Embodiment Construction

[0021] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 and 2 , the cushion body 10 is used as a seat of a passenger transportation device, such as a motor vehicle (including a bus, a train, and an airplane). The seat includes a seat portion and a backrest. The cushion body 10 is composed of a core material 11 and a surface layer material 15 , and its shape corresponds to the passenger transport equipment on which the cushion body 10 is installed.

[0022] In an embodiment, the core material 11 is composed of a known melamine resin foam, and has a substantially flat shape with a predetermined thickness. The melamine resin foam is obtained by foaming a resin composition whose main components are melamine formaldehyde (melamine formaldehyde) coagulation material and a foaming agent, and has excellent lightweight performance. As the components used in producing the melamine re...

Abstract

A cushion body is provided with a core material formed by a melamine resin foam body, and a surface layer material formed by a polyurethane resin foam body in which an expandable graphite is dispersed, and covering a periphery of the core material. A through hole extending along a thickness direction of the cushion body is formed at a predetermined position of the core material. The surface layer material fills the through hole, and the core material and the surface layer material are integrally formed. The cushion body increases a lightweight property of the cushion body by the core material formed by the melamine resin foam body, increases a fire retardant property of the cushion body by the expandable graphite, and increases cushioning and durability properties of the cushion body by the polyurethane resin foam body.

Description

technical field [0001] The present invention relates to a cushion body and its manufacturing method, and more particularly to a seat cushion particularly suitable for motor vehicles, trains, airplanes and the like, the seat cushion having improved flame retardancy, and a manufacturing method of the seat cushion. technical background [0002] Generally, for cushions mounted on seats of passenger transport equipment such as motor vehicles, trains or airplanes, in addition to cushioning performance and durability, it is necessary to reduce its mass in order to save fuel consumption. In addition, the highest possible flame retardancy is required to suppress the spread of fire in the event of an accident. [0003] Japanese Patent Laid-Open No. 2002-129456 discloses a mat body. The structure of the mat body has carbon fiber mesh layered in layers along the in-plane direction perpendicular to the thickness direction of the mat body and compressed along the in-plane direction. , in...
