Abstract:
An inflatable restraining band for vehicle safety systems which is formed from an extruded seamless plastic tube having fiber reinforcement extending longitudinally thereof.
Abstract:
Switch in seat belt buckle which operates upon insertion of tongue of buckle and operates under magnetic force when tongue is not inserted in buckle to give signal indication or interlock with ignition.
Abstract:
A vehicle safety system is provided which comprises a seat belt having an inflatable section which is normally maintained in an uninflated state and adapted to be positioned about a wearer when the wearer is seated in a seat within the vehicle, sensing means actuatable in response to the occurrence of a preselected condition of the vehicle, and inflating means responsive to actuation of the sensing means and capable of inflating the inflatable section prior to any substantial forward motion of the seat belt wearer relative to his seat as a result of the preselected condition.
Abstract:
An electric circuit assembly for transmitting a signal to initiate the inflation of a gas bag safety assembly in an automobile when the vehicle is involved in a collision. The circuit assembly is provided with diagnostic means to allow the driver to monitor the readiness of the circuit for operation and detect any malfunction in the assembly. Upon start-up of the vehicle, indicator means in the circuit assembly, in the form of a pair of warning lamps, indicates whether the circuit assembly is operating normally. One of the lamps is normally lit for a short period after the ignition switch is closed. The other lamp only becomes lit when the first lamp fails to light. The circuit is formed so as to operate properly despite the failure of various of its components.
Abstract:
This invention relates to the procedure of redundancy, without operational compromise, in the supply of generated gas from a pyrotechnic device to an inflatible bag assembly.
Abstract:
A method and apparatus for filling motor vehicle gas bags. A gas-filled cylinder is provided with an inlet pressure sensitive rupture disc and a dislodgeable outlet plug. The inlet disc is in communication with a combustible material. The material is fired, yielding a gaseous product. The outlet plug is dislodged before the rupture of the inlet disc at least substantially emptying the cylinder before said disc ruptures. The liberated gas flows to a diffuser, about which a motor vehicle gas bag or bags are disposed, whereby the filling of gas bag (or bags) is delayed, it being filled first with gas filling the cylinder and then with gas generated from the combustible material when the disc ruptures.
Abstract:
Apparatus for transmitting an electrical current from a power supply to a gas source during a time interval which varies in direct proportion to the ambient temperature within the portion of a vehicle in which the apparatus is disposed. A portion of the gas is released from the gas source upon receipt of the electrical pulse. Another portion of the gas is released from the gas source independently of the pulse. The released gas passes into a bag, which inflates during a time interval independent of the ambient temperature, thereby serving to protect occupants or other mobile objects within the vehicle.
Abstract:
A circuit for firing the gas generating system of an inflatable safety bag device includes a capacitor which is charged from the battery at such time as the ignition switch is closed. A light emitter is connected to the capacitor so as to be energized during the charging of the capacitor. A sensor detects output from this light and controls the energization of a second light emitter. In the event the first light emitter emits light following the closure of the ignition switch, indicating proper operation of the circuitry, the second light emitter will be deenergized. Fiber optic bundles lead from both of the light emitters to a visual indicator assembly mounted on the dashboard of the vehicle. An alternate embodiment of the invention employs only a single light emitter diode which is normally energized and is deenergized in the event an inductive sensing means does not detect the proper operation of the charging circuitry.
