Abstract Sliding roof for automobiles having a lid slidably guided in a roof opening on lateral guides, which lid can be raised outwards with the assistance of drive means acting on it, can be displaced relative to the roof opening with simultaneous change of its inclined position after the outward raising, and in its displacement is situated with its rear region over the rear, fixed surface.

Sliding roof for automobiles This invention relates to a sliding roof for automobiles, comprising a lid slidably guided on lateral guides in a roof opening, wh;ch lid can be raised outwards with the help of drive means enyaging on it, after the rais;~ng outwards is slidable relat;~ve to the roof opening with simultaneous change to its inclined position, and during its sliding is situated with its rear region over the rear, fi~ed roof surface.
Sliding roofs of this type are sometimes also known as upper ridge sliding roofs. In one known roof of this type 10 tDE-PS 958,620~, the lid is equïpped with a plurality of sliding or rolling elements on each side at or near the forward edge, which engage in curved, lateral, fixed guides in the roof opening. The curved guides have the effect, during the opening displacement of the lid, that its rearward end is raised above the roof skin and is gradually brought into an inclined position which becomes progressively steeper towards the rear. The result of this is that the lid, as the width of the gap between the forward edge of the roof opening and the forward edge of the lid increases, projects increasingly 20 further above the fixed roof surface of the automobile, so that the wind resistance of the lid increases with increasing size of opening.
The air resistance coefficient of the vehicle, which influences directly the fuel consumption, is thereby also increased. Also, the known lid tends, when pushed far out, to vibrate and causes considerable wind noise when the vehicle is running.

The drive means acting on the lid of the known sliding roof consist of a threaded spindle, journalled rotatably but axially fixed in the centre of the vehicle, which co-operates with a threaded nut fixed to the lid and can be driven by a flexible shaft. On account of the central position of the threaded spindle, the raised up lid is supported only in its longitudinal central plane, so that it is not given suffic-ient stability. Also, the central threaded spindle in the roof opening is readily visible. The same is true also for the flexible shaft, which when a winding crank is provided in the vicinity of the dashboard, more or less divides the windscreen into two.
The task underlying the present invention is, by contrast, to provide a sliding roof constructionl which even at the maximum possible opening displacement of the lid does not lead to any substantial deterioration in the air resistance coef-ficient, which makes possible a firm, low-oscillation position of the opened lid, which is quiet in operation and for which the drive means are not disturbingly apparent.
According to the present invention, there is provided a sliding roof for an automobile~ comprising a lid slidably guided on a frame defining a roof opening, lateral guides fixed relative to the frame, on which the lid is slidably guided, and drive means capable of acting on the lid, which lid can be raised outwards with the assistance of the drive means acting on it, can be slidingly displaced relative to the frame with a simultaneous change of its inclined position after the outward raising, and in its sliding displacement is ,.~. . ~
l ~ ~'7~
situated with its rear region in use over a rear, fixed roof surface of the automobile, wherein (a) the lid is journalled and pivotally movable in the vicinity of its forward edge, (b) raising-out elemen~s are disposed at a fixed location relative to the frame in the vicinity of the rear end of the roof opening, said raising-out elements being such that the height thereof can be changed, (c~ the lid i5 guided dis-placeably on the raising-out elements, and (d~ the raising-out elements are connected at both lateral sides of the frame to the drive means for operation thereby, as the lid is slidably displaced such that the elements continuously change their height relative to the roof opening in such a manner that the angle of inclination relative to the roof opening of the lid during its opening slidable displacement decreases and during its closing slidable displacement increases.
In the sliding roof of this invention the raising-out elements, on account of the way they are mounted and formed, ensure that the lid, in each of its slid positions, projects only so far above the fixed vehicle roof as is necessary for a contactless relative displacement between the lower side of the lid and the rear, fixed roof surface. On account of the arrangement of the raising~out elements in the vicinity of the rear edge of the roof opening, the lid obtains a firm mounting also in each of its positions~ Since the lid in its slid positions projects only slightly above the roof surface, it adversely affects to only a slight extent the air resis-tance co-efficient of the vehicle and causes also only a slight noise production during travelling. The drive means disposed on both sides of ~he roof opening are not , ~7~
disturbingly apparent towards the outside. Because the lid is slidably guided at its forward edge and at the same time is pivotally journalled in the vicinlty of its forward edge, the lid i5 only hinged in the vicinity of its forward edge during sliding, whereas the positive control of the lid inclined positions is assured by the raising-out elements. In one known vehicle ventilation device (DE-AS 1 050 676), in which the feature (b) is provided, there is a form of roof construction that does not belong to the initially mentioned category, in which the raising-out elements are formed as pivoting levers.
Here, even at the maximum : ::
::
:
, i~ `1 I ~7~8~;
g displacement of the lid towards the rear, only a relatively narrow forward ventilating gap is exposed between the front edge of the roof opening and the front edge of t~e lid. More-over, the raising-out elements constructed as pi~oting levers ensure that the inclined position of the lid increases during the first part of its opening displacement and only there-after decreases, whereas in the sliding roof of the present invention the incl;ned position continuously decreases at the start of the opening displacement.
The term "inclined position" is intended to m-ean in the context of the present application those positions of the lid in which the lid makes a more or less large acute angle with the reference plan~ formed by the sliding plane.
