Patent ID: 7922143

Claim:
A seat moving track assembly, comprising: a lower stationary rail which comprises a channel configuration, and comprises an opening which is continuously formed in a uniform interval in a lengthwise direction to a first end part thereof, and a groove part which is continuously formed in a uniform interval in a lengthwise direction to a second end part thereof; an upper moving rail which comprises a channel configuration which is movably coupled with the lower stationary rail; a locking member which is connected to the upper moving rail to enable coupling and releasing between the upper moving rail and the lower stationary rail by means of a force which is applied from an external part; and an elastic member which is disposed inside the upper moving rail to apply a predetermined force to the locking member, the locking member comprising an input part which protrudes to receive the force applied from the external part, a first stopping part which protrudes to perform coupling and releasing with the opening which is formed to the lower stationary rail, and a second stopping part which bends toward the opposite side to a direction in which the input part and the first stopping part are formed, and extends in a predetermined length to perform coupling and releasing with the groove part of the lower stationary rail, and the first stopping part and the second stopping part which are formed to the opposite sides of the locking member being formed to different positions.
