Abstract
Abstract In a window lifting mechanism for a motorcar window and the like in which a carrier for the window is moved along a guide by bowden cables led from the guide to a drive mechanism in partly arcuate paths, the end sections of the bowden cable casing are connected to the guide by connectors which are unitary pieces of sheet metal including an approximately planar main portion and guide and fastening elements stamped out of the main portion and angularly offset from the same for engagement with the associated casing section.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
In a window lifting mechanism including an elongated guide member, a window carrier member longitudinally movable on the guide member, two connectors connecting respective longitudinal end portions of said guide member to two associated tubular casing sections, two longitudinally terminal portions of at least one elongated tension member being fastened to said window carrier member and extending therefrom into said casing sections respectively, and drive means for longitudinally moving said at least one tension member relative to said guide member and for thereby moving said carrier member, the improvement in at least one of said connectors which consists in said connector being a unitary piece of sheet metal, respective parts of said piece constituting a substantially planar main portion of said one connector and guide and fastening elements angularly offset from said main portion for engagement with the casing section associated with said one connector for fastening said casing section to said guide member in a position in which said casing section defines therein an arcuate path of movement for the corresponding terminal portion of said at least one tension member, said planar main portion being located along the portion of said casing section defining said arcuate path of movement.
Claim 2
Dependent Claim
200 words
In a window lifting mechanism including an elongated guide member, a window carrier member longitudinally movable on the guide member, two connectors connecting respective longitudinal end portions of said guide member to two associated tubular casing sections, two longitudinally terminal portions of at least one elongated tension member being fastened to said window carrier member and extending therefrom into said casing sections respectively, and drive means for longitudinally moving said at least one tension member relative to said guide member and for thereby moving said carrier member, the improvement in at least one of said connectors which consists in said connector being a unitary piece of sheet metal, respective parts of said piece constituting a substantially planar main portion of said one connector and guide and fastening elements angularly offset from said main portion for engagement with the casing section associated with said one connector for fastening said casing section to said guide member in a position in which said casing section defines therein an arcuate path of movement for the corresponding terminal portion of said at least one tension member, said planar main portion being located along the portion of said casing section defining said arcuate path of movement.
Claim 3
Dependent Claim
39 words
In a mechanism as set forth in claim 1, said fastening elements including an abutment aligned with said casing section in the direction of elongation of said guide member for limiting movement of said casing section in said direction.
Claim 4
Dependent Claim
48 words
In a mechanism as set forth in claim 1, a further part of said piece extending into the path of movement of said carrier member on said guide member transversely to said main portion and constituting a stop limiting movement of said carrier member on said guide member.
Claim 5
Dependent Claim
54 words
In a mechanism as set forth in claim 1, said main portion being formed with a plurality of openings therein respectively contiguous to associated ones of said guide and fastening elements, the shapes and dimensions of said openings being substantially similar to the respective shapes and dimensions of the associated guide and fastening elements.
Claim 6
Dependent Claim
32 words
In a mechanism as set forth in claim 1, one of said guide elements being elongated in an arc substantially parallel to said arcuate path of movement and engaging said casing section.
Claim 7
Dependent Claim
61 words
In a mechanism as set forth in claim 1, said guide member including a channel portion having a web and two flanges spacedly projecting from said web in a common direction, a guide shoe being formed with a slot receiving one of said flanges for sliding movement longitudinally of said guide member, said shoe being fixedly fastened to said window carrier.
Claim 8
Dependent Claim
47 words
In a mechanism as set forth in claim 1, another guide shoe fixedly fastened to said window carrier and formed with a slot transverse to the slot receiving said one flange, the other flange of said channel portion carrying an integral rail received in said transverse slot.
Claim 9
Dependent Claim
37 words
In a mechanism as set forth in claim 1, fastening means for fastening said one connector to supporting structure, said fastening means including a fastening lug constituted by a part of said unitary piece of sheet metal.
Claim 10
Dependent Claim
37 words
In a mechanism as set forth in claim 1, said guide member being a unitary body of sheet metal, a part of said unitary body constituting a fastening lug for fastening said guide member to supporting structure.
