  • Patent number: 8733788
    Abstract: A method of forming a fabric for an air-bag, the method comprising providing a plurality of yarns, each yarn being formed from a plurality of individual fibres; applying an activatable additive or coating to each yarn, the additive or coating initially not being activated and wherein, prior to activation, the additive or coating presents little or no impedance to the relative movement of the fibres within the yarn and, following activation, the additive or coating binds fibres within the yarn to one another to prevent or hinder relative movement of the fibres in the yarn with respect to one another; and passing the yarns through an activation zone including a compressing component which applies a compressive force to the yarns, the additive or coating being activated as the yarns pass through the activation zone so that the yarns each have a substantially flat configuration.

  • Patent number: 8720946
    Abstract: A gas generator has two pyrotechnic charges in two chambers having openings for gas outlet to the outside. Only the first chamber is provided with an igniter for first charge. The chambers are separated by a third wall with a through hole for permanent gas communication, sealed in an initial state by a cap. The cap is configured to be broken under the pressure of the combustion gases from first charge to keep the hole opened permanently and allow the combustion gases from the first charge to go via the hole kept permanently opened from a first chamber to a second chamber, where these gases induce the combustion of charge.
