Abstract
A wiper blade apparatus with at least one spring strip having at least one wiper strip unit, which comprises at least one wiper lip and at least one wiper base body, which bounds at least one recess to a receptacle of the at least one spring strip and at least one damping cavity that is separate from the recess, and having at least one wind deflector unit, which at least partially overlaps with the wiper base body of the wiper strip unit and which comprises at least two guide bars, which extends to both sides of the wiper base body. It is proposed that the wiper strip unit comprise at least one resilient support elements arranged on the wiper base body and supported between the wiper base body and at least one of the guide bars.
Claims18
A wiper blade apparatus with at least one spring strip (12a, 12a′;
- 12b, 12b′), having at least one wiper strip unit (14a;
- 14b), which comprises at least one wiper lip (16a;
- 16b) and at least one wiper base body (18a;
- 18b), which bounds at least one recess (20a;
- 20b) to a receptacle of the at least one spring strip (12a, 12a′;
- 12b, 12b′) and at least one damping cavity (22a;
- 22b) that is separate from the recess (20a;
- 20b), and having at least one wind deflector unit (24a;
- 24b), which at least partially overlaps with the wiper base body (18a;
- 18b) of the wiper strip unit (14a;
- 14b) and which comprises at least two guide bars (26a, 26a′;
- 26b, 26b′), which extends to both sides of the wiper base body (18a;
- 18b), wherein the wiper strip unit (14a;
- 14b) comprises at least one resilient support element (28a, 28a′;
- 28b, 28b′), which is arranged on the wiper base body (18a;
- 18b) and is supported between the wiper base body (18a;
- 18b) and at least one of the guide bars (26a, 26a′;
- 26b, 26b′), wherein the wiper base body (18a;
- 18b) includes a side wall (30a, 30a′, 30b, 30b′), and wherein the side wall is positioned laterally between one of the resilient support elements (28a, 28a′;
- 28b, 28b′) and the damping cavity (22a;
- 22b).
A wiper blade apparatus with at least one spring strip (12b, 12b′), having at least one wiper strip unit (14b), which comprises at least one wiper lip (16b) and at least one wiper base body (18b), which bounds at least one recess (20b) to a receptacle of the at least one spring strip (12b, 12b′) and at least one damping cavity (22b) that is separate from the recess (20b), and having at least one wind deflector unit (24b), which at least partially overlaps with the wiper base body (18b) of the wiper strip unit (14b) and which comprises at least two guide bars (26b, 26b′), which extends to both sides of the wiper base body (18b), wherein the wiper strip unit (14b) comprises at least one resilient support element (28b, 28b′), which is arranged on the wiper base body (18b) and is supported between the wiper base body (18b) and at least one of the guide bars (26b, 26b′), wherein the at least one support element (28b′) of the wiper strip unit (14b) is formed from a diagonally extending bar, which is arranged on the wiper base body (18b) with a top end facing away from the wiper lip (16b) and which is arranged on the guide bar (26b, 26b′) of the wind deflector unit (24b) with a bottom end facing away from the wiper lip (16b).
A wiper blade apparatus with at least one spring strip (12b, 12b′), having at least one wiper strip unit (14b), which comprises at least one wiper lip (16b) and at least one wiper base body (18b), which bounds at least one recess (20b) to a receptacle of the at least one spring strip (12b, 12b′) and at least one damping cavity (22b) that is separate from the recess (20b), and having at least one wind deflector unit (24b), which at least partially overlaps with the wiper base body (18b) of the wiper strip unit (14b) and which comprises at least two guide bars (26b, 26b′), which extends to both sides of the wiper base body (18b), wherein the wiper strip unit (14b) comprises at least one resilient support element (28b, 28b′), which is arranged on the wiper base body (18b) and is supported between the wiper base body (18b) and at least one of the guide bars (26b, 26b′), wherein the guide bars (26b, 26b′) of the wind deflector unit (24b) comprise, at a respective free bottom end, a support stage (32b, 32b′), which is provided so as to receive a free end of the at least one support element (28b, 28b′) in a supporting manner.
