(First embodiment of fixing structure of mounting part, backboard and vehicle seat)
1st Embodiment of the fixing structure of a mounting component of this invention, a backboard, and a vehicle seat is described based on FIGS. FIG. 1 shows a vehicle seat having a backboard to which a fixing structure for mounting parts according to the present invention is applied.

  In FIG. 1, a vehicle seat 1 includes a seat cushion 2, a seat back 3 connected to the rear end of the seat cushion 2, and a headrest 4 attached to an upper portion of the seat back 3. The seat cushion 2 is a portion on which a person's buttocks ride. The seat back 3 is a portion against which a person's back hits. The headrest 4 is a part that receives a human head.

  The headrest 4 is detachably provided on the upper surface of the seat back 3. The lower part of the side surface of the seat cushion 2 is covered with a side cover 5. The side cover 5 covers a mechanism provided at the lower part of the seat cushion 2. A reclining lever 6 is provided on the side surface of the seat cushion 2. The tilt angle of the seat back 3 with respect to the seat cushion 2 can be adjusted by rotating the reclining lever 6 about the center line X0 by a predetermined angle.

  The seat back 3 includes a frame 7 that is a skeleton structure, a pad 8 that is supported by the frame 7, and a skin 9 that covers the pad 8. The frame 7 is made of, for example, hard metal or hard synthetic resin. The pad 8 is made of an elastic material such as urethane. The skin 9 is made of a soft material such as leather, leather, synthetic leather, cloth, fabric, or a combination thereof.

  A backboard 13 is provided on the back surface of the seat back 3. FIG. 2 is an enlarged view of the backboard 13. FIG. 3 is a cross-sectional view taken along line AA of FIG. In FIG. 1, the backboard 13 is fixed to the frame 7. The skin 9 of the seat back 3 has an opening at a portion corresponding to the back board 13. As shown in FIGS. 2 and 3, the backboard 13 is provided on the base 14 having substantially the same shape as that of the backboard 13, the skin 15 covering the surface of the base 14, and the upper part of the backboard 13. A decorative part 16 as an attachment part, for example, a wood grain plate 16 is provided.

  The reason why the skin 15 is stretched on the surface of the backboard 13 is to impart a high-class feeling to the vehicle seat. In the present embodiment, the base body 14 whose surface is covered with the skin 15 is the counterpart.

  The skin 15 is bonded to the surface of the substrate 14. In addition, when the base 14 is manufactured by molding using a mold, the skin 15 is previously placed in the mold so that the skin 15 is simultaneously attached to the surface of the base 14 simultaneously with the molding of the base 14. It can also be made.

  The base 14 is made of hard metal, hard synthetic resin, or the like. The base 14 has a constant thickness as a whole, and the front surface (the front surface of the hand in FIG. 2, the left side surface in FIG. 3) is swollen as a whole, and the back surface (the back side surface in FIG. 2, the right side surface in FIG. 3). ) Is generally recessed. The skin 15 is made of a flexible material such as leather, leather, synthetic leather, cloth, fabric, or a combination thereof. The decorative component 16 is formed of a synthetic resin that has been subjected to predetermined printing (for example, printing of wood). A central portion on the front side of the backboard 13 (front side in FIG. 2, left side in FIG. 3) is slightly depressed, and a pocket 17 is attached to the recessed portion.

  In FIG. 2, the decorative component 16 is elongated at almost the entire width in the upper end portion of the backboard 13. The decorative component 16 is fixed to the base body 14 from above the skin 15 by a plurality of fixing structures 21 provided along the longitudinal direction thereof. FIG. 4A shows a cross-sectional structure of the upper portion of the backboard 13 according to the line BB in FIG. FIG. 4B shows the fixing structure 21 in an exploded state.

In FIG.4 (b), the fixing structure 21 has the insertion protrusion part 22 which protrudes from the back surface of the decoration component 16 as an attachment part, and the attachment component receiving part 23 which protrudes from the back surface of the base | substrate 14 as a counterpart . And a tapping screw 24 as a tightening means. The insertion protrusion 22 is a cylindrical protrusion. A pilot hole 25 for receiving the screw portion 24 a of the tapping screw 24 is provided at the distal end of the insertion protrusion 22. The pilot hole 25 is a hole that is smaller than the outer diameter of the screw portion 24 a of the tapping screw 24. When the threading process by the tapping screw 24 is stable, the pilot hole 25 is not necessarily provided.

  The attachment part receiving part 23 is a cylindrical projection. The inside of the attachment part receiving part 23 is a cylindrical hollow part. As shown in FIG. 4A, the insertion protrusion 22 fits in the hollow portion without rattling. The tapping screw 24 is a screw having a function of entering the inside of the object while tapping itself.

  The function to be achieved by the fixing structure 21 is to fasten the decorative part 16 to the base body 14. In order to fulfill this function, the insertion protrusion 22 and the attachment part receiving part 23 are not necessarily essential requirements. If there is a screw 24 as a fastening means, the decorative component 16 can be fastened to the base 14.

