Abstract

The structure has a rear sided body region with a transparent rear window (12). The rear window seals and unblocks a rear opening of the rear sided body region in two states by guiding rails (20). The guiding rails are formed such that the rear window is transferred from one state to another state by a combined translatory and rotatory movement, where the rear window lies horizontally and below a center of the rear opening.

Description

The The present invention relates to a body structure for a vehicle according to the preamble of claim 1.

Such a body structure is for example from the DE 199 61 354 A1 and includes a steeply sloping rear of a combination vehicle, wherein a transparent rear window is slidably mounted such that it closes in a first state provided in a rear door rear opening and is lowered in a second state vertically down into a lower part of the rear door.

A Such Absenkbarkeit the rear window is a very practical Vehicle feature. Especially in the US are a number of vehicle models z. B. the types "station wagon", "SUV" and "Jeep" equipped with it.

adversely is in the known body structure that this is basically a at least approximately level and vertically extending rear window requires so These are in the tailgate sink. In the known technique inevitably creates a more or less "angular" vehicle design, which the vehicles in question often appear unattractive leaves or this special feature of a retractable rear window only for special vehicle types permits. More attractive, especially rounded designs (vehicle types) leave hardly or not at all realized with the known technology.

It It is an object of the present invention to provide a body structure of the type mentioned in terms of freedom of design in the rear of the vehicle to improve.

These Task is solved by a body structure according to claim 1. The dependent claims relate to advantageous developments of the invention.

The Inventive body structure is characterized in that the adjusting device is designed for this purpose is, the rear window in the adjustment from the first state through a combined translational and rotational movement in the second state, in which the rear window is substantially horizontal and below a center the rear opening is located.

The Combination of a translatory and a rotational movement in the rear window adjustment allows a variety of shapes the rear body area, which can not be realized by means of the "sliding technique" mentioned above would. According to the invention is the rear window in the second state advantageously substantially horizontally and below a center of the rear opening.

The inventive design is compatible with rear windows of a three-dimensional or domed, in particular strongly arched Shape. The vehicle design in the rear area must therefore not necessarily consider a more or less flat shape of the rear window.

The at the end of the combined translational and rotational movement, hereinafter also referred to as "combination movement" of the rear window reached, essentially horizontal position allows it advantageous, the feature of a herausführbaren from a rear opening Rear window in many other popular vehicle types. In a preferred use, the body structure according to the invention forms for example, a notchback or hatchback of the vehicle in question, which is then in particular a sedan or a Coupe act can. One for a combination vehicle preferred embodiment provides that the rear window in its second state substantially horizontal and mostly, especially complete within the bounded by the vehicle contour space, for example on a hat rack of the vehicle.

The inventive feature, according to which the rear window in the second state is "below a center of the rear opening" is by no means exclude, that the rear window in this state in the vehicle longitudinal direction fully considered in front of or behind the rear opening lies. Alternatively it can be provided that the rear window in this Condition partly before and partly behind the rear opening lies. For the Practice of particular interest is an embodiment in which the rear window in the second state is at a level which is at least approximately equal the level of a lower rear edge is (or even lower).

Especially to achieve an elegant movement and / or adaptation to a given tail design is an embodiment of advantage, in which the combination movement over much of the Movement course has a rotation component simultaneously to a translation portion.

In a preferred embodiment is provided that a rotational portion of the combination movement has an orientation such that an upper rear window edge moved to the front and a lower rear window edge to the rear becomes.

The Adjustment of the rear window starting from the second state back into the the first state preferably corresponds to one compared to the previously described opening process exactly reverse movement. In this case, the expert a variety of design options for realization the adjusting device available, for this purpose, for example, guide rails and / or handlebars may include.

