Proposed seat design of additional third-row seats

Guidelines for the construction and installation of after-market additional seats are provided under Vehicle Standard Bulletin (VSB) and VSB 5B. These VSBs (referred to as VSB 5) recognise three categories of additional seats: Category 1: Additional seats intended for use by adults; Category 2: Additional seats intended for use by children up to 12 years of age; Category 3: Additional seats intended for use by children up to 8 years of age. The NSW Centre for Road Safety has been examining the crash protection afforded by these seats. For children under 4 years old, our previous study found that a child occupant sitting in a child restraint on a Category 2 or Category 3 seat (Additional Seat) was better protected than a child occupant sitting directly on an Additional Seats, but was not as well protected as a child in a child restraint in a standard vehicle seat. There is also an issue for children aged between 4 and 7 because the space requirements for Additional Seats under VSB 5 make it impossible to meet the general requirement that children must be secured in a suitable approved child restraint or booster seat. Hence, some states in Australia have amended the laws allowing children aged between four and seven years to occupy these seats without using a child restraint or booster seat provided they are wearing a lap/sash seatbelt or a lap-belt in conjunction with a child safety harness. However, even when seated directly on the Additional Seat, the space requirements for VSB 5 may not be sufficient to ensure acceptable safety for children aged between 4 and 12 because they are at risk of being injured by striking the seat in front or the vehicle roof.
