Abstract:
1. A child restraint comprising a juvenile vehicle seat an energy-dissipation system coupled to the juvenile vehicle seat, the energy-dissipation system comprising a first force dissipater including a first bag formed to include an undivided first air chamber and a first air-discharge port opening into the first air chamber and a first support frame located in the first air chamber and made of a deformable material and configured to support the first bag to maintain at least a predetermined volume of air in the first air chamber until the first bag and the first support frame are deformed when exposed to an external impact force, wherein the first air-discharge port is configured to provide means for discharging air from the first air chamber to the surroundings at a metered rate when the first bag is exposed to the external impact force so that the first force dissipater absorbs external energy associated with the external impact force to minimize g-loads experienced by a child seated in the juvenile vehicle seat, and wherein the first support frame includes a first shock absorber located in the first air chamber and arranged to lie in spaced-apart relation to the first air-discharge port and between and in confronting relation to two opposing walls included in the first bag and arranged to locate the first air chamber therebetween and wherein the first shock absorber includes a deformable casing formed to include an interior chamber filled with a fluid medium maintained at a predetermined pressure to allow deformation of the deformable casing in response to application of a force to the deformable casing owing to relative movement of the two opposing walls included in the first bag.
