両用シートクッションパッドに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat cushion pad, and more particularly to a vehicle seat cushion pad which is reduced in weight and cost without impairing sitting comfort, riding comfort and durability.
【０００２】[0002]
【従来の技術】従来、自動車等のシートに取り付けられ

構成され、金型にウレタン原液を注入して発泡成形する
ことにより製造されている。2. Description of the Related Art Conventionally, a seat cushion pad to be attached to a seat of an automobile or the like is made of polyurethane foam, and is manufactured by injecting a urethane undiluted solution into a mold and foam-molding the same.
【０００３】ところで、車両のシートにおいては、座面
の尻下部は搭乗者の体重が最も多くかかり、この部分の
材質は座り心地や乗り心地と密接な関係がある。従っ
て、尻下部の構成材料は座り心地、乗り心地の観点から
重要であるが、それ以外の部分は体重の負荷も小さく相
対的な重要度は低い。By the way, in the seat of a vehicle, the occupant's weight is the heaviest at the lower part of the seat surface, and the material of this part is closely related to sitting comfort and riding comfort. Therefore, the constituent material of the lower butt is important from the viewpoint of sitting comfort and riding comfort, but the weight of the other parts is small and the relative importance is low.
【０００４】しかし、従来のシートクッションパッド
は、サイド部や腿下部等の一部が異種材料で構成される
場合もあるが、一般的にはその全体が同一の材料で構成
されている。このため、座り心地や乗り心地に重要な尻
下部に用いられる材料で重要度の低いそれ以外の部分も
構成される結果、シートクッションパッド全体として重
量アップやコストアップの要因となっていた。[0004] However, in the conventional seat cushion pad, a part of the side part, the lower part of the thigh, and the like may be made of a different material, but generally the whole is made of the same material. For this reason, the material used for the lower part of the buttocks, which is important for sitting comfort and riding comfort, also constitutes other parts of low importance, resulting in an increase in weight and cost of the entire seat cushion pad.
【０００５】一方で、低燃費化のための車両の軽量化は
自動車業界の重要な課題であり、また、低コスト化も常
に望まれている。[0005] On the other hand, weight reduction of vehicles for fuel economy is an important issue in the automobile industry, and cost reduction is always desired.
【０００６】そこで、シートクッションパッドの軽量化
のために、座面の尻下部を除く部位を、尻下部を構成す

の高いポリウレタンフォームで構成することも提案され
ている。このシートクッションパッドでは、尻下部以外
の部分を低密度材料とすることで軽量化を図り、かつこ
の低密度材料を高反発弾性材料とすることで座り心地や
耐久性の良いものにしている。Therefore, in order to reduce the weight of the seat cushion pad, the portion of the seat surface other than the lower rear portion may be formed of a polyurethane foam having a lower density but a higher rebound resilience than the polyurethane foam forming the lower rear portion. Proposed. In this seat cushion pad, a portion other than the lower rear portion is made of a low-density material to reduce the weight, and the low-density material is made of a high-rebound resilience material to improve comfort and durability.
【０００７】[0007]
【発明が解決しようとする課題】しかしながら、低密度
品であっても高反発弾性のポリウレタンフォームは高価
であり、低密度、高反発弾性のポリウレタンフォームで
尻下部以外の部分を構成することは、価格面で不利であ
る。However, even if it is a low-density product, a high resilience polyurethane foam is expensive, and it is difficult to constitute a portion other than the lower back portion with a low-density, high resilience polyurethane foam. It is disadvantageous in terms of price.
【０００８】一方、シートクッションパッドにあって
は、座面の尻下部以外の部分には大きな負荷はかから
ず、乗り心地や耐久性の面で尻下部以外の部分に高反発
弾性の材料を用いることは必ずしも必要とされない。On the other hand, in the seat cushion pad, a large load is not applied to portions other than the lower rear portion of the seat surface, and a material having high rebound resilience is applied to portions other than the lower rear portion in terms of ride comfort and durability. It is not required to use.
【０００９】本発明はこのような実状に鑑みてなされた
ものであって、座り心地、乗り心地及び耐久性を損なう

用いても、十分に良好な性能を得ることができる。[0011] As described above, in addition to sitting comfort and riding comfort,
From the viewpoint of durability, a large load is not applied to the parts other than the lower part of the buttocks, and if the hardness of the material forming the lower part of the lower parts is almost the same, use a low-density inexpensive material for the parts other than the lower part of the buttocks. However, sufficiently good performance can be obtained.