In a preferred embodiment For example, it is provided that the adjustment on both sides at the rear opening edge running guide rails to the leadership comprising on both sides connected to the rear window sliding elements. These sliding elements can formed in a manner and connected to the rear window, as for example for Adjustment devices of so-called lifting / sliding roofs, outdoor sunroofs (ASD) and spoiler roofs known per se. Also, the rear window and / or the rear opening edge provided with a peripheral edge gap seal (eg profile seal) to be watertight in the first (closed) state the rear body area sicherzu. The sliding elements are in this case z. B. on the inside of the rear window the rear window tethered.

The Rear window can be made of glass or plastic, for example be.

The mentioned above guide rails can z. B. at so-called vehicle pillars (between a lower body area and a roof area, e.g. B. C-pillars one Sedan) or integrated into it. In a vehicle with one in a tailgate or tailgate rear opening may guide rails on a tailgate or Tailgate frame be placed.

Especially for one structurally simple realization of the required combination movement is an execution advantageous in which two pairs of each symmetrical to one Longitudinal central axis the body structure arranged sliding elements are provided.

in this connection can be provided that one of the two pairs of sliding elements is formed by body end of Ausstellhebeln whose distal (rear window side) ends at lateral edge regions the rear window are hinged. Such release lever are in particular advantageous to use in an initial phase of the combination movement at least part of the rear window from the contour surface of the Rear opening "to lift out". This z. B. be provided that in the initial phase of movement lower rear window edge area to the rear and / or an upper one Rear window edge area shifted outwards from the rear opening contour becomes. If the rear window by the combination movement completely before or shifted behind the rear opening contour surface should be, according to one alternative embodiment provided that in the initial Movement phase the rear window in total forward or backward and / or substantially orthogonal to the contour surface of the rear opening is relocated.

Austellhebel can in particular also be used to the rear window in one first (initial) Lift lift off the seal (at least in certain areas). In order to can be achieved that the rear window package when opening no longer "in" the seal moves but more or less contactless moves to the seal. This is special advantageous in terms of the seal wear and the for driving the rear window forces to be expended.

in the Within the scope of the invention, not only such deployment levers are advantageous can be used, the proximate (body side) ends during the Combination movement are moved (such as the above mentioned Out lever). Rather, it can also be provided that the adjusting device alternatively or additionally at least one pair of each symmetrical to a longitudinal central axis the body structure arranged release levers comprises, whose proximal ends are hinged to the body and their distal Ends are hinged to lateral edge regions of the rear window.

In an embodiment is provided that the rear window is a substantially rectangular Contour possesses, with the rear window, however, be curved easily can. In the context of the invention, the rear window even without problems with a comparatively large one bulge be provided. This is in particular a curvature meant in which an "effective Total thickness ", the measured on the disc placed on a flat surface can, advantageously at least 20 times as large as the thickness of the disc material.

The rear window can z. B. be designed as a component manufactured in composite construction. In particular, the rear window - similar to a conventional sunroof cover - from a disc (eg., Toughened safety glass (ESG)) and foamed (foam) reinforcing and / or attachment points may be formed. The latter parts can z. B. plates with cranked Verschraubösen represent, which are suitable for direct screwing of the rear window element to the mechanical parts of the relevant adjustment. In addition, the composite construction makes it possible to achieve an advantageous and simple connection as well as an appealing and / or particularly resistant (finishing) edge optic.

Also it is conceivable that the rear window has a laminated glass of the type in which two disks separated by a plastic film are provided.

In one in particular for Limousines or for coupes particularly interesting embodiment it is provided that the rear window in the second state at least partly behind the rear opening located body section, in particular z. B. a trunk lid, covered. Around this one possible Compact vehicle design with the rear window in the second state can be provided that the shape (curvature) of the Rear window corresponds to the contour of this body section, so that the rear window the body portion with a uniform distance, more or less full cover up " can.

