  • Publication number: 20130263383
    Abstract: Disclosed is a method of fabricating an automotive seat cover leather. The method includes a preparing process, a tanning process, a neutralizing process, a retanning process, an elastic material adding process, a dyeing/fatliquoring process, and a surface fixing process. After the leather has gone through the tanning process and neutralizing process, the retanning process adds a tanning agent to the leather. The elastic material adding process adds a silicon-based elastic material to induce elasticity in the retanned leather. The dyeing/fatliquoring process adds a dye to the leather in which the elastic material has been added and adds an anion fatliquoring agent to the leather to provide flexibility. The surface fixing process fixes the elastic material, dye, and fatliquoring agent on and in the leather.

  • Patent number: 7674007
    Abstract: A backlight assembly includes a receiving container, lamps, a diffusion plate and a lamp-fixing member. The receiving container includes a bottom plate and sidewalls together providing a receiving space. The lamps are arranged substantially parallel to each other on the bottom plate. The diffusion plate is disposed over the lamps. The lamp-fixing member includes a body portion extending substantially perpendicular to the lamps, a buffer protruding upwardly from the body portion, a diffusion plate supporting portion protruding from the buffer to support the diffusion plate and a lamp-fixing portion formed at the body portion to fix the lamps. Therefore, the buffer having elasticity is formed at an area at which the diffusion plate supporting portion is formed, so that rubbing between the diffusion plate and the diffusion plate supporting portion may be reduced.
