Energy absorbing fastening system

摘要

A fastening system includes an energy absorbing or impact indicator and at least one or more of the following: (1) a fastening base for mounting in an emergency vehicle, (2) a patient support engageable with a base, (3) a patient securement mechanism for securing a patient on a patient support, (4) a patient securement mechanism for securing a patient to a vehicle, (5) a patient support securement mechanism operable to secure a patient support in an emergency vehicle, or (6) a patient support securement mechanism operable to secure a patient support to a base, wherein the energy absorbing or impact indicator is located (1) at the patient securement mechanism, or (2) at the patient support securement mechanism, or wherein the energy absorbing or impact indicator is between (1) the base and the vehicle, (2) the patient support and the base, (3) the patient securement mechanism and the patient support, (4) the patient support and the emergency vehicle, (5) the patient and the emergency vehicle, or (6) the patient securement mechanism and the emergency vehicle, wherein the energy absorbing device or impact indicator has at least an energy absorbing state and a rigid state or indicates a level of impact at or between any of the respective component or components.

主权项

1. A fastening system comprising:
an energy absorbing device; a fastening base for mounting in an emergency vehicle; a patient support engageable with said base, said energy absorbing device being located between and coupling said patient support and said base; and said energy absorbing device configured and arranged to have an energy absorbing state where said energy absorbing device absorbs energy from at least one of said patient support and said base when subject to an impact force less than a predetermined impact force, and said energy absorbing device configured and arranged to have a rigid state where said energy absorbing device transfers energy between said patient support and said base when subject to an impact force that exceeds the predetermined impact force, and said energy absorbing device configured and arranged to remain operable to couple said patient support and said base in said energy absorbing state and said rigid state.
