Definitions
- the present invention relates to a motor vehicle and in particular to the trouble-free deployment process of a pedestrian airbag and affected components in the event of an accident.
- a pedestrian airbag must deploy quickly on the windshield in the event of a collision with a pedestrian in order to dampen the impact of the pedestrian on the windscreen and to reliably minimize the risk of serious injuries.
- the pedestrian airbag is usually arranged in a pedestrian airbag module on the lower edge of a vehicle hood and the airbag deploys in the direction in front of and onto a windshield of the motor vehicle. When deployed, the airbag hits the area between the rear bonnet edge and the area of the lower one with high impact force
- Windshield which often leads to serious damage, such as breaks, on the components arranged in this area, such as
- DE 102011 101496 A1 proposes to mount a ramp on the wiper arm as a guide surface for undisturbed deployment of the airbag. This proposal has not been able to prevail because the airbag deploying considerable forces on the lower windshield area
- Windshield wipers accelerate the windshield wiper arm, which thereby hits the windshield, which creates the risk of the windshield breaking and therefore normal operation of the vehicle is no longer permitted.
- An object of the present invention is therefore to provide a motor vehicle in which both the risk of damage to the airbag and damage to the vehicle parts affected when the airbag strikes the lower pane area can be kept lower when the airbag deploys.
- the aim is achieved in that in a motor vehicle comprising a windshield and at least one pedestrian airbag module with an airbag, which can be deployed onto the windshield via a water box cover, the water box cover having at least one impact contour as a transition contour for the deployment of the airbag.
- the airbag can in particular be arranged on the lower edge of a vehicle hood or in the water tank of the vehicle.
- the water box cover comprises an impact contour as a transition contour or guide surface for the deployment of the airbag
- the airbag can be supported without being triggered on the impact contour of the water box cover Spread the fault safely and quickly onto the windshield and position it.
- the impact contour is preferably designed as a stiffening structure in order to distribute the forces exerted on the water tank cover when the airbag is deployed and thereby to withstand it without damage.
- the impact contour can thus act as a transition contour for the safe spreading of the airbag down to the windshield. In this way, a broken window can be prevented, since the transmission of the impact force of the airbag on the
- Water box cover formed a support structure which is connected to the vehicle body with at least one support arm. This brings about a reduction in the pressure forces exerted on the water tank cover by the airbag, since these forces are transmitted to the vehicle structure through the support structure and its support arms connected to the vehicle body. This reliably prevents breakage or deformation of the water tank cover. In addition, a further reduction in the impact forces on the windshield and on one on the lower windshield area is also arranged
- the support structure with the support arm is detachably connected to the impact contour of the water tank cover.
- the water tank cover and the support structure can be produced separately from one another and then either assembled into a module before installation in the vehicle or can also be installed separately into the vehicle, in particular in the water tank of the vehicle, and then connected to one another indirectly or directly detachably .
- the support structure with the support arm can also be formed in one piece on the impact contour of the water tank cover.
- the support structure with the support arm can be formed directly on the impact contour or formed together, for example in a tool, which is particularly useful if the water tank cover and
- the impact contour can typically have an impact surface which can be designed as an inclined impact contour leading up to a height over a region of the windshield wiper.
- the baffle forms a ramp-like transition contour on which the airbag, after being triggered, moves undisturbed and without damage from the pedestrian airbag module to or over the
- Wiper height at least over the front corner of the windshield wiper facing the vehicle front, can unfold undisturbed.
- the impact contour can be hat-shaped and and on the top the impact surface and on the back opposite the windshield wiper a sloping one
- Baffle support wall and an inclined ramp surface opposite the pedestrian airbag module are Baffle support wall and an inclined ramp surface opposite the pedestrian airbag module.
- a hat-shaped configuration makes it possible, for example, for the windshield wiper motor or another vehicle part to be concealed under the impact surface arranged as the top hat surface.
- the front sloping ramp surface is the pedestrian airbag module
- the rear falling and particularly preferably steeply falling impact support wall makes it possible for the impact contour and thus the impact surface to be arranged as closely as possible, that is to say as close as possible to the lower region of the windshield.
- the baffle support wall can be at a distance of between approximately (approx.) 10 mm ⁇ x ⁇ approx. 30 mm, in particular approx. 15 mm ⁇ x ⁇ approx. 25 mm, and preferably at a distance of approx. 20 ⁇ approx. Be arranged 2 mm. The shorter the distance can be selected, the smaller it can be
- Wipers can be further reduced. This enables the
- Windshield can spread.
- the impact contour can preferably have a width y in the transverse direction of the vehicle between approximately 30 mm ⁇ x ⁇ approximately 4500 mm, in particular approximately 100 mm ⁇ x ⁇ approximately 3000 mm and preferably a specific value of approximately 2000 mm +/- approximately 200 mm. This enables the impact contour with the impact surface to be targeted between approximately 30 mm ⁇ x ⁇ approximately 4500 mm, in particular approximately 100 mm ⁇ x ⁇ approximately 3000 mm and preferably a specific value of approximately 2000 mm +/- approximately 200 mm. This enables the impact contour with the impact surface to be targeted between
- Pedestrian airbag module and wipers can be arranged.
- a reinforcing structure is formed on an underside of the impact surface. This causes a stiffening of the baffle, which makes the baffle better than that of the
- the reinforcement structure is preferably a rib or honeycomb reinforcement structure.
- a reinforcement structure With such a reinforcement structure, sections with a greater wall thickness and a smaller wall thickness can result, which alternate along the impact surface or in the lateral direction of the impact surface.
- the rib-shaped or honeycomb-shaped reinforcing structure can be arranged in a vertical position, in an inclined position or in a cross position to the direction of expansion of the airbag or to the longitudinal direction of the vehicle.
- the support structure comprises at least two spaced apart support arms which are connected to the vehicle body.
- the two spaced-apart support arms are preferably mounted in the water box of the vehicle in a directly standing manner on the floor of the water box.
- Support structure on a wing element As a result, the support arm or the support arms and the wing element can first be preassembled to form a support structure module and then this preassembled support structure module can be arranged and fastened in the water tank in a single assembly step.
- the wing element is typically designed to conform to the impact surface of the water tank cover. This surface-conforming configuration of the wing element makes it possible for the wing element to be flush with the impact surface, as a result of which the transmission of the
- the support structure consists of plastic, preferably of a carbon fiber reinforced plastic or a glass fiber reinforced or aramid fiber reinforced plastic.
- plastic preferably of a carbon fiber reinforced plastic or a glass fiber reinforced or aramid fiber reinforced plastic.
