OBJECTIVE Booster seat use among school-aged children has been consistently lower than national goals. In this study, we sought to explore associations between parental experiences with booster seats and carpooling. METHODS We conducted a cross-sectional Web-based survey of a nationally representative panel of US parents in January 2010. As part of a larger survey, parents of 4- to 8-year-old...

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...

OBJECTIVES To investigate the frequency and pattern of injury in front seat passengers as compared with drivers, in Scotland. METHODS Using the Scottish Trauma Audit Group (STAG) database from 1994 to 2000, a search for injuries to eight anatomical body regions was performed. Injuries were identified and selected by their abbreviated injury score code. A comparison of injury frequency between...

In many occupational and leisure environments, the human body is exposed to oscillatory motions of handles, seats and floors which give rise to complex patterns of sensations. Knowledge of differences in sensitivity to the perception of vibration at the hand, seat and foot would assist the identification of sources of discomfort caused by vibration. The objective of this study was to examine th...

Advancements in computer hardware in recent years have made it possible to solve complex real world problems using finite element methods (FEM). Full scale dynamic certification testing of aircraft seats is a very complex, expensive and time consuming process. A high acceleration pulse is applied on the seat structure in a short duration of period, and the seat structure has to pass stringent F...


 Abstract - From January 1, 2021 to June 30, 2021, the AIRBUS A330-200/300 aircraft belonging PT Garuda Indonesia has experienced 36 cases of damage business class seat. These most often occur due external factors on damaged by crew flight attendants as well technicians working. In study that discussed caused failure recline mechanism B/E Aerospace Minipod Seat and MCX Diamond Seat, then ...

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...

OBJECTIVES To investigate (1) the association of seat height and (2) the association of arm position on the five times sit-to-stand test (FTSTS) times of individuals with stroke. DESIGN A cross-sectional study. SETTING University-based rehabilitation centre. SUBJECTS Patients (n = 43) with chronic stroke. METHODS The times in completing the FTSTS with different seat height (85%, 100%, a...

INTRODUCTION Seat-belts are one of the most successful occupant protection countermeasures available to reduce the likelihood of death and non-fatal injury in the event of a crash. In Australia, the prevalence of seat-belt use by adult vehicle occupants is estimated to exceed 90%. Yet despite the effectiveness of seat belts and the comparatively high wearing rate in Australia, it is estimated t...
