Abstract
A vehicle seat device includes an SB main frame that is joined to a seat cushion via a reclining shaft; an SB subframe that is swingable with respect to the SB main frame at least about a roll axis; a backrest that is installed on the SB subframe; and a lower support wire and an upper support wire that limit rearward movement of the SB subframe and allow movement of the SB subframe about the roll axis. A straight line connecting between the front end and the rear end of the lower support wire is inclined with respect to a normal line so as to rise toward the front, the normal line being normal to a straight line connecting between an upper end of the SB main frame and the reclining shaft.
