Abstract

The wheelchair attachments are configured for removable attachment to a wheelchair to facilitate use of the wheelchair by occupants and/or attendants. One attachment is a retractable tray spanning the armrests at the front of the chair when deployed and retracting between the chair structure and a wheel for storage. Another attachment is a series of interchangeably installable handgrips or handles removably installable to the front or back of the chair for use by an attendant. At least some of the various handgrips or handle assemblies provide horizontal and/or vertical adjustment. Yet another attachment is an underseat storage compartment, primarily accessible by an attendant from the back of the chair. All of the various attachments may be installed upon and/or used with a wheelchair independently of one another or in combination with one another, or may be adapted for use with other devices as well.
