However, in the structure shown in FIG. 3, the thickness of the opening terminal portion 921 of the ceiling material 92 is large. Therefore, when the sunshade 962 is opened, the occupant hooks and pulls a hand (finger) on the opening terminal portion 921 of the ceiling material 92. The ceiling material 92 may be broken.
In addition, in the structure shown in FIG. 4, since the passenger cannot pull the opening terminal portion 921 of the ceiling material 92 by hand, there is no fear that the ceiling material 92 will be broken. Therefore, the number of parts and the number of assembling steps increase, resulting in problems of cost increase and workability deterioration.
3 and 4 are common to the same functional units.

  The present invention has been made in view of such conventional problems, and has a ceiling material terminal structure that can prevent the ceiling material from being bent by pulling the opening terminal portion of the ceiling material while having a simple structure. It is something to be offered.

The present invention has an opening corresponding to a sunroof provided on a vehicle body, and a ceiling material terminal structure in which a reinforcing material is provided on the periphery of the opening to increase rigidity.
The ceiling material is composed of a base material and a skin covering the surface of the base material on the passenger compartment side, and the reinforcing material is formed on the surface of the base material opposite to the passenger compartment side at the peripheral edge of the opening. It is disposed so as to cover the end surface of the base material, and is extended so as to protrude from the end surface of the base material, and has a reinforcing extension portion having a thickness smaller than the end portion of the base material,
The reinforcing extension part is covered so as to be wrapped in a skin extension part formed by extending the skin from the end part of the base material, and the tip of the reinforcement extension part covered by the skin extension part Part is an open terminal,
The opening terminal portion is in the terminal structure of the ceiling material, which is close to a housing member of a sunshade disposed on the body so as to be located around the opening of the ceiling material (claim) Item 1).

  In the terminal structure of a ceiling material according to the present invention, the reinforcing material is extended so as to protrude from the end surface of the base material of the ceiling material at the periphery of the opening, and has a thickness greater than that of the end portion of the base material. Has a small reinforcing extension. The reinforcing extension part is covered so as to be wrapped in the skin extension part of the skin of the ceiling material, and the distal end part of the reinforcement extension part covered by the skin extension part is an open terminal part. . And this opening terminal part is adjoining to the housing member of a sunshade.

  That is, the opening end portion of the ceiling material at the periphery of the opening is configured to cover the reinforcing extension portion of the reinforcing material having a thickness smaller than the end portion of the base material of the ceiling material with the skin of the ceiling material. It is configured. Therefore, it becomes possible to reduce the thickness of the opening end portion of the ceiling material, and when opening the sunshade, it is possible to prevent an occupant from catching a hand (finger) on the opening end portion of the ceiling material. it can. Thereby, it can prevent that the opening terminal part of the said ceiling material cannot be pulled easily.

  Moreover, the opening terminal part of the said ceiling material is adjoining with the housing member of a sunshade, and makes the clearance gap small. Therefore, when the sunshade is opened, it is difficult for the occupant to put a hand (finger) between the opening terminal portion of the ceiling material and the housing member of the sunshade. Thereby, it can prevent that the opening terminal part of the said ceiling material cannot be pulled easily.

  In addition, the opening end portion of the ceiling material is not covered with another member such as a mall so that the occupant cannot easily pull the opening end portion of the ceiling material as in the conventional case. do not do. That is, by adopting the structure of the present invention, the opening end portion of the ceiling material is a simple structure that is exposed without being fixed to the housing member or the like of the sunshade. It is possible to sufficiently exert the effect of preventing the wire from being pulled easily.

  Thus, according to the terminal structure of the ceiling material of the present invention, the opening terminal portion of the ceiling material cannot be easily pulled while being a simple structure. And it can prevent that a passenger | crew pulls the opening terminal part of the said ceiling material with a hand, and a folding generate | occur | produces in this ceiling material.

In this invention, it is preferable that the thickness of the said reinforcement extension part is 30 to 70% of the thickness of the edge part of the said base material (Claim 2).
In this case, it is possible to sufficiently reduce the thickness of the opening terminal portion of the ceiling material, and it is possible to further prevent an occupant from catching a hand (finger) on the opening terminal portion of the ceiling material.

  Moreover, when the thickness of the reinforcing extension portion is less than 30% of the thickness of the end portion of the base material, there is a possibility that the strength of the reinforcing extension portion cannot be sufficiently ensured. On the other hand, when the thickness of the reinforcing extension portion exceeds 70% of the thickness of the end portion of the base material, the thickness of the opening terminal portion of the ceiling material may not be sufficiently reduced.

Moreover, the proximity state of the opening end portion of the ceiling material and the housing member of the sunshade is preferably as the gap in the width direction of both is small, and the height positions of both are preferably the same. It is difficult to avoid some variation due to errors.
In addition, it is preferable that both the gap | interval of the width direction of said both and the deviation | shift amount of a height position are smaller than the thickness of the edge part of the said base material. Thereby, it can prevent that the opening terminal part of the said ceiling material cannot be pulled easily.

The terminal structure of the ceiling material concerning the Example of this invention is demonstrated using figures.
As shown in FIGS. 1 and 2, the terminal structure 1 of the ceiling material of the present example has an opening 20 corresponding to a sunroof 61 provided on the body of the vehicle, and increases the rigidity at the periphery of the opening 20. It is the terminal structure of the ceiling material in which the reinforcing material 5 is disposed.
This will be described in detail below.

