Definitions

  • the present invention relates to a motor vehicle with an airbag device which can be moved on a motor vehicle roof.
  • Airbag devices located in the roof area of motor vehicles are widely known from the prior art. They serve to reduce or even avoid possible injuries to a vehicle occupant as a result of at least one part of the body colliding with an airbag filled with a gas.
  • a gas bag emptied during an accident-free operation (the state of which is to be referred to as the first operating state in the following) is acted upon by a gas generator with a gas within milliseconds until the gas assumes a gas-filled state (which will be referred to as the second operating state in the following).
  • These known airbag devices are fastened in the roof area of the motor vehicles, which guarantees that the gas-filled airbag is not always optimally positioned relative to a motor vehicle occupant.
  • the motor vehicle initially has a roof and at least one seat that can be moved in a vehicle interior for a vehicle occupant. Furthermore, at least one receptacle provided with at least one airbag device is movably mounted on the roof.
  • the receptacle is set up in such a way that its position in relation to the seat is essentially constant in space. So if the seat moves in the motor vehicle, the seat will be added. Alternatively or cumulatively, it can be provided that the recording also follows a movement of a component of the seat, in particular the seat back. This advantageously creates a motor vehicle in which the relative position of the seat and airbag device remains essentially constant, even when the seat and / or one of its components is moving.
  • the type of movement of the seat and / or its component or the receptacle is not restricted according to the invention. Rather, the seat and / or its component or the receptacle can move translationally and / or rotationally in any spatial direction.
  • At least one first drive means located on the roof and / or on the receptacle and at least one second drive means located on the seat are provided in the motor vehicle, each with on-board electronics located in the motor vehicle are connected. This advantageously creates a coordinated and automated movement of the seat and the receptacle.
  • a visually appealing design of the motor vehicle according to the invention is created if the receiving means extends over the width of the roof or a part thereof.
  • the receptacle can only be used to accommodate the airbag device. However, it can also advantageously perform other useful and helpful functions for a vehicle occupant if the receptacle has a display, a sun visor, a receptacle for accommodating objects, for example glasses, and / or a lamp.
  • the airbag device has at least one tether that extends outside an airbag and is operatively connected to it. In this way, it is advantageously possible in a simple manner to generate a desired geometry of the gas bag filled with gas.
  • the airbag device itself comprises at least one gas bag. This can advantageously be made in one piece or, if it is made in several parts, can have gas-bag sections that are connected to one another in a material-to-material, non-positive or positive manner.
  • the gas required for the previously disclosed gas bag or gas bag sections is advantageously generated by at least one gas generator known per se, which can be designed as a pyrotechnic gas generator, cold gas generator or hybrid gas generator.
  • the gas generator, part of the Gas generators or all gas generators are operatively connected to the gas bag in that they are wholly or partially accommodated in it or the gas bag sections or in that they are connected to the gas bag or gas bag sections via gas guide means, in particular hoses.
  • a gas generator is triggered on the basis of at least one crash sensor which is known per se and is operatively connected to on-board electronics of the motor vehicle which are also known per se.
  • the gas bag provided according to the invention or the gas bag sections themselves can be made of any suitable material.
  • This material is particularly preferably a polyamide or a polyethylene terephthalate.
  • the gas bag or the gas bag sections can advantageously have at least one gas outlet means, through which the gas can escape after a defined period of time from the airbag device according to the invention, which is inflated in an accident situation.
  • the gas outlet means can in particular be designed as an outlet valve and / or in the form of defined openings in the outer skin of the respective gas bag section through which the gas exits peu-à-peu.
  • part of a motor vehicle 1 according to the invention is shown in a schematic side view. Specifically, an upper part of a motor vehicle 1 with a windshield 5 and a roof 10 is shown, which delimit part of a motor vehicle interior 15.
  • the seat 30 In the motor vehicle interior 15 there is a partially shown seat 30, having a seat back 20 and a headrest 25, which is shown in the figure in two positions: in a first position, which is drawn in the figure on the left with dashed lines and represents a starting position , and in a position representing an end position, which is drawn on the right with solid lines.
  • the figure therefore shows how a vehicle occupant, not shown here, has moved the seat 30 from an area adjacent to the windshield 5 into an area further away from the latter.
  • the seat 30 is provided with a drive means 35 which is operatively connected to an on-board electronics 40 known per se (cf. double arrow I).
  • a receptacle 50 mounted on the roof 10 by means of a drive means 45 is shown (cf. double arrow S), on which an airbag device 55 and a display 60, for example an LCD screen, are accommodated.
  • the drive means 45 and the airbag device 55 are operatively connected to the on-board electronics 40 (cf. double arrows II and III).
  • a movement of the receptacle 50 in accordance with the travel path S takes place along a rail 65 arranged on the roof 10.
  • This movement takes place in proportion to a movement of the seat 30: if the seat 30 is moved from left to right, as shown by way of example in the figure, the receptacle 50 also moves accordingly from left to right, the relative position of the seat 30 and the receptacle 50 remaining essentially constant or being maintained.
  • the airbag device 55 In the starting position shown on the left in the figure, the airbag device 55 is in an accident-free state, ie the airbag 70 present in the airbag device is emptied of gas.
  • the airbag device 55 is shown in an accident situation in which the gas bag 70 is filled with gas by a gas generator (not shown in each case).
  • the desired geometry of the gas bag 70 is supported by tether 75 arranged on the outside thereof. It is easy to see that the relative positional stability of the seat 30 and the receptacle 50 in an accident-free as well as an accident-prone situation is associated with an advantageous positioning of the gas bag 70 in the event of an accident.
