Abstract
A seal for the gap between an edge of a motor vehicle roof opening and an associated lid is constructed as a hollow member (5) formed from an elastomer material. The wall regions (13, 14) facing towards the flange member (6) and frame (8) surrounding the roof opening are relatively thick-walled, whereas the outer wall regions (17, 18) facing towards the lid (4) are relatively thin-walled and are outwardly bulged in the form of a ridge in the uncompressed state. A sealing lip (16) adjoins the fixed roof surface (2) and extends, from here onwards, obliquely upwards to the ridge (20) in the manner of a wind deflector. When the lid is closed, the hollow profile member (5) is so compressed that none of its wall surfaces extends above the external skin of the roof (2) and the lid (4). <IMAGE>
Description
SPECIFICATION
Motor vehicle sliding roof having an edge gap seal member
This invention relates to a motor vehicle sliding roof having an edge gap seal member, the roof having an opening and a lid or lid member associated therewith journalled pivotally in the region of its forward edge about a horizontal axis oriented transversely to the direction of travel and, if necessary, is guided in the raised position laterally in the roof opening displaceable partly over the rear, fixed roof surface, which opening is bounded by a substantially vertical downwardly extending roof flange member extending around all four sides of the opening, to which a roof frame member surrounding the roof opening is attached, an edge gap situated between the edge faces of the lid extending around said all four sides and the substantially vertical downwardly extending roof flange member being sealed when the lid is closed.
The edge gap seal or seal member hereby proposed is preferably used in a sliding roof of the above stated construction, in which the raised lid can be displaced towards the rear over the fixed roof surface. It is, however, suitable not only for such so-called upper ridge sliding roofs, but also for roofs in which the lid, which may indeed be removable, can be raised above the roof surface solely in the manner of a forwardly hinged ventilating flap by raising its rear edge. When, therefore, sliding roofs are referred to below, this designation shall encompass in general all such types of roof construction.
In sliding roofs of the various constructions under discussion, the flattest possible form of construction is desired in the interest of headroom in the cabin. If a pivoting-in wind deflector were to be mounted in the region of the forward edge of the roof opening, as appears logical for upper ridge sliding roofs and removable ventilating flaps, then considerable difficulties are encountered in the housing of a wind deflector of this type having regard to the aforementioned flat construction. A further aspect in the design of sliding roofs of this type is the accommodating of an edge gap seal which shall be as effective as possible.If the lid associated with the roof opening is a transparent lid of a comparatively thin, singlelayer synthetic glass plate or the like, an edge gap seal can be fixed to the lid itself only through the agency of an additional metal frame or by pushing an edge gap seal onto the edge of the lid. In the first case the fixing of the in any case expensive metal frame presents difficulties, whereas in the second case the edge of the lid is outwardly thickened in the manner of a beading by the pushed-on edge gap seal, which in general conflicts with the requirement of a smooth external skin to the automobile or motor vehicle.
Embodiments of the present invention seek to construct and to fit an edge gap seal or seal member that an additional, pivotal-in wind deflector is unnecessary and a reliable sealing in all known lid constructions is achieved.
According to the invention there is provided a motor vehicle sliding roof having an edge gap seal member, the roof having a roof opening and a lid or lid member associated therewith journalled pivotally in the region of its forward edge about a horizontal axis oriented transversely to the direction of travel and, if necessary, in the raised position is guided laterally in the roof opening displaceable partly over the rear, fixed roof surface, which opening is bounded by a substantially vertical downwardly extending roof flange or flange member extending around all four sides of the opening, to which flange a roof frame surrounding the roof opening is attached, an edge gap situated between the edge faces of the lid extending around said all four sides and the substantially vertical downwardly extending flange member of the roof being sealed when the lid is closed, wherein, in the roof opening, a hollow profile member formed from an elastomer material is fixed extending around said all four sides, the wall regions of which facing towards the flange member and the roof frame are relatively thick-walled, whereas the outer wall regions facing towards the lid are relatively thin-walled and, in the uncompressed state, are bulged outwards in the form of a roof as seen in cross-section, the externally situated roof surface adjoining with a sealing lip the fixed roof surface of the motor vehicle and, from here onwards, extending in the manner of a wind deflector obliquely upwards to a ridge zone, which is followed by the internally situated roof surface descending downwards to the roof opening.
The edge gap seal member acts, in the uncompressed state, as a wind deflector projecting above the roof surface which, however, not only is present along the forward edge of the roof opening but surrounds the entire roof opening, with the consequence that the roof opening is protected all around against the penetration of water and incident wind. On account of the easy deformability of the hollow profile member, the edge gap seal member can reliably sealingly adapt to virtually any usual form of the lid edge, when the lid is closed.
With the lid closed, the hollow profile member is pressed in by the lid, the externally situated roof surface being situated approximately in the plane of the fixed roof surface of the automobile and the lid, the ridge zone bearing against the edge faces of the lid, and the internally situated roof surface bearing against the underside of the lid in the edge zone of the lid. With this construction, when the lid is closed, no wall portions of the edge gap seal member project above the surface of the roof and of the closed lid.
