A frame of a motor vehicle seat with a longitudinal guide ( 20 ), a seat carrier ( 26 ), a front pair of oscillating cranks disposed between the longitudinal guide ( 20 ) and the seat carrier ( 26 ), and a padding support for a seat padding. A pinion ( 48 ) is rotatably disposed on one of the oscillating cranks ( 22, 23 ), an actuator ( 71 ) being associated with the pinion. A pivot unit ( 54 ) is disposed between the two oscillating cranks ( 22, 23 ) and is rotationally linked to the two oscillating cranks ( 22, 23 ) so as to be pivotal about an axial line. The pivot unit ( 54 ) is provided with a sector gear ( 62 ) that is centered on the axial line and meshes with the pinion ( 48 ), and an adjusting arm ( 64 ) is provided which is disposed between the pivot unit ( 54 ) and the padding support ( 30 ) so that the height of a front edge of the padding support ( 30 ) is adjustable by adjusting the sector gear ( 62 ).
