Head rest sleeve

摘要: A head rest sleeve for receiving a support rod having diameter within known tolerance range is formed of resilient material and has body an axial bore. Integral with the inside disposed thereabout are at least two pairs compressible crush ribs which protrude radially extend length body. The distance protrusion corresponds to minimum possible rod. Located between each pair integral therewith web protrudes corresponding maximum When inserted into sleeve, frictionally engages uniformly along its and, when greater than diameter, compresses uniform allow be moved in sleeve. compressed such that webs as well ribs. In this manner tight friction fit guaranteed regardless actual
