Abstract

PURPOSE:To improve appearance while to achieve sufficient vent by pulling the rear portion of finisher plate to movable lid side thereby narrowing the gap between both members upon tilting of movable lid at the opening of roof. CONSTITUTION:Upon tilting of a movable lid 3, a pivot shaft 26 will follow to the tilting motion to describe an arched locus while a guide pin 27 will slide in a slit 28 until contacting with the end and a coupling arm 24 will rise by the angle theta. Consequently the rear section of the finisher 8 is pulled to the movable lid 3 by the height (e). Since the relative distance d' between the movable lid 3 and the finisher plate 8 will approach by the dimension (e) when compared with the distance (d) under closing, the gap 16 is narrowed to blind the parts assembled in the plate 8 while to widen the ventilation opening 17 to provide sufficient ventilation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding roof structure for a vehicle, and more particularly to an improvement in a sliding roof structure for a vehicle that is provided with a movable lid that can be tilted.

Conventional sliding roof structures for vehicles of this type include, for example:
As shown in FIG. 1, a movable lid 3 is fitted into a roof opening 2 formed in a roof panel 1, and a frame 4 is disposed on the back side of the roof panel 1.
A lid storage part 5 is formed between the frame 4 and the frame 4. On the left and right sides of the frame 4, there are guide rails 6 extending in the longitudinal direction of the vehicle body.
is laid down and shown on this guide rail 6, and this movable lid 3 is tilted to ventilate the vehicle interior, while the movable lid 3 is slid toward the rear of the vehicle body and stored in the lid storage section 5. There is something I did.

In this type, a finisher plate 8 is generally provided on the back surface of the movable lid 3, as shown in FIGS. 1 and 2, for closing the lower part of the indoor side of the frame 4. 8 is configured such that its front portion is supported by a clip on the front lid reinforcement 3a of the movable lid 3, so that it follows the movable lid 3 and operates. That is, the lifting device 10 has the movable lid 3
A lifting bottle 11 is provided protruding downward from the rear ayu force 3b, and at the tip of the lifting bottle 11 there is a lifting roller 12 that is movable in the longitudinal direction of the lifting bottle 11 and has a locking flange 12a at the lower end. The lifting roller 1 is provided at the rear of the finisher plate 8.
A bracket 13 is provided to hold the lifting roller 12 while allowing a predetermined movement stroke of 2, and a seat plate 14 arranged on the upper surface of the bracket 13 and a rear reinforcement 3b are spaced apart from each other. A spring 15 is interposed therebetween to bias it in the direction in which it moves. At this time, when the movable lid 3 is closed, the locking flange 12a of the lifting roller 12 is attached to the bracket 13.
It is placed in contact with or close to the earthen wall.

For this reason, when the movable lid 3 is tilted, as shown in Fig. 3 (a)
), the lifting roller 12 moves upward together with the movable lid 3 from the position shown by the two-dot chain line to the position shown by the solid line. Make sure to contact the
The rear part of the finisher plate 8 is forcibly lifted upward by the movement stroke of the lifting row 212.

Furthermore, when the movable lid 3 is sliding, it is necessary to sink the movable lid 3 from the closed position indicated by the two-dot chain line to the position indicated by the solid line, as shown in FIG. 3(b). Since the movable lid 3 can move downward until it comes into contact with the lower wall of the bracket 13, a sufficient amount of depression of the movable lid 3 can be ensured. In addition, in Figures 2 and 3,
18 is a weather strip for sealing the periphery of the movable lid 3; 19 is a seal rubber provided on the periphery of the frame 4 and comes into elastic contact with the back surface of the roof panel 1; and 20 is a welt on the lower edge of the indoor side.

However, in such a conventional sliding roof structure for a vehicle, the rear part of the finisher plate 8 is not forcibly lifted up by the lifting device 10 when the movable lid 3 is tilted. However, due to the configuration of the lifting device 10, the relative position between the movable lid 3 and the rear part of the finisher plate 8 when the movable lid 3 is tilted is approximately the same as the relative position between the two when the movable lid 3 is closed. ing. For this reason, the movable lid 3
During the tilt operation, a gap 16 approximately equal to the thickness of the frame 4 is formed between the movable lid 3 and the rear part of the finisher plate 8.
The various parts incorporated into the finisher plate 8 are visible from the outside through the holes, which significantly impairs the quality of the appearance. The area of the ventilation gap 17 formed between the rear part of the plate 8 and the roof opening 2 becomes narrow, and there is a risk that the vehicle interior will not be sufficiently ventilated.

The present invention has been made based on the above-mentioned viewpoints, and an object of the present invention is to be able to pull the rear part of the finisher plate toward the movable lid during the movable lid tilt operation, and thereby to separate the rear part of the finisher plate and the movable lid. To provide a sliding roof structure for a vehicle, which improves the appearance quality by narrowing the gap between 1 and 1, and widens the ventilation opening area to sufficiently ventilate the interior of the vehicle.

