Abstract
Abstract A sealing arrangement for an automotive body closure such as a sliding roof comprises a sealing member including a tubular sealing portion and a shorter reservoir portion. The two portions are filled with hydraulic fluid and communicate with one another. When the closure member is closed, the sealing portion is not under pressure and offers little resistance to the movement of the closure member. After closing, an actuator such as a crank is retracted and in so doing acts through a rack and pinion on an actuating device which compresses the reservoir portion and thus pressurizes the sealing member to improve the sealing of the joint.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A sealing arrangement for a joint between an opening in the bodywork of a vehicle and a closure member for the opening, the closure member having an operating lever movable into a locking position after the closure member is closed, the sealing arrangement comprising a sealing member having a generally tubular sealing portion positioned adjacent the opening and a tubular fluid reservoir portion contiguous with the sealing portion along part of the length thereof and in fluid communciation therewith, both portions being filled with a pressure medium, and means operative in response to movement of the operating lever into the locking position after closing of the closure member to compress the reservoir portion and thereby increase the pressure within the tubular sealing portion.
Claim 2
Dependent Claim
123 words
A sealing arrangement for a joint between an opening in the bodywork of a vehicle and a closure member for the opening, the closure member having an operating lever movable into a locking position after the closure member is closed, the sealing arrangement comprising a sealing member having a generally tubular sealing portion positioned adjacent the opening and a tubular fluid reservoir portion contiguous with the sealing portion along part of the length thereof and in fluid communciation therewith, both portions being filled with a pressure medium, and means operative in response to movement of the operating lever into the locking position after closing of the closure member to compress the reservoir portion and thereby increase the pressure within the tubular sealing portion.
Claim 3
Dependent Claim
37 words
A sealing arrangement as defined in claim 1 for a crank-operated sliding roof panel of a motor vehicle, wherein the sealing member is received on a flange of the sliding cover panel to engage the roof opening.
Claim 4
Dependent Claim
39 words
A sealing arrangement as defined in claim 2, wherein that the means for compressing the reservoir portion comprises a pressure plate displaceably guided in an end face of the roof opening by way of pins received in corresponding bores.
Claim 5
Dependent Claim
32 words
A sealing arrangement as defined in claim 3, wherein the pressure plate is coupled to the crank of the sliding roof panel by means of a connection including a rack and pinion.
