Description

technical field

The present invention relates to a motor vehicle body with a motor vehicle door (KFZ stands for motor vehicle) and a sill. Generic are already in the prior art from the DE102012001938A1 and EP2014539B1 known.

Technical task

The technical task is to improve the entry and exit area for the front door and rear door so that it is easier for users to enter and exit. It's the lower door entry area.
Better means the following criteria here: more space for the user of the vehicle in the area of the sill and thus more comfort, more safety when entering and exiting, especially when exiting, more protection against dirt and moisture.

This is achieved by reducing the size of the sill in a partial area, the indentation in the sill (16) on the outer part of the sill (5.1), and expanding the door construction, the indentation in the vehicle door (15), which again covers the indentation in the rocker (16). .

Technical solution

The technical solution is to fit the sill (5), which consists of an outer part sill (5.1) and an inner part sill (5.2), as well as a middle part sill (5.3), in the area of the outer part sill (5.1) with an indentation sill ( 16) and attach the bulge car door (15) to the car door (2).

This sill indentation (16) should be removed from the outer edge of the sill (5.4) to in front of the middle part of the sill (5.3) as shown in 4 can be seen when viewed from above, i.e. open at the bottom. The width of the indentation (7) can be adapted to the requirement as required and the type of vehicle. The indentation sill (16) in 4 , may be wider or narrower. The position of the sill indentation (16) on the sill (5) itself can also be shifted, it does not have to be in the middle, since there are different requirements due to the type of vehicle and front door or rear door.

The dismantling of the sill (5) and the indentation in the sill (16) does not have to go all the way to the center part of the sill (5.3). On the middle section of the sill (5.3), in many vehicles, two sill halves, outer and inner, are assembled at this joint and the rubber seals are placed on top of the sill (5), it should stay that way.

How from the 4 can be seen, there is an indentation (16) when looking at the rocker (5) from above, which runs vertically or almost vertically downwards. This indentation sill (16) is the legroom when getting in and out, which is achieved with it.

But the essential thing is to close this indentation in the sill (15), otherwise there would be a gap in the area of the sill (5) at the bottom. Therefore, the car door (2) is enlarged downwards, as in comparison 1 and 2 you can see. In the 2 and the lower edge of the vehicle door (4.2) pulled downwards, the dotted line shows the seat of the new construction of the bulge in the vehicle door (15).

While with the old construction 5 the lower edge of the inner part of the vehicle door (13) still closes further up because of the sill (5), is in the vehicle door (10) in the new design 6 , the bulge in the vehicle door (15) is present underneath, which now closes the sill indentation (16) when the vehicle door is closed. This makes the door slightly larger at the bottom, since the car door bulge (15) was attached.

At 1 you can still see that the sill (5) is below the lower edge of the vehicle door (4.1). 2 you can see that the car door (2) with the lower edge of the car door (4.2) now extends downwards. The new construction with the car door bulge (15) toward the vehicle interior is now in the dotted area, with the width of the car door bulge (15) not covering the entire width of the car door up to the vertical columns car -Door (22) must extend left and right. But the outer sheet metal of the vehicle door (2) should be installed over the entire width of the vehicle door (2) up to the vertical columns of the vehicle door (22) on the left and right. This makes the construction almost invisible from the outside, as it is covered by the door. It remains only under the lower edge of the vehicle door (4.2), see 7 , a small view of the sill and the curve on the outside (20), which consists of the lower part of the car door bulge (15).

However, it is also possible for the lower edge of the vehicle door (4.2) to be moved downwards only at the position where the bulge in the vehicle door (16) is present and
to leave the lower edge of the vehicle door (4.1) in the position further up, where there is no bulge in the vehicle door (15). But then the gaps on the car door in the area of the sill (5) would be arranged differently, which would lead to a design problem, so this is not recommended.

