  • Patent number: 11318870
    Abstract: A seat back frame for a vehicle according to an embodiment of the present invention comprises: a frame body consisting of a thermoplastic fiber reinforced composite material; a reinforcing agent joined to the inside of the frame body; and a cover sheet joined to the outside of the frame body. According to the present invention, the frame is lightweight while maintaining rigidity and strength like a steel frame, and a cover sheet is joined thereto, thereby enabling a board which is further joined to the seat back frame to be omitted, which leads to the achievement of a slimmed and fabric-integrated seat back frame for a vehicle. Also, a cover sheet is joined to a body frame by using a vacuum adsorption scheme, which leads to the achievement of a method for manufacturing a seat back frame for a vehicle having improved joining force and increased merchantability.
