Abstract: Materials with exceptional shock attenuating properties are chemically bonded ceramics having densities that range from 30 to 160 lb/cubic foot (0.48 to 2.56 g/cc) and porosities of 20% to 80%. The materials are chemically bonded ceramic composites based on Portland cement, silica fume, various hollow fillers, and may include a dispersing agent, any of a variety of fibers and water.

Abstract: A generant cartridge for incorporation into an airbag inflation module, is produced by shrink wrapping a plastic envelope around gas generant pellets or wafers thereby completely encapsulating the gas generant in a hermetically sealed envelope. The gas generant cartridge may be prepared at one location and brought to an assembly line located at another location. As a result, the assembly of the generant into the module inflator is simplified. The gas generant may be shrink wrapped with an entire filter assembly or with only a portion of the filter assembly and then inserted into an inflator. A booster charge for rapid ignition of the gas generant may also be inserted in the cartridge.

Abstract: A cell or battery which is environmentally benign and which has an electrolyte containing a solution of an alkali metal chlorite or hypochlorite, an anode of Mg or Al and an inert cathode.

Abstract: An autoignition charge for pyrotechnic automotive airbag in inflation devices is provided in the form of a foil of a synthetic polymer or of a metal, having an adhesive on one surface of the foil and an autoignition material on the opposite surface of the foil. Pieces of foil are readily attached to inflator housings at any suitable location and are secured to the housing by the adhesive on one surface of the foil.

Abstract: The actuation of autoignition material in an airbag inflation device is facilitated by providing ports in the module can or housing of the airbag inflation device, and filling the ports with plugs of a fusible, low-melting material, so that when exposed to bonfire conditions, the plugs melt and the ports provide access to the autoignition material.

Abstract: An automotive airbag module housing contains an inflator and a cushion to be inflated. When excessive pressure develops in the module housing, it is relieved through ports in the module housing. The ports are covered with a thin membrane or foil which ruptures before the excessive pressure can damage the airbag cushion during deployment, thereby relieving the pressure in the module housing and in the airbag and avoiding injury to the occupant of the automotive vehicle. The present invention is applicable to any airbag module in which an inflator is completely enclosed within the module housing. It is particularly applicable to passenger side airbag modules.

Abstract: A knee bag cushion is attached to a bolster panel or cushion cover by providing channels on an inner face of the bolster panel and providing retention rods on the outside of the knee bag cushion. The rods are attached to the cushion by passing through loops sewed to the cushion. The retention rods are assembled to the channels by sliding or snapping in the cushion with the rods into the channels on the bolster panel.

Abstract: An undeployed air bag and inflator are wrapped in a soft cloth package. At the time the air bag is inflated, a seam in the cloth ruptures and a portion of the package unfolds to form a guide for the deploying air bag. The package also includes means to secure it to a portion of a vehicle such as a seat back.

Abstract: A valve is provided in an automotive airbag module housing to relieve any excessive pressure in the module housing as may occur during deployment of an airbag. The valve is formed entirely from material in the housing by punching out openings in the housing material. The invention is applicable to airbag inflating devices in which the inflator is enclosed entirely within the module housing and is particularly useful in passenger side airbag inflation devices.

Abstract: An automotive passenger airbag module is assembled by securing two endcaps to a chute or housing. The endcaps have tabs which engage channels in the sidewalls of the housing and may be secured by staking portions of the channels to hold the tabs fast during deployment of the airbag.

Abstract: In a passenger side air bag module assembly, a reaction can is attached and correctly positioned with reference to a module cover or chute by providing a flange on the can with apertures into which protruberences on the module cover may be inserted, thereby joining the can to the cover without the use of screws or rivets or welding.

Abstract: A process for converting sheet stock into a seamless outer shell for a toroidal shaped hybrid inflator for air bag inflation systems. In the process a seamless toroidal shaped shell is fabricated from sheet stock by a sequence of process steps comprising first drawing the sheet into a cup shaped blank, with curved transitions between the bottom wall and the sidewall, and then shaping the open end of the cup to the desired toroidal shape while simultaneously thickening the areas adjacent to the perimeter of the open end of the cup and finally removing the central portion of the bottom of the cup--thereby producing the desired shell.

Abstract: An elongated tubular hybrid gas generator for the inflation of air bags in which the ratio of length to diameter is at least ten. The device may be substituted for a structural element in a motor vehicle, e.g. a steering column or a beam in a door panel with consequent savings in weight and size.

Abstract: In an air bag inflation system, the present invention reduces the pressure at which gas flow is initiated from a stored gas inflator into an air bag to be inflated. In many air bag inflation systems gas flow normally begins following rupture of a diaphragm due to a pressure differential. In the present system this differential is reduced.

Abstract: A snow chain for a motor vehicle tire which consists of a pair of side cables, a plurality of cross cables between the pair of side cables and connected to the side cables by connectors. Rotatably disposed grippers on the cross cables. Deformation of the connectors and damage to the tire is prevented by the insertion of a rubber ring on the cross cable between the grippers and the connector. One direction slippage (skid) is prevented by forming a space of "t" between axially disposed protrusions on the grippers disposed on the cross cables and means to join the ends of each of the side cables to one another.

Abstract: A tent frame permits the roof and walls to be separately established, with consequent ease of erection.

Abstract: An electroless gold plating solution comprising a gold(I) complex, a thiosulfate, a sulfite, a pH regulator and an oxidation controller. The electroless gold plating solution uses a novel reducing agent system, the thiosulfate-sulfite-sulfate system. It shows a plating rate and a plating solution stability comparable to those of conventional gold plating solutions containing borohydride, thiourea, hydrazine, and other reducing agents.

Abstract: This invention relates to electroless nickel plating of metals which are normally noncatalytic for electroless nickel initiation. It is especially useful in the electronics industry, including production of electroless nickel/electroless gold tabs or surface mount pads on printed circuit boards, and for use in electroless nickel plating over copper for radiofrequency interference shielding. More particularly, it comprises alkali halide salt solutions of a palladium salt with another Group VIII precious metal salt in an inorganic acid solution for effectively and completely catalyzing the initiation of electroless nickel plating on copper substrates.

Abstract: A pole useful when skating on in line roller skates. A rigid pole with a specially designed tip which is useful when skating on in-line roller skates and which assists a skater to control his speed of forward motion and may be used as a training aid for beginners learning to skate on in-line roller skates.