In a preferred embodiment of the invention it is provided that the raising-out elements are known screw telescopes, which are mounted on either side of the roof opening with their inner ends fixed to stationary parts of the rGof and their outer ends to sliding joints which are slidably guided on guide rails situated on the lid. With this arrangement, 20 the screw telescopes undertake the control of the inclined position of the lid in its displacement. The guide rails mounted on the lid and the sliding joints fixed to the outer ends of the screw telescopes ensure positive control of the inclined positions of the lid with accompanying stable support of the lid in every one of its opened positions.
According to a further aspect of the invention, there are provided as drive means two flexible drive threaded cables, guided in a conventional tension and thrust transmitting ~ 167~S3~
manner, in engagemen-t with a drive p;nion and each guided on one side of the roof, which are each ~n en~agement by their thread, until the max~mum possible lid inclined position is reached ~efore commencement of the sliding movement, with a driven pinion journalled on a stationary portion of the roof in the vicinity of the rear edge of the roof opening, which pinion is in geared connection with the associated screw telescop~e. As a result of this arrangement, when t~e drive means are operated ~y hand or motor~ the lid, starting from its 10 closed position in which it is flush with the roof opening, is first raised out o~ the roof surface with its rear edge with simultaneous pivoting about its forward edge until its maximum possible l~d inclined position is reached. When this position is reached, the working engagement between the drive threaded cables and the driven pinions is automatically removed, so that as the dri~e means continue to be actuated, there is no longer any action upon the screw telescopes.
In pursuance of the concept of this invention, it is furthermore provided that, for the sliding movement of the lid, 20 an entraining device i5 attached to each of the two drive threaded cables, which when the maximum possible lid inclined position in the closed position of the lid is reached, comes into engagement with a coupling component connected to the lid, and that two flexible adjusting threaded cables, guided in a tension and compression transmitting manner, are provided, each of which is disposed on one side of the roof parallel to the drive threaded cable situated there, engages ~irmly at its ~orward end on a component connected to the lid at the 8 ~;
- 5a -front, and comes into engagement by its thread with the adjacent driven pinion when the maximum poss~ible lid inclined position is reached in the closed position of the lid.
~ s a consequence of this constructional arrangement, the result is achieved that, as the drive means continue to be actuated after the maximum lid inclined position has been reached, the lid opening displacement takes place accompanied by simultaneous reduction in the inclined position of the lid as a consequence of the action of the adjusting threaded cables 10 in conjunction with the driven pinions. Here, the screw tele-scopes previously screwed out by the dri~e threaded cables during the raising of the lid are driven in the contrary directîon by the adjusting threaded cables, that is they are screwed in.
The arrangement here is such that the engagement between the entraining device and the coupling component still exists also during the closure displacement of the lid and is not removed until the limiting position of the lid closure dis-placement and the ma~imum possible lid inclined position have 20 ~een reached. Starting from this position of the lid, as the dr;ve means continue to be actuated, the lid already situated in its closed position is swung back into its starting position, in which it lies flush in the roof opening.
With advantage the arrangement is such that the driven pinion is coaxial with and rotationally keyed to a gear wheel which is in engagement with a smaller gear wheel, which in turn is coaxial with and rotationally keyed to the associated screw telescope. As a result an upward gear ratio is obtained ~ 1$7~
of the gear connection between the driven pinion and the screw telescope. sy an appropriate selection of the thread pitches on the screw telescope and/or of the transmission ratio between the two gear wheels, the length of travel of the screw tele-scopes can be tuned to the length of sliding of the lid, so that the lid is raised in each of its slid positions only so far as is necessary to achieve freedom from contact between the lower edge of the lid and the rear, fixed roof surface.
In order to ensure that the engagement between the en-10 training dev~ce and the coupling component can be removed onlyin the closed position of the lid, it is of advantage if a spring tongue which releases the entraining device only in the closed position of the lid is provided on the coupling component for the engagement between the entraining device and coupling component. The arrangemenk ma~ here favourably be such that the spring tongue, when the lid is in its closed position, is opposite to a corresponding recess in the lateral lid guide rail. In the decoupling of the entraining device from the coupling component, the spring tongue can therefore ~0 enter this recess, whereas in all other positions of the lid it bears against the lid guide rail in such a manner that the entraining device cannot come out of engagement with the coupling component.
Further details of the invention are explained in more detail below with reference to the drawings illustrating an example of embodiment thereof.

As is apparent from the side views illustrated in Fig.
1 to 3, the lid 1 adopts different inclined positions in its different displaced positions. In the displaced position shown in Fig. 1, the lid 1 is still in the location of its closed position in the roof opening 2. The lid is raised up-wards at its rear edge to the maximum extent, however, so that it adopts its maximum inclined position~ as IS necessary immediately before the commencement of the sliding movement.
n the displaced position of the lid 1 shown in F~g. 2, this lid has already been displaced by about half the sliding travel towards the rear, so that the roof opening 2 is exposed in its forward region. In this position, the lid already has a smaller inclination, which decreases still further as the displacement is continued, by the lower side of the lid 1 approaching the rear fixed roof surface 3. In the maximum slid open position illustrated in Fig. 3~ the lid has achieved its minimum inclination, in which it projects only insignifi-cantly above the rear, fixed roof surface 3. The explained movement characteristic is reversed during the sliding closure of the lid. A suitable construction for achieving the afore-mentioned, desired movement characteristic is described below with reference to the remaining figures. In Fig. 1 to 3, .

