Definitions

  • the invention relates to an emergency exit device for a motor vehicle according to the preamble of claim 1.
  • a generic, known emergency exit device for a motor vehicle (EP 0 433 940 A1) comprises a pyrotechnic device on a, a vehicle door with a body connecting connecting member and an ignition control unit for the pyrotechnic device, said after ignition, the connecting member is deformed or destroyed by the pyrotechnic unit so far that the connection between the vehicle door and body is separated.
  • a blasting element in the door hinge pin of the vehicle door is arranged here as pyrotechnic device.
  • the door bolts are withdrawn from their bolt receptacles on the body, so that the hinge connection is released.
  • a force acting on the motor vehicle door to open the emergency exit is not applied, so that the door must be pressed by a person to the outside, which in particular in case of significant accidental deformations is cumbersome or may not be performed.
  • an emergency exit device for a motor vehicle is known (DE 37 35 133 C2), in which an explosive belt is arranged between the edge region of the front or rear window and the associated vehicle outer cover frame. By igniting the explosive band of the vehicle outer cover frame is pressed or blasted, whereupon then the opening of the emergency exit, the disc must be pressed to the outside. This may be cumbersome or not possible, especially in the case of severe vehicle deformations such as in the case of the above emergency exit devices.
  • JP 02034452 A shows a vehicle door, which is pivotally hinged to a body-side column by means of a hinge.
  • the hinge has a first hinge part and a second hinge part, the are pivotally connected to each other by means of a hinge pin.
  • the first hinge part is attached to the column by means of screws and weld nuts.
  • the second hinge part is fixed to the vehicle door by means of screws and weld nuts.
  • the welding nuts are associated with explosives, which are directed with their ends transversely to the weld nuts of the hinge screws. After igniting the explosives, a thinner wall area formed in the column wall should be destroyed here so that the vehicle door can fall off.
  • an emergency exit device for a railway wagon in which a designated as a cover plate, not to be opened window pane for an emergency exit pyrotechnic blasted and removed.
  • This window pane is connected by means of a fastening element with the body of the railway wagon, wherein in the interior of the fastening element, a compressed gas generator is mounted.
  • the fastener Upon activation of the compressed gas generator, the fastener is destroyed at a predetermined breaking point by the resulting gas pressure and the gas pressure spreads in a surrounding cavity formed by a ring member made of elastomeric material, whereby the window pane is pushed out of a seal from the window opening.
  • the object of the invention is therefore to provide an emergency exit device for a motor vehicle door, by means of the disconnected connection between the vehicle door and body, a secure emergency exit opening is provided.
  • a force component directed approximately transversely to the door plane of the closed vehicle door and the vehicle exterior can be applied to the vehicle door
  • Vehicle outside directed force component on the vehicle door by means of an integrated in the connecting member, pyrotechnic actuated cylinder / piston unit can be applied.
  • vehicle door should also be understood to mean all the flaps and covers of a vehicle which, when opened, allow access to the vehicle interior.
  • the ignition control unit can be activated via a crash sensor. This ensures that the emergency exit device is automatically activated in relevant crash situations and is not triggered by an occupant manually via a key switch. This ensures access to the vehicle interior, if necessary for rescue personnel in any case.
  • a control is preferably suitable for conventional production vehicles, where unlike armored security vehicles, it is not important to protect occupants from exposure to protect the outside, but in an accident to ensure unimpeded access for rescue personnel to the vehicle interior.
  • a crash sensor can For this purpose, an existing anyway in the vehicle airbag sensor may be used.
  • the activation of the ignition control unit via a crash sensor is also claimed in connection with a generic emergency exit device.
  • a first pyrotechnic device which is provided for the connection separation, should possibly be ignitable in front of a second pyrotechnic device, which applies the force component in the opening direction of the emergency exit. If only one pyrotechnic device is used, it is also possible to provide a step generator, with the ignition of the first stage enabling the connection separation and the ignition of the second step the force component in the opening direction. With these measures, the opening security is further increased.
  • the pyrotechnic device may be mounted in the region of a hinge arrangement.
  • a hinge arrangement for example, known per se hinge bolts in conjunction with a second pyrotechnic device for applying the opening force component can be used.
  • a single pyrotechnic device per hinge which comprises a piston which is zubewegbar transversely to a shear-off hinge pin.
  • the opening force component should be transferable to the vehicle door by means of the same piston.
  • the hinge pin is received in an end-side hinge eye of a door-side hinge part and a guide rail as a body-side hinge part in a concrete, simple and compact construction embodiment.
  • the guide rail for guiding the hinge eye is directed to the vehicle outside.
  • the piston for shearing the hinge pin engages after ignition of the pyrotechnics on the hinge eye on such that the hinge pin is sheared off first and then the hinge eye in the guide rail to the vehicle outside and thus the connected to the hinge eye vehicle door is pressed in the opening direction.
  • the entire pyrotechnic device including the necessary guides is advantageously accommodated in a hinge component, which can be mounted in particular as an option to a conventional hinge component.
  • the pyrotechnic device is mounted in the region of a door lock.
  • a kausauftrennung done with relatively little force, so that required explosive charges are advantageously small dimensions.
  • Such an arrangement of the pyrotechnic device in the door lock area can be arranged both as an alternative to a pyrotechnic device in the hinge area or optionally also in addition.
  • a preferred, concrete embodiment of this is proposed with the features of claim 9.

  • the lock base plate contains an open to the vehicle outside guide profile.
  • a Schokeilitational absprengbaren Explosive bolt fixed as the first pyrotechnic device.
  • a cylinder recess of the door wedge support a pyrotechnically activatable and supported to the vehicle outside on the lock base plate piston is included as a second pyrotechnic device.
  • the explosive bolt is first activated to disconnect the connection, and then the door key carrier is pressed towards the vehicle outside by means of the controlled piston. Since the closed vehicle door is connected to the door wedge carrier via the door wedge, the vehicle door is also pressed open in the opening direction.
  • a conventional screw can be used instead of a blast screw when the piston force is sufficient to shear off by a movement of the door wedge carrier the bolt.
  • a lock base plate and a retractable and fixable door wedge support can advantageously be optionally carried out an arrangement with a conventional door wedge support without pyrotechnics or pyrotechnically activated door wedge support.
  • the door wedge is held according to claim 11 adjustable in the usual manner on the door wedge carrier.
  • an emergency exit device on a vehicle, for example on a driver-side vehicle door.
  • a plurality of emergency exit devices can also be provided, which are then preferably attached to opposite sides of the vehicle should be to ensure an exit of inmates as well as access by rescue personnel even in unfavorable vehicle situations.

  • the guide rail 9 is directed to guide the hinge eye 7 to the vehicle outer side 10.
  • the pyrotechnic device 2 comprises a pyrotechnic transversely to the hinge eye 7 and thus on the hinge pin 6 zubewegbaren piston 11th
  • predetermined breaking points 12, 13 are formed on the hinge pin 6.
  • the pyrotechnic device 2 is coupled to an ignition control unit, which is not shown here, however.
  • This ignition control unit can be activated for an emergency exit device, for example via a crash sensor.
