摘要:
A gas generator for air bags for use in an air bag system for safely protecting a driver and riders in a vehicle from shock from collisions at low cost, while preventing slag in a gas flowing outside. The gas generator includes a housing (3) formed by a side cylinder (1b) with a plurality of gas exhaust openings (8) the housing being closed at its ends by an upper cap (1a) and a lower cap (2a); an igniting device (16), provided in the housing (3) at a center portion thereof; gas generating agents (6), provided in the housing (3) at a location radially outside of the igniting device (16), to be burnt to generate gas; a cooling/filtering member (7) provided in the housing (3) at a location radially outside of the gas generating agents (6) to enclose the gas generating agents and extending from the side of the upper cap (1a) to the side of the lower cap (2a); and an annular projection (50) for preventing the gas generated by the burning of the gas generating agents (6) from flowing toward an end portion of the cooling/filtering member (7). The annular projection (50) is integrally formed on at least one of the upper cap (1a) and the lower cap (2a) so as to abut with an inner peripheral surface of the cooling/filtering member (7).

摘要:
The present invention provides a gas generator for expanding and inflating a driver's seat airbag. The gas generator comprises two ignitor device 8, 9 for burning gas generants 7 packed in combustion chambers 3, 4, and enhancer device 10, 11 for allowing the flames from the ignitor device 8, 9 to be propagated circumferentially and radially of a housing 1.
摘要:
It is an object of the present invention to provide a gas generator suitable for an organic-compound gas generating agent and excellent in heat resistance, pressure resistance, and sealing. In the gas generator, a housing (4) is formed by joining an iron- or steel-made upper lid (2), consisting of a top plate (2a) and a side cylinder (1a) extending downward from an entire circumferential edge thereof and provided with many gas discharge holes (8) with an iron- or steel-made lower lid (3), consisting of a bottom plate (3f), side cylinder (1b) extending upward from an entire circumferential edge thereof, and an ignitor holding portion (3a) formed integrally with the bottom plate (3f) and for fixing by caulking an ignitor (30). In the housing (4), the ignitor (30) and a gas generating agent (6) are arranged in the order mentioned from a center thereof.
摘要:
A gas generator for air bags including a housing (3) defined by a side cylinder (1b) having a plurality of gas outflowing holes (10) and an upper cover (1a) and a lower cover (2a) for closing ends of the side cylinder (1b); an igniter (4), a gas generating agent (6) and a cooling filter member (8) disposed in this order in the housing (3) from a center thereof toward a radially outward side thereof; and a metallic foil (11) disposed on an inner wall surface of the side cylinder (1b) to cover the gas outflowing holes (10) from inside. The cooling filter member (8) extends from the upper cover (1a) to the lower cover (2a). The cooling filter member (8) is cylindrical in shape and has a thick walled portion (8a) formed on an outside diameter side on an end axially opposite to the gas outflowing holes (10), and the thick walled portion (8a) is press fitted into an inner surface of the housing (3).
摘要:
A gas generator for slowly inflating an air bag at the early stage of the inflation and then rapidly inflating it or discharge a clean gas evenly around a housing. The gas generator includes a gas generating agent (6) and an squib (8,9) in the housing (1). The squib (9) is disposed eccentrically to the axis (a) of the housing (1). A high temperature gas is generated in a combustion chamber (4) because of the combustion of the gas generating agent (6) ignited by the squib (9). The permeability of the high temperature gas through inner cylindrical member (2) closest to the squib (9) is lower than that through the part other than the inner cylindrical member (2).
摘要:
It is the object of the present invention to provide a gas generator that can provide a controlled expansion and inflation of the airbag with improved reliability. The gas generator D of the present invention is so structured that gas generating agents 7 packed in combustion chambers 3, 4 can be burnt by two ignitors 8, 9 independently of each other, wherein the ignitors 8, 9 electrically ignite ignition agents 26 by use of bridge wires 24 for generating heat by electrifying, and resistance values thereof are differentiated from each other.
摘要:
The present invention relates to a knee protection device for protecting the knees of an occupant when a vehicle collides. The protection device includes a knee protecting member which has a hollow cross-section outer frame composed of a front plate, a load-bearing plate, an upper plate and a lower plate, and a hollow cross-section inner frame integrally formed within the outer frame. The inner frame is integrally formed with the outer frame by connecting adjacent middle portions of the front plate, upper plate, load-bearing plate and lower plate, using plate-shaped ribs. Even if an action point on the load-bearing plate varies according to variation in height of the occupant's knee due to individual difference, impact energy is directly transmitted to the upper and lower plates as well as being dispersed and transmitted through the inner frame to the middle points of the upper, lower and front plates, efficiently received by the four plates constituting the outer frame, and thus the outer frame plastically deforms in a steady manner.
