A vehicle seat capable of exhibiting both performances of regulating an input of a load and reducing vibration is provided. One aspect of the present disclosure is a vehicle seat including a coupling structure coupling a first member and a second member. The coupling structure includes a bolt inserted through the first member and the second member, an auxiliary member arranged so as to hold the first member between the auxiliary member and the second member in an axial direction of the bolt, a first elastic element arranged between the first member and the second member in the axial direction, the first elastic element being in contact with the first member and the second member, and a second elastic element arranged between the first member and the auxiliary member in the axial direction, the second elastic element being in contact with the first member and the auxiliary member.

A seat position adjusting device for a vehicle may integrate a seatback reclining mechanism and a mechanism for realizing a comfort relaxation posture into one simplified mechanism. The seat position adjusting device includes: a seatback frame and a seat cushion frame connected to each other at a predetermined seating angle; a fixed rail mounted on a bottom surface of a rear end portion of the seat cushion frame to be inclined upward and forward; a moving rail mounted to the fixed rail to be movable forward and backward; a pair of support frames mounted on a floor panel; a front link hinge-coupled between a bottom surface of a front end portion of the seat cushion frame and a front end portion of an associated one of the support frames; and one or more support links hinge-coupled between the moving rail and the associated one of the support frames.

A seat device includes a cushion portion configured to elastically support a seated person and a seat frame configured to support the cushion portion. The cushion portion includes a plurality of divided cushions divided in a seat width direction. The plurality of divided cushions each include a seat pad a seat cover that individually covers each seat pad, and a resin member that is engaged with at least one of the seat cover or the seat pad and is thus individually integrated with the seat pad covered by the seat cover. The resin member includes a snap-fit structure fixed to the seat frame by inserting from a seat front side to a seat back side.
