DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

(7) Firstly referring to FIGS. 1-3, an example is illustrated of an open roof construction for a vehicle having a roof assembly and comprising a sunscreen assembly in which guides in accordance with the present invention may be incorporated. Said roof assembly is for opening and closing a roof opening 1 in a stationary roof part 2 of the vehicle and includes a movable closure panel 3 which, by means not illustrated in detail but known per se, can be moved for opening and closing said roof opening 1. Commonly, as is known, the movable panel 3 is guided in longitudinal guides mounted in or formed in the stationary roof part 2 along longitudinal sides 12 of the roof opening 1. A user operated device such as a motor or crank (not illustrated) is operably coupled to the panel 3 via cables or the like to move the panel 3 selectively between its open and closed positions. In FIG. 1 the closure panel 3 has been illustrated in a position in which it opens the roof opening 1.

(8) Below the roof opening 1 a sunshade assembly is positioned. Basically, said sunshade assembly comprises a flexible sunscreen 4, a rotatable winding shaft 5 for winding and unwinding the sunscreen 4 at a first transversal edge and two opposite longitudinal guide assemblies 6 and 7. The guide assemblies 6, 7 can be connected to or formed integral from a single unitary body with the guides of the closure panel (not illustrated). Likewise, the guide assemblies 6, 7 can be separate from the guides of the panel 3. Drive members may be provided, which in FIG. 1 have been illustrated schematically by dotted lines 9, 10. As is known per se, the drive members may comprise longitudinal members driven by an actuator 11 for a reciprocating movement for winding and unwinding the sunscreen 4.

(9) Each drive member 9, 10 is connected to an operating beam 8 provided at and connected to a transversal edge of the sunscreen 4 remote from the winding shaft 5. Although the reciprocating movement of the sunscreen 4 primarily is generated by the reciprocating movement of the drive members 9 and 10 as caused by the actuator 11, it is possible too that in addition the winding shaft 5 is preloaded in a sense for winding the sunscreen 4 thereon. Further it should be noted that the movement of the sunscreen 4 also may be initiated manually.

(10) Now, reference is made to FIG. 2 which schematically illustrates a transverse cross section according to II-II in FIG. 1 (it is noted that only the right half of the cross section is shown, the left half being a mirror image thereof). FIG. 2 shows the panel 3, right guide assembly 7 (attached to the stationary roof part 2) and operating beam 8. The sunscreen 4 is attached to the operating beam 8 in a manner known and not further elucidated here.

(11) The guide assembly 7, in the illustrated embodiment, comprises an upper guide 13 and a lower guide 14. The operating beam 8 has attached to its outer end a mounting part 15 which protrudes into the upper guide 13 and which is connected therein to drive member (e.g. cable) 9. Thus, the operating beam 8 comprises opposite lateral ends each extending into a corresponding upper guide 13 and being guided therein. The corresponding longitudinal edge of the sunscreen 4 will be guided in the lower guide 14.

(12) A positioning member 16 (illustrated in FIG. 3) is attached to the operating beam and extends into, and is guided by, lower guide 14. A wing 17 of the sunscreen 4 is folded around said positioning member 16.

(13) Referring to FIG. 3, part of the operating beam 8 near its left end is shown. The guide assembly 7 with upper guide 13 and lower guide 14 have been omitted in this view to more clearly show the positioning member 16. From FIG. 3 it appears that the wing 17 of the sunscreen 4 gradually unfolds in a direction towards the winding shaft 5. When, in a fully or partially closed position of the sunscreen 4, a longitudinal edge thereof comes out of the lower guide 14, the position thereof can be restored by fully opening the sunscreen (winding it onto the winding shaft 5) and again moving it to a (partially) closed position. The wing 17 extending around the lip 16 will take care of again positioning the longitudinal edge of the sunscreen into the corresponding lower guide 14.

(14) FIGS. 4-12 show, in a schematic cross section, embodiments of the lower guide 14 intended for application in a sunshade assembly of the type described above. It is noted, however, that the use of the guide in accordance with the present invention is not limited to such applications, but that its field of application is much wider (and also could extend beyond the automotive field). As will be described below, such guides generally comprise at least two spaced guide legs for defining there between a guide channel for receiving therein and guiding corresponding ones of the opposed longitudinal edges of a sunscreen. Further the guides and longitudinal edges are provided with cooperating guide locking members and edge locking members for preventing the longitudinal edges of the sunscreen from moving out of the guide channels.

