ABSTRACT:
A bonding device for manufacturing a vehicle seat, in which a foam cushion member secured on an upper die is pressed against a top cover member placed on a lower die for bonding those two members together. In the upper die, provided are main and auxiliary pressing mechanisms in such a manner that the cushion member is bodily pressed by the main pressing mechanism against the top cover member and then additionally pressed by the auxiliary pressing mechanism at a local area of the cushion member where a pressure of the main pressing mechanism is not sufficiently applied. In this way, the top cover member is positively bonded to the cushion member.
