DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding roof device (also referred to as a sunroof device) which is used by being attached to a roof of a vehicle.

[0002]

2. Description of the Related Art As one of such sliding roof devices, a guide rail is provided along both sides of an opening formed in a roof panel of a vehicle along a front-rear direction.
A shoe member connected to a driving force transmitting member driven and driven by a driving mechanism guided by being slidably mounted in the front and rear direction on the guide rail, and the opening portion connected to the shoe member via a link bracket; A movable panel that can be opened and closed, and the link bracket is operated by a sliding operation of the shoe member to make the movable panel flush with the roof panel and close the opening. In addition, there is an apparatus which moves to an open position where the opening is opened below the roof panel, and is disclosed in, for example, JP-A-7-81426.

[0003]

By the way, in the sliding roof device disclosed in the above-mentioned publication, a link bracket has a bracket body for supporting the movable panel from below, and is integrally assembled to the bracket body. A guide block, and a link connected to the guide block via a first guide pin, connected to the bracket body via a second guide pin, and connected to a driver (shoe member) via the connection pin.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a guide rail provided along both sides of an opening formed in a roof panel of a vehicle along a front-rear direction. A shoe member connected to a driving force transmitting member driven and driven by a driving mechanism guided by being slidably mounted in the front and rear direction on the guide rail, and the opening portion connected to the shoe member via a link bracket; A movable panel that can be opened and closed, and the link bracket is operated by a sliding operation of the shoe member to make the movable panel flush with the roof panel and close the opening. And a sliding roof device which is moved to an open position where the opening is opened below the roof panel. A guide shoe formed and assembled to the guide rail so as to be slidable in the front-rear direction and tiltable in the up-down direction, and a guide protrusion defined by engagement with a guide block provided on the guide rail; A resin molded product integrally comprising a cam groove provided on the shoe member for engaging with a cam follower, and a connecting support for supporting the movable panel from below.
Of the present invention).

In this case, when the movable panel is at the fully closed position, the movable panel is detached from the guide rail at the rear portion of the link bracket, and is fitted to the guide rail when the movable panel is at the open position. When the movable panel moves between the open position and the retracted position behind the movable panel, an engagement protrusion that is guided by being restricted in the vertical movement by the guide rail can be formed (the invention according to claim 2). It is.

[0006]

In the sliding roof device according to the present invention (the invention according to claim 1), the link bracket has a structure integrally including the front shoe portion, the guide projection portion, the cam groove portion, and the connection support portion. In addition, the number of components can be reduced, and the number of connecting portions of the components, which may cause play, can be reduced and the elastic body can be eliminated, thereby reducing the cost. Also, since the link bracket is made of a resin molded product,
It is possible to reduce the required weight of the vehicle.

Further, in the sliding roof device according to the present invention (the invention according to claim 2), when the movable panel moves between the open position and the retracted position behind the movable panel, the vertical movement is restricted by the guide rail. Since the guided projection is formed at the rear part of the link bracket, when the movable panel moves between the open position and the storage position, the engagement projection of the link bracket restricts the vertical movement by the guide rail. Thus, the floating of the movable panel is prevented.

As shown in FIG. 16, when the slide panel 18 is tilted from the fully closed position to the tilt-up position, and the shoe member 23 is moved rearward by the flat tooth rack belt 25, as shown in FIG. The slide panel 18 is tilted from the fully closed position to the open position.

The support hole 21f is provided in each of FIGS.
As shown in FIG. 1, it has a function of supporting the gutter member 42 in a tiltable manner. As shown in FIGS. 4 and 11, the engagement protrusion 21g is formed at a rear portion of the link bracket, and separates from the guide rail 14 when the slide panel 18 is at the fully closed position. Is in the open position, it fits into the guide rail 14 through the notch 14a, and when the slide panel 18 moves between the open position and the storage position behind it (the shoe member 23 moves rearward in the state shown in FIG. 15). When moving or returning), the guide rail 14 restricts the movement in the vertical direction and is guided.

As shown in FIGS. 3, 4 and 12, the rear connection supporting portion 21h is connected to an arm 18b2 provided at the lower rear portion of the slide panel 18 via a screw 54 (a nut is inserted). Molded portion) and has a function of supporting the slide panel 18 from below, like the front connection support portion 21c. In addition,
The arm 18b2 is formed integrally with the bracket 18b.

In the embodiment constructed as described above, the link bracket 21 (22) is connected to the front shoe portion 21a, the pushing portion 21b, the front connection support portion 21c,
Guide projection 21d, cam groove 21e, support hole 21
f, since the engaging projection 21g and the rear connection supporting portion 21h are integrally provided, the number of components can be reduced, and the number of connecting portions of the components that cause play may be reduced to reduce the elasticity. The body can be abolished, and the cost can be reduced. In addition, since the link bracket 21 (22) is made of a resin molded product, it is possible to reduce the weight required for the vehicle.

In this embodiment, when the slide panel 18 moves between the open position (the position shown in FIG. 15) and the storage position behind the slide panel 18, the vertical movement is regulated by the guide rails 14 and guided. Since the engagement projection 21g is formed at the rear part of the link bracket 21, when the slide panel 18 moves between the open position and the storage position, the engagement projection 21g of the link bracket 21 is formed.
Is restricted by the guide rails 14 in the vertical direction, so that the slide panel 18 is prevented from floating.

In the above embodiment, as shown in FIG. 6, the slide panel 18 is provided with a glass plate 1 having a predetermined shape.
8a, a bracket 18b adhered and fixed to the lower surface on both left and right sides of the glass plate 18a, a resin molding 18c fixed to the periphery of the glass plate 18a, and a weather strip 18d fitted and fixed around the resin molding 18c. As shown in FIGS. 17, 18 and 19, the slide panel 118 is
a and a weather strip 118d integrally formed on the periphery of the glass plate 118a.

In this embodiment, the weather strip 11 is not affected by the outer shape accuracy of the glass plate 118a.
The outer shape accuracy of 8d (the outer shape accuracy of the slide panel 118) can be ensured. Also, the weather strip 11
Since 8d has a hollow cross section at regular intervals, it is possible to ensure sealing performance and suppress deformation due to sliding with the opening 13 due to tilting in the vertical direction. The weatherstrip 118d may have a solid surface and a sponge on the inside, and the rigidity may be appropriately set, or the surface may be subjected to embossing (irregularity processing) or the like to improve slidability. is there.
