Description

TECHNICAL FIELD The present invention relates to a sliding roof device for an automobile.

(Prior Art) In recent years, in an automobile, an opening is formed in the roof from the viewpoint of taking in fresh air outside the vehicle into the vehicle and increasing the feeling of opening the vehicle interior space, thereby providing a comfortable driving feeling. There is a tendency to have so-called sliding roof devices adapted to be opened and closed by a sliding roof that slides along.

By the way, it is desirable that the opening provided in the roof is as wide as possible in terms of enhancing the comfort in the vehicle compartment as described above. From this viewpoint, for example, it is disclosed in Japanese Patent Laid-Open No. 58-161615. As
Openings are formed in the front and rear portions of the roof, and two sliding roofs that are respectively slidable are arranged in these two openings. By selectively opening and closing the two sliding roofs, In addition to selectively opening only the opening or the rear opening, it is known that two openings are simultaneously opened to secure a larger opening area.

However, in this known example, even if the two front and rear sliding roofs are opened at the same time, openings are formed at the front and rear portions of the roof, respectively, so that the total opening area of the openings in the entire roof area is relatively large. Although the amount of fresh air introduced into the chamber is sufficiently secured, since these two apertures are independent of each other, the aperture area of each aperture alone is relatively small, and therefore it is somewhat difficult in terms of openness. There is.

(Object of the Invention) The present invention is intended to solve the problems pointed out in the above-mentioned prior art, and in an automobile in which an opening formed in the roof is opened and closed by a sliding roof, a simple and compact structure is provided. It is an object of the present invention to provide a sliding roof device for an automobile, in which the above-mentioned opening is a single opening and an opening area as large as possible can be obtained to improve the feeling of opening.

(Means for Achieving the Purpose) In the present invention, as means for achieving the above object, an opening formed in a roof of an automobile is opened or closed by a sliding roof that is slidable in a vehicle front-rear direction. In the sliding roof device for an automobile according to the above, the sliding roof is slidable in the front-rear direction of the vehicle body and is arranged at one end side of the opening in the vehicle front-rear direction when the opening is closed. And a second sliding roof which is slidable in the front-rear direction of the vehicle body and is arranged at the other end side of the opening in the vehicle body front-rear direction when the opening is closed, and when the lid is closed, the first sliding roof is provided. Both the sliding roof and the second sliding roof move toward the other end side of the opening, and when the lid is closed, The first sliding roof and the second sliding roof are both configured to move toward the one end side direction of the opening, and the first sliding roof or the second sliding roof is provided at an appropriate position on the first sliding roof or the second sliding roof. An appropriate tilt-up mechanism that acts so as to displace the sliding roof above or below the second sliding roof when moving the sliding roof from the closed state to the open direction; and the first sliding roof. Second
An appropriate connecting mechanism for connecting and sliding the sliding roof of the present invention so as to be engaged and disengaged in a superposed state, an operation cable connected only to the first sliding roof, and a drive means for driving the operation cable. A roof driving device is provided.

(Operation) In the present invention, when the first sliding roof and the second sliding roof are opened from the closed state by the above means, the operation cable is driven by the driving means of the roof driving device. Then, first, the tilt-up mechanism is actuated so that the first sliding roof rides on the second sliding roof or dives under the second sliding roof, and then the first sliding roof is directly moved to the first sliding roof.
After the sliding roof has been moved to the open position, the connecting mechanism is operated to move the first sliding roof and the second sliding roof.
The sliding roofs are interlockingly connected in a superposed state, and are integrally moved in the opening direction to the opening position of the second sliding roof to fully open the roof.

On the other hand, when the roof is closed from the fully opened state, first, the driving means is driven to drive the operation cable, and the first sliding roof and the second sliding roof are left in the overlapping state. The second sliding roof is moved to the closed position, and then the first sliding roof is independently moved to the closed position to fully close the roof.

(Effects of the Invention) Therefore, according to the sliding roof device for a vehicle of the present invention, the first sliding roof and the second sliding roof that close the opening of the roof are vertically overlapped by the tilt-up mechanism and the overlapping is performed. The two sliding roofs are connected by a connecting mechanism so that they can be engaged and disengaged, and by moving the sliding roofs to the outside of the opening as it is, the opening can be fully opened. Further, it is possible to form the first sliding roof and the second sliding roof on substantially the entire area except the space for retracting and holding the first sliding roof and the second sliding roof, and therefore, the conventional sliding roof apparatus. (For example, JP-A-58-1616
As described in Japanese Patent Publication No. 15), a larger single opening can be formed as compared with the case where openings are formed at the front and rear ends of the roof, respectively. Is obtained.

Further, since the first sliding roof and the second sliding roof, which are vertically stacked by the tilt-up mechanism, are interlockingly connected by the connecting mechanism so that they can be engaged and disengaged in the overlapping state, these two sliding roofs are connected. Of the roof, the operation cable is connected only to the first sliding roof to be driven first, and the operating cable is driven by a single driving means, so that the opening portion corresponding to the first sliding roof is opened. It is possible to easily obtain an opening form having two different opening areas in a closed state and a state in which the portion corresponding to the first sliding roof and the portion corresponding to the second sliding roof are both opened. For example, driving means may be provided on both the first sliding roof and the second sliding roof. Only in comparison with the case so as to obtain a different aperture forms these selective use, in which simplification of the cost and the structure of the drive device and can be achieved.

