Based on that, caution needs to be exercised when using restraints or positioning belts. excursions in excess of the 15-inch SAE J2249 limit between 0-100 msec (Figure 5). Correct placement: The lap belt should be placed across the users hips, not across the abdomen or chest. This integrated restraint approach has been successfully implemented and has been shown to provide superior occupant protection in the automotive industry (10,11,12) and in school buses used to transport infants (13). For example: a. The comprehensive evaluation conducted in this study illustrates the occupant crash protection benefits of wheelchair-integrated restraint systems, as compared to vehicle-mounted restraint systems. Physical restraints and lap belts are also helpful for positioning people in their wheelchairs to reduce the risk of injury during wheelchair tips and falls.

Second, when attempting to install an occupant restraint anchor on a public transportation vehicle, it is common to find that the vehicle's structure dictates the use of an anchorage location that is less than optimal. with the 36-inch on-shoulder scenario. Caregivers can also push for periodic assessments to ensure the elder persons stability. Recently, WTORS manufacturers have begun offering "track-type" restraint anchoring systems that have been mounted longitudinally along van or bus walls, providing horizontal shoulder belt anchorage adjustment. :iuhS) KM (Where necessary to ascertain compliance with injury criteria or kinematic limits, time histories Fig. restraint system used in the model was either a vehicle-mounted lap and shoulder belt, or a fully government site.
