DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof device which is applied to a vehicle, in particular, a vehicle such as a passenger car, and which moves up and down and slides.

[0002]

2. Description of the Related Art As a prior art of this type of sun-roof device, there is one disclosed in Japanese Patent Application Laid-Open No. 2-279422. In this prior art, brackets are provided at the lower left and right sides of a panel that opens and closes an opening of a roof, sliders are provided on guide rails on the left and right sides of the opening, and the slider is positioned with respect to the guide rails during the vertical movement of the panel. An interlocking body that becomes immobile and moves together with the slider during horizontal operation of the panel is provided, and the front and rear of the slider between the bracket and the interlocking body moves the rear part of the panel up and down from the closed position to the lowered position or the raised position. After the operation, an elevating mechanism is provided, and the panel can move horizontally from the lowered position to the open position with the slider and the interlocking member.

The above-mentioned rear elevating mechanism is for tilting the panel about the front part. The rear elevating body has cam grooves formed in the interlocking body and the bracket, respectively, and has a cam pin between the two to engage with each cam groove. The elevating body is moved forward and backward by a slider.

[0004]

In the above prior art, although the thickness of the rear elevating mechanism can be reduced, a long cam groove is required because the rear elevating body is directly engaged with the bracket. , The amount of vertical movement of the rear panel is long, and it is difficult to increase the amount of vertical movement at the rear of the panel and to make the rear vertical mechanism compact. In addition, the rear elevating body engages with the bracket and the interlocking body and is connected to the slider, but only engages with the interlocking body at one point, so the holding force is weak, and the lateral vibration of the panel is prevented. Is difficult to do. In order to prevent this, the rear elevating body may be engaged with the interlocking body at two points via the two cam grooves. However, when the two cam grooves are arranged vertically, the vertical width of the interlocking body is reduced. As a result, the thickness of the apparatus increases, and it becomes difficult to secure the head clearance of the automobile roof.

A first object of the present invention is to provide a lifter between a rear portion of a panel and an interlocking body, and to provide a rear elevating body between the lifter and the interlocking body. The first and second post-elevating means are provided between the first and second panels, respectively, so that a desired amount of rear panel elevating can be obtained with a relatively short post-elevating body movement amount. A second object of the present invention is to form a cam groove for guiding the front part of the rear elevating body up and down and a groove for guiding the front and rear in the interlocking body, and to deepen the rear part of the cam groove for the elevating guide and the front and rear guiding groove. The purpose of the present invention is to make it possible to prevent lateral deflection of the panel and to make the apparatus thinner by performing polymerization while changing the thickness.

The third groove 19 is overlapped with the rear part of the second cam groove 17, and the second cam groove 17 is formed deeper than the third groove 19.

[0008]

When the slider 6 is moved backward from the state in which the panel 3 is in the closed posture A, the rear elevating body 9R moves together with the first elevating body 9R.
The lifter 12 swings downward with respect to the rear elevating body 9R via the rear elevating means 10R, and the swing of the lifter 12 causes the panel 3 to swing.
At the same time, the rear elevating body 9R descends relative to the interlocking body 8 via the second rear elevating means 11R, whereby the rear part of the panel 3 descends greatly . The lifter 1
(2) Since the lever serves as a lever, even if the moving distance of the rear elevating body 9R with respect to the lifter 12 is short, the elevating amount of the rear part of the panel 3 is secured.

The interlocking body 8 has a second cam groove 17 for elevating and lowering the front part of the rear elevating body 9R, and a third groove 19 for guiding the rear part of the rear elevating body 9R back and forth. When the rear elevating body 9R is moved backward, the front part can be lowered to the same height as the rear part, and the rear elevating body 9R is deeper than the groove 19 and the rear part is overlapped at the same height as the third groove 19. When the 9R is moved forward, the front second cam pin 16 is guided to the second cam groove 17 without moving from the groove overlapping position to the third groove 19, and a required elevating operation is performed.
