Definitions
- the invention relates to an airbag having the features of claim 1 and a use of the airbag having the features of claim 18.
- Leakage openings on an airbag which in the event of an accident in particular to protect an occupant of a motor vehicle from injury, serve the controlled gas outlet with respect to the amount of gas per unit of time. This achieves a defined damping of the impact acting on the motor vehicle.
- the hot gas flows very concentratedly at high speed through these openings. Also exists the
- the gas bag has 30 to 250 outlet openings. Further advantageous embodiments have 40 to 140, in particular 40 to 100 outlet openings.
- the at least five outlet openings each have a diameter between 2 and 8 mm, in particular diameter of 5 to 7 mm.
- the at least five outlet openings have a substantially circular circumference. It is advantageous, but not mandatory, that at least a part or even all of the outlet openings have the same diameter.
- rectangular, square and / or polygonal outlet openings may also be used in at least part of the outlet openings.
- outlet openings have the same shape.
- the total area of the at least five outlet openings is between 0.15 and 0.6 cm 2 , in particular between 0.19 and 0.5 cm 2 .
- the total area of the outlet openings according to the invention may be 10% larger or smaller than the total area of the known outlet openings, since the gas dynamics: and the expansion of the optional non-recessed / reinforced edges of the Outlet openings and recessed / reinforced edges of the outlet openings must be taken into account.
- the at least five outlet openings are arranged uniformly in partial regions of the envelope, which faces away from an occupant.
- a targeted outflow can take place if the at least five outlet openings are arranged at least in two groups on the envelope. Thus, a targeted control of the outflowing gas can be achieved.
- the area of the steering wheel spokes and / or the area covered by the flaps of the airbag cap are free of outlet openings.
- a further advantageous embodiment is that at least a part of the outlet openings is arranged on the casing as a function of the unfolding of the casing.
- the object is also achieved by using an airbag in a steering wheel, a side airbag system, a passenger Airbag system, a head-curtain and / or an airbag system dissolved in a seat.
- Fig. 1 is a view of an airbag with a shell
- FIG. 2 shows a further view of the gas bag according to FIG. 1;
- Fig. 3 is a schematic side view of a steering wheel with a deployed airbag
- 4 to 6 are schematic representations of differently shaped outlet openings
- Fig. 7 is a schematic representation of a shell with groups of outlet openings.
- Fig. 1 shows the back of a deployed gas bag with a shell 10 without connected units.
- the basic structure of a gas bag together with the units is known, so that can be dispensed with a description here.
- Rear side prevents direct emission of hot gases to a vehicle occupant.
- FIG. 2 shows a total of 51 outlet openings 1 in a total of four groups 2.
- the groups 2 may each have an identical number of outlet openings 1 or a different number.
- the groups are arranged so that the outlet openings 1 are within the steering wheel rim, not shown here, when the shell 10 is deployed.
- Fig. 3 is a schematic side view of a gas bag 100 is shown with a shell in the deployed state. It is indicated by arrows where the outlet openings 1 are, namely on the side facing away from the vehicle occupant.
- a steering wheel airbag is shown.
- similar arrangements can also be made for passenger airbags or side airbags.
- FIGS. 4 to 6 schematically show groups 2 of outlet openings 1, each having different shapes.
- the outlet openings have a triangular circumference, in FIG. 5 a square circumference and in FIG. 6 a round circumference.
- FIG. 7 shows that groups 2 of outlet openings can also be arranged over a larger area of the envelope 10.
