Abstract
The invention concerns a cranio-cerebral protective helmet adapted to the anatomy of the head and to the neurosurgical knowledge. The helmet is adapted to the resistance of different regions of the skull vault thereby reducing cranio-cerebral lesions and post traumatic neurological disorders.
Claims18
A cranio-cerebral protective helmet, comprising:
- (a) a cap comprising:
- first zones of low compressive crushing resistance adapted to be located in front of the fragile zones of the cranium of the wearer, the first zones being formed by at least one of:
- furrows on at least one surface of the cap, cavities in a thickness of the cap, and soft zones;
- and
- second zones of high compressive crushing resistance adapted to be located in front of the zones of maximum resistance of the cranium of the wearer, the second zones being formed by at least one of:
- smaller furrows, smaller cavities, and harder zones;
- and
- (b) a shell comprising at least one of:
- low resistance zones adapted to be located in front of at least two of the maximum resistant zones of the cranium of the wearer, the low resistance zones being situated in a thickness of the shell and being formed by at least one of:
- (i) a reduction of the shell thickness and construction of depressions and furrows;
- (ii) orifices;
- (iii) junctions between sectors of the shell;
- and
- (iv) a modification of at least one of:
- a fiber density and an orientation in a case of a shell constructed of composite materials;
- low resistance layers adapted to be located in front of at least two of the maximum resistant zones of the cranium of the wearer, the low resistance layers being situated on at least one of an internal shell surface and an external shell surface, and being formed by at least one of compact structures and alveolar structures;
- and
- reinforced zones adapted to be located in front of the fragile zones of the cranium of the wearer, the reinforced zones being formed by at least one of:
- rigid and resistant structures, and a reduction of a curvature radius of the shell towards the periphery of the reinforced zones.