(15) Specifically referring to FIG. 4, a guide 14 (preferably made of a metal such as aluminium) is illustrated comprising un upper guide leg 18 and a lower guide leg 19, which at an inner end are connected by a guide bottom 20. A part or insert 21 (in this embodiment made of plastic material) is positioned between the upper guide leg 18 and lower guide leg 19. This plastic part 21 is provided with a ridge or projection 22 acting as guide locking member for cooperation with an inwardly folded part 23 of a longitudinal edge of the sunscreen 4 (illustrated in broken lines in this figure) and acting as edge locking member for preventing the longitudinal edges of the sunscreen 4 from moving out of a guide channel 24 defined within the plastic part 21. Thus, the guide locking members (ridges or projections) 22 are defined on a separate plastic part 21 engaging the guide 14, and not on the guide 14 itself.

(16) As viewed in the longitudinal direction of the guide 14, one single plastic part 21 may be applied extending over the entire length of the guide 14, but as an alternative a number of adjacent plastic part sections may be used too.

(17) The plastic part 21 is spaced from the guide bottom 20 and at least partially is spaced from the upper and lower guide legs 18,19 (for defining a free space 25). Further the plastic part 21 is connected to said upper and lower guide legs 18,19 only at the ends thereof remote from the guide bottom 20. In this embodiment the guide legs 18,19 at their free ends are provided with a protrusion 26 for engagingly locking the plastic part 21 in the guide 14.

(18) In FIG. 5 an embodiment of the guide 14 is illustrated in which the plastic part 21 is attached to the guide bottom 20 (which for that reason is provided with an opening 27, wherein the plastic part 21 is provided with a locking part or pin 28 with enlarged head extending through and locking to said opening 27). In this embodiment the protrusions 26 are spaced from the plastic part 21 (spacing 48) for allowing to cope with production tolerances of the guide 14 (for example as a result of wear of a manufacturing tool).

(19) Now referring to FIG. 6, an embodiment of the guide 14 is shown with a plastic part or insert 21 that is provided with shaped or bent ends 29 for enclosing the free ends 30 of the upper and lower guide legs 18,19 remote from the guide bottom 20. For securely attaching the plastic part 21 to the guide 14 cooperating snapping members (generally indicated by 31) may be provided.

(20) Further, in the embodiment according to FIG. 6, the plastic part 21 is provided with living hinges 32 allowing to manufacture the plastic part 32 in a substantially flat configuration (and folding it to the configuration shown when assembling it with the guide 14).

(21) FIG. 7 illustrates an embodiment in which not a single plastic part, but two separate plastic parts 33,34 respectively are attached to the upper and lower guide legs 18,19. Specifically, the guide bottom 20 connecting the guide legs 18,19 is provided with two recesses 35 for receiving each a first (inner) end of a corresponding one of the two separate plastic parts 33,34. In correspondence with the embodiment of FIG. 6 an opposite second (outer) end of each plastic part 18,19 is provided with a bent end 29 for enclosing the free end 30 of the corresponding guide leg 18,19 remote from the guide bottom 20. Between the first (inner) ends of the plastic parts 33,34 and the bottom (in the figure the leftmost end) of the recesses 35 a free space 36 is provided.

(22) In FIG. 8 the plastic part 37 defines a member only provided at and connected to a free end 30 of the upper guide leg 18. It may be attached thereto by means of a 2K moulding process or any other appropriate means (such as, for example, cooperating snapping members 31 as illustrated in FIG. 6). A guide locking member 38 provided on this plastic part 37 defines a flexible lip protruding into the guide channel 24 for defining an entrance opening into the guide channel 24, and is capable of bending in an inward or outward direction of the guide channel 24 to a position with enlarged entrance opening. As a result an inwardly folded part 23 of the sunscreen is safely kept in the guide channel 24, whereas an enlarged member (for example a positioning member 16 illustrated here in broken lines) may pass by pushing the flexible lip 38 (for example inwardly and upwardly). Such a positioning member 16 may have guide edges (described below with respect to FIGS. 13 and 14) acting as a lead-in for engaging and moving the flexible lip 38 of the plastic part 37 for temporarily enlarging the entrance opening (as defined between the lowermost tip of the flexible lip 38 and the upper surface of the lower guide leg 19) of the guide channel 24 during passage of the positioning member 16.

