Either a wheelchair user or caregiver is required to perform by hands raising and lowering of the footrests that the user puts feet on the operation. When the wheelchair user tries to walk in a state in which the footrests are not raised, there is a risk of falling and stumbled to the footrests. We have developed the footrests of a wheelchair with a spontaneously operative system. The footrests can be down easily by a foot of a caregiver or user before the operation. When the user is raising the feet for getting off the wheelchair, the footrests are spontaneously hopping up by means of repelling force of the spring and returning to the original position. It is easily installed in any commercial wheelchairs without special maintenance. As a result of trial in our hospital per year, it is expected operation, to obtain good evaluation by both users and caregivers. While it is currently patent pending, we want to aim to commercialization.
