Vehicle upholstery member having air bag door, and method and device for producing the same

A method of producing a vehicle upholstery member having an air bag door equipped with a fabricated skin, comprising the following steps (a) to (c):

• (a) partially or entirely bending the skin with its back surfaced convexed, wherein the skin is mounted on a substrate and pressed with a protrusion arranged in the substrate for bending the skin with its back surfaced convexed and the protrusion is moved up and pressed upward against the skin;
• (b) forming a break-scheduled line that is not so deep as to reach a front surface of the skin with a cutting blade;
• and
• (c) measuring a depth of the break-scheduled line or a thickness of a remaining portion of the skin where the break-scheduled line is formed with an incision of the break-scheduled line opened.

A device for producing a vehicle upholstery member having an air bag door equipped with a fabricated skin, comprising:

• a support base for substantially flatly mounting the skin thereon equipped with a protrusion for upward pressing the skin;
• a cutting blade for forming a break-scheduled line in the skin;
• and
• measuring means for measuring a depth of the break-scheduled line or a thickness of a remaining portion of the skin where the break-scheduled line is formed,
• wherein the protrusion is moved up to a given height and pressed upward against the skin, and
• wherein the measuring means is used to measure the depth of the break-scheduled line or the thickness of the remaining portion of the skin where the break-scheduled line is formed, with an incision of the break-scheduled line opened.
