Improvements in passenger compartment comfort continue to be one of the key needs of the global transportation industry. Since their introduction more than 40 years ago, flexible molded polyurethane foams have successfully contributed to the comfort provided by all forms of transportation seating. Initially required to provide just a wide range of load bearing, seating foams are now being desig...

AIMS: Pressure injuries (PIs) are common issues that can be minimized through the use of pressure-redistributing support surfaces. Cushions provide immersion and contour considered most effective for pressure relief; however, others readily available on market. The aim this study is to determine how a wheelchair equipped with Comfort Tension Seating®(CTS) compares standard sling seating...

background: seat belts have been proven as one of the most successful means of preventing or reducing injuries to occupants of cars during an accident. this paper examines the reasons behind the non-compliance of the seat belt law in malaysia and suggests possible measures to get the percentage of seat belt usage up higher. methods: various databases of articles were searched for seat belt usag...

Bone tissue engineering may provide an alternative to autograft, however scaffold optimisation is required to maximize bone ingrowth. In designing scaffolds, pore architecture is important and there is evidence that cells prefer a degree of non-uniformity. The aim of this study was to compare scaffolds derived from a natural porous marine sponge (Spongia agaricina) with unique architecture to t...

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...

OBJECTIVE To investigate the effects of body mass composition and cushion type on seat-interface pressure in spinal cord injured (SCI) patients and healthy subjects. METHODS Twenty SCI patients and control subjects were included and their body mass composition measured. Seat-interface pressure was measured with participants in an upright sitting posture on a wheelchair with three kinds of sea...

The technique of interface pressure measurement has generated considerable interest in the automotive industry as a method, which could be used to predict driver discomfort during the development of prototype seat designs. Two repeated measures experiments were carried out to evaluate the practical application of the technique. The variables of foam density and posture were used to create disco...

Background: Sponge bezoars will absorb luminal contents, enlarge, and subsequently harden. There is significant potential for the development of intestinal obstruction and perforation. Methods: We report the case of an unsuspected polyurethane foam (PUF) sponge bezoar causing intestinal obstruction in an 8-year-old boy undergoing laparoscopy for an ingested lithium battery that was adherent to ...

The seat of a construction machinery cab is used as the research object. For current human-seat coupling system comfort methods and optimization index deficiencies, body pressure vibration at same time optimized. Based on more specialized Toyota 50 percentile dummy model, finite element simulation model established, distribution response are simulated calculated. transverse longitudinal distrib...

Nowadays, riding comfort is more significant than before for evaluating the quality of high–speed railways and sitting most common posture its passengers. This study aimed to analyze optimize pressure distribution second–class seats with different design parameters. Firstly, 21 features were calculated after field tests conducted on a CRH Train. The subjective was quantified as linear combinati...
