Abstract

The car has at least one window pane of safety glass in a window aperture, held at the lower edge by a holding element (bolt) (19), which can be disabled by a release device, namely a pressure-activated cylinder (24) so that the window pane will simply fall down out of the window under the force of gravity.

Description

The invention relates to a motor vehicle, in particular to a safe Unit passenger cars mentioned in the preamble of claim 1 and Art 37 resulting from DE 37 35 133 C2.

Located in the security passenger car known from this document the front or rear window made of safety glass in one drive Stable frame, the safety glass pane on the outside is covered by a detachable cover frame. This can be in a danger situation, such as B. after an accident, an attack from outside or the like Chen, be blown off so that the vehicle occupants the security person can leave the motor vehicle through the opening of the mounting frame. The Blowing off a safety glass pane from the vehicle has the disadvantage, however, that its surroundings are endangered by the cracked glass pane. Dar Furthermore, the installation of a pyrotechnic device in the vehicle is subject to the Explosives Act and thus the associated safety requirements.

The object of the invention is therefore to provide a motor vehicle which in the preamble of Pa Tent claims 1 type in such a way that the window opening in Emergency for both the vehicle occupants and the surroundings of the motor vehicle the safety glass pane is released completely safely.  

To achieve the object, the features set out in claim 1 are provided seen.

Since in the security car, the holding element in an emergency by a mechanically operated release device is brought out of holder function, the falls heavy safety glass pane only by its own weight downwards, so that the window opening advantageously completely safe, d. H. without the stake of explosives and the associated danger to the environment, is released. Because the safety glass pane falls after the hold is released elements due to their own weight in one between the outer and inner walls of the vehicle lying shaft and is thus within the vehicle. In addition, the mechanical, hydraulic, pneumatic, electrical or elect To provide a magnetically actuated release device very inexpensively has a ge low weight and is easy to operate from the vehicle interior gene.

The release device according to the invention can be fixed to one in the vehicle built or also on a security located on a window regulator glass pane are provided. It usually takes more on a window regulator wise only a single (or if necessary also several) bearing bolts through axial and / or radial displacement to be solved, causing the safety glass pane falls into the door shaft and thus the window opening for the vehicle occupants Leaving the vehicle interior is released. One provided in the door Release device is easy to maintain and can also be retrofitted. It is the release device especially when interacting with the window regulator absolutely reliable (features of claim 2).

The bearing bolt provided in the window lifter can be used by a thread moderately secured against axial displacement by a multi-thread his. For this, the release device consists of an electrical or Hydraulic motor rotary screw device through which the bearing pin if necessary, quickly brought out of the operative connection (features of the patent Proverbs 3 and 4).  

Another possibility for designing the release device is that the two corner areas of the lower edge of a safety glass pane each a carrying bolt surrounded by a horseshoe-shaped support part while driving tool structure or is rotatably mounted in the vehicle door. The lies in the Window opening safety glass on the support parts, where this in an emergency by a motor-generated angular rotation so far down be rotated that the safety glass pane due to its own weight between the Support parts can fall through. Such a release device is small Weight and can be easily retrofitted (features of the patent claims 5).

In addition, at least at the bottom of the safety glass pane a lifting cylinder operated by hydraulic fluid or compressed air is provided, through its plunger the bearing pin is pushed through or pulled out becomes. In any case, in the door interior of a security passenger car Existing armored element offers itself, on this the Hubzylin the to attach, the plunger of which is one of a door-tight intermediate part taken bearing bolt of a hydraulic cylinder of the window lifter beat. As a result, the bearing pin is pushed out of the intermediate part, so that the linkage of the hydraulic cylinder of the window lifter is canceled and thus the safety glass pane falls into the door shaft due to the action of gravity. The The arrangement of this release device can be provided in a simple manner; furthermore are the individual parts of the release device are very robust and can be accessed easily optimally maintained (features of claims 6 and 7).

