Abstract
A combination seal is provided for dynamically sealing the interface between an automotive vehicle body and an associated closure panel. The seal provides a compressible sealing portion of bulbous shape and a valve portion that normally seals the interior of the vehicle against the inward passage of fluid and permits venting the interior to the atmosphere upon a certain build-up of pressure within the vehicle body.
Claims15
An air extracting dynamic seal for selectively effecting sealing engagement between a closure panel of an automotive vehicle movable between an open and a closed position with respect to the body of the vehicle and a fixed portion of the body of the vehicle enclosing the interior of the body, the seal comprising:
- a resilient body;
- a mounting portion carried with the body and secured to the fixed portion of the body of the vehicle;
- a compressible sealing portion carried with the body sealingly engageable with the closure panel when the closure panel is in the closed position to prevent fluid passage between the interior of the vehicle body and the atmosphere;
- and
- an extractor valve portion carried with the body having first position blocking fluid passage inwardly to the body of the vehicle and operative in response to an increase in fluid pressure within the body above a predetermined value to permit passage of fluid outwardly of the body of the vehicle.
An air extracting dynamic seal for selectively effecting sealing engagement between a closure panel of an automotive vehicle movable between an open and a closed position with respect to the body of the vehicle and a fixed portion of the body of the vehicle enclosing the interior of the body, the seal comprising:
- a unitary seal body molded of resilient material and having:
- a mounting portion defining a finned channel receivable in push-fit relationship on the fixed portion of the vehicle body;
- a hollow bulbous compressible sealing portion sealingly engageable with the closure panel when the closure panel is in the closed position to prevent fluid passage between the interior of the vehicle body and the atmosphere;
- and
- an extractor valve portion carried with the body having first position blocking fluid passage inwardly to the body of the vehicle and operative in response to an increase in fluid pressure within the body above a predetermined value to permit passage of fluid outwardly of the body of the vehicle.
