Abstract: An automobile airbag door includes a base member, a cover member, which is bonded to the surface of the base member, and a tear line, which is formed in the back side of the base member. The tear line is configured to be a starting point of tearing when the base member is pressed by an airbag being deployed and inflated. The cover member includes a three-dimensionally knitted cushion layer. The three-dimensionally knitted cushion layer includes a top-side knitted fabric layer, a back-side knitted fabric layer bonded to the surface of the base member, and a connection layer, which is configured by connecting strands connecting the back-side knitted fabric layer and the top-side knitted fabric layer to each other. The mass per unit area of the back-side knitted fabric layer is set to be in the range from 150 g/m2 to 300 g/m2.

Abstract: While feeding an upholstery member, a sewing needle is reciprocated to form needle receiving holes, and an upper thread is passed through each needle receiving hole, caused to cross a lower thread, and pulled out of the needle receiving hole. The sewing cycle is repeatedly performed to form a stitch, so that stitches form a stitch line in a surface sheet. A direction of a force, which is generated by applying tension to the lower thread and which acts to rotate thread ends of a pair of adjacent stitches in each needle receiving hole about a crossing part of the upper thread and the lower thread, is defined as a rotation direction. The sewing needle is rotated in a direction opposite to the rotation direction to incline a diagonal line of the quadrangular shape forming the cross section relative to the feeding direction of the upholstery member.

Abstract: An instrument panel has a base member and a cover member, which is adhered to the top surface of the base member. A first cleavage groove serving as a start point of rupture of the base member caused by inflation pressure of an airbag is formed in the back surface of the base member. The cover member is configured by a ground fabric layer, a cover layer adhered to the top surface of the ground fabric layer, and a cushion layer adhered to the back surface of the ground fabric layer. The cushion layer is formed of a knitted original fabric. A second cleavage groove is formed only in the back surface of the cushion layer out of the layers configuring the cover member in correspondence with the first cleavage groove of the base member.

Abstract: An instrument panel has a substrate and a cover formed by laminating a cushion layer on the back surface of a cover body. A terminal portion of the cushion layer includes a body portion and a peripheral edge portion. The peripheral edge portion is plastically deformed into a compressed state and located around the body portion. The terminal portion of the substrate includes a flat portion and a flange portion. The flange portion surrounds the flat portion in a state of protruding to the top side. The cover is adhered onto the terminal portion of the substrate by adhering the body portion onto the flat portion and adhering the peripheral edge portion onto the flange portion. The peripheral edge portion is adhered onto the flange portion in a state where the peripheral edge portion is folded along the top surface and a side surface of the flange portion.

Abstract: An instrument panel of an automobile includes a base and a covering bonded to a surface of the base. A cleavage groove is formed on the back of the base. When the base is cleaved by inflation pressure of an airbag, the cleavage groove serves as a starting point of the cleavage. The covering is formed by a ground fabric layer made of knitted fabric and a covering layer bonded the surface of the ground fabric layer. The ground fabric layer is formed of an original fabric in which the tensile strength in directions along its surface is anisotropic. The cleavage groove includes a first groove section, which is cleaved first. The covering is oriented with respect to the base such that the direction of the smallest tensile strength of the ground fabric layer matches with a direction perpendicular to the direction in which the first groove section extends.
