摘要: Angular vibration isolation is provided for a seat back member in combination with mechanism adjusting the angle. Eccentrically mounted cylindrically shaped cam members located at each side of frame can be adjustably rotated within guide channel carried by frame. The cams are positioned distance from pivot axis on around which tilt order to adjust angle tilt. One parallel, opposed flanges define channels spaced its respective resilient means such as thick pad elastomeric material fills space between and said one flange. pads compressed forced forwardly against occupant's due vehicle vibration, thus permitting driven rearwardly while position remains relatively fixed.
