Description

The invention relates to an arrangement of two wing elements, in particular side doors, on a body of a motor vehicle according to the preamble of patent claim 1.

Arrangements of side doors on passenger car bodies are well known from the series production of motor vehicles. At this time, a front side door is attached to the A pillar of the passenger car body. A rear side door is hinged to the C-pillar of the passenger car body. The side doors can be moved in opposite directions relative to the passenger car body between at least one respective open position and a closed position. In the closed position, the front side door closes a front door opening assigned to it. In its closed position, the rear side door closes an associated rear door opening of the passenger car body.

In relation to the longitudinal direction of the vehicle, the front door opening is limited at the front by the A pillar and at the rear by the B pillar of the passenger vehicle body. The rear door opening is limited to the front by the B-pillar and to the rear by the C-pillar. In their closed positions, the side doors are sealed against the passenger car body via the B-pillar by means of respective sealing elements.

From the DE 600 09 986 T2 An arrangement of a front side door and a rear side door in the longitudinal direction of the vehicle on a body of a passenger car is known. In this arrangement, the side doors are held on the body such that they can pivot relative to the body between a respective closed position and at least one respective open position. In the closed positions of the wing elements, the wing elements can be used to close an opening in the body that is delimited by a front body pillar and a second body pillar that is spaced apart from the first body pillar in the longitudinal direction of the vehicle and that is uninterrupted between the body pillars.

A sealing element is fastened to the front side door and rests against the rear side door in the closed positions, so that the side doors are sealed from one another in the closed positions. This known arrangement has the disadvantage that the side doors cannot be opened and closed independently of one another. If the side doors are in their closed positions, the rear side door must first be opened in order to then open the front side door. This is the only way to avoid undesired damage and an undesirably high load on the sealing element.

The DE 10 2008 005 490 A1 discloses a motor vehicle with a front and a rear side door, seen in the direction of travel, for closing a lateral, continuous door cutout opening in a body of the motor vehicle. The DE 10 2005 034 737 A1 a motor vehicle can be seen as known, with side doors designed as butterfly doors. In addition, from the DE 60 2004 008 566 T2 an automobile body structure is known.

It is therefore the object of the present invention to further develop an arrangement of two wing elements on a body of a motor vehicle of the type mentioned at the outset in such a way that reliable sealing is ensured in the closed positions of the wing elements and the wing elements can be moved independently of one another between their closed positions and their open positions.

This object is achieved by an arrangement of two wing elements on a body of a motor vehicle with the features of patent claim 1. Advantageous configurations with expedient and non-trivial developments of the invention are specified in the remaining claims.

With such an arrangement of a first wing element and a second wing element on a body, in particular a body, of a motor vehicle, the wing elements on the body are held pivotably between a respective closed position and at least one respective open position relative to the body.

The body has an opening delimited on the one hand by a first body part and on the other hand by a second body part of the body spaced apart from the first body part and without an interruption between the body parts. The opening can be closed by means of the wing elements in their closed positions and can be opened or released at least in certain areas in their open positions.

At least one first sealing element is held at least on the first wing element. The sealing element serves to seal off the wing elements from one another in their closed positions.

According to the invention, at least one second sealing element is provided, which on the second wing element merges with the latter between the closed position and the open position is kept safe. The second sealing element is movable relative to the first sealing element and relative to the second wing element between at least one release position and at least one sealing position. In the sealing position of the second sealing element, the second sealing element interacts with the first sealing element, so that the wing elements are mutually sealed in the closed positions.

Due to the mobility of the second sealing element relative to the first sealing element and thus relative to the first wing element, it is possible to move the wing elements independently of one another between the respective open position and the respective closed position. This means that, for example, the first wing element does not first have to be moved into the open position in order to then also be able to move the second wing element into the open position or vice versa.

If the wing elements of the arrangement according to the invention are, for example, in their closed positions and only one of the wing elements is to be moved from its closed position to its open position, the sealing element can first be moved from its sealing position, which it assumes in the closed positions, to its release position. Then an independent movement of the wing elements between the closed positions and the open positions is possible. This leads to a very high level of operating comfort for the arrangement.

Furthermore, the arrangement according to the invention enables a reliable and secure mutual sealing of the wing elements in their closed positions, so that, for example, dirt and moisture are prevented from penetrating into an interior of the motor vehicle via the opening. Furthermore, the arrangement according to the invention has the advantage that the reliable sealing as well as the independent mobility of the wing elements is possible in the case of the uninterrupted, i.e. continuous openings of the structure between the structure parts. A structural part dividing the opening into two partial openings is not provided and is not necessary. This benefits the visual impression of the motor vehicle, particularly when the wing elements are in the open positions. In addition, the interior is then accessible via the uninterrupted, continuous opening over the entire cross section of the opening and is therefore particularly large and easy to access.