reference 4 denotes the windscreen, in order to illustrate the d;rection of travel.
In the position of the parts illustrated in Fig. 4 and 7 the lid l is situated in its closed position inside the roof opening 2. The roof opening 2 is bounded by a surrounding bent over flange 5 of the vehicle roof, referenced generally 6. Firmly connected to the vehicle roof and adjoining the flange 5, there is disposed a sliding roof frame 7, usual in sliding roofs, the lateral frame members of which are wider than its front and rear members. The cross sectional profile of the lateral members of the sliding roof frame can be seen from Fig. 16.
The sliding roof is symmetrically arranged about its longitudinal central axis, so that in the following descrip-tion in conjunction with the drawings, only one side of the roof is explained, although the described elements are each present in pairs.
The lid l is journalled pivotally movable in the vicinity of its forward edge by hinge assemblies, of which one hinge part 8 is fixed to the lid, while the associated hinge part 10, connected to it by the hinge pin 9, is fixed to the forward guide shoe ll, as apparent in more detail, for example, from Fig. 9. A guide rail, oriented in the sliding direction and referenced generally 12, is firmly connected to the lateral member of the sliding roof frame 7. The profile of this guide rail can again be seen in Fig. 16. On the guide flange 13 of this rail, which is oriented inwards with reference to the roof opening 2, the forward guide shoe 11 is 7~8~
guided longitudinally slidable.
On the forward member of the sliding roof ~rame 7, a mounting pla-te 14 is rigidly fixed, to which a tubular support 15 for the mounting of the drive means is attached. The drive means are composed of threaded cables 16 and 17 guided in a tension and thrust-transmitting manner, with which a drive pinion 18, rotatably journalled on the mounting plate 14, is in engagement. The drive pinion 18 can be connected by its drive shaft 19 in known manner to a hand crank device or electric motor drive. In the forward roof region, the drive threaded cables 16 and 17 are guided in tubes 20 and 21, of which in the left region of the roof the tube 21 is connected to a guide duct 22 in the guide rail 12, while the tube 20 on the right side of the roof adjoins a corresponding duct of the guide rail present there. In the left-hand region of the roof, the tube 20 runs straight to receive the free end of the drive threaded cable. On the right hand side of the roof, the tube 21 runs correspondingly straight to receive the free end of the drive threaded cable 17. Rotations of the drive pinion 18 in the one or other rotational direction cause a displacement of the drive threaded cables 16 and 17 in the tubes 20 and 21 and in the ducts adjoining them of the guide rails. The drive threaded cables are connected, in a manner to be explained below, with the raising-out elements disposed stationarily in the vicinity of the rear edge of the roof opening 2.
To explain in more detail the engagement of the d~ive threaded cables and more specifically for the left side of the roof assembly that of the drive threaded cable 17 with the 4 8 ~
associated ra~sing-out element, re~erence is first made to Fig. 8 and 9.
As can be seen from Fig. 9, a guide tube 23 for the drive threaded cable 17 adjoins the guide duct 22 at the rear end of the guide rail 12. The guide tube 23 is conducted through a split housing 24, in which the drive threaded cable 17 is in engagement, through an aperture 25 in the guide tube 23, with a driven pinion 26, which is journalled rotatably in the housi`ng 24 and is connected coaxially and rotationally keyed to a spur wheel 27, likewise disposed in the housing 24. The housing 24 is disposed stationarily with respect to the vehicle roof ~y fixing it to the sliding roof frame lFig. 8~.
The spur wheel 27 engages with a smaller spur wheel 28, which is connected rotationally keyed and concentrically to a screw telescope, referenced generally by the numeral 29.
This screw telescope constitutes the raising-out element for the lid 1 and consists for this purpose of an inner rod 30, an intermediate sleeve 31 and an outer sleeve 32, to which the spur wheel 28 ;`s attached. The aforementioned parts of the screw telescope are connected to one another by mutually engaging threads, as indicated in Fig. 14. Here, the rod 30 carries an external thread, the intermediate sleeve 31 an internal thread and an external thread, and the outer sleeve 32 an internaI thread. Since the rod 30 is non-rotationally attached to a sliding joint referenced generally 33 (Fig. 14), rotations of the outer sleeve 32 induced by the spur wheels 27 and 28 have the effect, according to the rotational - direction, of retracting or extending the screw telescope ~ ~`7~
consistlng of the components 30, 31 and 32.
The sliding joint 33 consists, as illustrated in Fig.
14 in conjunction with Fig. 7, of two lateral guide pieces 34 and 35, which are supported rigidly against each by connecting webs 36. Pivot bearing pins 37, situated co-axially opposite each other, which are attached to a U-shaped pin support 38, penetrate into the guide pieces 34 and 35.
The rod 30 of the screw telescope 29 is rigidly attached to this pin support 38.
The pivot axis formed by the pivot bearing pins 37 permits an adapting of the sliding joint to the different inclinations of the lid while the alignment of the screw telescope remains approximately vertical.
The guide pieces 34 and 35 of the sliding joint 33 serve for displaceably guiding the screw telescope 29 on the lid 1.
