Z-LINE MODULAR SYSTEM

Design, safety and functionality are at the heart of innovation at CYBEX. The Base Z is the secure and variable base unit for the new CYBEX Z-Line Modular System, which offers maximum protection as well as comfortable, flexible use. The unique, innovative rotation mechanism of the Base Z allows the car seat to be swivelled to the side of the car door for easier entry and exit.

The Base Z is a particularly long-lasting solution. It accommodates two different car seats and so can be used by children up to 4 years of age. The CYBEX Platinum Modular System is quickly installed with a simple click.

WHY REAR-FACING?

For maximum safety, we recommend using the Sirona Z in a rear-facing position for as long as possible – 45 – 105 cm, max. 18 kg (from birth up to approx. 4 years).

Physicians, accident researchers, and consumer and health organizations recommend transporting babies and toddlers in rear-facing car seats. In most countries, car accidents are still the main cause of death for children older than 1 year of age. However, if children are transported rear-facing beyond Group 0+, the risk of injury is mostly stable in Group 1. This can be seen in statistics from countries with predominantly rear-facing transport in Group 1, such as Sweden.

It is important to consider the anatomy of babies and toddlers in the event of an accident. Unlike adults, a child’s head is quite large and heavy in proportion to their body, and accounts for about 25% of their total body weight. However, the neck muscles and the spine of a child are not yet fully developed. That is why they need particular support and protection in an accident. CYBEX developed the Sirona Z to provide infants and toddlers with maximum safety in the car. In an accident, the Sirona Z acts like a protective shield, especially protecting the neck and spinal area. The impact forces are distributed over the large area of the shell. This significantly reduces strain on your child’s neck, shoulder and head as well as their inner organs. Therefore, the Sirona Z greatly reduces the risk of physical injury in a frontal collision.

Functions

Integrated linear side-impact protection

The integrated L.S.P. System of the Sirona Z i-Size offers increased safety in the event of a side-impact collision. It reduces the force of a side-impact in combination with the energy-absorbing shell by approximately 25%.

Energy reduction technology (ER-Tech)

The Energy Reduction Technology of the Sirona Z i-Size offers increased safety for your child in the forward-facing position in the event of a head-on collision. The "ER-Tech" reduces the forces on the neck of a child during a front crash by more than 20%, compared to other existing 5-point harness systems.

Height-adjustable headrest

The adjustable headrest offers 12 positions for a customized adjustment as your child grows.

One-hand recline and rotation function​

The smart one-hand recline and rotation function makes it easy for parents to adjust the seat while keeping one hand free. For comfortable sleeping and travelling, the Sirona Z i-Size car seat offers 5 reclining positions when rear-facing and 3 reclining positions when
forward-facing.

Rotating mechanism including driving direction control (D.D.C.)​

The innovative 360° rotating mechanism provides a comfortable entry and exit position with less strain on parent´s backs. In addition it makes switching between rearward and forward-facing position easy.
The Driving Direction Control (D.D.C.)
prevents misuse of the forward-facing position
before the child has completed 15 months of age and has reached a minimum size of 76 cm.

Two-click installation with ISOFIX

A two-click installation with ISOFIX allows for simple installation and guarantees increased safety. In combination with the Base Z the car seat is secured using the car's ISOFIX system and requires no further fastening. An installation indicator also helps to prevent possible misuse.

Modular system - one base, two car seats

Stay flexible – as part of the Z-Line Modular System, the Sirona Z i-Size and the Cloud Z i-Size both fit onto the Base Z for a continuously safe ride from birth up to 105 cm, approx. 4 years.

Rear-facing car seat

A rear-facing car seat reduces the risk of injury in a head-on collision by more than 80% when compared to a forward-facing system car seat. Tests show that the force of an impact during a front crash is distributed evenly over a large area. CYBEX recommends rear-facing travel for children up to 105 cm, approx. 4 years.

5-Point harness system

Secure your child in the Sirona Z i-Size with ease, thanks to the central 5-point harness system.

Energy-absorbing shell

The energy-absorbing shell of the Sirona Z i-Size absorbs the forces of an impact and protectively covers the child.

Belt holder​

The magnetic belt holders make taking your child out of the seat easy.

Easy boarding position

Rotation Mechanism with Driving Direction Control: The innovative 360° rotating mechanism makes it easier to get your child in and out of the car, ensuring less strain on your back. It can be easily adjusted from rear- to forward-facing without having to remove and reinstall the seat. The Driving Direction Control (D.D.C.) provides added safety by preventing forward-facing use before your child has reached the minimum age and size requirements (at least 16 months old and 76 cm tall).

