PROBLEM TO BE SOLVED: To recover valuable metals by shearing and finely pulverizing an inflator for air bag and separating the included materials in order by means of screening, magnet, burning, etc. SOLUTION: A shearing or cutting operation is executed to the inflater for air bag, and this inflater is scatteringly broken and screened to remove gas generating materials. If necessary, iron metal parts are separated from aluminum parts with the magnet. Successively, the burning is executed in a melting furnace and the temp. is raised to about 927 deg.C to melt the aluminum to be taken out. Since the non-melting remained materials containing iron component are retained in the melting furnace, these materials are recovered. By this method, the valuable metals are recovered from the inflater for air bag and can be reused.

PROBLEM TO BE SOLVED: To obviate a means to be added from outside to a seat of a vehicle by arranging a thermoplastic cover to regulate a weakening tearing-off line in an intermediate part of both vertical edges in parallel to the first and second vertical edges to open an air bag when the air bag expands. SOLUTION: A plastic cover 10 extending in the lengthwise direction when the lengthwise direction is set in the vertical direction, is formed of an extrusion mold of a plate-like seat shape having opposed both vertical edges. One vertical edge of its cover 10 forms a bead 12, and the other vertical edge carries a semicylindrical socket 14, and its bead 12 is fitted in a snap so as to form a surrounding tubular body to the socket 14, and a vertical tearing-off line 22 is also formed between both in parallel to both vertical edges to which a seat is opposed. Therefore, a means to be added from outside to the seat of a vehicle can be obviated.

PROBLEM TO BE SOLVED: To provide a coil filter structure easily installed on a base of a pressure vessel.SOLUTION: In an inflator for an airbag, an inner lid 24 having an igniter, a gas generating agent, a filter 21 and a folding-back part 24a for covering the gas generating agent and abutting on an inner wall of the filter 21, is internally installed in the pressure vessel composed of the base 2b and a diffuser 2a. The filter 21 is constituted of a double layer structure including an inner filter 22 formed in a cylindrical shape by a coil and a wire net-like outer filter 23 fitted to an outer peripheral surface of this inner filter 22 and having a mesh coarser than the inner filter of an outer diameter slightly larger than an inner diameter of the base 2b. When pressing the filter in the base, assembly work is easily executed since the inner filter is pressed in the base without being lifted.
Abstract:
PROBLEM TO BE SOLVED: To provide alkali metal perchlorate-containing gas generant compositions which, upon combustion, produce or result in an improved effluent and related methods for generating an inflation gas for use in an inflatable restraint system.SOLUTION: The alkali metal perchlorate-containing gas generant compositions include at least one alkali metal perchlorate present with a mean particle size in excess of 100 micrometers. Such alkali metal perchlorate-containing gas generant compositions also include or contain a suitable non-azide, organic nitrogen-containing fuel and at least one copper-containing compound selected from the group consisting of basic copper nitrate, cupric oxide, copper diammine dinitrate-ammonium nitrate mixture wherein ammonium nitrate is present in the mixture in a range of about 3 to about 90 wt.%, copper diammine bitetrazole, a copper-nitrate complex resulting from reaction of 5-aminotetrazole with basic copper nitrate and combinations thereof.

PROBLEM TO BE SOLVED: To prevent a retainer disc from easily slipping out in action time and operation time of external force.SOLUTION: In this inflator 1 for an airbag, an igniter 3 and a gas generating agent 7, the retainer disc 10 fitted to an igniter tube 4 and a filter 8 arranged along the sidewall part inner peripheral side of a pressure vessel 2, are internally arranged in the pressure vessel 2 for integrally joining a diffuser 2a and an adapter 2b for holding the igniter tube 4 to a base 2c. The retainer disc 10 has a hollow projecting fitting part 10a having a first fitting surface 10d. The length L3 in the outer peripheral side fitting direction of the fitting part 10a of the retainer disc 10, is shortened more than the fitting length L1 of the first fitting surface 10d of the retainer disc 10. Safety of welding work of the base and the diffuser is improved, and damage done to the airbag can be restrained even in operation of the inflator.
Abstract:
PROBLEM TO BE SOLVED: To prevent rupture of a pressure vessel even if inner pressure is raised when gas is generated.SOLUTION: The inflator 1 for an airbag includes, inside a pressure vessel 2 integrally formed by joining an adapter 2b and a diffuser 2a to a base 2c, at least an igniter 3 supported on the adapter 2b, a gas generation agent 5, and a filter 6 disposed along the inner periphery of a side wall of the pressure vessel 2. The adapter 2b includes a collar part near a joint part Y2 with the base 2c. An outer periphery end of the collar part is chamfered or rounded, and the outer periphery end of the collar part is made to abut on the base. The deformation amount of the base becomes large when the pressure vessel is deformed by rise of the inner pressure, consequently stress concentration occurring on the base is suppressed, and the rupture of the pressure vessel is prevented.
Abstract:
PROBLEM TO BE SOLVED: To provide a low density slurry bridge mixture to be used for an expansion type constraining system. SOLUTION: The low density slurry bridge mixture 34 is constituted so that a zirconium metal, a thermally conductive enhancer such as aluminum metal for example, a potassium perchlorate oxidizing agent and a binder material are contained and the mixture has a drying density of about 45-65% of a theoretical density. The low density slurry bridge mixture 34 is used at a detonating device 10 including a non-grinding header 12 attached in a heave bridge wire 20, and in that case, the detonator is constituted so that the low density slurry bridge mixture 34 wraps a bridge wire 20 and may adhere to it.

Abstract:
PROBLEM TO BE SOLVED: To facilitate appropriate joining of an initiator assembly and an inflator case while reducing the size of an injection molding part in a manufacturing method for an inflator having the initiator assembly. SOLUTION: The manufacturing method comprises the steps of preparing the initiator assembly used for activating the inflator, injection-molding an insertion member with the initiator assembly using insulation material, and joining the initiator assembly with the inflator. The joining step includes folding a part of the inflator adjacent to the insertion member after the injection-molding step. COPYRIGHT: (C)2009,JPO&INPIT