It is to be understood that the bulge in the vehicle door (15) now has the function of the sill (5) in place in order to close the gap created by the bulge in the sill (16).

construction details

The sheet metal parts of the car door bulge (15) and the sill indentation (16) on the sill (5) must not touch when the door is closed, with the gap dimensions corresponding to the other gap dimensions on the car door. Today, the essential seal is attached to the center section of the sill and runs up there to seal the entire door all around, and it will stay that way.

Since there is now another gap in the underbody, another seal or cover should be fitted. Since there is a lot of splashing water in the underbody area. A distinction is made between sealing, which is done with rubber seals and closing the gap between the two parts bulge and indentation, and cover, in which only the gap is covered from below, but is still open so that hardly any splashing water gets into the gap.

A cover is included 13 clearly visible. At the corner position of the bulge (15.1) either a rubber or a metal strip is attached horizontally to the inner course of the bulge car door (15.3). The gap is still open, but is essentially covered. At 14 it is a seal in the form of a rubber seal, since the gap between the indentation and the indentation (8) is closed here with the car door bulge seal (15.5). The car door bulge seal (15.5) could also be attached to the indentation corner position (16.1). It is constructed in such a way that no parts protrude downwards, so the underbody is smooth. Instead of a horizontal course of the seal for the bulge in the motor vehicle door (15.5), the seal can also run slightly obliquely from the front area of the motor vehicle (23) from top to bottom, so that any water can drain off better.

In cars in general, water can go down between the gaps in the area of the sill, e.g. between the fender and the edge of the door, and it can also get into the structure in small quantities via the upper part of the outer sill. Therefore, depending on the type of construction, a decision must be made as to whether water can drain off and a horizontal seal is not so good. The water can then run off with the cover or a slanted course of the seal.

A similar procedure can also be used for the lateral course of the bulge in the vehicle door (15.2). However, it should be noted here that when the car door is closed, the rubber seal then hits the lateral indentation (16.2) and hits something transversely, which could result in some squeaking noises. Since a soft rubber seal can be better. The rain deflectors (9) can be seen as a cover on the lateral course.

1. A Der rundliche Verlauf Ecke Ausbuchtung (15.4).
2. B Während der 1. seitlichen Verlauf, aus Frontbereich KFZ (23) gesehen, noch mit einem steilen Winkel nach innen geführt werden kann. Kann der 2. seitlichen Verlauf, aus Frontbereich KFZ (23) gesehen, mit einem flachen Winkel nach innen geführt werden kann. Bei 15 sind die unterschiedlichen Winkel dargestellt, der Winkel A1 (24) führt zu einem steilen Verlauf, der Winkel A2 (25) führt zu einem flacheren Verlauf. Winkel A1 (24) könnte ca. 80 Grad haben, Winkel A2 (25) könnte ca, 60-70 Grad haben. Die Winkel der seitlichen Verläufe Ausbuchtung müssen mit den Winkeln der seitlichen Verläufe Einbuchtung übereinstimmen, damit die Spalten gleich verlaufen. Es ist aber zu beachten, die seitlichen Verläufe können insgesamt mit einer kleinen Rundung verlaufen. Hier sind sie trapezförmig dargestellt, mit einer Rundung in den Ecken und mit unterschiedlichen Winkel.

Lösung A und B sind optimal zu kombinieren.The motor vehicle door (2) is attached to a hinge and when the motor vehicle door (2) is opened and closed, the bulge in the motor vehicle door (15) is therefore fitted at a slight angle into the sill indentation (16). Therefore, at the bottleneck when the door moves (15.6), there could be a small area that jams on the lateral course of the bulge in the motor vehicle door (15.2). Because of the gap less the sheet metal, but with the rubber seals. There are two solutions:

1. A The rounded curve at the corner of the bulge (15.4).
2. B While the 1st lateral course, seen from the front area of the vehicle (23), can still be guided inwards at a steep angle. The 2nd lateral course, seen from the front area of the vehicle (23), can be guided inwards at a shallow angle. At 15 the different angles are shown, angle A1 (24) leads to a steep gradient, angle A2 (25) leads to a flatter gradient. Angle A1 (24) could be around 80 degrees, Angle A2 (25) could be around 60-70 degrees. The angles of the side bulges must match the angles of the side indents for the columns to be equal. It should be noted, however, that the lateral gradients can run with a small curve. Here they are shown in a trapezoidal shape, with a curve in the corners and with different angles.

