Patent number: 6328334Abstract: A side airbag to be installed around a window of an automotive vehicle to protect a vehicle occupant from impact in a side collision. The side airbag comprises two base cloths which are joined with each other by hollow weave through a linear joining portion which defines a profile of a hollow section. The linear joining portion includes a first straight linear segment part parallel with warp yarns of the base cloths, and a second straight linear segment part parallel with weft yarns of the base cloths. The first and second straight linear segment parts are connected with each other. The linear joining portion includes a step-like section constituted of at least one first straight linear segment part and at least one second straight linear segment part which are connected to each other Additionally, heat-resistant elastomer is coated on the two base cloths including the linear joining portion.Type: GrantFiled: September 29, 2000Date of Patent: December 11, 2001Assignee: Nihon Plast Co., Ltd.Inventor: Tadao Kanuma

Patent number: 4623011Abstract: A tire-reinforcing dip cord composed of nylon 6 and/or nylon 66 fiber is described. The dip cord has (1) a strength at break of at least 8.2 g/d, (2) an elongation of at least 18% under a load of 8 g/d, (3) a gradient not larger than 0.75 in the load-elongation curve immediately before break, and (4) a cord diameter variation ratio (D/D.sub.o) (D=cord diameter under a load of 450 g and D.sub.o =cord diameter under no load) not larger than 0.65. The dip cord is prepared by treating a nylon 6 and/or nylon 66 cord yarn with an adhesive wherein at least one of the following processes (i) and (ii) is employed: (i) the adhesive treatment is carried out under elongation of at least 3%, and (ii) as the adhesive, a liquid mixture of a resorcinol/formaldehyde (R/F) condensate and a rubber latex is used, in which at least 20 wt. % of the condensate has a R/F molar ratio of 1/1.9-1/1.Type: GrantFiled: December 21, 1983Date of Patent: November 18, 1986Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventor: Tadao Kanuma
