Abstract
A vehicle seat device includes a seat cushion frame and a seatback frame including a lower-side frame supported at a lower end portion thereof to be tiltable relative to a rear end portion of the seat cushion frame, an upper-side frame arranged at an upper portion of the lower-side frame, and a center bending mechanism coupling the lower-side frame and the upper-side frame to be bendable forward, wherein the center bending mechanism bends the upper-side frame about a rotational center that is ahead of a seatback outer layer covering a front surface of the seatback frame. The movement of the upper-side frame when tilted comes close to the movement of the passenger who bends forward. The slip between the seatback outer layer and the back of the passenger can be minimized, and thus, it becomes possible to lessen an uncomfortable feeling of a passenger.