Solution A and B can be optimally combined.

The bulge in the motor vehicle door (15) extends only over a portion of the door, the size of the bulge in the sill (16) on the sill (5). The indentation of the sill (16) can be made up to the middle part of the sill (5.3), or there can be a few centimeters of space in between so that the construction can be reinforced with a metal strip if necessary. But the closer the sill indentation (16) is to the middle part of the sill (5.3), the greater the free space that is available when entering and exiting.

As in 2 can be seen, the lower edge of the car door is all the way down or almost all the way down pulled down and the bulge in the vehicle door (15) installed on the inside of the vehicle. The rounding on the outside (20) can still be seen a little downwards.

The visible part of the car door bulge (15) is painted. As is the case today, the part underneath on the vehicle floor is provided with a robust special compound.

The vehicle door (15) should be completely closed on all sides.

On the outside, it is simply a part of the vehicle door (2), with the sheet metal being extended downwards and the bulge in the vehicle door (15) towards the inside of the vehicle and being installed on all sides. The bulge of the vehicle door (15) is essentially attached to the inside of the outer part of the vehicle door (12) and to the lower edge of the inner part of the vehicle door (13) by being welded there or is already part of the body shape.

The 10 shows a way to make the bulge car door (15) interchangeable. The lower edge of the car door only goes up to the fastening position 1 of the inner panel of the car door (17), where the replaceable car door bulge (15) is attached. A transverse metal edge can be attached at this point for fixation and support. It must be sure that the part does not fall off. Of course, the metal edge or fixing strip or fixing points could also be higher on the car door. In addition, it must be welded or screwed to the inside of the outer part of the vehicle door (12). A second fastening is provided at a further fastening position, the lower edge of the inner part of the motor vehicle door (18). In order to attach it stably, it can be fixed here with an additional metal strip.

On vehicles with 4 doors, the construction can be done on all 4 doors or only on the 2 front doors or even only on the rear doors.

The 9 shows a possible construction in which the car door bulge (15) is open, this is shown for comparison, this should then cause problems due to the existing cavity due to additional noise/dirt exposure, this is not recommended.

Getting in and out of the vehicle

Getting into the car is still quite easy, as one leg is placed inside the car, then one sits on the seat and pulls one's leg up. But here, too, older people have a need for safety and it is also due to their flexibility, first sitting down on the seat at an angle of 90 degrees and then pulling leg by leg into the inside of the car and turning 90 degrees on the seat degrees to rotate. Much more often it can be seen that older people first put both legs out of the car on the ground and only then get out of the seat. You almost inevitably come into contact with the edge of the sill and can get dirty, but also if you get out of the seat as soon as one leg is out. So A has a pollution problem and B, more importantly, a sill as it is today makes it difficult to get out because you can't pull your legs that close to the seat. When converting the sill with conversion of the door as suggested here, the user can pull the legs about 8-12 cm closer to the seat.

It doesn't just have to be about the elderly. There are also sports cars
whose seats are very low. In order to be able to get out here easily, one would have to be able to pull one's legs closer to the seats. But even the popular SUVs, which are built particularly high, often have the problem that the sill is actually in the way. When a married couple is traveling, one is tall and the other is short, the sill is always the same size, and despite the seat's height adjustability, the sill is often annoying. Therefore, the size of the people is also an important factor. With a conversion, as proposed here, the situation when entering and exiting the vehicle improves significantly in some types of vehicle. Even when it is wet there is the problem that you touch the sill with your legs when you get out and get your legs wet. This is hardly possible with the new design. Since the sill indentation (16), with which you can come into contact when getting in and out, is covered by the vehicle door bulge (15) while driving, the sill indentation (16) remains largely dry and dust-free. It should be explained that the essential sealing is done on the rubber seals of the doors. Dust and moisture can get into the outer joints, but this is significantly reduced at the possible contact position in the rocker panel indentation (16).

