DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is so constructed that the trailing edge can be selectively moved up and down from a fully closed position which is a continuous surface with respect to the outer surface of a fixed roof, and can be stored in the rear inner surface of the fixed roof. The present invention relates to a sunroof device for a vehicle having a slide panel provided.

[0002]

2. Description of the Related Art A slide panel provided in an opening formed in a part of a fixed roof of an automobile is configured to be able to move back and forth along the inner surface of the fixed roof, and the trailing edge is tilted as required. Sunroofs that can be raised are well known.

In such a type of sunroof, the outer surfaces of the fixed roof and the slide panel are generally formed to be continuous when fully closed. Various technical devices have been devised to enable the slide panel to perform both sliding and tilting operations without causing mutual interference with the outer peripheral edge of the slide panel.

As a mechanism for realizing the above-mentioned operation, for example, a slider driven in a front-rear direction by a push-pull cable is engaged with a guide rail for guiding a slide panel, and a tilt-up component having a vertical component is provided. A cam member provided with two cam grooves for use in lifting and lowering is provided on the slide panel side, a pin protruding from the slider is engaged with the cam groove for lifting down, and one end thereof is pivotally connected to the slider. Japanese Patent Publication No. 55-15325 discloses a structure in which a plurality of pins projecting from the other end of the link are engaged with the cam groove for tilt-up.

[0005]

In the sunroof having the above-mentioned tilt function, there is a problem in the means for defining the tilt-up limit of the slide panel. Generally, it is conceivable that the operating limit is defined by the pin protruding from the link abutting on the end of the tilt-up cam groove. However, according to this, the push-off force of the push-pull cable is always set at the operating limit. Acts on the link, so that parts of the link may be worn for a long period of time, which may cause rattling. It is also conceivable to provide a stopper on the guide rail for defining the movement limit of the slider, but the front rail provided on the front end side of the slide panel also engages with the guide rail, so avoid interference with this. Providing a stopper for the rear slider is extremely difficult.

[0006] The present invention has been devised to solve such disadvantages of the prior art, and its main objects are as follows.
Provided is a sunroof apparatus for a vehicle having an operation limit defining means improved so that an excessive load does not act on a link at an operation limit and interference with other members can be avoided without increasing an installation space. Is to do.

Explanation will be made based on the standard.

As shown in FIGS. 2 and 3, stays 4 extending in the front-rear direction are fixed to both left and right ends of the inner surface of the slide panel 3, respectively. This stay 4
A front slider 5 that engages with a guide rail, which will be described later, is mounted inside the front end of the slider. On the inner surface of the rear part of the stay 4, an obliquely upward cam groove 6a and a substantially horizontal cam groove 6b are continuously formed via a curved groove 6c. 4, a pin 8 projecting outward from a first vertex 7a of a lifting link 7 having a triangular shape is engaged with the cam groove 6, as shown in FIG.

A rear slider 9 is pivotally mounted on both left and right sides of a second vertex 7b of the lifting link 7 so as to be rotatable about an axis extending in the left-right direction. Then, the third vertex 7c has the shape shown in FIG.
As shown in FIG. 1, a roller 10 that rotates around an axis in the left-right direction is mounted as an engaging element. The rear slider 9 and the roller 10 also engage with a guide rail described later.

A pair of guide rails 11 made of a drawn material of an aluminum alloy extend in the front-rear direction at both side edges of the opening 2 on the inner surface of the fixed roof 1. As shown in FIG. 4, the guide rail 11 has a substantially flat base portion 12, a T-shaped portion 13 erected on an inner portion on the upper surface of the base portion 12, and an inward flange on the upper surface. 14, a C-shaped part 15 erected outside the T-shaped part 13 and a groove-shaped part 16 formed adjacent to the outside of the C-shaped part 15. A flat portion 1 continuously provided at an end edge and an upper edge of an outer wall of the channel portion 16;
7 is a stiffener 1 fixed to the inner surface of the fixed roof 1.
8 is fixed.

