The invention relates to a steering wheel for a motor vehicle, comprising a steering wheel body (2) which has an inner steering wheel core (1) and at least one groove (4) which is formed in the steering wheel body (2) and which surrounds the circumference, said groove having a groove base (4c) and groove side walls (4b) for receiving free ends (3a, 3b) of a strip of a covering (3) in a stationary manner. In the steering wheel main body (2), a barb (5c) which extends into the groove (4) and points to the bottom of the groove is arranged on the side wall (4b) of the groove. According to a method for producing such a steering wheel by means of a forming tool (6), a circumferential projection (6a), which defines the shape of the recess (4), is provided in the forming tool (6) in order to produce at least one recess (4) in the steering wheel body (2). A required number of fastening clips (5, 8) are placed on the projections (6a) while being held in the region of the barbs (5c) by the tension forces thereof. The steering wheel core (1) is then wrapped with a suitable material and, after wrapping the steering wheel core (1), the steering wheel body (2) is separated from the forming tool (6), the fastening clips (5, 8) being pulled away from the projections (6a) and projecting into the recess (4) by means of the spring force thereof with barbs (5c) through the side walls of the recess (4). As a result, the ends (3a, 3b) of the sheath (3) are reliably prevented from sliding out of the recess (4).

    一种用于机动车辆的方向盘,具有方向盘主体(2),方向盘主体(2)具有内部的方向盘芯(1)以及至少一个构造在方向盘主体(2)中的、在圆周上环绕的凹槽(4),所述凹槽具有凹槽底部(4c)以及凹槽侧壁(4b),用于位置固定地接纳覆皮(3)的条带的自由端(3a、3b),其特征在于,在方向盘主体(2)中,在凹槽侧壁(4b)上设置有伸入凹槽(4)并指向凹槽底部的倒钩(5c)。根据用于借助成型工具(6)制造这种方向盘的方法,在成型工具(6)中为了在方向盘主体(2)中制造至少一个凹槽(4)而设置有规定出凹槽(4)的形状的、环绕的突起(6a)。所需数量的紧固夹(5、8)在通过其张紧力保持在倒钩(5c)的区域中的情况下,被放置到突起(6a)上。然后用合适的材料包裹方向盘芯(1),并且在包裹住方向盘芯(1)后,方向盘主体(2)与成型工具(6)分离,其中,将紧固夹(5、8)与突起(6a)拉开,并通过其弹簧力以倒钩(5c)穿过凹槽(4)的侧壁伸入到凹槽(4)中。由此可靠地防止覆皮(3)的端部(3a、3b)从凹槽(4)中滑出。
