Energy absorbing steering wheel
Abstract:
A steering wheel mounted on a hub. The steering wheel is molded of a high impact grade nylon and comprises an integral rim, spokes and a thin wall energy absorbing sleeve. The rim is disposed in coaxial relationship to and axially spaced from the hub.The energy absorbing sleeve when viewed in plan view has a substantially rectangular configuration of decreasing size from its upper end downwardly toward the hub. The walls of the sleeve have a generally ogival configuration from top to bottom. The construction and arrangement is such that the energy absorbing sleeve produces a large amount of crush at relatively constant load for obtaining a high degree of energy absorption.
