Patent

CA 2568989

The invention relates to a protective helmet comprising an inner hood (1) consisting of a spacer knitted fabric consisting of a monofilament yarn. Said hood is covered by a pneumatic central layer (4) which can be pressurised by means of compressed air and can be inflated by means of an air pump (5) which can be, for example, removed and provided with valves (6). An outer layer (10) consists of an inner textile layer (11) which lies over the pneumatic central layer (4), and plates (12) which are fixed to the textile layer (11), for example by adhesion. Said plates (12) consist, for example, of plastic, composite materials, or natural materials. The plates (12) can be arranged in such a way that joints (13) are created thereinbetween, the outer layer (10) thus being provided with a certain elasticity in order to cater for different head shapes and sizes.

L'invention concerne un casque de protection qui est composé d'une coiffe intérieure (1) constituée d'un tissu à maille à écartement en fil monofilament. Cette coiffe est recouverte d'une couche centrale pneumatique (4) qui peut être mise sous pression au moyen d'air comprimé et qui peut être gonflée à l'aide d'une pompe à air (5), par exemple amovible et équipée de soupapes (6). Une couche extérieure (10) est constituée d'une couche textile intérieure (11) posée sur la couche centrale pneumatique (4), ainsi que de plaques (12) qui sont fixées sur la couche textile (11), par exemple, par collage. Ces plaques (12) peuvent être en plastique, en matériaux composites ou en matériaux d'origine naturelle. Les plaques (12) peuvent être disposées de manière à ce que des fentes (13) soient ménagées entre elles, ce qui donne à la couche extérieure (10) une certaine élasticité permettant de prendre en compte différentes tailles et formes de tête.
