A correct seat and position are the basis for a good performance in horseback riding. This study aimed to measure deviations from the correct seat, test a seat improvement program (dismounted exercises), and investigate whether horse behavior was affected by the rider's seat. Five experienced trainers defined 16 seat deviations and scored the occurrence in 20 riders in a dressage test. Half the...

This study finds that the break-even point for child safety seat misuse reduction programs and vehicle and seat design improvements is dollars 121 a year per child seat in use, annual misuse reduction program cost is dollars 6, and Lower Anchors and Tethers for Children (LATCH) cost dollars 13 annually per seat in use (in 2004 dollars). To estimate societal injury cost savings we compared tow-a...

field study was conducted to evaluate seat designs on shuttle cars. Eight operators R A participated in evaluating seat designs on the basis of perceived levels of vehicle jarring/jolting and discomfort. Researchers also measured the levels of vehicle jarring/jolting. Four basic seat designs were compared on low and mid-coal seam shuttle cars during production operations at two underground coal...

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 ...

Car seat heaters have gained popularity in America and worldwide. They offer comfort by heating the sitting surface to a soothing temperature. Several cases of heating-element malfunction resulted in burn injuries and have triggered recalls of thousands of cars by the manufacturers. We present a case of a 48-year-old patient with long-standing paraplegia who sustained third-degree burns on his ...

Lateral acceleration causes discomfort but how the discomfort depends on the frequency of acceleration or characteristics of seating is poorly understood. Using magnitude estimation, twelve male subjects rated the discomfort caused by lateral oscillation at eight frequencies (0.2-1.0 Hz) across four seating conditions (a rigid seat and a train seat, both with and without backrests). Discomfort ...

The objective of this study was to explore the effect of a forward sloping seat on posture and muscular activity of the trunk and lower limbs. To this aim, twelve asymptomatic participants were tested in six conditions varying seat slope (0°, 15° forward) and height (high, medium, low). Angular position of head, trunk and pelvis was assessed with an inertial orientation system, and muscular act...

A hybrid system for detecting driver drowsiness was examined by using piezofilm movement sensors integrated into the car seat, seat belt and steering wheel. Statistical associations between increase in the driver drowsiness and the non-invasive and conventional physiological indicators were investigated. Statistically significant associations were established for the analysed physiological indi...

Sixty elementary schools in Minneapolis were asked to participate in a study to evaluate the most effective education method to increase booster seat knowledge and use in kindergarten-age children. School personnel selected one of the following interventions: (1) written information, (2) parent education class and a free booster seat, or (3) student education and a free booster seat. Twenty sch...

Operators of agricultural machinery are exposed to an extensive range of indirect vibrations through the seats, which gradually causes chronic damages. One of the ways to reduce the vibrations imposed on the operators is to use appropriate materials in tractor seat cushion. The present study was carried out in order to select appropriate foam or sponge and investigate different factors in reduc...
