Description

Technical Field

[0002] Today's zero-gravity seats are innovative comfort seats. When using zero-gravity seats, passengers can adjust the seats to achieve a wide-angle reclining position, which brings a more comfortable sitting position. In the process of developing zero-gravity seats, it is necessary to simulate the static comfort evaluation of zero-gravity seats on ordinary seats, so that the optimal adjustment range of mechanical angles can be studied in advance, providing effective test data for department research. It can help department personnel provide test data support in advance for seat updates and upgrades (from ordinary seats to zero-gravity seats) to shorten the development time. However, there is a lack of dedicated body pressure distribution test benches for zero-gravity seats on the market.
