Provided is a vehicle wiper device including (i) a first motor that includes a first output shaft, that rotates the first output shaft to rotate a wiper arm back and forth about a pivot point of the wiper arm, and that causes a wiper blade coupled to a leading end portion of the wiper arm to perform a back and forth wiping operation between an upper return position and a lower return position on a windshield, (ii) a second motor that changes a wiping range on the windshield by the wiper blade, (iii) a rotation angle detector that detects a rotation angle of the first output shaft, and (iv) a controller that controls the second motor according to a rotation angle of the first output shaft detected by the rotation angle detector in a state in which a broad field of view should be secured on a front passenger seat side.

The invention relates to a wiper motor (10) with a shaft (30) for driving a wiper arm (1), wherein the shaft (30) projects through an opening (31) of a housing (15) and in the region of the opening (31) is mounted radially in a bore (55) of at least one substantially sleeve-shaped element (40), and wherein the sleeve-shaped element (40) is fixed at least axially in the region of the housing (15). According to the invention, it is provided that the sleeve-shaped element (40) has at least two different cross-sections (41, 42), a first cross-section (41) which is designed to protrude axially through the opening (31) and a second cross-section (42) which is designed to be accommodated in an axially fixed manner within said opening (31).

The present invention consists in a bearing (1) of a linkage of a wiper mechanism, characterized in that the bearing (1) includes an arm (11) for retaining a link in a transport position, the retaining arm (11) housing at its free end (11a) an element (13) for locking the link in a transport position; said locking element (13) being mobile in translation between an unlocked position and a locking position in which the link is locked in the transport position.

A vehicular wiper device includes a first wiper arm, a first drive source, a rocking mechanism, a second drive source, an extension and retraction mechanism, and a control unit. A first wiper blade for wiping a surface to be wiped of a vehicle is connected to the front end of the first wiper arm. The first drive source is directly or indirectly affixed to the vehicle body. The rocking mechanism is driven by the drive force of the first drive source and reciprocates and rocks the first wiper arm. The second drive source is directly or indirectly affixed to the vehicle body separately from the first drive source. The extension and retraction mechanism is driven by the drive force of the second drive source and extends and retracts the first wiper arm in the longitudinal direction thereof. The control unit controls the drive of the first drive source and the second drive source so that the extension and retraction operation of the first wiper arm performed by the extension and retraction mechanism will correspond to the rocking operation of the first wiper arm performed by the rocking mechanism.

The swing member (63) to be subjected to swinging drive is integrally provided to the output shaft (56) outside the speed reducer case (52), the speed reducer case (52) is provided with a pair of swing regulating portions (61, 62) which prevents the swing member (63) from being moved beyond the wiping-allowable limit angle (b) by contacting the swing member (63). As a result, the swing member (63) and the swing regulating portions (61, 62) can collectively form the regulating member (60). As a result, essential components (such as fixing plate) can be omitted from the conventional wiper apparatus. Therefore, the wiper apparatus can be improved in assembly workability, size and weight by reducing the number of components thereof, and provided with a regulating member (60) which prevents the wiper member being moved beyond the wiping-allowable limit angle (b).

The present invention relates to a core pin assembly comprising two sliding elements configured for use as a component of a mold assembly for a pivot shaft housing wherein the core pin assembly comprises two sliding elements provided with a plurality of longitudinal projections forming a plurality of longitudinal recesses there between; and a shape of the longitudinal projections of one sliding element corresponds to a shape of the longitudinal recesses of the other sliding element; wherein the two separate sliding elements are configured for engaging in a reversible manner, so that the longitudinal projections of one sliding element are positioned in the longitudinal recesses of the other sliding element. The present invention further relates to a method of manufacturing pivot shaft housing using the core pin assembly. The invention relates also to a pivot shaft housing comprising a hole for supporting a pivot shaft, obtained using this method.

The invention relates to a wiper motor (10), with a shaft (28) for driving a wiper arm (1), wherein the shaft (28) projects through an opening (29) of a housing (15) and wherein in the region of the opening (29) the shaft (28) is mounted radially in a bore in an at least substantially sleeve-shaped element (30; 30a), wherein the sleeve-shaped element (30; 30a) is fixed at least axially in the region of the housing (15), and wherein the sleeve-shaped element (30; 30a) has at least two different cross-sections (33; 33a, 34), a first cross-section (33; 33a) which is designed to protrude axially at least through the opening (29) and a second cross-section (34) which is designed to be axially fixed within said opening (29) or within a receiving space (25) of said housing (15).

A support panel adjacent to the windshield opening has an upper surface and a lower surface with a first shaft opening. A wiper drive mechanism is supported to the vehicle body structure and extends along the lower surface of the support panel. The wiper drive mechanism includes a shaft housing and a wiper shaft pivotally supported within the shaft housing. A water diverting panel at least partially covers the wiper drive mechanism and is attached thereto and has a cylindrically shaped portion extending upward therefrom. The cylindrically shaped portion defines a second shaft opening with the shaft housing and wiper shaft extending upward through the second shaft opening and further extending upward through the first shaft opening. A filter member is mounted to the cylindrically shaped portion above the water diverting panel and below the support panel encircling the shaft housing.

A windshield wiper system for an aircraft includes a wiper arm and a wiper shaft with a first end connected to a base of the wiper arm. An electric motor is coupled to the wiper shaft to rotationally drive the wiper shaft. The windshield wiper system also includes a brake system. The brake system includes an electromagnet comprising an energized mode and a de-energized mode. The brake system also includes an anti-rotation assembly with a first element and a second element. The first element is connected directly to the wiper shaft. The second element is rotationally stationary relative the wiper shaft and the first element. The second element is configured to interlock with the first element to prevent rotation of the first element and the wiper shaft when both the electromagnet is in the de-energized mode and the wiper arm is in a park position.
