1,177,122. Arm rests, handles. SPARTAN PRODUCTS Inc. 12 Jan., 1967 [24 Jan., 1966], No. 1700/67. Headings A4J and A4U. [Also in Division B7] An armrest or handle comprises, a cellular member 12 of polyethlene plastics material having vertical cell walls, a loose covering sheet material 34, polyurethane foam filler 14, and a vinyl cover or casing 10. The cells may have tapering walls as in Fig. 5 to provide an increasing resistance to lateral deformation, or different size cells as in Fig. 6 to provide the same effect, but the cells extend clear through the member 12. A lengthwise slit 22 is provided in the casing 10 so that in manufacture the member 12 may first be pushed into the casing, the filler 14 in liquid form may then be introduced into the casing through slit 22 and holes 36 and the liquid then foamed and expanded to enclose the member 12 protected by the cover 34. Vent and overflow holes may be provided, although the holes 36 may themselves, serve this purpose.
