The wiper arm also includes a coil spring and a spring plate. The arm main body includes a hinge block rotatably connected to the arm head through a hinge pin and a shaft section extending from the hinge block. The spring plate includes a front end wall including an insertion hole into which the shaft section is inserted and leg sections rotatably attached to the arm head through a roller pin. The coil spring is disposed to be coaxial with the shaft section and is held to be sandwiched between the front end surface of the hinge block and the front end wall of the spring plate.

Abstract: The wiper blade-lifting system comprises a wiper arm with a motorized mechanism to cause the wiper blade to bend at a hinge point responsive to the presence of electrical power. The wiper blade-lifting system is useful to lift a wiper blade off the surface of a windshield when ice or freezing rain is anticipated, so that the wiper blade does not become frozen in place against the surface of the windshield. A second activation of the wiper blade-lifting system using electrical power of the opposite polarity causes the wiper blade to straighten and place the wiper blade back in contact with the windshield. The application of electrical power to the wiper blade-lifting system may be under control of an interior lift control or, in some embodiments, a blade lift remote control.

The tension arm has a tension arm head with a tension arm leg extending longitudinally therefrom. The tension arm head overlies the wiper arm head and the tension arm leg overlies the wiper arm. The tension arm head is coupled to the wiper arm head via a pair of arm members extending laterally therefrom. The arm members receive an anchoring screw therethrough which underlies the wiper arm head. The tension arm leg has a threaded hole therethrough receiving a wing screw which engages the wiper arm. Rotation of the wing screw serves to increase or decrease resilient pressure on the wiper arm.

Abstract: The compressor with variable pressure is equipped whit a head, fallowed by two arms equipped with a hole in there extremity, forming a 90 degree angle with the head of the compressor their giving them the possibilities to fallow each side of the head of supports of the windscreen wiper. So allowing by mean of one nut to anchor it after the head of support of the windscreen wiper and in this way to allow the compressor to fallow the same axis. Of a leg covering in is middle the leg of arm of support of the windscreen wiper, allowing the insertion of a nut with fin in a threaded hole situated at the end of the leg of the compressor. By turning the nut with fin downward, this gesture allows to pressurize the blade of the windscreen wiper, a pressure which obliges it to stick on the windscreen, allowing the blade to clean the windscreen with more efficiency. It eliminated the uprising of the blade induce by the strength of the wind or the speed of the car.
