Abstract

A steering wheel unit for mounting on a steering column of a motor vehicle has a steering wheel including an inner frame with a steering wheel rim and with at least one spoke connected to the steering wheel rim and extending radially inwardly toward a steering column. The steering wheel includes a molded plastic envelope enclosing the inner frame. An air-bag anti-impact device is mounted on the steering wheel. A cap for covering the air-bag anti-impact device is provided. The air-bag anti-impact device has a folded air-bag and a gas producer for inflating the air-bag when tripped. The air-bag has a delimiting edge and is connected with the delimiting edge to the steering wheel to thereby delimit a gas inlet opening for gas produced by the gas producer upon tripping. The cap is opened by the force of the air-bag when being inflated by the gas producer. The molded plastic envelope and the cap are integrally formed so as to define a receiving area for the air-bag anti-impact device, wherein the air-bag anti-impact device is mounted within the receiving area.