If the rear window in the second (opened) State at least partially located behind the rear opening Cargo or trunk lid covered, it can be provided that the horizontally opened disc, which on the Trunk lid is open when opening the trunk with the trunk lid mitschwenkt. This allows the Access to the trunk even with the rear window open. The Mitverschwenkung The rear window is especially for those body structures easily possible, in which the trunk lid and surrounding the rear opening body sections form a unit (eg in 5-door "hatchback versions" with tailgate). Alternatively it can be provided that the rear window (in a High speed) is automatically transferred to the closed position (first state), once an opening the trunk is tried. For this purpose, z. B. with a the rear window adjusting device associated detection device (eg in the area of a trunk lock or a remote control device for this castle) used to detect an upcoming trunk opening operation become. Such an automatism of the rear window closing process is (to release the trunk lid movement) especially in vehicle types or body structures interesting in which a trunk lid movement not necessarily with a movement of the rear opening connected is.

The Invention will now be described with reference to embodiments with reference on the attached Drawings closer explained. They show:

1 is a perspective view of a vehicle in a state in which a rear window closes a rear opening of the vehicle rear,

2 is one of the 1 corresponding view at partially opened rear opening,

3 is one of the 1 corresponding view with fully opened rear opening,

4 is a schematic side view of the vehicle rear of 1 to illustrate the mechanics used to adjust the rear window

5 is one of the 4 corresponding view according to a further embodiment,

6 is one of the 4 corresponding view according to another embodiment, and

7 is one of the 4 corresponding view according to another embodiment.

The 1 to 3 show a total of 1 designated motor vehicle (coupe) with a body structure comprising a vehicle rear 3 ,

The rear of the vehicle 3 is formed by a subsequent to a roof surface, obliquely sloping back first body section 5 , to which a very flat second body section 6 and finally a very steep third body section 7 followed.

The vehicle shown 1 can thus be dependent on the inclination of the body sections 5 and 6 be referred to as notchback or hatchback coupe.

The body section 6 is formed in the example shown by a trunk lid. Notwithstanding the illustrated embodiment, the body sections 5 and 6 together also form a tailgate swinging outwards and upwards.

The rear of the vehicle 3 points in the first body section 5 a large, approximately rectangular rear opening 10 on, which is formed between the C-pillars of the vehicle and in the state according to 1 from a transparent rear window 12 is closed. In known manner allows the (possibly tinted) rear window 12 due to their transparency, the vehicle occupants a view to the rear.

A peculiarity of the illustrated body structure is that the rear window 12 from the in 1 shown, the rear opening 10 closing condition by means (not shown) adjusting the release of the rear opening 10 in a second (opening) state can be transferred. The adjusting device is in this case designed such that the rear window 12 in the adjustment from the first state according to 1 by a combined translational and rotational movement via an intermediate position according to 2 (Partial opening) and finally further into an end position according to 3 (Full opening) is convertible. In the fully open state is the rear window 12 substantially horizontally at the top of the second body section 6 , In this end position is thus the entire rear opening 10 Approved.

The adjusting device used for the described "combination movement" is connected to a suitable controllable drive, for example comprising an electric motor, which can be operated by the driver of the vehicle by operating corresponding controls in the dashboard at any time (even while driving). Advantageously, therefore, the rear of the vehicle can be 3 optionally open and close, either for purposes of ventilation regulation or to provide a means of loading the interior through the rear opening 10 therethrough.

4 exemplifies the principle of operation of the vehicle 1 used adjusting device.

The adjusting device comprises on both sides at the rear opening edge (on the insides of the C-pillars) extending, arranged symmetrically to a vehicle longitudinal center axis guide rails ("guide rail pair"), of which in the schematic figure only one and with 20 is designated. These guide rails 20 serve to guide both sides of the rear window edge tailed sliders 22-1 and 22-2 , These gliders are symmetrical in pairs on the one hand at the lower rear window edge ( 22-1 ) and on the other hand at the upper rear window edge ( 22-2 ) arranged laterally outwardly projecting.

Although the gliders 22 For the sake of simplicity of illustration in the contour surface of the rear window 12 lying horizontally, so they are in practice expediently offset something to the vehicle interior to less hinder the arrangement of a continuous circumferential edge gap seal (not shown) between the rear window edge and the rear opening edge.