The internally situated roof surface may favourably possess peripheral ribs or the like, which bear from below against the closed lid and further improve the sealing effect.
The arrangement is advantageously such that the hollow profile member is fixed by clamping-on onto a fixing flange of the roof frame adjacent to the downward flange of the roof. In this manner a fixing of the edge gap seal member either to the roof opening or the lid is unnecessary. The edge gap seal member can indeed be fitted to the roof frame before it is installed and be installed together with it, which constitutes a substantial simplification of assembly.
A reliable and simple clamping fixing is achieved if the fixing flange of the roof frame is composed of an upwardly oriented rib and a downwardly oriented rib adjoining thereto, of which the upwardly oriented rib engages into a groove of the hollow profile member, which profile member engages with a hookshaped projection around the downwardly oriented rib.
To improve the self-upstanding properties of the sealing profile member, the cavity of the profile member may be filled with an elastic, compressible foam material.
Alternatively, however, a construction is possible, in which the sealing profile member as a whole is formed from an elastic compressible foam material without a cavity, its external surfaces being formed smooth and free from pores.
Further details of the invention will be explained in more detail below with reference to the drawings illustrating an example of embodiment thereof. The drawings show:
Figure 1 in perspective view, the roof of an automobile with installed upper ridge sliding roof, the lid of which is raised and displaced to the maximum towards the rear, and
Figure 2 a section through the edge of the roof opening and the edge gap seal along the line Il-Il in Fig.1.
Fig. 1 illustrates the roof region of the cabin of a passenger automobile, the normal direction of travel of which is indicated by arrow 1.
In the forward region of the fixed automoble roof 2, is situated the roof opening 3, which can be closed by the lid 4. Reference 5 denotes the special edge gap seal 5 surrounding the roof opening 3 and to be explained in more detail below, which seals the lid 4 in its closed position at all sides.
As can be seen from Fig. 2, the roof opening 3 is surrounded by a vertical downward flange 6 of the automobile roof 2, extending around all four sides. The vertical downward flange is adjoined by a flange 7, likewise extending around all four sides, on which the roof frame 8 fixed thereto in a manner not shown is laid.
The roof frame 8 possesses, at its edge towards the vertical downward roof flange 6, an upwardly oriented rib 9 and a downwardly oriented rib 10 adjoining the external wall of the rib 9. The ribs 9 and 10 constitute together, independently of the frame construction, which differs at the different sides of the frame, a fixing flange extending around all sides of the frame for the edge gap seal 5 fixed thereto. For fixing the edge gap seal, this seal fits around the rib 9 by a corresponding groove, not referenced, and fits around the rib 10 by a hook-shaped projection 11.
On the projection 11 is situated also an extension 12, indicated in broken line, which, after the edge gap seal has been fitted, adopts the position shown in full lines between the roof frame 8 and the flange 7 of the automobile roof.
The edge gap seal 5 is, in the example illustrated, constructed as a self-upstanding hollow profile, the wall regions 1 3 and 14 of which towards the fixing flange 9, 10 and the roof frame 8 are constructed thick-walled. The wall region 14 is adjoined by a downwardly oriented, tapering projection 15, which bears against the adjacent side wall of the roof frame 8. The wall region 1 3 terminates in a tapered sealing lip 16, which in the assembled state bears sealingly on the fixed automobile roof 2 and, in the uninstalled state, adopts approximately the position shown in broken line.
The sealing lip 1 6 and the projection 1 5 are adjoined by outer, thin-walled and therefore easily deformable wall regions 1 7 and 18, which, in the uncompressed state, are outwardly bulged somewhat in the form of a roof as seen in cross-section, as indicated by the full lines in Fig. 2. The externally situated roof surface 1 9 adjoining the sealing lip 1 6 here constitutes a wind deflecting surface, which extends, from sealing lip 16, obliquely upwards to a ridge zone 20. The ridge zone 20 continues into the internally situated roof surface 21, from which sealing ribs 22 project. The thick-walled wall regions 1 3 and 14 enclose an obtuse angle and, together with the thin-walled regions 1 7 and 18, bound profile cavity 23.
The edge gap seal 5, formed from an elastomer material, when the lid is closed as indicated by dot-and-dash lines in Fig, 2 adopts the position also shown in dot-anddash line. The externally situated roof surface 1 9 is now situated approximately in the plane of the fixed roof surface 2 and of the lid 4, whereas the internally situated roof surface is situated substantially underneath the lid 4 and bears from below with its sealing ribs 22, deformed by compression, against the edge zone of the lid. The ridge zone 20 bears sealingly against the edge surfaces of the lid.
In raising movements and opening sliding displacements, the edge gap seal 5 stands up in the zones vacated by the lid 4 into the position illustrated in Fig. 2 in full lines and constitutes, with its wind deflector-like, inclined external roof surface 19, a peripheral wind and water deflecting device when the roof is opened (Fig. 1).