For this purpose, as can best be seen again from FigO 7 in conjunction with Fig. 14, two guide rails 40 and 41 are fixed opposite to each other on a lid stiffener 39, the guide pieces 34 and 35 being guided longitudinally slidable on these rails.
In Fig. 4, the guide rails 40 and 41 are not drawn in, in order to clarify the drawing. For the same reasons, represen-tation of the guide rail 12 and of the parts connected there-with has been dispensed with in Fig. 7. As can be seen from Fig. 11 and 13, on the drive threaded cable 17 the helical thread 42, which makes the rack-like engagement with the drive pinion 18 and driven pinion 26, is interrupted, in other words it does not extend over the entire length o~ the drive threaded cable 17. In the maximum raised-out position illustrated in Fig. 10 and 11 of the lid 1, which otherwise is still in an undisplaced position, the helical thread 42 has come out of engagement with the driven pinion 26, so that a further longitudinal displacement of the drive threaded cable 17 towards the right cannot produce any ~urther rotation of the screw telescope, which in this position is fully extended.
Starting from the lid position illustrated in Fig. 10 and 11, the displacement of the lid 1 now takes place as described below.
~s is apparent from Fig. 4 in conjunction with Fig. 6, an entraining device 43 is attached to the drive threaded cable 17, this entraining device penetrating through a slit 44 of the tube 21. During the raising out actuation of the screw telescope 29, the entraining device 43 moves freely in the slit 44 towards the guide rail 12. In the position of the lid illustrated in Fig. 10 and 11, i.e. in the maximum inclination position, the entraining device 43 strikes a coupling component, referenced generally 45, and fixed to the guide shoe 11. If the drive is continued, i.e. as the threaded cable 17 moves further towards the right, the en-training device 43 travels into a seating chamber 46 of the coupling component 45, a spring tongue 47 which bounds the seating chamber 46 at the bottom being pivoted elastically downwards into a recess 48 of the guide rail 12. As soon as the entraining device 43, with continuing driving, strikes against the inner wall of the coupling component 45, a continued actuation of the drive results in the sliding dis-placement of the pivoted out lid 1. The sliding movement is J~
limited in the vic~nity of the rear edge of the roof opening by a stop 49 (Fig. 13), which is fixed to the sliding roo~
frame 7 and lies in the movement path o~ the guide shoe ll.
In the closure displacement, the drive threaded cable 17 is displaced towards the left. In this phase, the entraining device 43 bears against a projection 50 of the spring tongue 47, which on account of its resting against the guide rail 12 over the entire sliding travel cannot deflect downwards, 50 that the coupling between the entraining device 43 and the coupling component 45 is maintained during the closure displacement. ~nly when the position of the lid illustrated in Fig. lO and ll is reached, can the spring tongue, as the drive is continued, i.e. as the entraining device 43 continues to move towards the left, deflect into the recess 48. The entraining device 43 then runs over the projection 50 and pivots the spring tongue 47 downwards. The spring tongue 47 strikes at the front against the forward face of the recess 48 (Fig. 10) and thus marks the termination o~ the closure ~liding displacement of the lid 1.
The continuous change in the height position of the lid 1 during the sliding movements of the lid is carried out with the assistance of the screw telescope 29 in the following manner. In the gulde rail 12 there is situated, opposite to the guide duct 22, a second guide duct 51 in which an adjusting threaded cable 52 is guided longitudinally dis-placeable in a tension and thrust transmitting manner. The adjusting threaded cable 52 running parallel to the drive ; threaded cable 17 is fixed at its forward end by an entraining ~ ~G~g~
device 53 fixed thereto to the guide shoe 11, so that as the lid slides this cable moves together with the lid and thus slides in the guide duct 51. The adjusting threaded cable 52 also penetrates movably into a guide tube 54, which similarly to the guide tube 23 is conducted through the housing 24 and adjoins at its forward end the guide duct 51 of the guide rail 12. Inside the housing, at the location of the driven pinion 26, the guide tube 24 also possesses an aperture 55, through which the adjusting threaded cable 52 can come ~nto engagement with the driven pinion 26. As is apparent from Fig. 9, the free end of the adjusting threaded cable 52 likewise possesses no helicalthread, so that in the situation of the components illustrated in Fig. 8 to 11, no force-transmitting working engagement exists between the adjusting threaded cable 52 and the driven pinion 26. At the commencement of the sliding opening movement of the lid, however, the helical thread on the adjusting threaded cable 52 comes into engagement with the driven pinion 26, which at this instant no longer engages in the helical thread of the drive threaded cable 17. The adjusting threaded cable 52, due to its engagement with the driven pinion 26, can therefore drive the spur wheel gear 27, 28 and thus the screw telescope 29. The adjusting of the screw telescope 29 produced in this way is carried out in such a manner that the screw telescope shortens during the opening displacement of the pi`voted out lid, as a result of which the inclined position of the lid becomes less as the opening in the roof increases. During the closure sliding of the lid, by contrast, i ~ ~7~
- :L6 -the screw telescope 29 is driven in the sense of an extension, so that the inclined position of the lid again increases with increasing closure of the roof opening.
Instead of the adjusting threaded cable 52, which executes essentially a straight-line movement, a rigid toothed rack could also be used, for the guiding of which a second guide duct in the guide rail would not be necessary. In this case, certainly, the toothed rack would not be guided as illustrated for example in Fig. 11 with a curved path through the housing 24, but would run straight. The symmetrical configuration of the housing 24 illustrated in the drawings permits its use on the right or left side.
