Abstract
Abstract A wiper blade having an improved retention clip including a lower portion engaged within a channeled backing strip for limiting lengthwise movement of a squeegee within the channeled backing strip, and an upper deformable abutment portion which extends above the backing strip serving the purpose of limiting movement of a pressure-distributing superstructure with respect to the backing strip to which it is slidably attached. Deformation of the abutment portion of the clip permits detachment of the backing strip and squeegee from the superstructure.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
153 words
In a wiper assembly having a blade subassembly slidably connected to a pressure-distributing superstructure, said blade subassembly including a squeegee member having a wiping portion joined to a retention portion through a reduced neck and a backing strip having juxtaposed projections upstanding from a connecting bridge defining a longitudinal channel for receiving the retention portion of the squeegee lengthwise therein, and wherein said channel extends marginally beyond the respective ends of the squeegee to define end receiving portions, the improvement comprising: a deformable clip having a squeegee stop portion securely engaged within at least one of the end receiving portions of the channeled backing strip, and an abutment portion, connected to the squeegee stop portion, which extends upwardly from the channel and above the connecting bridge of the backing strip, said abutment portion being deflectable whereby the blade subassembly may be detached from the superstructure without separating the clip from the blade subassembly.
Claim 2
Dependent Claim
153 words
In a wiper assembly having a blade subassembly slidably connected to a pressure-distributing superstructure, said blade subassembly including a squeegee member having a wiping portion joined to a retention portion through a reduced neck and a backing strip having juxtaposed projections upstanding from a connecting bridge defining a longitudinal channel for receiving the retention portion of the squeegee lengthwise therein, and wherein said channel extends marginally beyond the respective ends of the squeegee to define end receiving portions, the improvement comprising: a deformable clip having a squeegee stop portion securely engaged within at least one of the end receiving portions of the channeled backing strip, and an abutment portion, connected to the squeegee stop portion, which extends upwardly from the channel and above the connecting bridge of the backing strip, said abutment portion being deflectable whereby the blade subassembly may be detached from the superstructure without separating the clip from the blade subassembly.
Claim 3
Dependent Claim
15 words
The wiper assembly of claim 1 wherein the backing strip is made of extruded plastic.
Claim 4
Dependent Claim
50 words
The wiper assembly of claim 1 wherein the deformable clip is made of a generally S-shaped metal clip in which the squeegee stop portion, which is contained within the lower half of the ''''S,'''' and abutment portion, which is contained within the upper half of the ''''S,'''' are integrally formed.
Claim 5
Dependent Claim
36 words
The wiper assembly of claim 1 wherein the deformable clip is generally U-shaped, the width of the squeegee stop portion being substantially the same as the width of the channel whereby a friction fit is formed.
Claim 6
Dependent Claim
48 words
The wiper assembly of claim 1 wherein the clip has a generally flat portion which fits within the channel and has at least one set of barbs along the outer surface thereof for engagement with the juxtaposed projections of the backing strip along the sides of the channel.
Claim 7
Dependent Claim
27 words
The wiper assembly of claim 1 wherein means are provided for securely engaging the squeegee stop portion within the end receiving portion of the channeled backing strip.
Claim 8
Dependent Claim
78 words
The wiper assembly of claim 6 wherein said means is provided by barbs protruding from the squeegee stop portion of the clip, and wherein the channeled member is made of a plastic material, and wherein at least a portion of the deformable clip contained within the end receiving portion of the channel is embedded within the plastic channel member by virtue of a heating or welding treatment which flows the plastic about the barbs of the deformable clip.
Claim 9
Dependent Claim
44 words
The wiper assembly of claim 1 wherein the abutment portion of the deformable clip is movable toward the superstructure and along the top portion of the connecting bridge of the backing strip, whereby said backing strip and squeegee may be detached from the superstructure.
Claim 10
Dependent Claim
24 words
The wiper assembly of claim 1 wherein the abutment portion of the deformable clip is movable away from the backing strip to permit detachment.
Claim 11
Dependent Claim
36 words
The wiper assembly of claim 1 wherein the abutment portion of the clip is made of a spring-like material which protrudes angularly in orientation with respect to the backing strip, which angular orientation is selectively variable.
Claim 12
Dependent Claim
143 words
In a blade refill the combination comprising: a backing strip having a connecting bridge and juxtaposed projections upstanding from the bridge and defining a longitudinal channel; a Squeegee member having a wiping portion joined to a retention portion through a reduced neck, said retention portion being engaged within the longitudinal channel of the backing strip; said channel extending marginally beyond the respective ends of the squeegee to define end receiving portions; a deformable clip having a squeegee stop portion securely engaged within at least one of the end receiving portions of the channeled backing strip, and an abutment portion, connected to the squeegee stop portion, which extends upwardly from the channel and above the connecting bridge of the backing strip, said abutment portion being deflectable whereby the blade subassembly may be detached from the superstructure without separating the clip from the blade refill.
Claim 13
Dependent Claim
143 words
In a blade refill the combination comprising: a backing strip having a connecting bridge and juxtaposed projections upstanding from the bridge and defining a longitudinal channel; a Squeegee member having a wiping portion joined to a retention portion through a reduced neck, said retention portion being engaged within the longitudinal channel of the backing strip; said channel extending marginally beyond the respective ends of the squeegee to define end receiving portions; a deformable clip having a squeegee stop portion securely engaged within at least one of the end receiving portions of the channeled backing strip, and an abutment portion, connected to the squeegee stop portion, which extends upwardly from the channel and above the connecting bridge of the backing strip, said abutment portion being deflectable whereby the blade subassembly may be detached from the superstructure without separating the clip from the blade refill.
