Description

Vehicle door with height-adjustable window

The present invention relates to a vehicle door with a height-adjustable window, in particular for a car.

In most conventional vehicle doors, the narrow sides of the height-adjustable window pane are in grooves of guide rails of a

Hidden window frame. A side wall of the groove is at these

conventional guide rails inevitably over a few millimeters beyond the outsides of the windowpanes. To reduce the wind resistance, for acoustic or aesthetic reasons, it may be desirable to avoid such a projection, but the omission of the sidewall also leads to destabilization of the window pane, so that e.g. Breeze deflect the windowpane and train inside the

Passenger compartment, allow the penetration of rainfall or even solve the window glass from its anchorage.

In a known vehicle door, therefore, a hidden groove is formed on a guide rail extending in the adjustment direction of the window pane, into which a slider fastened to the window pane engages in order to block movements of the window pane in the direction of its surface normal.

This conventional structure is relatively expensive to manufacture, since the cross section of the guide rail is more complicated than that of a conventional, the edge of a window pane embracing guide rail, and because the production of the slider and its attachment to the window pane brings additional effort. Movements of the disc in the vehicle longitudinal direction are not exactly guided by the slider, so that the width of a gap between the in

Vehicle longitudinal direction front or rear narrow side of the window and an opposite leg of the guide rail may change in the course of movement of the window and may be different between front and rear narrow side. Such different gap widths are undesirable on the one hand for aesthetic reasons, on the other hand, an unnecessarily wide gap can cause exactly those acoustic or flow dynamic disadvantages that should be avoided by the transition from a slot-guided window pane to flush with the adjacent guide rail window.

An object of the present invention is a vehicle door with a

to propose height-adjustable window pane, which is easier structured and more efficient to assemble and is able to ensure an aesthetically pleasing appearance and a low-turbulence overflow regardless of the width of a gap between the window pane and guide rail.

The object is achieved according to an embodiment of the invention by the case of a vehicle door with a door body, one of the door body, at least one lateral guide rail and an upper rail limited window opening and a window, between an at least partially sunk in the door body open position and the window opening covering

Closed position is movable, wherein the window and the guide rail define a gap open to the outside of the door, an elastically pressed on a narrow side of the window outer sealing lip, the gap in a first space bounded by the sealing lip and the guide rail and its width to a Outside of the door increases, and a second space divided, which is bounded by the sealing lip and the narrow side of the window pane and whose width decreases towards the outside of the door.

The outer sealing lip can follow a change in the width of the gap to a large extent, by being more or less inclined in the gap. In any position, which can take the outer lip, turbulence by air flowing along the vehicle at best in the first subspace occur, but require due to the small cross-sectional high flow velocities and are low in audible frequency components.

The window pane may be movable between a position in which its outside is flush with an outside of the guide rail and a position in which it springs back behind the outside of the guide rail. Such a movement can arise in particular if the inside of the

Window glass rests against an elastic base of the window frame and this upsetting different degrees, depending on how big in the different positions that can take the window, the overlap with the elastic pad is. In particular, if the window pane the

Closing position leaves an overlap with the upper rail suddenly lost and trigger an inward movement of the window. The outer sealing lip should have a sufficiently large cross section to project beyond the outside of the windowpane in the recessed position.

The upper rail is preferably designed as a U-profile, which engages around an upper edge of the window pane in the closed position. Although such a U-profile can not be flush with the window pane, since inevitably a leg of the U-profile protrudes beyond the outside of the window, but this is of little importance for the aerodynamics of the vehicle and the noise because the wind at the top Rail along substantially along the longitudinal direction and therefore a step between the outside of the

Window pane and the leg of the profile hardly stimulates turbulence.

In order to simplify the structure of the door, the outer sealing lip may be part of a sealing profile extending between a narrow side and the inside of the window pane on the one hand and these opposite legs of the

Guide rail on the other hand extends.

A base of the sealing profile may be made of a stiffer material than that of the sealing lip. Such a rigid base allows anchoring of the sealing profile on the guide rail by positive locking. Base and sealing lip can be coextruded in particular of different plastics. Preferably, the base has an angled cross-section with a leg which is opposite the narrow side of the window pane and a leg which is opposite the inside of the window pane.

The inner side opposite legs may have an open towards the window opening groove. Such a groove can serve the positive anchoring of the sealing profile on the guide rail, in particular can be introduced into the groove, a trim profile that surrounds an inside of the

Guide rail extends around and this covers the inside of the door.

The sealing profile may be anchored to the guide rail via at least one, preferably at least two, tongue and groove connections.

