A tilt mechanism is provided at a rear portion (31) of the flexible member (3) so as to tilt up the rear portion (31) thereof in the upward direction and to form at least a clearance between the rear portion (31) of the flexible member (3) and the vehicle roof panel, thereby making sure that passengers in the rear seat can enjoy more comfortable ride in the vehicle. Further, the tilt mechanism, in association with the opening of the front portion (6) of the flexible member (3), tilts up the rear portion (31) of the flexible member (3) to form at least a clearance between the rear portion thereof and the vehicle roof panel (2) when the front portion of the flexible member (3) opens. The rear portion of the flexible member (3) is operatively interconnected with the drive mechanism (18,19,20). The drive mechanism moves the rear portion (31) of the flexible member to the forward direction of the vehicle, thus opening the rear of the roof panel opening (2a) of the vehicle.

Description: DETAILED DESCRIPTION OF THE INVENTION 1. Field of the Invention The present invention relates to a slidable roof device for a motor vehicle. 2. Description of the Prior Art A slidable roof apparatus equipped with a flexible member as a slidable roof to cover a roof panel opening of a motor vehicle wherein the flexible member is openable from the forward to the rearward direction of a vehicle body has been known in the art as disclosed in Japanese Utility Model Application Laying Open Gazette No. 63-40228. However, this type of the slidable roof apparatus opens only the front of the roof panel opening of the vehicle body by opening the flexible member. Therefore, when there are passengers in the rear seat, the flexible member is folded in the rear of the roof panel opening as well as in the overhead portion of the passengers in the rear seat. This means that even if the roof panel opening is opened to the full, the passengers in the rear seat may feel uncomfortable and stifling. Further disadvantage of this apparatus is that, since only the front of the roof panel opening can be opened, there will be no circulation of air flowed into the vehicle from the opening, thus failing to obtain the favorable ventilation. In addition, opening only the front of the roof panel opening may have the result that the vehicle cabin functions as a kind of a resonance box, causing the problem of resonance, or a throb sound. SUMMARY OF THE INVENTION The primary object of the present invention is to provide a slidable roof device for a motor vehicle which can offer passengers in the rear seat a comfortable ride as well as improve the ventilation of the vehicle. To achieve the above-mentioned objects, a slidable roof device for a motor vehicle in the present invention includes the features as described in claim 1. In this invention, the tilt means tilts up the rear portion of the flexible member to make at least a small opening between the rear portion of the flexible member and the vehicle roof panel. Accordingly, passengers in the rear seat will be relieved of the feeling of being stifled in the vehicle. In addition, when opening the front of the roof panel opening by moving the front portion of the flexible member to the rearward direction of the vehicle body, an opening made in the rear portion of the flexible member by the tilt means will be effective in improving the circulation of air and ventilation inside the vehicle cabin. As a result, there will be no stagnation of air inside the cabin, thereby preventing the resonance effect therein. The slidable roof device for a motor vehicle of the present invention is provided with second drive means operatively interconnected with the rear portion of the flexible member through the tilt means. The second drive means activates the tilt means to tilt up the rear portion of the flexible member. This second drive means also opens the rear of the roof panel opening of the vehicle body by moving the rear portion of the flexible member to the forward direction of the vehicle body. In this way, in addition to the front of the roof panel opening of the vehicle body, the rear of the roof panel opening can be opened in the present invention when the rear portion of the flexible member moves to the forward direction of the vehicle. Thus, passengers in the rear seat can enjoy more comfortable ride in the vehicle. The present invention provides the slidable roof device for a motor vehicle wherein the second drive means is operatively interconnected with the first drive means so that the tilt means tilts up the rear portion of the flexible member in association with the opening of the front portion thereof to form at least a small opening between the rear portion of the flexible member and the vehicle roof panel. Accordingly, the tilt means is interlocked with the opening motion of the front portion of the flexible member so as to tilt up the rear portion of the flexible member when the front portion thereof opens. This tilt means creates an opening between the rear portion of the flexible member and the vehicle roof panel. As a result, without any special operation, passengers in the rear seat can enjoy a comfortable ride due to the improved air circulation. In this way, ventilation