Koch’s ACES II ejection seat Ballistic Powered Inertia Reel (K‑ BPIR) is a torso restraint haul‑back device that, by means of a ballistic charge (gas generator), forcefully retracts a pilot firmly against his seat back during ejection.

It is designed as a direct replacement assembly for aircraft that use the ACES II ejection seat (i.e. A‑10, B‑1, B‑2 F‑15, F‑16, F‑22, and F‑117.) The K‑ BPIR has been demonstrated to require no seat or aircraft modifications for installation. K‑BPIR performance is well within the minimum specification requirements of MIL‑R‑ 8236 and has been demonstrated to be very repeatable.

This reel is fully supported by Koch to insure customer satisfaction and has a predicted ten‑year operational life.
