Description

The Invention / innovation relates to a linkage arrangement for a Top compartment lid for a convertible vehicle.

Such a linkage that carries a top compartment lid, for example, is made DE 196 50 402 A1 known. It follows that a top compartment lid of a rear-side receiving space for accommodating an open folding top is provided and the top compartment lid in a conventional manner from a closed position into a pivoted open position can be transferred. For storage of the top compartment cover two support rods are provided on each side of the vehicle, which form a four-bar linkage on both sides for the pivotable mounting of the top compartment lid.

Of the known top compartment lid is on a separate, only on driving the top compartment lid acting drive device, wherein a locking device is provided with the the separate drive device for the top compartment cover over a separate drive train interacts.

A Although such device is highly functional, due to the many but separately to be mounted components but time-consuming, as far as the mounting.

Out DE 195 25 587 C1 also shows a linkage arrangement for a top compartment lid, which has two support arms for storage of the top compartment lid. Also in this known solution, a locking device is known, which interacts positively between the top compartment lid on the one hand and a body-mounted receiving element. This locking device must be mounted separately during assembly of the top compartment unit.

Of the Invention is based on the object, a linkage arrangement with the features of the preamble of claim 1 in such a way that it is easier is to be mounted, does not require separate drive unit and a optionally to be provided locking device in a simple manner can be realized. This task is characterized by the characterizing Features of claim 1 solved, advantageous developments emerge from the subclaims.

When Essence of the invention / innovation it is considered that a between the motor-driven hood frame and at least one of the support arm a transfer link is arranged, through which when opening and closing the Hood a positively controlled opening and closing movement transferable to the top compartment lid is. The advantages achieved by the invention are mainly to see that through the coupling of the movement of the top linkage with the support links the top compartment lid a separate drive for the movement of the top compartment lid is dispensable. As a result, the structural complexity is reduced because only one drive unit needed becomes. Another advantage of the coupling of the hood linkage with the support rods of the top compartment cover a transfer link Is that it is no synchronized vote separate drive units for the hood frame and the top compartment lid needs. Thus, on microswitch to Queries the position of the top compartment lid are omitted whereby the sources of error are reduced. Finally will by providing only one drive a smaller space for the Activation of the top compartment lid and the top linkage needed.

In Advantageously, the transfer link at its pointing in the direction of travel end a body-side mounted Be arranged drive lever, in its central region with the top linkage, for example via a Koppellenker is operatively connected. Such a arranged drive lever allows by its body-side storage a kinematically favorable movement translation while the transmission of forces starting from the motor-driven convertible top linkage the support arms of the top compartment lid.

in the Meaning of an additional function can be provided that on the transfer link rotatable a particular hook-like locking element of a Locking device for the top compartment lid is mounted, the hook end of a on a support links arranged securing pin engages over and the locking hook at the hook end opposite End has a control knob, the movement of the transfer link a stationary arranged control circuit scans in phases. Due to the purely mechanical coupling of the top movement and the movement of the transfer link relative to a safety pin or the control circuit is achieved that both the movement of the top linkage, the movement of the top compartment lid, as well as the movement of the Locking hook for the soft top compartment lid by a the top linkage driving Drive unit allows becomes. This mechanical coupling eliminates incorrect conditions.

Likewise, a reversed arrangement of hooks, pins and link elements within the locking device in the context of open beard invention. Thus, it may be provided, for example, to arrange the control link on the rotatably mounted on the transfer link locking element and to arrange the control circuit scanning control cam fixed to the body, as well as the hook member in the region of a support arm and the engaging with the hook element securing pin rotatable on the transfer link to provide a stored locking element. The locking element, which is preferably designed as a locking hook, has a dual function. On the one hand, it serves to guarantee a positive locking with the securing pin. On the other hand, the control circuit is scanned by means of the integrally formed on the locking element Steuernoke phase and thus easily achieves a steady movement of the connecting hook receiving locking element and finally realized the control of the connecting hook.

The Control Noke can be used either as e.g. final radius of the locking element or but as a substantially perpendicular to the locking element protruding engagement pin may be formed. In the latter case exist the advantages in that the needed Space is further reduced and the designers more freedom of design granted because the control element controlling the locking element in an outside transferred to the plane of extension of the component lying plane can be.

