Abstract

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).

Description

technical field [0001] The invention relates to a wiper arm for a windshield wiper device of a motor vehicle, the wiper arm having a first fixing seat for fixing the wiper arm on the windshield wiper device and a A second fastening seat for a water blade, wherein a rigid wiper arm region adjoining the first fastening seat and a resilient wiper arm region adjoining the second fastening seat are arranged between the first and second fastening seats. wiper arm area, wherein the rigid wiper arm area is designed to transmit the torque of the wiper arm loaded about the axis of rotation and the elastic wiper arm area is designed to provide The force with which the sheet is pressed against the windshield.
