[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the ducted ceiling interior member 10 of the present embodiment is attached to a vehicle 90, and a duct 30 for blowing air from a car air conditioner (not shown) in the vehicle is provided on the back side (upper side). I have. The duct 30 has a U shape in plan view, and is disposed on both sides and the rear of the vehicle 90. The rear portion of the duct 30 communicates with the car air conditioner, and a plurality of air discharge ports (not shown) are provided on the front side (lower side) of the ceiling interior member 11.

  As shown in FIGS. 1 and 2, the ducted ceiling interior member 10 has a duct-forming member 20 on the back-side upper surface 11M of the flat ceiling interior member 11 (corresponding to “the back surface of the ceiling interior member” of the present invention). Has a fixed structure. Specifically, as shown in FIG. 2, the duct forming member 20 has a groove-shaped structure and includes a flange portion 22 that protrudes laterally from the opening edge of the groove 21. And this collar part 22 is fixed to the back side upper surface 11M by the hot melt adhesive 41 (corresponding to the “adhesive” of the present invention), the opening of the groove 21 is closed by the ceiling interior member 11, and the above-mentioned A duct 30 is formed. The hot melt adhesive 41 is interposed between the outer edge portion 22 </ b> A of the flange portion 22 and the ceiling interior member 11, and is scattered in the circumferential direction of the flange portion 22.

  As shown in FIG. 3A, the flange portion 22 has a stepped shape in which the inner edge portion 22B is recessed from the ceiling interior member 11 with respect to the outer edge portion 22A, and the receiving recess 25 is formed in the recessed portion. Is formed. The ceiling interior member 11 and the duct forming member 20 are sandwiched between the back surface 25M of the receiving recess 25 and the back side upper surface 11M of the ceiling interior member 11 by an elastic seal member 50 such as, for example, soft urethane foam. The gap between them is sealed to prevent air leakage of the duct 30 (see FIG. 2).

  Here, as shown in FIG. 3B, the depth of the receiving recess 25 is smaller than the thickness of the elastic seal member 50 that is not elastically deformed. In the state shown in FIG. The member 50 is compressed and deformed. The elastic seal member 50 is fixed to the inner surface 25M of the receiving recess 25 by a double-sided tape 51.

  The description about the structure of the ceiling interior member 10 with a duct is above. According to the ceiling-equipped interior member 10 with the duct according to the present embodiment, the elastic seal member 50 is received in the receiving recess 25 in which a part of the flange 22 is depressed, so that the flange 22 is fixed to the ceiling interior member 11. In doing so, the elastic seal member 50 is suppressed from being excessively compressed. Thereby, peeling of the collar part 22 can be prevented. Further, the amount of compressive deformation of the elastic seal member 50 can be easily adjusted by changing the depth of the receiving recess 25.

  Next, the manufacturing method of the ceiling interior member 10 with a duct is demonstrated. In order to manufacture the ceiling interior member 10 with a duct, first, the receiving concave portion 25 is formed in the flange portion 22 of the duct forming member 20. Specifically, the duct forming member 20 is manufactured by vacuum forming or press forming of a sheet material, and at the time of forming, the inner edge portion 22B of the flange portion 22 is depressed to form the receiving recess 25 (FIG. 3 ( A)). By forming the receiving recess 25, the flange portion 22 has a stepped shape, and the strength of the flange portion 22 is increased.

  Next, the elastic seal member 50 is fixed to the inner surface 25 </ b> M of the receiving recess 25 with the double-sided tape 51. At this time, the elastic seal member 50 partially protrudes from the receiving recess 25 (see FIG. 3B).

  Next, the flange portion 22 is fixed to the back side upper surface 11 </ b> M of the ceiling interior member 11. Specifically, first, as shown in FIG. 4, the flange portion 22 is assigned to the back side upper surface 11M of the ceiling interior member 11 from above, and the elastic seal member 50 protruding from the receiving recess 25 is pushed to the back side upper surface 11M. Hit it. At this time, a gap 43 is formed between the outer edge portion 22A of the flange portion 22 and the back-side upper surface 11M. And after inject | pouring the hot-melt-adhesive 41 into this clearance gap 43 with the nozzle 40, the collar part 22 is pressed against the ceiling interior member 11, and is fixed. Thereby, the ceiling interior member 10 with a duct is obtained. The hot melt adhesive 41 is injected so as to be scattered at a plurality of locations on the flange portion 22.

  Here, when the flange portion 22 is abutted against the elastic seal member 50, since the amount of compressive deformation of the elastic seal member 50 is small, a gap is formed between the flange portion 22 and the ceiling interior member 11. After injecting the hot melt adhesive 41 into the gap, the flange portion 22 is further pressed against the ceiling interior member 11 side so that the amount of compressive deformation of the elastic seal member 50 becomes a predetermined value.

  According to the method for manufacturing the ducted ceiling interior member 10, the hot melt adhesive 41 is applied to the bonding surface of either the flange portion 22 or the ceiling interior member 11, and then the flange portion 22 and the ceiling interior member 11 are bonded. Compared with the case where it does, it is prevented that the hot-melt-adhesive 41 hardens | cures before adhere | attaching the collar part 22 and the ceiling interior member 11, and can improve adhesive strength.

  FIG. 5 shows another method of fixing the flange portion 22 to the back side upper surface 11M of the ceiling interior member 11. In this method, first, as shown in FIG. 5 (A), the opening of the groove 21 of the duct forming member 20 is directed upward, and the adhesive surface of the flange 22 with the ceiling interior member 11 is disposed on the upper side. Then, the hot melt adhesive 41 is applied to the upper surface of the outer edge portion 22 </ b> A of the flange portion 22. Here, as described above, since the elastic seal member 50 protrudes from the receiving recess 25, the hot melt adhesive 41 is prevented from flowing to the groove 21 side. That is, the elastic seal member 50 serves as a weir that prevents the hot melt adhesive 41 from flowing into the groove 21.

  When the hot melt adhesive 41 is applied to the flange portion 22, the flange portion 22 reaches the rear upper surface 11 </ b> M of the ceiling interior member 11 and is fixed. Specifically, as shown in FIG. 5B, the ceiling interior member 11 is pressed from above the duct forming member 20, and the outer edge portion 22 </ b> A of the flange portion 22 is hot-melt bonded to the back side upper surface 11 </ b> M of the ceiling interior member 11. Fix with agent 41. Thereby, the ceiling interior member 10 with a duct is obtained. When the ceiling interior member 11 is pressed against the duct forming member 20, the elastic seal member 51 comes into contact with the back-side upper surface 11M and is compressed and deformed.

  According to the method for manufacturing the ducted ceiling interior member 10 shown in FIG. 5, the hot melt adhesive 41 applied to the flange portion 22 using the elastic seal member 50 as a weir can enter the groove 21 of the duct forming member 20. It is prevented. Accordingly, the amount of useless hot melt adhesive 41 that does not contribute to the adhesion between the flange portion 22 and the ceiling interior member 11 can be reduced, and the adhesive strength can be stabilized. This is particularly useful when the flange 22 is inclined so as to descend toward the groove 21 of the duct forming member 20.
