    Abstract: Cool burning hydrate fuels are provided for gas generant compositions for automotive inflatable restraint systems. The cool burning hydrate fuel is a compound comprising carbon, hydrogen, oxygen, a transition metal, and optionally nitrogen. The cool burning hydrate fuel is a transition metal salt of an organic compound or transition metal complex salt having (i) at least one functional group selected from the group consisting of: amide, imide, hydroxyl, carboxylic acid, and combinations thereof, (ii) an oxygen-to-carbon mole ratio of greater than or equal to about 0.5, (iii) at least one-half a water molecule of hydration, and (iv) an exothermic heat of formation of at least about −400 KJ/mole. The fuel may have a water release temperature of ≥about 140° C. The cool burning hydrate fuel may be one or more of copper cyanurate dihydrate, a copper melamine oxalate dihydrate, and a copper malonate hydrate.

    Abstract: An airbag device is adapted to be installed in a vehicle for protecting an occupant. The airbag device includes a bag-like cushion that inflates and deploys in front of a seat and is adapted to restrain the occupant. In an inflated condition, the airbag cushion includes a main inflating section inflating toward the rear of the vehicle, a pair of lobes protruding toward the rear of the vehicle on both sides of the main inflating section in a vehicle width direction, a pair of secondary inflating sections being provided respectively between the main inflating section and each of the lobes in the vehicle width direction and inflating toward the rear of the vehicle, and a pair of tethers are symmetrically attached and tensioned inside the cushion for preventing the protruded lobes from swinging around the main inflating section of the cushion.

    Abstract: Airbag covers having emblems and related methods for coupling emblem elements to airbag covers. In some implementations, a fastening member coupled to an emblem element may be inserted through an opening formed within an airbag cover. The emblem element may be secured to the airbag cover by reshaping at least a portion of the fastening member using a LASER welding process.

    Abstract: Airbag covers and related airbag modules designed with weakened portions configured to specifically accommodate emblems. In some embodiments, an airbag cover may comprise an emblem and a tear seam or another weakened portion extending through and/or adjacent to the emblem to create an asymmetrical split such that, following deployment and rupturing of the tear seam, the airbag cover is configured to form first and second airbag cover pieces, wherein a greater number and/or weight of the emblem is on the first airbag cover piece than the second airbag cover piece.
