An electric seatback-folding device for emergency escape enables a controller to accurately recognize whether a seatback (or a seatback frame) is in a locked state or an unlocked state using a microswitch. Folding of the seatback for emergency escape is smoothly performed without malfunction or a control error by operation of a motor in response to a current control signal of the controller.

A seatback-folding device for emergency escape for vehicles is equipped with a simply structured mechanism for emergency escape. A locking operation at the time of unfolding of a seatback of a second-row seat and an unlocking operation at the time of folding of the seatback of the second-row seat are performed by ascending/descending of a shaft caused by operation of a lever, thereby not only enabling an occupant sitting on a third-row seat to quickly fold the seatback of the second-row seat and thus to easily secure an emergency escape route, but also reducing the number of components, weight, the number of assembly processes, and manufacturing cost compared to a related art.

Disclosed is a speed reduction device for a vehicle motor. The speed reduction device includes an output gear connected to an output shaft of the motor, a transmission gear engaged with the output gear, a cam formed to be integrated with the transmission gear, a cycloid inner gear, a pair of wedges compressed against the inner peripheral surface of a through hole of the cycloid inner gear by elastic restoring force of a spring and configured to closely contact the cam, a ring gear partially engaged with the cycloid inner gear when the cycloid inner gear is eccentrically rotated, an end plate, and a final output gear configured to finally output rotational force of the cycloid inner gear, thereby preventing backlash between gears during rotational driving of the motor and reliably preventing movement of a seat after swivel adjustment is completed.
