Abstract

L'invention concerne un dispositif portatif pour déployer un filet de retenue, qui peut être utilisé par le public de manière simple, fiable et sûre et dans lequel une section d'éjection de filet peut être remise en place par le public de manière simple, fiable et sûre. Le dispositif portatif pour déployer un filet de retenue présente une section d'éjection de filet de retenue permettant d'éjecter le filet de retenue par pression de gaz ; une section d'activation pour activer la section d'éjection de filet de retenue ; et un adaptateur pour connecter de manière amovible la section d'éjection de filet de retenue et la section d'activation. La section d'éjection de filet de retenue inclut le filet de retenue ; des poids disposés à intervalles prédéterminés sur le bord périphérique du filet de retenue ; une section de réception des poids pour former des ouvertures d'éjection qui éjectent les poids suivant un angle prédéterminé et recevant les poids ; une section de réception de filet de retenue pour recevoir le filet de retenue ; un allumeur pyrotechnique pour produire une pression de gaz par la combustion d'une substance combustible ; et un moyen d'éjection pour éjecter les poids et le filet de retenue par pression de gaz produite par l'allumeur pyrotechnique.