So there are several aspects that can be solved. More protection against dirt because there is less contact with the sill. More comfort due to more space when getting in and out, more safety for older people because the legs can be brought closer to the seat.

With the positioning and width of the indentation sill (16), the construction must be built in the area of the possible seating position, since the user turns 90 degrees on the seat and brings his legs out of the vehicle there. This is different for the types of vehicles, is it a two-seater or a four-seater, does it have 2 doors or 4, is it on the front doors or on the rear doors, is the B-pillar further back or forward due to the vehicle length, based on the seating position, is it an SUV, a sports car or a car specifically for older people?

But it's easy with the front door if the sill indentation (16) begins right next to the B-pillar. The wider the indentation sill (16) is designed, the easier it is. With the rear door, the entry area is smaller because the wheel housing is present, so you could do without it, especially since it is used less in the rear area.

With this solution, a motor vehicle could be equipped, which is especially suitable for older people. However, it can also be used in other types of vehicles.

• 1 shows the floor plan of a motor vehicle (1) from the side. Here a car with 2 doors is shown and with the old construction. The car door (2), the sill (5), the B-pillar (3) and the lower edge of the car door (4.1), which is further up.
• 2 shows the floor plan of a motor vehicle (1) from the side. Here a car with 2 doors is shown and with the new design. The car door (2), the sill (5), the B-pillar (3) and now the lower edge of the car door (4.2), which goes further down and the vertical door columns (22) on the left and right. The bulge in the vehicle door (15) shown in dashed lines is inward behind the vehicle door (2) and runs down between the vertical dashed lines.

Where there is no bulge in the car door (15), you can simply remove the sheet metal of the sill (5) a little to have space for the lower edge of the car door (4.2) that has been moved downwards, while the sill (5) is thicker of the sheet metal.

The lower edge of the car door (4.2) can be placed so far down that you can no longer see the sill from the outside or a little higher leave so that the rounding on the outside (20) can still be seen downwards and from the outside, see also 7 . The same can be done for vehicles with 4 doors. For vehicles with 4 doors, the bulge in the rocker panel (5) could only be on the front vehicle doors or on all 4 vehicle doors.

The 1st rain deflector (9) is attached to the sill in front of the lateral course of the sill indentation (16.2), as seen from the front area of the vehicle (23), in order to deflect rainwater here and guide it through the gap.

The 2nd rain deflector (9) is attached to the bulge vehicle door (15) in front of the lateral course of the bulge vehicle door (15.2), as seen from the front area of the vehicle (23), in order to deflect rainwater here and guide it through the gap.

The rain deflectors start below the lower edge of the vehicle door (4.2) along the outside curve (20) on the side columns and go to the corner position of the bulge (15.1).

The rain deflector (9) should only have a small edge of approx. 1 cm elevation to guide the water through the gap here due to the driving speed. The gap here means the space between the metal sheets between the sill indentation (16) and the car door indentation (15).

It should be noted that some cars today already have an outer door panel that is drawn downwards, but only to cover the sill a bit. The attachment of the bulge to the car door is essential.

3 shows a section of the sill (5) seen from above in the old form.

The outer part of the sill (5.1), the inner part of the sill (5.2) and the middle part of the sill (5.3), on which the rubber seals run and the sheet metal is normally welded at this seam. It is called the outer part because it is on the outside of the vehicle, and the inner part because it is attached to the inside of the vehicle.

4 shows a section of the sill (5) and the sill indentation (16) seen from above in the new shape.

The outer part sill (5.1), the inner part sill (5.2) and the middle part sill (5.3). Here you can see the sill indentation (16), the width of which (7) can vary, depending on the requirements of the vehicle type and whether it is on the front door or rear door. The lateral course of the indentation (16.2) also runs trapezoidally inwards in the direction of the middle section of the sill (5.3), so that the vehicle door can be closed without jamming; it can be straight or slightly curved. The lateral course of the indentation (16.2) should change into a rounded course of the corner of the indentation (16.4).