This is particularly advantageous if the first wing element is a front side door and the second wing element is a rear side door that follows behind it in the longitudinal direction of the vehicle. The opening is an uninterrupted, continuous door opening which is delimited in the longitudinal direction of the vehicle to the front by the first body part and to the rear by the second body part and extends between the body parts without interruption. The first body part is a front vehicle pillar of the body. The second body part is a vehicle rear pillar of the body.

In the open positions, the side doors, which can be opened and closed in opposite directions to one another, allow particularly large-area and comfortable access to the passenger compartment of the motor vehicle designed, for example, as a passenger car. The structure is preferably designed as a body, in particular a self-supporting body, of the motor vehicle.

According to the invention it is provided that the second sealing element has a higher rigidity than the first sealing element. This makes it possible for the second sealing element in its sealing position to deform the first sealing element at least in regions compared to an initial state of the first sealing element in which the second sealing element does not interact with the first sealing element. The first sealing element, which is softer than the second sealing element, can rest against the second sealing element and at least in some areas around it when interacting with it, so that a very good sealing effect is achieved.

In addition, the second sealing element can be moved in a first sealing area in a first direction of movement and in a second sealing area in a second direction of movement that differs from the first direction of movement between the release position and the sealing position, in that in the first sealing area there is a shift between the release position and the sealing position and Pivoting or rotating is provided in the second sealing area. In this way, varying geometry and thus sealing conditions along the sealing elements or along the second sealing element can be taken into account, and reliable sealing can also be ensured under these varying conditions.

In order to achieve very good tightness, it is preferably provided that the second sealing element rests against the first sealing element in its sealing position.

The first sealing element is preferably an elastic element, in particular made of rubber, with the second sealing element being stiffer or more rigid and, for example, at least essentially inherently rigid. The second seal element can be designed as a sealing strip or the like. The first sealing element can thus bear against the second sealing element advantageously and over a large area.

Of course, a corresponding reversal of action is possible, in which case the second sealing element is softer or more elastic than the first sealing element. The second sealing element can then be deformed by the first sealing element when interacting with the first sealing element, can rest on or around the first sealing element and thus ensure an advantageous sealing effect.

The second sealing element is, for example, translationally displaceable between its release position and its sealing position, pivotable about at least one pivot axis and/or rotatable about a rotary axis.

In a further particularly advantageous embodiment of the invention, at least one third structural part, in particular a third body part, protrudes into the opening in a transition area in which the wing elements adjoin one another in the closed positions, i.e. without interrupting the opening between the structural parts in. The third body part has respective sealing surfaces for sealing the body to the wing members. In this case, the wing elements in their closed positions rest at least indirectly, in particular via respective sealing elements, on the sealing surfaces of the third structural part. The sealing surfaces of the third structural part run at least essentially obliquely or perpendicularly to further sealing surfaces adjoining the sealing surfaces, which are formed by further structural parts of the structure delimiting the opening.

In this case, for example, a sealing triangle is formed in the transition area by the third structural part and its sealing surfaces, by means of which a secure sealing of the superstructure to the wing elements in the transition region is made possible. This, together with the advantageous mutual sealing of the wing elements, prevents dirt and moisture from penetrating into the interior, in particular into the passenger compartment.

In a further advantageous embodiment of the invention, at least one of the wing elements has an actuating element, in particular a handle element, for moving the associated wing element between its open position and closed position. If the actuating element is actuated in order to move the associated wing element from the closed position to the open position, this causes the second sealing element to be moved from its sealing position to its release position.

Both wing elements preferably have a respective actuating element. If the actuating element of the first wing element is actuated, this causes the movement of the second sealing element from the sealing position into the release position. Also, actuation of the actuating element of the second wing element causes the movement of the second sealing element from the sealing position to the release position. As a result, the wing elements can be moved completely independently of one another between the respective open position and the respective closed position. This benefits the operating comfort of the arrangement according to the invention.

Such an arrangement of the first wing element and the second wing element on the body is also disclosed, in which in the transition region in which the wing elements adjoin one another in the closed positions, at least the third body part is partially interrupted, i.e. without interrupting the opening between the body parts. projects into the opening and has the respective sealing surfaces for sealing the structure to the wing elements.

