The performance of a product depends on if it is created in terms of expected functional requirements. A product is designed to satisfy some certain tasks. In this study, the design of an automobile seat is handled. Automobile seat design procedure is based on experience and trial-and-error method, rather than structured and scientific methods. Axiomatic design is a design theory providing a sy...

Sonarmen undergoing refresher training in the Sonar Operational Trainer compared, while on "sonar watch," the comfort of four seating designs: a contoured automobile seat with an adjustable backrest; a "kneeling" chair; a conventional office chair with an inflatable lumbar support pillow; and a conventional office chair. The subj ects were asked to use each seat for an entire day --unless it wa...

The purposes of this study were to determine which seat features/occupational demands contributed to police officer discomfort and whether an automobile seat fitted with an active lumbar system (ALS) could reduce driving discomfort. Fifty-eight officers were given questionnaires to assess driving discomfort. High discomfort levels were associated with computer use, duty belt, sidearm/radio, bod...

A growing issue in the area of vehicular ride comfort is that of child safety seats. Postural, thermal and vibrational comfort considerations are finding their way into child seat design. This paper makes some observations regarding the current state of child safety seat design, then goes on to present the results of vibration tests performed over two road surfaces using two child seats and two...

Along with recent advancement, many automobile industries have strongly encouraged research on their product design, structure, consumer comfort and ergonomics and so on. In particular, consumer satisfaction or human comfort is playing an important role including seat comfort, driving posture, visibility, interior space, etc., In general, sitting in an automobile seat for prolonged period can c...

Blunt chest trauma is a rare cause of aortic valve dysfunction. A case of the successful management of traumatic injury to the aortic valve is reported. The aortic valve injury was sustained in an automobile accident despite the use of a seat belt and the deployment of an air bag. The literature is briefly reviewed. Aortic valve injury remains a consideration in cases of automobile-associated c...

− Seat occupancy detection systems based on a capacitive or an electric field principle, developed for an automobile seat, may not work well for seats with integrated electric heating systems. A new detection method, suitable for this type of automobile seats, is presented in this paper. In the proposed scheme, the heating element is a part of the sensor system while its operation as a heating ...

Comfort on automobile seats is lived daily by thousands of drivers. Epistemologically, comfort can be understood under the theory of complexity, since it emerges from a chain of interrelationships between man and several elements of the system. This interaction process can engender extreme comfort associated to the feeling of pleasure and wellbeing or, on the other hand, lead to discomfort, nor...
