TILT STEERING COLUMN
PS-3
B: ENERGY-ABSORBING MECHANISM
! To absorb the backward movement energy generated in the engine in the event of a frontal col-
lision, an elliptical fitting type steering column pipe has been adopted. When an impact load ex-
ceeding a certain level is applied to the steering column, the elliptical fittings crash and their ends
come in contact with each other. The column bending load is supported by the fittings.
! Another measure to alleviate impact on the driver in the event of a collision is the ripping plate
which is located between the steering column and the tilt bracket attached to the steering support
beam. When a large impact load is applied to the steering column, the ripping plate is deformed
and torn progressively. The impact energy is absorbed during this process.
