Title
(EN) AIRCREW HELMET OF CAVITY CONSTRUCTION
(FR) CASQUE D'AVIATEUR A CORPS CREUX
Abstract
(EN)
A helmet suitable for use by aircrew constructed in separate, interlocking sections (1, 2) hinged together at the crown and held in place by side latches, characterized in that both sections (1, 2) are of double skin construction with the cavity between the outer and inner skins (5, 4) containing a lightweight foam material (6) that may conveniently be formed so as to define passages (7) as required for cable conduits and air passages. Preferably, the interlocking sections of the helmet comprises a front section on which head-up display optics (3), for example, may be mounted, and a rear section, on which power supply connections and other components may be mounted. To assist the helmet in providing a stable base for instrumentation, an inner liner (9) may be attached to the inner surface of the inner skin of the helmet sections which is moulded or otherwise formed to conform to the head of the particular wearer.
(FR)
L'invention concerne un casque adapté aux besoins des équipages d'aéronefs, constitué de parties distinctes (1, 2), couplées, formant un ensemble articulé au sommet de la tête et assujetties par verrouillage latéral. Il se caractérise par le fait que les parties (1, 2) qui le constituent ont toutes deux une coque double avec une cavité entre les revêtements extérieur et intérieur (5, 4) garni d'un matériau mousse léger (6) pouvant être facilement travaillé pour ménager le passage (7), selon le cas, à des gaines de câbles et des conduits de ventilation. Les parties couplées du casque seront, de préférence, constituées de manière à recevoir, à l'avant, un système de vision tête haute (3), par exemple, et à l'arrière, des raccordements électriques et d'autres composants. Afin de permettre au casque d'offrir un support stable aux instruments, il est possible de placer sur la face intérieure de la coque intérieure un habillage (9) moulé ou mis en forme de quelque autre façon, pour une bonne adaptation à la tête de celui qui le porte.
