Airbag protection for motor vehicle seat - distributes separate halves on each side of seat to enclose upper part of body

摘要

Each section is located in the upright edges of the seat back, the seat back being shaped for lateral support. The air-bag sections are expanded to form shaped supports which unfold to grip the sides and front of the upper torso and head. The protection provides support for seats facing either way and is suitable for swivel mounted passenger seats. The air-bag sections have gas generating layers spaced inside the structure. The sections are progressively activated by a central control. The expansion rate of the sections is controlled to achieve the enclosing action of the support (9,10). USE/ADVANTAGE - Improved protection in all directions. Passenger vehicles including aircraft.
