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

Seat component adjustment actuator, vehicle seat, and method of adjusting a seat component

A headrest system comprises a headrest, a guide bracket to which the headrest is mounted and an actuator coupled to the headrest and the guide bracket. The actuator is configured to displace the headrest relative to the guide bracket. The actuator comprises a spindle transmission and a power drive coupled to the spindle transmission. The spindle transmission comprises a spindle and a spindle nut engaged with the spindle. The power drive is arranged in a cavity defined within an outer shell of the headrest.

Headrest system and method of adjusting a headrest

A headrest system comprises a headrest, a bracket to which the headrest is mounted and an actuator. The actuator is configured to displace at least a portion of the headrest relative to the bracket in a displacement direction which is transverse to a longitudinal member of the bracket. The actuator comprises a spindle transmission and a power drive coupled to the spindle transmission. The spindle transmission comprises a spindle and a spindle nut engaged with the spindle. The power drive is arranged in a cavity defined within an outer shell of the headrest.

An adjusting device for a lumbar support includes a pair of spaced guide members. A first adjusting member is coupled to the pair of guide members and displaceable along the pair of guide members and configured such that the lumbar support is adjusted when the first adjusting member is displaced. A second adjusting member is displaceable along the pair of guide members. A drive mechanism for effecting an adjustment of the lumbar support includes a motor provided on the first adjusting member so as to be displaceable along the guide members jointly with the first adjusting member.
