Abstract
A tilt-telescopic apparatus for a steering system allows a tilt restraining means and telescopic restraining means to cooperate via one manipulating lever. A tilt restraint, telescopic restraint, tilt restraint release, and telescopic restraint release are conducive to simultaneous tilt and telescopic engagement by a single manipulation for convenience. The parts of the apparatus, including structural parts for transmitting power to the manipulating lever and the like that can be co-used, can be unified, thus resulting in simplified structure and reduction of manufacturing cost.
Claims8
A tilt-telescopic apparatus for a steering system, the system including a main housing, an inner pipe longitudinally movable in the main housing, a column housing coupled to an end of the inner pipe and an upper housing rotatably hinged to an end of the column housing, comprising:
- a manipulating lever rotatably hinged to a lower side of the main housing;
- telescopic restraining means formed at an end of the main housing and tightened by rotation of the manipulating lever to restrain the inner pipe;
- a cable connected to one end of the manipulating lever;
- a tilt lever connected to the other end of the cable and rotatably mounted at the upper housing;
- a fixation gear mounted at an upper side or lower side of the column housing and longitudinally formed with teeth along a curvature;
- tilt restraining means including teeth meshed with the teeth of the fixation gear and rotating in cooperation with the tilt lever for separating the teeth in relation to the rotating direction by pushing the teeth toward the teeth of the fixation gear or pulling the teeth;
- a jig protruder formed at one end of the manipulating lever;
- and
- an intermittently fixing member mounted at one surface of the main housing corresponding to a rotation restraining position of the manipulating lever and formed with a resiliently fixing unit having an opening at one side thereof for the jig protruder to be fixedly inserted thereinto.
