Abstract

A windshield wiper device, in particular for a motor vehicle, comprising a carrier (12) for fixing to a first part (52), especially to the body of the motor vehicle. A locking element (40) having a predetermined breaking point (41) is also provided in order to enable the carrier (12) to be fixed to the first part (52) by a rotational connection.

Claims

1. Windshield wiper device, for a motor vehicle, comprising a carrier (12) for fixing to a first part (52), and a locking element (40), which enables the carrier (12) to be fixed to the first part (52) by means of a rotational connection, characterized in that the locking element (40) has a predetermined breaking point (41), characterized in that the locking element (40) features a first section (42), which is longer in cross section than it is wide, and the predetermined breaking point (41) is arranged in the first section (42), and characterized in that the first section (42) has a transverse groove (48) to accommodate the first part (52).

2. Windshield wiper device according to claim 1, characterized in that the rotational connection has a catch (58) to lock the locking element (40) so that a rotational/locking connection is formed.

3. Windshield wiper device according to claim 2, characterized in that the carrier (12) has an opening (22) and that the locking element (40) in a closed state penetrates the opening (22).

4. Windshield wiper device according to claim 3, characterized in that a minimum of one, at least partially elastic damping bushing (36, 38) is arranged between the locking element (40) and opening (22).

5. Windshield wiper device according to claim 4, characterized in that first section (42) is elliptical in cross section.

6. Windshield wiper device according to claim 5, characterized in that the width (B) of the transverse groove (48) is greater than the thickness D of the first part (52).

7. Windshield wiper device according to claim 6, characterized in that the first part (52) is embodied as a stamped part or stamped bent part and features a hole (54) having the shape of the first section (42) of the locking element (40).

8. Windshield wiper device according to claim 7, characterized in that the locking element (40) penetrates the first part (52) and the first part (52) features a slant (56) of such a type that the locking element (40) is pulled into the first part (52) during the closing process.

9. Windshield wiper device according to claim 8, characterized in that the locking element (40) has an engagement (50), which enables it to cooperate with a tool.

10. Windshield wiper device according to claim 1, characterized in that the carrier (12) has an opening (22) and that the locking element (40) in a closed state penetrates the opening (22).

11. Windshield wiper device according to claim 10, characterized in that a minimum of one, at least partially elastic damping bushing (36, 38) is arranged between the locking element (40) and opening (22).

12. Windshield wiper device according to claim 1, characterized in that first section (42) is elliptical in cross section.

13. Windshield wiper device according to claim 1, characterized in that the width (B) of the transverse groove (48) is greater than the thickness D of the first part (52).

14. Windshield wiper device according to claim 1, characterized in that the first part (52) is embodied as a stamped part or stamped bent part and features a hole (54) having the shape of the first section (42) of the locking element (40).

15. Windshield wiper device according to claim 1, characterized in that the locking element (40) penetrates the first part (52) and the first part (52) features a slant (56) of such a type that the locking element (40) is pulled into the first part (52) during the closing process.

16. Windshield wiper device according to claim 1, characterized in that the locking element (40) has an engagement (50), which enables it to cooperate with a tool.

17. Windshield wiper device according to claim 1 wherein the first part is connected to a body of the motor vehicle.
