Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This field is related to automobile sunroof structures.

[0002]

2. Description of the Related Art Conventional sunroof structures for automobiles include, for example, those shown on page D-52 of "New Model Car Manual (N14-1)" issued by Nissan Motor Co., Ltd. in August 1990, and FIGS. There is something like that shown in 3 (Actual Kaihei 3
-108555 gazette).

A roof opening 2 formed in a roof 1 of an automobile is provided with an opening / closing lid 3 and a sunshade 4 which are slidable back and forth. A frame 5 is provided on the periphery of the roof opening 2, and the opening / closing lid 3 for forming the drip groove D is formed on both left and right sides of the frame 5.
The rail portion 7 for supporting the driving wire 6 is integrally formed.

A guide rib 8 is provided on the inner side surface 7a of the rail portion 7 so as to project in the front-rear direction. The left and right ends of the sunshade 4 are provided with U-shaped end engaging portions 9 which are engaged with the guide ribs 8 to support the sunshade 4 so as to be slidable back and forth. is doing.

Further, below the frame 5, there is provided a head lining 11 attached to the side roof rail 10 and the like by screw means (not shown). The head lining 11 is composed of a core material 12 and a urethane soft skin portion 13 that covers the lower surface of the core material 12,
An opening 11a is provided at a position corresponding to the roof opening 2. The soft skin 13 also covers the inner end 12a rising above the opening 11a. Then, in particular, a portion near the inner end 12a of the headlining 11 is attached to the lower surface of the frame 5 via a surface fastener M known as a magic fastener (trade name) or the like. In the headlining 11 thus mounted, the soft skin portion 13 at the inner end 12a thereof abuts the lower surface of the sunshade 4 with a constant rubbing force, so that the sunshade 4 has a constant amount necessary for forward and backward sliding operations. It is designed to give resistance. In other words, because of this resistance, the sunshade 4 will not be displaced even if it is stopped at an intermediate position of the roof opening 2. Further, rattling of the sunshade 4 when the vehicle is traveling can be reliably prevented by contact with the headlining 11.

[0006]

Conventionally, the soft skin portion 1 at the inner end 12a of the headlining 11 is as described above.
By bringing 3 into contact with the lower surface of the sunshade 4, a constant resistance force necessary for the sunshade 4 was obtained. However, the position of the inner end 12a of the headlining 11 causes a mounting error of the headlining 11 or Since the head lining 11 is likely to change due to deformation or the like, the necessary resistance force as described above may not be reliably obtained when the head lining 11 is not mounted properly. If the resistance is too weak, the sunshade 4 will open or close while the vehicle is running, and if it is too strong, a strong force will be required to open and close the sunshade 4, which is disadvantageous in terms of operability. Becomes

The present invention has been made in view of such a conventional technique, and provides a sunroof structure for an automobile in which the resistance applied to the sunshade is always constant.

[0008]

According to a first aspect of the present invention, a frame is provided at least at both left and right sides of a roof opening portion in which an opening / closing lid and a sunshade having a lower skin portion are slidably provided in front and rear, respectively. A rail portion for supporting the drive wire of the opening / closing lid is formed on the frame, and a guide portion in which an end engaging portion of the sunshade is slidably engaged with the inner side surface of the rail portion in the front-rear direction is formed. Protruding along and below the frame

[0012]

According to the invention described in claim 1 , both the guide portion with which the terminal engaging portion of the sunshade is engaged and the rising portion having a crank-shaped cross section which abuts the lower skin portion of the sunshade are the frame. Since it is in the state of being formed in (1), an error is unlikely to occur in the positional relationship between the two, and a constant positional relationship can be obtained. Therefore, the sliding contact force generated between the lower skin portion of the sunshade and the rising portion having a crank-shaped cross section can be maintained constant. Also, in the headlining

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to FIG. The same parts as those in the prior art are designated by the same reference numerals, and a duplicate description will be omitted.

From the inner surface of the frame 14 according to this embodiment, a rising portion 15 having a constant height h and having a crank-shaped cross section is integrally extended. The frame 14 is an integrally molded aluminum product including the rising portion 15 and the rail portion 7. Therefore, the positional relationship between the rising portion 15 and the rail portion 7 (the guide rib 8 as the “guide portion”) in the frame 14 is always a constant value as designed. The rising portion 15 is lower than the guide rib 8 and is set to a height at which the sun shade 16 supported between the rising portion 15 and the guide rib 8 can be opened and closed. More specifically, the fixed height h is set to such a degree that the lower soft skin portion (lower skin portion) 16a provided on the lower surface of the sunshade 16 is slightly pressed. By abutting on the side soft skin portion 16a, a constant rubbing force (resisting force) is always obtained. Therefore, it is possible to always obtain a constant resistance force required for opening / closing operation of the sunshade 16 without being prevented from being unable to obtain a constant resistance force due to an attachment error or deformation of a component that abuts on the sunshade 16 unlike the conventional case. Becomes

A head lining 17 composed of a core material 18 and a soft skin portion 19 is provided below the frame 14 as in the conventional case. The head lining 17 rises above the opening 17a of the head lining 17. Inner edge 1
8a does not come into contact with the sunshade 16, but just comes into contact with the lower surface of the horizontal portion 15a as the "inner end" of the rising portion 15. In addition, the inner end 18a of the headlining 17 has a vertical portion 15b of the rising portion 15.
However, since the inner end 18a of the head lining 17 is regulated by the rising portion 15 in both the vertical direction Z and the horizontal direction X, the position of the inner end 18a of the head lining 17 is regulated. Therefore, the positioning of the headlining 17 is ensured, and the headlining 1 seen from the vehicle interior is
The appearance of 7 is improved.

Further, the head lining 17 according to this embodiment has a sunshade 16 that moves back and forth as in the conventional case.
Therefore, the headlining 17 does not receive a force from the sunshade 16 in the front-rear direction. Therefore, there is no possibility that the headlining 17 is displaced in the front-rear direction. Also, headlining 1
It is also possible to prevent breakage of the soft outer skin portion 19 at the inner end 18a of 7 due to rubbing.

In addition, since the headlining 17 does not contact the sunshade 16, the inner end 18a of the headlining 17 is not pushed downward by the sunshade 16. Therefore, the inner end 18a of the headlining 17 is
It is possible to reduce the size of the surface fastener M without adding a load to the surface fastener M supporting the vicinity.

[0021]

[0022]

The sunroof structure for an automobile according to the present invention has the contents described above, and the rail portion (guide portion) for supporting the terminal engaging portion of the sunshade.
Since both the rising portion and the rising portion that abut on the lower surface skin portion of the sunshade are in a state of being provided in the frame, an error is unlikely to occur in the positional relationship between the two, and a constant positional relationship can always be obtained. Therefore, the rising portion formed so as to come into contact with the lower skin portion of the sunshade with a constant rubbing force always maintains the constant rubbing force, so that the sunshade operating force can be stabilized and the sunshade position is displaced. It is possible to reliably prevent rattling and rattling.
