Seat moving track assembly

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.
