  • Multi-axis seat durability test machine
    Patent number: 5641917
    Abstract: A multi-axis seat test machine for use with seats is disclosed. The test machine includes a loading element and a seat mount. A selectively actuable fore-aft displacement mechanism is disposed between the loading element and the seat mount and operably displaces one of the seat mount and the loading element relative to the other in the fore-aft direction. A selectively actuable lateral displacement mechanism is disposed between the loading frame and the seat mount and operably displaces one of the seat mount and the loading frame relative to the other in a lateral direction. An engaging member simulates, at least in part, a shape of a human posterior for engagement with the seat. The loading element operably biases the engaging member against the seat in a substantially vertical direction with a predetermined vertical load.