The sealing surfaces of the third structural part preferably run at least essentially obliquely or perpendicularly to the further sealing surfaces adjoining the sealing surfaces of the further structural parts of the structure delimiting the opening. The sealing triangle in the transition area is preferably formed by the third structural part and its sealing surfaces, by means of which a secure sealing of the superstructure to the wing elements in the transition region is made possible.

This prevents dirt and moisture from penetrating into an interior, in particular into the passenger compartment, of the motor vehicle.

The drawing shows in:

• 1 a fragmentary schematic sectional view of an arrangement of two side doors on a passenger car body, which are mutually sealed in their closed positions by means of two sealing elements, one of the sealing elements being held on one of the side doors relative to the side doors and relative to the passenger car body so that it can move; and
• 2 a detail of a schematic side view of the passenger car body, the lower side sills of which protrude into a door opening assigned to the side doors in a transition area in which the side doors adjoin one another in their closed positions, as a result of which a sealing triangle is formed, by means of which the passenger car body is sealed against the side doors in their closed position .

The 1 shows an arrangement 10 of a front side door 12 and a rear side door 14 adjoining it in the longitudinal direction of the vehicle at a location in FIG 1 not shown passenger car body 16 ( 2 ). The front side door 12 is attached to an A-pillar of the passenger car body 16 via at least one hinge. The rear side door 14 is attached to a C-pillar of the passenger car body 16 via at least one hinge. About the respective hinges are the side doors 12, 14 between a respective in which 1 shown closed position and at least one respective open position relative to the passenger car body 16 pivotable.

The side doors 12, 14 are associated with a common door opening 18 of the passenger car body 16. The door opening 18 extends without interruption in the longitudinal direction of the vehicle between the A pillar and the C pillar. This means that the door opening 18 is delimited in the vehicle longitudinal direction to the front by the A pillar and in the vehicle longitudinal direction to the rear by the C pillar. There is no further body pillar between the A pillar and the C pillar, such as a B pillar, for example, which divides the uninterrupted and continuous door opening 18 into two partial openings.

In the vertical direction of the vehicle, the door opening 18 is also uninterrupted or continuous and is bounded at the top by a roof frame of the passenger car body 16 and at the bottom by a side sill 20 of the passenger car body 16 . The door opening 18 extends not only between the A pillar and the C pillar, but also between the roof frame and the side sill 20 without any interruption. The door opening 18 thus has a particularly large, continuous cross section, via which the passenger compartment of the passenger car is easily accessible when the side doors 12, 14 are in their open positions.

This means that the door opening 18 is released at least in certain areas in the open positions. The door opening 18 can be closed by means of the side doors 12, 14 in the closed positions. The front side door 12 closes the door opening 18 in a front part area. The rear side door 14 closes the door opening 18 in the closed position in a rear partial area.

To seal the side doors 12, 14 from one another, in order to prevent dirt and moisture from entering the passenger compartment, a first sealing element 22 is pivotably mounted on the front side door 12 with the front side door 12. The first sealing element 22 is a rubber seal in the form of a hose seal, which extends at least in regions in the circumferential direction of the front side door 12 .

To seal the side doors 12, 14 from one another, a second sealing element is provided in the form of a sealing strip 24, which is held on the rear side door 14 and can be pivoted with it. Like in the 1 is indicated by a broken line, the at least essentially inherently rigid sealing strip 24 is between a sealing position shown by a solid line and a release position shown by the broken line relative to the rear side door 14, relative to the passenger vehicle body 16 and relative to the front side door 12 and thus relative to the first sealing member 22 movable.

In the sealing position, the sealing strip 24 bears against the first sealing element 22 and is in contact with the first sealing element 22 . In the release position, the sealing strip 24 is out of contact with the first sealing element 22. This means that the sealing strip 24 does not touch the first sealing element 22 in the release position.

It is thus possible for the side doors 12, 14 to be moved independently of one another between the respective open positions and the respective closed positions without subjecting the first sealing element 22 and/or the sealing strip 24 to undesirably high forces and correspondingly undesirably damaging them. At the same time, in the closed positions of the side doors 12, 14 and in the sealing position of the sealing strip 24, the side doors 12, 14 are reliably sealed.

The sealing strip 24 is held on the side door 14 so that it can move between the release position and the sealing position by means of a holder 26 fastened to the side door 14 . In the present case, the sealing strip 24 can be displaced in the longitudinal direction of the vehicle between the sealing position and the release position.

