ABSTRACT:
An upholstery support for the back rest of a vehicle seat, particularly a motor vehicle seat, is disclosed. The support comprises two half-shells connected with each other along at least a portion of their edges and form two hollow box-like arms (4) which extend downward from an upper area (3) of the upholstery support, whereby at least in one of the two half-shells (2) troughs (b 6, 7, 10) are provided, the troughs (6, 7) follow two lines that cross in the upper area and end at a distance from the crossing point. Adjacent to the crossing point, the ends of at least two of the troughs (6, 7) are connected with each other by a connecting element (13) which has a trough-like central zone between two edge zones adjacent to the half-shell (1) and securely connected therewith, which central zone bridges and stiffens the trough-less intermediate space between the trough ends to be connected with each other.
