Description

Internal overpressure-absorbing brackets for vehicle front doors.

The invention relates to holding devices, the motor vehicle front doors, too still boi the highest driving speeds compared to those with open ventilation flaps and closed windows resulting in excess pressure, hold firmly pressed on their system and thereby prevent the occurrence of annoying yind noises safely and in the long term.

When driving with open ventilation flaps and closed windows occurs inside the car with the speed increasing to over 70 mm WS Excess pressure on the door window frames, especially at the front upper corners pushes outwards, makes it take off and causes annoying wind noise. the The pressure force D acting from the inside is influenced by an outside force attacking suction force S supported by the deflected by the windshield, laterally Air passing by the vehicle is generated, which acts in one direction Forces D and S can be related to one lying on the front, upper corner of the door Together, the points of application reach values of more than 10 kg, cause elastic bends and annoying wind noise as soon as the doors or window frames or turning windows are not stiff enough.

Known to avoid or at least reduce these evils are the following measures: Compact, dimensionally stable versions of the door upper parts. - Stiffeners the window frame. - Elastic door pads rel. Seals.

- Spreading of frameless dred discs. - High initial print run. - In the lower part of the door, the inclination of the frames or guide rails for the drift windows can be adjusted, for setting the contact pressure.

It has been found that elastic seals are absolutely necessary and that only compact doors (upper and lower parts made from one piece) are full correspond to the requirements to be set, on the other hand tunes with inserted in the lower part Frames or window guides are not.

The invention was based on the object, without a large amount of material easy and cheap to achieve that even light, elegant-looking door designs withstand strong attacking forces D + S without disruptive, elastic deflections and thus remain free of wind noise.

These objects have been achieved according to the invention in that the forces D + S can no longer be picked up by the doors, window frames or revolving windows.

but from those located on or in the front door pillars of the body Holder devices, behind which the front doors lay when closing, in them intervene or hook. This in a dimensionally stable body part lying Holding devices orhöhen the sealing pressure, secure a firm support and take while driving, without the doors lifting off or elastically deforming, even The largest occurring forces D + S. Even frameless turntables from Sport Coupés stay close up to the highest driving speeds and without wind noise. The pressure receiving brackets can be shaped and attached so that they are not or hardly noticeable from the outside.

EB a wide variety of designs are possible, 4 of which are in Don.

Sketches I-IV shown and then explained: Sketch I. Horizontal Section through an embodiment in which a holder 4 attached to the door pillar 5 from outside on the window frame 3 presses.

Sketch II. Horizontal section through an embodiment in which a on the window frame 3 of the door 1 attached mandrel attachment 6 in a in the door pillar 5 of the Body seated bracket 7 engages.

Sketch III. Horizontal section through an execution where a in the door spar 5 seated, resiliently sprung holding mandrel 9 in an approach 8 of the window frame 3 of door 1 engages.

Sketch IV. Side view of an embodiment in which a sports coupé a sm door spar 5 seated pressure roller 11 the frameless turntable 10 against the attacking forces D + S is supported.

The door 1 moves when it closes from its initial position shown in dashed lines into the fully drawn final position, which is shown in I-IV. It pivots it around the hinge point 2 and - (sketch I) lies behind with the window frame 3 the bracket 4 of the front body door spar 5. - (Sketch II) engages with the thorn-shaped extension 6 of the window frame 3 in the dd counter bracket 7 of 5. - (sketch III) the retaining pin 9 of 5 engages in the approach 8 (here ReBenrinne) of the penster frame 3, - (sketch IV) lies with the Lohmsnolsen turntable 10 behind the pressure roller 11 of 5.

The aforementioned counter brackets 4,7,9 and 11 press the respective existing door parts firmly against their elastic support 12, secure against Lift-off and elastic bending, absorb and prevent the attacking forces D + S the appearance of annoying wind noise.

The invention has the following essential advantages: "In all driving conditions secure support, good sealing and elimination of wind noises. Door tops can can be kept light and elegant, without the disturbing effects of what is then present Elasticity. Adjustable contact pressure, which is maintained even under the influence of D + S remain. @Aim Tür-Föfnen can act as a light switch.

Claims (1)

P a t e n t a n s p r ü c h e. Claim 1. Device on Kiz bodies, which by internal Fully absorb the forces acting on the front doors and ensure that the doors are tightly sealed, so that they are not shown e t that there are counterpressure holders on or in the front door pillar, behind which or into which the doors swing when closing. Claim 2. Devices according to claim 1, d a d u r c h g e k e n It should be noted that the pressure receptacle holders are used as cover panels in order not to be conspicuous door cut-out corners are designed for the front, upper bodywork. Claim 3. Device according to Ansorkuch 1 and 2, d a d u r c h g e it does not indicate that the pressure receptacles are in the doors or in front of them Parts engage. Claim 4. Devices according to claim 1, 2 and 3, d a d u r c h g I do not know that the doors with. corresponding approach parts in the Engage the pressure pick-up switch seated in the door pillar of the body. Claim 5. Devices according to claim 1, 2, 3 and 4, d a d u r c h It is not noted that the pressure pick-up switch is also used when the door is opened act as a light switch. L e r s e i t e
