[0002] In the automotive industry, when the vehicle seats of an automobile are newly upgraded or there are updated requirements in relevant laws and regulations, relevant collision tests (in-vehicle state) need to be carried out on seats in different layout states to ensure the safety of passengers. In the past, the tests were carried out by adapting the corresponding benches according to the lengths of different vehicle body segments. This led to a large number of benches that needed to be adapted and could not be reused, resulting in waste of resources and low efficiency.
