Abstract

This invention discloses a back rest, including a body member formed with a back-facing side to face the back of a user, and a plurality of spaced projections projecting from the back-engageable face to engage the back of user at a plurality of discrete points, each of the projections being stiff, formed with a rounded outer surface to contact the user'"'"'s back, and circumscribed by a relatively flat surface, such that the projections produce a Shiatsu local massaging effect on the user'"'"'s back.

Claims

1. A back rest comprising:

a plurality of discrete elements, each having a uniform thickness and defining at least one edge;

a multiplicity of mutually spaced protrusions integrally formed with said discrete elements and having said uniform thickness, extending outwardly at said at least one edge; and

a combination joining and covering element comprising a portion of semi-flexible web material having apertures therein, said web material tightly engaging said plurality of discrete elements, whereby said apertures are stretched over said protrusions, said protrusions extend through said apertures, and retaining said plurality of discrete elements in generally parallel registration.

2. A back rest according to claim 1 and also comprising a plurality of spacer elements having a configuration similar to said plurality of discrete elements but lacking at least some of said multiplicity of protrusions, at least one of said spacer elements being disposed intermediate each pair of said plurality of discrete elements.