The gist of the present invention is to pivotally support one end of a connecting arm extending in the front direction of the vehicle body on the rear rear surface of the movable lid, and to attach a member other than the connecting arm to a member that moves together with the movable lid when the movable lid slides. The ends of the connecting arm are connected so as to be relatively movable in the front and back direction, and the connecting arm is actuated to stand up when the movable lid is tilted.One end of the support arm is of course pivotally supported at the rear of the back surface of the movable lid, and the other end of the support arm is A vehicle slide that supports the rear part of the finisher plate at the end, and rotates the support arm following the rising movement of the connecting arm when the movable lid is tilted, thereby drawing the rear part of the finisher plate toward the movable lid. It has a movable roof structure.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the embodiment shown in FIGS. 4 to 6, the movable lid 3
is a pair of front and rear shoes 21f on the guide rail 6,
21r is slidably attached, and the front shoe 21f as a driving shoe and the front mounting bracket of the movable lid 3)
22f for relative movement, and the front and rear shoes 21f, 21r and the rear mounting bracket 2r of the movable lid 3 are connected via a link mechanism consisting of a pair of link pieces 23a, 23b. When the front shoe 21f is slid from the closed position of the movable lid 3 toward the front of the vehicle body, the link mechanism is actuated to raise the movable lid 3, and the front shoe 21f is moved forward. When the movable lid 3 is slid toward the rear of the vehicle body from the closed position, the link mechanism collapses and the movable lid 3 sinks, so that the movable lid 3 is stored in the lid storage section 5 in this state. It has become.

In this embodiment, as shown in FIGS. 4 and 5, the rear part of the Hj'#J lid 3 is connected to the rear shoe 2:Jr via a pair of connecting arms 24 extending in the longitudinal direction of the vehicle body on both sides thereof. connected. One end of this connecting arm 24 is attached to a flat reinforcement 25 on the back side of the rear mounting bracket 22r, and a pivot 26 is attached to a mounting piece 25a formed by cutting a part of this reinforcement 25 downward.
is supported by. On the other hand, a guide bin 2γ is provided at the other end of the connecting arm 24 to protrude toward the vehicle width direction, and a rear shoe 27. A long hole-shaped guide slit 28 is formed in the inner wall of the r and extends in the longitudinal direction of the vehicle body, and the guide bin 2γ is slidably engaged in the guide slit 28. As shown in FIG. 6(a), the connecting arm 24 is arranged so as to face diagonally forward and downward when the movable lid 3 is closed, and is operated to raise the movable lid 3 when the movable lid 3 is rotated. It is supposed to be done.

Further, the finisher plate 8 is a flat member having a cover 7 flange 8a rising from the rear part of the solenoid to the left and right rear parts, and the front part of the finisher plate 8 is connected to the front lid rain of the movable lid 3, as in the conventional case. Although it is clipped to a force (not shown), the rear part of the finisher plate 8 is supported by a pair of support arms 429 provided on the rear lid reinforcement 3b, which is different from the conventional one. As shown in FIGS. 4 and 5, one end of this support arm 29 is coaxially supported with the pivot 26 of the connecting arm 24, and the other end of this support arm 29, that is, the free rotation end. The support arm 29. An engaging sling 30 is provided which extends along the longitudinal direction of the holder and is open at the tip. On the other hand, a bin mounting bracket 31 is attached to both sides of the rear part of the finisher plate 8 by rivets 32 or the like. is installed protrudingly. The retaining pin 33 is slidably engaged in the engaging slit 3o, and when the movable lid 3 is closed, the leading end of the engaging slit 30 is closed as shown in FIG. 6(a). It is located in Shi.

Further, a stopper portion 34 is formed by cutting out a part of the support arm 29 at the pivot 26 of the support arm 29, and a stopper portion 34 is formed at the pivot 26 of the connection arm 24. A stopper wall 35 offset in the direction is formed, and the stopper portion 34 comes into contact with the stopper wall 35 to regulate the relative position of the support arm 29 and the connecting arm 24, and is movable. When the lid 3 is closed, the support arm 29 is arranged to extend diagonally rearward and downward toward the finisher plate 8 side, as shown in FIG. 6(a).

Furthermore, on both sides of the front side of the finisher plate 8,
As shown in FIG. 4, support pins 37 are provided to protrude outward through the L-shaped bracket, and these support pins 31 and the engagement pins 33 are connected to the guide rail 6. The finisher plate 8 is slidably fitted into a guide channel part 38 provided on the inside, so that when the movable lid 3 slides, the finisher plate 8 slides along the guide channel part 3B without wobbling. A notch 39 is formed in the soil wall of the guide channel section 38 corresponding to the position of the locking pin 33 when the movable lid 3 is closed, and the engaging pin 33 is located at the position of the locking pin 33 when the movable lid 3 is tilted. The finisher plate 8 is separated from the guide channel portion 38 through the cutout portion 39 and is made to follow the movable lid 3.

