Description

Technical Field

[0001] This invention relates to the field of vehicle seat evaluation technology, and in particular to a seat comfort evaluation fixture. Background Technology

[0002] With the trend of upgrading in automobile consumption, the demand for cars has increased significantly, and there are also higher requirements for cars, reflected in aspects such as safety, aesthetics, and comfort. Passenger car seats are gradually evolving from functional to consumer-oriented, and seat comfort is one of the important evaluation indicators for car use.

[0003] Traditional seat comfort assessment activities, which use vehicle body fixtures or flatbed fixtures for static evaluation, have drawbacks. Using vehicle body fixtures for static comfort assessments means that the fixtures are not interchangeable for different seats on the same frame platform. Simultaneous assessment of multiple projects requires multiple vehicles, which, due to their large size and weight, places high demands on the assessment site, causing numerous inconveniences. Using flatbed fixtures for static comfort assessments results in inaccurate seat comfort perceptions because the fixtures do not match the actual vehicle environment. Furthermore, the fixtures do not support adjustments to some seat parameters, hindering design verification. These problems urgently need to be addressed. Utility Model Content
