ABSTRACT:
An apparatus for driving a seat testing machine that accurately tests the durability of the seat element, which includes a twisting assembly for providing both rubbing and impact engagements with the seat element, one common power source to activate a first mechanism to reciprocate the seat element along a first axis, and activate a second mechanism to reciprocate the twisting assembly about a rotary axis; and vertical loading and lifting mechanisms to repeatedly engage and disengage the twisting assembly from the seat element under a gravitational loading while simulating the varying weight of the occupant.
