Summary

Larger hip restraints and a central handhold are crucial for preventing passenger ejections in golf carts and Low Speed Vehicles (LSVs). Current designs are insufficient for ensuring safety during sharp turns.

Area of Science:

  • Vehicle Safety Engineering
  • Biomechanics
  • Human Factors

Background:

  • Golf carts and Low Speed Vehicles (LSVs) frequently cause passenger ejections during sharp turns.
  • Existing hip restraints and handholds in these vehicles are often inadequately designed to prevent ejections.

Purpose of the Study:

  • To determine the minimum size requirements for hip restraints to prevent passenger ejection.
  • To evaluate the effectiveness of a central handhold in enhancing passenger safety.
  • To provide recommendations for golf cart and LSV manufacturers to improve fleet safety.

Main Methods:

  • A simulation of a turning golf cart provided dynamic input.
  • A biomechanical model of an adult male was used to assess passenger response.
  • Various hip restraint and handhold configurations were analyzed.

Main Results:

  • Only the largest hip restraint geometries were effective in preventing passenger ejection.
  • Current restraint designs are generally insufficient for ensuring passenger retention.
  • A central handhold demonstrated potential to improve safety outcomes.

Conclusions:

  • Significant improvements in hip restraint size are necessary for effective passenger retention.
  • The addition of a central handhold is recommended for enhanced safety.
  • Implementing these design changes can substantially reduce passenger ejections in LSVs and golf carts.
