  • Patent number: 10112509
    Abstract: The child vehicle capsule is a device that protects infants from impact injuries during unfortunate events. The child vehicle capsule comprises a shell, an impact layer, a comfort layer, and a ventilation system. The shell is an impact resistant enclosure that is absorb the impact energy. The impact layer is a structure that absorbs impact energy by permanently deforming during an unfortunate event. The comfort layer is a viscoelastic structure that: 1) absorbs a portion of the impact energy; 2) that reduces damage caused by the impact force by distributing the impact energy over a time period greater than the initial impact; and 3) that returns to its relaxed shape once the impact forces have been dissipated. The ventilation system manages airflow through the child vehicle capsule to maintain the comfort of the infant.

  • Patent number: 10059682
    Abstract: A method for preparing asymmetric 3,4?-(hexafluroisopropylidene) dipthalic anhydride (a-6FDA) and asymmetric 3,4?-(methylene)diphthalic anhydride (a-MDPA) from asymmetric 2,3,3?,4?-benzophenone dianhydride (a-BTDA). First, a-BTDA is converted to its corresponding N-alkyl or N-phenyl bisimides by reacting with either methylamine or aniline. The sequential addition of two trifluoromethyl (CF3) groups to the carbonyl unit of a-BTDA produce the corresponding bisimides of asymmetric 6FDA, which is hydrolyzed to the asymmetric 6F-tetracarboxylic acid followed by cyclodehydration to obtain asymmetric 6F-dianhydride (a-6FDA). Separately, the carbonyl unit of bisimides of a-BTDA is reduced to a methylene unit to afford the corresponding bisimides of asymmetric 3,4?-(methylene)diphthalic anhydride, which is hydrolyzed to the asymmetric methylene tetracarboxylic acid followed by cyclodehydration to obtain 3,4?-(methylene)diphthalic anhydride (a-MDPA).

  • Patent number: 9487117
    Abstract: A method for producing a cushion element for a vehicle seat, in which a component suitable for forming a three-dimensional separation zone is inserted in a tool, subsequently at least one first foamable mass is introduced into a first space of the tool. On foaming the mass, the component forms a three-dimensional separating element between a first foamed cushion region and a further space within the tool. The component is pressed against a counter-support in the tool during the forming to give a three-dimensional separating element. A suitable tool comprises an upper tool, a lower tool and a counter support for contacting a component taking on a three-dimensional shape. By introducing the three-dimensional mouldable shape into the tool and the subsequent forming thereof to give a three-dimensional separating element, complex formed regions with differing properties, in particular, differing degrees of hardness can be economically generated in a foamed cushion element.

    Abstract: A loose fill packing media that can be used to protect packed items from heat and flame or to contain combustion and heat generated by a packed item comprises a plurality of foam cores formed from a cured thermoset resin coated with a layer of an intumescent material. The foam may be formed by mixing a thermoset resin with micro-balloons and a heat absorbing phase change material, adding a catalyst and shaping the mixture into pellets, curing the shaped pellets and then coating the pellets with the intumescent material. The pellets flow freely at room temperature to facilitate pouring into a box around a package to be protected. If the temperature becomes sufficiently elevated, the intumescent material foams and then chars holding the pellets together. The layer of pellets significantly impedes heat transfer to or from the package surrounded by the pellets.