A direction in which the tongue and groove connection is plugged together, should be chosen so that a release of the tongue and groove connection is blocked by the window glass. In particular, a movement of the sealing profile to the center of the window opening may be blocked by a stop of a leg of the sealing profile on the narrow side of the window.

In order to hold the tongue and groove connection securely even when the disc is in the open position and at most slightly overlapping with the window opening, the sealing profile and the guide rail may have cooperating locking projections, wherein facing abutment surfaces of the locking projections transversely to the direction oriented, in which the tongue and groove connection can be plugged together.

In order to facilitate latching of the sealing profile on the guide rail, the latching projections may each have a ramp on a side remote from the stop surfaces in the plugging direction. By doing this

Sliding together of the tongue and groove joint, a temporary elastic deformation of the sealing profile can be enforced.

To ensure wind and water resistance and to form the above-mentioned elastic pad, the sealing profile can at least one inner

Include sealing lip, which bears against an inner side of the window pane. The inner sealing lip may be more flexible than the base of the sealing profile and

in particular be formed of the same material as the outer sealing lip.

Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

Fig. 2 is a section through one of the two doors with the

Window pane in open position;

Window pane in closed position;

Fig. 5 is a schematic section taken along the plane V-V of Fig. 4; and

Fig. 6 is a detailed section along the plane V-V

according to a further development;

Fig. 7 is a section through an upper rail of

Window frame according to the development; and

Fig. 8 is a section through an outer manhole strip. Fig. 1 shows an edge of a vehicle body with a front door 1 and a rear door 2. The doors 1, 2 fill a common opening of the body, of an A-pillar 3, a side roof frame 4, a C-pillar. 5 and a sill 6 is limited. A B pillar is hidden behind mutually facing edges of the doors 1, 2. The doors 1, 2 are each articulated in a hollow door body 7 below a belt line 8 and a window frame 9 above the waistline 8. Die

Window frames 9 each surround a large window opening with a window pane 10, which is movable between the shown in Figure 1, the window opening filling the closed position and a sunk in the door body 7 open position. It can, as shown, more window openings with immovable windows 11 may be present.

The adjustable windows 10 are each laterally bordered by extending in their adjustment guide rails 12, 13 of the window frame 9. The guide rails 12 of the two doors 1, 2 are opposite to each other in front of the B-pillar, on both sides of a gap 14, opposite.

Fig. 2 shows a vertical section through one of the doors 1, 2 with the

Window pane 10 in the open position. The window pane 10 is sunk in the door body 7 and guided along its front and rear edges in the vehicle longitudinal direction in guide profiles 15 with a U-shaped cross-section, one of which in Fig.

2 can be seen. The window pane 10 is cylindrically curved; Accordingly, the guide profiles 15 with the same radius of curvature as the window pane 10 are curved in a circular arc, so that the window pane 10, when it is in the open position and find their front and rear edges completely seated in the guide profiles 15 of the door body 7, is held tension-free between them ,

3 shows a schematic cross section through one of the guide profiles 15 and the edge of the window pane 10 received therein. The guide profile 15 is formed from a sheet steel and lined on its inside with a sliding layer 16 in order to allow direct contact of the steel with the window pane 10 prevent, which could produce during the movement of the window 10 grinding marks. An inner leg 18 of the guide profile 15 forms a contact surface on which an inner side 17 of the window 10 rests. Between an outer side 19 of the window pane 10 and an outer leg 20 of the guide profile 15, a narrow gap 21 extends. The two legs 18, 20 are connected via a base bar 22 which is opposite to an edge of the window pane 10. Referring again to FIG. 2, an inner and an outer channel strip 23, 24 close the door body 7 upwards. The outer channel strip 24 has a rib 25 projecting into the intermediate space between the channel strips 23, 24, against which the outer side 19 of the window pane 10 rests.

The guide rail 12 of the window frame 9 has, as shown in Fig. 5 in more detail, an L-shaped or Z-shaped cross-section with approximately at right angles

clashing legs 26, 27, one of which 26 extends the inner leg 18 and the other 27, the base bar 22 of the guide profile 15 up above the belt line 8 addition. The leg 26 is curved in a circular arc with the same radius as the inner leg 18, but the centers of curvature of the two legs 18, 26 do not coincide, so that both meet at the level of the rib 25 at an obtuse angle.

If, during an upward movement, the window pane 10 was guided only by the guide profile 15, starting from its open position shown in FIG. 2, it would, as illustrated in FIG. 2 by a dashed outline, have a

follow circular arc path whose center of curvature is the same as that of the legs 18, 20 of the guide profile 15. However, since the

Curvature centers of the guide profile 15 and the Führungsschienei 2 do not match, this way is blocked by the guide rail 12; the upper edge of the window pane 10 can only advance as far in the direction of the vehicle center as the guide rail 12 permits. Therefore, the leg 26 of the guide rail 12 forms a further contact surface to which the upper edge of the window 10 is always firmly pressed on the way to the closed position, so that they do not lose contact with the leg 26 under the influence of the airstream.

