Title
(DE) FAHRZEUGINSASSENRÜCKHALTESYSTEM
(EN) VEHICLE OCCUPANT RESTRAINING SYSTEM
(FR) SYSTÈME DE RETENUE D'OCCUPANT DE VÉHICULE
Abstract
(DE) Ein Fahrzeuginsassenrückhaltesystem (10) umfasst einen Fahrzeugsitz (12), der eine Rückenlehne (14) mit einer Sitzlehnenfläche (24) aufweist und ein in den Fahrzeugsitz (12) integriertes Gassackmodul (16), das einen Gassack (18) aufweist, der im aufgeblasenen Zustand in einer horizontalen Schnittebene L-förmig ist. Der Gassack (18) hat einen einen ersten Schenkel des L bildenden befüllbaren Auffangabschnitt (20), der entlang einer Sitzlängsrichtung (L) mit Abstand zur Sitzlehnenfläche (24) positioniert ist und einen einen zweiten Schenkel des L bildenden befüllbaren Verbindungsabschnitt (22), der den Auffangabschnitt (20) mit dem Fahrzeugsitz (12) verbindet. Der Gassack (18) weist wenigstens ein Stabilisierungselement (46) auf, das einer von der Sitzlehnenfläche (24) weg gerichteten Kraft (F) auf den Auffangabschnitt (20) entgegenwirkt, wenn der Fahrzeuginsasse auf eine Prallfläche (30) auftrifft, um den Auffangabschnitt (20) gegenüber dem Verbindungsabschnitt (22) zu stabilisieren.
(EN) The invention relates to a vehicle occupant restraining system (10) comprising a vehicle seat (12), which has a backrest (14) with a seat rest surface (24), and an airbag module (16), which is integrated into the vehicle seat (12) and has an airbag (18) that is L-shaped on a horizontal sectional plane in the inflated state. The airbag (18) has a fillable catching section (20), which forms a first limb of the L and which is positioned at a distance from the seat rest surface (24) along a seat longitudinal direction (L), and a fillable connecting section (22), which forms a second limb of the L and which connects the catching section (20) to the vehicle seat (12). The airbag (18) has at least one stabilizing element (46) which counteracts a force (F) that is directed away from the seat rest surface (24) and acts on the catching section (20) in order to stabilize the catching section (20) relative to the connecting section (22) when the vehicle occupant strikes an impact surface (30) .
(FR) L’invention concerne un système de retenue d'occupant de véhicule (10) comprenant un siège de véhicule (12) pourvu d’un dossier (14) présentant une surface de dossier (24), ainsi qu’un module de coussin gonflable (16) qui est intégré dans le siège de véhicule (12) et comprend un coussin gonflable (18) présentant à l'état gonflé une forme de L dans un plan de coupe horizontal. Le coussin gonflable (18) présente une partie de retenue (20) gonflable formant une première branche du L, positionnée le long d'une direction longitudinale de siège (L) à une certaine distance de la surface de dossier (24), ainsi qu’une partie de liaison (22) gonflable formant une seconde branche du L, reliant la partie de retenue (20) au siège de véhicule (12). Le coussin gonflable (18) présente au moins un élément de stabilisation (46) qui va à l’encontre d’une force (F) orientée à l’opposé de la surface de dossier (24) et exercée sur la partie de retenue (20) lorsque l'occupant du véhicule heurte une surface d'impact (30), afin de stabiliser la partie de retenue (20) par rapport à la partie de liaison (22).
