INFLATION APPARATUS FOR SAFETY DEVICE

摘要

Safety apparatus disposed within a motor vehicle subject to impact for transmitting an electrical current from a power source to a gas releasing means connected to a gas containing portion of a gas source during a fixed time interval and to a plurality of gas generating charges within a gas generating portion of the gas source during successive time intervals at least two of which are caused to vary in inverse proportion to the impact velocity of the vehicle by means differently responsive to the impact velocity. Pressurized gas is released from the gas containing portion upon receipt of the electrical current by the gas releasing means. Gas generated by each charge receiving an electrical current enters the gas containing portion and admixes with the pressurized gas therein. As a result, the combined pressurized and generated gases pass into a bag, which inflates during a controlled time interval varying inversely with the impact velocity to a controlled pressure varying directly with the impact velocity.