Maximum comfort in the car

Smooth Adjustment – One-Hand Recline Adjustment: For a restful slumber in the car, the Sirona Z offers 5 rear-facing upright and recline positions and 3 forward-facing upright and recline positions. Its 12-step height-adjustable headrest provides even more comfort. The one-hand upright and recline adjustment mechanism is quick and easy to use.

Rebound bar

The integrated rebound bar of the Sirona Z offers increased protection in the event of a rear collision.

360° rotating mechanism

Innovative 360° rotating mechanism provides a comfortable entry and exit position with less strain on parents’ backs.

Driving Direction Control (D.D.C.)

The Driving Direction Control (D.D.C.) prevents misuse in forward-facing use before the child is at least 16 months old and 76 cm tall.

FAQ

The Sirona S i-Size can be used for newborns and children from 45cm up to a height of 105 cm (maximum body weight: 18 kg). This roughly corresponds to an age of four years.

We at CYBEX strongly recommend that you replace a seat after any kind of accident. This is because tiny hairline cracks, which may not be visible to the naked eye, can appear in the plastic parts of a seat after an accident. These cracks can pose an increased risk to safety.

The Sirona S i-Size can be used for children up to a maximum body weight of 18 kg.

i-Size is a new European standard for car seats. It specifies, among others, that car seats have to be installed with ISOFIX, that infants must travel in a rearward facing position up to the age of 15 months and, for the first time, that side-impact protection is tested.

Please refer to the retailer where you bought your CYBEX seat. They will deal with the matter on your behalf.

It is important to check whether the Sirona i-Size is compatible with your vehicle before you purchase it. This is because the Sirona S i-Size is solely an ISOFIX seat and can only be installed in i-Size certified vehicles or in vehicles with ISOFIX anchorage points. Before purchasing the seat, please refer to the compatibility list on the CYBEX website to see whether the Sirona S i-Size is compatible with your vehicle or not.

You can order replacement parts from a specialist retailer near you. To find a store near you, simply go to the store locator on our website: http://cybex-online.com/de/retailer.html

Thick clothing prevents the harness from lying snugly against the body. This incorrect belt positioning could result in the harness slipping off the shoulder. For this reason, your child should wear everyday clothing. Thick clothing such as winter jackets should be avoided where possible. Once your child has been positioned in the seat, he/she can be covered with an extra blanket for warmth.

The Sirona S i-Size can also be used in cars without i-Size certification. However, it is important to emphasize that the vehicle must be fitted with ISOFIX anchorage points. Before purchasing the seat, please refer to the compatibility list on the CYBEX website to see whether the Sirona S i-Size is compatible with your vehicle or not.

The Sirona S i-Size is installed using the vehicle’s ISOFIX anchorage points. The one-click installation with the ISOFIX system is a simple way to install the seat in both, forward and rear-facing position and enhances safety. The integrated support leg ensures additional stability and absorbs the forces in case of an impact. A green indicator confirms the correct installation.

No, this seat is not approved for use on an airplane.

The Sirona S i-Size is solely an ISOFIX seat and can only be installed in vehicles with ISOFIX anchorage points or in i-Size certified vehicles. Please refer to the compatibility list on the CYBEX website to see whether the Sirona S i-Size is compatible with your vehicle or not.

The head of a young child is large and heavy in proportion to the rest of their body and their neck is relatively weak. A rear-facing child restraint supports the head and neck and is thought, therefore, to reduce the risk of neck injury. Although this remains a topic for research, European regulators are satisfied that by 15 months, the neck has developed enough strength to withstand the forces in a typical crash. For this reason, 15 months was set as the minimum age for rear-facing. However, many R129 child restraints are approved for longer rear-facing use, for example, by children up to 105 cm (around 4 years).

We would like to draw your attention to the fact that the Sirona S i-Size should be used in a rear-facing position for as long as possible for maximum safety. However, the seat can optionally be switched to forward-facing. To do so, the seat can be rotated the forward-facing position once the child has reached a min. height of 76 cm and is 16 months old.

In a Sirona S i-Size your child is secured with a five-point harness. The harness should be strapped tightly so that there is space for one hand between the harness and the body of the child. In a forward-facing position, this harness system is fitted with an Energy Reduction Technology, reducing the forces on the neck of a child during a front crash by approximately 20%, compared to other existing harness systems.

Relatively tall infants may rest their legs on the rebound bar. Bending the legs at the knee does not affect safety in any way. As long as the child has sufficient legroom we recommend using the seat in a rear-facing position, which exposes the child to less force in the event of a collision.

To provide the best possible protection, the telescopic L.S.P. protector nearest the door should be extended as far as possible. It is designed with two settings. If in the longest setting, the L.S.P. touches the vehicle door, then the first setting must be used instead. When the seat is installed in the middle seat, the linear side-impact protection (L.S.P. System) should not be pulled out.

Yes, side airbags may remain activated when using the baby seat.
