Patent ID: 7780138

Claim:
A seat moving track assembly, comprising: a stationary rail which has a channel configuration, and has at a lower part of one side thereof recesses formed successively in a lengthwise direction with a uniform pitch and has at an upper part of the other side thereof openings formed successively with the same pitch as the recesses; a moving rail which is disposed inside of the stationary rail and has a channel configuration to be movably coupled to the stationary rail, and which has at a lower part of one side thereof first side holes to correspond to the recesses and has at an upper part of the other side thereof second side holes to correspond to the openings; a locking member which is rotatably disposed inside of the moving rail and which has, when rotated in one direction, a plurality of first stopping protrusions projecting through the first side holes to be coupled into the recesses of the stationary rail and a plurality of second stopping protrusions projecting through the second side holes to be coupled into the openings of the stationary rail; an elastic connecting member which is mounted inside of the moving rail and has a shaft supporting part to rotatably support the locking member and an elastic pressing part to rotate the locking member in one direction; and unlocking means which has an operating pin slid by an outer force and rotating the locking member in the other direction to release a coupling between the first stopping protrusions and the recesses and a coupling between the second stopping protrusion and the openings, a connecting block mounted on the moving rail to guide a sliding of the operating pin, and a return spring coupled to the connecting block to support the operating pin.
