Locking device between a wiping blade and a windscreen wiper blade holder

#The invention relates to a locking device between a wiping blade and a windscreen wiper blade holder.

#Windscreen wiper arms, in particular of motor vehicles, generally consist of a mobile drive arm that is capable of moving a wiper comprising a support frame or a windscreen wiper blade holder and a wiping blade that is capable of being pinned against a window or a windscreen.

#However, the wiping blade tends to wear with the use of the windscreen wiper, and should be replaced often.

#The present invention is described below with the help of merely descriptive examples that do not limit the scope of the present invention, and with the help of the appended illustrations, in which:

#FIG. 1 is a perspective view of a known type of support frame that is capable of being associated with a windscreen wiper blade and with connection means that are capable of being connected to a drive arm;

#FIG. 2 is a perspective view of a windscreen wiper blade and of the locking device according to the invention prior to being solidly attached to the blade;

#FIG. 1 shows a windscreen wiper with reference number 1, advantageously of a known type, called flat blade, comprising a substantially longitudinal blade holder or a support frame 2.

#The support frame 2 consists of an inner spine 3 made up of a longitudinal horizontal blade inserted in a tubular central body 4 with a substantially longitudinal main axis delimited by a horizontal top wall 5, a horizontal bottom wall 6 and two vertical longitudinal lateral walls 7.

#In the rest of the description, “longitudinal direction” or “horizontal direction” will be used to refer to the direction that is parallel to the longitudinal axis of the windscreen wiper blade, and “transversal direction” or “vertical direction” will be used to refer to the direction that is perpendicular to the longitudinal axis of the inner spine, located on the same plane as the inner spine 3.
