The present invention relates to a hybrid seat frame for a vehicle and provides a hybrid seat frame for a vehicle including a main frame formed of glass fiber and a reinforced frame formed of carbon fiber to secure stiffness in a direction perpendicular to the longitudinal direction and torsional stiffness and to reduce its weight, thereby improving fuel efficiency of the vehicle.
Claims1
A hybrid seat frame for a vehicle comprising:
- a main frame formed of glass fiber and having a pair of supports vertically arranged at both sides of the main frame;
- and
- a reinforcing frame coupled to each support of the main frame, the reinforcing frame being formed of carbon fiber,
- wherein each support of the main frame and the reinforcing frame respectively has a -shaped cross-section which has an open front and a closed rear, wherein each support of the main frame is inserted into an inner circumferential surface of the reinforcing frame through the open front of the reinforcing frame,
- wherein the reinforcing frame has holes arranged along a longitudinal direction of the reinforcing frame, wherein the main frame includes rivets each inserted into each hole of the reinforcing frame, wherein the rivets are formed of the glass fiber and molded with the main frame by an injection molding solution flowed into the holes of the reinforcing frame when performing injection molding of the main frame.