The vertical extent of the window pane 10 is at least 100 mm greater than that of the window frame 9, so that it is still guided in the closed position over a length of at least 100 mm in the guide rail 12 and is exposed by this to a torque sufficient to the

Window pane 10 in any position to keep pressed against the leg 26.

The window pane 10 may itself be deformable only to a small extent, in order to provide the necessary pressure between it and the leg 26 in each position Window pane 10 between the open position and shown in Fig. 4

To ensure closed position. Because of this, its thickness is over 4 mm;

4.85 mm thick discs are available on the market.

The guide rail 12 is like the guide profile 15 in itself substantially rigid. In spite of the rigidity of guide rail 12, guide profile 15, outer

Shaft strip 24 and window 10 is a vertical movement of

To allow window 10 and to avoid jamming, an elastically compressible sealing profile 32 is inserted between the inside 17 of the window 10 and the legs 26 of the guide rail 12.

According to a simple embodiment, the sealing profile 32 is an extrusion extruded profile extruded from a rubber-elastic plastic material having a base made up of two legs 34, 35 arranged at an angle to each other and attached to the legs 26, 27 of the guide rail 12, e.g. are attached by gluing. The elastic compressibility is ensured by inner sealing lips 36, 37, which bear on the inner side 17 of the window pane 10 starting from the leg 35.

The leg 34 of the sealing profile 32 is extended to the outside of the door by an outer sealing lip 38 which extends obliquely through a leg of the 27

Guide rail 12 and a narrow side 55 facing this

Window pane 10 limited, to the outside of the door open gap 42 extends. By having an end connected to the leg 34 of the outer

Sealing lip 38 abuts the leg 27 and an opposite, free end on the narrow side 55, the outer sealing lip 38 divides the gap 42 in an outer space, of the outer sealing lip 38 and the leg 27 of the

Guide rail 12 is limited and whose depth is smaller than the thickness of the window glass 10, and a shielded from the wind inside clearance, which is bounded by the sealing lip and the narrow side 55 of the window glass.

FIG. 6 shows a section analogous to FIG. 5 through the guide rail 12 according to a preferred development. A rigid carrier 28 of the guide rail 12, for example of one or more metal sheets, comprises a leg 29, only partially shown in the figure, exposed on the outside of the vehicle, a leg 30 extending transversely to the leg 29 into the vehicle interior, and an inner one Edge of the leg 30 subsequent, approximately parallel A sealing profile 32 covers the outer sides of the legs 30, 31. It comprises a rigid base 33 with cross-sectionally approximately L-shaped legs 34, 35, of which the leg 35 at one of the window opening facing edge into a U-profile section 56 passes, and a plurality of integrally formed on the base 33 elastic sealing lips 36, 37, 38. The sealing profile 32 is anchored to the carrier 28 by coming from the window opening in the vehicle longitudinal direction against the carrier 28 and thereby on the one hand a projection 39 of the leg 34 of the base 33 is inserted into a grooved in the leg 30 groove and on the other hand, a window opening facing edge of the leg 31 is engaged in a groove of the U-profile section 56.

From the leg 31 local tongues are notched and deflected to the outside of the door out to form locking projections 57. The free ends of the tongues face the leg 30 and form stop faces 58, which are essentially parallel to the leg 30. The sides of the window opening facing the window opening

Locking projections 57 are formed by ramps 59 which rise continuously obliquely from the leg 35 in the direction of the window pane 10.

Complementary to the latching projections 57 is on the sealing profile 32 a

continuously shaped in the longitudinal direction extending rib-shaped latching projection 60 shaped. The locking projection 60 has a substantially triangular

Cross-section, wherein one side of the triangle is connected to the base 33, a second side forms a stop surface 61, which faces the stop surfaces 48 approximately parallel, and the third forms a ramp 59 approximately parallel ramp 62.

If during assembly of the sealing profile 32 of the projection 39 in the groove of the

Leg 30 and the edge of the leg 31 in the U-profile section

is inserted, first meet the ramps 59, 62 to each other, and by sliding along each other, the sealing profile 32 is elastically deformed. The

Detent projection 60, like the sealing lips 36, 37, 38, may be formed of an elastically yielding material so that the deformation remains substantially concentrated on detent projection 60. Once the ramps 59, 62 have passed each other, the abutment surfaces 58-61 come to lie opposite each other and block a release of the sealing profile 32 from the carrier 28th To complete the assembly, a trim profile 40, for example made of a rigid plastic, is inserted into a groove 63 open towards the window opening between the leg 35 and the U-profile section 56 of the sealing profile 32 and against a side of the support, not shown, facing away from the window opening 28 locked.

