Seat frame assembly

摘要

A seat frame supporting a seat cushion pad formed in a predetermined shape and engaging a skin for covering the pad includes a first roll formed frame having a closed rectangular cross sectional shape and formed so as to extend along the front edge and both side edges of the pad and a second roll formed frame having a closed rectangular cross sectional shape and formed so as to extend along the rear edge of the pad. Both end portions of the first roll formed frame and both end portions of the second roll formed frame are connected to each other. Accordingly, the strength of the seat frame is improved without increasing the weight of the seat frame.
