As shown in FIGS. 1 to 4, the seat includes a seat back SB that can tilt with respect to the seat cushion SC, and a headrest HR is disposed above the seat back SB.

  For example, the headrest HR is molded into a predetermined shape by a press in a state in which a synthetic resin is coated on a nonwoven fabric, and the foam cover injected into the trim cover 3 is cured by the trim cover 3 having a shape-retaining property. And a stay 1 a that is formed on the headrest frame 1 fixed in the pad body 2 and extended from the trim cover 3.

  For example, the seat back SB is formed into a predetermined shape by a press in a state in which a synthetic resin is coated on a nonwoven fabric, and thereby a trim cover 11 having a shape retaining property, and a pad body 10 to be loaded into the trim cover 11. The seat back frame 2 fixed in the pad body 10 and the upper frame 2a extending in the lateral direction at the upper end of the seat back frame 2 are fixed by welding, and the stay 1a is extended in the vertical direction and the upper portion of the stay 1a. A pair of left and right cylinders 5 to be supported by the frame 2a and the cylinders 5 are inserted into and locked with each other, and a head portion 6a is formed at the upper end so that the stay 1a can be inserted from above. It is mainly composed of a cylindrical headrest support 6 made of resin.

  The pad body 10 is formed integrally with the foamed liquid injected into the trim cover 11, and the pad body 10 is formed separately from the trim cover 11 and inserted into the trim cover 11. There is. In the present invention, both types of applications are possible.

  In addition, an insertion hole 7 b that allows insertion of the cylindrical headrest support 6 is formed in the top of the trim cover 11, and an insertion hole that enables insertion of the headrest support 6 also in the top of the pad body 10. 10b is formed. In order to enable insertion of the headrest support 6, the insertion hole 7 b on the trim cover 11 side and the insertion hole 10 b on the pad body 10 side are aligned.

  A recessed portion 20b provided in a molded-container-shaped fingertip insert 20 that allows insertion of the finger F of the hand H is embedded in the top of the seat back SB. A flange-like connecting portion 20a is formed on the peripheral edge of the opening 20c of the concave portion 20b of the fingertip insert 20. The fingertip insert 20 having such a configuration is formed into a container from a soft material made of a soft synthetic resin such as an elastomer that can be connected to the trim cover 11 by stitching.

  At the top of the trim cover 11, a mounting hole 7 a that allows the insertion of the concave portion 20 b of the fingertip insert 20 is formed. This mounting hole 7 a is arranged behind the insertion hole 7 b at the top of the trim cover 11. Yes. An insertion hole 10a that allows insertion of the recessed portion 20b of the fingertip insertion body 20 is also formed at the top of the pad body 10, and this insertion hole 10a is disposed behind the insertion hole 10b at the top of the pad body 10. Yes. And in order to make mounting | wearing of the recessed part 20b possible, alignment with the attachment hole 7a by the side of the trim cover 11 and the insertion hole 10a by the side of the pad body 10 is made.

  The connecting portion 20 a of the fingertip insert 20 is connected to the trim cover 11 by being sewn by a stitching portion R at the periphery of the mounting hole 7 a provided at the top of the trim cover 11. The connecting portion 20a is provided so as to be shifted from the upper end edge of the opening 20c of the fingertip insert 20 toward the bottom of the concave portion 20b by the thickness of the stitched end turned back to form the attachment hole 7a of the trim cover 11. It has been. By such stitching, the appearance quality of the mounting hole 7a of the trim cover 11 can be improved. And integration of the fingertip insert 20 and the seat back SB can be achieved easily and reliably.

  Since the fingertip insert 20 sewn to the trim cover 11 in this way is formed of a soft material, it is easily deformed by the force of the finger F of the hand H. Therefore, when the surrounding trim cover 11 is pulled by the deformation of the fingertip insert 20, the insertion hole 7b is exposed around the head portion 6a of the headrest support 6, and appearance defects such as wrinkles occur. Furthermore, the deformation of the concave portion 20b of the fingertip insert 20 due to the force of the finger F also leads to insufficient rigidity of the grip function.
