Abstract: An airbag with an inflation gas diffuser comprising an inflator side cloth and an occupant side cloth both of a substantially equal size and a generally circular shape seamed together at outer peripheral portions thereof to form an outer configuration of the airbag. The inflator side cloth has a central opening through which to communicate with an inflator, and an internal cloth of a smaller size enclosed within the airbag to cover the opening. The internal cloth is partially seamed at its outer perimetric portion, to the inflator side cloth so as to form circumferentially alternately seamed portions and non-seamed open portions acting as a control passage for the inflation gas. The internal cloth may be circular, semicircular, dumbbell, polygonal, etc. The seamed portions each may consist of a main straight seam and two curved end seams.

Abstract: An inflatable bag for airbag passive restraints for driver which comprises upper and lower circular base cloths of the same size seamed together at their outer peripheries and lateral regulating means for regulating inflation of the bag in lateral and upward directions and causing downward inflation, which means extends to link between an inner periphery of the lower base cloth and the outer peripheries in a shorter length than the radial distance therebetween, thus forming a sag portion on the lower cloth. When the bag is deployed, the lateral regulating means enables the sag portion to bulge sideways out of a steering wheel to protect a driver. The bag may further include upward restricting means for upward inflation. The lateral and the upward regulating means may be located in a whole circumferential area or within a range of 1/2 to 1/4 the circumference of both cloths.

Abstract: An air bag structure for an automobile is provided in an outlet provided in an instrument panel. The air bag is supported for expansion through the outlet and surface material covers the instrument panel including the outlet and includes stitch-like slits in registry with the outlet to cause the surface material to tear along predetermined lines upon expansion of the air bag.

Abstract: The present invention provides laminate structures of interior finishing material having suitable air permeability and sound absorbing properties.

Abstract: The present invention provides a polyurethane foam interior finishing material having a facing, characterized in that the material comprises a laminate of a thermoplastic synthetic resin facing material and an expanded pad layer, the expanded pad layer comprising a semi-rigid polyurethane foam reinforced with long glass fibers, the long glass fibers being present in the pad layer primarily in the vicinity of the rear side thereof, the finishing material having no core. The invention also provides a process for preparing the material.

Abstract: A process for the production of a porous ceramic mold is described, compsiging adding about 40 to 60 parts by weight of water to 100 parts by weight of a ceramic material, mixing the thus-formed ceramic slurry with about 20 to 40 parts by weight of a hydrophilic urethane prepolymer having a free isocyanate group content of from about 4% to 7% by weight, reacting and foaming the resulting mixture after the introduction thereof into a mold, drying the thus-formed foamed urethane molded article, and combusting very slowly and sintering the dried foamed urethane molded article to produce a porous ceramic molded article.
