Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sunroof opening/closing mechanism for an automobile equipped with a tilting sunroof capable of closing a roof opening of a vehicle body.

(Prior Art) A car with a sunroof structure in which the roof of the car body is opened improves lighting and ventilation in the car interior, and can give a feeling of refreshing space and openness.
The one disclosed in the publication No. 1 is known.

As shown in Fig. 9, this conventional example includes a tilt-type sunroof b that can close a roof opening a of the vehicle body, and a sunroof that can slide along a guide rail C provided on the side edge of the roof opening a. a slider d disposed in the sunroof b; and a lift stay f supported at its base end so as to be rotatable up and down by a pivot pin e, and a distal end portion of the lift stay f engages with a mounting bracket g of the sunroof b. When the sunroof b is connected via the pin h and the sunroof b is in the closed state, the lift stay f rises and rotates in response to the slider d connected to the tip of the push-pull wire i retreating (toward the right in the figure). However, when the sunroof b is in the open state, the lift stay f is rotated to fall as the slider d moves forward (to the left in the figure) (problem to be solved by the invention).By the way, when such a sunroof is in the closed state When in
The lift stay and the sunroof are approximately parallel to each other, and there is a drawback in that the sunroof tends to float up when an external force in the tilt-up direction is applied to the engagement pin. On the other hand, in the above conventional example, the up-and-down rotation of the lift stay is restricted at the base end, but the base end responds to the rotational moment acting on the distal end of the lift stay. There is a problem in that it is difficult to prevent the lift stay from rotating, and it is insufficient to prevent the sunroof from floating or rattling.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a sunroof opening/closing mechanism for an automobile that can reliably prevent a sunroof in a closed state from lifting up or rattling.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the invention of claim 1 includes a rotation regulating pin that protrudes laterally at the tip of the lift stay, and a rotation control pin that projects sideways when the sunroof is in a closed state. A claim characterized in that a guide portion is provided that restricts the upward movement of the rotation regulating pin while the slider is slightly retreating, and guides the upward movement of the rotation regulating pin as the slider retreats further. The invention of item 2 is the above-mentioned invention, in which the mounting bracket is provided with a long hole through which an engagement pin connecting the mounting bracket and the distal end portion of the lift stay is inserted and guided in the front-rear direction,
An arc-shaped guide part is provided at the rear of the mounting bracket, centered at the rear end of the elongated hole, and at the tip of the lift stay, the lift stay is located at the rear end of the elongated hole. A rotation restriction pin is provided that slides into contact with the guide portion when the slider rotates up and down, and when the slider retreats, the upward movement of the rotation restriction pin is restrained until the engagement pin reaches the rear end of the elongated hole. The present invention is characterized in that a restraining portion is provided that allows the rotation regulating pin to move upward when the dowel pin is located at the rear end portion.

(Function) According to the invention of claim 1, the rotation regulating pin protrudes laterally from the undulating rotation surface of the lift stay, and when the lift stay is in the laid down state, the rotation regulating pin is located at the tip of the lift stay. Since the upward movement of the rotation regulating pin is restrained by the guide portion, when the sunroof is in the closed state, the upright rotation of the lift stay can be prevented at the tip portion.

Thereby, it is possible to reliably prevent the sunroof in the closed state from floating or shaking due to an external force in the tilt-up direction acting on the engagement pin. After the slider has moved back a little, the guide section guides the slider upwardly, so that the lift stay can rise up and rotate accordingly, thereby tilting up the sunroof.

According to the invention of claim 2, in addition to the above operations, the following operations are performed.

When the slider retreats with the sunroof in the closed state, the engagement pin is guided from the front end to the rear end by the elongated hole of the mounting bracket. The rotation regulating pin is restrained from being driven by the restraining portion until the engagement pin reaches the rear end, but once the engagement pin reaches the rear end, the rotation restriction pin is allowed to be driven. - On the other hand, since the engagement pin is prevented from retreating by the elongated hole, the lift stay is rotated upright by a rearward force acting on the base end around the engagement pin. When the lift stay rotates up and down, the rotation regulating pin comes into sliding contact with the guide portion of the mounting bracket, thereby regulating the position of the engagement pin in the elongated hole of the mounting bracket at the rear end of the elongated hole. Therefore, when the sunroof is tilted up or tilted 1-down, the rotation restriction pin can be accurately positioned with respect to the restriction portion, and the rotation restriction pin can smoothly pass between the restriction portion and the outside. Thereby, the sunroof can be tilted up and down smoothly.

When the movable slider 12 moves backward in this state, only the rear slider 11 slides backward because the switching pin 30 of the auxiliary plate 27b of the rear lid 4 is still located within the guide member 32 and the forward and backward movement is restricted. Accordingly, the engaging pins 28a, 28b move backward along the elongated holes 29a, 29b, and pull down the brackets 26a, 26b, respectively, as shown in FIGS. 3(a) and 3(b). The switching pin 30 moves down along the guide member 32. Thereby, the rear lid 4 can be lowered as shown by the solid line in FIG. At this time, the rear long hole 2
Since the vertical dimension of the lid 9b is larger than that of the front long hole 29a, the amount of descent of the rear lid 4 on the rear side is larger than on the front side, which is advantageous in avoiding interference with the roof part 1 when sliding rearward.

When each engagement pin 28a, 28b reaches the rear end of the elongated hole 29a, 29b, the switching pin 30 passes through the notch recess 31 of the rear guide rail 9b and enters the groove 90.
By moving the movable slider 12 rearward in this state, the rear lid 4, which is in the lowered state, can be slid rearward. When the movable slider 12 reaches the retracted position, the roof opening 2 can be fully opened as shown by the imaginary line in FIG.

When closing the roof opening 2, the movable slider 12 is moved forward. Along with this, the rear slider 11 moves forward. At this time, the second engagement portion 38b of the 20th lever 34b of the front rear slider lla slides into contact with the bottom wall of the rear rail 9b, and the movable slider 12 of the second fitting portion 36b
Since the disengagement from the second engagement recess 33b is restricted, the engagement between the movable slider 12 and the slide mechanism B is reliably maintained. Further, since the upward movement of the switching pin 30 is restricted by the folded upper edge 9e of the rear guide rail 9b, it is possible to prevent the rear lid 4 from floating up and interfering with the roof portion 1 while the rear slider 11 is moving forward. can.
