How much force can a truck seat back cushion absorb during a collision?

Click For Summary
SUMMARY

The discussion centers on the force absorption capabilities of a truck seat back cushion during a collision, specifically comparing a 2011 Ford F-150 Super Cab and a 2015 GMC Yukon XL SLT. The calculated impact force from a collision at speeds between 45-55 mph ranges from approximately 52,696 N to 64,406 N (11,846 lbf to 14,479 lbf). The thickness of the seat cushion is noted as 2 inches, but the foam density remains unspecified, making it difficult to determine the exact force absorption. Participants emphasize the need for certified expertise for accurate assessments in real-life scenarios.

PREREQUISITES
  • Understanding of basic physics principles related to force and impact.
  • Knowledge of vehicle weights and collision dynamics.
  • Familiarity with material properties, specifically foam density and its impact on force absorption.
  • Awareness of safety standards and certifications related to vehicle safety equipment.
NEXT STEPS
  • Research the properties of different foam densities and their impact absorption capabilities.
  • Learn about vehicle crash test standards and methodologies.
  • Investigate the physics of vehicle collisions, focusing on force calculations and energy transfer.
  • Consult with certified automotive safety experts for real-world applications and assessments.
USEFUL FOR

Automotive engineers, safety analysts, and anyone involved in vehicle design or safety assessments will benefit from this discussion, particularly those focused on collision safety and force absorption mechanisms in vehicle interiors.

I do not know much about this, please help.
My truck seat back cushion is 2" thick. Truck A is ~5,700 lbs from google. 2011 f-150 super cab 6.5ft bed.
Truck B is ~5775. 2015 GMC Yukon xl slt.
If truck A is stopped and braked and truck B hits truck A going 45-55mph creating a force of 52,695.8758604 N- 64,406.07049606 N or 11,846.503133255 lbf -14,479.059385089lbf.
I am not sure what density the foam is but how much does it take away in force? I hope this makes sense. I will do my best to answer any questions.

I am afraid we cannot answer questions that look like a real-life accident. This has several reasons:
  • We do not have all the information.
  • We are not certified in any way and our comments would be of no legal value.
  • We cannot even verify the data.
  • It is impossible to provide a necessary description on the internet.
If you want a reliable comment then please contact a local certified expert who can directly inspect the situation.
