Abstract: A flexible back support for use in seats such as automobile seats or office chairs.

Abstract: A flexible back support for use in seats such as automobile seats or office chairs, includes a central body portion with outwardly extending support fingers such that an arch having a variable apex is formed when the back support is subtended longitudinally. The longitudinal location of an apex and the shape of the arch formed on the back support changes responsively to a load imposed by a person's back. Noise, galling, wear and rough movement between moving parts of the flexible back support are reduced by the coefficient of friction reduction method of the present invention.

Abstract: A starting and reinforcing tab or plate for fasteners, especially suitable in reference to automobile bodies and trim, comprising a thin walled support plate having a plurality of upper surface upsets or indentations and an adhesive lower surface with a release sheet for activation and exposure of the mastic, and together providing a reinforcing element selectively locatable to steady a drill point for selected penetration of the reinforcing plate and the material to which the tab is applied and enhancing the grip of fasteners drawing the intermediate elements into a compression relationship.
