Abstract
A seat moving apparatus performs adjustments of a seat portion in a longitudinal direction of the vehicle as well as height or tilting adjustments using only one electric motor to decrease the number of elements of the apparatus and to reduce the weight and size of the apparatus. A linkage for driving a seat for a vehicle is disclosed which is arranged in such a manner that first and second nut members are matably attached to operational shafts connected to the single motor. The first nut members are fixed to a floor of the vehicle. The second nut members are attached to the seat through linkages. A clutch body of each nut member can be, by a clutch operation mechanism, selectively switched between a movement state and a non-movement state. In the movement state, a clutch body of the clutch mechanism is positioned at a second shifting position and the nut members are engaged with and longitudinal moved along the threaded operation shafts. In the non-movement state, the clutch body is positioned in a first shifting position and the nut members are not moved during rotation of the operational shafts. The first nut members adjust the positions of the seat in the longitudinal direction and the second nut members adjust the height or tilt of the seat.
