Abstract
Abstract A steering wheel for an automobile including a brittle plastic impact energy absorber disposed on a boss assembly. The absorber is held in a wheel pad by brackets having a front connector and a rear connector. The front connector is engaged with the front edge of a boss plate, and the rear connector with a wall portion of the main body of the steering wheel or with a support provided in the boss assembly. This engagement is easy to achieve reliably only if the wheel pad is forced down into the boss assembly.
