Patent ID: 7134692

Claim:
An impact absorbing structure for a tilt steering system of a vehicle, comprising: a steering shaft having a longitudinal rigidity against compression; a steering column having a longitudinal rigidity against compression, engaged coaxially and rigidly in an axial direction with the steering shaft; a pivot rigidly attached to the steering column, to be an axis of a tilt rotation of the steering column; an upper bracket rigidly attached to the steering column for temporarily allowing a tilt motion of the steering column, and adapted to be relatively moved away from a vehicle body in response to an impact; a lower bracket having a notched portion defining a notch with an open end to a front of the vehicle body, rotatably engaged with the pivot in a closed end of the notch, for allowing the pivot being released from the notch in response to the impact; and a protrusion formed on an inner periphery of the notch and located adjacent to the closed end of the notch to prevent the pivot from being released from the notch toward the front of the vehicle body.
