Definitions

  • the invention relates to an airbag device for a motor vehicle according to the preamble of claim 1.
  • Such an airbag device comprises a body region, which can serve as a carrier of the airbag device, a first gas bag which is arranged on the body region of the motor vehicle such that it is inflatable between the body region and a collision object located outside the motor vehicle, a gas generator for releasing a to Inflating the first gas bag serving gas and a second, for the protection of a vehicle occupant inflatable airbag, which is designed and provided for arrangement in the passenger compartment of the motor vehicle.
  • sensors For triggering a known airbag device usually sensors are used, which can detect by measuring the caused by a collision accelerations of the motor vehicle, an already occurred collision with a collision object, such as another motor vehicle.
  • said sensors activate a gas generator that inflates the gas bags to protect a vehicle occupant.
  • a pre-crash sensor system can be used which detects a collision even before the collision occurs. This makes it possible to inflate the airbags of the airbag device in time before the collision and thus to bring into position. In this case, it proves to be particularly difficult to adapt the inflation of the gas bags to the requirements of the collision, because in a light and slow collision object, a gas bag must be filled with a smaller amount of gas than in a heavy and fast collision object.
  • the invention is therefore based on the problem to provide an airbag device in which the inflation of gas bags is improved.
  • the first and the second airbag by means of a gas-conductive connection is connected such that between the first and the second airbag, a gas exchange is possible.
  • the first and the second airbag are therefore preferably connected to one another such that gas can be transferred from the first airbag into the second airbag by a compression of the first airbag.
  • the collision object So meets the collision object at a moderate speed on the inflated first airbag, this is compressed and transported with a correspondingly moderate speed gas from the first airbag through the gas-conducting compound in the second airbag.
  • the gas In a violent collision of a collision object with the first airbag, ie, the collision object has a relatively high kinetic energy, the gas is pumped at a correspondingly higher speed of the first airbag through the gas-conductive compound in the second airbag.
  • the inflation behavior of the second airbag deploying in the passenger compartment thus behaves adaptively with respect to the first airbag, or in other words, the amount of gas that passes from the first airbag into the second airbag per unit of time depends on the speed and the duration of the collision-induced compression of the first airbag.
  • the compression of the first airbag is essentially determined by the mass and velocity of the collision object. So that a resistance of the first airbag to the loads occurring during a collision is as great as possible, the first airbag can be made of a particularly resistant material.
  • the first and the second airbag are connected to one another in such a way that, as a result of compression of the second airbag, gas can pass from the second airbag into the first airbag.
  • the gas-conducting connection which connects the first and the second airbag, preferably runs through a recess of the body region, on the outside of which the vehicle occupant is disposed facing away from the first airbag in the inflated state.
  • the gas-conducting compound runs in the inflated state of the first and the second airbag between a

  • the first airbag when inflated, extends along an outer side of the body region facing away from a vehicle occupant.
  • the first gas bag preferably extends over an area outside of the side body of the motor vehicle facing away from a vehicle occupant.
  • the second airbag therefore extends in the inflated state along an inside of the body region facing a vehicle occupant, wherein the second airbag preferably extends along an inner side of a vehicle door facing a vehicle occupant in the inflated state.
  • the second airbag is integrated in a folded state in a door of the motor vehicle.
  • a state of the gas bags prior to triggering of the airbag device is understood to mean a folded state of the two gas bags. It is conceivable to form tear lines on an interior lining of a vehicle door, along which the interior lining tears open when the second airbag concealed by the interior trim is inflated as a result of a collision and unfolds into the interior of the vehicle.
  • the second airbag is arranged in a folded state on a vehicle seat of the motor vehicle.
  • the second gas bag extends in the inflated state between the vehicle seat and a vehicle seat facing the inside of a lateral body region of the motor vehicle.
  • the second airbag for example, in the folded state in one of the inside of the body region side facing a seat back of a vehicle seat, such as the driver or passenger seat, be integrated.
  • the seat back provides sufficient space for accommodating the folded airbag and possibly other components of the airbag device.
  • a seat back is easily accessible, so that an assembly of the second airbag can be carried out at any time during the manufacture of the motor vehicle.
  • such a retrofitting of the motor vehicle with the airbag device according to the invention can be facilitated.
  • the gas-conducting connection which connects the first and the second airbag in a gas-conducting manner, is arranged at least partially on the vehicle seat.
  • the gas-conducting compound can, for example, extend in sections within the vehicle seat and be guided to the second airbag. In this way and manner, the gas-conductive connection is advantageously protected by a surrounding the gas-conductive connection padding of the vehicle seat.
  • the gas-conducting connection is preferably designed as a flexible hose line. This results in a simple installation of the gas-conducting compound.
  • the first gas bag is integrated in a folded state in a door of the motor vehicle.
  • cover the first gas bag which is inflated in the event of a collision on an outside of the motor vehicle facing away from the vehicle occupant, with a flat cover plate which is flush fitted into the outside of a door of the motor vehicle and in the event of activation of the air bag device the first airbag unfolding into the exterior of the motor vehicle is blasted off.
  • the first airbag is integrated in the folded state in a side sill of the motor vehicle. It is conceivable here to form tear-off lines described above on the side skirts, which are torn open as a result of activation of the airbag device by an unfolding first airbag.
  • the inflator serving for inflating the first airbag gas generator is also set up and provided for inflating the second airbag.
  • the gas generator merely serves to pre-position the second airbag, ie, the second airbag is inflated just enough by means of the gas generator that it has a cover (for example, an area of an interior trim of the motor vehicle) that directs the second airbag toward the interior of the motor vehicle covered, pierced.
  • the cover weak points (eg tear lines), along which the cover ruptures when the expands during inflation second airbag presses against the cover.
  • the gas generator is designed to completely inflate the second airbag.

