cg-lock seatbelt safety devices

CG Lock Seatbelt Safety Device in box

The CG-Lock is an innovative new product that allows the lap section of a standard 3-point seatbelt to be tightened and locked or cinched into place, providing around 80 percent of the controlling benefit of a full racing harness, whilst leaving the shoulder/sash section uninhibited.

The CG-Lock is a US designed and engineered invention, with worldwide patent protection.
Although originally developed to give 'weekend racers' and sports-car drivers better stability, control, and therefore lap times, the technology has also been proven to provide much greater safety than a standard seatbelt, while enhancing comfort for daily driving.

Most importantly, formal crash testing and real world experience have demonstrated that use of the CG-Lock reduces the potential for injury in frontal, lateral, and rollover vehicle accidents.

The CG-Lock has been designed and fully tested to not interfere with a seat belt's safety and normal function.

CG Lock Seatbelt Enhancement has many uses

Mobility Impaired & Medical Use

Disabled, Amputee's, Frail, Elderly, Posture, Back Pain, Pregnancy

Although originally developed to give sports-car drivers better control , customers soon made it clear that the CG-Lock was a valuable tool for those with lower limb disabilities or amputations.

For many mobility impaired drivers, body instability leads to tilting whenever a corner is turned, causing limited control of the vehicle and resulting in less confidence on the roads. For most types of disability where a hand controlled vehicle is used, the CG-Lock will get you back behind the wheel, stabilised and full of confidence to drive safely.

Unlike a full harness, the CG-Lock tightly secures only the pelvis. With hips secured, the upper body tends to be secure too.

For people with a regular curvature of the spine, the CG-Lock also helps create and maintain correct driving posture, eliminating lower back ache, a common problem for many drivers and passengers.

The CG-Lock is the only device that keeps your hips in the correct position, making sure your spine is correctly aligned and supported during your journey.

The CG-Lock is now being 'prescribed' by many top healthcare professionals including Physiotherapists, Osteopaths and Chiropractors, who believe that the device has reduced and in some cases eliminated back pain due to slouching after long periods of driving.

A physician should be consulted before using the CG-Lock as a treatment or prophylactic for any type of medical condition, including but not limited to hip replacement, scoliosis, back pain, muscle spasm, fatigue, and the like.

Emergency Services & Military

CG Lock is crash tested CG Lock is suitable for single pass seatbelt tongues only


Police, Ambulance, Fire, SES, Security, National Forces

Most emergency services personnel are expected to attend 'situations' in a fast or timely manner, without any real additional safety features in their vehicles over and above those found in most everyday vehicles.

The CG-Lock offers additional stability and control, as well as safety when high speeds are required.

Furthermore, CG-Lock offers the additional assistance for maintaining correct posture whilst operating a vehicle, reducing fatigue and the potential for progressive injuries that are caused by bad posture.


For the Off-Road Enthusiast.


  • You don't need to "hang on" when driving can keep your feet light on the pedals and your hands light on the wheel for better driving control, faster reactions, and less fatigue - no matter what angle you are at.
  • You are "one with the vehicle" can sense the vehicle movement better, react sooner, and "feel" your way through the tricky spots more easily.
  • You can lean out the window to see your wheels without un-belting.
  • Should you need to stop and remove your seat belt when your vehicle is on a steep grade or at an angle, you can use the CG-Lock to hold the belt in place, avoiding those situations where a fully retracted belt can not be fed out due to the angle of the vehicle.
  • You can avoid "bouncing" off the seat when traversing bumpy terrain, and slack has developed in the seat belt.
  • You can avoid "submarining" under the seatbelt on steep descents.

Performance Driving

For those people who use their daily driver for more than just getting from Point A to Point B, the CG-Lock offers unparalleled stability, control, comfort and safety. When installing (cutting, drilling, welding etc.) a full race harness is not an option, the CG-Lock can provide around 80% of the controlling benefit.

Whether you participate at track days, club days, autocross events, motorkhana's or legal off-street drag racing, the CG-Lock will provide you with additional stability and control, giving greater safety where high speeds are involved.

