Abstract

A seat component adjustment actuator (1) comprises a housing, an electric motor (5), and a gearing (10) coupled to the electric motor (5) and comprising at least three worm transmission stages (11-16). A first worm transmission stage (11, 12) comprises a first worm (11) and a first worm gear (12) engaged with the first worm (11). A third worm transmission stage (15, 16) comprises a third worm (15) and a third worm gear (16) engaged with the third worm (15). The first worm (11) is supported in the housing such that the first worm (11) is rotatable about an input rotation axis. The third worm gear (16) is supported in the housing such that the third worm gear (16) is rotatable about an output rotation axis which is transverse to the input rotation axis.