6 shows the window pane 10 in a position flush with the leg 29, which occupies the window pane 10 when it has reached the closed position and its upper edge into a downwardly open groove of an upper rail 41 (see FIG. 2, 4) of the window frame 9 is engaged. In this position, the sealing lips 36, 37, which extend from the leg 35 of the sealing profile and rest against the inner side 17 of the window 10, only slightly deformed, since the pressure of the

Window 10 is distributed not only on it, but also on sealing lips of the upper rail 41.

In a partially open position, in which the window 10 has no contact with the upper rail 41, the sealing lips 36, 37 alone the pressure of

Window pane 10 exposed and therefore more deflected, so that the

Window slightly behind the leg 29 into the vehicle inside jumps back.

The outer sealing lip 38 protrudes from an outer edge of the leg 34 of the sealing profile 32 in a gap 42 open to the vehicle outside between a front or rear edge of the window pane 10 and the leg 29 and is elastically deflected by contact with the narrow side 55 of the window pane 10. By the outer sealing lip 38, the gap 42 - in particular when the

Window pane 10 as shown in Fig. 6 is flush with the leg 29 - fills except for small remaining free spaces 64, 65, it contributes to the minimization of

Fahrgeräuschs and the wind resistance at, besides they may be concealed by manufacturing tolerances or by the up and down movement of

Window 10 conditional fluctuating widths of the gap 42.

In the case of FIG. 6, the width of the gap 42 is dimensioned so that a free end of the outer sealing lip 38 in a same plane with the outer sides of the

Window 10 and the leg 29 is located. If the gap 42 is narrower than shown, the free end of the outer sealing lip 38 may be slightly above the plane projecting, when the gap 42 is wider than shown, the free end is set back slightly behind the plane in the gap 42 into it. In one case, as in the other case, the cross section of the outwardly open space 65 is only a small fraction of the cross section of the gap 42, so that relevant for the aerodynamics and driving noise turbulence are effectively suppressed.

When the window pane 10 is deflected out of the position flush with the leg 29 into the vehicle interior, it slides along the sealing lip 42, wherein the sealing rib 42 substantially retains its shape and pivots clockwise only about an axis adjacent to its leg 34 fixed to the leg to maintain a tight contact with the window glass 10 upright.

A sliding layer 16 is respectively provided on the sides of the sealing lips 36, 37, 38 facing the window pane 10 and on the leg 34.

Fig. 7 shows a cross section through the above-mentioned upper rail 41 of the window frame 9. On a - here assembled from two steel sheets - support section 43, a sealing profile 44 is attached. The sealing profile 44 comprises a rigid base 45 into which a latched onto an edge of the carrier profile 43

Staple 46 is embedded. At this base 45 a plurality of elastic sealing lips are formed around a downwardly open groove 47 around. Two of these sealing lips, designated 48, come on the inside 17 of the window 10 to the plant when it approaches the closed position, and thus increase the outward pressure on the window 10, so that the outside 19 when it reaches the closed position flush with the leg 29 comes to rest. Another

Sealing lip 49 is in the closed position at an upper edge of the window 10 at; the arrangement of the sealing lips 48, 49 thus substantially equal to that of the sealing lips 36-38 on the sealing profile 32. A fourth sealing lip 50 of the sealing profile 44 is in the closed position on the outer side 19 of the window 10 at.

Fig. 8 shows a cross section of the outer channel strip 24. Like the sealing profile 44, the outer channel strip 24 has a rigid base 51, in which a metallic

Clip 52 is inserted, which engages around an upper edge of the door body 7 and the slot strip 24 holds firmly locked to the door body 7. At one of the

Window-facing side of the base 51, two ribs are formed. One of them is resilient in contact with the outside 19 of the windowpane 10 deflected and acts as a sealing lip 53, which keeps away on the outside 19 running rainwater from the interior of the door body 7. The second rib 54 is not or at best to a small extent compliant. In order to move between the open and closed positions, the window 10 must therefore the

Deform contact surfaces of the legs 18 and / or 26. In the case of the leg 26, this is ensured by the resilience of the sealing lips 36, 37. A significantly lower compliance of the leg 18 and the rib 54 compared to the sealing lips 36, 37 ensures that a high and with

Increasing deflection strongly increasing force at the level of the upper edge of the window glass 10 is required to deflect the window pane 10 to the outside so far that the contact with the sealing lips 36, 37 is lost, and thus this contact always exists under realistic driving conditions.
