Seating

Seat size and spacing are critical to the proper use of a CSRS on a school bus. The number of CSRSs you CE White Seatcan fit on a school bus seat depends on the width of the seat. The width of the seat is defined as the distance of the seat from the aisle to the interior wall of the school bus. A seat of 39 inches or more can usually accommodate two properly secured CSRSs or one CSRS and one older child not requiring a CSRS. A seat less than 39 inches wide can safely accommodate only one CSRS. You might want to consider ordering seats of two different widths for a school bus that will be used exclusively to transport pre-school age children. One side of the bus could be equipped with seats 39 inches in width (accommodating 2 child safety seats) and the other with seats 30 inches wide (accommodating one child safety seat). This combination is a common configuration when a wider aisle is desired (see aisle width section below).

You may want to consider ordering school bus seats with built-in child safety seats. These seats are similar to the integrated child safety seats available in many passenger cars and mini-vans. They consist of a full-harness CSRS that accommodates children at least one year of age and weighing 20 to 50 pounds. The integrated seat can also be used to attach a rear-facing CSRS for infants less than one year of age and under 20 pounds. When not being used, the integrated seat folds into the school bus seat allowing the space to be used by other passengers.Maximum Seat Spacing

Any school bus seat that will be used with a CSRS needs to be spaced to the maximum spacing permissible under Federal Motor Vehicle Safety Standard (FMVSS) No. 222, “School Bus Passenger Seating and Crash Protection.” Crash testing has shown that the injury potential for children in CSRSs is reduced at maximum seat spacing. An additional benefit is that it provides easier access to the person responsible for properly securing the CSRS. Narrowly spaced school bus seats make it extremely difficult and sometimes impossible to secure CSRSs properly.

The distance between school bus seats directly affects the seating capacity of the vehicle. Therefore, if the vehicleMinimum Seat Spacing you are ordering will be used to transport pre-school age children in CSRSs, you must specify to the distributor that you need “maximum seat spacing allowed in FMVSS 222.” The distributor will determine how many seats can fit on the bus when allowing for maximum spacing and the number of rows that must accommodate CSRSs. If the vehicle you are purchasing only needs to accommodate CSRSs in the first few rows, you should order “maximum seat spacing allowed in FMVSS 222” for those rows only. If CSRSs will be used throughout the bus, all rows except for emergency exits should be ordered with maximum seat spacing allowed in FMVSS 222. (Note: A CSRS should never be secured in a school bus seat located in a row with an emergency exit door or window.)
