Embodiment Construction

[0090] Hereinafter, an embodiment of the seat cushion 1 of the present invention will be described.

[0091] The seat cushion 1 of the present invention is a seat cushion 1 including a seat cushion 2 which is arranged to face each other with a predetermined interval and is formed around an upper edge portion of the seat cushion 2 . The edge-shaped member 10, and a plurality of independent synthetic resin foams with a deflection of 20 mm or more measured according to the method described in JISK7221-2:2006 and a load of 2 to 100 N when deflected by 20 mm The rod-shaped or plate-shaped support body 3 is mounted, embedded or fixed in such a way that the above-mentioned seat cushion 2 is supported at one point or at multiple points in the direction of erecting between the above-mentioned edge-shaped members 10. It is provided on the above-mentioned edge-shaped member 10 or integrally formed with the above-mentioned edge-shaped member 10, and the plurality of support bodies 3 are a...

Abstract

The present invention solves the problem of realizing a lighter seat cushion (1) that has a good fit and ample cushioning properties when sat upon by: providing a seat cushion pad (2) that has a sitting surface on which a sitter sits formed thereon with an edge member (10) that forms an upper edge perimeter on the seat cushion pad (2) and a plurality of independent rod-shaped or flat plate-shaped support bodies (3) comprising a synthetic resin foam that has a bending deflection amount of 20 mm or more as measured according to the method described in JIS K7221-2:2006 and a load of 2-100 N at 20 mm of deflection; arranging the support bodies (3) in a row with a predetermined space therebetween; and providing a space (5) below the support bodies (3) that makes it possible to bend and deform the support bodies (3).

Description

technical field [0001] The present invention relates to weight reduction of a seat cushion for a vehicle, and particularly relates to a seat cushion characterized by excellent recyclability, applicability, and cushioning properties. Background technique [0002] Generally, a metal seat frame or steel wire is enclosed in a seat cushion, and polyurethane foam is generally used as a cushioning material, and the whole is covered with a skin material. The weight of the occupant is mainly supported by deflecting the polyurethane foam layer clamped between the seat frame or steel wire and the skin material in the direction of compression, and the cushioning and applicability are mainly achieved by deflecting the polyurethane foam layer in the direction of compression. Reaction force, restoring force and deflection are obtained. [0003] In addition, as a technique related to reducing the weight of a seat cushion, Patent Document 1 discloses a technique in which the seat frame has ...
