Patent number: 7350814Abstract: 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.Type: GrantFiled: January 26, 2005Date of Patent: April 1, 2008Assignee: Namyang Ind. Co., Ltd.Inventors: Sung-Jong Hong, Kwang-Mo Koo, Jae-Uk Oh, Jae-Moon Han
