A multiple position convertible seat assembly for a boat includes three seat frames pivotally coupled to the boat and to each other to move from a first position as a seat, a second position as a lounge seat with leg support, and a third position forming another seat. In the third position, the seat includes a foldout cushion exposing a work surface.

A hybrid support structure for a backrest part of a vehicle seat or a back bench seat, which is formed from a metal structure and a plastic structure, the metal structure including at least one connecting profile disposed between two side rail profiles of the hybrid support structure. It is provided that the connecting profile, together with a central rib of a web structure designed as a plastic structure follows a load path-optimized main load line, which runs between two connecting points of the connecting profile on the side rail profiles, taking into account a force acting upon the hybrid support structure in at least one assumed load case.

An integrated child booster seat, to allow more securely switching of a usual seat and a child seat with a relatively simple configuration, in which a seat cushion is configured by a cushion part in which a seat for a general passenger is formed on one side and a child seat is formed on the reverse side, a coupling pipe which coaxially supports the front and the back of the cushion part and which is swingably held with outside of lateral sides of the cushion part in the center of turning, supporting parts that bind and support the cushion part, and binding release parts that release binding by the supporting parts of the cushion part.

A work surface is provided with a lock assembly. The lock assembly includes an actuator plate and a locking plate. The actuator plate includes a pin. The locking plate includes an angled slot that receives the pin of the actuator plate. Actuation of the actuator plate in a first direction causes the pin to move within the angled slot of the locking plate. The movement of the pin within the angled slot causes movement of the locking plate in a second direction, thereby actuating the locking plate between a locked configuration and an unlocked configuration.

A chair includes a seat and a back rest, both of which pivot about respective axes between first and second positions thereof about parallel axes of rotation. The seat's second position is inclined relative to a first seat plane defined by the seat's first position. The backrest's second position is essentially parallel to the first seat plane such that the chair switches between seating and support configurations. In the seating configuration, the seat and backrest are their respective first positions such that the chair accommodates a seated person. In the support configuration, the seat and backrest are in their respective second positions such that the chair accommodates a person's chest on the backrest's rear face.

A vehicle seat having a seat with a seat frame, a backrest with a backrest frame, the backrest frame being pivotally mounted relative to the seat frame around a first transverse axis between at least one deployed position for receiving a seat occupant and a folded position in which the backrest frame is folded opposite the seat frame. The seat further includes on each side of the seat a first and a second connecting rod intended to be fixed on a support of the seat so as to be pivotable about a respective transverse axis to lift the backrest frame relative to the seat support.
