  • Patent number: 8851507
    Abstract: An airbag, or inflatable cushion assembly, can include an inflatable cushion and a throat liner. The throat liner can be coupled to an interior surface of the inflatable cushion at one or more coupling sites. The one or more coupling sites can include one or more panels that can be coupled to at least a portion of both of the inflatable cushion and the throat liner. The one or more panels can be configured to control or inhibit egress of an inflation gas at the one or more coupling sites.
    Type: Grant
    Filed: March 15, 2013
    Date of Patent: October 7, 2014
    Assignee: Autoliv ASP, Inc.
    Inventors: John D. Kemp, G. Doyle Obray, Kazuki Fujiwara, Roger Rickenbach

  • Patent number: 6245290
    Abstract: A high-tensile-strength steel having excellent toughness throughout its thickness, excellent properties at welded joints, and a tensile strength (TS) of at least about 900 MPa (130 ksi), and a method for making such steel, are provided. Steels according to this invention preferably have the following composition based on % by weight: carbon (C): 0.02% to 0.1%; silicon (Si): not greater than 0.6%; manganese (Mn): 0.2% to 2.5%; nickel (Ni): 0.2% to 1.2%; niobium (Nb): 0.01% to 0.1%; titanium (Ti): 0.005% to 0.03%; aluminum (Al): not greater than 0.1%; nitrogen (N): 0.001% to 0.006%; copper (Cu): 0% to 0.6%; chromium (Cr): 0% to 0.8%; molybdenum (Mo): 0% to 0.6%; vanadium (V): 0% to 0.1%; boron (B): 0% to 0.0025%; and calcium (Ca): 0% to 0.006%. The value of Vs as defined by Vs=C+(Mn/5)+5P−(Ni/10)−(Mo/15)+(Cu/10) is 0.15 to 0.42. P and S among impurities are contained in an amount of not greater than 0.015% and not greater than 0.003%, respectively.

  • Patent number: 6183573
    Abstract: High-tensile-strength steel having excellent arrestability and a TS of not less than 900 MPa, as well as a method of manufacturing the same. The steel of the invention has the following composition (% by weight): C: 0.02% to 0.1%; Si: not greater than 0.6%; Mn: 0.2% to 2.5%; Ni: greater than 1.2% but not greater than 2.5%; Nb: 0.01% to 0.1%; Ti: 0.005% to 0.03%; N: 0.001% to 0.006%; Al: not greater than 0.1%; and optional elements. Ceq of the B-free steel is 0.53-0.7%, and Ceq of the B-bearing steel is 0.4-0.58%. The microstructure of the steel may be a mixed structure of martensite (M) and lower bainite (LB) occupying at least 90 vol. % in the microstructure, LB occupying at least 2 vol. % in the mixed structure, and the aspect ratio of prior austenite grains is not less than 3.