Further, in relation to the first sliding roof 11, the first sliding roof 11 and the second sliding roof 12 are interlocked with each other in association with a pulling operation of the first sliding roof 11 toward the rear of the vehicle body by the roof driving device 26. There is provided a tilt-up mechanism 20 (see FIGS. 3, 9, and 10) that acts so as to be lifted above the position. A coupling mechanism 30 (see FIGS. 4 and 5) for coupling the first sliding roof 11 and the second sliding roof 12 to the rear roof guide 42 so as to be engageable and disengageable in a two-stage overlapping state. (See the figure).

Therefore, when the sliding roof 10 is opened or closed as described above, the first sliding roof 11 and the second sliding roof 12 operate as follows. That is, first, as shown in FIG. 6, in the closed position of the sliding roof 10 (that is, the position where the opening 2 is fully closed), the first sliding roof 11 and the second sliding roof 11 are
The sliding roofs 12 are arranged at substantially the same level and in a butted state in the front-rear direction of the vehicle body. From this state, when a pulling operation force to the rear of the vehicle body is applied to the first sliding roof 11 by the roof driving device 26, the tilt-up mechanism 20 operates and the first sliding roof 11 tilts up. (The change from the state shown in FIG. 9 to the state shown in FIG. 10 or from the state indicated by reference numeral 11 ′ to the state indicated by reference numeral 11 ″ in FIG. 4), the first sliding roof 11 is The first sliding roof 11 and the second sliding roof 12 are integrated into one body by moving the rear side of the vehicle body while riding on the sliding roof 12 and when the second sliding roof 12 is almost overlapped, the connecting mechanism 30 operates. 7 (the state shown in FIG. 7, the state at this time is referred to as a half-open position in the following description). Only Lee loading the roof 11 is opened cover, the opening 2 is in a half-open state (vehicle length direction aperture dimension L _1).

Further, from the state shown in FIG.
When a pulling operation force is further applied by, the first sliding roof 11 and the second sliding roof 12 are integrally moved to the vehicle body rear side while maintaining the overlapping state with each other, and the lid opening position (that is, the opening position). 2 is fully opened) (position shown in FIG. 8). This completes the opening operation of the sliding roof 10. Therefore, in this open state, the opening 2 is fully opened (dimensions in the vehicle length direction).
L _2), resulting in the roof will be forward about two-thirds portion of the at its vehicle length direction are opened.

On the other hand, it is a closing operation from the opening position of the sliding roof 10, but in this case, since the connecting mechanism 30 is in the operating state, the first sliding roof 11 is provided by the pressing operation by the roof driving device 26. Then, the second sliding roof 12 is integrally moved to the front side of the vehicle body in the overlapping state as shown in FIG. 8 to the half open position shown in FIG. When the pressing operation force is further applied by the roof drive device 26, the engagement of the coupling mechanism 30 is released, and the first
The sliding roof 11 and the second sliding roof 12 are movable with respect to each other. Therefore, thereafter, only the first sliding roof 11 receives the pressing operation force of the roof driving device 26 and further moves to the front side of the vehicle body in the tilt-up state, and is positioned at the closed position as shown in FIG. At this time, at the stroke end of the first sliding roof 11 in the closing direction, the front end of the first sliding roof 11 and the opening frame member 3 come into contact with each other, thereby releasing the operation of the tilt-up mechanism 20 as described later. As a result, the first sliding roof 11 is tilted down.

The above is a schematic description of the operation of the sliding roof device Z. Hereinafter, a specific configuration of each component for producing the above-described operation will be described.

The tilt-up action of the first sliding roof 11 is realized by the tilt-up mechanism 20 described below. That is, the tilt-up mechanism 20 includes a slide pin 21 attached to the slider 15 side and an oblique groove-shaped guide into which the slide pin 21 can be fitted, as shown in FIGS. 3, 9, and 10, respectively. The guide plate 22 has a groove 23 and is attached to the first sliding roof 11 side. According to the tilt-up mechanism 20, the pulling operation force (the operation force in the direction of moving the slider 15 to the rear side of the vehicle body) by the roof drive device 26 is not acting on the slider 15, or the slider 15 When a pressing operation force (an operation force in the direction of moving the slider 15 to the front side of the vehicle body) is applied to the slide pin 21 on the slider 15 side, the slide pin 21 on the slider 15 side is located at the upper end of the guide groove 23 as shown in FIG. Since it is located in the portion 23a, the guide plate 22
(That is, the first sliding roof 11) is positioned at the lowered position (closed position), but when a pulling operation force is applied to the slider 15, the slide pin 21 moves as shown in FIG. Since it is located at the lower end 23b of the guide groove 23, the guide plate 22 is lifted up by the dimension h. That is, the first sliding roof 11
The tilt up of is realized.