Furthermore, a Bowden cable with lever transmission can also be provided on the door hen be, the bearing pin axially displaced by the Bowden cable and thus is brought out of function (features of claim 8).

One according to the feature of claim 9 directly on the bearing pin engaging and this pyrotechnic device removes when ignited not directly against the safety glass pane, because this also falls into this the door shaft and does not endanger the surroundings of the vehicle.  

Finally, the bearing bolt of the window lifter can also be electrically excitable solenoids are moved to the release position. The Lifting magnet has a low weight and can be powered by the vehicle electrical system (Merk male of claim 10).

Finally, an embodiment of the invention is that the bearing bolt on a bayonet-type device with the window regulator in ver bond stands, whereby the bearing pin is rotated by motor and by axial Dislocation is disengaged (features of claim 11).

An embodiment of the invention is shown in the drawing and is in Explained below. It shows:

1 is a vehicle door of a security passenger car,

Fig. 2 shows a section along the line II-II in Fig. 1 in a larger representation.

The vehicle door 1 shown in Fig. 1 has a best of a rising safety glass window pane 2, which is vertically displaced at its underlying edge of a Fensterhe about 3 in the directions of the double arrow a. The window pane 2 is partially surrounded by a door window frame 10 which forms a window opening 10 'with the door parapet 1 '. The window lifter 3 consists of two intersecting swivel arms 4 and 5 . Furthermore, a receiving rail 7 is attached to the lower edge of the window pane 2 , on which the upper Endab sections of the swivel arms 4 and 5 are each articulated via a bearing pin 8 . The opposite end section of the swivel arm 4 is pivotally mounted on the vehicle door 1 via a bearing pin 9 . Finally, a guide rail 11 with a U-shaped cross section is attached to the corner area of the vehicle door 1 at the bottom, in which a roller 12 provided at the bottom end section of the swivel arm 5 is located.

The window lifter 3 is actuated by a hydraulic cylinder 15 , the piston rod 16 of which is articulated via a swivel pin 6 on the swivel arm 4 , while from the bottom end face of the cylinder jacket 15 'of the hydraulic cylinder 15 a bearing bracket 17 protrudes, which has a bearing bore 18 . About this, as shown in FIG. 2, the bearing bracket 17 is rotatably mounted on a bearing pin 19 , the axially releasably inserted at its opposite end portion in a receiving bore 20 of a sheet metal, on the inner door panel 1 "and on a armor element 22 attached part 21 is. in this case, the bearing pin is secured 19 by a spring clip 23 against axial displacement. Finally, on the between the Türaußenwandung 1 '''a druckmittelbaufschlagter lifting cylinder 24 door fixed and the Türinnenwandung 1 "used armor member 22 is introduced, the follower 24' coaxially with the bearing pin 19 and to a through opening 25 provided in the inner door panel 1 ".

If, in an emergency situation - for example in the event of an attack from the outside - the vehicle occupants are forced to leave the vehicle interior through the window opening 10 ', a vehicle occupant actuates a hydraulic switching element discretely attached in the vehicle interior, expediently in the region of the door interior trim or the like, as a result of which Via the hydraulic line 26, pressure oil is fed into the lifting cylinder 24 , thereby pushing its plunger 24 'in the direction of the arrow b. As a result, the bearing pin 19 is pushed over the effect of the spring clip 23 from the receiving bore 20 and if necessary also through the through opening 25 of the intermediate part 21 in the direction of arrow b, so that the articulation of the cylinder jacket 15 'of the lifting cylinder 15 is canceled. As a result, the window pane 2 falls into the door shaft 10 ″ in the direction of arrow c due to its own weight, that is to say due to the mere effect of gravity, the window pane 2 being displaced into the area of the door parapet 1 ′ and thus the window opening 10 ′ being released, so that the vehicle occupants can pass through they can leave the vehicle interior and the roller 12 on the swivel arm 5 is pushed out of the guide rail 11 laterally.
