Abstract
Included are a first board and a second board that include hard polyurethane foam layers and formed respectively in spaces sandwiched between pairs of thin plates, and a coupling member having a porous structure where a recessed groove is formed, parts of the coupling member being arranged in the spaces. The hard polyurethane foam layers are also formed in gaps between the thin plates and the coupling member to join the boards to the coupling member. Consequently, the step of molding the first board can mold, join, and integrate the boards, and mold a bendable, lightweight, and very strong vehicle interior board.
Claims5
A vehicle interior board comprising:
- a first board and a second board each including a pair of thin plates and a hard polyurethane foam layer formed in a space between the thin plates;
- and
- a coupling member configured to couple the first board and the second board, wherein
- the coupling member includes a porous structure having a recessed groove formed in at least one main surface thereof,
- a part of an area on one end side of the coupling member with respect to the recessed groove is arranged in the space of the first board, and joined to the first board while a part of an area on the other end side opposite to the one end side with respect to the recessed groove is arranged in the space of the second board, and joined to the second board, and
- the hard polyurethane foam layers are also formed in gaps between the thin plates and the coupling member to join the first board and the second board to the coupling member;
- wherein an injection hole penetrating from the least one main surface opposed to the thin plate through to an opposing main surface of the coupling member is formed in a portion of the coupling member, the portion being sandwiched between the thin plates, and
- the hard polyurethane foam layer being also formed in the injection hole.
