The Equitable Occupant Protection Informal Working Group to GRSP pursues equitable and enhanced protection of a diverse population through robust regulatory solutions addressing rear-end and frontal impacts. Strategic goals include reducing injury risk for restraint systems, assessing currently not considered injury types with high frequency and risk of Permanent Musculoskeletal Impairment, and avoiding bias in protection. The group established task forces on rear impact seat assessment focusing on soft tissue neck injuries, virtual crash testing, frontal impact and restraint system requirements, and extension of assessment towards currently not considered injury types. Upcoming workshops are scheduled for June online, September in Munich, and November in Tokyo. Next steps include prioritization and categorization of identified topics into short-term, mid-term, and long-term timeframes within respective task forces.

The informal working group on Equitable Occupant Protection will hold its 16th meeting on 18 May 2026 from 10.00 to 12.00 CET via TEAMS. The preliminary agenda includes adoption of the agenda, approval of minutes from the 15th meeting, review of the Progress Dashboard, status review of task forces, a report to GRSP 79th session, discussion of upcoming meetings and workshops, and conclusion.

The IWG chair reviewed the 15th meeting to address strategic goals of equitable and overall enhanced protection of diverse populations in rear-end and frontal impacts, based on feedback from GRSP-78-07 and GRSP-78-08. Task forces are investigating submarining prevention, abdominal injury risks, Diffuse Axonal Injuries, lower extremity injuries, and neck injuries in frontal crashes, while considering occupants of different sizes, weights, shapes, and seat adjustments. Priorities include developing broader protection procedures over a range of scenarios and speeds rather than specific repeated requirements, with next steps involving prioritization and role definition within task forces before reporting to GRSP 79.

The 15th meeting of the UN GRSP IWG Equitable Occupant Protection was held on March 24, 2026, with 35 online participants. The agenda and minutes of the 14th meeting were approved. Two informal documents, GRSP-78-07 and GRSP-78-08, were presented to GRSP 78 and discussed. Three operational Task Forces on rear-end assessment, virtual crash testing, and frontal impact and restraint systems were reviewed. Each Task Force is invited to structure identified topics by prioritizing them and assigning a short, medium, or long-term horizon, and to map contributions within the Task Force clarifying roles and areas of expertise. The 16th IWG online meeting is scheduled for May 18, 10–12 CEST.
