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.

Apparatus for mounting tension springs automatically, the apparatus comprising:

a supply hopper provided with a separation mechanism for separating from one another tension springs formed with hook portions in the two ends thereof;
a transfer mechanism for transferring said tension springs discharged from said supply hopper to a predetermined position;
a guide member disposed outside said predetermined position for rectifying the right and left deviations of said tension springs while said tension springs are being transferred by said transfer mechanism;
a setting device located correspondingly to said predetermined position for catching and moving said tension springs to the mounting portion thereof as well as mounting said tension springs in position;
and,
