Abstract: An automobile airbag door includes a base member and a cover member. A tear line TL is formed in the back of the base member. When the airbag door is pressed by the airbag, the tear line TL provides a starting point of tearing action. The cover member includes a three-dimensionally knitted cushion layer, which includes a top-side knitted fabric layer, a back-side knitted fabric layer, and a connection layer. The connection layer is configured by connecting yarn, which couples the top-side knitted fabric layer and the back-side knitted fabric layer to each other. The weight per unit length of the connecting yarn is greater than the weight per unit length of the yarn constituting the top-side knitted fabric layer and is greater than the weight per unit length of the yarn constituting the back-side knitted fabric layer.

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: An air bag mounting interior trim that efficiently pressurizes and welds ribs of a retainer and an instrument panel includes: a retainer having a first wall portion disposed at a deployment side of the air bag; and a panel having a second wall portion opposed to the first wall portion, at the deployment side of the first wall portion. The first and second wall portions each have an inclined face inclined in a pressurizing direction at assembly of the retainer and the panel. The retainer has a first rib protruding along the pressurizing direction from the inclined face of the first wall portion toward the panel side. The panel has a second rib protruding along the pressurizing direction from the inclined face of the second wall portion toward the retainer side. The first and second ribs have weld end faces that face each other in parallel, and that are aligned with the pressurizing direction.

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 automobile airbag door includes a base member, a three-dimensionally knitted inner cushion layer, which is arranged on one side of the base member, and a covering arranged on a side of the inner cushion layer that is opposite to the base member. The base member and the inner cushion layer each have a plurality of cleavage grooves, which serve as starting points of breaking action when the airbag door is pressed by the airbag being deployed and inflated. An outer cushion layer is located between the inner cushion layer and the covering.