The sealing strip 24 has a higher strength or rigidity than the elastic first sealing element 22 . As a result, the first sealing element 22 is deformed by the sealing strip 24 in the sealing position compared to the release position. As a result, the first sealing element 22 rests flat and in a defined manner on the sealing strip 24 . This benefits the sealing effect.

Again 1 can be seen, the first sealing element 22 is designed as a sealing profile and has a hollow chamber 28 . The hollow chamber 28 is delimited by a relatively thin-walled wall area 30 of the first sealing element 22 . The sealing strip 24 rests against the wall area 30 in its sealing position. In the sealing position, the wall area 30 is deformed and pressed into the hollow chamber 28 in relation to the release position. As a result, when the sealing strip 24 is in the sealing position, the wall region 30 abuts not only against an end face 32 pointing forward in the longitudinal direction of the vehicle, but also against side surfaces 34 of the sealing strip 24 pointing in the transverse direction of the vehicle. This achieves a very good sealing effect.

The sealing strip 24 and the first sealing element 22 interact at least in a first sealing region, which extends at least essentially in the vertical direction of the vehicle, in the sealing position of the sealing strip 24 . In the respective end regions of the sealing strip 24 adjoining it in the vertical direction of the vehicle, i.e. on the one hand on the side of the roof frame and on the other hand on the side of the side sill 20, the sliding movement of the sealing strip 24 can be continued by a rotary movement for the respective transitions to the roof frame and to the side sill 20, in order to also to realize advantageous sealing between the sealing strip 24 and the passenger car body 16.

In these end regions on the side of the roof frame and on the side of the side sill 20, the sealing strip 24 is, for example, at least essentially semicircular, in particular sickle-shaped. Alternatively or additionally, it is possible for further sealing strips to be attached to the sealing strip 24 in the vertical direction of the vehicle in the end regions, which are at least essentially semicircular or sickle-shaped and can perform a rotary movement for the transitions to the roof frame and the side skirts 20.

Again 2 As can be seen, the side sill 20 protrudes into the door opening 18 in a transition region 36, in which the side doors 12, 14 adjoin or connect to one another in their closed positions, but without interrupting the door opening 18 or into two separate door openings subdivide. An entry flange 38 of the side sill 20 runs at least essentially in an arc in the longitudinal direction of the vehicle, initially into the door opening 18, extends in a small partial area at least essentially in the longitudinal direction of the vehicle, and then runs out of the door opening 18 again, at least essentially in an arc.

As a result, the side sill 20 has a sill geometry 40 through which a body-mounted sealing triangle 42 with a first sealing surface 44 and a second sealing surface 46 is formed. In the closed position of the front side door 12, the first sealing element 22 is in contact with the first sealing surface 44, so that a very good sealing of the front side door 12 against the passenger vehicle body 16 is achieved. The first sealing element 22 then continues at the top of the sealing triangle 42 in the vertical direction of the vehicle.

The second sealing surface 46 of the sealing triangle 42 is assigned to the rear side door 12 . The rear side door 14 is provided with a third sealing element, in particular a further hose seal, by means of which the rear side door 14 is also sealed against the passenger car body 16 in the closed position. The third sealing element rests against the second sealing surface 46 in the closed position. The sealing strip 24 and the first sealing element 22 , which are then able to interact correspondingly, are then used for sealing, adjoining the sealing triangle 42 upwards in the vertical direction of the vehicle.

For moving the front side door 12 between the open position and the closed position, and more particularly from the closed position to the open position, the front side door 12 is provided with a first door handle. Correspondingly, the rear side door 14 is also provided with a second door handle for moving the rear side door 14 between its closed position and its open position and in particular for moving it from the closed position to the open position. The door handles are used in particular to unlock a respective door lock.

If the side doors 12, 14 are in their closed positions and the door handles are not actuated, then the sealing strip 24 is in its sealing position. If one of the door handles is actuated in order to move the associated side door 12, 14 into its open position, this causes the sealing strip 24 to be displaced from its sealing position into its release position. As a result, the side doors 12, 14 can be opened and closed completely independently of one another.

The coupling between the door handles and the sealing strip 24 is preferably carried out electrically. If one of the door handles is actuated, at least one electrical signal is thereby generated and correspondingly transmitted in order to move the sealing strip 24 from the closed position into the released position by means of at least one actuator.

If the opened side door 12, 14 is closed again, it is detected by means of appropriate sensors that both side doors 12, 14 are in their closed positions and that none of the door handles is actuated. Then, by means of the actuator, the sealing strip 24 is moved from its release position to its sealing position and the side doors 12, 14 are mutually sealed.
