Schroth Profi II ASM Four-Point Harness
Featuring Proprietary Anti-Submarine Technology
The Schroth Profi II ASM Four-Point Harness integrates Schroth’s unique ASM (Anti-Submarining) technology in a four-point restraint system. That makes the Profi II ASM the ideal harness for use with OEM car seats not designed with a pass-through for sub straps.
Schroth’s ASM technology uses an extra fold of material sewn into the inboard shoulder belt which, in an impact, will elongate at a slightly different rate than the outboard belt. This allows two movements: in the initial jolt forward, the upper torso can twist very slightly so that, as the body rebounds from that initial jolt, the torso is planted firmly back into the seat rather than sliding ("submarining") under the lap belts.
Configurable Pull-Up or Pull-Down "Flexi" Lap Belts
The Schroth Profi II ASM 4 Point Harness has lap belts with Schroth's unique “Flexi Belt” feature. Instead of being sewn into the harness, the cam latches and end fittings are wrapped, making configuration changes from pull-up to pull-down quick and easy. And you can easily add bolt-in brackets to the lap belts in place of the standard snap-in brackets if you need to.
The Schroth Profi II ASM Harness has 3-inch shoulder belts which work with any HANS or other FHR (Front Head Restraint) device. A single or dual sub-strap can be added to convert this belt into a 5- or 6- point harness system. The shoulders are ready to wrap around a roll bar, or snap-in or bolt-in attachments can be purchased.
Choose from Black, Blue, Red, or Silver and be sure to specify Driver or Passenger Side as the construction of each is slightly different.
