Abstract: A reclining device including: a lower frame member that configures a portion of a frame of a vehicle seat; an upper frame member that configures a portion of the frame of the vehicle seat; a recliner that is provided between and welded to both the lower frame member and the upper frame member, and that couples the upper frame member to the lower frame member such that a relative rotation angle of the upper frame member is adjustable relative to the lower frame member; a lower side engagement portion that is provided at the lower frame member and that is formed in a circular arc shape that is concentric with the recliner; and an extension member that extends from the upper frame member toward a lower frame member side.

Abstract: A headrest device comprising: a left and right pair of headrest stays that are fixed to a seatback frame in a state projecting out toward an upper side of a seatback of a vehicle seat; a headrest main body that has the pair of headrest stays inserted inside from a lower face of the headrest main body and that is supported by the pair of headrest stays; and a removal restricting mechanism that is provided inside the headrest main body, that restricts removal of the headrest main body from the pair of headrest stays, and that releases the restriction by a release operation portion positioned inside the headrest main body being press-operated from an outside of the headrest main body.

Abstract: A vehicle seat including: a moving member that moves as one with a rail configured to move in a vehicle front-rear direction; a seat cushion that is coupled to the moving member through a lifter mechanism, is disposed above the rail, and is configured such that the top-bottom direction position of the seat cushion is capable of being adjusted by the lifter mechanism; and a gap concealing member that extends between a vehicle rear direction lower portion of the seat cushion and the rail to conceal a gap between the seat cushion and the rail. The gap concealing member is integrally formed from the top end portion to the bottom end portion.