is facilitated and resonance can be avoided. The device of the present invention includes tilt-up detecting means for detecting the state when the rear portion of the flexible member finished tilting up. The control means receives the output from the tilt-up detecting means to control the second drive means to move the rear portion of the flexible member to the forward direction of the vehicle body after the tilt-up motion. In other words, in the present invention, the rear portion of the flexible member moves to the forward direction due to the operation of the second drive means only after the tilt-up motion finishes. In order to avoid any trouble for a driver and a passenger in the front seat when passengers in the rear seat tilt up the rear portion of the flexible member, the control means in the device, responsive to the output from the tilt-up detecting means, prohibits the activation of the first drive means during the tilt-up motion of the rear portion of the flexible member. Preferrably, the tilt-up detecting means comprises a limit switch. The device further includes lock detecting means for detecting the locking state of the first and the second drive means. The control means, responsive to the output from the lock detecting means, halts the drive control of the first or the second drive means. Accordingly, when the drive means stops activation thereof in the case of a full-opening state or a full-closed state of the flexible member, the drive control of the drive means is ceased, thereby relieving the drive means of the unnecessary overload. The tilt means comprises a mounting bracket provided at the rear portion of the flexible member, a slider connected with the drive means and being movable in the longitudinal direction of the vehicle body, an engaging pin member attached to the slider, and a cam member being provided at the mounting bracket and having a cam groove with which the engaging pin member slidably engages. The engagement between the engaging pin member and the cam groove of the cam member should form a mechanism for tilting up the rear portion of the flexible member. For tilting up the rear portion of the flexible member with a simple configuration, the cam groove of the cam member comprises a horizontal groove portion extending substantially in the horizontal direction, and an inclined groove portion inclinedly and downwardly extending to the forward direction from the front end of the horizontal groove portion. When the engaging pin member travels from the horizontal groove portion to the inclined groove portion, the rear side of the mounting bracket moves to the upper position, thus tilting up the rear portion of the flexible member. Further advantageous embodiments are subject-matter of the dependent claims 10 and 11. The foregoing and other objects, and novel features of the invention will become more apparent upon reading the following detailed description and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail in connection with the accompanying drawings. Referring to Fig.1, reference numeral 1 designates a motor vehicle. A roof panel 2 of the motor vehicle 1 has an opening 2a. This roof panel opening 2a is openably and closably covered with a flexible member 3 (a hood member). More specifically, the flexible member 3 is foldably provided in the longitudinal direction on the vehicle roof panel 2 so as to selects a folded state of opening the roof panel opening 2a or an extended state of closing the opening 2a. Mounted on the vehicle roof panel 2 is a rectangular-shaped frame member 4. Guide rails 5, 5 (refer to Figs.2(a) and (b) ) are provided at the both sides of the frame member 4. Foldably mounted along the guide rails 5, 5 is the flexible member 3 so as to be openable (foldable) in the longitudinal direction of the vehicle body both from the forward or the rearward direction thereof. More closely looking at the front portion of the flexible member 3, as shown in Figs.2(a) and (b), formed at the right and the left side of a front plate member 6 are mounting portions 6a, 6a on which a mounting bracket 7 is fixed by means of bolts 8a and nuts 8b. The mounting bracket 7 includes a base 7a fixed on the mounting portions 6a, 6a, and a supporting portion 7b downwardly extending at the outer periphery of the base 7a. A cam member 9 having a cam groove 9a is secured in the supporting portion 7b. The cam groove 9a includes a front horizontal groove portion 9b extending substantially in the horizontal direction, and a rear inclined groove portion 9c downwardly extending to the rearward direction from the rear end of the horizontal groove portion 9b. A slider 10 having a substantially inverted U-shape in cross section is connected with the mounting bracket 7 by means of an engaging pin 15. This engaging pin 15 slidably engages with the cam groove 9a of the cam member 9. The engaging pin member 15 projects sideward from the upper portion of the slider 10. The end portion of the engaging pin member 15 passing through the cam groove 9a of the cam member 9 is provided with a snap ring 16 whereby the mounting bracket 7 and the slider 10 are connected. The engagement between the engaging pin member 15 and the cam groove 9a of the cam member 