ABSTRACT:
An apparatus for automatically mounting tension springs (tension coil springs) to suspend a seat frame and a pad receiving member forming an automotive seat is disclosed which comprises a supply hopper, a transfer mechanism, a guide member, a setting device and a direction restricting member. In the apparatus, when loaded into the supply hopper, the tension springs are separated from one another and then discharged one by one therefrom to the transfer mechanism, where they are rectified in the right and left deviations thereof by the guide member before they are delivered to the setting device. Then, the tension springs are caught and lifted up by the setting device and, during this lifting operation, they are rectified in the direction thereof by the direction restricting member, so that they can be automatically mounted to the seat frame as well as to the pad receiving member.
