Claims

[Scope of utility model registration request]

The front part of the seat is supported by a rotation support mechanism that connects a floor side bracket fixed to the vehicle body floor and a seat side bracket fixed to the seat so as to be relatively rotatable in the vertical direction by a pivot shaft. While the seat is fixed to the vehicle floor, the rear part of the seat is fixed to the vehicle floor via a removable fixing mechanism, and the rear part of the seat is fixed to the vehicle floor by the fixing mechanism, so that the seat is seated. In the vehicle seat, the seat can be set in a flip-up storage position by flipping up the seat and flipping it up around the pivot shaft by releasing the operation of the fixing mechanism and flipping the seat upward around the pivot shaft. In the support mechanism, the connection portion by the pivot shaft has an elongated hole engagement structure that allows the floor-side bracket and the seat-side bracket to be relatively displaced by a predetermined amount in the front-rear direction of the seat, and the connection portion by the pivot shaft A vehicle seat device, characterized in that a regulating means is provided for regulating relative movement in the seat longitudinal direction between the floor side bracket and the seat side bracket in the retracted position.
