Abstract

The present invention is to provide a vehicular interior member in which three components can be strongly joined to each other and the weight can be reduced. A vehicular interior member is formed so that first and second components respectively made of thermoplastic resin, and a middle component arranged between the first component and the second component are joined to each other. The first component has a boss projecting to the second component side. The middle component has a through hole through which the boss is inserted. The second component has a through hole through which the boss is inserted, and a fitting portion projecting to the middle component side, the fitting portion being fitted to an edge portion of the through hole. The boss and the second component are welded to each other.

First claim

What is claimed is:

1. A vehicular interior member comprising:
a first component and a second component respectively made of thermoplastic resin, and a middle component arranged between the first component and the second component, wherein the first component, the second component, and the middle component comprise flat plate portions which are joined substantially parallel to each other, wherein:
the first component has a first projection portion projecting to a second component side thereof,
the middle component has a first through hole through which the first projection portion is inserted,
the second component has:
a second through hole through which the first projection portion is inserted, and
an annular fitting portion surrounding the second through hole that projects to a first component side of the second component, and is inserted into and penetrates the first through hole of the middle component with the first projection portion extending therethrough, wherein a side surface of the fitting portion interlockably engages with an engagement element extending from an edge portion of the first through hole, and
the first projection portion is welded to the second component on a side thereof opposite the first component side.

2. The vehicular interior member according to claim 1 , wherein
the fitting portion is formed in a tubular shape.

3. The vehicular interior member according to claim 1 , wherein
the first projection portion is a boss.

4. The vehicular interior member according to claim 1 , wherein:
the first component has a wall portion provided around a periphery of the first projection portion, the wall portion extending from a side facing the middle component to the second component side, and
the fitting portion is arranged between the first projection portion and the wall portion.

5. The vehicular interior member according to claim 4 , wherein
the wall portion is abutted with the middle component.

6. The vehicular interior member according to claim 4 , further comprising:
a rib coupled to a lower portion of the first projection portion and a lower portion of the wall portion, respectively.

7. The vehicular interior member according to claim 4 , wherein
the wall portion is an annular standing wall.

8. The vehicular interior member according to claim 1 , wherein
the first component has a wall portion that is provided around a periphery of the first projection portion and that extends to the second component side, and
the wall portion is arranged at a position that does not overlap the fitting portion in a direction perpendicular to a projecting direction of the first projection portion.

9. The vehicular interior member according to claim 8 , wherein
a thickness of the fitting portion is greater than a thickness of the wall portion.

10. The vehicular interior member according to claim 1 , wherein
the vehicular interior member is a door lining of a vehicle.

11. A vehicular interior member comprising:
a first component and a second component respectively made of thermoplastic resin, and a middle component arranged between the first component and the second component, wherein the first component, the second component, and the middle component comprise flat plate portions which are joined substantially parallel to each other, wherein:
the first component has a first projection portion projecting to a second component side thereof,
the middle component has a first through hole through which the first projection portion is inserted,
the second component has:
a second through hole through which the first projection portion is inserted, and
an annular fitting portion surrounding the second through hole that projects to a first component side of the second component, and is inserted into and penetrates the first through hole of the middle component with the first projection portion extending therethrough,
the first projection portion is welded to the second component on a side thereof opposite the first component side,
a first slit portion is provided on a side surface of the fitting portion, and
a claw portion extends from an edge portion of the first through hole, wherein the claw portion interlockably engages with the first slit portion.

12. The vehicular interior member according to claim 11 , wherein:
plural second slit portions are provided in the edge portion of the first through hole, and
in the edge portion of the first through hole, a portion between the plural second slit portions serves as the claw portion.

13. The vehicular interior member according to claim 11 , wherein
an inclination portion inclined toward the center of the first through hole is provided in the edge portion of the first through hole.

14. A method for manufacturing a vehicular interior member including a first component and a second component respectively made of thermoplastic resin, and a middle component arranged between the first component and the second component, wherein the first component, the second component, and the middle component comprise flat plate portions which are joined substantially parallel to each other, comprising:
providing the first component with a first projection portion projecting to a second component side thereof,
providing the middle component with a first through hole,
providing the second component with a second through hole and an annular fitting portion surrounding the second through hole that projects to a first component side of the second component,
inserting the first projection portion into the first through hole of the middle component,
inserting the first projection portion into the second through hole of the second component,
inserting the fitting portion into the first through hole of the middle component to penetrate the first through hole with the first projection portion extending therethrough, wherein a side surface of the fitting portion interlockably engages with an engagement element extending from an edge portion of the first through hole, and
welding a portion of the first projecting portion that projects from the second through hole of the second component to the second component on a side thereof opposite the first component side to join the first component and the second component by welding.
