Abstract: A motor vehicle seat includes a backrest frame having a cutout in its side area for the passage of the side air bag. The cutout is closed off to the front by a bridge plate and the edges of the cutout are bordered by a panel. The panel is made of legs having a two-cheek construction, with an inner and an outer cheek. The outer cheeks reach over the cutout edges and the inner cheeks project inwardly The panel has a C-shape and, in the installed position, is open toward the bridge plate. The ends of the upper and lower inner cheeks of the panel are bent toward one another and thus form guiding surfaces for the air bag housing.
