Definitions
- the invention relates to a side impact protection device for passengers in a motor vehicle with at least one inflatable airbag arranged in the folded state behind at least one A-pillar covering.
- Such a side impact protection device is known from DE 29605 897.
- an airbag or airbag is fixed in its position in a plastic sleeve and is arranged behind a cladding in the area of an A-pillar and a roof frame.
- the airbag is connected at one end to a gas generator and, when inflated, extends over a lateral area in the vehicle, in particular to protect a passenger's head from injury.
- the object of the application is to provide a sufficiently stable covering and, at the same time, to allow the airbag to emerge freely to protect a passenger.
- the A-pillar cladding is made of a primarily rigid material and has a pivot line running essentially in the longitudinal direction of the A-pillar around which at least one cladding section of the A- Column cladding for releasing an outlet gap for the airbag can be pivoted relative to the A-pillar in the direction of the passenger compartment.
- the rigid A-pillar trim ensures a certain level of protection for the passenger when it comes into contact with the A-pillar or the A-pillar trim, whereby At the same time, the airbag folded behind the A-pillar trim and its supply line and possibly the gas generator are protected from impacts or the like from the outside.
- the A-pillar trim In order to enable the airbag to emerge in an emergency in a simple and safe manner in spite of the use of a rigid material for the A-pillar trim, the A-pillar trim has a pivot line. Around this, when the airbag is inflated, at least one trim section of the A-pillar trim is pivoted to release an exit gap. As a result, it is not necessary that the A-pillar cover as a whole has to be detached from the A-pillar in order to allow the airbag to inflate.
- a simple manufacture of an A-pillar cladding from a rigid material results, for example, by using a mixed fiber fleece. This can be cut and shaped accordingly.
- Such a mixed fiber fleece can preferably be composed of reinforcing fibers and matrix fibers as a needled mixed fiber fleece. Different materials can be used for the different fibers. Because of the availability and recyclability, flax is used in particular for the reinforcing fiber. A preferred material for the matrix fibers due to its characteristics is polypropylene. In a preferred embodiment, the mixing ratio of the components can be 50:50 based on the weight percent.
- a decorative material can be laminated onto a visible side of the A-pillar trim in order to maintain an optically appealing surface and also to support the flexural strength.
- Such fixing devices can be arranged on a rear side of the A-pillar lining opposite the visible side.
- a simple embodiment of such a fixing device can be realized in that the fixing device is known to be formed by a clip and a retainer releasably holding it.
- These fixing devices can also serve, for example, to pivot the A-pillar trim as a whole, in this connection the pivot line running along fixing devices arranged asymmetrically to the A-pillar trim.
- these fixing devices are offset on one side with respect to a center line of the A-pillar trim running in the longitudinal direction of the A-pillar, and when the airbag is inflated, the A-pillar trim is pivoted about the fastening points between the A-pillar and the A-pillar trim.
- the cladding section which extends over the center line to the fixing devices is lifted from the A-pillar to such an extent that the airbag can emerge through the exit gap formed.
- the pivot line can run along a material weakening formed in the A-pillar cladding.
- a material weakening is a film hinge or a protrusion that preferably protrudes on a rear side of the A-pillar lining.
- a swivel line is formed by a press line separating surfaces of the A-pillar cladding that are pressed to different degrees.
- a weakly pressed covering section will pivot outwards in relation to a more pressed covering section along the pressing line when the airbag is inflated.
- differently structured or differently constructed cover sections can be used, of which one cover section can be pivoted relative to the other cover section along a corresponding pivot line when the airbag is inflated.
- a combination with the fixing devices arranged asymmetrically to the center line of the A-pillar cladding also being possible.
- the linings of the B and / or C and / or D pillar can be constructed analogously to the A pillar lining.
- passengers are protected both in the front and in the rear of the vehicle by airbags, particularly in the head area.
- an airbag exits to the front and an airbag correspondingly to the rear through a corresponding cladding of the B-pillar, in which case the B-pillar cladding has two pivotable cladding sections for the two airbags.
- an airbag in the area of the A-pillar could possibly be dispensed with.
- the A and C or D pillars are relatively strongly inclined backwards or forwards so that they merge into one another in the roof area.
- the A- and C- or D-pillar linings can be formed in one piece in analogy.
- tie-down points for the airbag can be arranged in the area of the A and C or D pillar, in particular at its lower end.
