Definitions
- the invention relates to a restraint system, in particular for a motor vehicle, according to the preamble of patent claim 1.
- Such a restraint system can already be seen, for example, from DE 10 2007 052 246 A1 or from DE 10 2007 022 925 A1 as known.
- a restraint system in the form of an airbag which comprises a support structure which can be moved from a storage position to a retention position.
- Support structure is in particular formed from a plurality of flexible
- Tubular elements which are correspondingly filled with an accidental release with a medium and thus unfolded or enlarged.
- An envelope which is arranged on the outside or inside of the support structure or fills individual compartments between the individual tube elements of the support structure, thereby unfold during transfer of the support structure from the storage position to the retention position and surrounds a retention volume.
- at least one ventilation opening is provided within the enclosure, via which a medium, in particular ambient air, can be flowed into the enclosure when moving into the retention position.
- Object of the present invention is therefore to provide a restraint system of the type mentioned, in which the given by the enclosure
- Ambient air is to be supplied.
- the at least one ventilation opening is provided within a support structure and the enclosure in the storage position at least partially accommodating housing.
- at least one, and preferably a plurality of ventilation openings are provided, which are incorporated in the housing accommodating the enclosure and the support structure.
- ventilation openings can be integrated particularly favorably into the housing of the restraint system in order to prevent as far as possible a considerable negative pressure during the generation of the retention volume which is surrounded by the enclosure and thus to ensure a quick setting up of the restraint system or of the airbag.
- the enclosure is designed to be open in the region of the housing, wherein the housing forms the enclosure in regions.
- the medium in particular the ambient air, flow through the housing in the enclosure or in the retention volume.
- the enclosure is formed closed in the region of the housing and consequently has at least one ventilation opening which leads to one or more ventilation openings within the housing of the
- Fig. 1 is a fragmentary front view of a housing of a restraint system for a motor vehicle, within which a support structure and a cover are at least partially receivable, wherein the support structure and the enclosure are shown here in a retaining position, in which the restraint system in an accidental release of a Storage position is movable, wherein the housing comprises at least one ventilation opening, via which a limited by the enclosure retention volume when moving from the storage position to the retaining position with a medium, in particular with ambient air, can be supplied;
- Fig. 2a is a schematic sectional view of the restraint system with the housing, the support structure and the envelope along the line II-II in Fig. 1, wherein the support structure and the cover during their movement in the
- FIG. 2b is a schematic sectional view through the restraint system analogous to FIG.
- the present restraint system accordingly comprises a support structure 10, which is formed by a plurality of channel or tubular hollow bodies 12, 14, which are interconnected in a further described manner.
- This support structure 10 is - as can be seen from DE 10 2007 052 246 A1 - from a storage position into a Retention movable, namely after the release, for example, as a result of an impending or ongoing collision of the motor vehicle.
- the movement of the support structure 10 takes place in the present case, characterized in that the hollow body 12, 14 of the support structure, which are interconnected, are pyrotechnically filled with a medium in the form of a gas.
- the support structure 10 unfolds in the
- the restraint system comprises a sheath 16, by means of which one formed by the support structure 10 in its retaining position
- the wrapper 16 may be attached to the outside or inside of the support structure 10 or individual compartments of the
- the enclosure 16 defines a retention volume which serves to catch a seat occupant.
- FIGS. 2a and 2b each show a fragmentary and schematic illustration
- Fig. 2a shows it first that the housing 20 is substantially rectangular or box-shaped - and in the direction of the enclosure 16 open - is formed.
- the housing 20 comprises a housing bottom 22 and side walls 24, which are integrally formed.
- Ventilation openings 18 are provided. Likewise, such ventilation openings 18 are presently provided in the region of the side walls 24. Furthermore, it can be seen, a fastener 26 for the support structure 10, wherein in the region of this fastener 26, which surrounds, for example, one of the hollow body 12, 14 like a clamp, a gas generator for moving the support structure 10 from the storage position can be arranged in the retention position.
- a corresponding medium in the present case ambient air can flow into a limited by the enclosure 16 or surrounding retention volume 28, a plurality of ventilation openings 30 of the enclosure 16 are provided, which correspond to the ventilation openings 18 within the housing 20.
- the ventilation openings 18 and 30 are designed such that no excessive negative pressure arises within the enclosure 16 in the region of the retention volume 28.
- the inflow of the medium in the form of ambient air through the ventilation openings 18 and 30 is indicated schematically by an arrow 32.
- FIG. 2 b of the restraint system differs from that according to FIG. 2 a in particular in that the enclosure 16 is designed to be open in the region of the housing 20, so that the housing 20 partially surrounds the housing 20
- Serving 16 forms. With respective ends 34 defining a housing opening 36 of the enclosure 16, this is fixed to respective edges 38 of the side walls 24 of the housing 20.
- the advantage of such an embodiment is that it is possible to dispense with the ventilation openings 30 shown in FIG. 2a within the enclosure 16. So there are only the ventilation openings 18 within the housing 20th
- the housing 20 in the present case is designed so that it at least partially accommodates the support structure 10 and the enclosure 16 in the storage position. Furthermore, there is a particular advantage in that Ventilation openings 18 of the housing at least substantially outside of the overlap region with a respective hollow body 12, 14 of the support structure 10 is arranged.
