Abstract
The invention relates to a drive arm for driving a wiper blade intended for a motor vehicle, the drive arm extending in a longitudinal direction (X), the drive arm comprising at least one first attachment means (224) for a first end of an elastic return device and at least one second attachment means (234) for the first end of the elastic return device, characterized in that a first distance (d1) measured parallel to the longitudinal direction (X) between the first attachment means (224) and the second attachment means (234) is not zero.
Claims8
A drive arm for driving a wiper blade for a motor vehicle, the drive arm extending along a longitudinal direction and comprising:
- at least one first attachment slot for a first end of an elastic return device;
- at least one second attachment slot for the first end of the elastic return device;
- and
- at least one third attachment slot for the first end of the elastic return device,
- wherein a first distance measured parallel to the longitudinal direction between the first attachment slot and the second attachment slot is non-zero,
- wherein a second distance measured between the first attachment slot and the third attachment slot being non-zero and a third distance measured between the second attachment slot and the third attachment slot being non-zero,
- wherein the third attachment slot is the longest, and is located between the first and second attachment slots along a direction transverse to the longitudinal direction, and
- wherein the first attachment slot, the second attachment slot, and the third attachment slot are offset relative to one another along the longitudinal direction.
A wiper system for a motor vehicle, comprising:
- at least one wiper blade carrying at least one wiper rubber configured to come into contact with a glazed surface of the motor vehicle;
- and
- at least one drive arm, the drive arm being configured to drive the wiper blade in rotation and extending along a longitudinal direction, the drive arm comprising:
- at least one first attachment slot for a first end of an elastic return device;
- at least one second attachment slot for the first end of the elastic return device;
- and
- at least one third attachment slot for the first end of the elastic return device,
- wherein a first distance measured parallel to the longitudinal direction between the first attachment slot and the second attachment slot is non-zero,
- wherein a second distance measured between the first attachment slot and the third attachment slot being non-zero and a third distance measured between the second attachment slot and the third attachment slot being non-zero,
- wherein the third attachment slot is the longest, and is located between the first and second attachment slots along a direction transverse to the longitudinal direction, and
- wherein the first attachment slot, the second attachment slot, and the third attachment slot are offset relative to one another along the longitudinal direction.