  • This can be designed to be controllable, ie, by means of the gas flow distributor, it is possible to set the introduced into the first and second airbag gas amount.
  • a possible control parameter here may be a period of time during which gas is introduced into the first or second airbag via a first or second valve of the gas flow distributor. The length of the time span can be determined by means of suitable electronics as a function of occupant and / or motor vehicle-specific parameters (occupant weight and size, vehicle speed, vehicle deceleration, etc.).
  • a further gas generator is additionally provided for inflating the second airbag, so that the two airbags can be inflated independently by means of separate gas generators.
  • the additional airbag serves only for pre-positioning of the second airbag.
  • the further gas generator can also be set up for completely inflating the second airbag. In this case, the gas-conducting connection between the two gas bags ensures that a pressure loss of the second airbag can be compensated (for example, by damage or by cooling of the gas in the gas bag).
  • the gas generators may be pyrotechnic gas generators, cold gas generators or a combination of the above types (hybrid generators). Since cold gas generators provide a comparatively smaller volume of gas compared to pyrotechnic gas generators (or hybrid generators), they are used in particular when the gas bag to be filled (for example the second gas bag in the interior of the motor vehicle) is initially merely prepositioned, ie not yet completely inflated.
  • the airbag device is coupled to a pre-crash sensor system, by means of which a collision of a collision object with the motor vehicle can be detected.
  • the pre-crash sensor makes it possible in particular to detect the collision in time. Timely means here that the period between detection of the collision and the collision itself is greater than the time required to completely inflate the airbags gas bags.

  • the pre-crash sensor system is provided and configured to detect an imminent collision with a collision object in time and to control at least one known gas generator such that the first gas bag by means of the gas generator before the arrival of the collision object completely between the collision object and the the collision-affected body area is inflated.
  • the first gas bag by means of the gas generator before the arrival of the collision object completely between the collision object and the the collision-affected body area is inflated.
  • the pre-crash sensor system activates the airbag device such that the first airbag is completely inflated and the second airbag is at least partially inflated prior to a collision with the collision object.
  • the fact that the second airbag is at least partially inflated before the collision means in this case that the amount of gas required by the second airbag to blow off the airbag covering the second airbag or to rupture the above-described tear lines is supplied to the second airbag before the collision , The breaking off or tearing takes place here by the increase in volume of the second airbag as a result of the introduction of said amount of gas.
  • the second airbag is therefore only pre-positioned here.
  • the complete inflation of the second airbag is done by means of displaced from the first airbag due to the collision gas. But it is also possible that the second airbag is inflated as well as the first airbag completely before the collision.
  • a quantity of gas which can be diverted from the first to the second airbag serves, in particular, to improve the pressure resistance of the second airbag. That is, the second airbag is damaged as a result of collision, for example by debris, a gas loss of the second airbag during the collision compensated by a collision-induced compression of the first airbag, since by compression of the first airbag gas from the first airbag in the second airbag is pumped.
  • the first gas bag has at least one first overload valve, by means of which gas can escape from the first gas bag when a threshold pressure value is reached.
  • the second airbag has at least one second overload valve, through which gas can escape from the second airbag when a threshold pressure value is reached.
  • a threshold pressure value is understood to be a value for the gas pressure prevailing in an airbag, in which case an overload valve of the relevant airbag opens.

  • the gas-conductive connection has a check valve which prevents gas reflux from the second into the first gas bag.
  • D. h. In a collision-induced compression of the first airbag, the gas displaced from the first airbag passes through the check valve via the gas-conductive compound in the second airbag and inflates this airbag. If the second gas bag is in turn subjected to collision-induced compression, for example by a vehicle occupant striking the second airbag, the check valve is activated, so that no gas reflux from the second airbag into the first airbag is possible.