Advantageous it is also the locking element or the locking hook to pretension by a spring element. By such a bias on the one hand, a steadily defined position of the locking element guaranteed and on the other hand, the risk of rattling by a disengage standing locking element avoided.

In an advantageous embodiment is the transfer link facing away from the hood frame Area on a support arm both rotatable and translationally mounted. Such Storage can, for example, by a run in a slot pin be achieved because a rotational movement is always possible and as long the pin is not in an end position of the slot is also a translatory movement possible is.

By the provision of a region-wise translational displacement of the transfer link relative to a support arm the top compartment lid, the construction of the locking hook with lower requirements (more generous play and tolerances) will be realized. The translational mobility of the transfer link can for example, to open of the locking hook can be used while the support arm or the top compartment lid still remains in its closed position.

Especially In addition, it is advantageous to provide a start-up curve and a U-shaped area within the control gate, the U-shaped area with his opening in Direction of the top compartment lid opening movement is aligned. The orientation of the U-shaped opening in the direction of the top compartment lid opening movement let yourself by explaining that one the Insides of the U-shaped Range at least partially acting control of the Locking hook itself after pivoting the locking hook and thus the release of the top compartment lid, the further movement of the transfer link not allowed to interfere.

A further advantageous measure it is in the field of storage of the transfer link to a support links to arrange a pawl that locks the slot in phases or releases. Such a pawl can be arranged so that they Slot at the top compartment lid opening phase always releases and while the top compartment lid closing phase the long hole locks until one of the support lever a defined position in the last third of the closing movement. The Pawl, for example, as rotatable on the transfer link and / or linearly movable and biased by a spring element and / or by its weight force in a rest position persistent U-shaped Angular lever be formed. This pawl inhibits the movement of the in the slot engaging pin such that the pin only one rotational movement To run can. In a translational direction of movement of the pen within of the elongated hole this acts on the pawl on a beveled side, its bevel in coordination with the bias of the pawl or on the pawl acting dead weight is such that by the admission the beveled Side the pawl evades and the pin in the slot a longitudinal movement To run leaves. Becomes the pin from the other, facing away from the chamfered side of the latch Page brought up, so the pawl locks the longitudinal movement of the pin until the top compartment lid or one of the support links a defined, in the range of the last third of the closed position exceeded lying position Has.

By the phased blocking of the oblong hole will cause a hysteresis of the Slot control during the closing process prevented.

The Arrangement of the elongated hole within the transfer link is variable. It is within the scope of the invention, the slot and optionally the pawl at the connection of the transfer link with the Converting the top linkage movement Lever or to provide the displacement of the locking hook on the transfer link.

Drawing figure 1 shows a linkage arrangement for a top compartment lid 1 (schematically with the attachment receptacle 2 shown), which is associated with a rear-side receiving space for accommodating a top and from a closed position A, E in a highly pivoted opening position C and vice versa can be transferred. The linkage assembly comprises at least two support links 3 ' . 3 '' , the body side of a console 4 are rotatably mounted, the opening and closing movement by a drive device (not shown), wherein between the motor-driven convertible top linkage 6 and at least one of the support links 3 ' . 3 '' a transfer link 7 is arranged through which a positively controlled opening and closing movement on the top compartment lid when opening and closing the hood 1 is transmitted.

The transfer link 7 is with its pointing in the direction of the end 8th on a body side mounted drive lever 9 stored in his middle area 10 over a coupling link 11 with the hood frame 6 connected is. As can be seen from the drawing figure 1, are both main link 12 as well as the roof handlebar 13 , the components of the top frame 6 form, as well as the drive lever 9 hinged at a main bearing (not shown).

The drive lever 9 is formed in a preferred embodiment as an angle lever having one end to the main bearing and at the other end to the transfer link 7 is connected and in its middle area 10 over the Koppellenker 11 with the main handlebar 12 the top linkage 6 connected is.

To secure the top compartment lid in its closed positions A and E is on the transfer link 7 rotatable a locking hook 16 a locking device 17 arranged. The locking hook 16 overlaps with its hook end 18 a safety pin 19 , which is preferably arranged on a support arm. On the hook end 18 opposite end of the locking hook 16 is a control cam 20 formed during movement of the transfer link 7 phased a fixedly arranged control circuit 21 scans. According to the drawing figures 3 and 4 is the control circuit 21 at the console 4 arranged. Likewise, from the drawing figures 3 and 4, the control cam 20 as a substantially vertically projecting engagement pin 22 trained, however, is the control cam 20 executed in drawing figure 1 as an end contour of the locking element. For safer control of the locking hook 16 this is biased by a spring element (not shown).

