The present invention concerns a device (1) for retaining a linkage (3) of a wiper mechanism in a transport position, retaining device (1) includes: a clip comprising two elastic arms intended to cooperate with a bush (31) of the linkage (3), and a retaining staple intended to cooperate with a link (33) of the linkage (3), the retaining staple being connected to the clip so that in the mounted state the retaining device (1) connects the link (33) to the bush (31) in a fixed manner in a close position of the bush (31) relative to the link (33).

The present invention concerns a key (1) for locking a link including a U-section and a crank of a linkage of a wiper mechanism in a transport position, characterized in that it comprises: a shaft (11) having at one end a radial holding excrescence (13) and at the other end an enlarged head (15) intended to cooperate with a hollow part of the U-section forming the link, and a first radial finger (17) configured to be housed in a slot for locking the link 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.

A windshield wiper system for an aircraft is provided and includes a motor, an output shaft, a wrap spring and crank rocker mechanism (WSCRM) to which the motor and the output shaft are coupled and a controller. By way of the WSCRM, first directional rotation input to the WSCRM from the motor via a two-stage gear reduction is converted such that the output shaft drives wiper blade oscillation through a first sweep angle and second directional rotation input to the WSCRM from the motor is converted such that the output shaft drives wiper blade oscillation through a second sweep angle. The controller is configured to control the motor such that the first directional rotation is continuously or non-continuously input during first or second flight conditions, respectively, and the second directional rotation is continuously input during third flight conditions.

The invention relates to a drive device for a windscreen wiping device (1), comprising an electric drive motor (3) and a transmission (4) for driving an output shaft (5), said output shaft supporting the first wiper arm (6) and drives a transmission rod assembly (8) which actuates a second wiper arm (13). The invention relates to, in particular, the connection of the drive shaft to the transmission rod assembly.

In the case of a windshield wiper system with two opposite wipers 1, 2, 4, 5 and two reversing motors 6, 7, the risk of a collision of the wipers can be diminished greatly in that a defined phase displacement is generated between the wiping movements of the two wipers, which are driven in a reversing manner, with the aid of the lever mechanism 8 associated with the reversing motors, and said phase displacement is arranged so that the one wiper is leading relative to the other wiper in the first wiping direction and lagging in the second wiping direction.

The invention relates to a wiper motor (10) for the cleaning of vehicle windows, with an output element (17) rotatable about an axis (19), wherein in the output element (17) at a distance (a) the first axis (19) a bearing mount (25) is constructed for a drive lever (30) for driving a wiper shaft (11), wherein the wiper shaft (11) is pivotably mounted in a further axis (16) arranged at least substantially parallel to the axis (19) of the output element (17), and wherein the drive lever (30) is received with an extension (35) in a clamping manner in the bearing mount (25) and extends at least substantially in a plane arranged perpendicularly to the axes (16, 19). According to the invention, it is provided that the extension (35) has a fastening region (36) in the shape of a spherical segment, which cooperates with the bearing mount (25), and that the extension (35) is pivot able about a centre point of the fastening region (36).

The controller is configured to control the motor such that the first directional rotation is continuously or non-continuously input during first or second flight conditions, respectively, and the second directional rotation is continuously input during third flight conditions.

A drive with a motor and devices for coupling the motor to a driving object. The coupling devices include a centrifugal mass which is movable by the motor, and an impact stop, which is connected to the driving object, for the centrifugal mass.

The present invention relates to a pivot assembly for a vehicle wiper system. The assembly includes a pivot shaft rotatably supported in central passage of a pivot housing, a lever coupled to the pivot shaft, and a cover. The cover includes a tubular portion, cylindrical step and a transition portion integrally formed between the tubular portion and the cylindrical step. The cover further includes a cantilever snap extending from inner surface of the transition portion, in longitudinal direction of the cover. A protrusion is formed in the cylindrical step at a location adjacent to the snap. The tubular portion of the cover is received over pivot shaft and a locking profile formed at free end of the snap is received in a recess formed in top end of the pivot housing, thereby restricting longitudinal and rotational movements of the cover with respect to the pivot housing.
