A motor vehicle screen wiper blade comprises an articulated structure which carries, by means of a set of grips, a wiping strip of flexible material which it applies against the glass surface to be swept, so that the wiping strip follows the curvature of the latter. The grips grasp a longitudinal support or claw portion of the wiping strip, and the wiper blade includes at least one accessory such as a flexible aerodynamic deflector. The accessory includes at least one fastening lug for fastening it on the blade, this fastening lug being interposed between a grip of the latter and the claw portion of the wiping strip.

A screen wiper, in particular for a motor vehicle windshield, comprises: an elongate wiper blade having a flexible wiping strip for contact with a curved swept surface, the wiping strip being mounted on the blade in such a way that it can deform in one plane so as to follow the curvature of the swept surface; and an elongate flexible deflector which is so configured as to form a mask that tends to divert air streams so that, when the vehicle is travelling at high speeds, an aerodynamic force is exerted on the blade which tends to urge the flexible wiping strip into contact with the swept surface. The deflector is able to deform on the wiper blade, and its deformation is controlled by the flexible wiping strip itself. The wiper includes, in at least two points along the length of the wiper blade, means for transmitting to the deflector the deformation of the wiping strip, so that this latter deformation is reproduced in the deflector. The blade has first guide means, and the deflector has second guide means. These guide means are arranged to cooperate with each other in sliding movement in at least two points along the length of the wiper blade, so as to guide the deformation of the deflector.

The invention concerns a windscreen wiper for a motor vehicle, of the type having a windscreen wiper arm provided with an articulated structure which carries, by means of a series of claws, a wiper blade made of a flexible material, and of the type having a flexible aerodynamic deflector mounted on the arm, wherein the deflector has at least one clasp for fixing it onto the blade of the arm.

A motor vehicle screen wiper is of the type comprising a screen wiper blade having an articulated structure which carries, by means of a set of gripping elements, a wiping strip of flexible material. It also includes a flexible aerodynamic deflector mounted on the blade. The deflector includes at least one fastening lug which is fitted on to a gripping element of the articulated structure of the blade.

A windshield wiper apparatus comprises an arm carrying a blade. The latter comprises a mounting member carrying a wiping strip, the apparatus being adapted to be fitted with an air deflector. In accordance with the invention, the air deflector is carried by the arm or the blade, through at least two articulations. The invention is especially applicable to automotive vehicles.

A windscreen wiper comprising an air deflector has the form of an arm with a windscreen wiper device articulated thereto, and an air deflector carried by at least one of the elements of the windscreen wiper so as to deflect the air flows which impinge against the elements of the windscreen wiper. An auxiliary air deflector is provided between the air deflector and the surface to be wiped.

An anti-lift deflector for a windscreen wiper includes a hooking member for mounting the deflector onto a wiper or wiper arm and an aerodynamic blade attached to the hooking member and having a substantially flat first zone extending rearwardly from a leading edge of the blade followed by a second zone which is inclined relative to the first zone and which terminates at a trailing edge of the blade. During use of the deflector, the first zone is slightly inclined relative to the surface to be wiped and the second zone is inclined relative to the surface to be wiped at an angle greater than the first zone. This creates a surface effect giving a relatively large pressure decrease below the deflector, thus forcing the wiper blade into contact with the surface to be wiped.

Windscreen wiper and deflector therefor

In a deflector for a windshield wiper including an arm on which a blade is pivoted, the deflector is carried by at least one of the elements comprising the arm and blade of the wiper, in such a way as to divert the air streams. In accordance with the invention, the deflector comprises a main section which is carried by at least one of the said elements of the windshield wiper, together with at least one lateral end portion which is movable with respect to the main section.

The invention is concerned mainly with a wiping strip for a windshield wiper blade, the strip comprising a base and a wiping element for wiping contact with a surface. The wiping element is articulated on the base through a web portion which is protected from deposits of mud, ice etc. by two wing portion which also improve the aerodynamic performance of the wiping strip. The invention is particularly applicable to equipment for automotive vehicles.

Combined air deflector and windshield wiper housing

An air flow deflector for a windshield wiper includes a profiled portion joined to a means for attaching the deflector on a wiper blade or on a wiper arm. The deflector includes surfaces which obstruct the air flow. In addition, it includes guide means for the air flow. The invention is particularly applicable to windshield wiper systems for automotive vehicles.

A windshield wiper drive mechanism includes a crank driven by a motor shaft and having, towards the end of the crank remote from the motor shaft, a crank pin carrying an eccentric crank head piece on which a crosshead is pivoted. The head piece carries a latch which includes a latch finger movable under the action of a resilient member and arranged to leave the crank head piece free to move with respect to the crank when the latter is rotating in a first direction, but to prevent such relative rotation when the crank is rotating in the opposite direction. The latch finger includes a radial latch arm extending outwardly, while the crosshead has a recess for receiving the latch arm. The crank head piece has an opening for receiving the free end of the latch finger. The latch arm is so positioned, and is of such thickness, that, when the latch finger is engaged in the opening in the crank, the latch arm lies between the face to face surfaces of the crosshead and of the crank. The crank head piece is placed so as to face towards the crank.

A windscreen wiper device comprises a drive crank 6 mounted fast on a drive shaft 7 of a drive motor, a connecting rod 5 pivotally mounted on said drive crank by means of a crank pin means, and a windscreen wiper blade support arm 2 connected to said connecting rod 5 so that rotation of said drive crank 6 by said drive motor rotating in a first direction sweeps said support arm 2 through a predetermined arc. Means is provided for displacing said crank pin means between a first position, which is proximal of said drive shaft 7, to a second position, distal of said drive shaft 7, and means for locking said crank pin means in said first or second position, said displacing means releasing said locking means and displacing said crank pin means from said first to said second position whereat it is locked by said locking means when said motor rotates in a direction opposite to said first direction, and releasing said locking means and displacing said crank pin means from said second position to said first position whereat it is locked by said locking means when said motor rotates in said first direction.
