PROBLEM TO BE SOLVED: To provide a seat cushion for a vehicle such as an automobile or the like which is capable of sufficiently protecting a lower back and a back by avoiding any positional deviation during an operation of a vehicle such as an automobile.SOLUTION: A seat cushion for a vehicle comprises an air pack which has a flexible sealing bag 20 comprising a back part 22 and a lower back part 24, the back part being larger in capacity than the lower back part, an elastic body 30 which comprises a back part 42 and a lower back part 44 and resides in the sealing bag and whose shape is substantially identical to that of the sealing bag, and air which is contained in the sealing bag 20 with the elastic body 30 so as to be capable of freely flowing between the back part 22 and the lower back part 24 of the sealing bag. The sealing bag 20 is formed so as to have a clearance for allowing the air to flow between itself and the elastic body 30. The elastic body 30 is formed like a seat by entangling a fibrous body and/or a thready body so as to allow the air to flow therein, and further the air is contained by a volume which allows the entire air pack 2 to be shaped like a seat. |
