Abstract

The invention provides a cover of a driver-side gas bag collision protection device accommodated in the steering wheel in motor vehicles. The cover comprises two cover portions which are each secured to a housing accommodating the gas bag collision protection device via an outer edge region permitting the cover portions to fold open and are connected together at their center edge region along a tear line by weakened wall portions. Each cover portion comprises a reinforcing insert embedded in foamed plastic. The reinforcing insert is formed by a metal plate, preferably of aluminium, and extends out of the outer edge region of each cover portion and terminates in lug-like securing portions.
