Claim:
1. A vehicle seat comprising: a seat pad that defines a seat outer shape and that is configured to support an occupant; a seat cover that covers the seat pad; and an air bag that is covered with the seat pad and that is configured to expand due to an inflow of a gas, wherein the seat pad includes a jump-out portion which has a greater fragility than other portions of the seat pad and from which at least a portion of the air bag is configured to expand out of the seat pad due to an expansion of the air bag, the other portions of the seat pad including a first unfolding portion provided at one side of the jump-out portion, and a second unfolding portion provided at an other side of the jump-out portion which is opposed to the one side, the air bag is configured such that, due to an expansion of the air bag, the air bag partially breaks the seat cover and expands out of the seat pad while the air bag pushes aside the first unfolding portion and the second unfolding portion so as to expand out from the jump-out portion, the first unfolding portion and the second unfolding portion are separated from each other by the jump-out portion, when viewed from a front side of the seat pad which faces an outside of the seat and when the air bag has not expanded, at least parts of the jump-out portion, the first unfolding portion, and the second unfolding portion are arranged in succession without any gap provided therebetween, the jump-out portion includes at least one first jump-out portion, which defines a hole that penetrates through the seat pad, and at least one second jump-out portion, and when the air bag has not expanded the at least one second jump-out portion defines a boundary at which the first unfolding portion makes contact with the second unfolding portion.