Sliding roof for automobiles This invention relates to a sliding roof for automobiles, comprising a lid slidably guided on lateral guides in a roof opening, wh;ch lid can be raised outwards with the help of drive means enyaging on it, after the rais;~ng outwards is slidable relat;~ve to the roof opening with simultaneous change to its inclined position, and during its sliding is situated with its rear region over the rear, fi~ed roof surface.
Sliding roofs of this type are sometimes also known as upper ridge sliding roofs. In one known roof of this type 10 tDE-PS 958,620~, the lid is equïpped with a plurality of sliding or rolling elements on each side at or near the forward edge, which engage in curved, lateral, fixed guides in the roof opening. The curved guides have the effect, during the opening displacement of the lid, that its rearward end is raised above the roof skin and is gradually brought into an inclined position which becomes progressively steeper towards the rear. The result of this is that the lid, as the width of the gap between the forward edge of the roof opening and the forward edge of the lid increases, projects increasingly 20 further above the fixed roof surface of the automobile, so that the wind resistance of the lid increases with increasing size of opening.
The air resistance coefficient of the vehicle, which influences directly the fuel consumption, is thereby also increased. Also, the known lid tends, when pushed far out, to vibrate and causes considerable wind noise when the vehicle is running.

The drive means acting on the lid of the known sliding roof consist of a threaded spindle, journalled rotatably but axially fixed in the centre of the vehicle, which co-operates with a threaded nut fixed to the lid and can be driven by a flexible shaft. On account of the central position of the threaded spindle, the raised up lid is supported only in its longitudinal central plane, so that it is not given suffic-ient stability. Also, the central threaded spindle in the roof opening is readily visible. The same is true also for the flexible shaft, which when a winding crank is provided in the vicinity of the dashboard, more or less divides the windscreen into two.
The task underlying the present invention is, by contrast, to provide a sliding roof constructionl which even at the maximum possible opening displacement of the lid does not lead to any substantial deterioration in the air resistance coef-ficient, which makes possible a firm, low-oscillation position of the opened lid, which is quiet in operation and for which the drive means are not disturbingly apparent.
According to the present invention, there is provided a sliding roof for an automobile~ comprising a lid slidably guided on a frame defining a roof opening, lateral guides fixed relative to the frame, on which the lid is slidably guided, and drive means capable of acting on the lid, which lid can be raised outwards with the assistance of the drive means acting on it, can be slidingly displaced relative to the frame with a simultaneous change of its inclined position after the outward raising, and in its sliding displacement is ,.~. . ~

situated with its rear region in use over a rear, fixed roof surface of the automobile, wherein (a) the lid is journalled and pivotally movable in the vicinity of its forward edge, (b) raising-out elemen~s are disposed at a fixed location relative to the frame in the vicinity of the rear end of the roof opening, said raising-out elements being such that the height thereof can be changed, (c~ the lid i5 guided dis-placeably on the raising-out elements, and (d~ the raising-out elements are connected at both lateral sides of the frame to the drive means for operation thereby, as the lid is slidably displaced such that the elements continuously change their height relative to the roof opening in such a manner that the angle of inclination relative to the roof opening of the lid during its opening slidable displacement decreases and during its closing slidable displacement increases.
In the sliding roof of this invention the raising-out elements, on account of the way they are mounted and formed, ensure that the lid, in each of its slid positions, projects only so far above the fixed vehicle roof as is necessary for a contactless relative displacement between the lower side of the lid and the rear, fixed roof surface. On account of the arrangement of the raising~out elements in the vicinity of the rear edge of the roof opening, the lid obtains a firm mounting also in each of its positions~ Since the lid in its slid positions projects only slightly above the roof surface, it adversely affects to only a slight extent the air resis-tance co-efficient of the vehicle and causes also only a slight noise production during travelling. The drive means disposed on both sides of ~he roof opening are not , ~7~
disturbingly apparent towards the outside. Because the lid is slidably guided at its forward edge and at the same time is pivotally journalled in the vicinlty of its forward edge, the lid i5 only hinged in the vicinity of its forward edge during sliding, whereas the positive control of the lid inclined positions is assured by the raising-out elements. In one known vehicle ventilation device (DE-AS 1 050 676), in which the feature (b) is provided, there is a form of roof construction that does not belong to the initially mentioned category, in which the raising-out elements are formed as pivoting levers.
Here, even at the maximum : ::
::
:
, i~ `1 I ~7~8~;
g displacement of the lid towards the rear, only a relatively narrow forward ventilating gap is exposed between the front edge of the roof opening and the front edge of t~e lid. More-over, the raising-out elements constructed as pi~oting levers ensure that the inclined position of the lid increases during the first part of its opening displacement and only there-after decreases, whereas in the sliding roof of the present invention the incl;ned position continuously decreases at the start of the opening displacement.
The term "inclined position" is intended to m-ean in the context of the present application those positions of the lid in which the lid makes a more or less large acute angle with the reference plan~ formed by the sliding plane.
