Seat belts of a transport system are provided with anti-submarining seat-belt assemblies. A lap-belt portion of each assembly, restraining the lower part of the body of a belted passenger, is subdivided into two anti-submarining belt portions, which properly restrain the thighs when plug-in connecting at least one anti-submarining latch-plate to one of the anti-submarining buckle assemblies, all of which, equipped with energy absorbers, are arranged in a seat cushion. As a result, the energy-absorbing, anti-submarining seat-belt assembly substantially lowers great belt force in an accident, reduces the elongation of the seat belt and prevents submarining.A separately operated release button, when depressed, frees the passenger from the anti-submarining protection.Ease of use is ensured by one-click operation of a master release-button, which, when depressed, releases all latch-plates.Detachable anti-submarining latch plates, when not in use, are stored in a storage box. When needed they are attached to the lap-belt portion.

The present invention prevents a three-dimensional fabric arranged in front surfaces of speakers from flapping due to sound. In the respective front surface sides of, sound-emitting direction regulating members that include annular portions that project forward by a predetermined distance are arranged. A three-dimensional fabric is tensioned and arranged so as to cover the front surface sides of the sound-emitting direction regulating members. When the three-dimensional fabric is pressed against the annular portions configuring the sound-emitting direction regulating members, the annular portions bite into the three-dimensional fabric since the three-dimensional fabric has a predetermined thickness. The annular portions are provided so as to surround diaphragms of the speakers. Sound output from the speakers passes inside the annular portions. However, the periphery of a region of the three-dimensional fabric in which sound passes is supported by the biting of the annular portions, thereby preventing the three-dimensional fabric from flapping widely in response to the sound.