In drawing Figure 2, the movement of the top compartment lid 1 displayed during the top storage. Here, the top compartment lid moves 1 from its closed position A via the transitional position B to its maximum opening position C and from this in turn via the transition position D in its the closed top covering the closed position E. The figures 3 and 4 described below correspond to the positions A and E, respectively 2 ,

From drawing Figure 3 it can be seen that the transfer link 7 on the hood frame 6 remote area on the front support arm 3 ' is both rotatable, and partially mounted translationally. The translational displacement is through a slot in the hood frame 6 opposite end of the transfer link 7 realized, in which a on the front support arm 3 ' arranged pin 25 to be led. This slot allows one for unlocking (arrow 26 ) of the locking hook 16 advantageous linear movement of the transfer link 7 relative to the front support arm 3 ' ,

The control setting 21 has a startup curve 27 and / or a U-shaped entry area 28 on, with the u-shaped engagement area 28 with his mouth 29 in the direction of the top compartment lid opening movement 30 is aligned. Next is in the area of storage of the transfer link 7 with the front support arm 3 ' a latch 31 over the storage point 32 on the transfer link 7 arranged the long hole 24 phased locks or releases. The latch is in the storage point 32 rotatably mounted and biased by a spring element (not shown).

The further details of the latch 31 can be seen in particular from the drawing FIG. According to drawing figure 5 divides the pawl 31 the slot in two sections 33 . 34 , The the section 34 facing surface of the latch 31 has a bevel such that upon application of the inclined surface 35 through the pen 25 the handle 31 against their bias yields and the pin 25 inside the slot 24 can perform a linear motion. During a movement of the pen 25 from the section 33 the pen acts on 25 the straight area 36 the latch 31 and becomes in its linear mobility in the direction of the area 34 as long as inhibited until the latch 31 by a further influence (not shown) starting, for example, from the front support arm 3 ' , is swung out of the slot area and this for the movement of the pin 25 releases.

In the following, with reference to the drawing figures 3 and 4, the locking and unlocking of the top compartment lid 1 be described in his movement. In drawing figure 3, starting from the opening movement of the top linkage 6 the transfer link 7 moved in the direction of the rear of the vehicle. It will be on the front support arm 3 ' arranged pin 25 against the surface 35 the latch 31 moves and gets, starting from the section 34 , in the section 33 , This will cause a linear movement of the transfer link 7 allows the locking hook 16 out of engagement with the safety pin 19 can pass, as during the linear movement of the transfer link 7 the engagement pin 22 of the locking hook 16 in the lower part of the control panel 21 or the U-shaped area 28 remains and by this vertical fixation of the engagement pin 22 a rotational movement of the locking hook 16 according to arrow 26 is reached.

In the further swinging of the top linkage 6 the pen arrives 25 in an end position in the area of the section 33 the long hole 24 and thus the motive force on the front support arm 3 ' transferred, which in turn initiates a pivoting of the top compartment lid.

Starting from drawing figure 4, which corresponds to the movement position D according to drawing Figure 2, it can be seen that despite the pulling movement (in the direction of the vehicle front) of the pin 25 in the section 33 the long hole 24 located. This can be explained by the latch effect, as shown concretely in the above-mentioned paragraph. engagement pin 22 dives into the U-shaped area 28 the control setting 21 one. During the pulling movement of the transfer link 7 is the pulling force on the pawl 31 on the pen 25 and thus on the front support arm 3 ' transferred, in turn, moves the top compartment lid down front. Before the vehicle roof reaches its end position (end position "top closed" or end position "top shelf") the securing pin engages over 19 the hook end 18 of the locking hook 16 , Subsequently, by releasing the locking action of the pawl 31 , triggered by the influence of the front support arm 3 ' on the latch lever 31 and an associated release of the slot section 34 for the pen 25 , A directed toward the vehicle front linear movement of the transfer link 7 allows. With this in the movement process of the hood in one of its end positions concluding linear movement of the transfer link 7 becomes a rotational movement of the locking hook 16 over the safety pin 19 achieved, which locks the top compartment lid.
