Abstract
A powered tilt steering arrangement for a vehicle using a motor which rotates unidirectionally. The powered tilt steering arrangement basically comprises: a steering column having an upper shaft and a steering wheel assembly; a tilt bracket pivotally mounted on a mounting bracket fixed to a vehicle body and on which the steering wheel assembly is mounted; a drive source such as the motor; an actuator in response to a rotational force of the motor for actuating the tilt bracket to pivot through a predetermined angular width with respect to the mounting bracket in a reciprocatory motion; and a lock mechanism for locking the steering assembly when the actuator is stopped so that the steering wheel assembly is placed and held at a desired optimum driving position within the predetermined angular width. In addition, the powered tilt steering arrangement is preferably provided with a jump up mechanism which automatically tilts the steering wheel assembly toward a predetermined upper limit angular position by means of a spring force when the vehicle driver leaves the vehicle through a door so as not to obstruct the driver. Furthermore, the jumped up steering wheel assembly is returned to …