(23) In the embodiments illustrated in FIGS. 4-7 the lower guide leg 18 is provided with a depression 40 (for example for guiding the positioning member 16), the shape of which is followed by the plastic part 21 or 34. In the embodiment of FIG. 8 it has been indicated that such a depression 40′ also may be dispensed with.

(24) The flexible lip 38 also may be provided in any of the embodiments according to FIGS. 4-7, taking the place of the ridge or projection 22.

(25) FIG. 9 shows an embodiment of the guide 14 in which it is combined with (or is an integral part of) another (main) guide 41 (which for example also may be an upper guide 13 as illustrated in FIG. 2) for guiding any mechanism part 42 (which for example may be a drive member 10 as illustrated in FIG. 2). In this embodiment a plastic part 37 in accordance with FIG. 8 is used, but also a plastic part in accordance with any other embodiment described may be used.

(26) FIGS. 10 and 11 relate to a specific embodiment in which the upper guide leg 18 is shorter than the opposite lower guide leg 19 and wherein the plastic part 43 is positioned in front of a free end 49 of the upper guide leg 18 for defining an entrance opening 44 into the guide channel 24 (between its lowermost tip and the lower guide leg 19). The plastic part 43 is movable in a direction substantially perpendicular to said upper guide leg 18 for enlarging the entrance opening 44 (as illustrated in position 43′) for enabling an enlarged member (such as positioning member 16) to pass, and is biased by a spring member 45 in a direction for decreasing the entrance opening (thus towards the lower guide leg 19).

(27) As illustrated in FIG. 11, such a movable plastic part 43 may be received in a recess 46 in a seal member 47 (that, for example, may cooperate with panel 3) positioned alongside, or (as illustrated here) attached to the guide 14 through integrated guide 41 or 13. The position of the movable plastic part 43 (especially its lowermost position) may be adjustable.

(28) FIG. 12 illustrates an embodiment (which has some resemblance with the embodiment of FIG. 7) wherein the two separate parts 33,34 now are attached to the respective guide legs 18,19 in a manner to be movable in parallel and relative thereto against the bias of biasing members 50. This allows the passage of a positioning member 16 (not illustrated) or other part with larger dimensions than the sunscreen 4 by moving at least one of the parts 33,34 to a position as illustrated in broken lines. Of course, the shapes and dimensions of the cooperating sections of the parts 33,34 (for example shaped or bent ends thereof) and of the guide legs 18,19 (for example the ends 30 thereof remote from the guide bottom 20) must be such that such relative movements are possible.

(29) In FIG. 13A a top plan view of a positioning member 16 in a guide 14 is illustrated schematically. In FIG. 13B a cross section (according to B-B in FIG. 13A) through the guide 14 with positioning member 16 is illustrated. A single movable plastic part 51 (biased by biasing member 50) is provided and the positioning member 16 comprises guide edges 16′ for cooperation with a projection 22 of the part 51 when moving in the guide 14 (compare moved position 22 in full lines of the projection and not disturbed position 22′ in broken lines). Thus the positioning member 16 may pass and after its passage the projection 22 returns to its starting position for safely keeping the sunscreen 4 with its edge in the guide 14.

(30) Likewise in FIG. 14A a top plan view of a positioning member 16 in a guide 14 is illustrated schematically. In FIG. 14C a cross section (according to C-C in FIG. 14A) through the guide 14 with positioning member 16 is illustrated. A part 52 is provided having a flexible lip 53 for cooperation with inwardly folded part 23 of sunscreen 4. As best visible in the side elevational view of FIG. 14B (showing a view according to arrow b in FIG. 14A) the positioning member 16 comprises guide edges 16′ for cooperation with flexible lip 53 when moving in the guide 14. Thus the positioning member 16 may pass and after its passage the flexible lip 53 returns to its starting position for safely keeping the sunscreen 4 with its edge in the guide 14.

(31) The invention is not limited to the embodiments described before which may be varied widely within the scope of the invention as defined by the appending claims.

(32) Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above as has been held by the courts. Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.
