Abstract

A vehicle includes a chassis and a seating system. The seating system includes a frame coupled to the chassis, a seat cushion supported by at least one of the frame and a floor of the vehicle, a first recoverable insert configured to provide a first energy attenuation response, and a second recoverable insert configured to provide a second energy attenuation response different than the first energy attenuation response. The seat cushion defines a cavity shaped to interchangeably receive either the first recoverable insert or the second recoverable insert to thereby selectively vary an energy attenuation provided by the seating system.

First claim

The invention claimed is:

1. A seating system for a vehicle, comprising:
a frame configured to be coupled to a chassis of the vehicle;
a seat cushion supported by at least one of the frame and a floor of the vehicle;
a first recoverable insert configured to provide a first energy attenuation response; and
a second recoverable insert configured to provide a second energy attenuation response different than the first energy attenuation response,
wherein the seat cushion defines a cavity shaped to interchangeably receive either the first recoverable insert or the second recoverable insert to thereby selectively vary an energy attenuation provided by the seating system, wherein the second recoverable insert includes an identifier configured to indicate that the second recoverable insert is installed within the cavity defined by the seat cushion, wherein the frame defines an aperture, and wherein the identifier includes a tag extending through the aperture and hanging below the frame.

2. The seating system of claim 1 , wherein the first recoverable insert defines an A-kit insert and the second recoverable insert defines a B-kit insert, wherein the B-kit insert provides a level of threat protection that is greater than a level of threat protection provided by the A-kit insert.

3. A seating system for a vehicle, comprising:
a frame configured to be coupled to a chassis of the vehicle;
a seat cushion supported by at least one of the frame and a floor of the vehicle;
a first recoverable insert configured to provide a first energy attenuation response; and
a second recoverable insert configured to provide a second energy attenuation response different than the first energy attenuation response,
wherein the seat cushion defines a cavity shaped to interchangeably receive either the first recoverable insert or the second recoverable insert to thereby selectively vary an energy attenuation provided by the seating system and wherein the frame defines an aperture and the second recoverable insert defines a passage that corresponds with the aperture, the aperture and the passage defining a flow path that places the second recoverable insert in fluid communication with an interior volume of the vehicle.

4. A seating system for a vehicle, comprising:
a frame configured to be coupled to a chassis of the vehicle;
a seat cushion supported by at least one of the frame and a floor of the vehicle;
a first recoverable insert configured to provide a first energy attenuation response; and
a second recoverable insert configured to provide a second energy attenuation response different than the first energy attenuation response,
wherein the seat cushion defines a cavity shaped to interchangeably receive either the first recoverable insert or the second recoverable insert to thereby selectively vary an energy attenuation provided by the seating system, wherein the frame includes a seat pan upon which the seat cushion is disposed, the seat pan defining a first aperture, and wherein the second recoverable insert forms a second aperture that corresponds with the first aperture.

5. The seating system of claim 4 , wherein the seating system includes a measurement system positioned to evaluate an available stroke of the second recoverable insert from below the seat pan by interengaging with the first aperture and the second aperture.

6. The seating system of claim 5 , wherein an inner volume of the second recoverable insert and a reference surface of the second recoverable insert cooperate to define the second aperture, wherein the measurement system is configured to engage the reference surface to evaluate the available stroke of the second recoverable insert.

7. The seating system of claim 6 , wherein the measurement system comprises at least one of a measuring tape, a calibrated measuring element, a string potentiometer, and a laser measurement device.
