Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a rear seat backrest bumping and creeping tool. Background Art

[0002] As people's requirements for car comfort continue to increase, seats, as an important part of car interiors, play a vital role. The personalized functions and overall comfort of seats have a significant impact on the experience and satisfaction of drivers and passengers. The personalized functions of seats include electric adjustment, massage function, heating and ventilation, etc. These functions can be adjusted according to the needs of drivers and passengers to provide a more comfortable sitting posture and support. At the same time, the overall comfort of seats also involves the selection of seat materials, ergonomic design, shock absorption and noise control, etc., to provide a stable, safe and comfortable driving environment. In order to ensure that the quality and performance of seats meet user requirements, the requirements of seat inspection tools are becoming more and more stringent. Seat inspection tools need to be able to perform various types of tests on seats, such as structural strength test, durability test, etc. Testing, ergonomic evaluation, etc. are used to verify the quality and performance of seats. As people pursue more comfort in cars and have higher requirements for personalized functions and overall comfort of seats, seat inspection tools also need to continuously adapt to market demand and provide more advanced and effective testing methods to meet users' requirements for seat quality and performance. However, the existing rear seat backrests are prone to movement during the bump and creep test. Unnecessary movement may occur during the test, affecting the accuracy and repeatability of the test data. The movement of the seat may cause uncontrollable variables in the test process. The change in seat position may interact with other factors, such as the vibration frequency of the vehicle, road conditions, etc., which will make the comparability and repeatability of the test results more difficult, thereby bringing uncertainty to seat design and evaluation. Therefore, those skilled in the art provide a rear seat backrest bump and creep tooling to solve the problems raised in the above background technology. Summary of the Invention
