Abstract
An ejection system is disclosed herein. The ejection system includes a seat having a seat bucket and a seat back, a passive head and neck protection device coupled to the seat back, and an ejection initiation system. The ejection initiation system includes a pull handle coupled to the seat bucket, a first connector having a first end coupled to the pull handle, an ejection sequence initiation device configured to initiate an ejection sequence, a passive head and neck protection mechanism configured to activate the passive head and neck protection device, and an ejection pull connector having a first end and a second end, the second end coupled to the ejection sequence initiation device and to the passive head and neck protection mechanism.
Claims20
An ejection system, comprising:
- a seat having a seat bucket and a seat back;
- a passive head and neck protection device coupled to the seat back;
- and
- an ejection initiation system, including:
- a pull handle coupled to the seat bucket;
- a first connector having a first end coupled to the pull handle;
- an ejection sequence initiation device configured to initiate an ejection sequence;
- a passive head and neck protection mechanism configured to activate the passive head and neck protection device;
- and
- an ejection pull connector having a first end and a second end, the second end coupled to the ejection sequence initiation device and to the passive head and neck protection mechanism.
An ejection seat, comprising:
- a seat bucket;
- a seat back coupled to the seat bucket;
- a passive head and neck protection device coupled to the seat back;
- a pull handle coupled to the seat bucket;
- a first connector having a first end coupled to the pull handle;
- an ejection sequence initiation device configured to initiate an ejection sequence;
- a passive head and neck protection mechanism configured to activate the passive head and neck protection device;
- and
- an ejection pull connector having a first end and a second end, the second end coupled to the ejection sequence initiation device and to the passive head and neck protection mechanism.
A method of initiating an ejection sequence, comprising:
- receiving, via a passive head and neck protection mechanism and an ejection sequence initiation device, an ejection sequence initiation signal in response to a pull handle coupled to a seat bucket being pulled, the seat bucket coupled to a seat back and the seat back coupled to a passive head and neck protection device, wherein the pull handle is further coupled to an ejection pull connector that is pulled in response to the pull handle being pulled and initiates the ejection sequence initiation signal;
- deploying, via the passive head and neck protection mechanism, a passive head and neck protection device in response to the ejection sequence initiation signal;
- and
- initiating, via the ejection sequence initiation device, the ejection sequence, after deploying the passive head and neck protection device, in response to the ejection sequence initiation signal.
