Abstract: A rotational assembly hub can include a sprocket that is configured to rotate about an axis, where the sprocket can be located on a first side of a driver. Moveable paws can be located on a second side of the driver that is opposite the first side of the driver. The moveable paws can be configured to move from a recessed position within the driver to a protruding position when the driver rotates in a first direction in a first rotational mode and can be configured to remain protruding from the recessed position when rotated in the first direction in a second rotational mode. Other assemblies are also disclosed.

Abstract: A flame- and puncture-resistant composite fabric sheet material suitable for use for example as an upholstery cover over a urethane or other foam seat cushion and the method of producing the fabric sheet material. The fabric sheet material comprises a thermoplastic polymer layer, such as a vinyl layer, optionally top coated with an abrasion-resistant layer and which thermoplastic layer is bonded to a synthetic fiber, non-woven layer which layer has been needle punched through a metal foil material and a fiberglass scrim layer. The method includes needle punching a synthetic fibrous sheet material through adjacent layers of a metal foil material and a fiberglass sheet, such as aluminum, and extruding a molten vinyl film onto the fibers of the non-woven layer and optionally topcoating the vinyl film to provide a composite sheet material having high flame and puncture resistance.