9 constitutes a tilt means K for tilting up the front portion of the flexible member 3 at the initial phase of the opening operation. The rear part of the supporting portion 7b of the mounting bracket 7 has, at the lower end thereof, a shoe member 22 which slidably engages with an outside guide groove 5a of the guide rail 5, while the front part of the supporting portion 7b has, at the lower end thereof, an another shoe member 23 which slides on the upper surface of the guide rail 5. Thus, with this arrangement, the front end portion of the flexible member 3 moves upward when the flexible member 3 retreats. The slider 10 slidably engages with an inside guide groove 5b of the guide rail 5 by means of shoe members 24, 24. A guide bracket 11 corresponding to the guide rail 5 is fixed to the slider 10. The guide bracket 11 is also connected with a front drive wire 12 which is located in a housing groove 5c outside the guide rail 5. As shown in Figs.4 through 7, the drive wire 12 engages with a gear 14 which is rotated by a first drive motor 13 locating substantially at the center of the rear side of the frame member 4. Then the drive wire 12 extends inside a front idle cable housing portion 41a, an outer idle cable housing of a cable housing member 41 located below the other guide rail 5. With the rotation of the first drive motor 13, the drive wire 12 opens the front portion of the flexible member 3. As a result, the front of the roof panel opening 2a is opened. Accordingly, when opening the front portion of the flexible member 3, first the slider 10 withdraws and this withdrawal changes the relation of the engagement between the engaging pin member 15 and the cam groove 9a of the cam member 9 so as to restrict the position of the mounting bracket 7. Then the front portion of the mounting bracket 7 moves upward against the slider 10. As a result, the front plate member 6, i.e. the front portion of the flexible member 3 tilts up and then withdraws to open. The rear portion of the flexible member 3 opens in the same manner as the front portion thereof. That means the rear plate member 31, i.e. the rear portion of the flexible member 3 tilts up and then move forward to open the rear of the roof panel opening 2a. More specifically, as shown in Fig.3(a), (b), a mounting bracket 32 is fixed on the rear plate member 31. A slider 33 is connected with a supporting portion 32a of the mounting bracket 32 by means of a engaging pin member 35 which slidably engages with a cam groove 34a of a cam member 34 fixed on the mounting bracket 32. In contrast with the cam groove 9a of the front cam member 9, the cam groove 34a comprises a rear horizontal groove portion 34b extending substantially in the horizontal direction, and an inclined groove portion 34c downwardly extending to the forward direction from the front end of the horizontal groove portion 34b. The mounting bracket 32 and the slider 33 are provided with guide shoes 36, 37 and 38, 39. A rear drive wire 18 is connected, by means of a guide bracket 40, with the slider 33 which tilts up or opens the rear plate member 31. The rear drive wire 18 is disposed in a housing groove 5d inside the guide rail 5. The rear drive wire 18 engages with a gear 20 which is rotated by a second drive motor 19 located substantially at the center in the rear portion of the frame member 4. Then the rear drive wire 18 extends inside a rear idle cable housing portion 41b, an inner idle cable housing of the cable housing member 41 located below the other guide rail 5. With this arrangement, the rear drive wire 18 is operated by the rotation of the second drive motor 19. Both first and second drive motors 13, 19 are located substantially at the center of the rear portion of the frame member 4. In this way, the first and the second drive motors 13, 19 are disposed in one place so as not to reduce the opening area of the roof panel opening 2a. Furthermore, a portion of reduction gear parts 13a, 19a which are small in the vertical direction are superposed in the upper and the lower directions in one place. In this way, relatively small space (especially the space in the widthwise direction) is required for disposing the first and the second motors 13, 19. The gears 14, 20 are located respectively under the reduction gear part 13a and above the reduction gear part 19a. The drive motors 13, 19 are mounted on the frame member 4 by means of brackets 21, 21.(refer to Fig.6) Stopper members 43, 44 are mounted respectively at the front and the rear ends of the guide rails 5, 5. The interval in the longitudinal direction between the stopper members 43 and 44 is set longer than the length of the flexible member 3 when the flexible member 3 is in the fully-closed state by its tensile force. Accordingly, either the front portion first closes or the rear portion first closes, the flexible member 3 always stretches to the full to close. The stopper member 43, 44 are provided with upwardly-indented stopper grooves 43a, 44a with which the guide shoes 23, 36 engage. For example, if the front portion of the flexible member 3 (the guide shoe 23) first makes contact with the stopper member 43, the front portion tends to be pulled rearwardly when closing the rear portion. However, this