Once the CG-Lock is installed, you pull up on the shoulder harness of your seatbelt, and the lap belt portion gets "racing harness tight" and stays as tight as you want until you release it!
Simple, but what a difference it makes!


  • You don't need to "hang on" when driving can keep your feet light on the pedals and your hands light on the wheel for better driving control, faster reactions, and less fatigue.
  • You are "one with the vehicle" can sense the vehicle movement better, react sooner, and "feel" your way through the tricky spots more easily. You can sense wheel spin, hop and off-line movement better, react sooner, and "feel" your way to a straighter line and faster ET.
  • You are "nailed" to the seat so your clutch dump is faster... for more precise shifting.

SeatSnug Child Seatbelt Safety Enhancement - Award Winning SeatSnug Child Seatbelt Safety Enhancement Packaging SeatSnug Child Seatbelt Safety Enhancement in use

Part No. 2900

SeatSnug® is a first-of-its-kind seatbelt enhancement developed using the patented CG-Lock® technology to keep children in booster seats more secure, stable and comfortable.

This innovative new product enhances both the safety and comfort of children riding in booster seats. It allows the lap belt to be lightly tightened around a child's hips while riding in a vehicle, preventing seatbelt slack or looseness from developing.

By gently securing a child while riding in a booster seat, SeatSnug® substantially eliminates bouncing, rocking, tipping, falling over, submarining, and ejection, thus reducing the potential for injuries and death in vehicular accidents. At the same time, SeatSnug® improves child stability and comfort.

Easy to Install and Use!

Seatsnug is for single pass seatbelt tongues only

SeatSnug® slides over the (single-pass) tongue of your seatbelt making installation quick and easy.

Once installed just buckle your child and booster seat in, 'enable' the SeatSnug®, then pull on the shoulder/sash belt to tighten the lap portion of the seatbelt. SeatSnug® stays secure while leaving the shoulder/sash belt unrestrained for your child's routine travel activities.

Why Does Your Child Need SeatSnug®?

SeatSnug Child Seatbelt Safety Enhancement attached to seatbelt

Children in booster seats are at risk of injury and death due to seatbelt slack (looseness). The three-point seatbelt commonly used in motor vehicles, represents a compromise between safety and comfort. A three-point seatbelt allows slack to develop in the lap belt portion while children (or adults!) are riding in a vehicle. Seatbelt slack is acknowledged in the auto industry as a major contributor to injuries and deaths in vehicular accidents.

A loose seatbelt allows a child in a booster seat to bounce around, rock, tip, slide, and even fall over during normal vehicle maneuvering, which can result in injuries, such as a child's head being thrown against the side of the vehicle, as well as leading to child discomfort, including motion sickness.

In frontal impact accidents or during panic stops, a loose seatbelt can further lead to a child submarining under the lap belt. Loose lap belts are also contributors to children, whether in a booster seat or riding without a booster seat, ejecting out of the seatbelt in rollover accidents, allowing children to "fly around" the vehicle, resulting in the potential for severe injuries and even death—even though the seatbelt was buckled!

How Does SeatSnug® Work?

SeatSnug® can be easily and quickly clipped onto a vehicle's existing factory installed (single-pass tongue) seatbelt. Once a child in a booster seat is buckled up, the SeatSnug® can be 'enabled' and the lap belt may be lightly tightened around the child's hips by pulling up on the shoulder strap to more safely secure the child, without affecting the normal operation of the shoulder strap.

Thus, SeatSnug® enhances child safety while maintaining and enhancing comfort.

Seatnug installed on a seatbelt

The SeatSnug® is equipped with an "on/off" function (an "enable/disable" feature). Switching between these settings should only be done with the vehicle safely parked. The feature has been designed for ease of use for adults, but is almost impossible for a child to activate, thereby keeping restless children safely in their seat.

SeatSnug® incorporates the unique race-track proven, crash tested, and patented CG-Lock® Technology (visit for more insights about the CG-Lock).

The CG-Lock® technology received the US National Parenting Centre's Seal of Approval as a unique car safety device that stabilises children in booster seats to increase child safety and comfort.