In a preferred embodiment of the invention it is provided that the raising-out elements are known screw telescopes, which are mounted on either side of the roof opening with their inner ends fixed to stationary parts of the rGof and their outer ends to sliding joints which are slidably guided on guide rails situated on the lid. With this arrangement, 20 the screw telescopes undertake the control of the inclined position of the lid in its displacement. The guide rails mounted on the lid and the sliding joints fixed to the outer ends of the screw telescopes ensure positive control of the inclined positions of the lid with accompanying stable support of the lid in every one of its opened positions.
According to a further aspect of the invention, there are provided as drive means two flexible drive threaded cables, guided in a conventional tension and thrust transmitting ~ 167~S3~
manner, in engagemen-t with a drive p;nion and each guided on one side of the roof, which are each ~n en~agement by their thread, until the max~mum possible lid inclined position is reached ~efore commencement of the sliding movement, with a driven pinion journalled on a stationary portion of the roof in the vicinity of the rear edge of the roof opening, which pinion is in geared connection with the associated screw telescop~e. As a result of this arrangement, when t~e drive means are operated ~y hand or motor~ the lid, starting from its 10 closed position in which it is flush with the roof opening, is first raised out o~ the roof surface with its rear edge with simultaneous pivoting about its forward edge until its maximum possible l~d inclined position is reached. When this position is reached, the working engagement between the drive threaded cables and the driven pinions is automatically removed, so that as the dri~e means continue to be actuated, there is no longer any action upon the screw telescopes.
In pursuance of the concept of this invention, it is furthermore provided that, for the sliding movement of the lid, 20 an entraining device i5 attached to each of the two drive threaded cables, which when the maximum possible lid inclined position in the closed position of the lid is reached, comes into engagement with a coupling component connected to the lid, and that two flexible adjusting threaded cables, guided in a tension and compression transmitting manner, are provided, each of which is disposed on one side of the roof parallel to the drive threaded cable situated there, engages ~irmly at its ~orward end on a component connected to the lid at the 8 ~;
- 5a -front, and comes into engagement by its thread with the adjacent driven pinion when the maximum poss~ible lid inclined position is reached in the closed position of the lid.
~ s a consequence of this constructional arrangement, the result is achieved that, as the drive means continue to be actuated after the maximum lid inclined position has been reached, the lid opening displacement takes place accompanied by simultaneous reduction in the inclined position of the lid as a consequence of the action of the adjusting threaded cables 10 in conjunction with the driven pinions. Here, the screw tele-scopes previously screwed out by the dri~e threaded cables during the raising of the lid are driven in the contrary directîon by the adjusting threaded cables, that is they are screwed in.
The arrangement here is such that the engagement between the entraining device and the coupling component still exists also during the closure displacement of the lid and is not removed until the limiting position of the lid closure dis-placement and the ma~imum possible lid inclined position have 20 ~een reached. Starting from this position of the lid, as the dr;ve means continue to be actuated, the lid already situated in its closed position is swung back into its starting position, in which it lies flush in the roof opening.
With advantage the arrangement is such that the driven pinion is coaxial with and rotationally keyed to a gear wheel which is in engagement with a smaller gear wheel, which in turn is coaxial with and rotationally keyed to the associated screw telescope. As a result an upward gear ratio is obtained ~ 1$7~
of the gear connection between the driven pinion and the screw telescope. sy an appropriate selection of the thread pitches on the screw telescope and/or of the transmission ratio between the two gear wheels, the length of travel of the screw tele-scopes can be tuned to the length of sliding of the lid, so that the lid is raised in each of its slid positions only so far as is necessary to achieve freedom from contact between the lower edge of the lid and the rear, fixed roof surface.
In order to ensure that the engagement between the en-10 training dev~ce and the coupling component can be removed onlyin the closed position of the lid, it is of advantage if a spring tongue which releases the entraining device only in the closed position of the lid is provided on the coupling component for the engagement between the entraining device and coupling component. The arrangemenk ma~ here favourably be such that the spring tongue, when the lid is in its closed position, is opposite to a corresponding recess in the lateral lid guide rail. In the decoupling of the entraining device from the coupling component, the spring tongue can therefore ~0 enter this recess, whereas in all other positions of the lid it bears against the lid guide rail in such a manner that the entraining device cannot come out of engagement with the coupling component.
Further details of the invention are explained in more detail below with reference to the drawings illustrating an example of embodiment thereof.

As is apparent from the side views illustrated in Fig.
1 to 3, the lid 1 adopts different inclined positions in its different displaced positions. In the displaced position shown in Fig. 1, the lid 1 is still in the location of its closed position in the roof opening 2. The lid is raised up-wards at its rear edge to the maximum extent, however, so that it adopts its maximum inclined position~ as IS necessary immediately before the commencement of the sliding movement.
n the displaced position of the lid 1 shown in F~g. 2, this lid has already been displaced by about half the sliding travel towards the rear, so that the roof opening 2 is exposed in its forward region. In this position, the lid already has a smaller inclination, which decreases still further as the displacement is continued, by the lower side of the lid 1 approaching the rear fixed roof surface 3. In the maximum slid open position illustrated in Fig. 3~ the lid has achieved its minimum inclination, in which it projects only insignifi-cantly above the rear, fixed roof surface 3. The explained movement characteristic is reversed during the sliding closure of the lid. A suitable construction for achieving the afore-mentioned, desired movement characteristic is described below with reference to the remaining figures. In Fig. 1 to 3, .

