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.

Claims

1. A motor vehicle seat, comprising:

a backrest frame having a cutout in a side area;

a bridge plate reinforcing the backrest frame;

a side air bag arranged in the backrest frame; and

a panel having a C-shape that borders edges of the cutout, said panel comprising legs having inner and outer cheeks, wherein the outer cheeks reach over the cutout edges and the inner cheeks project inwardly;

wherein the panel, in an installed position, is open toward the bridge plate,

wherein ends of upper and lower inner cheeks of the panel are bent, thereby forming guiding surfaces for the air bag housing, and

wherein the ends of the upper and lower inner cheeks are reinforced by at least one detent nose for locking the panel with the bridge plate.

2. A motor vehicle seat according to claim 1, wherein said panel is plastic.

3. A motor vehicle seat according to claim 1, wherein said panel comprises three legs, each having an inner cheek and an outer cheek.
