According to the present invention, when the rear seats are mounted more than three rows behind the driver's seat, such as an RV & SUV vehicle, the rear seats of two rows and three rows are used to facilitate the getting on and off of passengers who get on and off the last three rows of rear seats. A walk in device is a rear seat walk which allows itself to move forward and to fold the seat back simultaneously.

In general, when RV & SUV cars have three or more rows of seats, the rear three rows of rear seats can be used to refold seatbacks with recliners and walk-in devices to help passengers get on and off. The seat itself can be moved to the front side.

That is, when the passenger rides outside the vehicle, the recliner lever mounted on the side of the rear seat is pulled forward, and when the passenger gets off, the recliner and the slider are unlocked by pressing the walk-in pedal indoors. The seat back is folded in the forward direction and at the same time the seat itself is slid forward so that the passenger's moving space is expanded to facilitate the passenger's getting off.

The forward movement of the seat is automatically made by the spring tension of the work-in device. When the seat is in a normal state (passenger seated), the spring is in the maximum tension state, and the tension force can be maximized. When the recliner and the slider are in the unlocked state, the tension force of the spring is applied and the seat is slid forward.

However, the recliner and walk-in apparatus of the related art as described above, when the recliner lever or the walk-in pedal is operated, the seat back rotates forward and the slider lock is released to secure the cargo loading space. There is a problem that the folding of 2 rows and 3 rows of seats is impossible (because the walk-in works at the same time during the back folding of the seat back), and the carelessness of 3 rows of passengers while the passengers are sitting on the 2 rows of seats If the foot-in pedal is pressed, the walk-in will operate, causing the second row passengers to be injured, and the walk-in pedal may cause foot problems when the passengers get on and off.

In addition, the walk-in device of the prior art was a factor of weight and cost increase because many mechanisms are used to fold the seat cushion and bag, and a separate fixing device, spring, damper, etc. to prevent the seat from falling backward. In addition, it is pointed out that the operation is inconvenient because the band set on the back side of the seat must be pulled in order to double-fold the seat.

Therefore, the present invention has been proposed in view of the above-mentioned matters appearing in the prior art, but the work in lever of the rear seat walk device is mounted on the top of the seat back, but the hinge end of the work in lever is the top of the back frame of the seat back. The free end handle is installed in a state capable of reciprocating up and down while being exposed at the upper end of the seat back so that the work in lever does not interfere with the passage when the passenger gets on and off. It is intended to allow the passenger to fold and slide the seat back at the same time by lifting up the work in lever handle exposed at the top of one side of the seat back, and also to operate the recliner only without the walk-in device. So that the seatback can be folded back and forth By inventing for another purpose to ensure a space for carrying a long load.