reference 4 denotes the windscreen, in order to illustrate the d;rection of travel.
In the position of the parts illustrated in Fig. 4 and 7 the lid l is situated in its closed position inside the roof opening 2. The roof opening 2 is bounded by a surrounding bent over flange 5 of the vehicle roof, referenced generally 6. Firmly connected to the vehicle roof and adjoining the flange 5, there is disposed a sliding roof frame 7, usual in sliding roofs, the lateral frame members of which are wider than its front and rear members. The cross sectional profile of the lateral members of the sliding roof frame can be seen from Fig. 16.
The sliding roof is symmetrically arranged about its longitudinal central axis, so that in the following descrip-tion in conjunction with the drawings, only one side of the roof is explained, although the described elements are each present in pairs.
The lid l is journalled pivotally movable in the vicinity of its forward edge by hinge assemblies, of which one hinge part 8 is fixed to the lid, while the associated hinge part 10, connected to it by the hinge pin 9, is fixed to the forward guide shoe ll, as apparent in more detail, for example, from Fig. 9. A guide rail, oriented in the sliding direction and referenced generally 12, is firmly connected to the lateral member of the sliding roof frame 7. The profile of this guide rail can again be seen in Fig. 16. On the guide flange 13 of this rail, which is oriented inwards with reference to the roof opening 2, the forward guide shoe 11 is 7~8~
guided longitudinally slidable.
On the forward member of the sliding roof ~rame 7, a mounting pla-te 14 is rigidly fixed, to which a tubular support 15 for the mounting of the drive means is attached. The drive means are composed of threaded cables 16 and 17 guided in a tension and thrust-transmitting manner, with which a drive pinion 18, rotatably journalled on the mounting plate 14, is in engagement. The drive pinion 18 can be connected by its drive shaft 19 in known manner to a hand crank device or electric motor drive. In the forward roof region, the drive threaded cables 16 and 17 are guided in tubes 20 and 21, of which in the left region of the roof the tube 21 is connected to a guide duct 22 in the guide rail 12, while the tube 20 on the right side of the roof adjoins a corresponding duct of the guide rail present there. In the left-hand region of the roof, the tube 20 runs straight to receive the free end of the drive threaded cable. On the right hand side of the roof, the tube 21 runs correspondingly straight to receive the free end of the drive threaded cable 17. Rotations of the drive pinion 18 in the one or other rotational direction cause a displacement of the drive threaded cables 16 and 17 in the tubes 20 and 21 and in the ducts adjoining them of the guide rails. The drive threaded cables are connected, in a manner to be explained below, with the raising-out elements disposed stationarily in the vicinity of the rear edge of the roof opening 2.
To explain in more detail the engagement of the d~ive threaded cables and more specifically for the left side of the roof assembly that of the drive threaded cable 17 with the 4 8 ~
associated ra~sing-out element, re~erence is first made to Fig. 8 and 9.
As can be seen from Fig. 9, a guide tube 23 for the drive threaded cable 17 adjoins the guide duct 22 at the rear end of the guide rail 12. The guide tube 23 is conducted through a split housing 24, in which the drive threaded cable 17 is in engagement, through an aperture 25 in the guide tube 23, with a driven pinion 26, which is journalled rotatably in the housi`ng 24 and is connected coaxially and rotationally keyed to a spur wheel 27, likewise disposed in the housing 24. The housing 24 is disposed stationarily with respect to the vehicle roof ~y fixing it to the sliding roof frame lFig. 8~.
The spur wheel 27 engages with a smaller spur wheel 28, which is connected rotationally keyed and concentrically to a screw telescope, referenced generally by the numeral 29.
This screw telescope constitutes the raising-out element for the lid 1 and consists for this purpose of an inner rod 30, an intermediate sleeve 31 and an outer sleeve 32, to which the spur wheel 28 ;`s attached. The aforementioned parts of the screw telescope are connected to one another by mutually engaging threads, as indicated in Fig. 14. Here, the rod 30 carries an external thread, the intermediate sleeve 31 an internal thread and an external thread, and the outer sleeve 32 an internaI thread. Since the rod 30 is non-rotationally attached to a sliding joint referenced generally 33 (Fig. 14), rotations of the outer sleeve 32 induced by the spur wheels 27 and 28 have the effect, according to the rotational - direction, of retracting or extending the screw telescope ~ ~`7~
consistlng of the components 30, 31 and 32.
The sliding joint 33 consists, as illustrated in Fig.
14 in conjunction with Fig. 7, of two lateral guide pieces 34 and 35, which are supported rigidly against each by connecting webs 36. Pivot bearing pins 37, situated co-axially opposite each other, which are attached to a U-shaped pin support 38, penetrate into the guide pieces 34 and 35.
The rod 30 of the screw telescope 29 is rigidly attached to this pin support 38.
The pivot axis formed by the pivot bearing pins 37 permits an adapting of the sliding joint to the different inclinations of the lid while the alignment of the screw telescope remains approximately vertical.
The guide pieces 34 and 35 of the sliding joint 33 serve for displaceably guiding the screw telescope 29 on the lid 1.
For this purpose, as can best be seen again from FigO 7 in conjunction with Fig. 14, two guide rails 40 and 41 are fixed opposite to each other on a lid stiffener 39, the guide pieces 34 and 35 being guided longitudinally slidable on these rails.
