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. By doing so, you can help prevent injuries, ensure optimal safety, and enjoy greater peace of mind. Regular inspection: The lap belt should be inspected regularly for signs of wear or damage, and should be replaced as needed to ensure optimal safety. That is, head excursion could be given greater weighting than knee excursion because secondary head impact with the vehicle interior would present a greater risk of severe injury than impact of the knee with the vehicle interior. However, when used improperly or in ways other than intended, injury or even death can result. Lap belts on wheelchairs might seem like a good idea in terms of the safety of an elderly person, but sometimes these seatbelts can become a nuisance and even a danger, especially if they are not used properly. hbbf`b``3 - Register to receive personalised research and resources by email. Application of this anchoring configuration by wheelchair users of a size other than the 50th-percentile male can be ineffective or even hazardous to the occupant if the belt transmits forces to body areas other than boney structure.

You can opt out or change your mind by visiting: http://optout.aboutads.info/. Because most wheelchairs were not designed for this purpose, the wheelchair-seated occupant is not offered the same level of safety as those occupants using automotive original equipment manufacturers (OEM) vehicle seats. Based on that, caution needs to be exercised when using restraints or positioning belts. Comparison of modified MC versus MC index for varying restraint scenarios. 0000000016 00000 n H\j0~ In addition to causing a delay in the vehicle route schedule, this restraint engagement process usurps the independence of the wheelchair user. PMC Also, this approach removes the complexity associated with attempting to fit a vehicle-mounted occupant restraint to the wide range of occupant-wheelchair size combinations. The HIC values were calculated for each restraint scenario in terms of occupant response, since the shoulder slips free of the shoulder belt, allowing for Voluntary standards have been developed to establish general design and performance requirements for wheelchairs intended to be used as a vehicle seat (i.e., transport-safe wheelchairs), and for wheelchair tiedowns and occupant restraint systems (WTORS).

Skin injuries: If the lap belt is too tight, it can cause skin irritation, pressure sores, or even cuts on the occupants skin. Before choosing a lap belt, it is important to consult with a healthcare professional, such as a physician, physical therapist, or occupational therapist, to ensure that you select the appropriate type of belt for your specific needs. The integrated restraint scenario resulted in a peak knee excursion of 2.5 inches.

Our findings replicate those of Wainwright and Johnson Controls, with the wheelchair integrated restraint scenario producing the lowest on-shoulder HIC value and chest acceleration. Furthermore, occupant restraint systems used by vehicle-seated occupants have been designed to accommodate and provide effective protection to a diverse population of able-bodied occupants. With a contagious smile and a heart of gold, Ryan uses his expertise to empower caregivers and make their journey a little bit easier and more fun. Individual body regions considered in the CIC index are also weighted based upon their injury significance derived from accident statistical studies (19). New York: Springer Verlag, 1993. p. 319-22. The idea of using restraints to help prevent falls in older adults who are wheelchair-bound is a controversial one. Through the use of wheelchair integrated restraints, the fit of the lap belt will inherently be customized to each individual wheelchair user, because wheelchair prescription is dependent upon occupant size. Figure 8. %%EOF With the exception of an unsafe 36" height off-shoulder shoulder belt anchor scenario, the MC index was minimized for the integrated restraint scenario. The purpose of this study was to conduct a review of available literature from 1966-2006 to identify the risks and benefits associated with lap belts while seated in wheelchairs. Lap belts on wheelchairs might seem like a good idea in terms of the safety of an elderly person, but sometimes these seatbelts can become a nuisance and even a danger, especially if they are not used properly. technology to the wheelchair transportation industry. Similarly, the CIC index was also minimized for the wheelchair-integrated restraint scenario. At the very least, they pose a safety hazard. Unfortunately, achieving this belt fit in wheelchair transportation scenarios using a fixed anchor, vehicle-mounted restraint system is difficult to attain across a mixed occupant population having varying wheelchair seat heights. 0000006914 00000 n

Webwheelchair user and their care provider must collaborate to reduce risks in transport to the lowest possible level. Kang W, Pilkey W. Crash simulations of wheelchair occupant systems in transport. 940218, 1994. If the CIC index and the MC index were to be combined into one index then it is necessary that the appropriate weighting be applied (i.e., the modified MC index) so as to not dilute those scenarios that produce occupant responses that exceed injury criteria or limits. This assessment should take into account several factors, including the users physical condition, level of mobility, and any underlying health issues.

Previous studies, such as by Wainright and others, of integrated restraint systems used with OEM vehicle seats have shown reduced HIC values and lower chest accelerations as compared to vehicle-mounted restraint systems (11). If you or a loved one uses a wheelchair, take the time to assess the risks associated with lap belt use and to ensure that the lap belt is being used properly.
