(Installation procedure)
Next, a procedure for attaching the pillar garnish 50 to the pillar 60 using the tether clip 10 will be outlined.

  First, after the anchor portion 30 of the tether clip 10 is inserted into the insertion hole 54X formed through the bottom wall 54A of the tether storage portion 54 shown in FIG. 2 and the anchor portion 30 is rotated 90 degrees around the axis, The tether portion 20 and the engagement holding portion 40 are inserted into the insertion hole 54X. Then, the engagement holding part 40 is engaged with the long side edge part of the insertion hole 54X. Thereafter, the retaining portion 14 of the tether clip 10 is fastened to the clip mounting hole 62X of the pillar inner panel 62, whereby the pillar garnish 50 is attached to the pillar 60.

  A longitudinal intermediate portion (not shown) of the garnish main body 52 is fastened to the pillar inner panel 62 with another clip (not shown). Further, a lower end portion (not shown) of the garnish main body 52 is inserted into an insertion hole formed at an outer end portion in the vehicle width direction of an instrument panel (not shown).

(Action / Effect)
Next, operations and effects when the pillar garnish 50 is attached to the vehicle pillar 60 using the tether clip 10 will be described.

  When the curtain airbag 70 shown in FIG. 3 is deployed at the time of a side collision or rollover, the pillar garnish 50 tends to move away from the pillar 60 due to the deployment pressure of the curtain airbag 70. When the long side edge portion of the insertion hole 54X of the pillar garnish 50 is detached from the engagement holding portion 40 of the tether clip 10 and the pillar garnish 50 moves in a direction away from the pillar 60, the insertion hole 54X of the pillar garnish 50 is moved. The tether portion 20 passes, and finally the anchor portion 30 (see FIG. 2) is locked to the edge of the insertion hole 54X of the pillar garnish 50 (not shown).

  Here, of the pair of engagement holding portions 40 shown in FIG. 2, the second engagement holding portion 40B constituting the vehicle front lower side protrudes from the central wall portion 44B (see FIG. 1) to the vehicle front lower side. The rib 46 is provided, and the rib 46 is in contact with the inner surface on the short side of the insertion hole 54X. For this reason, without changing the position where a pair of engagement holding | maintenance part 40 is engaged with the long side edge part of the penetration hole 54X from the existing setting (optimized setting), the penetration hole 54X is the vehicle front lower side. Even if the tether clip 10 is extended, the tether clip 10 can be prevented from rattling with respect to the insertion hole 54X. Further, by not changing the position where the pair of engagement holding portions 40 are engaged with the long side edge portion of the insertion hole 54X from the existing setting, the engagement holding portions are deployed when the curtain airbag 70 (see FIG. 3) is deployed. Mode control when 40 is removed from the insertion hole 54X is maintained well. Further, the insertion hole 54X extends to the front lower side of the vehicle, thereby suppressing interference resistance between the curved portion 24R of the tether portion 20 and the bottom wall 54A of the pillar garnish 50 when the curtain airbag 70 (see FIG. 3) is deployed. It is done.

  Further, in the present embodiment, the curved portion 24R of the tether portion 20 bulges to the vehicle front lower side (see arrow X), which is the same direction as the rib 46 projects from the central wall portion 44B (see FIG. 1). The end portion of the bending portion 24R on the vehicle front lower side is set to a position overlapping the rib 46 when viewed from the direction facing the first surface 12A of the seat portion 12. For this reason, even if the amount of bulging of the curved portion 24R is increased and the length of the tether portion 20 disposed in the tether storage portion 54 is increased, the tether portion relatively moves when the curtain airbag 70 is deployed. Interference between the 20 curved portions 24R and the peripheral portion of the insertion hole 54X is prevented or effectively suppressed. Note that the movement trajectory of the left end portion in the drawing of the curved portion 24R of the tether portion 20 generally corresponds to the two-dot chain line 36.

  As described above, according to the present embodiment, the interference resistance between the curved portion 24R of the tether portion 20 and the surrounding portion of the insertion hole 54X of the pillar garnish 50 is reduced when the curtain airbag 70 (see FIG. 3) is deployed. However, it is possible to improve the mode control when the engagement holding portion 40 comes out of the insertion hole 54X when the curtain airbag 70 is deployed.

  In the present embodiment, the second end 46B of the rib 46 shown in FIG. 1 has an inclined surface 46S inclined toward the first end 46A in the direction in which the rib 46 protrudes from the central wall 44B. Is formed. Therefore, when the tether clip 10 is brought close to the bottom wall 54A of the tether storage portion 54 of the pillar garnish 50 shown in FIG. 2 from the outside of the tether storage portion 54 and the tether clip 10 is assembled to the pillar garnish 50, the rib 46 Even if the second end portion 46B of the second end portion 46B hits the peripheral portion of the insertion hole 54X of the bottom wall 54A, the tether clip 10 is guided to the assembly position by the inclined surface 46S formed in the second end portion 46B. Thereby, the assembly | attachment property of the tether clip 10 to the penetration hole 54X of the pillar garnish 50 can be improved.

  In this embodiment, the rib 46 is formed in the tether clip 10, so that, for example, the pillar garnish in which the insertion hole is formed penetrating on the assumption that the tether clip not including the rib (46) is assembled. It is also possible to prevent the tether clip 10 from being assembled by mistake.
