First Claim
Patent Images
1. An energy absorption assembly comprising:
- structure having at least one inlet and at least one outlet;
an elastic covering at least partially defining an interior region in fluid communication with said at least one inlet and said at least one outlet of the structure;
a gas source in selective fluid communication with the at least one inlet;
an inlet control valve operative to control fluid communication between the gas source and the at least one inlet; and
a pressure relief valve in fluid communication with the at least one outlet.

Abstract
A reversibly deployable energy absorbing assembly includes a rigid support structure having at least one inlet and at least one outlet; a flexible covering sealingly engaged with the rigid support structure to define an inflatable interior region; a gas source in fluid communication with the at least one inlet; an inlet control valve positioned intermediate the gas source and the at least one inlet; and an actively controlled pressure relief valve in fluid communication with the at least one outlet. The inlet control valve and the pressure relief valve are adapted to provide a response suitable for use in vehicle impact management.
