Abstract: A vehicle seat includes a backrest and a seat base as a seat part. The seat part includes a seat part frame, a trim side and an opposite harder side. The harder side has an outer peripheral surface with a recess contour. Fittings form a seat base to backrest pivot connection, for pivoting the seat base relative to the backrest and/or pivoting the backrest relative to the seat base. Pivotable hoop connections are connected to the vehicle seat frame adjacent to the opposite harder side. A storage hoop has hoop ends respectively connected to the respective pivotable hoop connections. The storage hoop is received in the recess in a stowed position, in which the hoop is disposed inwardly of a remainder of the outer peripheral surface. The stowed hoop may pivot out of the recess to a hoop deployed position, with the hoop extending outwardly from the opposite harder side.

Abstract: An adjustable vehicle seat configured to support an occupant in a vehicle may include a seat cushion portion, a seat back portion including a backrest movable relative to the seat cushion portion, and a contour linkage linked to the seat cushion portion and the backrest. The contour linkage may be configured to impose force on the backrest upon movement of the seat cushion portion relative to the backrest in at least one of a fore/aft, vertical, and rotational direction. The backrest may be configured such that a backrest contour is altered based on force imposed by the contour linkage in response to movement of the seat cushion portion relative to the backrest. The backrest contour may include at least one of a contour angle of an occupant-side surface of the backrest, a maximum offset of the occupant-side surface, and vertical height of a contour apex.

Abstract: A seat back structure includes a web extending about a central opening, and an inner flange extending about an inner perimeter of the web adjacent to the central opening. The seat back structure also includes an outer flange extending about an outer perimeter of the web. The inner flange, the outer flange and the web form a channel extending about the seat back structure, and the seat back structure is formed from a single piece of material.
