Abstract

The motor vehicle (1) has a body (3) with a cover part (4) i.e. boot lid, and supported over a laterally lying and arc-shaped arms (6). The arms are movable held at the body, and are shifted to the body for opening or closing the cover part along a trajectory (K) whose path is beside and parallel to restricted guidance devices (8) along which the arms are displaced. The restricted guidance devices are formed by connecting members to which a holding unit is contacted. The holding unit is moved to the arms along an extension.

Description

The The invention relates to a motor vehicle with at least one movable up and to move Cover part of the body, over Arms which are movably held on the body, can be supported, according to the preamble of claim 1.

It is known by many vehicles, such as trunk flaps over two lateral, lying in their front and curved in the arms, the reach under a parcel shelf, at a joint around a vehicle transverse axis pivotally supported on the vehicle body. By The shape of the arms are often such supports as goosenecks hinges designated. they allow a high and wide swinging the trunk lid, without that These collide at their front edge with a rear roof closure would.

Especially In convertible vehicles, this type of connection can be problematic be where the pivot joints for the arms would have to be often a roof storage room for the open one Roof whose extension requires a considerable width, so that there is no room for the said swivel joints on the sides remains.

Of the Invention is based on the problem, even for vehicles with such difficult spatial conditions a tilt-free and movable with the desired trajectory To allow connection of a cover part.

The Invention solves this problem by a convertible vehicle with the features of the claim 1. Advantageous embodiments and developments of the invention are in the further claims 2 to 12 indicated.

According to the invention, that for movable support of the arms next to and parallel to these located forced guidance facilities are provided along which the arms to open or close the Cover part along a trajectory are displaced, the course The movement of the arms uniquely determined even without an end-joint specified. The arms can thereby only on the cover part on the one hand and on the positive guidance devices on the other hand, without being an additional Connection to the body requires. The positive guidance device can be designed in this way be that they are at the most appropriate point of the Armverlaufs attacks, so for example completely outside a roof receiving space can lie.

Provided The arms in side view describe a circular arc and on a this imaging positive guidance device held, the movement of the lid part can be exactly like the Connection to a simple swivel joint done without a however, such a joint would be necessary. on the other hand are also other gradients the arms and the restraint devices possible, so that the opening movement for example, an overlay can be from a rotational and translational movement.

A simple training provides that the arms, for example, a tubular Cross-section or similar form a simple profile and the restraint devices respectively encompass at least one backdrop into those reaching out from the arms Holding means, such as welded Axle stub, intervene.

Around additionally a big opening way to enable and yet the backdrop in relation to longitudinal extension to train the poor for a short time, It is helpful if the holding means on the arms along their Extension are movable.

alternative to the outside scenery can also the arms over their course each have their course following grooves, in the outside each several heads of the Urging means to intervene to effect a forced control. The arms can, for example, as Extruded profiles be formed.

Also can be a guide allows the arms be without these provided with grooves or expansive approaches have to be. Therefor can the forced operation device in each case several an arm over-outside or subordinate leadership roles include. In particular, you can single of these leadership roles be biased in the sense of contact with the respective arm.

Especially Advantageously, at least one of the guide heads or rollers has a tooth profile on, that on a complementary Tooth profile of the arm is unrolled. This is on the one hand slip prevents and even drive the movement of this forced operation device directly negotiable.

Also without the drive function, such a toothing is advantageous, if the guide heads or rollers provided therewith both sides of the vehicle a co-rotating shaft are interconnected. This is one torque support achieved at about a one-sided high load on the cover part, for example, a clumsy manual slamming, a tilting prevents and takes the other side.

Such a lid part can in particular ei NEN trunk lid form. Alternatively or additionally, the cover part in the closed position can cover at least a large part of a receiving space for a convertible roof. Also in two openings - on the one hand to release a passage opening for the roof and on the other hand to release a loading opening for luggage openable lid part, as it is often found in vehicles with fixed shelves, so-called Retractable Hardtops (RHTs), both on his front as well as additionally or alternatively be formed on its rear connection advantageous in the manner according to the invention.

Further Advantages and features of the invention will become apparent from the drawing schematically illustrated and described below embodiments the subject of the invention.

In the drawing shows:

1 a schematic side view of the rear portion of a motor vehicle according to the invention, here in training as a convertible vehicle, with a closed roof and closed (drawn) or opened (dimmed) cover part, and

1a a section along the line II in 1 .

2 a similar view as 1 but of an alternative embodiment having a groove within the arms and constraining means engaging therein,

2a a section along the line II-II in 2 .

3 a similar view as 1 but a further alternative alignment with a tooth profile on the outside of the arms and toothed positive guidance devices engaging therewith,

3a an outlined view from the direction of arrow III in 3 .

4 two detail views of an alternative embodiment of arms, in which retroactively acting and spring-loaded rollers - similar to in 1 - attack as spring-loaded restraint devices,

5 a similar design as in 3 in which the positive guidance devices of both sides are connected to one another via a shaft coupling them,

6 a similar design as in 5 in which the positive guidance devices on both sides are connected to one another via a shaft and a drive acting on them,

7 a similar design as in 6 but with an additional hydraulic drive for moving the lid part and a combination of toothed and non-toothed guide rollers.

The motor vehicle according to the invention 1 , which is shown in the drawing only in the rear area and only schematically, is here as a convertible vehicle with a movable and rear side in the body 3 removable roof 2 educated. It may, as indicated in the illustrated embodiments, be both provided with at least one rear seat four- or multi-seat vehicle and a two-seater. The notchback training shown is not mandatory.

