GRSG-113-11/Rev.1
Lateral Protection Devices (UN Regulation No. 73)

Discussion of the evolution of UN R73 with a proposal to update load requirements for lateral protection devices:

  • Application of a force of 3kN perpendicular to the device (as currently defined)
  • Max. strain under loading at 90mm over the 250mm most rearwards part
  • Max. strain under loading at 450mm on the other parts.

GRSG | Session 116 | 8-12 Apr 2019

43. The expert from France informed GRSG that the proposal to improve the performance level of lateral protection devices for a better protection of vulnerable road users was in progress and that more time was needed for investigations. GRSG agreed to remove, in the meantime, the item from the agenda of the next session.

GRSG | Session 113 | 10-13 Oct 2017

44. The expert from France presented an evolution study of UN Regulation No. 73 on lateral protection devices and proposed to review the test requirements with respect to the geometric and loading/displacement criteria (GRSG-113-11-Rev.1). Thus, he introduced GRSG-113-12 amending the geometric criteria and GRSG-113-13 amending the static force. GRSG welcomed the research study and the proposed amendments. GRSG noted general support and agreed to resume consideration of this subject at its next session in April 2018. The secretariat was requested to circulate GRSG-113-12 and GRSG-113-13 with official symbols and to keep GRSG-113-11-Rev.1 as a reference document.

GRSG | Session 115 | 9-12 Oct 2018

44. Recalling the discussion of GRSG at its previous meetings, the expert from France stated that more time was needed to find an agreement on the proposal to improve the performance level of LPD for a better protection of vulnerable road users (ECE/TRANS/WP.29/GRSG/2018/18). GRSG agreed to defer the discussion on this subject to its next session.
