Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a body pressure distribution test bench for automobile zero-gravity seats. Background Art

[0002] Today's zero-gravity seats are innovative comfort seats. While in use, occupants can adjust the seat to achieve a wide reclining angle, providing a more comfortable seating position. However, during the development process, static comfort evaluations of zero-gravity seats must be simulated on standard seats. This allows for pre-determined evaluation of the optimal mechanical angle adjustment range, providing effective test data for research departments. This can provide pre-determined test data support for seat upgrades (from standard seats to zero-gravity seats), shortening development time. However, there is a lack of dedicated pressure distribution test benches for automotive zero-gravity seats on the market. For example, existing Chinese patent number CN219551876U discloses a utility model entitled "A Multifunctional Test Bench for Body Pressure Distribution and H-Point Testing of Automotive Seats." While this patent allows for pressure distribution testing of different seat types, it cannot adjust the seat angle to simulate the static comfort evaluation of zero-gravity seats using standard seats. There is an urgent need for a pressure distribution test bench for automotive zero-gravity seats. Utility Model Content
