Abstract
The invention concerns a wiper blade for a vehicle, comprising at least one wiper strip intended to come to bear on a glazed surface and at least one bending member (1) housed in a support, the wiper strip being held by the support, the bending member (1) being configured to generate curvature in the wiper blade, the bending member (1) being arranged in the form of a longitudinally extending strip, the strip comprising, seen in cross-section, an intermediate portion (2) arranged between two lateral portions (3a, 3b) of the strip, characterized in that a first thickness (12) of the intermediate portion (2) is less than a second thickness (13) of at least one of the lateral portions (3a, 3b).
Claims12
A vehicle wiper blade comprising:
- at least one wiper rubber configured to come to bear on a glazed surface;
- and
- at least one bending member housed in a support,
- wherein the at least one wiper rubber is retained by the support, the bending member being configured to generate a curvature of the wiper blade, the bending member being in a form of a longitudinally extending strip, the strip including, seen in cross section, an intermediate portion disposed between two lateral portions of the strip, a first thickness of the intermediate portion is less than a second thickness of at least one of the lateral portions,
- wherein the intermediate portion of the bending member is delimited by a first face that has a profile, seen from an exterior of the bending member, that is flat or concave,
- wherein the bending member includes at least one transition regularly disposed between the intermediate portion and at least one of the lateral portions, the at least one transition being a step formed by two right angle bends when the first face is flat, or a progressive extension of the concave profile of the first face when the first face is concave,
- wherein at least one lateral portion of the bending member includes a longitudinal edge surface of the strip, two tops and two chamfers that connect each top to the longitudinal edge surface, and
- wherein at least one of the two tops are edges connecting at least one transition and at least one of the two chamfers.
A vehicle wiper blade comprising:
- at least one wiper rubber configured to come to bear on a glazed surface;
- and
- at least one bending member housed in a support,
- wherein the at least one wiper rubber is retained by the support, the bending member being configured to generate a curvature of the wiper blade, the bending member being in a form of a longitudinally extending strip, the strip including, seen in cross section, an intermediate portion disposed between two lateral portions of the strip, a first thickness of the intermediate portion is less than a second thickness of at least one of the lateral portions,
- wherein a heating film is applied to the bending member,
- wherein the intermediate portion of the bending member is delimited by a first face that has a profile, seen from an exterior of the bending member, that is flat or concave,
- wherein the bending member includes at least one transition regularly disposed between the intermediate portion and at least one of the lateral portions, the at least one transition being a step formed by two right angle bends or a progressive extension of the concave profile of the first face,
- wherein at least one lateral portion of the bending member includes a longitudinal edge surface of the strip, two tops and two chamfers that connect each top to the longitudinal edge surface, and
- wherein at least one of the two tops are edges connecting at least one transition and at least one of the two chamfers.
