Disclosed herein is a combination in a motor vehicles. The combination comprises a seat with an inclinable seatback; a seat slide unit for sliding the seat to a desired position, the seat slide unit including movable and stationary rails; a belt retractor connected to the movable rail to move therewith, the belt retractor including a check mechanism which checks the feeding of a seatbelt from the retractor when a certain degree of acceleration is applied thereto; a lock mechanism incorporated with the seat slide unit to lock the movable rail at a desired fore-and-aft position relative to the stationary rail; an operation handle held by the movable rail and pivotally movable between a first position and a second position, the first position being a position to effect the locking of the movable rail relative to the stationary rail, and the second position being a position to cancel the locking of the movable rail relative to the stationary rail; a walk-in mechanism incorporated with the lock mechanism for cancelling the locking of the movable rail relative to the stationary rail when the seatback is inclined forward; a first electric device for making the check mechanism inoperative when electrically energized; a second electric device for energizing the first electric device when the operation handle assumes the second position; and a third device for causing the operation handle to take a position other than the second position thereby to keep the first electric device deenergized when the seatback is inclined forward.