In addition, in the tilt-up state of the first sliding roof 11, reference numeral 11 (indicated by diagonal lines) in FIG.
The first sliding roof 11 is positioned above the second sliding roof 12 as shown in FIG.

As shown in FIGS. 2 and 4, the second sliding roof 12 has a flat plate portion 12a at its outer peripheral edge, and a closed cross-section portion 12b is formed at a position 12b immediately inward of the flat plate portion 12a.
The second sliding roof 12 has a flat plate portion 12a.
While the rear roof guide 42 of the first roof guide 4 is fixedly arranged on the upper surface side of the above, a slider 16 is attached to the lower surface side of the flat plate portion 12a via a bracket 17. The slider 16 is slidably supported by a second roof guide 5 fixed to the roof 1 side and having a substantially sectional shape. Therefore, the second sliding roof 12 is guided by the second roof guide 5 and is slidable in the longitudinal direction of the vehicle body. In the second sliding roof 12, the tip of the flat plate portion 12a is used as the outer sealing material 44 provided on the opening frame member 3 side, and the closed cross-section portion 12b is used as the opening 2 of the roof 1. The inner sealing members 45 provided at the edges are brought into contact with each other in an airtight and watertight manner.

Further, a connecting mechanism 30 is provided near the rear end of the rear roof guide 42 on the vehicle body side. This connecting mechanism 30
As described above, the first sliding roof 11 and the second sliding roof 12 are for interlockingly and interlockingly connected in a substantially overlapping state, and in this embodiment, the slider 15 is slidably moved appropriately. This is achieved by regulation, and its concrete structure is as follows. That is, as shown in FIGS. 4 and 5, the coupling mechanism 30 includes an end stopper 35 provided at the rear end 42a of the rear roof guide 42, and a slider 15 sliding from the end stopper 35. The cam lever 31 is disposed at a position separated by a dimension substantially corresponding to the length in the moving direction. The cam lever 31 is pivotally mounted in the direction of arrow 1-m by a pivot pin 33 so that the cam-shaped protruding end 31a can be appropriately protruded into the rear roof guide 42, and the spring is attached. It is always urged in the direction of arrow l by the spring force of 32. Therefore, when the slider 15 is positioned between the end stopper 35 and the cam lever 31 as shown in FIG. 5 (states of FIGS. 7 and 8), the slider 15 is positioned in front of and behind it. The movement is restricted by the end stopper 35 and the cam lever 31, and the first sliding roof 11 and the second sliding roof 12 are integrally connected. When an operating force in the direction of arrow n is applied to the slider 15 from this state, the slider 15 is held in this state as long as the operating force is smaller than the urging force of the cam lever 31 by the spring 32, The first sliding roof 11 and the second sliding roof 12 are moved integrally in the direction of arrow n (front side of the vehicle body) (the state in the middle of shifting from FIG. 8 to FIG. 7).

On the other hand, when the movement of the second sliding roof 12 to the front side of the vehicle body is restricted (that is, the slider 16 engages with the stopper 48 provided on the second roof guide 5 as shown in FIG. 7). In this state, the pressing operation force becomes larger than the urging force of the cam lever 31 by the spring 32, and therefore the slider 15 is forced to rotate the cam lever 31 in the direction of arrow m to move to the front side of the vehicle body. (At the time of transition from FIG. 7 to FIG. 6). As described above, according to the coupling mechanism 30, the first force is determined based on the magnitude relationship between the operation force of the roof drive device 26 and the spring force of the spring 32.
The sliding roof 11 and the second sliding roof 12 act so as to be interlockingly connected to each other in a freely detachable manner.

The roof driving device 26 slides the first sliding roof 11 of the sliding roof 10 as described above, thereby interlocking the first sliding roof 11 and the second sliding roof 12 with each other. Is operated so as to appropriately open or close the lid, and as shown in FIG. 11, a drive motor assembly 27 and a pair of left and right operation cables 28A and 28B which are operated to move back and forth by the drive motor assembly 27. Have The sliders 15, 15 ... Fixed to the first sliding roof 11 are connected to the tip ends of the operation cables 28A, 28B, respectively. In this embodiment, the operation cables 28A and 28B are attached to the sliders 15 and 15, respectively. However, in other embodiments, as shown in FIG. 9 and FIG. In a direction opposite to that of the above embodiment as shown by a chain line (reference numeral 23 '), and with the slide pin 21 of the slider 15 engaged in the guide groove 23', the operating cables 28A, 28
Instead of the slider 15, the tip of B may be directly attached to the first sliding roof 11.

As described above, in the sliding roof device of this embodiment, the two sliding roofs 11 and 12 for opening and closing the opening 2 are vertically stacked by the tilt-up mechanism 20, and the coupling mechanism 30 is engaged and disengaged in this stacked state. By freely interlockingly connecting, the operation cable is connected only to the first sliding roof 11 of the above two sliding roofs 11 and 12, and this is driven by a single driving means to have different opening areas.
