Abstract
A wiper system for a vehicle is provided. The wiper system includes a driving assembly. The wiper system further includes a supplementary wiper having a first end that is coupled to a first pivot point of the driving assembly. When the wiper system is activated, the driving assembly is configured to swing the supplementary wiper about the first pivot point from a resting position to an extended position. The supplementary wiper is configured to be statically disposed at the extended position to prevent water from passing over one of two A-pillars of the vehicle to a side window of the vehicle. When the wiper system is deactivated, the driving assembly is configured to stow the supplementary wiper back from the extended position to the resting position.
Claims15
A wiper system for a vehicle, comprising:
- a driving assembly, further comprising:
- a driving implement,
- a wiper linkage, and
- a gear mechanism;
- a supplementary wiper having a first end coupled to a first pivot point of the driving assembly, and
- a primary wiper arrangement having a first end coupled to a second pivot point of the driving assembly that coincides at a common position as the first pivot point;
- wherein
- when activated to an active state, the driving assembly is configured to swing the supplementary wiper about the first pivot point from a resting position proximal to a windshield cowl of the vehicle to an extended position that is proximal to a first end of a windshield and adjacent to one of two A-pillars of the vehicle, and the driving assembly is configured to reciprocally swing the primary wiper arrangement about the second pivot point,
- the supplementary wiper is configured to be statically disposed at the extended position while the wiper system is in the active state to prevent water from passing over one of the two A-pillars of the vehicle to a side window of the vehicle, and
- when deactivated to an inactive state, the driving assembly is configured to stow the supplementary wiper back from the extended position to the resting position.
A wiper system for a vehicle, comprising:
- a driving assembly that includes an electric motor, a wiper linkage, and a gear mechanism;
- a control system communicatively coupled to the driving assembly;
- a supplementary wiper having a first end coupled to a wiper pivot point of the driving assembly;
- and
- a primary wiper having a first end coupled to the wiper pivot point of the driving assembly;
- wherein
- the control system is configured to differentially control movement of the supplementary wiper and the primary wiper about the wiper pivot point;
- when the wiper system is activated to an active state:
- the driving assembly is configured to swing the supplementary wiper about the wiper pivot point from a first resting position proximal to a windshield cowl of the vehicle to a first extended position adjacent to a first end of a windshield that is proximal to a driver's seat of the vehicle,
- the supplementary wiper is configured to be statically disposed at the extended position while the wiper system is in the active state, and
- the driving assembly is configured to reciprocally swing the primary wiper about the wiper pivot point to reciprocally sweep a defined windshield area extending from a second resting position adjacent the first resting position of the supplementary wiper to a second extended position adjacent the supplementary wiper at the first extended position;
- and
- when the wiper system is deactivated to an inactive state, the driving assembly is configured to stow the primary wiper to the second resting position, and also stow the supplementary wiper from the first extended position to the first resting position.