- the airbag can be connected to these guy points via tether straps, belts or the like.
- tether straps belts or the like.
- Fig. 1 is a partial schematic representation of a motor vehicle with A, B and
- FIG. 2 is a side view of an A-pillar trim
- FIG. 3 shows the A-pillar trim according to FIG. 2 with the airbag inflated
- Fig. 4 shows a section along the line IV-IV of Fig. 3 in a first
- Fig. 5 shows a section along the line IV-IV of Fig. 3 in a second
- Fig. 6 shows a section along the line IV-IV of Fig. 3 in a third
- FIG. 1 shows a partial representation of a motor vehicle 2 with a side impact protection device 1.
- This has an airbag (not shown) arranged in the area of at least one column in the folded state below the corresponding covering 3, 12, 13.
- the side impact protection device 1 comprises the corresponding cladding of the respective pillar, a side impact protection device in the area of the A pillar 3 being described in particular below.
- the side impact protection device 1 can also have corresponding airbags in the region of the B-pillar or C-pillar cladding 12, 13.
- a D-pillar with cladding that is otherwise formed in other vehicles is missing. This can also be constructed according to the A-pillar cladding.
- 2 shows a side view of an A-pillar trim 3 as it is arranged on the inside of the passenger compartment of the motor vehicle 2 on the A-pillar 3 '.
- the A-pillar trim 3 extends in the longitudinal direction 5 of the A-pillar and has an upper end 16 and a lower end 17.
- the A-pillar trim 3 is releasably attached to the A-pillar on its rear side 19.
- a folded airbag is arranged between the A-pillar trim 3 and the respective pillar, the interior of which is connected to a gas generator (not shown).
- FIG. 3 shows the A-pillar trim 3 from FIG. 2 with the airbag 4 inflated. Depending on the arrangement of the gas generator, this opens in the opening directions 18 relative to the airbag from the lower end 17 to the upper end 16 of the A-pillar trim 3 or vice versa.
- the airbag 4 When the airbag 4 is inflated, an outlet gap 8 is formed between the A-pillar trim 3 and the associated A-pillar in that a trim section 7, see the following figures, pivots inward relative to the rest of the A-pillar trim toward the passenger compartment.
- a further guy point 14 can be arranged, for example, in the area of the B-pillar cladding 12 or C-pillar cladding 13 or on the corresponding pillar.
- FIG. 4-6 each show a section along the line IV-IV from FIG. 3 for different exemplary embodiments of A-pillar linings 3.
- a pivot line 6, about which a cladding section 7 of the A-pillar cladding 3 can be pivoted inward in the direction 21 toward the passenger compartment, is determined by a projection 10 protruding from the rear side 19.
- the pivot line 6 is determined by a pressing line 11 which separates surfaces of the A-pillar cladding 3 which are pressed to different degrees from one another.
- the cladding section 7 to the left of the pressing line 11 in FIG. 5 is less compressed than the section to the right of the pressing line 11.
- the A-pillar trim 3 is pivoted as a whole by fastening points with the A-pillar as a pivot line 6.
- the fastening points are formed by fastening corresponding fixing devices 9 to the A-pillar.
- the fixing device 9 is pivoted in the direction 22 around the fastening points, as a result of which the A-pillar trim 3 as the trim section 7 pivots in the overall direction 21 to the passenger compartment.
- the fixing devices are asymmetrical to the A-pillar trim 3, i.e. are arranged on one side to a center line, not shown.
- exemplary embodiments according to the invention result, for example, when the asymmetrically arranged fixing device 9 according to FIG. 6 is combined with the exemplary embodiments according to FIG. 4 or 5.
- a film hinge can also be used to determine the pivot line 6 in the A-pillar trim 3 be formed.
- the A-pillar trim 3 is made of different materials in the trim section 7, see for example FIGS. 4 and 5, and in the remaining A-pillar trim 3.
- a preferred material is a mixed fiber fleece, for example made of reinforcing fibers and matrix fibers.
- a preferred material for the reinforcing fibers is flax and for the matrix fibers polypropylene. These are used to produce a needled mixed fiber fleece in a ratio of 50:50 based on the weight percent.
- the retainers for the detachable mounting of the clips can be formed, for example, from ABS, polyethylene or polypropylene, it being possible for these retainers to be welded or otherwise fastened to the rear of the respective column cladding.
