特開２００８−２１３７６８号公報記載の構成では、帯状縫製部、芯材がコンソールの溝に嵌合されて、帯状縫製部の位置ずれ、縫製のほつれが防止される。しかし、被覆したトリムカバー端末とともに縫製された芯材の嵌合される溝をコンソールのパッド表面に形成して、その溝に芯材を嵌合しており、トリムカバー端末、芯材の縫製に加えて縫製とは異なる別の行程(嵌合工程)が必要となり、作業工程が複雑化する。また、芯材が２つ必要となり、部材数が増える。さらに、２つの芯材がトリムカバー端末の間に介在されるため、帯状の縫製部が幅広となり、外観意匠上好ましくない。
In the configuration described in Japanese Patent Application Laid-Open No. 2008-2113768, the belt-shaped sewing portion and the core material are fitted into the groove of the console, and the belt-shaped sewing portion is prevented from being displaced and frayed. However, the fit is the groove of the core material which is sewn together with the trim cover terminal coated to form a console of the pad surface, and fitted to the core material in the groove, the trim cover terminal, the sewing of the core material In addition, a separate process (fitting process) different from sewing is required, which complicates the work process. Moreover, two core materials are required, and the number of members increases. Further, since the two core members are interposed between the trim cover terminals, the belt-shaped sewing portion becomes wide, which is not preferable in terms of appearance design.
図２（Ａ−３）に示すように、左右のトリムカバー片１４−２ａ、１４−２ｂは、芯材の玉縁２２の下半部を挟んで左右から覆うとともに下方に延ばされて芯材の縫製片２４に左右から重ねられる。そして、左右のトリムカバー片の端末(トリムカバー端末) １４−２ａ’、１４−２ｂ’が芯材の縫製片２４’に縫製されるとともに、芯材の玉縁２２に沿った左右のトリムカバー端末が玉縁を挟んで縫製されている。
すなわち、２枚のトリムカバー端末１４−２ａ’、１４−２ｂ’を芯材の縫製片２４’に縫製して第１の縫製部３０を形成するとともに、別の縫製工程によってトリムカバー端末が芯材の玉縁２２を挟んでさらに縫製されて第２の縫製部を形成し、トリムカバー端末が縫製片、玉縁のそれぞれに縫製された二重縫製となっている。
As shown in FIG. 2 (A-3), the left and right trim cover pieces 14-2a and 14-2b are covered from the left and right sides with the lower half of the bead 22 of the core material, and are extended downward. It overlaps with the sewing piece 24 of material from right and left. Then, terminals of the left and right trim cover pieces (trim cover terminals) 14-2a ′ and 14-2b ′ are sewn to the sewing piece 24 ′ of the core material, and the left and right trim covers along the edge 22 of the core material The terminal is sewn across the bead.
That is, the two trim cover terminals 14-2a ′ and 14-2b ′ are sewn to the sewing piece 24 ′ of the core material to form the first sewing portion 30, and the trim cover terminal is cored by a separate sewing process. Further sewing is performed across the ball edge 22 of the material to form a second sewing portion, and the trim cover terminal is double-sewn which is sewn to each of the sewing piece and the ball edge.
図２（Ｂ−１）に示すように、たとえば、芯材１２０は玉縁１２２が断面矩形形状とされ、玉縁が断面矩形形状であることを除けば、上記の芯材２０と同様の形状に成形され、２枚のトリムカバー片が同様の方法で芯材を介在して縫製される。
すなわち、芯材１２０は、プラスチックなどからなる断面矩形形状の玉縁１２２と、玉縁をカバー１２４で被覆してカバーの端末を重ねて延ばした縫製片１２４’とを有した断面略鍵穴形状に成形されている。そして、左右のトリムカバー片１４−２ａ、１４−２ｂが、芯材の玉縁１２２の下半部を挟んで左右から覆って下方に延ばされて芯材の縫製片２４に左右から重ねられ、トリムカバー端末が芯材の縫製片１２４’に縫製されるとともに、芯材の玉縁１２２に沿った左右のトリムカバー端末が玉縁を挟んで縫製されている。
As shown in FIG. 2 (B-1), for example, the core material 120 has the same shape as the core material 20 except that the bead 122 has a rectangular cross section and the bead has a rectangular cross section. The two trim cover pieces are sewn with the core material interposed in the same manner.
That is, the core material 120 has a substantially cross-sectional keyhole shape having a bead 122 having a rectangular cross section made of plastic or the like, and a sewing piece 124 ′ that is formed by covering the bead with a cover 124 and extending the end of the cover. Molded. Then, the left and right trim cover pieces 14-2a and 14-2b are covered from the left and right sides of the lower half of the core edge 122 and are extended downward to be overlapped on the core sewing piece 24 from the left and right. The trim cover terminal is sewn to the core piece 124 ', and the left and right trim cover terminals along the core edge 122 are sewn with the bead interposed therebetween.
芯材１２０の玉縁１２２が断面矩形形状であっても、強固に縫製されて、縫製のほつれが確実に防止されるとともに、良好な外観意匠が得られるなど、玉縁が断面円形形状における場合と同様の効果が得られる。
Also welt 122 of the core 120 is a cross-sectional rectangular shape, is firmly sewn, with frayed sewing can be reliably prevented, and good appearance design is obtained, if the welt is in a circular cross-section shape The same effect can be obtained.
