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 bonded to the surface of the base member and a covering bonded to the surface of the three-dimensionally knitted cushion layer. The three-dimensionally knitted cushion layer is made of a double-raschel knitted fabric. The base member includes at least one projection that is formed on the surface of the base member and arranged to be adjacent to the tear line.

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.

Stitch line forming method

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.

Vehicle interior panel and vehicle airbag device

A vehicle interior panel includes a base member including a door portion and a cover member adhered to a surface of the base member by an adhesive layer. The door portion includes an end that is opened by an inflation pressure of an airbag. The end of the door portion forms a base member end together with an end of a base member body of the base member. The adhesive layer has an adhesive force set so that the cover member that covers a portion of the base member body that is adjacent to the door portion is separated from the adjacent portion as the door portion opens when pushed by the inflation pressure of the airbag.

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.

Structure of terminal portion of product with cover

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.

A latitudinal division type assist grip having a sufficient load bearing capacity is provided. The assist grip includes an outer cylinder member, a first divisional body, a second divisional body, and an elastic reinforcement member. A first fitting end portion of the first divisional body and a second fitting end portion of the second divisional body are fitted to each other inside the outer cylinder member. The elastic reinforcement member is interposed between an inner peripheral surface of the outer cylinder member and the first fitting end portion, and presses the first fitting end portion toward the second fitting end portion.

Assist grip

The object of the invention is to provide a method for molding a resin-molded article having an excellent surface appearance without any resin-intrusion part on the front surface of a skin thereof. In the invention, the skin is placed on a part of a inner wall of a mold and then injecting a synthetic resin into a cavity of the mold to effect an integral molding of a resin-molded article having the skin on a part thereof, wherein a mold having a first gate on a first inner wall part located on the part other than the back surface of the skin placed on the inner wall of said mold and a second gate on a second inner wall part which faces the back surface of the skin placed on the inner wall is employed; and wherein the synthetic resin is first injected from said first gate until the tip portion of the synthetic resin comes close to the edge of said skin, and then the synthetic resin is injected from the second gate.
