Description

The invention relates to a Lid arrangement as in the preamble of the claim 1 is specified.

Previously known from the present applicant's earlier Finnish patent application FI 20012465 is a trunk lid assembly which is meant for a convertible provided with a convertible roof. A cap assembly of the type listed in the application FI 20012465 has been grown on a concept car, "The Valmet Coupe Convertible" of the Geneva Motor Show 5th-17th 3. was issued in 2002.

The lid assembly includes a lid that with respect to the body of the convertible between a closed position and an open one first position, the trunk from the rear makes accessible, is pivotable. This is a so-called Trunk lid opening function, with the lid on its rear edge is raised.

Optionally, the lid can be between one closed position and an open second Position that allows a hinged roof from the front of the lid in one in the trunk to sink the provided roof shelf and accordingly to be swiveled out of the mentioned shelf. This is a so-called storage lid opening function, with the lid raised at its leading edge.

The lid is attached to the body Actuating mechanism supported by means of which Lid between the closed position and either the first or the second position can be pivoted. The operating mechanism includes a front bar, the upper end of which by a first joint is pivotally mounted on the lid. The actuating mechanism further comprises a Rear rod, the upper end of which is covered by a second Joint at a distance from the first joint is pivotally mounted. The lower end of the rear bar is on the body or one in terms of Body immovable structure pivoted. A swivel rod is attached to the through a third joint Body or one with respect to the body of the Convertible immovable structure swiveling stored. The lower end of the front bar is through a fourth joint swiveling on the swivel rod stored. With the trunk lid opening function act both the front bar and the rear bar than the lid together as one Articulated quadrilateral mechanism when the swivel rod by holding means is held immovably, and the lid can between the closed position and the open first Position can be pivoted. With the storage lid The swivel rod is opened by means of a Control device around a third joint pivoted, the actuating mechanism Pentagonal mechanism is that by an between the swivel bar and the rear bar Connection element must be checked. Here there are however, the problem with the trunk lid Opening function the opened first position of the Lid is such that it is over the open one Trunk lies and therefore when opening the lid any rainwater on the lid in can trickle the trunk. For that is the one above Trunk remaining open lid an obstacle when loading luggage into the trunk.

Different cover arrangements are also in the patents US 5,823,606, US 6,092,335, US 6,250,707 and US 6,293,605.

The The trunk lid is opened by actuation of the parallelogram mechanism, and opening the Cover to expose the shelf is done by Swiveling the subframe, the Trunk lid actuation mechanism does not open the Lid is used. The mechanism of the The trunk lid is completely above the Subframe mechanism. The problem with this version is one complex structure that includes many parts. In addition, many locking devices for Lock the parts to each other and to the body of the car. In the closed position of the The linkages of the mechanisms are located on the cover a place where the widest part of the folded down Roof.

The patent US 6,250,707 describes a lid assembly that also has a subframe used. The lid is through a front Articulated quadrilateral mechanism on the subframe and the subframe through a rear quadrilateral mechanism on the Body of the car supported. In the The trunk lid opening function becomes the front one Quadrangular joint mechanism and at the Storage lid opening function uses the rear four-bar mechanism. The have front and rear quadrilateral mechanisms a common swivel rod. The problem with this Solution is that the mechanism is complicated Structure is and includes many parts. In addition are many locking devices for locking the Parts on each other and on the body of the car needed. In the closed position of the lid the linkages of the mechanisms are on one Place where the widest part of the folded roof lies.

In the patent US 6,092,335 a Cover arrangement listed in which the front and Trailing edges of the lid with locks with the Body of a convertible are connected. If want to use the trunk lid function, locked the locks of the front edge of the Lid and unlocked the rear locks so that the rear end can be raised. Corresponding you can lift the front end if you have the locks the articulation of the rear edge locked. The problem this solution is significant Restrictions on the design of the roof and the Rear part of the car. This is the structure difficult to seal. When used as Trunk lid goes through the front edge of the lid rear part of the hood. To be functional, this solution would need the pivot point the trunk lid except the Body surface or at the front end of the link hinge embarrassed.

In US 6,293,605 a Lid arrangement listed in which the lid through a triangular joint mechanism on the body a convertible is supported. In this Mechanism is linked to the front edge of the lid the body so designed that the lid on the Slide rails laid in the longitudinal direction of the carriage is movable, which pushed the lid back are allowed to move the roof into one with the trunk connected tray can be sunk and lifted out of it allow. The problem with this solution is that it significant design restrictions the roof and the rear of the car. There the lid must be slidable slightly to the rear to have the roof sunk, too Slide rails relatively far to the rear stretch. Because the car gets narrower towards the back and the rails are laid in the sliding direction of the cover the rails can be a significant one Restriction on the width of the roof represent.

In US 6 193 300 the Trunk lid using a scissor mechanism actuated. If you press the lid to the Storage lid opened and the roof sunk too leave, you move the trunk lid on it Front edge using the same trunk lid mechanism, but the front hinge of the lid is unlocked while only the other, rear hinge point of the Mechanism remains locked. With this actuation the lid is moved separately at its rear edge, by placing the lid around one provided there Hinge sliding mechanism swivels. That closed the Trunk lid is on this hinge sliding mechanism locked. In this version, too complicated structure a problem.

It is the object of the invention, a Improvement to that in the application FI 20012465 listed lid arrangement, what improvement continue to have the same advantages with respect to those in the above-mentioned patents Cover arrangements have and also a greater variation in Movement path of the lid would enable produce. It is the intention in the Trunk lid function the lid when lifting the rear edge considerably further forward in the open first position to be pivoted, whereby the water more easily drained from the lid and the Trunk can be loaded more easily.
