PROBLEM TO BE SOLVED: To provide a vehicle seat securing holding properties in a seat width direction for the upper body of a seating occupant on a side support regardless of the physical size of the occupant.SOLUTION: A side support 20 swells out to the front side of a seat by activating a bladder 42. An edge part 20A of the side support 20 swells out to the inside in a seat width direction by activating a bladder 44 in a condition where the side support 20 swells out to the seat front side. The edge parts of elastic embers 48, 50 causing elastic deformation are held on a side surface skin 32 of the side support 20, and displacement of the inside part in the seat width direction of the side surface skin 32 and displacement of the outside part in the seat width direction are allowed. Accordingly, the side support can be closely attached to the upper body of a seating occupant Q, and as a result, the holding properties in the seat width direction to the upper body of the seating occupant on the side support can be secured. |
