Windshield wiping device for a motor vehicle
First Claim
1. Windshield wiper device for a motor vehicle with at least one molded tube (10, 20) to accommodate a drive shaft to drive at least one wiper arm, wherein the at least one molded tube (10, 20) is attached to a holding element (11, 21) that is connectable to a body, and to a stub (12, 22) accommodating a mounting plate tube, whereby at least first and second connecting bridges (14, 15, 23, 24) are provided to attach the at least one molded tube (10, 20) to at least one of the holding element (11, 21) and the stub (12, 22), whereby an impact force (F) acting on the at least one molded tube (10, 20) and therefore on the connecting bridges (14, 15, 23, 24) is strengthened by a lever arm design, whereby the first and second connecting bridges are formed so that the first connecting bridge tears first before the second connecting bridge tears as a result of the impact force, and wherein the second connecting bridges (15) form elbow levers, each defining an elbow secured to one side of the at least one tube with the respective connecting bridges extending therefrom substantially along the one side, the connecting bridges having a length thereof from a respective elbow to the attachment with the holding element or stub, a substantial portion of the length having an entire periphery free from contact with the tube, the holding element and the stub, the substantial portion of the length having a substantially uniform transverse cross-section.

- 1. Windshield wiper device for a motor vehicle with at least one molded tube (10, 20) to accommodate a drive shaft to drive at least one wiper arm, wherein the at least one molded tube (10, 20) is attached to a holding element (11, 21) that is connectable to a body, and to a stub (12, 22) accommodating a mounting plate tube, whereby at least first and second connecting bridges (14, 15, 23, 24) are provided to attach the at least one molded tube (10, 20) to at least one of the holding element (11, 21) and the stub (12, 22), whereby an impact force (F) acting on the at least one molded tube (10, 20) and therefore on the connecting bridges (14, 15, 23, 24) is strengthened by a lever arm design, whereby the first and second connecting bridges are formed so that the first connecting bridge tears first before the second connecting bridge tears as a result of the impact force, and wherein the second connecting bridges (15) form elbow levers, each defining an elbow secured to one side of the at least one tube with the respective connecting bridges extending therefrom substantially along the one side, the connecting bridges having a length thereof from a respective elbow to the attachment with the holding element or stub, a substantial portion of the length having an entire periphery free from contact with the tube, the holding element and the stub, the substantial portion of the length having a substantially uniform transverse cross-section.
- 13. Windshield wiper device for a motor vehicle with at least one molded tube to accommodate a drive shaft to drive at least one wiper arm, wherein the at least one molded tube is attached to a holding element that is connectable to the body, characterized in that the holding element features a cross-section reduction in the area of the attachment of the at least one molded tube to the holding element, whereby the molded tube is connected by at least first and second connecting bridges to the holding element, whereby the first and second connecting bridges are formed so that the first connecting bridge tears first before the second connecting bridge tears, and wherein the second connecting bridges (15) form elbow levers, each defining an elbow secured to one side of the at least one tube with the respective connecting bridges extending therefrom substantially along the one side, the connecting bridges having a length thereof from a respective elbow to the attachment with the holding element or stub, a substantial portion of the length having an entire periphery free from contact with the tube, the holding element and the stub, the substantial portion of the length having a substantially uniform transverse cross-section.
- 17. A windshield wiper device for a motor vehicle with at least one molded tube for receiving a drive shaft adapted to drive at least one wiper arm, the molded tube being attached to a holding element that is connectable to a body, and the molded tube being attached to a stub connectable to a mounting plate tube, the molded tube being attached to the holding element and to the stub by first and second connecting bridges formed so that in the event of an impact force the first connecting bridge tears first before the second connecting bridge tears, wherein the impact force is strengthened by a lever arm design of a connecting lever, and wherein the connecting bridges are formed as elbow levers, each defining an elbow secured to one side of the at least one tube with the respective connecting bridges extending therefrom substantially along the one side, the connecting bridges having a length thereof from a respective elbow to the attachment with the holding element or stub, a substantial portion of the length having an entire periphery free from contact with the tube, the holding element and the stub, the substantial portion of the length having a substantially uniform transverse cross-section.