The T-shaped portion 13 and the groove-shaped portion 16 basically extend over substantially the entire length of the guide rail 11 in the front-rear direction, while the inward flange 14 of the C-shaped portion 15 has
The front side is cut off from a predetermined position. And T-shaped part 1
The sunshade 19 is slid on the inner edge of the T-shaped portion 3.
A front slider 5 and an inner rear slider 9i are slid on the outer edge of 3 and the inward flange 14 is connected to a push-pull cable 20 provided in the C-shaped portion 15 and is driven in the front-rear direction. The outer rear slider 9o and the roller 10 are in sliding contact with each other. The channel 16 functions as a drain.

On both the left and right guide rails 11, drain channels 21 slidably fitted on the inward flanges 14 of the respective guide rails 11 are provided. This drain channel 2
1 has a function of receiving water drops dripping from the rear edge of the opening 2 of the fixed roof 1 and pouring them into the left and right channel portions 16. At a position corresponding to the position of the roller 10 at each of the left and right ends of the drain channel 21, a downwardly concave semicircular engaging member 22 is elastically supported via a leaf spring 23 which is bent up and down. Have been.

Next, further details will be described together with the operation of the present apparatus. In the fully closed state of the slide panel 3 shown in FIG. 3, the rear slider 9o and the roller 10 are both slid on the lower surface of the inward flange 14, and the lifting link 7 is in the upright state. When the tilt-up operation is performed from the fully closed position, the push-pull cable 20 is pushed out, and the rear slider 9 moves forward. Thereby, the lifting link 7 moves forward along the guide rail 11.
Here, the first vertex 7 of the lifting link 7 is inserted into the cam groove 6 of the stay 4.
Since the pin 8a is engaged, as the lifting link 7 moves forward, as shown in FIG. 6, the slide panel 3 flips up its rear edge upward with the front slider 5 as a fulcrum.

The inward flange 1 of the C-shaped portion 15 at a predetermined position in the C-shaped portion 15 and on the base portion 12
The stopper 24 shown in FIG.
Is fixed. The stopper 24 is provided on the C-shaped portion 15.
A first portion 24a that substantially closes the inner hole of the first portion, and a second portion 24b that closes a portion surrounded by the C-shaped portion 15 and the inward flange 14.
The front end of an extension 25a extending forward from a cable holder 25 provided integrally with the outer rear slider 9o is formed by the first portion 2 of the stopper 24.
By colliding with 4a, the movement limit of the front side of the lifting link 7 is defined.

On the other hand, a lock lever 26 is pivotally mounted on the intermediate portion of the stay 4. As shown in FIG. 8, the lock lever 26 has a front end 26a pivotally connected to the stay 4 and a rear end 26b slidingly engaged with the outer edge of the T-shaped portion 13 and the inward flange 14. A stepped portion 26c is provided at a position corresponding to the inward flange 14 at the intermediate portion.

When the slide panel 3 starts a tilt-up operation in accordance with the forward movement of the lifting link 7 as described above, the lock lever 26 moves the front surface 27a of the stepped portion 26c to the second portion 24b of the stopper 24. , The front end 26a is tilted obliquely upward with the rear end 26b as a fulcrum. Here, since the forward movement of the lock lever 26 itself is restricted by the front surface 27a of the stepped portion 26c of the lock lever 26 abutting on the second portion 24b of the stopper 24, the lock lever 26 tilts as the lock lever 26 tilts. Then, the front edge of the slide panel 3 is slightly retracted while performing the tilt-up operation. At the same time, the rear surface 27b of the stepped portion 26c of the lock lever 26 is
4a, and the slide panel 3 is prevented from moving backward in the tilt-up state. In this manner, the front edge of the slide panel 3 retreats somewhat during the tilt-up operation, so that the pressing force acting on the seal member on the front edge side of the slide panel 3 is reduced. The stepped portion 26c
May be formed as a separate member attached to the rear end 26b of the lock lever 26 via a leaf spring without being integrally formed with the lock lever 26.

When the rear slider 9 is driven backward by pulling the push-pull cable 20 from the fully closed position of the slide panel 3, the lifting link 7 moves along the guide rail 11.
Moves backward.

