    Abstract: 934,249. Flexible resilient seal strips. GENERAL MOTORS CORPORATION. Oct. 27, 1961 [Nov. 25, 1960], No. 38522/61. Class 20 (3). [Also in Group V] A flexible resilient sealing strip 20 has a sealing lip portion 20 of latex foam moulded to a tubular portion 24 of a closed cell material such as neoprene sponge, the strip being attached to a metal car door 34 by nylon studs 28 with their heads in the tube cavity, which are pressed into holes in the door. The tubular portion may also be formed from " mechanical rubber," and may have its long edges smooth or roughened, and may have another layer of neoprene sponge moulded on the opposite side to the lip portion. Either the tubular portion or this third layer may have protruding lips forming a concave surface adjacent the door, and the assembly may have a surface sealing layer such as a film of neoprene cement which may be fortified with graphite or other lubricant.
