helmet (3) with respect to said support structure (2) in the longitudinal plane of symmetry a, and according to a rotation axis y, perpendicular to said longitudinal plane of symmetry a.</p> |
