Abstract
A tilt steering apparatus includes a fixed bracket, a movable bracket pivotably mounted to the fixed bracket by a center pin, a ratchet provided to the movable bracket, a pawl mounted rotatably to the fixed bracket and meshed with the ratchet for regulating the position thereof, a tilt-operating lever mounted rotatably on the center pin for engaging or disengaging between the ratchet and the pawl, a first biasing device disposed between the fixed bracket and the movable bracket so as to urge the movable bracket to its away-position, a stopper provided to the fixed bracket and engaged with the ratchet for regulating the movable bracket positioned at its away position, a pawl lever mounted rotatably on the center pin and mounting pivotally the pawl, a second biasing device disposed between the tilt-operating lever and the pawl lever for rotating the pawl lever in one direction, a hook lever mounted pivotally to the fixed bracket and engaged with the pawl lever for preventing the rotation in one direction thereof, a driving mechanism associated with the fixed bracket for driving an away-operating gear so that the away-operating gear may rotate the hook lever upon actuation of the driving mechanism for separating the hook lever from the pawl lever wherein the movable bracket is transferred to its away-position by the first biasing device, a lock lever mounted rotatably on the fixed bracket and rotated after rotation of the pawl lever upon rotation of the away-operating-gear; and a lock shaft mounted to the fixed bracket to be rotated by the lock lever upon rotation thereof and holding the ratchet with the stopper means for preventing the movement of the movable bracket at its away-position.