In Fig. 4, the guide rails 40 and 41 are not drawn in, in order to clarify the drawing. For the same reasons, represen-tation of the guide rail 12 and of the parts connected there-with has been dispensed with in Fig. 7. As can be seen from Fig. 11 and 13, on the drive threaded cable 17 the helical thread 42, which makes the rack-like engagement with the drive pinion 18 and driven pinion 26, is interrupted, in other words it does not extend over the entire length o~ the drive threaded cable 17. In the maximum raised-out position illustrated in Fig. 10 and 11 of the lid 1, which otherwise is still in an undisplaced position, the helical thread 42 has come out of engagement with the driven pinion 26, so that a further longitudinal displacement of the drive threaded cable 17 towards the right cannot produce any ~urther rotation of the screw telescope, which in this position is fully extended.
Starting from the lid position illustrated in Fig. 10 and 11, the displacement of the lid 1 now takes place as described below.
~s is apparent from Fig. 4 in conjunction with Fig. 6, an entraining device 43 is attached to the drive threaded cable 17, this entraining device penetrating through a slit 44 of the tube 21. During the raising out actuation of the screw telescope 29, the entraining device 43 moves freely in the slit 44 towards the guide rail 12. In the position of the lid illustrated in Fig. 10 and 11, i.e. in the maximum inclination position, the entraining device 43 strikes a coupling component, referenced generally 45, and fixed to the guide shoe 11. If the drive is continued, i.e. as the threaded cable 17 moves further towards the right, the en-training device 43 travels into a seating chamber 46 of the coupling component 45, a spring tongue 47 which bounds the seating chamber 46 at the bottom being pivoted elastically downwards into a recess 48 of the guide rail 12. As soon as the entraining device 43, with continuing driving, strikes against the inner wall of the coupling component 45, a continued actuation of the drive results in the sliding dis-placement of the pivoted out lid 1. The sliding movement is J~
limited in the vic~nity of the rear edge of the roof opening by a stop 49 (Fig. 13), which is fixed to the sliding roo~
frame 7 and lies in the movement path o~ the guide shoe ll.
In the closure displacement, the drive threaded cable 17 is displaced towards the left. In this phase, the entraining device 43 bears against a projection 50 of the spring tongue 47, which on account of its resting against the guide rail 12 over the entire sliding travel cannot deflect downwards, 50 that the coupling between the entraining device 43 and the coupling component 45 is maintained during the closure displacement. ~nly when the position of the lid illustrated in Fig. lO and ll is reached, can the spring tongue, as the drive is continued, i.e. as the entraining device 43 continues to move towards the left, deflect into the recess 48. The entraining device 43 then runs over the projection 50 and pivots the spring tongue 47 downwards. The spring tongue 47 strikes at the front against the forward face of the recess 48 (Fig. 10) and thus marks the termination o~ the closure ~liding displacement of the lid 1.
The continuous change in the height position of the lid 1 during the sliding movements of the lid is carried out with the assistance of the screw telescope 29 in the following manner. In the gulde rail 12 there is situated, opposite to the guide duct 22, a second guide duct 51 in which an adjusting threaded cable 52 is guided longitudinally dis-placeable in a tension and thrust transmitting manner. The adjusting threaded cable 52 running parallel to the drive ; threaded cable 17 is fixed at its forward end by an entraining ~ ~G~g~
device 53 fixed thereto to the guide shoe 11, so that as the lid slides this cable moves together with the lid and thus slides in the guide duct 51. The adjusting threaded cable 52 also penetrates movably into a guide tube 54, which similarly to the guide tube 23 is conducted through the housing 24 and adjoins at its forward end the guide duct 51 of the guide rail 12. Inside the housing, at the location of the driven pinion 26, the guide tube 24 also possesses an aperture 55, through which the adjusting threaded cable 52 can come ~nto engagement with the driven pinion 26. As is apparent from Fig. 9, the free end of the adjusting threaded cable 52 likewise possesses no helicalthread, so that in the situation of the components illustrated in Fig. 8 to 11, no force-transmitting working engagement exists between the adjusting threaded cable 52 and the driven pinion 26. At the commencement of the sliding opening movement of the lid, however, the helical thread on the adjusting threaded cable 52 comes into engagement with the driven pinion 26, which at this instant no longer engages in the helical thread of the drive threaded cable 17. The adjusting threaded cable 52, due to its engagement with the driven pinion 26, can therefore drive the spur wheel gear 27, 28 and thus the screw telescope 29. The adjusting of the screw telescope 29 produced in this way is carried out in such a manner that the screw telescope shortens during the opening displacement of the pi`voted out lid, as a result of which the inclined position of the lid becomes less as the opening in the roof increases. During the closure sliding of the lid, by contrast, i ~ ~7~
- :L6 -the screw telescope 29 is driven in the sense of an extension, so that the inclined position of the lid again increases with increasing closure of the roof opening.
Instead of the adjusting threaded cable 52, which executes essentially a straight-line movement, a rigid toothed rack could also be used, for the guiding of which a second guide duct in the guide rail would not be necessary. In this case, certainly, the toothed rack would not be guided as illustrated for example in Fig. 11 with a curved path through the housing 24, but would run straight. The symmetrical configuration of the housing 24 illustrated in the drawings permits its use on the right or left side.
