摘要： A vehicle seat drive for driving a vehicle seat includes a mechanical inchworm linear motion actuator. A linearly movable shaft is coupled to the vehicle seat such that the vehicle seat moves as the shaft moves. The actuator includes a jamming module and an actuation module. The jamming module has left and right jamming plates operable for engaging and disengaging the shaft while moving linearly with respect to the shaft. The actuation module is operable for applying linear forces on the jamming plates to have the jamming plates engage and disengage the shaft and move linearly with respect to the shaft. The actuation module applies a first linear force in a first linear direction on a jamming plate to have the jamming plate engage and move the shaft in the first linear direction thereby moving the vehicle seat in the first linear direction while causing the other jamming plate to disengage from the shaft. The process is repeated and reversed to move the vehicle seat in an inchworm fashion between fore and aft positions.