Therefore, according to the sliding roof structure for a vehicle according to this embodiment, when the movable lid 3 is closed, the finisher plate 8 closes the lower part of the indoor side of the frame 4, as shown in FIG. 6(a). The relative distance between the movable lid 3 and the rear part of the finisher plate 8 is determined by the thickness dimension of the frame 4 (cII
It corresponds to

Further, when the movable lid 3 is tilted, as shown in FIG. 6(b), the pivot 26 at one end of the connecting arm 24 moves from the position shown by the imaginary line to the solid line, following the tilting movement of the movable lid 3. The guide bin 2T at the other end of the connecting arm 24 must be moved to the position while drawing a circular trajectory.
slides rearward in the guide slit 28 of the rear shoe 21r until it abuts the end, and the movable lid 3
Compared to the closed state, the connecting arm 24 moves counterclockwise by an angle θ. In this state, the stopper portion 34 of the support arm 29 is in contact with the stopper wall 35 of the connection arm 24, so the support arm 29 follows the rising movement of the connection arm 24 and rotates the pivot 26. It rotates counterclockwise around the center, that is, upwardly by the angle θ. At this time, the retaining pin 33 engaged in the engagement ring 30 of the support arm 29 follows the movable lid 3 and rises by the amount that the support arm 29 rises. Compared to the case when the movable lid 3 is closed, the rear part of the finisher plate 8 is moved upward by the rotation of the engagement pin 33 as the support arm 29 is rotated. When the movable lid 3 is tilted, the relative distance between the movable lid 3 and the rear part of the finisher plate 8 (d is the height dimension when the movable lid 3 is closed). Therefore, the gap 16 between the movable lid 3 and the rear part of the finisher plate 8 is narrower than before, and the gap 16 between the movable lid 3 and the rear part of the finisher plate 8 is narrower than before. In addition, since the rear part of the finisher plate 8 is drawn toward the movable lid 3, the area of the ventilation space 17 is wider than before.
The vehicle interior is sufficiently ventilated.

Furthermore, when the movable lid 3 is stored, the rear part of the movable lid 3 sinks downward from the position shown by the imaginary line to the position shown by the solid line, as shown in FIG. 6(c). At this time, the connecting arm 24 pivotally supported on the movable lid 3 side
Since the other end of the support arm 29 can move relative to the rear shoe 21r and the finisher plate 8, respectively, the connecting arm 24 and the support arm 29 can rotate in the direction of expanding each other. Therefore, when both arms 24 and 29 rotate in the direction of expanding each other, the stopper portion 34 of the support arm 29 does not come into contact with the stopper wall 35 of the connecting arm 24.

Therefore, the connection arm 24 and the support arm 29 are
The movable lids 3 slide toward the rear of the vehicle body in a sunken state and are stored in the lid storage portion 5 without collapsing in the direction of mutual expansion following the amount of rearward sunkening of the movable lids 3.

In the above embodiment, the connecting arm 24 and the rear shoe 21r are engaged with the guide pin 2γ and the guide slit 28, but the invention is not limited to this, and the guide pin 21 and the guide The arrangement of the slits 28 may be reversed, and in short, it is sufficient that the connecting arm 24 and the rear shoe 21r are connected so as to be relatively movable. Further, since the connecting arm 24 may be one that operates to raise when the movable lid 3 is tilted, for example, one link piece 23a of the link mechanism that supports the movable lid 3
It may also be used as the k-connection arm 24.

Further, the connecting arm 24 and the support arm 29 are connected to the pivot 2
6, they are coaxially supported, but they do not necessarily have to be coaxially supported. Furthermore, the design of the stopper structure for regulating the relative position of the connecting arm 24 and the support arm 29, the support structure of the support arm 29 at the rear of the finisher plate 8, etc. may be changed as appropriate.

As described above, according to the sliding roof structure for a vehicle according to the present invention, one end of the connecting arm extending in the longitudinal direction of the vehicle body is pivotally supported at the rear of the back surface of the movable lid, and the movable roof structure is movable when the movable lid slides. The other end of the connecting arm is relatively movably connected to a member that moves together with the lid, and the connecting arm is operated to raise when the movable lid is tilted;
One end of a support arm is pivotally supported at the rear of the rear surface of the movable lid, and the other end of the support arm supports the rear part of the finisher plate, and the support arm rotates by following the rising operation of the connecting arm when the movable lid is tilted. Since the rear part of the finisher plate is moved closer to the movable lid side when the movable lid is tilted, the rear part of the finisher plate does not come closer to the movable lid side than when the movable lid is closed. , it is possible to narrow the gap between the rear part of the finisher plate and the movable lid, making it difficult to see various parts inside the finisher plate from the outside, and improving the appearance quality when the movable lid tilts at 6 o'clock. Since the ventilation opening between the rear part of the finisher plate and the roof opening is wide, the vehicle interior can be sufficiently ventilated.
