Patent No. EP4098514 (titled "Baby Carriage With A Collapsible Child Seat") was filed by Cybex on Feb 22, 2016. The application was issued on Jan 29, 2025.
A baby carriage comprising a frame and a collapsible child seat includes a backrest, a seat surface element, and one or more adapter elements for frame connection. A first locking element secures the seat surface element relative to the adapter elements; reducing the angle between the backrest and seat surface element releases this lock. A second locking element secures a child restraining element relative to the seat surface element; reducing the angle between the backrest and seat surface element also releases this lock. The child seat may feature distinct axes of rotation for the backrest/seat surface and the restraining element to distribute forces. Additionally, a displaceable first gear may disengage from the adapter or seat element to release the seat surface lock.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