As shown in FIG. 1, the ceiling member 2 has an opening 20 provided corresponding to the sunroof 61 (FIG. 2) at the front position and the intermediate position. Each of the openings 20 has a square shape. In addition, reinforcing members 5 for increasing the rigidity of the ceiling material 2 are disposed on the peripheral edges of the openings 20. The reinforcing material 5 is bonded to the ceiling material 2 with an adhesive such as hot melt.
In this example, the ceiling material 2 is made of a mixture of thermoplastic resin and wood fiber. The reinforcing material 5 is made of ABS resin.

Next, the structure of the ceiling material 2 at the periphery of the opening 20 will be described.
In this example, the ceiling material 2 at the periphery of the opening 20 provided at the front position and the intermediate position shown in FIG. 1 has the same structure.
Therefore, hereinafter, for convenience of explanation, the structure of the ceiling material 2 at the periphery of the opening 20 provided at the front position will be described.

  As shown in FIG. 2, the ceiling material 2 is configured by laminating a base material 3 and a skin 4. The base material 3 has a base material main body 31 formed in a substantially horizontal direction and a base material end 32 formed by rising substantially upward from the base material main body 31 at the periphery of the opening 20. Further, the skin 4 covers the surface of the base material 3 on the passenger compartment side (base material surface 301). In addition, the skin 4 has a skin extension portion 41 formed by extending from the base material end portion 32 of the base material 3.

Further, as shown in the figure, the reinforcing member 5 is formed on the periphery of the opening 20 on the surface opposite to the vehicle compartment side of the base material 3 (base material back surface 302) and the end surface of the base material 3 (opening end surface 303). It is arrange | positioned so that it may cover. Further, the reinforcing member 5 has a reinforcing extending portion 51 that is extended so as to protrude from the opening end face 303 of the base member 3 and has a smaller thickness than the base end portion 32 of the base member 3.
In this example, the thickness of the base end portion 32 of the base 3 is 3 mm, and the thickness of the tip 511 of the reinforcing extension 51 is 2 mm.

Moreover, the reinforcement extension part 51 of the reinforcing material 5 is covered so that it may be wrapped in the skin extension part 41 of the skin 4 whose thickness is 1 mm. The skin extension 41 is bonded to the reinforcing material 5 with an adhesive.
Further, the tip end portion 511 of the reinforcing extension portion 51 covered with the skin extension portion 41 of the skin 4 forms the opening terminal portion 21 of the ceiling material 2.

  As shown in the figure, a sunroof 61 made of a transparent glass plate is disposed above the opening 20 of the ceiling material 2 so as to cover the opening 20 of the ceiling material 2. A sunshade 62 for sunshading is disposed below the sunroof 61. The sunshade 62 is attached to a housing member 63 disposed around the opening 20 of the ceiling material 2 so as to be opened and closed.

And in this example, as shown in the figure, the opening terminal part 21 of the ceiling material 2 is adjoining to the inward protrusion part 64 of the housing member 63 to which the sunshade 62 is attached. That is, the gap between the opening terminal portion 21 and the housing member 63 is very narrow.
In this example, the gap is smaller than at least the thickness of the base end portion 32 of the base 3. Moreover, the position of the height direction of the opening terminal part 21 and the housing member 63 is set aiming at substantially the same height.

Next, the effect in the terminal structure 1 of the ceiling material of this example is demonstrated.
In the terminal structure 1 of the ceiling material of the present example, the reinforcing material 5 extends so as to protrude from the base material end surface 303 of the base material 3 of the ceiling material 2 at the periphery of the opening 20. The reinforcing extension 51 is smaller in thickness than the end 32. The reinforcing extension portion 51 is covered so as to be wrapped in the skin extension portion 41 of the skin 4, and the tip end portion 511 of the reinforcement extension portion 51 covered with the skin extension portion 41 becomes the opening terminal portion 21. ing. The opening terminal portion 21 is close to the housing member 63 of the sunshade 62.

  That is, the opening terminal portion 21 of the ceiling material 2 at the periphery of the opening portion 20 covers the reinforcement extending portion 51 of the reinforcing material 5 having a thickness smaller than the base material end portion 32 of the base material 3 with the skin 4 of the ceiling material 2. It is configured in this way. Therefore, the thickness of the opening terminal portion 21 of the ceiling material 2 can be reduced, and when the sunshade 62 is opened, the occupant hooks a hand (finger) on the opening terminal portion 21 (see FIG. 2) of the ceiling material 2. Can not be. Thereby, it can prevent that the opening terminal part 21 of the ceiling material 2 cannot be pulled easily.

  Further, the opening terminal portion 21 of the ceiling material 2 is close to the housing member 63 of the sunshade 62, and the gap is made small. Therefore, when the sunshade 62 is opened, it is difficult for the occupant to put a hand (finger) between the opening terminal portion 21 of the ceiling member 2 and the housing member 63 of the sunshade 62. Thereby, it can prevent that the opening terminal part 21 of the ceiling material 2 cannot be pulled easily.

  Further, the opening terminal portion 21 of the ceiling material 2 is covered with another member such as a mall so that the occupant cannot easily pull the opening terminal portion 21 of the ceiling material 2 as in the prior art. I won't do that. That is, by adopting the structure of this example, the opening terminal portion 21 of the ceiling material 2 is not fixed to the housing member 63 or the like of the sunshade 62, but is a simple structure in an exposed state. The effect of preventing the opening terminal portion 21 from being pulled easily can be sufficiently exhibited.

  Thus, according to the terminal structure 1 of the ceiling material of this example, it is possible to prevent the opening terminal portion 21 of the ceiling material 2 from being easily pulled while being a simple structure. And it can prevent that a passenger | crew pulls the opening terminal part 21 of the ceiling material 2 by hand, and a folding generate | occur | produces in the ceiling material 2. FIG.
