Steering wheel

摘要

A steering wheel has a gripping formation including an armature substantially encapsulated by a cover of foamed material and a flexible outer skin provided over and around the cover. The flexible skin may be formed of leather or artificial leather. The steering wheel may include a plastic insert engaged within a fixing groove or recess formed in the cover. At least one edge of the outer skin may be positioned within the fixing groove or recess and fixed to the insert by ultrasonic welding, for example. In a preferred arrangement, two opposed edges of the outer skin may be both received within the fixing groove or recess and fixed to the insert therein by ultrasonic welding.
