FIG. 2 is a cross-sectional view taken along line AA of FIG. 1 depicting a state in which the installation of the door trim to the door body is completed.

  First, in FIG. 1, an automobile door 1 includes a door body 4 configured to be able to open and close an upper window 3 by moving a window glass 2 up and down to open and close a doorway of a vehicle body, and a compartment of the door body 4. There is a door trim 5 mounted on the door body 4 to decorate the inside. Further, the windshield 2 is elastically moved so that rainwater or the like does not enter the vehicle interior between the upper end waist portion 6 of the door trim 5 and the window glass 2. A weather strip 7 for sealing in contact is provided.

  As shown in FIG. 5, the door main body 4 is configured by joining an inner panel 8 formed by mutually forming sheet metal by pressing or the like and an outer panel (not shown). A stiffener 9 as a strength rigid member located on the wind glass 2 side is attached to the upper end portion.

  A weather strip attachment piece 10 is formed at the upper end of the stiffener 9, and the weather strip 7 is attached by fitting the holding frame portion 7 a of the weather strip 7.

  As a result, the weather strip 7 has a seal tongue piece portion 7a-1 formed on the upper surface portion of the sandwiching frame portion 7a in elastic contact with the upper end waist portion 6 and a pair of glass side seal piece portions 7b formed on the side surface portions. In combination with the elastic contact with the glass 2, rainwater or the like entering between the wind glass 2 and the door trim 5 is sealed.

  The door trim 5 includes a trim core material 5a formed by molding a resin by injection molding or mold press molding, and a skin material 5b covering the surface of the core material 5a. The trim core material 5a includes: Although the whole may be integrally formed, the divided core pieces divided into two parts or three parts in the vertical direction are joined to each other, although not clearly shown in the figure due to the enlargement of the door 1 or the like. Is made up of. Therefore, for example, in FIG. 2, the trim core material 5 a is an upper-side divided core material piece located at the actual uppermost position.

  A door trim mounting piece 11 is formed at the upper end of the inner panel 8 so as to be located on the vehicle interior side, and is formed on a waist garnish 6 provided on the upper end waist 5c of the trim core 5a. The trim core member 5a is configured to be attached to the inner panel 8 by engaging the hook engaging piece 6a.

  As specifically shown in FIG. 2, the hook engaging piece 6a is formed by cutting out the bottom 6b-1 of the recessed portion 6b provided in the waist garnish 6 in a U-shape on the window glass 2 side. In addition, the vehicle interior side of the bottom portion 6 b-1 is used as a connecting swing portion 6 a-2, and the engaging protrusion 6 a-1 is swingable with respect to the waist garnish 6.

  Next, a process of mounting the door trim 5 configured by covering the trim core material 5a with the skin material 5b on the inner panel 8 of the door body 4 will be described.

When the front end of the hook engaging piece 6a is applied to the vehicle compartment side of the door trim attaching piece 11 and the door trim 5 is further moved in the direction of the arrow in FIG. 3, the hook engaging piece 6a is moved to the door trim attaching piece. 11, the engaging projection 6 a-1 swings upward by the wedge action and rides on the upper end of the door trim mounting piece 11. At this time, the space between the rear surface of the trim core 5a and the recessed portion 6b of the waist garnish 6 allows the hook engaging piece 6a to swing upward.

  When the door trim 5 is further moved from this state, the engagement protrusion 6a-1 gets over the upper end of the inner panel 8, and then the engagement protrusion 6a-1 snaps downward and instantaneously rotates behind the inner panel 8 (window). The glass side is engaged (the state shown in FIG. 5).

  In such a series of attachment processes of the door trim 5, the hook engaging piece 6 a is formed so as to be swingable with respect to the upper end waist portion 6 of the door trim 5. By forming the protrusion, when the hook engaging piece 6a engages with the door trim mounting piece 11 on the inner panel 8 side, the upper end waist portion 6 does not swing, and the upper end waist portion 6 becomes the weather strip 7. Since the sealing tongue piece 7a-1 is not pressed from the upper side, the sealing tongue piece 7a-1 always comes into elastic contact with a predetermined position of the upper end waist part 6 to seal the weather strip. There is no loss of performance.

  Next, a modification according to the present invention shown in FIGS. 6 to 9 will be described.

  The first modification shown in FIGS. 6 and 7 is the same as the above embodiment in that the hook engaging piece 6a is formed by notching the bottom 6b-1 of the recessed portion 6b into a U-shape. There is a difference, however, in that the connecting oscillating portion 6a-2 is positioned on the window glass 2 side.

  In the second modification shown in FIGS. 8 and 9, the hook engaging piece portion 6a is between two slits provided from the bottom portion 6b-1 of the recessed portion 6b to the vehicle interior side surface of the upper end waist portion 5c. It is different in that it is formed in a bridging shape and is constituted by an engaging protrusion 6a-1 formed by recessing the substantially central portion of the bridging shape downward. Since the two slits are provided from the bottom 6b-1 of the recessed portion 6b to the side facing the vehicle interior of the waist garnish 6, the hook engaging piece 6a can be more easily swung.

  In any of the modifications, the upper end waist portion 6 is not swung when the engagement protrusion 6a-1 is engaged with the door trim mounting piece portion 11, and is similar to the above embodiment.

  In the above embodiment, the stiffener 9 is provided in order to increase the upper rigidity of the inner panel 8. However, the stiffener 9 is not necessarily provided. For example, a configuration corresponding to the stiffener 9 is provided. In this case, the weather strip mounting piece 10 is directly formed on the inner panel 8.