The cabriolet vehicle 1 has in its rear region a here in itself rigid and a total of movable cover part 4 on; this can form at least a boot lid and - unlike shown - also altogether oblique or almost vertical. Next, the lid part 4 in double function for at least partially covering a receiving space for the opened roof 2 be provided as well as to cover a luggage space. The lid part 4 can for a low weight, for example, plastic or metal sheets, possibly in combination with foam materials exist.

Also, for example, at least one further movable cover part 5 , designed here in the manner of a parcel shelf, be provided.

The lid part 4 can in a first opening sense to release a front end region adjacent to its passage opening for the roof 2 and be movable up in a second opening direction for releasing a loading opening for its luggage which is adjacent to its rear end area. Here, only one is provided for releasing a loading opening for luggage opening or closing movement. This movement is according to the drawing a pure pivoting movement, which is not mandatory.

The lid part 4 is over at least two laterally relatively far outboard and therefore spaced apart in the vehicle transverse direction arms 6 . 6a . 6b opposite the body 3 kept movable. In the closed position, it can be pushed onto elastic sealing lines. To this movable Liche support of the arms 6 . 6a . 6b and possibly their drive (see below) to allow these arms 6 . 6a . 6b not at a fixed Swivel joint or other multi-joint construction of the body to be held, but can be displaceable along a trajectory - here a circular segment - a total of. The poor 6 . 6a . 6b are themselves formed circular segment. Depending on the type of movement, it is also possible to use a different shape and a different trajectory, for example an ellipse or an at least partially translatory displaceability.

With the invention, during the up or Zubewegung the lid part 4 the poor 6 . 6a . 6b also be completely movable, and no part of these must be fixed to the body 3 be held.

As exemplary for all drawn embodiments in 1 can be seen, are when swinging the lid part 4 the poor 6 shifted upwards in the direction of the arrow K, so that their end stops 7 be moved from their far into the trunk projecting position rearward and upward on the circular path K. At the end of the opening movement are the end stops 7 then directly or indirectly below positive guidance devices 8th showing the trajectory of the arms 6 pretend. The open version is provided with parenthesized reference numerals.

Also other body flaps, such as side covers of roof openings, can movable according to the invention be.

In the first embodiment according to 1 these are forced guidance devices 8th through several in front of and behind the here tubular arms 6 arranged pressure rollers 12 educated. These lie with their axes of rotation 10 in front of and behind the circular path K to move the arms 6 - And are thus arranged even on this parallel circular paths. The pressure of these arms 6 over and under-taking roles 12 , several of which are arranged one after the other along the trajectory, can, for example, via the force of one or more spring (s) 9 be achieved, of which in the schematic view 1 for the sake of clarity only one is shown. In 4 are also shown by way of example various other spring arrangements. A Federbeaufschlagung sure on the one hand a quiet run, on the other hand it allows against fixed support of the rollers 12 a compensation of manufacturing tolerances or instantaneous torsions in the vehicle, such as when it is one-sided on a curb.

alternative could here too not drawn - forced-circulation devices each by at least one lateral and curved backdrop be formed in the extending from the arms holding means, for Example stub axle, intervene.

Also could such holding means on the arms 6 be movable along its extension, in particular, if at the same time a driving force to be imparted to the arms.

In a further embodiment of the 2 and 2a includes the positive guidance device 8a again in each case a plurality of successively and axially parallel guide heads 12a , These, however, reach into the arms 6a associated and its course following groove 11a and are so far fixed in their position that the course of this groove 11a the trajectory of the arms 6a certainly. A spring acting on the forced operation device 8a may in turn be provided, even such, these only one-sided on a wall of the groove 11a allow to act.

In particular, in the versions of the 3 and 5 to 7 is shown that at least one of the guide heads or rollers 12b a positive guidance device 8b may have a tooth profile on a complementary tooth profile of the respective arm 6b is unrollable. Such training is basically in the above versions after the 1 and 2 imaginable. This is a very accurate and slip-free leadership of provided with the tooth profile arms 6b allows.

In particular, this solution can also be used to transmit a driving force from the guide rollers 12b on the arms 6b Find use like this in 6 is shown. Here is the leader on one 12b transverse connecting shaft 13 an electric motor 14 arranged the shaft 13 - And associated with this leadership heads 12b - Rotationally drives and thereby the movement of the cover part 4 over the arms 6b achieve or at least support. Instead of a drive 14 would also be a pure damper possible, with external drives, for example, the in 7 drawn hydraulic cylinder 15 , can work together.

Even without its own drive or damper 14 may have serrated guide heads or rollers 12b both sides of the vehicle via a rotating shaft 13 be connected with each other, as in 5 is shown. Here is the wave 13 As with a torsion bar only to forcibly synchronize the arm movements of both vehicle sides with each other, thereby tilting when opening or closing the lid part 4 to avoid. In place of the wave 13 can also be provided a push-pull train.

In 7 is also shown that example wise only the front wheels 12b can be toothed and with a complementary toothing on the front of the arms 6b interact while on the back the smooth guide rollers 12 as in 1 are effective as an abutment.

In any case, the leading arms 6 . 6a . 6b always a total of moving on a fixed path and do not require their own fixed connection, such as a swivel joint, to their movable bracket relative to the body 3 , A fixed pivot point was thus replaced, which also means a mounting advantage, since the fixed pivot point is usually difficult to access and the guide devices shown here ( 8th . 8a ; 8b ) easily accessible tightly under the open lid part 4 lie.

The roof 2 In particular, a retractable hardtop (RHT) may also be formed with a plurality of successive plate parts which are rigid in themselves or have at least one respective rigid frame.
