ABSTRACT:
A seal assembly primarily for recreational vehicles that have an expandable room. The seal assembly seals the opening in a fixed wall of the vehicle through which the expandable room extends. The seal assembly includes a retainer that is attached to a fixed wall of the vehicles, the retainer holding a bulb-type seal properly in place. The retainer securely holds the bulb seal in place until it is compressed by the expandable room, and the retainer further functions to prevent the bulb seal from being crushed which could cause premature failure of the seal. The seal assembly also provides for relative movement in different directions between the meeting surfaces of the fixed room and moveable room. In this way, it acts as a low friction bearing surface while still maintaining a complete and positive seal at all times.
