Description

Logo lighting device of automobile seat cover The present invention relates to a logo light-emitting device provided in an automobile seat cover, and more specifically, to a logo light-emitting device for an automobile seat cover that enhances the visibility and aesthetic appeal of a seat logo (L) formed on the seat cover (C2) without impairing the comfortable seating sensation of the occupant, by comprising a seat perforation hole (10) perforated in a seat cover (C2) surrounding a cushion material (C1) of an automobile seat (S), a lighting module (20) installed in the cushion material (C1) to irradiate light toward the seat perforation hole (10), and a soft diffusion sheet (30) disposed between the seat cover (C2) and the lighting module (20). Generally, a car seat consists of a seat body on which the occupant sits, a backrest against which the back rests, and a headrest that supports the neck and head; each of these components is comprised of a shock-absorbing cushioning material and a seat cover that surrounds them. The seat cover is made of materials such as natural leather or artificial leather and functions to prevent contamination and enhance the durability of the seat. Recently, various features are being provided in automobile seats to offer passengers greater comfort, safety, and convenience. Additionally, various marks, letters, patterns, logos, etc. [hereinafter referred to as ‘seat logo’] expressing the name or symbol of the vehicle or manufacturer are displayed on the seat backs. Conventional seat logos were displayed by being engraved or embossed on the seat cover, or by attaching a separately produced logo label to the seat cover. For example, Registered Utility Model No. 20-0427021 (September 13, 2006) and Published Utility Model No. 20-2010-0006292 (June 22, 2010) disclose a structure for forming a logo and mark of a car seat cover that can express the logo and mark of the car in a three-dimensional relief form on the seat cover of the car backrest. In addition, Public Patent No. 10-2002-0072522 (September 16, 2002) discloses a logo label and a method for manufacturing the same, in which various decorative patterns are printed on a polycarbonate sheet with excellent strength and printability, and the opposite side of the printed surface is embossed so that it is exposed to the outside of the product, thereby making it easy to protect the decorative patterns and having excellent durability and workability. Meanwhile, Registered Patent No. 10-0543167 (January 6, 2006) and Registered Patent No. 10-0833699 (May 23, 2008) present a vehicle door scarf that improves the visibility of a vehicle name or vehicle logo day and night regardless of the surrounding environment, and helps make boarding and alighting for passengers safer and easier.
