Abstract: A shoulder- and/or neck-holder, seat-belt, seat and sets of vibration-dampening energy-absorbers are integrated into an energy-absorbing, vibration-dampening safety-seat in order to restrain the shoulders and/or neck of a belted passenger, dampen vibrations and gradually absorb subenergies, resulting from a subdivision of the total energy, just below the respective injury-irrelevant threshold-values in any real-world accident of a transport-system, submarining or during in-flight turbulence. The conversion of an adult-seat into a child-seat or a baby-cot or vice-versa is simple. A rotatable device makes the holder easy to use. Neck- and/or shoulder-shaped, height-, width-adjustable holders and/or neck- and/or shoulder-shaped energy absorbers, attached thereto, ensure complete restraint of the shoulders and necks of passengers with different weights and body-proportions.

Abstract: As yet heads of belted passengers, when thrown forwards in real-world front collisions, crush into vehicle members or inflating airbags. A safety device is equipped with wires, energy-absorbing, vibration-dampening delimiters, a collapsible upper portion of steering column and a pair of independently operating piston devices. The deflection of at least one piston rod in any front or rear collision is exploited to pre-tension the seat belts up to a predetermined length of seat-belt retraction and retract that collapsible upper portion with the steering wheel out of the head-injury area. In order to prevent buckling of longitudinal runners, achieve the highest efficiency of energy-absorption and lower impact energy, to which passengers are exposed, a cone-shaped hub reams, folds and buckles the respective longitudinal runner, loosely guided by the piston rod, guided by a bearing box. The delimiters block further movement of seat-belt wire thus preventing strangulation.

Abstract: 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.
