摘要：
A backboard includes a body that has length that is sufficient for extending under a person. The body further has an upper side for supporting a person thereon and a lower side for resting on a generally flat surface, with the body forming multiple pivot points between the upper side and the lower side. The body supports a movable contact surface to provide lateral support to and increase the contact area between the backboard and the person supported thereon.
