ABSTRACT:
The disclosed invention relates to a force-absorbing member which is formed of a resilient plastic material having a relatively high tensile strength mounted in a suitable restraining member. The force-absorbing member includes an annular mounting flange which is of sufficient size and the material of the force-absorbing member of sufficient strength to permit the force-absorbing member to readily deflect to one side of its axis during use, and the mounting of the flange is such that the flange will not rupture or pull through the member restraining it against movement. The force-absorbing member may be utilized, inter alia, as a bumper per se, as a support for a bumper, as a combined boat rub-rail and line-attaching member, or as part of a shock-absorbing unit of a tow unit, such as a tow chain.