force to rearward direction is a tensile force of the flexible member 3 and it acts on the upper direction of the engaging pin member 15. Therefore, the front portion of the flexible member 3 (the front plate member 6) pivotally moves upward with the engaging pin member 15 as a rotational axis. Thus, the guide shoe 23 engages with the stopper groove 43a of the stopper member 43. As a result, the rearward force can be restricted. On the other hand, when opening the front portion of the flexible member 3, force is generated by the drive wire 12. This force acts on the lower direction of the engaging member 15. Therefore, even when the guide shoe 23 engages with the stopper groove 43a of the stopper member 43, the engagement is released. Thus, the front portion of the flexible member 3 withdraws smoothly, opening the roof panel opening 2a. Although not shown in the drawings, a folding mechanism as disclosed in Japanese Utility Model Application Laying Open Gazette No. 63-40228 is mounted between the front plate member 6 and the rear plate member 31 in the flexible member 3. This folding mechanism makes the flexible member 3 foldable. A front portion 4a of the frame member 4 is provided on a front header 51 with a closed cross section. The front header 51 comprises an upper panel 51a and a lower panel 51b. The front portion 4a of the frame member 4 extends rearwardly from the front header 51. The part where the front portion 4a extends from the front header 51 is covered with the front portion of the flexible member 3 (the front plate member 6). Likewise, the rear portion 4b of the frame member 4 is provided on a rear header 52 with a closed cross section. The rear header 52 comprises an upper panel 52a and a lower panel 52b. Reference numerals 53, 54 designate respectively a rear window glass and a front window glass. Side portions 4c, 4c of the frame member 4 are mounted on a roof rail outer 56a of a roof rail 56 with a closed cross section. The roof rail 56 comprises this roof rail outer 56a and a roof rail inner 56b. The roof rails 56, as well as the front header 51 and the rear header 52 enclose the roof panel opening 2a. In the aforementioned embodiment of the present invention, a portion of the reduction gear parts 13a, 19a of the first and the second drive motors 13, 19 are superposed in the upper and the lower positions in one place. However, the position of superposing the reduction gear parts 13a, 19a is not limited to the upper and the lower directions. Furthermore, not only small portions but also the whole portions of the reduction gear parts 13a, 19a can be superposed. As shown in Figs. 8 and 9, the drive motors 61, 62 can be disposed in the upper and the lower positions of the frame member 4 so as to superpose the whole parts of the drive motors 61, 62. In this case, the lower drive motor 62 is covered with a trim 63. Reference numerals 64, 65 designate gears with which the drive wires 66, 66, 67, 67 engage. Reference numeral 68 designates a rear header. In addition, as shown in Figs. 15 and 16, the drive motors 81, 82 having the reduction gear parts 81a, 82a can be mounted apart from each other instead of being superposed. That means the drive motors 81, 82 are disposed in the lower position of the frame member 4 so that the drive motors 81, 82 are spaced apart in the widthwise direction of the vehicle body. In this case, the drive motors 81, 82 are covered with trims (not shown in the drawings). Reference numerals 83, 84 designate gears with which drive wires 12, 12, 18, 18 engage. The following is a description about a control system which controls the above-mentioned drive motors 13, 19 (61, 62). In Fig.10, reference numerals 71, 72 designate a front ON/OFF switch and a rear ON/OFF switch, each provided close to the driver seat for opening or closing the front or the rear portions of the flexible member 3. CPU 73 receives ON/OFF signals from the switches 71, 72 and controls the first and the second drive motors 13, 19 by means of the drive circuits 74, 75. Reference numerals 76, 77 designate respectively a front limit switch and a rear limit switch. These front and the rear limit switches 76, 77 sense the tilt-up state of the front and the rear portions of the flexible member 3 and then input the detection signals to CPU 73. Reference numerals 78, 79 designate lock detecting means for the drive motors 13, 19. The lock detecting means detects the state where the drive motors 13, 19 stop activation thereof when the flexible member 3 opens or closes to the full, or is folded at the central position. (refer to Fig.1) Then the lock detecting means sends the detection signals to CPU 73. Finally, CPU 73, responsive to the signals from the lock detecting means, prohibits the drive circuits 74, 75 from sending the operation signal to the drive motors 13, 19. Control for opening and closing the front portion of the flexible member 3 by the control system is illustrated in Fig.11. For example, when the front ON/OFF switch 71 is in the open position, the first drive motor 13 is activated and tilts up the front portion of the flexible member 3. In detail, the activation of the first drive motor 13 operates the drive wires 12, 12. As a result, the slider 10 