Description

DISPOSITIF DE GONFLAGE DE MULTIPLES ENVELOPPES  DEVICE FOR INFLATING MULTIPLE ENVELOPES
La présente invention concerne un dispositif portable de sécurité apte au gonflage de multiples enveloppes lors d'un déclenchement d'une avalanche. Un dispositif de sécurité est basé sur le gonflage d'une enveloppe de type airbag, permettant de réduire ou d'empêcher l'ensevelissement d'un usager lorsqu'il est emporté par une avalanche. The present invention relates to a portable security device capable of inflating multiple envelopes during an avalanche trigger. A safety device is based on the inflation of an airbag-type envelope, making it possible to reduce or prevent the burial of a user when he is carried away by an avalanche.
Des dispositifs conventionnels permettent le gonflage d'une enveloppe par l'aspiration d'air environnant, provoquée par une alimentation en gaz comprimé, accélérée par effet venturi, tels que décrits par les documents US 6,220,909, US 2013/0283510 et EP 2 548 619. Conventional devices allow the inflation of an envelope by the surrounding air suction, caused by a compressed gas supply, accelerated by venturi effect, as described by the documents US 6,220,909, US 2013/0283510 and EP 2 548 619 .
De nouveaux dispositifs ont été développés ces dernières années, permettant un gonflage d'une enveloppe uniquement par de l'air environnant, insufflé par une turbine alimentée électriquement, tels que divulgués par les documents US 2012/ 0060267 et US 8,777,684. New devices have been developed in recent years, allowing inflation of an envelope only by surrounding air, blown by an electrically powered turbine, as disclosed by US 2012/0060267 and US 8,777,684.
L'inconvénient majeur d'un dispositif à une enveloppe indépendante est qu'il est inutilisable lors d'un dysfonctionnement du déploiement de l'enveloppe, d'un éclatement, d'une déchirure ou d'un perçage de cette dernière. Le document US 6,220,909 divulgue un système de sécurité à deux enveloppes indépendantes, gonflées par une bouteille de gaz comprimé. Chacune des enveloppes est associée à une chambre d'admission, un système venturi et un cône d'accélération. The major disadvantage of a device to an independent envelope is that it is unusable during a malfunction deployment of the envelope, bursting, tearing or drilling of the latter. US 6,220,909 discloses a security system with two independent envelopes inflated by a cylinder of compressed gas. Each of the envelopes is associated with an intake chamber, a venturi system and an acceleration cone.
Ce dispositif à plusieurs enveloppes a l'avantage d'avoir des systèmes de gonflage indépendants, mais est par conséquent volumineux, lourd et encombrant à transporter. This multi-envelope device has the advantage of having independent inflation systems, but is therefore bulky, heavy and bulky to carry.
Le document US 2012/0060267 décrit un système de gonflage par une turbine, alimentée par une double entrée, débouchant dans deux enveloppes gonflables. Ces deux enveloppes gonflables ne sont pas indépendantes et ne permettent pas de fonctionner lors d'une éventuelle dégradation. US 2012/0060267 discloses a turbine inflating system, fed by a double inlet, opening into two inflatable envelopes. These two inflatable envelopes are not independent and do not allow to operate during a possible degradation.
La présente invention propose ainsi un dispositif portable de sécurité apte au gonflage de multiples enveloppes permettant de pallier aux inconvénients précités. The present invention thus provides a portable safety device capable of inflating multiple envelopes to overcome the aforementioned drawbacks.
Ainsi, le dispositif portable de sécurité apte au gonflage de multiples enveloppes, selon l'invention comprend au moins une entrée d'air environnant, au moins un moyen de gonflage, au moins une zone d'air ou de gaz enrichi, au moins un clapet anti-retour, au moins un cône d'accélération connecté à au moins une enveloppe gonflable, tandis qu'il comprend au moins une paroi séparatrice, qui compartimente au moins l'extrémité d'au moins un cône d'accélération débouchant dans au moins deux enveloppes gonflables sensiblement hermétiquement indépendantes. Thus, the portable security device capable of inflating multiple envelopes, according to the invention comprises at least one surrounding air inlet, at least one inflation means, at least one enriched air or gas zone, at least one non-return valve, at least one acceleration cone connected to at least one inflatable envelope, while it comprises at least one separating wall, which compartmentalizes at least the end of at least one acceleration cone opening in at at least two substantially hermetically independent inflatable envelopes.
Selon une alternative, le dispositif comprend au moins une entrée de gaz comprimé, au moins une chambre d'admission connectant au moins une entrée d'air environnant, au moins un cône d'accélération et au moins une chambre intermédiaire à effet venturi. La chambre d'admission correspond à une zone de gaz enrichi, tandis que la/lesdite(s) chambre(s) intermédiaire(s) est/ sont localisée(s) entre au moins une entrée de gaz comprimé et au moins une chambre d'admission. According to an alternative, the device comprises at least one compressed gas inlet, at least one intake chamber connecting at least one surrounding air inlet, at least one acceleration cone and at least one venturi intermediate chamber.

Selon un mode de réalisation, la paroi séparatrice compartimente au moins une zone d'air ou de gaz enrichi à au moins l'extrémité d'au moins un cône d'accélération débouchant dans au moins deux enveloppes gonflables. According to another alternative, at least one surrounding air inlet, arranged upstream, is connected to a turbine, powered by an electrical source, while a zone located downstream of the turbine corresponds to an enriched air zone. According to one embodiment, the separating wall compartmentalizes at least one air or enriched gas zone to at least the end of at least one acceleration cone emerging in at least two inflatable envelopes.
Selon un autre mode de réalisation, la paroi séparatrice compartimente au moins l'entrée d'air environnant à au moins l'extrémité d'au moins un cône d'accélération débouchant dans au moins deux enveloppes gonflables. Selon un mode d'exécution, la paroi séparatrice compartimente au moins une partie d'au moins un cône d'accélération, d'au moins un clapet anti-retour à au moins l'extrémité d'au moins un cône d'accélération débouchant dans au moins deux enveloppes gonflables. Selon une caractéristique, au moins une paroi séparatrice forme avec la paroi intérieure d'au moins un cône d'accélération, des conduits fermés à l'une de leurs extrémités par au moins un clapet anti-retour et à leurs autres extrémités, connectés chacun à une enveloppe gonflable.

According to one embodiment, the separating wall compartmentalizes at least a portion of at least one acceleration cone, at least one nonreturn valve at least the end of at least one accelerating cone opening in at least two inflatable envelopes. According to one characteristic, at least one dividing wall forms with the inner wall of at least one acceleration cone, conduits closed at one of their ends by at least one non-return valve and at their other ends, each connected to an inflatable envelope.
Selon un mode de réalisation, au moins un clapet anti-retour est localisé au niveau de l'entrée d'air environnant. According to one embodiment, at least one non-return valve is located at the level of the surrounding air inlet.
Selon un autre mode de réalisation, au moins un clapet anti-retour est localisé au niveau de l'extrémité d'au moins un cône d'accélération débouchant dans au moins deux enveloppes gonflables. According to another embodiment, at least one nonreturn valve is located at the end of at least one acceleration cone opening into at least two inflatable envelopes.

Selon un mode d'exécution, au moins un cône d'accélération a une extrémité qui comprend de multiples ouvertures aptes à coopérer avec de multiples enveloppes gonflables. D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs. According to one embodiment, at least one acceleration cone has an end that comprises multiple openings capable of cooperating with multiple inflatable envelopes.
