Abstract

A seat, especially a motor vehicle seat, which includes a seat component and a back component. The seat component and/or back component each include a spring core, a cushion layer, and a ribbed upholstery cover provided with securing tabs fixed to the rib seams. Only an end portion of each securing tab is attached to the respective rib seams with a free end portion of the securing tabs being adapted to be fixed by a fastening element to the spring core. A method is also proposed wherein at least one single strip of material is disposed so as to extend transversely of the ribs of the upholstery cover with the strip of material being fixed at the respective seams and subsequently severed mid-way between adjacent ribs so as to form a plurality of juxtaposed securing tabs. The free end portions of the resulting securing tabs are then folded up to enable a fixing by the fastening elements.
