Testing Capabilities

FMVSS 207/210 – Type 1 Seat-Belts

(Section 571.207 S4.2a & 571.210 S5.1)

A force of 22,240 N (5,000-pounds) is applied to a seating position.  This force is maintained for a minimum of 10-seconds. In addition a force equal to 20X weight of seat is applied in forward longitudinal direction through CG of seat. Multiple position passenger seats are tested simultaneously. Capable of bench testing and in-vehicle testing.  Also capable of performing equivalent CMVSS test.
FMVSS 207/210 – Type 2 Seat-Belts

(Section 571.207 S4.2a & 571.210 S5.2)

 

A force of 13,344 N (3,000-pounds) is applied to lap & shoulder belt.  This force is maintained for a minimum of 10-seconds. In addition a force equal to 20X weight of seat is applied in forward longitudinal direction through CG of seat. Multiple position passenger seats are tested simultaneously.Capable of bench testing and in-vehicle testing. Also capable of performing equivalent CMVSS test.

FMVSS 207

(Section 571.207 S4.2 & S5.1)

A force equal to 20X weight of seat is applied through the CG of seat in forward longitudinal direction (S4.2a); rearward longitudinal direction (S4.2(b); and a moment of 373 newton meters about the SRP (S4.2d). Capable of bench testing and in-vehicle testing. Also capable of performing equivalent CMVSS test.

FMVSS 222 – Seat Bus Seat

Seat Performance Forward (S5.1.3-Passenger Seats & S5.2.3-Restraining Barriers)

When pushed in the forward longitudinal direction a school bus seat back or restraining barrier must absorb 452 joules (4,000 inch-pounds) of energy per seating position within 356mm (14-inches) of deflection. Capable of bench testing and in-vehicle testing. Also capable of performing equivalent CMVSS test.

Seat Performance Rearward (S5.1.4)

When pushed in the rearward longitudinal direction a school bus seat must absorb 316 joules (2,800 inch-pounds) of energy per seating position within 254mm (10-inches) of deflection. 

Seat Cushion Latching & Retention (S5.1.5)

 

School bus passenger seat cushions that are removable without tools or that flip up must have a self latching mechansim that will activate with a downward force on the seat cushion of no more than 216N (48.4-pounds) applied to the center of seat cushion.
All school bus passenger seat cushions shall not separate from the seat at any attachment point when subjected to an upward force of 5X weight of seat cushion.  This force is maintained for a minimum of 5-seconds.  Also capable of performing equivalent CMVSS test.

Quasi-Static Test (S5.1.6) - only applicable to school bus passenger seats with type 2 seat-belts

Force is applied in forward longitudinal direction to shoulder belt (small school bus & large school bus forces).

Buckle Side Length Limit (S5.1.7) - applies to school bus passenger seats with type 1 or type 2 seat-belts

All portions of the buckle/latchplate assembly must remain rearward of the limit plane defined in S5.1.7.1 (based on seat characteristics).

Head & Leg Protection Zone Impacts (S5.3) 

Any contactable surface of school bus passenger seat within the head protection zone must abosrb a minimum of 4.5 joules (40 inch-pounds) of energy and achieve a HIC value ≤ 1000 when impacted at 6.7 m/s (22 ft/s). Any contactable surface of a school bus passenger seat within the leg protection zone must of a resisting force ≤ 2,669N (600-pounds) when impacted at 4.9 m/s (16 ft/s).

Wheelchair Securement Anchorages (S5.4.1) & Wheelchair Occupant Restraint Anchorages (S5.4.3) 

Each wheelchair securement anchorage shall be capable of withstanding a force of 13,344N (3,000-pounds). Each wheelchair occupant restraint floor anchorage shall be capable of withstanding a force of 13,344N (3,000-pounds). An anchorage that supports more than one wheelchair position must withstand the force C number of wheelchair positions its supports.

FMVSS 225 - Child Restraint Anchorage Systems

S6.3, S8 (Tether Anchorages) & S9.4,  S11 (Lower Anchorages) 

Every user-ready tether anchorage withstand the application of a force of 15,000N (3,372-pounds). The lower anchorages of a child restraint system shall not displace horizontally more than 175mm (6.89-inches) when a force of 11,000N (2,473-pounds) is applied in the forward direction & no more than 150mm (5.91-inches) when a force of 5,000N (1,124-pounds) is applied in a lateral direction.
Capable of bench testing and in-vehicle testing. Also capable of performing equivalent CMVSS test (CMVSS 210.2)

OSCAR H-Point/Seating Reference Point Manikin

SAE J826

This capability provides the physical representation of the H-point/SRP of a seat which is an important element for the development, auditing, and benchmarking of seating packages and how a seating package interacts with the interior of a vehicle.

Durability/Vibration

A single axis vibration table is used to control acceleration, frequency, and displacment - allowing the capability to simulate and investigate how our seating products react to real world conditions.
