This paper presents an optimal vehicle and seat suspension design for a half-car vehicle model to reduce human-body vibration (whole-body vibration). A genetic algorithm is applied to search for the optimal parameters of the seat and vehicle suspension. The desired objective is proposed as the minimization of a multi-objective function formed by the combination of seat suspension working space ...

Overall seating comfort is influenced by both static and dynamic characteristics of seat system. Therefore, the present study is an overview of work related to comfort in seat-operator interface affected by static and dynamic pressure distribution, and other related parameters involved in seat comfort, low back pain, seat design and safety in seats. A critical review has been presented on the s...

[Purpose] We assessed the effects of a suspension seat support chair on the trunk flexion angle and gluteal pressure during computer work. [Subjects] Ten males were recruited. [Methods] The suspension seat support was developed to prevent abnormal gluteal pressure and a slumped sitting posture during computer work. The gluteal pressure was measured with a TekScan system and the trunk flexion an...

Today numerous car seat models are available in the market but no car seat is actually satisfying customer needs to satisfactorily level. In fact customers comprise with available car seats. By considering this factor this paper mainly concentrated on the human comfort. This research papers helps to understand the current seat problems and its recommended solutions. This paper proposes a neuro ...

OBJECTIVE Injuries sustained in motor vehicle accidents (MVAs) are a major challenge to the Jamaican healthcare system. In November 1999, Jamaica enacted legislation to make seat belt usage in motor vehicles compulsory. The effect of this policy change on seat belt usage is unclear. This study therefore sought to determine the prevalence of seat belt usage and to determine the association betwe...

The vibration characteristics of car seats directly influence the ride comfort. Polyurethane foam is key part a seat, and its physical parameters have an important impact on seat. In this study, thickness hardness seat cushion with different excitation magnitudes was investigated by using transmissibility effective amplitude (SEAT) value. First, tests were carried out at vertical simulator widt...

STUDY OBJECTIVE We assess the relationship between steering wheel deformity and serious thoracic or abdominal injury among drivers and front seat passengers involved in motor vehicle crashes, while adjusting for important crash factors. METHODS This was a national population-based cohort of adults involved in motor vehicle crashes from 1995 to 2002 and included in the National Automotive Samp...

Of 2,275 cases of non-fatal injuries sustained by all categories of road users 185 were inflicted on back seat passengers. Twenty-six such passengers sustained severe and 66 moderately severe injuries. Only two patients (aged 18 months and 3 years) wore any form of restraint. Back seat passengers may be injured by impact with the rear of the front seat or other objects in the rear compartment; ...

To study the effect of seat height on the cardiorespiratory system and kinematics in handrim wheelchair ambulation, nine non-wheelchair users participated in a wheelchair exercise experiment on a motor-driven treadmill. The subjects conducted five progressive exercise tests. After an initial try-out test, four tests were performed at different standardized seat heights of 100, 120, 140, and 160...

When designing wheelchairs for use as motor vehicle seats, special design criteria must be followed to assure the crash safety of the wheelchair user. Failure of seating system components under crash loading conditions could lead to serious injury or fatality. In this study, seat and seat-back loading in a frontal crash are explored using computer simulation techniques. A previously validated s...
