A laminated abutment (10) comprising an inner strength member (11), an outer strength member (12), and an elastomeric member (15) comprising a stack of main layers (20, 30) that are flexible and of secondary layers (40) that are rigid. The stack comprises at least one first main layer (20) and at least one second main layer (30), each first main layer (20) presenting, in a lead-lag plane (PTRA), a first thickness (e1) that varies between a minimum first thickness (e1min) on the pitch-variation axis (AXPAS) and a maximum first thickness (e1max) on the flapping axis (AXBAT), and each second main layer (30) presenting, in a lead-lag plane (PTRA), a second thickness (e2) that varies between a minimum second thickness (e2min) on the flapping axis (AXBAT) and a maximum second thickness (e2max) on the pitch-variation axis (AXPAS).
