Proposal to introduce fire suppression systems for buses and coaches upon detection of fire in the engine and/or heater compartment.

UN R107 includes a provision to prevent a folding seat used by the crew from obstructing the view of the exterior rear-view mirror. In light of the proposed amendment to introduce camera-monitor systems into UN R46 (indirect vision), this proposal would extend the same treatment to CMS used in the place of rear view mirrors.

Proposal for a new paragraph 7.6.5.2. in Annex 3 to clarify that deactivation of emergency controls at speeds lower than 5 km/h should be permitted taking into consideration that the opening in emergency is ensured according to the provisions of paragraph 7.6.5.1. Paragraph 7.6.5.2. is renumbered and amended to correct the speed at which the control has to be reactivated. The amended paragraphs align the requirements to those on overnight-locking systems.

Proposal to clarify the requirements concerning the height of steps in vehicles which comply with Annex 8.

Incident reports confirm that occupants of exposed seats have been thrown forward during heavy braking or vehicle impact conditions, often sustaining head injuries from contact with the vehicle floor or other hard structure. Seats particularly affected are those located immediately to the rear of an open wheelchair or buggy space. This proposal aims to reduce this risk by extending existing requirements for exposed seats adjacent to step wells to apply to other exposed seats where there is a risk of the occupant being thrown forward.

Proposal to redefine the measurement criteria for determining appropriate seat spacing in order to address observed cases where adequate spacing is not achieved even though the current criteria are fulfilled. The type approval authorities of the member states of the European Union (TAAM) discussed the proper interpretation of the text of the Regulation in the case of seats with a central recess (sunken area) and decided that the text of the Regulation needed to be modified in order to provide an adequate method to measure the H dimension.

OICA concerns regarding the proposal to introduce fire suppression systems for buses and coaches upon detection of fire in the engine and/or heater compartment (document GRSG/2014/6/Rev.1).

Text of the proposal for fire suppression systems prepared by the Secretariat and incorporating documents GRSG/2015/6/Rev.1 and GRSG-108-45 as agreed by the GRSG during its 108th session.
