Abstract
A watertight and airtight seal is useful for use between two structures having relative movement therebetween. The seal apparatus includes a first adhesive bead (38) disposed on a first structural member (12) and a second adhesive bead (44) disposed on a second structural member (22). An elastomeric member (30) includes a first flange (34) portion bonded to the first adhesive bead and a second flange portion (36) bonded to the second adhesive bead (44). The elastomeric member also includes a flexible portion disposed between the first and second flange portions, this flexible portion being operative to freely flex during relative motion between the first and second structural members. This flexibility substantially reduces stress otherwise imparted on the first and second adhesive beads during such movements in the absence of the flexible portion, thereby improving the durability of the seal.
