主权项

1. An inflatable door seal for a public transportation vehicle, the seal comprising:
a connecting member for connecting the seal to a door or coachwork of a vehicle; at least one reinforcing element coated with an elastomer; wherein the seal defines a hollow space therein, the at least one reinforcing member substantially surrounding the hollow space; wherein the reinforcing element has a first elasticity in a longitudinal direction of the seal and a second elasticity in a transverse direction of the seal, the first elasticity being less than the second elasticity such that the reinforcing element allows the seal to inflate from a non-inflated to an inflated state and expand in the transverse direction thereby sealing while being stable and not expanding in the longitudinal direction; and wherein the door seal is extruded.
