SummarySome vehicles may experience the second-row seat (configured as captain chairs or 60/40 bench) not sliding with the walk-in lever operation, although it slides with the sliding lever. The link bracket (2) may interfere with the kick plate (1) while operating the recline function, causing the deformation of the link bracket and preventing it from pulling the cable properly to unlock the seat for sliding. To eliminate this concern, the thickness of the link bracket has been modified to prevent deformation and the shape of the kick plate has been modified to prevent the interference.
