Abstract

A windshield wiper frame connector for use in a windshield wiper assembly for motor vehicles which accommodates different size wiper arms, wherein the connector includes a pair of slots, two pair of raised portions and a pair of stoppers on a pair of sidewalls for forming two pairs of spaces, upper and lower elongated seats, and an angled slot and a hole, whereby a hook type wiper arm, or a pin type wiper arm, or a bayonet type wiper arm can be easily connected to a blade unit.

Claims

1. A windshield wiper frame connector for connecting a wiper blade unit to a wiper arm said connector comprising:

an elongated body member having a pair of spaced opposing sidewalls, each said sidewall defining an inner and outer surface, said inner surfaces facing one another, a cross-member formed between and connecting said pair of sidewalls, said cross member extending substantially perpendicular to said sidewalls, each of said sidewalls having a front wing portion as an extension of said sidewalls, said front wing portions also defining the inner surfaces;

a first slot disposed in a lower portion of said body member for rotatably receiving a transverse pin of a wiper blade unit;

a second slot disposed in said lower portion of said body member adjacent to said first slot for rotatably receiving a pin of a pin type wiper arm;

an arc-shaped surface located within said second slot, said arc-shaped surface being provided to cooperate with a reduced diameter portion of said pin of a pin type wiper arm;

a pair of opposing first raised portions disposed on said opposing inner surfaces of said front wing portions of said sidewalls;

a pair of opposing second raised portions disposed on said opposing inner surfaces of said front wing portions of the sidewalls, said pair of first raised portions being adjacent to said pair of second raised portions, said first and second raised portions defining therebetween a first space of predetermined width for receiving and locking outer surfaces of a hook portion of a hook type wiper arm of a first width;

a pair of stoppers disposed on said pair of second raised portions;

said stoppers projecting inwardly toward each other;

said stoppers and said cross-member defining therebetween a second space of a width less than said predetermined width of said first space for alternatively receiving and locking outer surfaces of a hook portion of a hook type wiper arm of a second width different than said first width; and

an upper seat and a lower seat disposed on each said inner surface of said sidewalls, said upper and lower seats being provided for engaging and supporting said hook portion of the hook type wiper arms.

2. The windshield wiper frame connector of claim 1, wherein said upper seats are horizontally elongated without interruption and said lower seats are interrupted by said first and second slots.

3. The windshield wiper frame connector of claim 1, further comprising an angled slot and a hole which are in mutual communication, said angled slot and said hole being disposed in a rear portion of said body member for slidably receiving a bayonet type wiper arm provided with a locking pin for engagement with said hole.
