Abstract
Abstract This invention relates to a vehicle sun roof, preferably transparent or translucent such as glass or plastic, which contains the following characteristics: 1. a frontal bar for aligning the sun roof cover which is an integral part of the cover frame; 2. hingeable means for raising, sealing and locking the cover when in a closed position, and conversely hingeably lowering the cover during opening; 3. means for moving the cover forward and rearward with a minimum of visibility by means of a separate rear crossmember; the crossmember having slidable control cams attached at each end to control the upward movement of the cover rear edge; 4. a sun roof housing with a minimum loss of vehicle headroom; 5. a safety switch for shutting off the motor which is activated when an increased torque is exerted on a rotatable motor housing due to resistance to motion of the cover.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
223 words
A sliding roof arrangement for a vehicle having an opening in the roof thereof comprising: a housing, said housing containing guide rails longitudinally positioned along the outer edges of the opening in the housing, cam stops attached outwardly of said guide rails to said housing, and a cover movable on cover support means slidably attached to said guide rails and capable of effecting a closed and an open position of said cover in said roof opening; cams slidably attached to said cover support means as a cover support means-cam combination, an operating mechanism for moving said cover, said operating mechanism applied from the rear of the housing to the cover through a movable cross member separated from and rearward of the cover and attached to the support means-cam combination, said cover support means-cam combination capable of sliding relative to each other by permitting forward motion to the said cover support means after the cam stop contacts the cam, said cover support means-cam combination hingably attached to the rear of the cover; said cams containing frontal notches capable of engaging projecting tabs attached to the rear and underside of said cover, said cams, upon contacting said cam stops, being capable of disengaging the projecting tabs from said frontal notches, thus allowing said support means to hingably lift said cover to seal the roof opening.
Claim 2
Dependent Claim
223 words
A sliding roof arrangement for a vehicle having an opening in the roof thereof comprising: a housing, said housing containing guide rails longitudinally positioned along the outer edges of the opening in the housing, cam stops attached outwardly of said guide rails to said housing, and a cover movable on cover support means slidably attached to said guide rails and capable of effecting a closed and an open position of said cover in said roof opening; cams slidably attached to said cover support means as a cover support means-cam combination, an operating mechanism for moving said cover, said operating mechanism applied from the rear of the housing to the cover through a movable cross member separated from and rearward of the cover and attached to the support means-cam combination, said cover support means-cam combination capable of sliding relative to each other by permitting forward motion to the said cover support means after the cam stop contacts the cam, said cover support means-cam combination hingably attached to the rear of the cover; said cams containing frontal notches capable of engaging projecting tabs attached to the rear and underside of said cover, said cams, upon contacting said cam stops, being capable of disengaging the projecting tabs from said frontal notches, thus allowing said support means to hingably lift said cover to seal the roof opening.
Claim 3
Dependent Claim
80 words
The sliding roof arrangement of claim 1 where the cover support-cam combination comprises a cover support containing a component having a top horizontal face and a side vertical face, said vertical face having means of attachment to said cam, said cam capable of sliding along said means of attachment, and an elastic means joining the cam to the vertical face of said component, said combination permitting forward motion to said cover support means after the cam stop contacts said cam.
Claim 4
Dependent Claim
88 words
The sliding roof arrangement of claim 1 containing a frontal bar on front cover support means positioned on said guide rails, said frontal bar attached to the front of said cover, and said frontal bar useful in positioning the cover relative to the vehicle roof, housing and guide rails; said frontal bar having adjustable means for attaching to the front cover support means, and said frontal bar having adjustable means for vertically attaching to and adjusting the cover to permit alignment of the cover with the roof opening.
Claim 5
Dependent Claim
88 words
The sliding roof arrangement of claim 2 containing a frontal bar on front cover support means positioned on said guide rails, said frontal bar attached to the front of said cover, and said frontal bar useful in positioning the cover relative to the vehicle roof, housing and guide rails; said frontal bar having adjustable means for attaching to the front cover support means, and said frontal bar having adjustable means for vertically attaching to and adjusting the cover to permit alignment of the cover with the roof opening.
Claim 6
Dependent Claim
60 words
The sliding roof arrangement of claim 1 where the operating mechanism contains the motor-safety switch combination which comprises a rotatable motor, and at least one shut-off switch, said motor mounted so as to be non-rotatable until a predetermined torque is reached, but which rotates when said predetermined torque is exceeded, so as to activate a shut-off switch for said motor.
Claim 7
Dependent Claim
60 words
The sliding roof arrangement of claim 2 where the operating mechanism contains the motor-safety switch combination which comprises a rotatable motor, and at least one shut-off switch, said motor mounted so as to be non-rotatable until a predetermined torque is reached, but which rotates when said predetermined torque is exceeded, so as to activate a shut-off switch for said motor.
Claim 8
Dependent Claim
60 words
The sliding roof arrangement of claim 3 where the operating mechanism contains the motor-safety switch combination which comprises a rotatable motor, and at least one shut-off switch, said motor mounted so as to be non-rotatable until a predetermined torque is reached, but which rotates when said predetermined torque is exceeded, so as to activate a shut-off switch for said motor.
Claim 9
Dependent Claim
60 words
The sliding roof arrangement of claim 4 where the operating mechanism contains the motor-saftey switch combination which comprises a rotatable motor, and at least one shut-off switch, said motor mounted so as to be non-rotatable until a predetermined torque is reached, but which rotates when said predetermined torque is exceeded, so as to activate a shut-off switch for said motor.
Claim 10
Dependent Claim
154 words
A sliding roof arrangement for a vehicle having an opening in the roof thereof comprising a housing, said housing containing guide rails longitudinally positioned along the outer edges of the opening in the housing, a cover movable on front and rear cover support means slidably attached to said guide rails and capable of effecting a closed and an open position of said cover in said roof opening, an operating mechanism for moving said cover, a frontal bar on front cover support means positioned on said guide rails, said frontal bar attached to the front of said cover, and said frontal bar useful in positioning the cover relative to the vehicle roof, housing and guide rails; said frontal bar having adjustable means for attaching to the front cover support means, and said frontal bar having adjustable means for vertically attaching to and adjusting the cover to permit alignment of the cover with the roof opening.
