Abstract
Abstract In a slidable window of the type used in automobiles, the window is guided in the open position partially by the window frame and partially by a guide rail located in the window shaft of the automobile door. A cable window winder opens and closes the window and has a guide tube portion arranged in parallel with the guide rail. One end of the guide tube portion is fixed to the guide rail and its other end is displaceably secured to the guide rail, preferably by a flexible thermoplastic member, so that errors in parallelism or deviations in curvature between the guide rail and the guide tube portion can be compensated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
111 words
In an apparatus for opening and closing a slidable window, such as a window which can be opened by lowering into the window shaft in a door of an automobile vehicle, comprising a guide rail, a window winder, said window winder including a guide tube having a guide tube portion disposed in parallel relation with said guide rail and fixed at one end to said guide rail, wherein the improvement comprises means for flexibly and displaceably connecting the opposite end of said guide tube portion from its end fixed to said guide rail to said guide rail for permitting limited relative movement between said guide rail and said guide tube portion.
Claim 2
Dependent Claim
111 words
In an apparatus for opening and closing a slidable window, such as a window which can be opened by lowering into the window shaft in a door of an automobile vehicle, comprising a guide rail, a window winder, said window winder including a guide tube having a guide tube portion disposed in parallel relation with said guide rail and fixed at one end to said guide rail, wherein the improvement comprises means for flexibly and displaceably connecting the opposite end of said guide tube portion from its end fixed to said guide rail to said guide rail for permitting limited relative movement between said guide rail and said guide tube portion.
Claim 3
Dependent Claim
60 words
In an apparatus, as set forth in claim 1, wherein said means comprises a flexible connecting piece including two spring arms which grip said guide tube with the adjacent ends of said spring arms disposed in spaced relationship forming a slot, and a projection extending from said spring arms and arranged to be slidably engageable relative to said guide rail.
Claim 4
Dependent Claim
50 words
In an apparatus, as set forth in claim 2, wherein said projection is an elongated member extending from said arms transversely of the axial direction of said guide tube portion, and said elongated member is elastically bendable in the direction transverse to the axial direction of said guide tube portion.
Claim 5
Dependent Claim
54 words
In an apparatus, as set forth in claim 2, wherein said projection extends outwardly from said spring arms perpendicularly to the axis of said guide tube portion and the extension of said projection intersects the axis of said guide tube portion, and said projection being displaceable transversely and longitudinally of said guide tube axis.
Claim 6
Dependent Claim
107 words
In an apparatus, as set forth in claim 1, wherein said means comprises a slotted cylindrically shaped sleeve in resilient engagement with the exterior diameter of said guide tube portion, and an elongated extension secured to and extending tangentially from the opposite side of said sleeve from the slot therein, said projection extending transversely of the axis of said guide tube portion, said projection having at least one elastically resilient arrestor nose therein spaced from the connection of said projection to said sleeve and said arrestor nose arranged to limit the sliding movement of said means at its maximum dimension from the axis of said guide tube.
Claim 7
Dependent Claim
64 words
In an apparatus, as set forth in claim 5, wherein said guide rail has a flat lug pressed from its surface with said lug combining with said guide rail for forming an opening in which said projection on said sleeve is slidably displaceable and said arrestor nose being engageable with said lug for limiting in one direction the limit sliding movement of said means.
Claim 8
Dependent Claim
89 words
In an apparatus, as set forth in claim 1, wherein said means comprises a slotted cylindrically shaped sleeve in resilient engagement with the exterior diameter of said guide tube portion, and a cylindrically shaped projection secured to and extending outwardly from said sleeve on the opposite side thereof from the slot therein and disposes at right angles to the axis of said sleeve, a head secured to the end of said projection spaced outwardly from said sleeve, and said head being elongated in the axial direction of said sleeve.
Claim 9
Dependent Claim
125 words
In an apparatus, as set forth in claim 7, wherein said guide rail includes a section having an elongated hole therein with the elongated dimension of said hole extending transversely of the axial direction of said sleeve, the elongated dimension of said hole being sufficient to pass the elongated dimension of said head and the dimension of said hole normal to its elongated dimension being less than the elongated dimension of said head and at least sufficient to receive the transverse dimension of said projection so that said head and projection can be positioned through the elongated hole and turned 90* for slidably securing said sleeve to said section of said guide rail whereby said projection can slide in the elongated direction of said hole.
Claim 10
Dependent Claim
25 words
In an apparatus, as set forth in claim 2, wherein said connecting piece and projection are formed as a single piece from a thermoplastic material.
Claim 11
Dependent Claim
21 words
In an apparatus, as set forth in claim 9, wherein said connecting piece and projection is injection molded from polyamide 6.
