Abstract
A shock absorbing apparatus for an aircraft seat that attenuates shock to passengers and crews includes; an airbag 11 being expanded in a plate shape in a state of less than maximum expansion; an upper flat plate 12 arranged on one side of the airbag 11; a lower flat plate 13 arranged on another side of the airbag 11; a gas supply device 15 for supplying a gas to the airbag 11; and a detector sending a signal to activate the gas supply device 15 by a preset condition. The shock is absorbed by expanding the airbag 11 before the shock is applied to the passenger.
Claims6
A shock absorbing apparatus for an aircraft seat, comprising:
- an airbag being expanded in a plate shape in a state of less than the maximum expansion;
- an upper flat plate arranged on one side of the airbag;
- a lower flat plate arranged on another side of the airbag;
- a gas supply device that supplies a gas to the airbag;
- and
- a detector sending a signal to activate the gas supply device under a preset condition,
- wherein
- the upper flat plate has a lowering restriction member arranged vertically on the airbag side,
- the lower flat plate is arranged at an interval from the lowering restriction member, and
- the lowering restriction member of the upper flat plate abuts against the lower flat plate when the airbag deflates after activation, and thereby lowering of the upper flat plate is restricted.