Starting from the outer edge of the sill (5.4), the indentation in the sill (16) should be 5 cm to 12 cm or, if more cm is possible, in the direction of the middle part of the sill (5.3) in order to get as much space as possible. Due to the resulting indentation, another metal reinforcement can be installed in front of the middle part of the rocker panel (5.3) towards the indentation of the rocker panel (16), also with a U-shaped metal reinforcement, with the angle of the lateral indentation, which also defines the lateral course of the indentation (16.2 ) strengthened.

The angles of the lateral course of the indentation (16.2) can also be different. This will at 15 shown / explained.

The outer edge of the sill (5.4) runs where there is no indentation in the sill (16). This is essentially covered by the vehicle door (2) and its lower edge 2 vehicle door (4.2). In this case, a lower edge of the vehicle door (4.2) is also placed as a design over the bulge in the vehicle door (15) on the vehicle door (2).

5 shows the lower part of a car door and a cross section of the car door (10) from the side and in the old form. The inner part of the car door (11), in which the window box is located and the outer part of the car door (12), and the inside of the car door (14). At the lower edge of the inner part of the motor vehicle door (13), the inner part of the motor vehicle door closes off at the bottom and partially covers the sill (5) from above when the door is closed.

6 shows the lower part of a car door and a cross section of the car door (10) from the side and in the new form. The inner part of the car door (11), in which the window box is located and the outer part of the car door (12), and the inside of the car door (14).
The car door indentation (15) on the underside of the car door, which is shaped to fit into the sill indentation (16), is new 4 to fit. It should be noted that 6 is drawn in cross-section from the side, the 4 from above. When the vehicle door is closed, the sill indentation (16) can no longer be seen from the outside, since the vehicle door bulge (15) is used as a replacement for the sill (5) in the width of the sill indentation (16). . The outer part of the door (12) is extended and, with the rounding on the outside (20) downwards, represents the outer wall of the bulge in the sill (15). The bulge in the sill (15) should be closed on all sides and can be part of the lower edge of the inner part of the vehicle door (13) be or be attached there with your own reinforcement or your own sheet metal.

7 shows a section of the lower car door from the outside to the lower edge of the door.

The outer part of the vehicle door (12) and, with the dotted shape, the central bulge in the vehicle door (15) which is present behind it and which faces the interior of the vehicle. Below the lower edge of the vehicle door (4.2), the sill (5) can still be seen, it also extends beyond the width of the door and is marked with the dotted lines to the left and right of the bulge in the vehicle door (15) behind the outer part of the vehicle door ( 12) present.

8th shows the lower part of a motor vehicle door and a cross section of the motor vehicle door (10) from the side, with the bulge of the motor vehicle door (15) in the lower part and next to it the sill (5) which is attached to the vehicle floor (21). Here you can see how the parts fit together when the car door is closed.
The inner part of the car door (11) is in the upper part. Beneath this is the car door bulge (15), in which the outer panel of the door (12) runs to the corner bulge (15.1), with the lower edge of the car door (4.2) being further up and there in the rounding on the outside ( 20) passes. It should be noted that the car door bulge (15) is firmly connected to the car door (2), which is why the bottom edge2 of the car door (4.2) is horizontal across the entire door width with one edge, without the bottom edge2 Car door (4.2) in the area of the bulge car door (15) results in an opening.

In the case of the vehicle door (2), the opening of the vehicle door (15) extends to the opening of the sill (16) when the vehicle door is closed, with a door gap remaining open so that the metal sheets do not touch.

The figure shows how the car door recess (15) attached to the door, when the door is closed, joins the sill recess (16) connected to the sill (5). Whereby this is only on the width of the indentation (7), as in 4 is shown, takes place.

9 shows the lower part of a motor vehicle door and a cross section of the motor vehicle door (10) from the side.

