<p>PURPOSE:To provide a pad for an air bag device where the core layer is separately formed, the insert forming is unnecessary, a manufacturing man-hour can be greatly reduced, and an injection forming die can be simple. CONSTITUTION:In a constitution where a pad covers the upper surface of an air bag device 11, and unfolding groove parts 19 to unfold the upper wall part 17 by the rupture of the pad body 13 when an air bag 15 is swollen are continuously provided, the pad body 13 is composed of the thermo-plastic elastomer (TPE) having the low temperature tensile strength TB (-35 deg.C): 200-500kgf/cm<2>, and the single layer is formed so that the average wall thickness of the upper wall part may be 2.5-6.0mm. The residual wall thickness (t) of the unfolding groove part 19 is 0.3-1.5mm, and the groove angle alpha on the rear side is 30-90 deg..</p> |
