Abstract
A control assembly for use in regulating movement of a vehicle seat back is provided. The control assembly uses damping fluid to regulate the degree of damping applied to the seat back. The control assembly includes one or more initiator assemblies. A selected one or more of them can be activated when a front and/or rear end collision occurs. When an initiator assembly is activated, a transfer member changes between closed and open states to regulate a path for damping fluid. The control assembly also includes a piston head having first and second sides. Movement of the damping fluid occurs relative to these two sides. The piston head can include at least one bore, which functions as an additional path for damping fluid. The control assembly preferably also includes a temperature compensation assembly to accommodate temperature changes in the damping fluid.
