Abstract
Abstract A window in a motor vehicle is mounted for pivotal movement about a pivot element. An electric motor drives a gear unit whose output shaft is coupled with the pivot in such a manner that pressure manually exerted upon the window disconnects the output shaft from the pivot so that the window can be manually moved in the event this is desirable or necessary because of malfunction of the motor or the gear unit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
In a motor vehicle, in combination, a window; displaceable pivot means mounting said window for displacement between a first open and a second closed position; an electric motor having an output shaft; gear means driven by said motor and operative for displacing said pivot means in a sense effecting displacement of said window between said positions; and manually releasable coupling means connecting said gear means and said pivot means and accessible to an operator of the motor vehicle, for enabling disconnecting of said gear means from said pivot means as a precedent to manual displacement of said window between said positions, said coupling means including a first coupling component provided on said output shaft, and a second coupling component provided on said pivot means and frictionally engaging said first coupling component, said coupling means being constructed and arranged for disengagement of said coupling components in response to exertion of pressure upon said window at least when the latter is in said open position.
Claim 2
Dependent Claim
163 words
In a motor vehicle, in combination, a window; displaceable pivot means mounting said window for displacement between a first open and a second closed position; an electric motor having an output shaft; gear means driven by said motor and operative for displacing said pivot means in a sense effecting displacement of said window between said positions; and manually releasable coupling means connecting said gear means and said pivot means and accessible to an operator of the motor vehicle, for enabling disconnecting of said gear means from said pivot means as a precedent to manual displacement of said window between said positions, said coupling means including a first coupling component provided on said output shaft, and a second coupling component provided on said pivot means and frictionally engaging said first coupling component, said coupling means being constructed and arranged for disengagement of said coupling components in response to exertion of pressure upon said window at least when the latter is in said open position.
Claim 3
Dependent Claim
56 words
In a motor vehicle as defined in claim 1, said gear means having an output shaft coaxial with said pivot means an each having a projecting arm pivotable in response to turning movement of said output shaft and pivot means, respectively; and wherein said coupling means engages and circumferentially connects respective free ends of said arms.
Claim 4
Dependent Claim
46 words
In a motor vehicle as defined in claim 2, said coupling means comprising a projection on said free end of one of said arms, and spring means on said free end of the other arm and embracing said projection from opposite sides with a predetermined force.
Claim 5
Dependent Claim
136 words
In a motor vehicle, in combination, a window; displaceable pivot means mounting said window for displacement between a first and a second position about a pivot axis, said pivot means having a first projecting arm; an electric motor; gear means driven by said motor and operative for displacing said pivot means in a sense effecting displacement of said window between said position, said gear means having an output shaft coaxial with said pivot means and a second projecting arm; manually releasable coupling means connecting said gear means and pivot means and accessible to an operator of the vehicle, said coupling means comprising a projection on a free end of one of said arms, and substantially U-shaped spring means on a free end of the other arm and embracing said projection from opposite sides with predetermined force.
Claim 6
Dependent Claim
136 words
In a motor vehicle, in combination, a window; displaceable pivot means mounting said window for displacement between a first and a second position about a pivot axis, said pivot means having a first projecting arm; an electric motor; gear means driven by said motor and operative for displacing said pivot means in a sense effecting displacement of said window between said position, said gear means having an output shaft coaxial with said pivot means and a second projecting arm; manually releasable coupling means connecting said gear means and pivot means and accessible to an operator of the vehicle, said coupling means comprising a projection on a free end of one of said arms, and substantially U-shaped spring means on a free end of the other arm and embracing said projection from opposite sides with predetermined force.
Claim 7
Dependent Claim
42 words
In a motor vehicle as defined in claim 4, said other arm being of substantially U-shaped cross-section and having a bight portion and a pair of leg portions projecting beyond said bight portion at said free end and constituting said spring means.
Claim 8
Dependent Claim
38 words
In a motor vehicle as defined in claim 4, said spring means comprising a substantially U-shaped clamp having a bight fixed to said free end of said other arm, and a pair of legs springily engaging said projection.
Claim 9
Dependent Claim
61 words
In a motor vehicle as defined in claim 4, said spring means comprising a pair of spring portions defining between themselves an inner space dimensioned for clamping accommodation of said projection, and an outer space converging towards and merging with said inner space and forming a circumferentially facing open side for passage of said projection into and out of said space.
