PROBLEM TO BE SOLVED: To provide a lumbar support capable of suppressing a foreign matter feel.SOLUTION: A base part is connected to a frame of a seat back supporting a back pad via a connection part. A support part is arranged between the back pad and the base part. A least one of an upper part and a lower part of the support part is fixed to the base part while a center in a vertical direction of the support part separates from the base part by a predetermined interval. Each of the support part and the base part is constituted by a plate material elastically deformable. Thus, the support part easily deforms elastically, can elastically deform into a smoothly continuous shape, and has an effect to suppress a foreign matter feeling due to a lumbar support.SELECTED DRAWING: Figure 4

    【課題】異物感を抑制できるランバーサポートを提供すること。【解決手段】バックパッドを支持するシートバックのフレームに基部が連結部を介して連結され、バックパッドと基部との間に支持部が配置される。支持部の上下方向の中央部が基部と所定間隔を隔てつつ、支持部の上部および下部の少なくとも一方が基部に固定される。支持部および基部がそれぞれ弾性変形可能な板材から構成される。これにより、支持部を弾性変形し易くしつつ、滑らかに連続した形状に支持部を弾性変形できるので、ランバーサポートによる異物感を抑制できる効果がある。【選択図】図4
