Abstract: A vehicle seat is equipped with a seatback having a mounting portion, a headrest having a headrest frame and an electric component, a first connector, and a second connector. The first connector has an engaging portion engaged with a hole of the headrest frame, a protrusion engaging the second connector, and a first connector terminal electrically connected to a lead wire of the electric component. The second connector has a first engaging piece engaged with a hole of the guide bracket from the outside of the guide bracket, a second engaging piece engaged with the protrusion of the first connector from the outside of the first connector, and a second connector terminal electrically connected to a lead wire wired in the seatback and the first connector terminal. The engagement between the hole of the mounting portion and the first engaging piece of the second connector can be released irreversibly.

Abstract: A vehicle seat is provided with a seat sliding mechanism (a) including a lower rail and an upper rail fitted and moved in the lower rail, a seat structure (b) equipped with a seat cushion frame including a seat side member and a seat back frame, an upper riser (c) fixed to the upper rail and supporting the seat structure, and a seat inclining mechanism (d) that enables inclining of the seat structure for the upper riser. When the seat structure is inclined by the seat inclining mechanism, an angle between the seat cushion frame and the seat back frame is maintained and the rear of the seat cushion frame is located on the upside of the rear of the seat cushion frame in a state before the seat structure is inclined by the seat inclining mechanism.
