Wiper adapter and wiper assembly incorporating the same
An adapter for attaching to a wiper arm attachment member having a track defined by a base and walls depending therefrom, a bent tab extending outwardly from the base, and fins that extend from the walls. The adapter has a body with a first and second ends. A stop wall formed at the first end abuts the track. A pair of outer walls extend between the first and second ends. A strap connects the outer walls for engaging the base. A pair of inner walls are spaced laterally between the outer walls and are arranged at least partially under the strap. A cantilevered finger extends from each of the inner walls with a tab formed adjacent to the second end. The tabs extend away from each other and are arranged to engage respective fins to prevent movement between the adapter and the attachment member when the stop wall abuts the track.
1. An adapter for use in releasably attaching a wiper assembly to a wiper arm having an attachment member including a track defined by a base and walls depending therefrom, a bent tab extending outwardly from the base, and fins that extend from the walls, said adapter comprising:
a body having a first end and a second end;
a stop wall formed on said body adjacent to said first end for abutting at least a portion of the track of the attachment member of the wiper arm;
a pair of outer walls extending longitudinally between said first end and said second end;
a strap connecting said outer walls for engaging the base of the attachment member of the wiper arm;
a pair of inner walls spaced laterally between said outer walls and arranged at least partially under said strap; and
a cantilevered finger extending longitudinally from each of said inner walls with a locking tab formed adjacent to said second end, said locking tabs extending laterally away from each other and including a tapered outer wall, said locking tabs arranged so as to respectively engage the fins of the attachment member so as to prevent longitudinal movement between said adapter and the attachment member when said stop wall abuts the track of the attachment member.
2. A wiper assembly for use in releasably attaching to a wiper arm attachment member having a track defined by a base and walls depending therefrom, a bent tab extending outwardly from the base, and fins that extend from the walls, said wiper assembly comprising:
a wiping element adapted to contact the surface to be wiped;
at least one elongated spline acting to support said wiping element;
a coupler operatively attached to said spline; and
an adapter pivotally attached to said coupler, said adapter including:
a body having a first end and a second end;
a stop wall formed on said body adjacent to said first end for abutting at least a portion of the track of the attachment member of the wiper arm;
a pair of outer walls extending longitudinally between said first end and said second end;
a strap connecting said outer walls for engaging the base of the attachment member of the wiper arm;
a pair of inner walls spaced laterally between said outer walls and arranged at least partially under said strap; and
a cantilevered finger extending longitudinally from each of said inner walls with a locking tab formed adjacent to said second end, said locking tabs extending laterally away from each other and including a tapered outer wall, said locking tabs arranged so as to respectively engage the fins of the attachment member so as to prevent longitudinal movement between said adapter and the attachment member when said stop wall abuts the track of the attachment member.
3. An adapter for use in releasably attaching a wiper assembly to first and second wiper arm attachment member types, the first attachment member type including a track defined by a base and walls depending therefrom, a bent tab extending outwardly from the base, and fins that extend from the walls; the second attachment member type extending to a terminal end with an upper wall and a pair of side walls depending therefrom, the side walls each having an inwardly-extending protrusion spaced longitudinally from the terminal end and a U-shaped cutout formed at the terminal end defining upper and lower cutout edges, and the upper wall having an aperture spaced longitudinally from the terminal end; said adapter comprising:
a body having a first end and a second end;
a stop wall formed on said body adjacent to said first end for abutting at least a portion of:
the track of the first attachment member type, or
the terminal end of the second attachment member type;
a pair of outer walls extending longitudinally between said first end and said second end;
a strap connecting said outer walls for engaging:
the base of the first attachment member type, or
the upper wall of the second attachment member type;
a pair of inner walls spaced laterally between said outer walls and arranged at least partially under said strap;
a cantilevered finger extending longitudinally from each of said inner walls with a locking tab formed adjacent to said second end, said locking tabs extending laterally away from each other and arranged so as to respectively engage the fins of the first attachment member type so as to prevent longitudinal movement between said adapter and the first attachment member type when said stop wall abuts the track of the first attachment member type;
a resilient finger operatively attached to said body between said inner walls and having a tooth for engaging the aperture of the second attachment member type so as to prevent longitudinal movement between said adapter and the second attachment member type when said stop wall abuts the terminal end of the second attachment member type; and
at least one brace formed on said body at said first end for being received in one of the cutouts of the second attachment member type when said tooth of said resilient finger engages the aperture of the second attachment member type wherein said brace is adapted and arranged to at least partially abut the lower cutout edge of the second attachment member type and remain spaced from the upper cutout edge of the second attachment member type.
4. A wiper assembly for use in releasably attaching to first and second wiper arm attachment member types, the first attachment member type including a track defined by a base and walls depending therefrom, a bent tab extending outwardly from the base, and fins that extend from the walls; the second attachment member type extending to a terminal end with an upper wall and a pair of side walls depending therefrom, the side walls each having an inwardly-extending protrusion spaced longitudinally from the terminal end and a U-shaped cutout formed at the terminal end defining upper and lower cutout edges, and the upper wall having an aperture spaced longitudinally from the terminal end; said wiper assembly comprising:
a wiping element adapted to contact the surface to be wiped;
at least one elongated spline acting to support said wiping element;
a coupler operatively attached to said spline; and
an adapter pivotally attached to said coupler, said adapter including:
a body having a first end and a second end;
a stop wall formed on said body adjacent to said first end for abutting at least a portion of:
the track of the first attachment member type, or
the terminal end of the second attachment member type;
a pair of outer walls extending longitudinally between said first end and said second end;
a strap connecting said outer walls for engaging:
the base of the first attachment member type, or
the upper wall of the second attachment member type;
a pair of inner walls spaced laterally between said outer walls and arranged at least partially under said strap;
a cantilevered finger extending longitudinally from each of said inner walls with a locking tab formed adjacent to said second end, said locking tabs extending laterally away from each other and arranged so as to respectively engage the fins of the first attachment member type so as to prevent longitudinal movement between said adapter and the first attachment member type when said stop wall abuts the track of the first attachment member type;
a resilient finger operatively attached to said body between said inner walls and having a tooth for engaging the aperture of the second attachment member type so as to prevent longitudinal movement between said adapter and the second attachment member type when said stop wall abuts the terminal end of the second attachment member type; and
