Abstract
A vehicle seat back comprises firstly a rigid frame having first and second side uprights and top and bottom cross-members interconnecting the first and second side uprights, and secondly a resilient supporting sheet fixed to the rigid frame and placed so as to come directly into contact with the back of a user. The supporting sheet forms a bag that is fitted onto the rigid frame over its first side upright so as to cover the top and bottom cross-members and the first side upright, the resilient supporting sheet being fixed to the second side upright.
