Abstract
Abstract A walker is disclosed in which the members supporting the seat of the walker are provided with a resilient material covering. The resilient covering material may be of tubular construction thereby enabling it to be mounted on the seat supporting members by sliding it over such members. Alternatively, the resilient covering material may be in sheet form and mounted around the supporting members by wrapping it thereon. In such a case, the resilient material would be held in place by a covering material provided with fastening means, straps, adhesive or other suitable means. The resilient material is preferably a foam type of material and preferably extends downward over at least the outer portions of the wheels of the walker. The purpose of the above abstract is to provide a non-legal technical statement of the disclosure of the contents of the instant patent application and thus serve as a searching-scanning tool for scientists, engineers and researchers. Accordingly, this abstract is not intended to be used in understanding or otherwise comprehending the principles of the present invention hereinafter described in detail, nor is it intended to be used in interpreting or in any way limiting the scope or fair meaning of the claims appended hereto.
