部位４２が乗員席側へ飛ばされることもあり得る。By the way, as shown in FIGS. 11 and 12, the support base portion 34 for fixing the clip 36 has a first wall portion 38 and a first wall portion 38 which are erected at a predetermined distance in the lateral direction of the pillar body 32. With the second wall portion 40, the pillar main body 3
It is connected to the back of 2. Therefore, the boundary portion between the pillar main body 32 and the support base portion 34 is in a direction that does not intersect with the pressing portion 42 that is deformed by the pressing force of the airbag support member 14, that is, in a direction substantially parallel to the pressing portion 42. It has an extended so-called N-shape. Therefore, as shown in FIG. 13, the pressing portion 42 that is allowed to be deformed by the pressing force of the airbag supporting member 14 is only the right side portion from the connecting portion of the support base portion 34 with the first wall portion 38. Therefore, the pressing portion 42 locally deforms with the boundary portion with the first wall portion 38 as a base point. Therefore, in the pillar garnish 30 formed of a relatively hard resin material such as polypropylene (PP), stress concentrates at the boundary portion between the pressing portion 42 of the pillar body 32 and the first wall portion 38. The pillar main body 32 may be broken and damaged at the boundary portion, and the separated pressing portion 42 may be blown to the passenger seat side.

エアバッグ１２の膨張展開が遅延して乗員保護機能が充
分に発揮され得ない畏れも指摘される。If the pillar body 32 is not damaged, the clip 36 is subjected to an excessive load when the pillar body 32 is deformed, even if the pressing portion 42 is prevented from separating and flying. Since it becomes hooked, there is a fear that the clip 36 is detached from the locking hole 17 and the pillar garnish 30 flies as a whole. Therefore, in order to prevent such inconvenience, it is necessary to use a special reinforced clip, which causes a problem of cost increase. Furthermore, since a large force is required to deform the pillar main body 32, the airbag support member 14 may not be smoothly extended to the passenger compartment, and the inflation and deployment of the airbag 12 is delayed, so that the passenger protection function is sufficient. It is also pointed out that there are fears that cannot be exhibited.

れ得ない。As one measure for avoiding the above-mentioned various inconveniences, it has been proposed to mold the pillar garnish 30 from a material having excellent flexibility and toughness such as TPO (olefin thermoplastic elastomer). There is. However, since the TPO is expensive, the material cost increases, and the problem of increasing the cost cannot be solved.

連設支持部５８は破断しないようになっている。Further, as shown in FIG. 3, the continuous support portion 58 has a concave groove 62 having a semicircular cross section with a radius R.
Is a portion that is appropriately thinned by extending along the second boundary portion S2 in the boundary portion S, and extends in the longitudinal direction of the pillar main body 32 (direction substantially orthogonal to the deformation direction of the pressing portion 42). Existence Here, assuming that the thickness W of the second wall portion 48 is about 2 mm, the maximum depth W1 of the recessed groove 62 is about 0.8 mm, so that the continuous support portion 58 is substantially formed. The thickness W2 is about 1.2 mm. The concave groove 62 forming the continuous support portion 58 has a semicircular shape, and stress is less likely to be concentrated, and the extending direction of the continuous support portion 58 intersects the deformation direction of the pressing portion 42. Due to various conditions such as the above, even if the ruptured portions 56, 56 are ruptured due to the pressing force of the airbag supporting member 14 being applied to the pressing portion 42 of the pillar main body 32, the continuous support portion 58 is not broken. ing.

変形が可能となる。Moreover, the continuous support portion 58 has the concave groove 6
Since the wall thickness is set small by forming 2, the support base that functions as a so-called integral hinge after the completion of the breakage at the planned breakage portions 56, 56 and is firmly fixed to the front pillar 16 by the clip 36 is formed. The pillar main body 32 is allowed to easily change its posture with respect to the portion 34. However, the concave groove 62 is formed along the second boundary S2.
It is not indispensable to reduce the thickness of the continuous support portion 58 by providing the above. That is, when the breakage at the breakable portions 56, 56 is completed, the pressing portion 4 against the support base portion 34 is pressed.
The degree of freedom of deformation of No. 2 is significantly increased, and the pressing portion 42 can be easily deformed without reducing the thickness of the continuous support portion 58.
