Abstract
A headrest for an automotive seat which comprises a head contact portion, a stretchable rear portion which includes an elastic webbing, and an air bag disposed within those two portions, all of them being fixed upon the top of seat back of the seat. The expansion or shrivelling of the air bag, by using an air pump, causes the headrest to raise for turning upright the head contact portion, or permits the air bag to be compressed by the contracting force of the webbing, thereby lowering the headrest.
