Inclination adjuster for a vehicle seat

Reclining mechanism for a car seat back is made up of at least three, preferably at lest four, parallel plates (E1 - E4). One plate in each pair (E12, E23, E34) is bent (K) at one end so that it contacts the adjacent plate. The plates are welded together at this point. The bend in the next pair is staggered from that in the first, so that the welds are staggered.
