Vehicle seat

A vehicle seat comprising a cushion frame, a back frame, and a rotation shaft pivotally supporting the cushion frame and the back frame such that the cushion frame and the back frame are rotatable around an axis thereof along a right-left direction, wherein

• the vehicle seat is configured to be rotatable around the rotation shaft between a used position on a front side with respect to the rotation shaft and a storage position on a rear side with respect to the rotation shaft in a state where the back frame is folded to the cushion frame side,
• the cushion frame and the back frame each include a pair of side frames forming portions on both end sides thereof in the right-left direction and extending in a front-rear direction in the storage state,
• the side frames each include a base portion forming a portion on one end side in the front-rear direction in the storage state, and an eccentric portion which is eccentric inward or outward in the right-left direction with respect to the base portion in the storage state and for which rigidity against bending in the right-left direction is set so as to be lower than that of the base portion,
• the vehicle seat is used for a vehicle having an on-board object on the front side of the cushion frame and the back frame in a storage state where the cushion frame and the back frame are stored at the storage position,
• the cushion frame and the back frame each include a first frame and a second frame provided at a predetermined interval in the front-rear direction so as to extend in the right-left direction in the storage state, and a support member extending between the first frame and the second frame and supporting a cushion member between the pair of side frames,
• the support member extends between the first frame and the second frame at a position eccentric upward or downward with respect to the first frame and the second frame in the storage state,
• each side frame includes a connecting portion connecting the base portion and the eccentric portion, and
• rigidity of each connecting portion against bending in the right-left direction is set so as to be lower than that of each base portion of the side frame.
