Abstract

A rigid cover for a vehicle roof opening which includes a cover plate, a peripheral edge clearance sealing strip and a gap compensating element embedded in a plastic frame moulded around the circumference of the cover plate and supporting the sealing strip. The gap compensating element includes a deformation zone that can be permanently deformed in a transverse direction to increase a transverse dimension of the cover to fit the sealing strip against an edge of the roof opening. The outer edge area of the gap compensating element projects out of the plastic frame and has fixing elements for supporting the sealing strip on its outer edge. The gap compensating element can also be entirely embedded in a sealing strip attached to the plastics frame moulded onto the cover plate.

Claims

1. A rigid cover assembly for a vehicle roof opening which can be at least partly displaced out of the roof opening and which fills the roof opening when in a closed position comprising:

a cover plate,

a reinforcement frame supporting a lower peripheral edge of the cover plate,

a unitary plastic frame circumferentially surrounding the cover plate, said plastic frame covering an upper peripheral edge of the cover plate and enclosing said reinforcement frame,

a sealing strip extending around a periphery of said plastic frame, and

a metal gap compensating element between the peripheral edge of said cover plate and said sealing strip, said metal gap compensating element having an inner edge section facing said peripheral edge of the cover plate and embedded in said plastic frame, a deformation zone responsive to applied pressure to permanently deform said metal gap compensating element by increasing a transverse dimension of said element and an outer edge projecting out of said plastic frame, said outer edge being shaped to form fixing elements for supporting said sealing strip on said gap compensating element and responsive to deformation of said deformation zone to move at least a portion of said sealing strip outwardly relative to said peripheral edge of said cover plate.

2. A rigid cover assembly according to claim 1, wherein the deformation zone of said metal gap compensating element is located within the plastics frame.

3. A rigid cover assembly according to claim 1, wherein said outer edge projects substantially horizontally out of said plastic frame and said fixing elements for supporting said sealing strip extend substantially vertically upwards and downwards.

4. A rigid cover assembly according to claim 2, wherein said metal gap compensating element is a folded sheet metal form and said deformation zone includes a cavity bounded by an upper undeformable sheet metal wall partly embedded in the plastic frame and having a horizontal guide section which projects out of the plastic frame and a lower deflected deformable sheet metal wall having a horizontal wall section which also projects out of the plastic frame, said horizontal wall section having an outer edge forming the fixing elements by a first bend approximately vertically downwards, a second bend approximately vertically upwards, and a third bend approximately vertically downwards, a fourth bend providing a horizontal flange directed towards the cavity and located between the guide section and the horizontal wall section said deflected deformable sheet wall is covered on the outside by a thin plastic layer which can be used to transmit pressure applied to the outside of said covering to deform said deformable sheet wall together with said plastic covering.

5. A rigid cover assembly according to claim 4, wherein the lower deflected deformable sheet metal wall is comprised of two wall sections directed obliquely downward and said two wall sections subtend an angle of at least 90°

.

6. A rigid cover assembly according to claim 2, wherein an edge step is formed in the upper surface of the plastic frame, said sealing strip is formed with a projection that can be shifted in a transverse direction to adapt to an increased transverse dimension resulting from deformation of the deformation zone, and said edge step receives and slidably supports said projection.

7. A rigid cover assembly according to claim 1, wherein said plastic frame is rectangular in form and reinforced by the embedded inner edge section of said metal gap compensating element in addition to said reinforcement frame and the reinforcement frame is divided into four separate strip sections with one strip section embedded in each side of the rectangular plastic frame.

8. A rigid cover assembly according to claim 1, wherein said metal gap compensating element is formed by folding a sheet metal blank with said outer edge projecting substantially horizontally out of said plastic frame and comprised of at least two laminae with one lamina on top of the other and at least one of said laminae can move relative to the other lamina during deformation of the deformation zone.

9. A rigid cover assembly according to claim 1, wherein said metal gap compensating element is a folded sheet metal form and said deformation zone includes a cavity bounded in part by a sheet metal wall depending downward in a direction away from said upper peripheral edge of said cover plate and connected to one of said fixing elements and said depending sheet metal wall is responsive to a force applied in a direction toward said upper peripheral edge to permanently deform said metal gap compensating element.
