Abstract
Abstract A baby carriage has a seat belt with an annular belt section and a flexible belt connecting section. The annular belt section has disengageable buckles at its opposite ends.

The flexible belt connecting section connects the annular belt section to the lower end of the backrest of the baby carriage with a fixed spacing between the backrest and the seat belt proper to prevent a child from standing up.
