Front pillar structure
A front pillar structure is provided with a pillar frame component that forms part of a front pillar, and with a pillar garnish that forms part of the front pillar, and that has a surface covering portion that extends substantially in the vehicle vertical direction and covers the pillar frame component from the vehicle cabin inner side, and an elastic body that is joined to a wall surface facing the pillar frame component of the surface covering portion, and that firmly grips inside itself the vehicle cabin inner-side flange portions of the first component and the second component.
1. A front pillar structure, comprising:
a pillar frame component that forms part of a front pillar, and that is formed with a closed cross-sectional configuration formed from a first component having a vehicle cabin outer-side flange portion and a vehicle cabin inner-side flange portion and extending substantially in a vehicle vertical direction, and a second component having a vehicle cabin outer-side flange portion and a vehicle cabin inner-side flange portion and extending substantially in the vehicle vertical direction, the respective vehicle cabin outer-side flange portions and the respective vehicle cabin inner-side flange portions being overlaid and joined together; and
a pillar garnish that forms a part of the front pillar, and that has:
a surface covering portion that extends substantially in the vehicle vertical direction and covers the pillar frame component from the vehicle cabin inner side; and
an elastic body that is joined to a wall surface facing the pillar frame component of the surface covering portion, the elastic body firmly gripping the vehicle cabin inner-side flange portion of at least one of the first component or the second component.
2. The front pillar structure according to claim 1 , wherein, in a planar cross-sectional view, the vehicle cabin inner-side flange portion firmly gripped by an interior of the elastic body protrudes towards an upper body of a vehicle occupant seated at a seat.
3. The front pillar structure according to claim 1 , wherein a distal end portion of the vehicle cabin inner-side flange portion firmly gripped by an interior of the elastic body has a portion that is bent substantially at a right angle in a planar cross-sectional view.
4. The front pillar structure according to claim 3 , wherein the distal end portion of the vehicle cabin inner-side flange portion firmly gripped by the interior of the elastic body and the bent portion form an L-shape embedded inside the elastic body.
5. The front pillar structure according to claim 1 , wherein the surface covering portion is formed substantially in a U-shape that is open towards the vehicle cabin outer side in a planar cross-sectional view.
6. The front pillar structure according to claim 5 , wherein an outer surface of the elastic body has a U-shape corresponding to the U-shape of the surface covering portion.
7. The front pillar structure according to claim 1 , wherein a notch is formed in the elastic body, and the vehicle cabin inner-side flange portion of at least one of the first component or the second component is inserted into the notch portion.
8. The front pillar structure according to claim 1 , wherein
the closed cross-sectional configuration of the pillar frame component comprises a closed cross-sectional shape,
the vehicle cabin outer-side flange portions of the first and second components are overlaid and joined together at a first location outside the closed cross-sectional shape, and
the vehicle cabin inner-side flange portions of the first and second components are overlaid and joined together at a second location outside the closed cross-sectional shape.
9. The front pillar structure according to claim 1 , wherein
the vehicle cabin outer-side flange portions of the first and second components are overlaid and welded together, and
the vehicle cabin inner-side flange portions of the first and second components are overlaid and welded together.
10. The front pillar structure according to claim 1 , wherein the surface covering portion covers, without contacting, the vehicle cabin inner-side flange portions and the vehicle cabin outer-side flange portions.
11. The front pillar structure according to claim 1 , wherein
the surface covering portion has an inner surface that faces towards the pillar frame component, and
the elastic body is joined by an adhesive to the inner surface of the surface covering portion.
12. The front pillar structure according to claim 1 , wherein distal end portions of the surface covering portion are bent towards the pillar frame component.
13. The front pillar structure according to claim 1 , wherein the vehicle cabin inner-side flange portions of the first and second components are joined together outside the elastic body.
14. The front pillar structure according to claim 1 , further comprising:
a U-shaped core metal inserted into a notch of the elastic body,
wherein the vehicle cabin inner-side flange portions of the first and second components are inserted into the U-shaped core metal which is inserted into the notch of the elastic body.