Here the car door (15) is shown open. Here only the outer part of the car door (12) runs to the corner position of the bulge (15.1). The bulge in the vehicle door (15) could therefore only be provided with the extended outer part of the vehicle door (12), but this cannot be implemented so well for various reasons that are explained in the description and is not recommended. It is essential that a cavity is created. The figure is shown for comparison only.

10 shows the lower part of a motor vehicle door and a cross section of the motor vehicle door (10) from the side.

Here it is shown that the recessed vehicle door (15) is also fastened inside as an extra part on the outer part of the vehicle door (12). At fastening position 1 inner panel car door (17) there is a fastening option to which the recessed car door (15) can be attached interchangeably as an extra part, as well as at fastening position 2 lower edge inner part car door (18).

Fixing positions can vary and the part can be welded or bolted on. The advantage here is that the part can be replaced, but it is probably more complex to produce. It is more stable if it is connected to the outer panel of the door (12) in one piece. Since the lower edge of the inner part of the car door (13) is normally made of sheet steel on car doors, this is a good fastening option, but it can be even stronger with a metal strip that is attached to the lower edge of the inner part of the car door (13). be fixed.

11 shows the cross section of the sill (5) from the side in the position of the indentation sill (16) and the middle part sill (5.3) and the inner part sill (5.2). It can be seen that the sill indentation (16) replaces the outer part of the sill (5.3) at this point. The lateral curves are not shown.
A small chamfer should be installed at the corner position of the indentation (16.1) along the width of the indentation (7), which has several functions. If such an edge is present, possible water ingress is diverted again over this edge and the user of the vehicle does not come into contact with it. Furthermore, the gap is covered from below to protect against water and, if necessary, also provided with a rubber seal. There is also an explanation 13 and 14 . The sill is attached to the vehicle floor (21).

12 shows a section of the bulge in the motor vehicle door (15) viewed at a slight angle from above and from the outer part of the motor vehicle door (12), the outer part of the motor vehicle door (12) only being shown as a position here.

The dimensions of the lateral course of the car door bulge (15.2) must be matched to the lateral course of the sill indentation (16.2) so that the car door (2) closes smoothly and a gap between the indentation and bulge (8) remains open , so that the sheets do not touch, which does not apply to gaskets. The plump ver The corner bulge (15.4) has the round shape of the corner indentation (16.4) with a gap that is also open. The gap will be approx. 0.2 to 1.0 cm, as is usual with the bodywork, with the gaps on the doors. The round shape goes from the upper edge to the lower edge of the bulge in the vehicle door (15), analogous to the bulge in the sill (16).

The lateral course of the bulge in the motor vehicle door (15.2) transitions into a rounded course in the corner of the bulge (15.4) if the rounded course in the corner of the bulge (16.4) is present in the indentation on the sill.

The rounded gradients in the corners aren't necessary, but they make the doors easier to close. Alternatively, different angles, see 15 .

13 shows a section of the bulge in the vehicle door (15) on the left-hand side and a section of the bulge in the sill (16) on the right-hand side. It's about showing how the corner bulge (15.1) of the
Gap between indentation and bulge (8) is only covered, not closed. The gap between the indentation and the bulge (8) is also present on the lateral courses and is not shown here.

14 analogously shows a section of the bulge in the vehicle door (15) on the left-hand side and a section of the bulge in the sill (16) on the right-hand side 13 .
The aim is to show how the gap between the indentation and the bulge (8) is closed with a bulge-car door seal (15.5) at the corner position of the bulge (15.1). A horizontal course of the seal is shown here, which extends across the width of the indentation (7).

But it can how 13 only be covered and additional seals are laid further up horizontally or at an angle on the bulge in the vehicle door (15). Seals on the lateral courses are not shown here, but they can be sealed in the same way.

15 shows a section of the bulge in the vehicle door (15) viewed at a slight angle from above and from the outer part of the vehicle door (12), the outer part of the vehicle door (12) being shown here only as a position, analogously 12 . Shown here are the lateral curves of the bulge of the motor vehicle door (15.2) with different angles (24, 25) and with the round curve of the corner of the bulge (15.4).
