Abstract
The present invention relates to an integrated foam type headrest and a manufacturing method thereof. The headrest includes: a headrest cover; a cushion member which is attached to the inside of the cover before forming foam of a foam material, and is made of material having high elongation and low resistant resilience; a partition member, attached to the inside of the cushion member, for preventing the foam material from penetrating the cushion member; a stay frame for fixing the headrest to a sheet; and a foam material which surrounds the stay frame and is filled in the inside of the cover of the headrest by means of foam-forming. Accordingly, even though a cushion member having a thickness of 10 mm or more is installed to satisfy the softness properties of the headrest, the cushion member can be stably adhered to the cover, and can be reliably installed even at a curved part. Furthermore, sewing convenience is achieved, and thus mass production is possible.
