Abstract
Abstract The window operating mechanism in a motorcar door includes a window support moved by a bowden cable extending in an angular loop. The wire of the cable is protected in the corners of the loop by a flexible sheath deflected into an arc by a rigid U-channel having an open convex side and held in the groove of the channel by annular end pieces. An adjacent straight portion of the wire is fastened to the window support in a slot of a tubular guide having one end received in a blind groove of one of the end pieces.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
231 words
A window operating mechanism comprising: (a) an elongated tubular guide member defining a longitudinal bore therein and formed with a longitudinal slot communicating with said bore; (b) a support assembly slidably guided on said guide member, a portion of said assembly being received in said slot, said assembly including means for supporting the window to be operated; (c) an elongated tension member partly received in said bore and fastened to said portion of said support assembly, a part of said tension member projecting longitudinally from said bore; (d) deflector means for deflecting said projecting part into an arcuate path, (1) said deflector means including an elongated channel portion extending in an arc and formed with a longitudinal groove, and two longitudinally terminal, annular portions connected by said channel portion, (2) said terminal portions each extending in a closed loop about an opening communicating with said groove, (3) one of said terminal portions being formed with a recess extending about the opening thereof and receiving one longitudinal end of said guide member; (e) a tubular sheath having respective portions received in said groove and in the openings of said terminal portions, (1) said tension member extending from said portion of said support assembly through said sheath beyond the other terminal portion of said deflector means; and (f) drive means for longitudinally moving said tension member and for thereby moving said support assembly.
Claim 2
Dependent Claim
231 words
A window operating mechanism comprising: (a) an elongated tubular guide member defining a longitudinal bore therein and formed with a longitudinal slot communicating with said bore; (b) a support assembly slidably guided on said guide member, a portion of said assembly being received in said slot, said assembly including means for supporting the window to be operated; (c) an elongated tension member partly received in said bore and fastened to said portion of said support assembly, a part of said tension member projecting longitudinally from said bore; (d) deflector means for deflecting said projecting part into an arcuate path, (1) said deflector means including an elongated channel portion extending in an arc and formed with a longitudinal groove, and two longitudinally terminal, annular portions connected by said channel portion, (2) said terminal portions each extending in a closed loop about an opening communicating with said groove, (3) one of said terminal portions being formed with a recess extending about the opening thereof and receiving one longitudinal end of said guide member; (e) a tubular sheath having respective portions received in said groove and in the openings of said terminal portions, (1) said tension member extending from said portion of said support assembly through said sheath beyond the other terminal portion of said deflector means; and (f) drive means for longitudinally moving said tension member and for thereby moving said support assembly.
Claim 3
Dependent Claim
45 words
A mechanism as set forth in claim 1, wherein said channel portion has a concave longitudinal face and a convex longitudinal face, and is formed with an elongated opening in said convex face extending substantially from said one terminal portion to said other terminal portion.
Claim 4
Dependent Claim
32 words
A mechanism as set forth in claim 2, wherein said one terminal portion is formed with an annular shoulder in the opening thereof, said sheath engaging said shoulder in longitudinally abutting engagement.
Claim 5
Dependent Claim
19 words
A mechanism as set forth in claim 2, further comprising a reinforcing rib fixedly fastened to said concave face.
Claim 6
Dependent Claim
23 words
A mechanism as set forth in claim 4, further comprising fastening means on said rib for fastening said deflector to a window frame.
Claim 7
Dependent Claim
45 words
A mechanism as set forth in claim 4, wherein said rib, said channel portion, and said terminal portions jointly constitute a unitary piece of material, said bore in said guide member is straight, and said sheath is more flexible than said unitary piece of material.
Claim 8
Dependent Claim
22 words
A mechanism as set forth in claim 1, wherein said one terminal portion includes a wall sealing said recess toward said groove.
Claim 9
Dependent Claim
44 words
A mechanism as set forth in claim 7, wherein said one terminal portion further includes a locking part in said recess, said locking part being received in said slot of the guide member and preventing rotation of the guide member about a longitudinal axis.
Claim 10
Dependent Claim
37 words
A mechanism as set forth in claim 1, wherein said one terminal portion is formed with an annular shoulder in the opening thereof, said mechanism further comprising a compression spring interposed between said shoulder and said sheath.
Claim 11
Dependent Claim
30 words
A mechanism as set forth in claim 9, further comprising receptacle on said spring movable in said opening of the one terminal portion, said sheath being received in said receptacle.
