Abstract
A seat frame for use in an automotive seat. The seat frame is divided into four sections, that is, front, rear, right and left sections, and at least the right and left sections or side frame members are respectively formed in a substantially Z-shaped configuration. Namely, each of the side frame members comprises a vertically extending web, an upper flange and a lower flange projecting in opposing directions to each other with respect to the web, whereby, when loads are applied to the side frame members, the respective centers of shearing thereof are caused to exist in their webs or adjacent portions thereof, resulting in the increased strength.
