PROBLEM TO BE SOLVED: To restrain a seat from sinking immediately after the occurrence of a rear collision of a vehicle and thereby prevent buckling of the seat with an inexpensive structure.SOLUTION: In a vehicle seat height adjustment device, a restraining body 10 is disposed at the rear side of a second link body 3a2. The second link body 3a2 is restrained from rotating to the rear side by the restraining body 10 contacting with a rear surface of the second link body 3a2. Thus, in a rear collision of a vehicle, the vehicle seat height adjustment device inhibits the seat 5 from sinking and prevents buckling at a current position by using an inexpensive structure without allowing the seat 5 to move to a lowest position as in a conventional seat.

    【課題】安価な構成により、車両の後突発生時に直ちにシートの沈み込みを規制してシートの座屈を防止できるようにする。【解決手段】規制体10を第2リンク体3a2の後側に配設し、規制体10の第2リンク体3a2の後面への当接により、第2リンク体3a2の後方への回動を規制する。そのため、安価な構成により、車両の後突時に、従来のようにシート5が最下位置に移動を許容することなくその位置でシート5の沈み込みを阻止して座屈を防止することができる。【選択図】図5
