Abstract
The invention proposes a motor vehicle windscreen wiper of the type in which a cover (10), intended completely to cover over a drive head, includes two longitudinal lateral flanks (16) joined together by a transverse back (18) which includes an upper longitudinal part (24) and a downwards-curved part (86) at its rear end. The transverse back of the cover (10) includes an aperture (14) giving access to means for fixing the drive head onto the end of an alternating-sweep drive shaft. A cap (12) is provided, the contour (44, 46, 48) of which is complementary to that (30, 32, 34) of the aperture (14), which is mounted articulated (50, 60) on the cover (10) between a service position in which it blocks off the aperture (14) and an open raised position in which the aperture (14) is clear.
Claims15
Motor vehicle windscreen wiper of the type in which a cover (10) is intended completely to cover over an alternating-sweep drive head for a windscreen wiper blade with respect to which it is mounted articulated about a transverse axis (20), between a service position and a raised position, of the type in which the cover (10) includes two longitudinal lateral flanks (16) joined together by a transverse back (18) which includes an upper longitudinal part (24) and a downwards-curved part (86) at its rear end, characterised in that the transverse back of the cover (10) includes an aperture (14) giving access to means for fixing the drive head onto the end of an alternating-sweep drive shaft, and in that a cap (12) is provided, the contour (44, 46, 48) of which is complementary to that (30, 32, 34) of the aperture (14), which is mounted articulated (50, 60) on the cover (10) between a closed service position in which it blocks off the aperture (14) and an open raised position in which the aperture (14) is clear.
Windscreen wiper according to the preceding claim, characterised in that the cap (12) is mounted articulated on the cover (10) about a transverse axis (A1, A2) arranged in the vicinity of the front transverse edge (30) of the aperture (14).
Windscreen wiper according to any one of the preceding claims, characterised in that the means for articulating the cap (12) onto the cover (10) include an articulation tab (50) with a circular-arc profile, with a concave upper face (52), which is guided in circular sliding in a slot (60) with a profile complementary to that of the cover (10).
Windscreen wiper according to the preceding claim, characterised in that the crosspiece (64) of the cover (10) includes an elastically deformable longitudinal tongue (72) the edge of the free front end (62) of which constitutes the said parallel transverse edge which delimits the guide slot (60).
Windscreen wiper according to the preceding claim, characterised in that the edge of the free front end (62) of the tongue interacts with a notch (79) formed on the lower face (54) of the articulation tab (50), in the vicinity of the free front end (81) of the latter, so as to constitute an end stop which determines the raised angular position of the cap and retains the articulation tab (50) in the guide slot (60).
Windscreen wiper according to any one of the preceding claims, characterised in that elastic means (80, 84) are provided for locking the cap (12) in its closed position.
Windscreen wiper according to the preceding claim, characterised in that the elastic locking means include at least one elastic locking strip (80) which extends vertically downwards from the rear transverse edge (46) of the cap (12) and the free end of which includes a locking nose (82) which interacts with a rib (84) arranged face-to-face in the inner face (86) of the curved rear part (26) of the back of the cover.
Windscreen wiper according to any one of the preceding claims, characterised in that the aperture (14) is delimited by a front transverse edge (30) formed in the longitudinal upper part (24) of the back (18) and by a rear transverse edge which is formed in the downwards-curved rear part of the back and which is offset vertically downwards with respect to the front transverse edge (30).
Windscreen wiper according to the preceding claim, characterised in that the aperture (14) is delimited by two longitudinal edges (34) formed in the two longitudinal lateral flanks (16).
Windscreen wiper according to any one of the preceding claims, characterised in that the cover (10) is a rear casing-shaped part of an arm which carries a windscreen wiper blade.
