Description

[0001] The invention relates to an airbag for a vehicle according to the preamble of claim 1. Furthermore, the invention relates to a vehicle with at least one such airbag.

[0002] In the event of an accident, rescue conditions for emergency services are becoming increasingly difficult. Occupant protection is further improved by multiple airbags, each with its own airbag cover, and by passenger cells that are becoming ever safer through the use of high-strength steels and composite materials. However, in extreme accidents, this makes it significantly more difficult to make rescue cuts, for example, in a roof pillar of the vehicle body, in order to extricate an occupant. Although rescue data sheets exist for every vehicle, which show body reinforcements, airbags, control units, batteries, seatbelt pretensioners, fuel tank, etc., not every vehicle owner carries these in the form of a rescue card. With the electrification of the vehicle fleet, entirely new challenges are emerging for both the automotive industry and emergency services.

[0003] The rescue data sheets are merely schematic, intended to provide rescue workers with simple and essential information. Not every vehicle owner keeps a rescue card in their vehicle. Even within a single vehicle series, there are differences in the placement of body reinforcements between individual models. This complexity is not adequately addressed. Vehicles are increasingly using more robust materials, and responding to these changes is usually left to the rescue workers. When rescue workers arrive at the scene of an accident, they sometimes have to search for the rescue data sheets, wasting valuable time.

[0004] From EP 1 652 898 A2 a permanent marking for the permanent identification of painted surfaces is known, wherein the marking is invisible in daylight and only becomes visible through irradiation with UV light.

[0005] From DE 20 2005 000 818 U1, a gasbag for a vehicle occupant restraint device is known, comprising a gasbag wall formed from at least one fabric part and an electrically controllable device arranged on the gasbag wall. The gasbag further comprises an electrical conductor, and the fabric part and the electrical conductor form a pre-assembled unit.

[0006] From DE 42 36 783 A1, an airbag for a driver's seat is known, which is manufactured in the form of a pocket-shaped body from a cut fabric section and a cut fabric section. A label is attached to the airbag by simultaneously sewing the label and the cut fabric sections, with the label being held lengthwise between the cut fabric sections on one side. Part organization information, such as the manufacturer's name, product name, and test number, is pre-printed on the label as a barcode. The label is sewn onto the airbag in such a way that the barcode is visible from the outside after the airbag is completed.

[0007] From FR 2 959 466 A1, a generic airbag for a vehicle and a generic vehicle with at least one roof rail and such an airbag are known. The airbag comprises an airbag cover on the outside of which at least one written rescue instruction is applied, wherein the at least one written rescue instruction is applied to the outside of the airbag cover in such a way that the at least one written rescue instruction is legible from outside the vehicle when the airbag cover is deployed. The airbag is designed as a head airbag, which, when deployed, is located in the area of ​​the side windows of the vehicle.

[0008] The invention is based on the objective of providing an airbag for a vehicle and a corresponding vehicle with at least one such airbag, which, after its deployment in an accident, enables faster rescue of the occupants.

[0009] This problem is solved by an airbag for a vehicle with the features of claim 1 and by a vehicle with the features of claim 5. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims.

[0010] To provide a vehicle airbag that facilitates faster occupant rescue after deployment in an accident, at least one rescue warning is affixed to the outer surface of the airbag casing. This warning is positioned so that it is visible from outside the vehicle when the airbag is deployed. Furthermore, the airbag is a head airbag, which, when deployed, is located near the vehicle's side windows. This means that the deployed head airbag hangs at the level of the side windows, ensuring that the rescue warnings are clearly visible to emergency responders.The at least one rescue indicator affixed to the airbag cover of the head airbag includes at least one display that, when the head airbag is deployed, indicates the position of a corresponding potential rescue cut on the roof rail. This display can be, for example, an arrow or an LED. The tip of the arrow can point to the corresponding potential rescue cut, and the LED can be positioned in line with the corresponding potential rescue cut. Since vehicles can have different drive systems, body reinforcements, equipment levels, etc., various optimal positions for potential rescue cuts may result.These optimal positions for potential rescue cuts can be clearly and prominently displayed to rescue personnel by the vehicle manufacturer via at least one indicator, thus preventing or at least reducing errors in cutting. Furthermore, the rescue cuts can be made more precisely, effectively, quickly, and safely for the rescue personnel.

[0011] In an accident, the vehicle's airbags deploy. Applying rescue instructions to the airbag casing clearly and visibly conveys important information to rescue workers regarding the extrication of the occupants. This can save valuable time during the rescue operation.

[0012] Furthermore, a vehicle with at least one roof rail and at least one such airbag is proposed.

[0013] In an advantageous embodiment of the airbag, the at least one rescue instruction can include special hazard warnings and / or recovery instructions and / or a data sheet number from an associated vehicle rescue data sheet and / or a code from the associated vehicle rescue data sheet that can be read by a reader and / or information about the locations of potential rescue cuts on the vehicle and / or correspond to the vehicle's rescue data sheet. The special hazard warnings and / or recovery instructions can, for example, include the locations of body reinforcements, airbags, control units, batteries, seat belt tensioners, fuel tanks, etc. Particularly in the case of an electric vehicle, important information about the location of high-current cables can help prevent injuries to rescue personnel during the recovery operation.The specified data sheet number of the corresponding rescue data sheet for the vehicle allows rescue services to quickly research and locate the relevant data sheet. Furthermore, the code, readable by a scanner, can be applied to the airbag, for example, as a QR code or barcode. This allows rescue services to automatically be shown the rescue data sheet for the vehicle associated with the scanned code. If at least one rescue instruction corresponds to the vehicle's rescue data sheet, then every vehicle owner automatically carries the rescue data sheet in the vehicle.

[0014] For example, at least one rescue instruction can be printed directly onto the outside of the airbag cover. Additionally or alternatively, a data sheet containing at least one rescue instruction can be affixed to the outside of the airbag cover. By making rescue instructions visible on the outside of the airbag cover, rescue workers can quickly grasp important information for extricating the occupants and take it into account during the rescue operation.

[0015] In an advantageous embodiment of the vehicle, at least one marking, invisible under normal light, can be applied to the roof rail, indicating the position and course of a potential rescue cut. This marking can be made visible when illuminated with a special light. Such a marking can, for example, be implemented using a fluorescent paint that can be made visible at the accident scene by UV light. In this embodiment, the at least one rescue indicator includes a statement that corresponding markings are present on the roof rail. The clear indication of the positions where rescue cuts should be made for the greatest chance of success makes the work of the rescue personnel simpler and safer.

[0016] The features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the figure description and / or shown in the figures alone, can be used not only in the combinations specified, but also in other combinations or on their own, without departing from the scope of the invention.
