Abstract
Abstract The attachment comprises two U-shaped tubular members joined at their open ends and offset from each other by an adjustable obtuse angle. Material providing a head rest is secured to one of the U-shaped members adjacent its closed end and a non-skid material is applied to the closed end of the other U-shaped member. The ends of the other U-shaped member are offset at an angle to facilitate insertion into the tubular handles of a wheelchair. With the attachment secured to the wheelchair, the chair can be tipped backwards and is supported by the closed end of the other U-shaped member. Two additional straps extend about the one U-shaped member below the head rest to support the upper back of the wheelchair occupant.
