Abstract: The seat comfort of commercial vehicle has always been a concern of seat designers and users. Starting from seat ride comfort, this paper introduces how to improve seat ride comfort in the design process by defining key dimensions of seat cushion and backrest, foam performance parameters, and checking operation space. Moreover, static and dynamic comfort evaluation is carried out on the first trial production sample chair, and whether the key dimensions and foam performance parameters of the seat need to be revised according to the evaluation results. Finally, it is pointed out that the design and test complement each other, improve the development efficiency of seat comfort, and avoid repeated changes in the later development work.

Key words: commercial vehicle seat; ride comfort; comfort evaluation; development efficiency