In the portion where the pin 8 of the first vertex 7a of the elevating link 7 in the inward flange 14 is aligned with the roller 10 when the pin 8 reaches the rear end of the cam groove 6, the roller is moved upwardly of the inward flange 14. Notch 2 for moving 10
8 is provided, and a slope 29 for guiding the upward movement of the roller 10 is provided.
The roller 10 that has moved upward of the inward flange 14 with the rearward movement of the roller 10 is held by the engaging member 22. Thereby, as shown in FIG.
At the same time as the state in which the roller 10 is sandwiched between the upper surface of the inward flange 14 and the second slider 2, the rear slider 9 is
The elevating link 7 rotates in the forward tilting direction with the vertex 7b as a fulcrum, and the first vertex 7a moves downward. Accordingly, the stay and the rear edge of the slide panel 3 together with the stay 4 are lifted down.

On the other hand, a hanging piece 30 is integrally formed inside the engaging member 22, as shown in FIG. A stepped groove 31 that can engage with the outer edge of the T-shaped portion 13 is formed on the inner surface of the hanging piece 30. The T-shaped part 13
The stepped portion 3 of the stepped groove 31 is provided at a predetermined position on the outer edge of the horizontal wall.
A notch 32 into which 1a can enter is provided. The engagement between the stepped portion 31 a of the stepped groove 31 and the cutout portion 32 is performed by the roller 10 riding on the inward flange 14 and the engaging member 22.
It is released by pushing up.

Now, in this state, the push-pull cable 2
When the rear slider 9 is driven backward by further retracting the slider 0, the slide panel 3 is retracted inside the fixed roof 1 by engagement of the front and rear sliders 5.9 and corresponding parts of the guide rail 11. At this time, since the vertical movement of the engaging member 22 is regulated by the stepped groove 31 engaging the outer edge of the T-shaped portion 13, the engaging member 22 is sandwiched between the inner surface of the engaging member 22 and the inward flange 14. Since the roller 10 and the engaging member 22 are integrated, the drain channel 21 moves together with the slide panel 3, catches water drops dripping from the trailing edge of the slide panel 3, and discharges the water drops to the left and right channel portions 16.

When the push-pull cable 20 is pushed out from the open state of the slide panel 3, the step 33 formed at the first vertex 7a of the lifting link 7 complementarily engages with the rear end of the stay 4 (see FIG. 11). ). Thereby, the lifting link 7
As a result, the stay 4 is pushed out, and the slide panel 3 moves forward. A holding plate 34 is screwed to the outer surface of the lifting link 7 to prevent the engagement with the stay 4 from being released.

The engaging member 22 moves together with the slide panel 3 to the fully closed position, and the front surface 27a of the stepped portion 26c of the lock lever 26 attached to the intermediate portion of the stay 4 contacts the second portion 24b of the stopper 24. Then, first, the stay 4 stops. When the push-pull cable 20 is further extruded,
The roller 10 moves downward through the notch 32 of the inward flange 14 and enters the lower surface of the inward flange 14. Here, since the engaging member 22 is urged downward by the leaf spring 23, when the roller 10 moves downward, the step 31 a formed on the hanging piece 30 becomes the notch 32 on the outer edge of the T-shaped part 13. And the drain channel 21 stops.
At the same time, the lifting link 7 rises and pushes up the rear end of the slide panel 3 to be in the first fully closed state. The resilient force of the leaf spring 23 maintains the engaging state between the stepped portion 31a of the hanging piece 30 of the engaging portion 22 and the notch 32 on the outer edge of the T-shaped portion 13, so that the drain channel 21 vibrates. And so forth.

[0027]

As described above, according to the present invention, since the movement limit of the rear slider is defined by the stopper directly contacting the end of the push-pull cable connected to the rear slider, the sliding link has a sliding resistance. Since the above load is not applied, the occurrence of wear can be suppressed. Moreover, since the stopper is provided in the cable insertion groove, the stopper can be disposed at a position where mutual interference is avoided without increasing the size of the guide rail itself, thereby increasing the space efficiency in installation. it can.
