Seat Bolster Design and Discomfort in Agricultural Equipment

Presented By: C. Matthew Hutmacher
This webinar will examine discomfort related to the design of seat bolsters in agricultural machinery and the scope of an upcoming research study on this topic. This is an under served segment, with little research quantifying the impact of seat bolsters. Learners will explore background information, study design, subjective measurements including the Automotive Seating Discomfort Questionnaire (ASDQ) and the Nordic Questionnaire, and objective measurements including pressure mean and max taken from a seat pan pressure map, and pressure gradient data.
At the completion of this activity, the learner will be able to:
Describe how seat bolster height and size may affect subjective user discomfort and pressure distribution
Recognize how bolster height and size may change response variables in people of different anthropometry
Discuss how rear-ward facing and angled driving situations may affect subjective user discomfort and pressure distributions
Identify the efficacy of pressure rating in predicting subjective comfort among users
