Simpson Hybrid S 3-Point Head and Neck Restraint

CMS only carries this device with standard HANS post anchors as they're lightweight and easy to attach/detach.

The Hybrid S Head Restraint is FIA and SFI approved (when worn with a multi-point harness system) and is tested and shown to be compatible with 3-point harnesses used by Car Club enthusiasts and High Performance Driving Experiences. This allows Driving Instructors, Auto Manufacturing Test Engineers, and others in cars with 3-point harnesses to have added protection.

We are pleased to offer this great option for increased protection to this sector of the market. Bear in mind, however, that on a racetrack the best protection we believe is a Full-Containment Cockpit System that includes a full containment seat, Snell SA2015 or FIA 8860 rated helmet, FIA or SFI approved head restraint, and 6- or 7-point racing harness system.

INSTALLATION:

1. To use a Hybrid S with a 3-point seat belt system, the SAS (Seatbelt Anchoring System) is not used. (The SAS strap anchor loops hook into the buckle of a 5-, 6- or 7-point racing harness.)
2. Have the wearer put on the Hybrid S and get into the driver's seat. Follow the instructions on fitting the device to the wearer.
3. Engage the 3-point seat belt and sit in the normal driving position.
4. Have a helper apply gentle pressure to the top of the device, keeping the device stable during tether adjustment. The device should be in a comfortable position behind the driver’s back, against the seat cushion.
5. With the helper holding the device and the driver looking straight forward, hold the triangulated tether up to the anchors on the driver’s helmet. Adjust the side tethers so that the end fitting can be easily inserted into the helmet anchor without pulling down on the helmet. A comfortable adjustment on the side tether is to have about ¼” of slack in the tethers.
6. With the helper still holding the device down and the driver looking straight ahead, adjust the rear tethers so that there is ½” to 1” of slack. Test the amount of head movement by moving the head straight forward. The driver should have 1” to 2” of forward head movement before the slack is taken out of the tether. Remember when checking this not to rotate the head down; translate it straight forward. This should allow for plenty of head movement on track.