slightly withdraws backward, causing the transition of the engaging pin member 15 from the horizontal groove portion 9b to the inclined groove portion 9c of the cam groove 9a of the cam member 9. Since the position of the engaging pin member 15 is restricted in the vertical direction, the front part of the mounting bracket 7 moves upward. In other words, the rear shoe member 22 of the mounting bracket 7 is positioned in the guide groove 5a of the guide rail 5 while the front shoe member 23 is positioned on the upper surface of the guide rail 5. Accordingly, since the mounting bracket 7 is attached on the front plate member 6 by means of the mounting portions 6a, 6b, the front plate member 6 tilts up, thereby creating the clearance between the rear portion of the flexible member 3 and the vehicle roof panel 2. With the end of the tilting-up motion, the front limit switch 76 enters into the ON state. When further setting the front ON/OFF switch 71 in the open position, the drive motor 13 is further activated and the front plate member 6 together with the slider 10 withdraws while folding the front portion of the flexible member 3, thereby opening the front of the roof panel opening 2a. When the flexible member 3 opens to the full, the lock detecting means 78 detects the locking state of the drive motor 13. When turning the front ON/OFF switch 71 in the closed position in this state, the front portion of the flexible member 3 moves forward due to the activation of the drive motor 13. Then, when the flexible member 3 reaches the front end position and the front ON/OFF switch 71 is again turned into the closed position, tilt-up state is released due to the activation of the drive motor 13. The front limit switch 76 becomes OFF state. Finally, the lock detecting means 78 detects the locking state, indicating the end of the opening and closing motion of the front portion of the flexible member 3. As shown in Fig.12, the opening and the closing of the rear portion of the flexible member 3 is controlled by the rear ON/OFF switch 72 in the same manner as the front portion thereof. When activating the second drive motor 19, the rear plate member in the rear of the flexible member 3 moves forward along with the forward movement of the sliders 33, 33. Therefore, the rear portion of the flexible member 3 is tilted up and folded to open the rear of the roof panel opening 2a in the same manner as the front portion of the flexible member 3. Thus, the passengers in the rear seat can enjoy the upper view and can enjoy a comfortable ride. With the activation of the first and the second drive motors 13 or 19, the drive wires 12, 12 or 18, 18 independently operate to moves the right and the left sliders 10, 10, or 17, 17. Consequently, the front or the rear portion of the flexible member 3 can be moved independently of each other. As explained in the preceding description, when the front of the roof panel opening 2a is in the open state, the opening of the rear of the roof panel opening 2a will lead to the circulation of air in the longitudinal direction of the vehicle body and the prevention of the stagnated air in the vehicle cabin with the improved ventilation. Furthermore, the occurance of resonance or throb sound inside the vehicle cabin can be prevented. In the above embodiment, the tilt-up motion of the flexible member 3 is carried out independently of the opening of the front of the roof panel opening 2 by the flexible member 3. However, to enhance the ventilation capacity, it is also possible to operatively interconnect the drive motors 13, 19 so as to control the CPU 63 to tilt up the the rear portion of the flexible member 3 to create at least the clearance between the rear portion of the flexible member 3 and the roof panel in association with the opening of the front portion of the flexible member 3. In this case, the control is illustrated in the time chart of Fig.13. More specifically, when the front ON/OFF switch 71 is in the open position, the first and the second drive motors 13, 19 are driven forward at a fixed rate to tilt up the front and the rear portions of the flexible member 3. On the other hand, when the front ON/OFF switch 71 is in the closed position, the first and the second drive motors 13, 19 are reversed so as to release the tilt-up state of the front and the rear portions of the flexible member 3. In this way, when opening the front portion of the flexible member 3, without any special operation, circulation of air can be improved and passengers on the rear seat can feel comfortable and refreshed, thereby obtaining the excellent ventilation inside the vehicle. As shown in Fig.14, when tilting up the rear portion of the flexible member 3 with the rear ON/OFF switch 72, the operation of the first drive motor 13 or the tilt-up motion can be prevented so as to avoid any inconvenience for passengers on the front seat in case when passengers on the rear seat tilt up the rear portion of the flexible member 3. In this way, the tilt-up motion in the rear seat can be carried out independently of the tilt-up motion of the front seat. In this case, the front limit switch 76 for detecting the tilt-up motion of the front portion of the flexible member 3 is in the OFF state.
