  • the present disclosure relates generally to the field of seating for vehicles and more particularly, to a one-piece seat back frame assembly, a one-piece seat back frame assembly having an integrated head restraint and method of making same. DESCRIPTION OF THE RELATED ART
  • Seat structures such as, seat back frames, seat base cushion frames, low seat structures, and back frame seat belt towers can provide strength to a seat assembly to meet strength and/or durability requirements. These requirements are commonly covered by governmental regulations, such as, FMVSS and ECE or dictated by other groups, such as, by vehicle manufacturers and insurance groups. Seat structures can also be configured to meet the desires of customers (and hence vehicle manufacturers) for seat assemblies that provide increased functionality or utility, such as, rotating, folding, and sliding, while improving user- adjustable comfort. Achieving the desired strength, durability, stiffness, functional, and utility characteristics typically requires the use of additional components which can have an undesirable impact on mass, cost, and comfort. Therefore, seat structures are typically designed by balancing structural and functional characteristics against mass, comfort, and cost.
  • the present disclosure relates a one-piece seat back frame having an integrated head restraint for use in a vehicle seat assembly.
  • the one-piece seat back frame includes a first side member and a second side member spaced apart from the first side member, an upper cross member and a lower cross member.
  • the head restraint frame is integrated with the seat back frame and includes a first side member, a second side member spaced apart from the first side member, and an upper cross member.
  • the seat back frame and head restraint frame are formed from a single stamping and as a single unitary body stamped from a single piece of material.
  • a one-piece seat back frame having an integrated head restraint for use in a vehicle seat assembly.
  • the one-piece seat back frame includes a first side member and a second side member spaced apart from the first side member, an upper cross member and a lower cross member.
  • the head restraint frame is integrated with the seat back frame and includes a first side member, a second side member spaced apart from the first side member, and an upper cross member.
  • a lower cross bracket member is attached to the seat back frame such that the lower cross bracket member at least partially overlaps the seat back frame lower cross member forming a boxed section.
  • the seat back frame and head restraint frame are formed from a single stamping and as a single unitary body stamped from a single piece of material.
  • a method of manufacturing a one-piece seat back frame assembly having an integrated head restraint includes the step of forming a one-piece seat back frame having a head restraint frame from a single stamping and a single piece of material.
  • An advantage of the present disclosure is that the system and method of forming a one-piece seat structure is provided that does not require separate installation of a head restraint. Another advantage of the present disclosure is that a system and method of forming a one-piece seat structure is provided that has reduced mass and cost and increased strength. Another advantage of the present disclosure is that the one-piece seat structure is easier to manufacture and assemble. Yet another advantage of the present disclosure is that the one-piece seat structure has fewer weld joints and improved reliability. [0010] Other features and advantages of the present disclosure will be readily appreciated, as the same becomes better understood after reading the subsequent description taken in conjunction with the accompanying drawings.
