Definitions

• the present invention relates to a vehicle roof, comprising an opening, a folding arrangement [3] and a device for accommodating the folding arrangement [3], wherein the folding arrangement [3] has at least 2 lamellae [1] of plastic arranged parallel to one another, the folding arrangement [3 ] for at least partially releasing the opening under folding in a device provided for this purpose [4] can be spent, and wherein the folding assembly [3] in the closed position, the opening completely closes, wherein the slats [1] in the closed position of the opening by a tension are curved and are aligned at least partially releasing the opening substantially flat and plane-parallel.
• sunroofs for vehicles e.g. rigid one-piece, transparent and non-transparent sliding roofs.
• lamella roofs made of transparent materials. These are u.a. in DE 44 15 649 C1 and EP-A-591 644.
• EP-A-1 125 778 describes an openable vehicle roof with at least two, separately openable roof systems arranged one behind the other. A feature of these roofs is that the composite of the individual slats dissolves when opened. Therefore, an additional releasable sealing surface between the individual fins is necessary. This requires complex kinematics (e.g., DE 19959542 A1) and high component stiffness of the single laminations to maintain the sealing force over the life.
• the construction to absorb the sealing forces reduces the transparent viewing area significantly (about 50%) and requires a lot of space, which can affect the freedom of design and aerodynamics in particular.
• the lamella roofs described are still movable only in the vehicle longitudinal axis, since on the one hand the required space when moving along along. the vehicle transverse axis would be too large and on the other hand by the projecting from the vehicle contour slats (or components) strong wind noise can occur.
• integrally connected window blinds made of glass are known (DE 29607921). Such lamellae of glass have a very high rigidity with high weight and low impact strength.
• a vehicle roof having an opening, a folding arrangement [3] and a device for accommodating the folding arrangement [3], wherein the folding arrangement [3] has at least 2 lamellae [1] made of plastic arranged parallel to one another, the folding arrangement [ 3] for at least partially releasing the opening under folding in a device provided therefor [4] can be spent, and wherein the folding assembly [3] in the closed position, the opening completely closes, wherein the slats [1] in the closed position of the opening by a Distortion are curved and are aligned at least partially releasing the opening substantially flat and plane-parallel.
• the vehicle roof according to the invention has a high inherent rigidity without additional stiffening elements. At the same time the smallest possible space is ensured in the open state.
• lamellae [1] and elastomer or hinge is referred to here as a folding arrangement.
• lamellae [1] essentially sheet-like and elongated plates made of plastic such as polycarbonate (PC), polymethyl methacrylate (PMMA, acrylic or Plexiglas).
• the lamellae can also cover the major part, i. usually over 75% and ideally 100% of the lamella sides, by elastomer such as e.g. Polyurethane, thermoplastic polyurethane, or silicone cohesively and / or positively connected.
• tension means that the lamellae are curved relative to the original state. This curvature can be achieved by pressing the lamellae together, e.g. be caused on the lamellar end faces.
• a component is doubly curved (spherical)
• the rigidity increases more than with a simple curvature.
• the rigidity of a component increases when it is under tension.
• the rigidity of a roof can be increased by a double curvature and the application of a bias.
• This fact is ideal for slatted roofs, because when closed, they are comparable with conventional panoramic roofs and must ensure high rigidity.
• This can be realized via 3-dimensional curvatures.
• a curvature in the vehicle longitudinal axis is determined by the vehicle geometry, the curvature transverse to the direction of travel can be realized by the distortion or compression of the slats.
• the tension dissolves continuously during the opening process, preferably dissolves continuously. This reduces the curvature when opening, so that the lamellae are flat parallel to one another only in the largely or fully opened state.
• the lamellae should fill the smallest possible installation space, and this can be done especially for bonded and / or form-locking lamellas Curvature be a hindrance, since the convex / concave unfolded fins would repel each other. In the state of the open louvered roof, therefore, flat slats are to be preferred.
• the lamellae [1] are flat and plane-parallel Fig. 01 - 03.
• curved means a rounding deviating from the straight line in one or two dimensions, i. usually vehicle longitudinal and transverse direction. Preferred is a curvature with a radius of 1, 5 to 4 m, more preferably 2 to 3m.
• substantially flat means that the lamellae are absolutely flat in the geometric sense, or preferably are not absolutely flat, but have a slight "pre-curvature” to ensure that the lamellae later curve in the correct direction the lamellae are absolutely flat or have a curvature with a radius between infinity and 4 m, more preferably between infinity and 8 m.
• the expression “substantially plane-parallel aligned” means that the lamellae are arranged absolutely parallel to one another in the geometric sense or have a deviation from the parallelism of less than 10, preferably less than 5, particularly preferably less than 2%.
• the term “closed position” means that the vehicle roof is closed by moving apart of the slats [1] substantially rainproof.
• the bias voltage can be realized according to the invention in that the guide rails [2] converge in the vehicle longitudinal axis and diverge in the area of the device for receiving the folding arrangement [3] in such a way that the lamellae are largely returned to the original state (see FIGS. 01-03).
• Such a course may preferably be biconcave-shaped [4].
• the slats When closing the roof, the slats are compressed and it forms a curvature.
• the fact that the guide rails are curved along the vehicle geometry, a double curvature is achieved on the curvatures of vehicle geometry and lamellae.
• the lamellae are in a closed state under a tension, so that the roof has a high rigidity. This results, for example, in the curvature as shown in Fig. 07 as [5].
• the middle fins are most curved, Fig. 06 to 08. Nevertheless, the roof can of course be reinforced with reinforcing materials as needed.
• the guide rail [2] may consist of a deep plane and another flat plane, which run one behind the other.
• One behind the other means that there is a front and a back plane, both planes running parallel to each other along parts of the roof skin.
• the rear plane is arranged so that a long pin can protrude through the front plane and be guided in the rear plane. In the front plane, a shorter pin can be guided at the same time, without being influenced by the rear plane.
• the deployment kinematics may require that at least one element be kept “controlled” and the other "free” to move.
• These levels can be formed via grooves. In these grooves protrude differently shaped pins. about different journal lengths or widths, the course of the pins in the planes of the
• the grooves can also be superimposed. Both levels are parallel to the outer skin (roof skin) until reaching the top compartment, so that the slats [1] can be moved as a continuous surface. Only within the
• Roof box run the levels, for. V-shaped apart, so that, for example, the
• Pins for the deep level continue to run along the roof contour or horizontally to this and the short pins are directed upwards.
• the lamellae can also be unfolded downwards, or centrally, contrary to the illustrations. It is also conceivable that not only the long tenon for the
• Deflection is responsible, as well as the short pin can deflect the slats.
• the levels need not be controlled only over the length of the pins. It is also possible to control the control over different cross sections.
• the fins can be made of e.g. be driven by a chain or a threaded rod.
• the pins themselves represent a translational bearing along the guide rail as well as a rotary bearing about its own axis.
• Lamellar structures are moved, but it is also conceivable that individual not cohesively and / or positively interconnected slats can be moved in this way.
