  • Publication number: 20220332222
    Abstract: Disclosed is a locking device for a walk-in seat of a vehicle capable of stably maintaining the locked state of the walk-in seat prior to a walk-in operation. An object of the present invention is to provide a locking device for a walk-in seat of a vehicle capable of stably maintaining the locked state of the walk-in seat prior to a walk-in operation (that is, the locked state of a drive plate for the walk-in operation of the seat) even if the engagement between the drive plate and a pawl is released due to deformation caused by a torsional load applied to a connection frame of the seat by additionally providing a separate component configured to prevent the drive plate from being rotated in an unlocking direction when a load is applied to a seat belt buckle.

  • Publication number: 20220314853
    Abstract: A backboard assembly for a vehicular rear seat is disclosed. The backboard assembly includes an upper part and a lower part, which are made of a hard plastic material. The backboard assembly prevents the formation of a gap between the lower part and a luggage board, regardless of the operational mode of the rear seat. When a seat back is folded, the upper part, the lower part, and the luggage board are aligned in a horizontal direction, thereby allowing the space for passengers in the rear seat to be completely integrated with a luggage compartment.
