The present invention relates generally to seats and more specifically to a hydro-formed seat adjuster system.
It is well known in the automotive vehicle seating industry to employ seat adjusters which carry a seat support frame upon which are mounted a seat bottom cushion and a seat back cushion. The seat adjusters can be manually operated or automatically driven by electric motor actuators. Many traditional power seat actuators employ a front torsion tube and a rear torsion tube. Motion links are typically fusion welded onto each torsion tube. These torsion tubes control lifting and tilting of the seat adjuster, seat frame and cushions. One such conventional assembly is disclosed within U.S. Pat. No. 5,899,428 entitled “Vehicle Power Seat Adjuster with Self-Locking Track Assemblies” which issued to Gauger on May 4, 1999, which is incorporated by reference herein.
