An actuator includes a pinion engaging a seat height adjustment mechanism. A brake drum fixed to the seat defines an outer brake race. A brake hub integrated with the pinion, rotatable in the brake drum, defines an inner brake race. Rolling brake elements between the brake races lock the brake hub to the brake drum in the absence of actuator input. A clutch drum covers the brake races, defines an outer clutch race, and includes clutch tabs to displace the rolling brake elements, unlocking the brake hub, responsive to actuator input. A driver cam rotatable within the clutch drum defines an inner clutch race. Rolling clutch elements in the clutch races transmit actuator input to the clutch drum and permit rotation of the driver cam relative to the clutch drum in the absence of actuator input. An exterior cup fixed to the brake drum defines a housing for the actuator.

Seat height adjustment actuator

An actuating device comprises a handle, a housing, and a driven member connected to the handle, the driven member being rotatable about a longitudinal axis thereof, the housing containing: a brake mechanism, for restricting rotation of the driven member when the brake mechanism is engaged; a means for disengaging the brake mechanism; a means for rotating the driven member in either the clockwise or counter-clockwise direction; and, a clutch mechanism for restricting reverse rotation of the driven member when driven in the clockwise or counter-clockwise direction. The actuating device of the invention is particularly suited for actuating a seat height adjustment mechanism of a vehicle.
