DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

(10) FIG. 1 shows a vehicle, in this case a passenger car but could e.g. also be a utility vehicle, having a roof opening 1 in a fixed roof 2 thereof to be provided with an open roof construction comprising at least one panel 3. The panel 3 is movable for at least partly opening and/or closing the roof opening 1. The panel 3 is movably supported by an operating mechanism 4 (only schematically shown in FIG. 2, but known in the art). The operating mechanism 4 is guided in a guide rail 5 on a frame 6, forming the stationary part, extending along at least one, but here two longitudinal sides of roof opening 1 (FIG. 2). The panel 3 is movable in vertical and longitudinal directions with respect to the roof opening 1. The open roof construction can be of the type whereby the panel 3 slides to an open position at the exterior side of the vehicle body, but it can also be of the type whereby the panel 3 slides to an open position at the interior side of the body.

(11) In the embodiment shown, there is a second panel 7 which is positioned behind panel 3 (when in its closed position) and which in this case is a fixed panel attached to stationary part 4 and permanently closing the respective part of roof opening 1. Panel 3 will be at least partly above panel 7 when in its open position. Panel 7 may also be a movable panel, or may be used as a fixed panel alone, thus permanently covering the whole roof opening 1 and letting light in, not air, at least not by opening it.

(12) FIG. 2 shows the open roof construction in an exploded view, showing panels 3, 7, frame 6 and related parts. Here a sealing assembly 8 is shown which in said view extends along a longitudinal side of the roof opening 1 (along a main part of the longitudinal side edge of panel 7, see also FIG. 3).

(13) In FIG. 4 sealing assembly 8 is shown in more detail. The sealing assembly 8 takes care of the seal between frame 6 and fixed roof 2 and also the seal between panel 7 and frame 6/fixed roof 2. Panel 4 is provided with panel seal 9 which is a bulb seal comprising a mounting member 10 fixing panel seal 9 to an encapsulation 11 around the glass of panel 7. Panel seal 9 cooperates with a first seal part 12 of sealing assembly 8, which is also a bulb seal, and together close a gap between panel 7 and frame 6. Panel seal 9 and first seal part 12 are located above respective guide rail 5 and allow a support of the operating mechanism 4 of panel 3 to pass through the gap that is normally closed by panel seal 9 and first seal part 12 by deformation of panel seal 9 and/or first seal part 12.

(14) Sealing assembly 8 comprises a second seal part 13 also formed as a bulb seal and providing a seal between frame 6 and a vertical edge 14 of fixed roof 2 defining roof opening 1. First and second seal parts 12, 13 are positioned on opposite sides of an upright wall part 15 of sealing assembly 8. This upright wall part 15 includes a reinforcement member 16 providing rigidity to sealing assembly 8 and forming an integral part of an attachment structure 17, in one embodiment formed of a single unitary body, capable of accurately and rigidly attaching sealing assembly 8 to the stationary part, in this case guide rail 5 on frame 6. The attachment structure 17 and reinforcement member may be made from steel, hard rubber or the like, while the softer rubber of the seal parts 12, 13 and any cover may be molded thereon. Reinforcement 16 thus extends between seal parts 12, 13 and below in order to extend to attachment structure 17.

(15) Attachment structure 17 having a horizontal extent or dimension includes hook and clip members 18, 19 and guide rail 5 includes counter parts 20, 21 to lock the hook and clip members to guide rail 5. As mentioned above reinforcement member 16 extends upright, in this case mainly perpendicularly with respect to the horizontal and attachment structure 17 exhibits mainly a horizontal extension. The hook member 18 is positioned at a free end of attachment structure 17 spaced from the reinforcement member 16, while clip member 19 is positioned near the bottom of reinforcement member 16, i.e. at the opposite end of attachment structure 17. The free end of attachment structure 17 is positioned at an upward portion thereof and hook member 18 can be hooked below a horizontal hook of counterpart 20. Opposite clip member 19 extending substantially horizontally can be clipped below a horizontal hook of counterpart 21 on guide rail 5. Counterparts 20, 21 form the upper walls of a gutter-like part of guide rail 5 acting as a drain for any water leaking between second seal part 13 and edge 14 of fixed roof 2. Counterparts 20, 21 can also be formed by recesses in guide rail 5.

(16) FIGS. 5 and 6 show that sealing assembly 8 (the hatched part) can have a larger extent. In FIG. 4 sealing assembly 8 is provided along the complete outer circumference at the rear and side edges of second panel 7, where sealing assembly 8 provides a seal between second panel 7 and edge 14 of fixed roof 2. Panel 9 may be provided along the length of sealing assembly 8, but it is also possible that first seal part 12 of sealing assembly 8 directly seals to encapsulation 11 of second panel 7. In FIG. 6, sealing assembly 8 is provided around the whole inner circumference of roof opening 1, providing a seal to outer circumference of the assembly of panels 3 and 7. Panel 3 may or may not have an additional panel seal to first seal part 12 of sealing assembly 8. Sealing assembly 8 may be the same around the whole circumference. It will be attached to guide rails 5 along the longitudinal sides and attached to similar counterparts on transverse beams along the transverse sides of roof opening 1.

(17) FIG. 7 shows a second embodiment of sealing assembly 8. It includes a third seal part 22. It is positioned near the free end of attachment structure 17 (next to hook member 18) and includes a lip seal the free end of which sealing against the lower side of fixed roof 2. The remainder of sealing assembly 8 is equal to that of FIG. 4.

(18) FIG. 8A shows reinforcement 16 and attachment structure 17 of sealing assembly 8 of FIG. 4 separately. Upright reinforcement member 16 is provided with vertical grooves open at and extending from the upper side of reinforcement member 16. This allows reinforcement member 16 to be bent with less bending force in order to adapt sealing assembly 8 and its reinforcement member 16 and attachment structure 17 to any curvature of guide rail 5 around a horizontal transverse axis. It is also shown in FIG. 8A that hook members 18 and clip members 19 are offset along the length of sealing assembly 8. This also allows sealing assembly 8 to be bent with less force around a vertical axis in the corners of panels 3, 7 in the embodiments of FIGS. 5, 6.

(19) FIG. 8B shows a second embodiment of reinforcement 16 and attachment structure 17 of sealing assembly 8. The interruptions between the parts of hook members 18 are now smaller and the interrupting grooves shorter. Clip members 19 are longer for better bendability.

(20) FIG. 9A shows the rear end of sealing assembly 8 and panel seal 9 in FIG. 2, 3. Encapsulation 11 of second panel 7 becomes broader behind panel seal 9 and sealing assembly 8 smaller. It may include a single seal attached to encapsulation 11 and sealing against the edge 14 of the roof opening 1. A soft rubber molding piece covers the transition from sealing assembly 8 to the panel seal.

(21) In FIG. 9B the front end of sealing assembly 8 and panel seal 9 is shown. They end together with the front end of second panel 7. The sealing assembly 8 and seal may be closed by a rubber molding piece.

(22) From the foregoing it will be clear that the invention provides a sealing assembly in an open roof construction capable of providing an accurate and stable position and therefore sealing quality when built into a vehicle.

(23) The invention is not limited to the embodiments shown in the drawings and described above, which can be varied in different manners within the scope as defined by the appending claims. Aspects of the various embodiments can be used in other combinations.
