Definitions

  • the invention relates to a side impact protection device in a motor vehicle with an airbag and a gas generator, which is in fluid communication with the airbag and activated in the presence of corresponding sensor data via a control unit, wherein the airbag in a deployed state between a window cutout of a motor vehicle structure and a vehicle occupant extends and the window pane at least partially covered.
  • a side impact protection device is intended in particular for accident scenarios in which the vehicle rolls over.
  • EP 1 426 244 A1 describes a side impact protection device for a vehicle occupant, which has an upwardly deployable head airbag with a first inflator in the region of the parapet of a side structure.
  • the head airbag extends beyond the window opening of the motor vehicle structure and partially covers it.
  • a second airbag is arranged in the seat of the motor vehicle, which comprises a second inflator and extends in the thorax region of the vehicle occupant between the vehicle occupant and the vehicle side structure.
  • Such a separate formation and arrangement of the airbags was chosen in order to use the side impact protection in vehicles with different body structure.
  • a disadvantage of such a configuration are the increased installation effort and the need to hold multiple inflators or gas generators.
  • the object of the present invention is to provide an inexpensive and safe side impact protection device. According to the invention, this object is achieved by a side impact protection device having the features of claim 1. Advantageous refinements and developments of the invention are described in the subclaims.
  • the side impact protection device in a motor vehicle with an airbag and a gas generator, which is in fluid communication with the airbag and is activated by a control device in the presence of corresponding sensor data, wherein the airbag extends in a deployed state between a window cutout, a motor vehicle structure and a vehicle occupant and the window cutout at least partially covered, provides that the airbag has at least two chambers, of which the first chamber in the unfolded state partially covers the window opening and the window opening to the thorax area of the vehicle occupant and the second chamber only in the thorax area between the Vehicle occupant and the vehicle structure extends. Due to the particularly long design of the first chamber of the airbag, it is possible to provide increased rigidity in the head area, ie in front of the window opening, so that particularly effective ejection of limbs or vehicle occupants during a rollover is prevented.
  • the second chamber which is designed as a thorax airbag, arranged on the vehicle occupant side facing the first chamber, preferably sewn, glued or manufactured by appropriate weaving.
  • the first and second chambers may be fluidically connected with each other, in order to facilitate a facilitated gas flow from the preferred single gas generator.
  • the second chamber is provided with a ventilation opening, while the first chamber to provide the highest possible rigidity and long life has no ventilation opening.
  • a particularly stiff design of the airbag is achieved without this having to be hinged or hinged in the roof area. Rather, the entire airbag may extend upward and forward from a door panel or a portion of the seat back.
  • an overflow opening may be present, which closes in the course of the airbag filling.
  • a slide or a cover can be arranged, which is provided with a tether or a similar device which is attached to the airbag fabric.
  • the slider or the aperture is activated, so that in a deployed airbag, the overflow is closed by the slide or through the aperture. This prevents gas from the first chamber, which is preferably formed as gas-tight as possible, escapes into the second chamber with a ventilation opening and the rigidity and thus the safety against being thrown out of the window opening is reduced.
  • a pressure regulating valve which is closed upon reaching a certain internal pressure.
  • This pressure control valve may be formed as a spring-loaded switching valve, for example, closes the first chamber after reaching a desired pressure, for example 0.5 bar to 1 bar overpressure, said valve remains closed in the course.
  • a desired pressure for example 0.5 bar to 1 bar overpressure
  • flowing from the gas generator gas can then be discharged through another gas line into the environment or introduced into the second chamber with ventilation opening.
  • a high inflation speed of the airbag is required. Since in particular the thorax region is arranged very close to the vehicle side structure due to the structural conditions within a vehicle, it must be protected very quickly.
  • the second chamber of the airbag is formed volumetrically smaller than the first chamber, preferably, the second chamber in the thorax region is thicker than the first chamber.
  • the first chamber may extend further forward in the direction of travel than the second chamber, in particular it may completely cover the window opening in order to allow the greatest possible security against ejection of a vehicle occupant or limbs of a vehicle occupant.
  • the first chamber extends in the vertical direction beyond the window opening, that is, as far as the upper window frame or beyond. As a result, an abutment is created above the window opening, which provides additional stability.
  • a further increased stability in the first chamber can be achieved by forming vertically oriented compartments, for example tubes or other subdivisions, between which no or only minimal guest exchange is possible. These departments are arranged one behind the other in the direction of travel and extend from the thorax region or the region of the armrest of a door inner lining into the window opening or beyond.
  • the airbag may be arranged in a side trim of a motor vehicle door in a seat back, wherein in the former case, the airbag is secured in the region of an armrest in the seat trim. This will create a contact surface provided from the armrest to the parapet of the vehicle door, which the rigidity of the first chamber and the airbag benefits. Due to the substantially closed design of the first chamber, a minimum service life of 1 sec to 5 sec can be achieved at an overpressure of 0.5 bar to 1 bar. It is also provided that the second chamber can be acted upon with an overpressure of 0.1 to 0.5 bar.
