Abstract: Described is a child holding device, more particularly a stroller and/or child seat, comprising a setting device for setting a state of the child holding device, a locking mechanism comprising a first locking device and at least one second locking device for locking the state, and a manual, actuation device for actuating the first locking device and the at least one second locking device, wherein the actuation device is connected by means of a common force transmission device to the first locking device and the at least one second locking device.

Abstract: A child transport device system, such as a pram or child trailer or jogger system, for use in different modes, in particular for pushing or pulling transport of at least one child, comprising a child receiving device for receiving the at least one child, which is adjustable in at least two configurations, and at least one connection device, which is connectable to the child receiving device in at least one of the configurations of the child receiving device and is not connectable or is connectable only in an impeded manner to the child receiving device in at least one further configuration of the child receiving device.

Abstract: A pushchair seat for mounting on a pushchair chassis is comprised of a seating surface and a backrest, wherein the backrest has a distal section and a proximal section which can be rotated relative to the distal section in such a way that the backrest can be folded up from an unfolded backrest usage position into a collapsed backrest storage position.

Abstract: The invention relates to a stroller comprising a stroller chassis and a child receiving device for receiving at least one child. The child receiving device can be oriented in at least two different orientations, in particular a forwards orientation and a rearwards orientation, relative to the stroller chassis, wherein at least one receiving section of the child receiving device is movable, in particular at least partly pivotal, such that at least one first and second setting of the child receiving device can be set, and a coupling device is provided and designed such that a conversion from at least one first orientation of the child receiving device to a second orientation is blocked in at least one first setting of the child receiving device.

Abstract: Stroller frame comprising at least one electric motor, for assistively driving the stroller frame, at least one wheel connecting device, in particular wheel axle, and at least one battery module connected or connectable to the wheel connecting device, which in the assembled state is arranged at least partly outside the wheel connecting device and is arranged at least predominantly below a level of an upper end of the wheel connecting device or is arranged at least partly below the wheel connecting device.

Abstract: A foldable pushchair chassis, particularly a sport-model pushchair chassis, buggy chassis or similar vehicle chassis for children, comprising wheels and a push element for pushing the pushchair chassis, wherein said pushchair chassis can be brought at least into a lockable usage state and into a folded, lockable storage state, and a, particularly manual, actuation device is provided and configured such that during transfer from the locked usage state into the locked storage state, at least two locking procedures can occur, in particular both release of the locking in the usage state and adjustment of locking in the storage state, by means of a single first actuation of said actuation device.
