    • The invention relates to a wiper arm (1) for a windshield wiping device (3) of a motor vehicle, comprising a first receiving portion 9 for fixing the wiper arm (1) on the windshield wiping device (3) and a second receiving portion (10) for fixing a wiper blade (2). A rigid wiper arm region (13) that adjoins the first receiving portion (9) and an elastic wiper arm region (14) that adjoins the second receiving portion (10) lie between the first and second receiving portions (9, 10). The rigid wiper arm region (13) is designed to transmit a torque that acts about a rotational axis (24) of the wiper arm (1) and the elastic wiper arm region (14) is designed to provide a force to push the wiper blade (2) onto a windshield. The rigid wiper arm region (13) has a first insert (15) and the elastic wiper arm region (14) has a second insert (16), said first insert (15) being surrounded by a first plastic casing (17) and said second insert (16) being surrounded by a second plastic casing (18). The first plastic casing (17) has an elasticity that is different from the second plastic casing (18).
    • 本发明涉及一种用于机动车辆的挡风玻璃刮水装置(3)的刮水臂(1),该刮水臂包括用于将刮水臂(1)固定在挡风玻璃刮水装置(3)上的第一接收部分9和用于将刮水臂 (10),用于固定刮水片(2)。 邻接第一容纳部分(9)的刚性刮水臂区域(13)和邻接第二容纳部分(10)的弹性刮水臂区域(14)位于第一容纳部分和第二容纳部分(9,10)之间。 刚性刮水臂区域(13)被设计成传递围绕刮水臂(1)的旋转轴线(24)作用的扭矩,并且弹性刮水臂区域(14)被设计成提供用于推动刮水片 (2)到挡风玻璃上。 所述刚性刮水臂区域13具有第一插入件15并且所述弹性刮水臂区域14具有第二插入件16,所述第一插入件15由第一塑料壳体17包围, 第二插入物(16)被第二塑料外壳(18)包围。 第一塑料外壳(17)具有与第二塑料外壳(18)不同的弹性。
