Title
(DE) INSASSENSCHUTZVORRICHTUNG
(EN) OCCUPANT PROTECTION DEVICE
(FR) DISPOSITIF DE PROTECTION DES OCCUPANTS
Abstract
(DE) Die Erfindung betrifft eine für ein Kraftfahrzeug (1) bestimmte Insassenschutzvorrichtung (6) mit einem Luftkissen (4, 5), welches bei einem Unfall explosionsartig mit Gas gefüllt wird. Hierdurch prallt ein Insasse (2, 3) bei einer unfallbedingten Vorverlagerung auf das bereits vollständig gefüllte Luftkissen (4, 5) auf, wodurch das Gas durch eine Abströmöffnung (8, 9) abströmt. Die Aufprallenergie wird hierdurch auf ein körperverträgliches Mass begrenzt. Um einer thermischen Belastung des Insassen (2, 3) durch austretende Expansionsgase vorzubeugen, ist die Abströmöffnung (8, 9) in einem dem Insassen (2, 3) abgewandten Bereich der Insassenschutzvorrichtung (6) angeordnet. Diese ist hierzu insbesondere im Inneren eines geschlossenen Behälters (10) angeordnet, durch den zugleich ein problemloser Einsatz in unterschiedlichen Bereichen des Kraftfahrzeuges (1) realisierbar wird.
(EN) The invention relates to an occupant protection device (6) for a motor vehicle (1), with an airbag (4, 5) which is explosively filled with gas on an accident. An occupant (2, 3) thus impacts the already fully inflated airbag (4, 5) on a forward displacement caused by an accident, whereupon the gas escapes through an escape opening (8, 9). The impact energy is thus limited to a degree which the body will survive. In order to prevent a thermal exposure of the occupants (2, 3) to escaping expansion gases, the outlet opening (8, 9) is arranged in a region of the occupant protection device (6) facing away from the occupant (2, 3). The above is thereby in particular arranged on the inside of a closed container (10), by means of which a problem-free application in various regions of the motor vehicle (1) is possible.
(FR) La présente invention concerne un dispositif de protection des occupants d'une automobile (1), comprenant un coussin gonflable de sécurité (4, 5), qui, en cas d'accident, est rempli de gaz de manière explosive. Ainsi, lors d'un déplacement vers l'avant causé par un accident, un occupant (2, 3) vient heurter le coussin gonflable (4, 5) qui est déjà complètement gonflé, le gaz s'échappant alors par un orifice d'évacuation (8, 9). L'énergie de la collision se voit ainsi limitée dans une mesure qui peut être supportée par le corps. Afin de prévenir une exposition thermique des occupants (2, 3) aux gaz d'expansion s'échappant, l'orifice d'évacuation (8, 9) est monté dans une zone du dispositif de protection des occupants (6) qui est opposée à l'occupant (2, 3). Ce dispositif de protection des occupants est notamment monté à l'intérieur d'une boîte fermée (10), qui permet de l'intégrer facilement dans diverses zones de l'automobile (1).