In the illustrated embodiment, the two guide rails extend 20 each backwards to a rear end of the second body section 6 reaching (just above the surface of this body section 6 ). The two guide rails 20 in each case form a continuous guideway, in each case both on one side of the rear window 12 arranged glides 22-1 . 22-2 in the combination movement described below to release the rear opening run.

The combination movement is initiated by a force application of the lower slider 22-1 and / or the upper slider 22-2 , such that the slider pairs 22-1 . 22-2 simultaneously along the common guide rails 20 be moved backwards or downwards.

As it is based on the in 4 shown arrangement is easy to understand, can by this displacement of the slider 22-1 . 22-2 the rear window 12 from their position shown in the intermediate position accordingly 2 and finally to the end position accordingly 3 be transferred to release the rear opening. By reversing the application of force, the rear opening can be opened 10 close accordingly. The movement of the rear window 12 is composed of translatory and rotational components for both actuation directions.

The rear window 12 can be infinitely adjusted. Deviating from the illustrated embodiment, however, could also be provided that the user can only control fixed default rear window positions, z. B. a closing and a (full) opening position.

at The following description of further embodiments are for the same effect Components used the same reference numbers, each supplemented by a small letter to distinguish the embodiment.

there is essentially only on the differences to the or already described embodiments received and incidentally hereby expressly refer to the description of previous embodiments.

5 shows a further embodiment of a body structure, in which, in contrast to the reference to 4 described Ausfüh tion form separate and spaced apart in the vehicle longitudinal direction guide rails 20a-1 and 20a-2 for glider pairs 22a-1 and 22a-2 are provided. Another difference is that the bottom slider 22a-1 in a central area of the lateral edges of a rear window 12a are arranged. The front guide rails 20a-2 have a shown in the closed state of the rear window 12a approximately circular arc around the rear glides 22a-1 extending guide portion, which at the beginning of the combination movement of the sliders 22a-2 is going through. Accordingly, in an initial phase of motion, the combination movement has substantially only one rotational portion with an orientation such that the upper rear window edge is shifted forward and the lower rear window edge is displaced rearward. In a middle phase of motion, a downward translation portion is added. Finally, in an end phase of the combination movement, only translation takes place in the direction of the mutually parallel, lower end sections of the guide rails 20a-1 . 20a-2 ,

6 shows a further embodiment in which, unlike those with respect to the 4 and 5 described embodiments, only an upper pair of sliders 22b-2 in a pair of guide rails 20b is guided, whereas for guiding a central portion of a rear window 12b a arranged on both C-pillars Ausstellhebel 24b is provided. A first, lower end of the two release lever 24b is always included in the vehicle 26b pivoted about a vehicle transverse axis. A second, upper end of each deployment lever 24b is also pivotable about a vehicle transverse axis at the respective lateral edge of the rear window 12b at 22b-1 hinged.

In the combination movement for releasing a rear opening pivots the linkage 22b-1 along the in 6 dashed arrow. At the same time, the upper pair of gliders becomes 22b-2 along the guide rails 20b shifted downwards on a curved guideway. At the end of this movement is the rear window 12b horizontally at the lower rear edge of the rear, with a rear portion of the rear window 12b protruding from the rear opening and just above the second body section 6b is positioned. In this fully open state, the front end portion of the rear window is located 12b Advantageously completely within the considered in the vehicle longitudinal direction width of the C-pillars of the vehicle 1b ,

7 shows a further embodiment in which, unlike those with respect to the 4 to 6 described embodiments, a lower portion of a rear window 12c only relatively little is moved in the combination movement. One at the bottom of the side edges of the rear window 12c arranged slider pair 22c-1 runs here in comparatively short guide rails 20c-1 , In contrast, run front guide rails 20c-2 for holding upper glides 22c-2 arcuately curved over the entire height of the C-pillars of the vehicle in question 1c downward. The resulting combination movement thus has a relatively large proportion of rotation.
