Product Description
Cybex Sirona Q I-Size Platinum
For children from bith and 45 cm to 105 cm, about 4 years

The new CYBEX Sirona Q i-Size complies with the new Europe-wide regulation for child seats, ECE R-129 (i-Size). She writes u.a. the attachment of child seats with ISOFIX and the rearward transport of children up to the age of 15 months. Transport physicians, accident researchers and consumer and health organizations - such. ADAC or Stiftung Warentest - recommend that children are also transported in rear-facing child seats.
In the new CYBEX Sirona Q i-Size, children can safely be transported backwards from 45 cm to a height of 105 cm (about four years). Thanks to the new, intelligent design, even larger children have enough legroom to sit comfortably. At the same time, the seat can easily be installed in small cars. Practical functions such as the one-handed seat and recline adjustment also make daily operations easier.

EASY IN AND OUT - 360 ° rotation
The sophisticated 360 ° rotating mechanism allows easy switching between backwards and optionally forward-facing positions - without the hassle of completing the back seat. In addition, a comfortable entry and exit position is possible because the seat can be turned with a handle to the side.

ONE-CLICK INSTALLATION BY ISOFIX - Directed both backwards and forwards
A one-click installation with ISOFIX provides both backwards and forwards for easy installation and guarantees increased safety.
The CYBEX Sirona Q i-Size is secured via the ISOFIX system of the car and without further buckling with the seat belt in both backwards and forwards. An integrated support foot additionally absorbs the forces of a frontal impact and provides extra stability. The one-click installation of the ISOFIX system reduces the risk of incorrect operation during installation to a minimum.

SEAT-TO-CHASSIS TECHNOLOGY - Direct connection between car and child seat
The innovative "Seat-to-Chassis" technology allows a direct connection between the seat ("seat") and the car body ("chassis").
In the event of an accident, the forces are transferred directly from the seat to the bodywork, which activates the safety features of the car and seat at the same time, initiating the process of energy reduction at the earliest possible stage of the accident. (Patent pending)

TELESCOPIC L.S.P. SYSTEM - Linear Side Impact Protection
Sirona Q i-Size offers the L.S.P. The system features adjustable, linear side impact protection that further increases safety in the event of a side impact. (Patent pending)
Whether directed forwards or backwards, the linear side impact protection (L.S.P.) of the CYBEX Sirona Q i-Size increases protection in the event of a side impact. The L.S.P. System can be individually adjusted to seat position and vehicle type and absorbs the forces resulting from a side impact, in conjunction with shoulder and head protectors.

ALTERNATIVELY ADJUSTED - For children from min. 16 months and 76 cm to 105 cm, about 4 years
Depending on the individual physique, there may be limited legroom for tall children in a backward sitting position.
Depending on your preference and your individual needs, the Sirona Q i-Size can be used for children aged 16 months and over and at least 76 cm in height and forward (up to a size of 105 cm).

THE FIRST I-SIZE CHILD SEAT WITH CATCHER - Safety without constriction
The continuously adjustable catcher with A.R.T. Technology (patent pending) cleverly reduces the risk of serious neck and neck injuries without restricting the child. Thanks to the integrated locking mechanism, the catcher no longer has to be fastened separately. In forward position, the child is secured with a continuously adjustable catching body. This system resembles an inflated airbag that absorbs the impact energy across the entire cushion. In forward-facing position, the load on the neck is significantly reduced compared to a conventional 5-point harness system. The new, integrated mounting system makes an additional buckling of the catching body with the seat belt unnecessary. (Patent pending)