Since the backboard 13 of the present embodiment is configured as described above, when the decorative component 16 is fixed to the base body 14 (that is, the counterpart) with the skin 15 attached in FIG. First, the insertion protrusion 22 of the decorative component 16 is inserted into the hollow space of the attachment component receiving portion 23 from the front side of the backboard 13 (left side in FIG. 4B). Next, the tapping screw 24 is screwed into the prepared hole 25 of the insertion protrusion 22 from the back side of the back board 13 (right side in FIG. 4B).

  At this time, the tapping screw 24 enters the insertion protrusion 22 of the decorative component 16 while tapping itself. Eventually, the entry of the tapping screw 24 into the insertion protrusion 22 stops while the head portion 24b of the tapping screw 24 presses the end surface of the attachment component receiving portion 23 as shown in FIG. In this state, the tapping screw 24 fastens the decorative part 16 as an attachment part to the base 14 from the back side of the base 14 as a counterpart. At this time, the decorative component 16 is in pressure contact with the skin 15 so as to have an indentation dimension δ as shown in the enlarged view.

  If the lock knob garnish as a mounting part is simply fitted in the recess of the seat back that is the counterpart as in Patent Document 2, it will be installed due to insufficient fitting force between the mounting part and the counterpart when the skin is pulled. There is a problem in that the edge of the part floats and a gap is generated between the attachment part and the counterpart.

  Further, even when the operation part of the unlocking mechanism as the attachment part is fixed to the frame of the seat back as a counterpart by a screw as in Patent Document 1, the fixing point is separated from the joint point between the skin and the operation part. However, when the skin is pulled, there is a problem that the edge of the mounting part floats and a gap is generated.

  On the other hand, in the present embodiment, the decorative part 16 as the attachment part is directly and strongly pulled in with the screw 24 from the back side of the base body 14 as the counterpart, and the decorative part 16 is pushed into the skin 15 of the backboard 13. Strong interference is caused by δ (see the enlarged view of FIG. 4A). Since the skin 15 is sandwiched between the decorative parts 16 that are resin parts in this way, even if tension is applied to the skin 15 after assembly, the terminal of the skin 15 is pulled out of the decorative part 16. Absent.

  Further, in the present embodiment, it is possible to take measures against the gap of the decorative part 16 with only the screws for assembling the parts, that is, the fastening means, and no parts other than the fastening means are required, so the structure is simple and the assembly is performed. Is easy and the cost can be kept low.

(Modification 1)
In the above embodiment, the tapping screw 24 is used as the fastening means as shown in FIG. However, instead of the tapping screw 24, an ordinary screw is used, a female screw is formed on the insertion protrusion 22 of the decorative component 16 as an attachment component, and the decorative component 16 is screwed with the male screw and the female screw. Can also be fastened to the base 14.

(Modification 2)
In the above embodiment, as shown in FIG. 4A, a female screw is provided on the side of the decorative part 16 as an attachment part, and a male screw is provided on the base 14 side as a counterpart. However, instead of this, a male screw can be provided on the decorative component 16 side and a female screw can be provided on the base 14 side as a counterpart. In this case, since the decorative part 16 that is a male screw cannot be rotated, the nut that is the female screw is screwed into the male screw part of the decorative part 16 from the back side of the base 14. Conceivable.

(Second embodiment of fixing structure of mounting part)
FIG. 5 shows another embodiment of the present invention relating to a fixing structure of a mounting part.

An opening 31 for passing the seat belt 29 is opened in the side wall 30, and a decorative part 26 as an attachment part is provided around the opening 31. The side wall 30 has a base 32 and a skin 33 that covers the base 32.

  The decorative component 26 as an attachment component has an elliptical shape or an oval shape when seen in a plan view, and has a bulge when viewed from the side. The decorative component 26 is formed of, for example, a synthetic resin, and a desired color or pattern is provided on the surface thereof by printing or the like. The decorative component 26 is fixed to the side wall 30 as a counterpart from the back side by a plurality of fixing structures 21. As the fixing structure 21, the fixing structure 21 already described with reference to FIGS. 4A and 4B can be used.

  Also in this embodiment, the decorative component 26 as an attachment component is directly and strongly pulled in with the screw 24 (see FIGS. 4A and 4B) from the back side of the base body 32 as a counterpart, and the decorative component 26 is removed. The skin 33 is strongly interfered with the pressing amount δ (see the enlarged view of FIG. 4A). Since the skin 33 is sandwiched between the decorative parts 26, which are resin parts, the end of the skin 33 is pulled out of the decorative part 26 even if tension is applied to the skin 33 after assembly. Absent.

  Further, in this embodiment, it is possible to take measures against the gap of the decorative part 26 with only the screws for assembling the parts, that is, the fastening means, and no parts other than the fastening means are required, so the structure is simple and the assembly is performed. Is easy and the cost can be kept low.
